12 annoying issues with the LG G2, and how to fix them

LG G2 Phone front home screen

We’ve seen some impressive moves in the market from LG in recent months, none more so than its flagship Android smartphone, the LG G2. We haven’t encountered any of these issues on our in-office G2s, but the G2 is available on many carriers and has a few different variations. There are always a few issues. Here are the most common bugs, glitches, and annoyances that G2 owners are reporting, and some advice on how to fix them.

Problem: Speaker volume too low

A number of LG G2 owners have had issues with the low volume of the speaker. Some have missed notifications because of it, and others are disappointed in the video volume. Unfortunately there’s no easy fix for this.

Potential solutions:

  • Start by making sure your speaker grill is completely clean. If headphones are the problem, give the earpiece a polish.
  • You could try using a volume control or boost app from the Play Store, but we haven’t found one yet that actually boosts the volume. They mostly just give you granular volume controls and let you set the volume for different things.
  • If you’re already rooted or willing to root your LG G2, you can try a volume boost MOD like this one at XDA Developers forum. Just make sure you follow the steps carefully and get the right files for your device.

Glitch: Bluetooth not connecting and disconnecting frequently

Quite a few people have had trouble with Bluetooth and the LG G2. There’s a range of different problems being reported, including a failure to connect, frequently dropping the connection, and poor quality audio when connected.


  • Try turning the Wi-Fi on your LG G2 off or changing the band you’re using. Some bands can interfere with Bluetooth.

Potential solutions:

  • If it keeps cutting out, there’s a chance the Battery saver is kicking in. Go to Settings > Battery > Battery saver and uncheck Bluetooth.
  • If the quality is poor, try checking the settings in your music app to make sure you have it on a high quality audio setting.
  • If it won’t connect, turn both the phone and the device you’re trying to pair off and on again.
  • Check the pairing instructions for your Bluetooth accessory or system. You might need to hold down a button or enable pairing mode.
  • There’s a limit to the number of Bluetooth profiles your phone can store. Try deleting unused ones and pairing again.

Issue: Blurry photos

There have been several complaints about the camera on the LG G2. Some owners are getting blurry photos, even in good lighting conditions. Much more common is blurring in low light conditions and noisy, slow video. Smartphone cameras are generally pretty poor in low light conditions, but there are a couple of things you can try.


  • If you can keep the LG G2 really steady in your hands, that’s the easiest way to eliminate blur.
  • Alternatively, you can switch to Normal mode and increase the ISO to get a faster shutter speed, but it’s a trade-off — you will get more noise in the photo.

Potential solutions:

  • If your shots are blurry in good lighting conditions, start by checking the lens is clean. Look at it closely to make sure it isn’t scuffed.
  • Make sure that you are giving the sensor time to focus. It might be a good idea to hold down the Volume down button and wait until the box turns green to indicate that it’s focused.
  • Don’t stick with the automatic settings. Experiment with the settings in the camera app and compare your results until you find a combination that works for you.

Glitch: Mobile data fails to connect


Some people have complained about issues with the LG G2 connecting to the mobile data network. This should occur automatically when you go out of Wi-Fi range, but it’s not working for everyone. Some owners are having trouble getting it to connect at all, even when they have a full signal.


  • Try turning Airplane mode on and then off again. The quickest way to do this is probably to hold down the Power button until you see the Turn on Airplane mode option, tap it and then tap OK. You can also get to it via Apps > Settings > Tethering & networks > Airplane mode.

Potential fix:

  • This issue was fixed in a recent software update. Check that you’re up to date by tapping Menu > All settings > General > About phone > Software update > Update now.

Malfunction: Slow charging

Quite a few people have had problems with the LG G2 taking a long time to charge, possibly even up to 8 hours to fully charge the battery. This is definitely not normal. A lot of people also get the slow charging notification.

Potential fix:

  • If you’re not using the original cable and charger that came with the phone, then start using it.
  • If you are using the original LG charger and cable, and still getting the slow charging problem, then it could be because one or other is faulty. Try switching the charger and see if it makes a difference, and if not, try switching the cable and see if it makes a difference.
