25 annoying Samsung Galaxy S6 problems, and how to fix them

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

Problems with turning on, flash, fingerprint scanner, and more

Problem: Won’t turn on

Some people have gotten a scare when their Galaxy S6 refused to turn on. Don’t panic. There’s probably an easy way around this.

Potential solutions:

  • Hold down the Power button for a good ten seconds and you should see the S6 reboot and come to life.
  • Try plugging it in with the original charger and cable it shipped with and leave for at least half an hour, then try holding down the Power button for ten seconds again.
  • See if you can get the recovery menu to come up by holding down the Power, Home, and Volume up buttons together until you see the Android mascot onscreen. Highlight reboot system now using the Volume buttons, and use Power to select it.
  • If your Galaxy S6 still won’t turn on, then it’s time to contact your carrier, retailer, or Samsung.

Bug: Flash always on

A few Samsung Galaxy S6 owners reported an issue where the LED flash seemed to be constantly on. It wasn’t full brightness, but looking at it in a dark room it was possible to discern a faint light coming from the LED flash. This sparked natural concerns about it draining the battery as well.


  • Samsung is aware of this problem and has worked out a solution, which should reach you as an OTA update. You can check in Settings > About device > Software updates. There is no other known fix for this problem.

Glitch: Fingerprint scanner not working

There have been a lot of reports of problems with the fingerprint scanner on the Galaxy S6. Several owners are reporting that the scanner has stopped recognizing their fingerprints, though it may have been working fine before, and they can’t get access to the phone. If you can’t remember your backup password, there are other ways to get access.


  • After it fails a few times, you should get the option to sign in with your Google account. Apparently, this might not work if you have 2-step Verification turned on. You’ll need to access your Google account on another device in order to turn it off. You’ll find it under My Account > Sign-in & security. Once that’s off, enter the details on your S6 and you should be able to unlock the phone.
  • If you signed up and remember the details, then head to Samsung’s Find My Mobile website. You can use the Unlock my screen feature to get access.
  • You could factory reset your S6, but this will completely wipe all data on the phone, so it’s really a last resort. If you want to do it, then start by turning the S6 off. Now press and hold the Power, Home, and Volume up buttons together until you see the Android mascot onscreen. Use the Volume down button to highlight wipe data/factory reset and the Power button to select it. Choose reboot system now when it’s done and set your S6 up from scratch.

Potential solutions:

  • Before you try the workarounds, it’s worth holding down the Power button for ten seconds to get the Galaxy S6 to restart. Try the fingerprint scanner again when the S6 comes back on.
  • Wipe the scanner with a clean cloth.
  • Try pressing firmly and, if that doesn’t work, try pressing very lightly.
  • If you set it up without a case on your S6, and then put a case on, it could be affecting the scanner. Try removing it and see if it makes a difference.
  • If you do manage to gain access, then go to Settings > Lock screen and security > Fingerprints and make sure that you add new fingerprints and delete the old problem ones. Make sure that you move your finger around to cover different angles when you are adding new fingerprints and use all four slots to maximize your chances of it working.

Issue: Screen sensitivity

Quite a few reports have surfaced about problems with the Galaxy S6 screen sensitivity. Most people are finding that it isn’t always registering touches, seemingly at random. A few people have found that specific areas of the screen seem to be worse than others. You can test by typing *#0*# into the dialer.

Potential solutions:

  • Start by turning it off and on again.
  • If you’re using a case or a screen protector, then it may be worth taking them off to see if it makes any difference.
  • You can check if an app is the likely culprit by booting into safe mode. Turn the phone off. Press and hold the Power button. As soon as the screen lights up, let go of Power and press and hold the Volume down button. It should say safe mode in the bottom left corner. You can reboot to get out of safe mode. If there are no problems in safe mode, then something you installed is probably causing the issue. You can try uninstalling things and testing one-by-one, or opt for a factory reset and install selectively. If you do factory reset, it may be wise not to restore a backup and just set the S6 up fresh instead, as you may reintroduce the problem.
  • If nothing has worked, then it’s time to contact your carrier, retailer, or Samsung and ask about a replacement.

There have been a few complaints about a persistent pop-up relating to terms and conditions for Enhanced features, Profile sharing, and Simple sharing. The problem is, if you decline the terms, they just pop up again later.

Potential solutions:

  • If you tap Agree the pop-up will go away, but that means you have agreed to the terms and conditions. You can still turn the features off via the Contacts app, by tapping on your profile, tapping your name, and turning Profile sharing and Simple sharing off.
  • You may be able to avoid accepting the terms by tapping Decline and then going into Contacts, tapping your name under My profile, then tap Profile sharing > Registered information. Tap More at the top right and select Deregister phone number.
  • Some people also report success, without accepting the terms, after a factory reset, but it’s a drastic step to take.
