Problems with booting, backlight bleed, fast charging, and more

Issue: Bootloop

We have seen a handful of reports about the LG G5 getting stuck in a bootloop, where it continually restarts itself. This issue was widely reported for some other LG phones and it’s the subject of a lawsuit that includes the LG G5, though it does seem to be far less common on the G5 than it was on some of its predecessors.

Possible fixes:

  • Press and hold the Power and Volume down buttons at the same time until the device resets. This could take 30 seconds or more.
  • Try removing the battery, wait for a few minutes, and then replace it and boot the phone up again.
  • If you have a MicroSD card installed, try removing the battery and the MicroSD card, then replace the battery and boot the phone up again.
  • Your final option is a factory reset with the hardware keys, but if you do this, you’re going to lose any data that’s not backed up. To try it, hold the Power and Volume down buttons until you see the LG logo, then let go of Power, but keep holding Volume down. You should see the Factory data reset option and you can use Volume down to highlight Yes and Power to select it. You’ll see Erase all user data and restore default settings, and you can use Volume down to highlight Yes and Power to select it again.
  • If the issue persists after a factory reset, then contact LG and ask about a replacement.

Problem: Backlight bleed and blooming

There have been a number of reports about some issues with the LG G5 display. Some owners are reporting an unacceptable level of backlight bleed, with bright patches appearing at the edges or corners of the display. There are also some reports that the picture distorts or blooms when people press on the display. These complaints suggest some build quality or quality assurance issues with the first wave of G5 handsets to hit the market. If you want to test the backlight, you can use the free Backlight Bleed Test app.


  • If you find that the backlight bleed or blooming is bothering you, there’s really only one solution. You need to contact LG, your carrier, or your retailer and get a replacement handset.

Annoyance: Missing app drawer

By default, there’s no application drawer in the LG G5 user interface. Every app gets added to the home screen instead. Some people won’t miss the app drawer, but if you want it back on your LG G5, then you have a couple of options.


  • Go to Settings > Display > Home screen > Select Home and tap EasyHome. This will bring the app drawer back, but unfortunately, it will also simplify the interface and make your font bigger.
  • A better workaround is to install a third-party launcher. We recommend the Google Now Launcher or Nova Launcher, but there are many more great Android launchers in the Play Store to choose from.


  • Open up the LG SmartWorld app, which should be pre-installed on your LG G5, and search for LG Home 4.0. Download and install it, and you’ll find that you have an app drawer again.
  • LG did eventually release an update that brought the app drawer back. Go to Settings >About phone > Update center > App updates and look for Home & app drawer.

Issue: Fast charging not working as expected

The LG G5 supports the latest Quick Charge 3.0 standard, but there seems to be a bit of confusion about how it works. It’s designed to charge your phone quickly, taking it from 0 up to 80 percent in around 30 or 35 minutes. Once you hit 80 percent, it will charge at a slower rate. You can swipe down the notification shade to see a notification that indicates fast charging is working. If you find that the G5 isn’t charging up as fast as expected, then there are a couple of things to try.

Potential solutions:

  • Don’t use your phone while it’s charging. If you use the LG G5 while it’s charging, then it will significantly slow down the charging speed.
  • Make sure that you’re using a cable and charger that support Quick Charge 3.0. You can pick up an Anker QC 3.0 charger for $15 right now.

Glitch: Notification LED not always working

A few people have run into a glitch where the notification LED fails to light up for some incoming messages. It might work with the default apps, but not with some third-party messaging apps.


Potential solutions:

  • Go into Settings > Sound > Notification LED to make sure that the feature is toggled on and that you have the right notification types selected.

Problem: Poor battery life

A few people have been complaining about battery life with the LG G5, and weak battery life is something we noted in our LG G5 review. Keep in mind that during the first couple of days with a new phone, the battery will drain fast because it’s downloading and installing apps, and you’re probably using it a lot. If you find that the battery continues to drain rapidly after the first few days, then you may have a problem.


  • The obvious place to start is to turn features off. Pull down the notification shade and turn off anything you don’t need.
  • Go to Settings > Display and toggle Always-on display off.
  • Reduce your screen brightness. Go to Settings > Display > Screen timeout and turn it down as low as you can stand.
  • Use the power saving modes in Settings > Battery & power saving.
  • The LG G5 does have a removable battery, meaning you can always purchase a spare battery and pop it in when you need more power. You may also be able to get a second battery and charging cable for free as part of an ongoing LG promotion. Check your eligibility at this LG website.

Potential solutions:

  • If you find that your power is draining fast, even when you aren’t using the LG G5, you may have a problem app. Take a look in Settings > Battery & power saving > Battery usage. Is there a specific app guzzling a lot of power? Check out its settings or consider replacing it.
  • Get rid of your cached data by going to Settings > General > Storage. It will take a few seconds to calculate. When it’s done, tap on Cached data and Yes to clear it.
  • Your final option is to factory reset the LG G5, which will delete all settings and data. Back up your files first. When you’re ready, go to Settings > General > Backup & reset > Factory data reset and tap Reset phone > Delete all > OK.
