13 major LG G4 problems and ways to fix them

We’re big fans of the LG G4. It boasts a simply stunning display, an excellent camera, and a stylish design, but no device is perfect. A few issues and LG G4 problems have surfaced online. We’ve been reading up on the complaints and checking for solutions. These are the major issues we’ve uncovered so far, each with a suggested workaround or fix. We also had advice on the best LG G4 cases and some handy LG G4 tips and tricks.

Problems with random reboots, touchscreen, and lag

Glitch: Random rebooting and boot loop

If your LG G4 has been rebooting for no apparent reason, or getting stuck in a boot loop, then you’re not alone. There are a lot of reports detailing random reboots. LG acknowledged the boot loop issue as being caused by “loose contact between components.” There’s even a lawsuit against LG now about the boot loop problem. If your LG G4 keeps turning off unexpectedly and gets stuck in a boot loop, then you’re probably going to have to get a repair or replacement. If you’re just getting random reboots, then there are a few things worth trying first.

Potential solutions:

  • Sometimes a MicroSD card can cause problems like this. Try turning your LG G4 off and removing the SD card to see if it makes any difference.
  • Try clearing the cache partition. Go to Settings > General > Storage > Cached data and then tap OK to clear it. If you find that you can’t get there because your G4 keeps crashing, then try turning the phone off and pressing and holding Power, Volume up, and Home. Let go of Power when the G4 vibrates, but keep holding the other two until you see the Android recovery screen. Use the Volume down button to highlight wipe cache partition and the Power button to select it.
  • It’s worth checking safe mode to see if a third-party app might be your culprit. Press and hold the Power button, then tap and hold on Power off when it pops up. You should get the option to boot into safe mode. If the crashes are gone, then you know one of the apps you installed is probably the cause and you can try uninstalling them one-by-one, or skip to the next step.
  • You may as well try a factory reset if nothing else has worked. Customer support is probably going to ask you to try it anyway, before you can get a replacement handset. Make sure you back up anything precious first. Go to Settings > Backup & reset > Factory data reset > Reset phone > Delete all. If you’re stuck in a boot loop, then you can try pulling the battery out and replacing it after 30 seconds to see if will start it up normally. If you’re unable to get there because it keeps crashing, turn the phone off and press and hold Power and Volume down. When you see the LG logo, let go of Power and press and hold it again while continuing to hold Volume down. You should see the Factory data reset option now, and you can use Volume down to highlight Yes and Power to select it.
  • Your final option is to go contact your carrier, retailer, or LG and ask for a replacement. Quite a few people with this problem report that they had to get a replacement handset after being unable to find another solution.

Glitch: Touchscreen unresponsive

A lot of LG G4 owners have been complaining about touchscreen taps being delayed or just not registering at all. It seems that the touchscreen sensitivity is off and some taps are being missed. There have also been complaints about long-pressing for special characters being incredibly slow when using the keyboard. If you want to confirm whether you are suffering from the issue then try out the Multitouch Test app.

Workaround:

  • If your main problem is with the keyboard then you could try using something different, such as Google Keyboard or SwiftKey.

Potential solutions:

  • LG acknowledged that there is an issue here, with Buzz Jensen, LG’s Head of Marketing in the U.S. tweeting to tell users to update the LG Keyboard via Settings > General > About phone > Update center > App update. This should fix issues in the LG Keyboard, but it’s not going to help if you’re experiencing the issue in another app.
  • If you’re using a screen protector or a case then it could be worth removing them to test if it makes a difference.
  • Some people have found that the issue seems resolved or at least reduced after they toggled Force GPU Rendering in the Developer options menu. To unlock Developer options go to Settings > General > About phone > Software info and tap on Build number repeatedly until you see the message You are now a developer! Go back to Settings > General and you’ll see Developer options. Head in there and toggle Force GPU Rendering to see if it makes any difference for you.

Problem: Lag

Quite a few people have been complaining about lag on the LG G4. This may be linked to the touchscreen responsiveness problem, or it may be a separate issue. Most complaints are about lagging when waking the device or switching between apps. It’s a powerful phone that really shouldn’t be lagging, so there are a few things you can try to resolve this.

Workarounds:

  • You could try using a different launcher, such as Nova Launcher. Some people report less lag when not using the default LG launcher.
  • Some people report less lag after going to Settings > General and toggling Dual window off. This might help because long pressing on Back is a shortcut to Dual window.
  • You could try the old animation trick. Unlock Developer options by tapping on Build number several times in Settings > General > About phone > Software info. You’ll find Developer options in Settings > General and you can switch Window animation scale, Transition animation scale, and Animator duration scale to 0.5x or turn them off completely.

Potential solutions:

  • Disable or uninstall any apps or games that you aren’t using. You might want to try out Greenify and see if it can help your LG G4 run more smoothly.
  • It might be worth trying a factory reset. Make sure that you’re backed up and then go to Settings > Backup and reset > Factory data reset.
  • Plenty of owners are reporting lag-free LG G4 performance so it could be worth going back to your carrier, retailer, or LG and trying to get a replacement handset.
