50-426: The G5 received mixed reviews. The device was praised for its shift to all-metal construction, while maintaining its removable battery. However, the modular accessory system was criticized for its limited use cases and for its inability to perform hot swapping . LG's software, too, was panned for the quality of its customizations. The G5 is constructed with an aluminum unibody chassis; a "micro-dizing" process utilizing

100-408: A fingerprint reader —remains on the rear. The lower "chin" can be detached to remove or replace the battery and to install add-on modules. The battery plugs into these modules, which is reinserted to replace the stock "chin". The G5 includes a Qualcomm Snapdragon 820 system-on-chip and 4 GB of LPDDR4 RAM. It also includes 32 GB of internal storage, expandable via MicroSD card. The G5 has

150-464: A jog wheel for zoom, and a supplemental battery. The "LG Hi-Fi Plus" accessory is a collaboration with Bang & Olufsen which adds a DAC , an amplifier, Direct Stream Digital audio support and upsampling, and is bundled with B&O Play H3 earbuds. LG stated that it would allow the co-development of third-party "Friends" to integrate with the G5, although none were produced. The LG G5's overall design

200-450: A 5.3-inch 1440p IPS display. It has two rear-facing cameras; a 16-megapixel primary camera and an 8-megapixel 135-degree wide-angle camera. The rear camera also offers color spectrum sensor and infrared autofocus features. The G5 supports DisplayPort , HDMI , and Miracast . A lower-specification variation, LG G5 SE , is sold in some markets including Latin America and China. It includes

250-539: A Snapdragon 652 system-on-chip instead of the Snapdragon 820, and has 3 GB of LPDDR3 RAM (instead of 4 GB of LPDDR4). The LG G5 shipped with the Android 6.0.1 "Marshmallow" operating system. Citing confusion between removing shortcuts to apps and uninstalling them entirely, the G5's home screen does not have an "app drawer"; instead, it places all apps on pages of the main home screen, like iOS does. However, there

300-462: A b2b-focused property with an emphasis on small business. The subbrand "acts as a complementary source of information targeted specifically at businesses and decision makers," the company says. A related property, 5GRadar.com, is focused on the mobile industry. The newest brand extension – TechRadar Gaming, or TRG – was launched 17 December 2021 and aims to "sit at the intersection of hardware and gaming, leveraging strengths of existing brands to bring

350-452: A backplane connector. Although the speed of plugging cannot be controlled precisely, practical considerations will provide limits that can be used to determine worst-case conditions. For a typical staggered pin design where the length difference is 0.5 mm, the elapsed time between long and short pin contact is between 25 ms and 250 ms. It is quite practical to design hot-swap circuits that can operate at that speed. As long as

400-423: A circuit that limits the inrush current to an acceptable value that cannot damage the pins nor disturb the supply voltage to adjacent slots. The pre-charge circuit might be a simple series resistor , a negative temperature coefficient (NTC) resistor, or a current-limiter circuit. Further protection can be provided by a "soft-start" circuit that provides a managed ramp-up of the internal DC supply voltages within

450-420: A component between other live components, while mechanical engagement latches, handles, or levers may be used to assist in proper insertion and removal of devices that either require large amounts of force to connect or disconnect, or to assist in the proper mating and holding together of power and communications connectors. There are two slightly differing meanings of the term hot swapping . It may refer only to

500-441: A component is removed while it is being used, the operations to that device fail and the user is responsible for retrying if necessary, although this is not usually considered to be a problem. More complex implementations may recommend but do not require that the component be shut down, with sufficient redundancy in the system to allow operation to continue if a component is removed without being shut down. In these systems hot swap

550-542: A device to synchronize data with a computer, and to replace faulty modules without interrupting equipment operation. A machine may have dual power supplies , each adequate to power the machine; a faulty one may be hot-swapped. Important cards such as disk controllers or host adapters may be designed with redundant paths in order for these to be replaceable in case of failure without necessitating interruption of associated computer system operation. Machines that support hot swapping need to be able to modify their operation for

600-484: A kind of hot swapping called Edit and Continue, which is supported by C# , VB.NET and C / C++ when running under a debugger. Hot swapping is the central method in live coding , where programming is an integral part of the runtime process. In general, all programming languages used in live coding, such as SuperCollider , TidalCycles , or Extempore support hot swapping. Some web-based frameworks, such as Django , support detecting module changes and reloading them on

650-443: A plastic primer was used to conceal seams required for the antenna. A rounded rectangular protrusion houses the camera components. The bottom houses a USB-C connector; this connector supports USB 2.0 data transfer (compatible with USB 3) and Quick Charge 3 fast charging. Unlike previous LG G models, which had volume buttons on the back, the G5's volume controls are on its side bezel, but the circular power button—which also contains

700-709: A splashy launch party at the club Tao in The Venetian Hotel during the CES show in 2013. It further expanded to Australia in October of 2012. It was the largest consumer technology, news and review site from the UK as of 2013. TechRadar also has licensed versions in Italy, Spain, Germany, France, Norway, Sweden, Denmark, Finland, the Netherlands and Belgium. The Indian and Middle East versions of

750-450: A temporary short-circuit to ground. This can cause unwanted ground-level pulses on the signals which can disturb the operation of other hot-swap components in the system. This was a problem for early parallel SCSI disk-drives. One common design solution is to protect bussed signal pins with series diodes or resistors. CMOS buffer devices are now available with specialized inputs and outputs that minimize disturbance of bussed signals during

800-557: Is a setting to enable the app drawer on the home screen. The LG software includes an "always-on display" feature, which persistently displays a clock and notifications on-screen when the device is in standby. The G5 does not support Android Marshmallow's "adoptable storage" feature. An upgrade to Android 7.0 "Nougat" was released in November 2016, followed by a final upgrade to Android 8.1.0 "Oreo" in September 2018. LG supports unlocking

850-446: Is inserted. Hot swapping is used whenever it is desirable to change the configuration or repair a working system without interrupting its operation. It may simply be for convenience of avoiding the delay and nuisance of shutting down and then restarting complex equipment or because it is essential for equipment, such as a server , to be continuously active. Hot swapping may be used to add or remove peripherals or components, to allow

900-421: Is normally used for regular maintenance to the computer, or to replace a broken component. Most modern hot-swap methods use a specialized connector with staggered pins, so that certain pins are certain to be connected before others. Most staggered-pin designs have ground pins longer than the others, ensuring that no sensitive circuitry is connected before there is a reliable system ground. The other pins may all be

950-453: Is semi-translucent and features a window for the always-on portion of the screen. Touch inputs can be made through the cover and semi-translucent screen for actions such as accepting calls. A line of accessories for the G5 branded as "Friends" were initially unveiled alongside the phone itself, including a wired head-mounted display known as the LG 360 VR (which attaches via the device's USB-C port),

1000-726: Is the express ability to pull a Universal Serial Bus (USB) peripheral device, such as a thumb drive, external hard disk drive (HDD), mouse, keyboard, or printer out of a computer's USB slot or peripheral hub without ejecting it first. Most smartphones and tablets with tray-loading holders can interchange SIM cards without powering down the system. Dedicated digital cameras and camcorders usually have readily accessible memory card and battery compartments for quick changing with only minimal interruption of operation. Batteries can be cycled through by recharging reserve batteries externally while unused. Many cameras and camcorders feature an internal memory to allow capturing when no memory card

1050-455: The PCB . Hot-swappable keyboards instead have a socket in its place that allows the switch to be freely replaced without re-soldering. Due to hot-swappable keyboards being less common, they often require being custom built or bought from custom keyboard manufacturers. They can be found in a variety of sizes and layouts , including more specialized ergonomic layouts. Hot swapping can also refer to

1100-522: The Cam Plus. However, The Next Web praised the design for "solving" the historic exclusion of user-replaceable batteries from metal phones, noting that "at least having the option for customizability is pretty awesome, not to mention replacing your battery after its capacity drops in a year or two. That's something no other metal smartphone can claim." However, the metal case does not permit wireless charging, supported by earlier "G" series phones. The display

1150-453: The DC power supply voltage. ESD effects can be reduced by careful design of the mechanical package around the hot-swap component, perhaps by coating it with a thin film of conductive material. Particular care must be taken when designing systems with bussed signals which are wired to more than one hot-swap component. When a hot-swap component is inserted its input and output signal pins will represent

1200-467: The G4 line were also present in the G5, and the G4 lawsuit against LG was amended to include the G5, among other models. The Canadian model is not part of this suit, leaving Canadian uses without redress for defective units. Hot swapping Hot swapping is the replacement or addition of components to a computer system without stopping, shutting down , or rebooting the system; hot plugging describes

1250-547: The G4, which used a model with reduced core count to avoid the overheating issues of the Snapdragon 810. TechRadar felt that the G5's performance was on par with the Snapdragon 820-based version of the Samsung Galaxy S7 sold in the United States, and that "in day-to-day use, and when not directly compared to its rivals' performance in a lab, it feels super slick." The modular accessory system received mixed reviews due to

1300-500: The G4. TechRadar was also mixed on LG's decision to re-locate the volume keys back to the bezel but maintain the rear-mounted power button as a fingerprint reader, noting that front and side-mounted fingerprint readers were easier to use—especially if the device is sitting flat. Due to its use of the Qualcomm Snapdragon 820 system-on-chip, the G5's specifications were considered to be more competitive than other flagships, unlike

1350-551: The LG 360 Cam virtual reality camera, and the LG Rolling Bot; these ultimately did not become available. These accessories are all managed via the LG Friends Manager application on the device, which automatically pairs and synchronizes with these devices. Two accessories utilizing the expansion slot system were unveiled; the "LG Cam Plus" accessory adds a grip to the rear of the device that incorporates physical camera controls,

1400-405: The ability to add or remove hardware without powering down the system, while the system software may have to be notified by the user of the event in order to cope with it. Examples include RS-232 and lower-end SCSI devices. Some implementations require a component shutdown procedure prior to removal. This simplifies the design, but such devices are not robust in the case of component failure. If

1450-488: The ability to alter the running code of a program without needing to interrupt its execution. Interactive programming is a programming paradigm that makes extensive use of hot swapping, so the programming activity becomes part of the program flow itself. Only a few programming languages support hot swapping natively, including Pike , Lisp , Erlang , Smalltalk , Visual Basic 6 (not VB.NET ), Java and most recently Elm and Elixir . Microsoft Visual Studio supports

1500-502: The addition of components only. Components which have such functionality are said to be hot-swappable or hot-pluggable ; likewise, components which do not are cold-swappable or cold-pluggable . Most desktop computer hardware , such as CPUs and memory, are only cold-pluggable. However, it is common for mid to high-end servers and mainframes to feature hot-swappable capability for hardware components, such as CPU , memory, PCIe , SATA and SAS drives. An example of hot swapping

1550-403: The bootloader of certain G5 models. This allows them to be rooted , and allows custom ROM images to be installed. Several independent custom ROMs continued to be developed for some G5 versions independently of LG; for example LineageOS 20 (based on Android 13) continued to be developed as of August 2023. The "Quick Cover" accessory was unveiled prior to the unveiling of the device itself; it

1600-462: The changed configuration , either automatically on detecting the change, or by user intervention. All electrical and mechanical connections associated with hot-swapping must be designed so that neither the equipment nor the user can be harmed while hot-swapping. Other components in the system must be designed so that the removal of a hot-swappable component does not interrupt operation. Protective covering plates, shields, or bezels may be used on either

1650-500: The company described as a relaunch. The redesign aimed to enhance user navigation, with a shift from story-type to product category-based navigation. Lance Ulanoff is the current US Editor in Chief and Marc McLaren is the UK Editor in Chief. Previous editors include Paul Douglas, Gareth Beavis, Darren Murph, Patrick Goss and Marc Chacksfield. TechRadar Pro, an arm of the main site, is

1700-430: The component. A typical sequence for a hot-swap component being plugged into a slot could be as follows: Hot-swap power circuits can now be purchased commercially in specially designed ASICs called hot-swap power managers (HSPMs). Circuitry attached to signal pins in a hot-swap component should include some protection against electrostatic discharge (ESD). This usually takes the form of clamp diodes to ground and to

1750-667: The fly. However, although the same as hotswapping for most intents and purposes, this is technically just a cache purge, triggered by a new file. This does not apply to markup and programming languages such as HTML and PHP respectively, in the general case, as these files are normally reinterpreted on each use by default. There are a few CMSes and other PHP-based frameworks (such as Drupal ) that employ caching, however. In these cases, similar abilities and exceptions apply. Hot swapping also facilitates developing systems where large amounts of data are being processed, as in entire genomes in bioinformatics algorithms. The term "HOT PLUG"

1800-459: The grounds are in the corners and the power pins are near the center. Two sense pins are located in opposite corners so that fully seated detection is confirmed only when both of them are in contact with the slot. The remaining pins are used for all the other data signals. The DC power supplies to a hot-swap component are usually pre-charged by dedicated long pins that make contact before the main power pins. These pre-charge pins are protected by

1850-433: The hot-swap connector is sufficiently rigid, one of the four corner pins will always be the first to engage. For a typical two-row connector arrangement this provides four first-to-make corner pins that are usually used for grounds. Other pins near the corners can be used for functions that would also benefit from this effect, for example sensing when the connector is fully seated. This diagram illustrates good practice where

1900-445: The hot-swap operation. If all else fails, another solution is to quiesce the operation of all components during the hot-swap operation. Modern day radio transmitters (and some TV transmitters as well) use high power RF transistor power modules instead of vacuum tubes . Hot swapping power modules is not a new technology, as many of the radio transmitters manufactured in the 1930s were capable of having power tubes swapped out while

1950-469: The limited number of modules designed for it, as well as the inability to hot swap modules due to the design of the system, which requires the removal of the battery. The accessories themselves also received mixed reviews; TechRadar felt that the Cam Plus and the Hi-Fi Plus did not justify their high price, and affected the device's size, but that it was "satisfying to set autofocus by half shutter key" with

2000-402: The removable components or the main device itself to prevent operator contact with live powered circuitry, to provide antistatic protection for components being added or removed, or to prevent the removable components from accidentally touching and shorting out the powered components in the operating device. Additional guide slots, pins, notches, or holes may be used to aid in proper insertion of

2050-827: The same length, but in some cases three pin lengths are used so that the incoming device is grounded first, data lines connected second, and power applied third, in rapid succession as the device is inserted. Pins of the same nominal length do not necessarily make contact at exactly the same time due to mechanical tolerances, and angling of the connector when inserted. At one time staggered pins were thought to be an expensive solution, but many contemporary connector families now come with staggered pins as standard; for example, they are used on all modern serial SCSI disk-drives. Specialized hot-plug power connector pins are now commercially available with repeatable DC current interruption ratings of up to 16 A. Printed circuit boards are made with staggered edge-fingers for direct hot-plugging into

Manufacturers specifically warned against such practices in the owner's manual or on the game cartridge. It was supposedly for this reason that Stop 'N' Swop was taken out of the Banjo-Kazooie series . With the Sega Genesis/Mega Drive system, it

2200-470: The transmitter is properly chosen for the conditions at the transmitting site. Power limitations: Although most contemporary video game systems can interchange games and multimedia (e.g. Blu-rays ) without powering down the system, older generations of systems varied in their support of hot-swapping capabilities. For example, whereas the Sony PlayStation and PlayStation 2 could eject a game disc with

2250-507: The transmitter was running—but this feature was not universally adopted due to the introduction of more reliable high power tubes. In the mid-1990s, several radio transmitter manufactures in the US started offering swappable high power RF transistor modules. The reintroduction of power modules has been good for the radio transmitter industry, as it has fostered innovation. Modular transmitters have proven to be more reliable than tube transmitters, when

2300-562: Was praised for being more useful than that of the Galaxy S7 due to its support for displaying all notifications, and not just specific types. The Next Web lamented LG's removal of the Dual Window feature—albeit believing the removal may have been due to the inclusion of native dual window functionality on Android Nougat , and that LG's customizations were "all around less useful than Samsung's". LG smartphone bootloop issues that mainly plagued

2350-403: Was praised for its brightness, although The Next Web felt that its color temperature was too cool, producing a "distractingly blue-green hue" that was exacerbated by the prominent use of white in its user interface. The software of the G5 also received mixed reviews, with particular criticism directed to the removal of the app drawer from LG's default home screen. The always-on display on the G5

2400-423: Was praised for its shift to a metal construction. The Next Web was critical of its design, arguing that the rear of the phone looked too "boring" because it was simply a rounded rectangle with a camera enclosure and power button that "protrude in an oddly wart-like manner" and a visible seam for the chin, and noting that the lack of curvature and its "hollow" feel made the design of the G5 "less premium" than that of

TechRadar TechRadar is an online publication owned by Future plc and focused on technology. It has editorial teams in the US, UK and Australia and provides news and reviews of tech products and gadgets. It was launched in 2008 and expanded to the US in January 2012, holding

2500-406: Was sometimes possible to apply cheats (such as a player having infinite lives) and other temporary software alterations to games by hot swapping cartridges, even though the cartridges were not designed to be hot swappable. Hot-swappable keyboards enable changing the switches without having to disassemble the keyboard. On standard mechanical-switch keyboards, the switch is directly soldered to
