The LG G4 is a great phone, but like any complicated bit of gadgetry it can encounter the odd issue such as weird bugs or performance problems. Never fear, though: AndroidPIT is here! Here are some common LG G4 problems and how to fix them.
You’re not imagining this one: LG’s head of US marketing tweeted advice to users, telling them to update the LG keyboard in Settings > General > About Phone > Update Center > App Update. That’ll only fix problems if you’re experiencing them in the LG keyboard, of course.
It sounds basic, we know, but screen protectors are often the issue: if your protector is fairly thick or hasn’t been applied too well it can make your touchscreen feel a lot less responsible.
LG G4 problem: it’s slow and laggy
There’s no reason why the G4 should suffer from performance problems: it’s virtually brand new and packed with power. We’d recommend starting with apps: download and install Greenify to see what apps are running on your G4. You might be surprised by what’s going on without you noticing.
It’s always worth trying Developer Options (go into Settings > General > About Phone > Software Info and tap Build Number seven times) and then setting Window Animation Scale, Transition Animation Scale and Animator Duration Scale to zero or to 0.5x to speed up the interface.
Some users report improvements after turning off Dual Window and other LG goodies in Settings > General, while others reckon it’s the launcher - so a third party launcher such as Nova Launcher may solve your woes. If all else fails, a factory reset should put your phone back to factory-fresh condition. Make sure you’ve got a backup of anything important and then hit Settings > Backup and Reset > Factory Data Reset.
It’s worth mentioning that these fixes only apply to touchscreen with intermittent issues. If the problem is consistent across the entire screen, you may have a hardware fault.
LG G4 problem: the LED of mystery
In a classic case of “the lights are on but nobody’s home”, some G4s are apparently flashing the LED light all the time, for no good reason. You could always disable it completely, but before you do that (it’s in Settings > Sound and Notification) it’s worth disabling the alarm in Clock, turning the screen off and checking the LED is off too. If it is, you can go back in and enable the alarm again. That tip comes courtesy of the XDA Developers forum.
LG G4 problem: broken Bluetooth, wonky Wi-Fi
Is there a phone that hasn’t suffered from wireless problems? Landlines don’t count. Like other Android smartphones the LG G4 can suffer from erratic issues with Bluetooth and Wi-Fi. Rebooting things often solves the problem, and our old pal Settings > Wi-Fi enables you to forget networks and re-establish connections to make them behave again. It’s also worth checking Battery & Power Saving in Settings > General to see if that’s powering down your radios.
Don’t forget your router: over the years we’ve found that 99.999999999 percent of Wi-Fi problems can be solved by swearing at the router, giving it a kick and unplugging it for 30 seconds.
If you’re out and about make sure the problem isn’t that you’re trying to connect to a hotspot you don’t have an account for: that’s particularly true if you have bundled Wi-Fi with your phone contract, as sometimes that Wi-Fi is only available in a subset of the Wi-Fi providers’ hotspots. That one’s really annoying.
LG G4 problem: it feels like it’s about to go on fire
Assuming you haven’t left your G4 in the sun or near a wicked child with a magnifying glass, overheating is often a byproduct of really hammering the phone with apps such as 3D games. Your case might be contributing to the problem - phones are designed to be case-free, and heavy cases can interfere with heat dissipation - and it’s worth trying Safe Mode to see if the culprit is an app that’s misbehaving.
LG G4 problem: it isn’t charging very fast
This could be raised expectations: the G4 supports Qualcomm’s QuickCharge 2.0, but the charger you get with it isn’t a fast charger. There are also known incompatibilities with some third party fast chargers, so if you’re encountering issues with one it’s worth trying another charger (if you can) to see if the problem goes away.
