The LG G4 Android smartphone, developed by LG Electronics as part of the LG G series, was released in April 2015.

Shortly after its release, issues were found that made the device unstable or inoperable, resulting in data loss. LG released a series of forced updates, which were automatically installed without the user's consent.[1]

Issues

Touchscreen

In 2015, it was identified that the G4 was experiencing touchscreen issues, leading to the device becoming unresponsive or restarting.[2] LG released several patches to address the issue, though some had to be pulled due to causing more problems for the device. By November 2015, LG released a series of software updates to address the issue.[3][4]

Boot looping

From around September 2015, users reported an issue with the device where it would continuously cycle between booting and restarting, rendering it inoperable (known as a "boot loop").[5] Initially appearing to affect only a small number of devices, the issue quickly spread, and by the end of 2015, it was apparent that it could afflict almost any model.

Users either complained that the devices were not receiving appropriate repairs or called on LG to acknowledge a major fault with the devices. In some cases, users launched online petitions calling on LG to address their concerns.[6]

In January 2016, LG acknowledged the hardware issue causing the boot loop and announced that they would repair or replace affected devices.[7] LG did not offer assistance with data recovery from affected devices.

It was identified that the fault was caused by detached solder joints between components, resulting in the loss of user data and complete interoperability issues with the affected devices.

Other issues

Other problems included:

  • Charging port death[citation needed]
  • Speaker function damage[citation needed]
  • Touchscreen not turning on with tap-to-wake, random LED-blinking notifications despite no new messages, and keyboard glitches, among other issues.[4]

Class-action lawsuit

LG settled one class-action lawsuit in the USA related to boot-loop issues, offering affected device owners either $425 in cash or $700 in store credit toward an alternative LG device.[8]
