There are plenty of reasons to recommend the LG V10, but no phone is perfect and it can be frustrating when your device refuses to behave as it should. We’ve been digging around to uncover the most common complaints regarding the V10, many of which keep cropping up on user forums and around the Web. None of these LG V10 problems are insurmountable, so if you’re suffering from an issue, then try one of our suggested fixes or workarounds.
Quite a few LG V10 owners have expressed some disappointment in the battery life of their new device. It has a 3,000mAh battery, but with a high resolution 5.7-inch display — and that secondary display to power — it may not last as long as you’d hope. Thankfully, the V10 does charge up quickly, but there are also some ways to extend the battery life when you don’t have access to an outlet.
The battery is removable, so you could always buy a spare. You can buy an LG V10 battery from Amazon for $60. Spend an extra $20 and you could get a charger to charge up the spare battery without your phone, too.
The screen always has the biggest impact on battery, so set it to auto-brightness or turn the brightness down as far as you comfortably can.
You might also consider heading into Settings > Location and switching the Mode to Battery saving.
Some people found that battery life was further improved after turning off VoLTE in Settings > Call.
You could try disabling apps that you aren’t using. Carrier bloatware, in particular, can cause battery drain, but it’s also important to research the individual apps before you disable them. Go to Settings > General > Apps and scroll to the All tab to see everything that’s installed. Tap on apps you don’t want and uninstall or disable them.
Some apps can only be removed if you root your LG V10. Rooting will also give you the option to tweak performance in other ways and try different ROMs, but it may also void your warranty.
There’s a good chance that an app or apps are responsible for any unusual battery drain, particularly if you find that your LG V10 is overheating. You can take a look in Settings > Device > Battery to get an idea of what is guzzling the power. You can also test this idea by booting into safe mode. Hold down the Power button, then tap and hold Power off and tap Restart in Safe mode > OK. If your battery woes are gone in safe mode, then you need to go through your third-party apps and uninstall them one-by-one to find the culprit, or go straight for a factory reset and install selectively afterward.
Before you factory reset, try wiping the cache partition. Go to Settings > Storage > Cached data and tap Yes to delete it.
A few people report that a factory reset vastly improved their battery life. Make sure you back up everything important first, then go to Settings > General > Backup & reset > Reset phone > Erase everything > OK.
There’s a chance that you have a faulty battery. If nothing else seems to help, go to your carrier, retailer, or LG and ask about a replacement handset.
Next problem: Fingerprint sensor not working
Glitch: Fingerprint sensor not working
A lot of people have been complaining about the fingerprint sensor on the LG V10 not working properly. It should be fast and smooth, so if you find that it fails frequently, then there’s obviously something wrong. The best method seems to be to press the button and then leave your finger on the sensor to be scanned, and make sure that you’re touching the metal sides of the LG V10 as you do it. You should also make sure that your finger is clean and dry.
Cases are causing issues for some people. Try removing your case and see how well it works.
You can increase the chances of it working by rerecording your fingerprints and using the same finger for more than one recording. Go to Settings > Fingerprints & security > Fingerprints > Add fingerprint and record it from multiple angles. Now do the same process again for the same finger. Just make sure to keep changing the angle to increase the chances it will recognize it.
If you determine that the case you’re using is the problem, then you have a few different options:
Try deleting the stored fingerprint and set it up fresh with the case on the LG V10.
Some people think that the problem is a lack of contact with the metal sides of the V10. Try squeezing the sides of the case when you use the fingerprint sensor, or touch an exposed part of the sides if there is an opening.
Put some aluminum tape on the inside of the case, touching the sides where you naturally hold it when using the fingerprint sensor.
Some people report that a software update greatly improved their success rate with the fingerprint sensor. Check in Settings > About phone > Software version to make sure you’re up to date.
Next problem: Second screen light bleed
Issue: Second screen light bleed
If you notice that there’s light bleeding from the second screen on your LG V10, then you are not alone. Quite a few people have complained about this. If you want to check, then go into a dark room and take a look at the edges of your second screen when the main screen is off.
There really isn’t much you can do about this. A lot of people have suggested that there are differences between models based on manufacturing, but others claim that every LG V10 has this issue because of the separate backlight for the second screen (which should only come on when the main screen is off). Sometimes the light bleed is really noticeable, sometimes it isn’t, and it might be in the top left corner or in the right. For that reason, you might get an LG V10 handset with less bleed if you exchange it, but there’s obviously no guarantee. You may also find that your carrier or retailer might not want to acknowledge this as a fault, which could be a problem if you’ve gone past your no questions asked exchange period.
Next problem: Wi-Fi slow or keeps dropping
Problem: Wi-Fi slow or keeps dropping
Quite a few LG V10 owners have had problems with Wi-Fi networks. The phone may refuse to connect, the connection may be slow, or it might drop altogether from time to time. This is always a common issue with new phones and there are lots of different things you can try.
Turn your LG V10 and your router off, and then turn them on again. This often works, but it’s rarely a permanent fix.
Go to Settings > Wi-Fi, long press on your troublesome router, then tap Forget network and try setting it up from scratch.
Take a look in Settings > General > Battery and check that Battery saver isn’t interfering with your Wi-Fi.
Check in Settings > General > Smart Settings and make sure nothing in here is interfering with your Wi-Fi.
If you’re connecting to 5GHz and there’s a 2.4GHz option, or vice versa, try switching to see if it makes a difference.
Use a free app like Wifi Analyzer to make sure that your channels aren’t too crowded. If you find that you’re using a busy channel, then try switching to a different one.
Check that the MAC filter on your router is off, or add your LG V10 MAC address. You should find it listed in Settings > Wi-Fi > More > Advanced.
Make sure that Keep Wi-Fi on during sleep is set to Always. You’ll find it in Settings > Wi-Fi > More > Advanced.
Make sure that your router firmware is up to date. Check with your ISP or manufacturer about updates.
Next problem: High resolution YouTube videos freezing
Glitch: High resolution YouTube videos freezing
A lot of people are reporting that YouTube videos are freezing intermittently on the LG V10 when set to 1440p or a higher resolution. The picture will freeze, but the audio might continue. For some people this is consistent, but others are getting mixed results where it freezes at different points. There’s no obvious pattern, and some LG V10 owners don’t seem to be experiencing the issue at all.
You can switch to 1080p or lower, and the video should continue without a problem.
Some people have found that the problem is reduced if they download the video first, instead of streaming.
This might be related to the YouTube app. Make sure that it’s up to date and see if it makes a difference if you play the video via your browser.
Since some owners aren’t having problems, there’s a chance that a replacement handset will not suffer from the same issue, so you could try contacting your carrier, retailer, or LG. Even if you decide to stick with it, you should report the problem, so there’s more chance of a fix rolling out as some point.
