This behavior has also been noted during charging. Due to the device's metal battery cover, the handset tends to retain any heat generated. It has also been reported that the phone can reboot after reaching high temperatures. Upon rebooting, the phone can hang at the LG start-up logo, necessitating the user to reset the device manually.
When officially acknowledging the bootloop issues with the G4, LG stated that it was caused by a "loose contact between components"; Android Authority explained that "a loose connection between power supply or memory components could certainly cause a phone to fail to boot up properly, due to a lack of system stability or not being able to access vital memory.
When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or; if heat dissipation is poor, so that normally produced waste heat does not drain away properly.
Superheating can occur when an undisturbed container of water is heated in a microwave oven. At the time the container is removed, the lack of nucleation sites prevents boiling, leaving the surface calm. However, once the water is disturbed, some of it violently flashes to steam, potentially spraying boiling water out of the container. [6]
In radio-frequency engineering and communications engineering, a waveguide is a hollow metal pipe used to carry radio waves. [1] This type of waveguide is used as a transmission line mostly at microwave frequencies, for such purposes as connecting microwave transmitters and receivers to their antennas, in equipment such as microwave ovens, radar sets, satellite communications, and microwave ...
In microwave radio relay, a microwave transmitter and directional antenna transmits a narrow beam of microwaves carrying many channels of information on a line of sight path to another relay station where it is received by a directional antenna and receiver, forming a fixed radio connection between the two points. The link was often ...
A microwave oven does not pose this problem. Food and cookware taken out of a microwave oven are rarely much hotter than 100 °C (212 °F). Cookware used in a microwave oven is often much cooler than the food because the cookware is transparent to microwaves; the microwaves heat the food directly and the cookware is indirectly heated by the food.
LG was also an official supplier to Virgin Racing and Lotus Racing team, plus engine manufacturer Cosworth from 2010 to 2012. [88] LG also sponsors London Fashion Week and the LG Arena in Birmingham. [89] During the period 2001–2003, LG sponsored the snooker Grand Prix. During these years the tournament was known as the LG Cup. In 2008, LG ...
