You’re starting on page 2 of this, click here to start at the beginning.

Problems with LED, Bluetooth, Wi-Fi, and more

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.

Workaround:

  • You could just turn the LED off. You’ll find the option in Settings > Sound & notification > Notification LED.

Potential solutions:

  • 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.

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.

Workaround:

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.

Potential solutions:

  • 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.
  • Try using the Bluetooth Auto Connect app and see if helps.

Problem: Wi-Fi won’t connect or very slow

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.

Potential solutions:

  • 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.

Issue: Portrait photos rotating

If you find that your portrait photos from the LG G4 are sometimes being flipped to landscape orientation when you download them to another device or upload them online, then you’re definitely not alone. This seems to be something do with the way the LG G4 handles rotation. The phone uses EXIF (exchangeable image file format) settings to rotate the photo, which might be about cutting down processing time. There are a couple ways around the issue, but unfortunately there’s no real solution.

Workarounds:

  • Use a different camera app. There are loads to choose from in the Play Store.
  • Use an alternative gallery app. For example, saving photos in QuickPic Gallery, and then uploading them from there will fix the rotation issue.
  • You can always rotate the photos on your computer in Windows Photo Viewer, or using any editor.

Glitch: Green spot on photos

A number of people are reporting an emerging glitch where green spots appear in the photos they take with the G4’s camera. There are also reports of an issue with a pink tint in the center of low light photos, but it’s not clear if the two are linked. There’s some argument about whether this is a hardware or software issue.

Workarounds:

  • Try using an alternative camera app to take photos and see if there’s a difference.

Potential solutions:

  • Make sure there’s no protective film on the lens and remove your case, if you’re using one.
  • Some people found temporary success by going to Settings > General > Apps and finding the Camera app, then tapping Clear cache and Clear data.
  • If you’re able to, then it may be worth contacting your carrier, retailer, or LG to ask about a replacement.
