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.
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.
If your main problem is with the keyboard then you could try using something different, such as Google Keyboard or SwiftKey.
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.
Next 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.
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.
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.
Next problem: LED flashing, but no notification
Bug: LED flashing, but no notification
A few LG G4 users are annoyed because the LED keeps flashing for no discernible reason. When they check, there are no new notifications, and yet that light keeps blinking.
You could just turn the LED off. You’ll find the option in Settings > Sound & notification > Notification LED.
Here’s a fix from XDA Developers forum. Clear your notifications and turn off the screen, check that the LED is flashing. If it is then turn the screen back on and go to Clock, then disable Alarm. Turn the screen off again. The LED should have stopped blinking and you can go back into Clock and enable your Alarm again.
Next problem: Bluetooth won’t connect or not working properly
Issue: Bluetooth won’t connect or not working properly
Some people are having trouble getting the LG G4 to pair with their Bluetooth car system or device. There are also a few reports of missing song titles, and other issues related to Bluetooth.
If you’re having issues with song titles then try disabling the default LG Music app (assuming you’re using something else). You’ll find it under Settings > General > Apps on the All tab.
Take a quick look in Settings > General > Smart Functions > Smart Settings and make sure nothing in here is interfering with your Bluetooth.
Check your device or car manual and make sure that you’re following the instructions for pairing.
You may have reached some kind of Bluetooth profile limit. Try deleting old profiles on your car or device.
Go to Settings > Networks > Bluetooth on your G4, tap settings for the device that’s giving you problems and choose Forget. Do the same thing with your car or accessory, where applicable, and then set the connection up fresh.
Quite a few LG G4 owners have been struggling to get a stable connection to Wi-Fi networks. In some cases the phone won’t connect at all, but mostly it connects and runs slowly, or disconnects itself seemingly at random.
You should always start with the easiest potential fix, which is to turn your router off and turn your phone off and then turn them both back on again.
Now try going to Settings > Wi-Fi and long press on the network you are trying to connect to, then tap Forget and set the connection up anew.
Take a look in Settings > General > Battery & power saving and check that Battery saver isn’t interfering with your Wi-Fi.
Check in Settings > General > Smart Functions > Smart Settings and make sure nothing in here is interfering with your Wi-Fi.
If you’re connecting to the 2.4GHz band then try 5GHz instead and vice versa.
Download and install Wifi Analyzer and check how busy your channels are. You may need to switch to a less crowded channel.
Check in with your ISP or router manufacturer and make sure that your router firmware is up to date.
