We’ve been digging around to see what Galaxy S7 Edge problems are cropping up most often online. We’ve identified a few issues here, and we’ve got ideas on how to fix them or work around them. The first thing you’ll want to do, to safeguard that slippery, fragile, fingerprint-prone glass, is to snag one of the best Galaxy S7 Edge cases.
Glitch: Fingerprint scanner not working
Sometimes, you may find that your S7 Edge suddenly stops recognizing your fingerprints and you have to input your PIN or password to gain access. There’s no obvious cause for this. You may also find that entering new fingerprints doesn’t work. Here’s what to do:
- Start with a simple reset by holding down the Power and Volume down buttons together until your S7 Edge turns off. You might find the fingerprint sensor is back to normal after this.
- If it’s still not working, then try wiping the cache partition. Turn the S7 Edge off by holding the Power button and then tapping Power off. When it’s off, hold down the Power, Volume up, and Home buttons simultaneously until the device turns on. You can let go and you should see the Android icon and then the recovery screen. Use Volume down to highlight wipe cache partition and then Power to select it. Highlight yes and then Power again to select. When it’s done press Power to select Reboot system now.
- If the fingerprint scanner still doesn’t work after that, then it’s time to contact Samsung about a repair.
Problem: Horizontal gray translucent lines
A few people have reported a series of three or four gray translucent lines appearing horizontally on their S7 Edge screen. Unfortunately, this seems to be a hardware fault with the display.
- Swipe down from the top of the screen to open the notification shade and tap to tick the Auto box next to brightness, then drag it all the way to maximum. The lines shouldn’t be visible anymore, but maximum brightness is going to drain your battery pretty quickly.
- You could use an app like Twilight to apply a screen filter and see if you can reduce the effect.
- You must contact your carrier, retailer, or Samsung and get a repair or replacement handset.
Issue: S7 Edge keeps freezing or restarting by itself
A number of people have been frustrated by their S7 Edge freezing or restarting itself seemingly at random. There are a few different potential causes for this, so here’s what to try:
- There’s a good chance that an app you’ve installed is causing the problem. You can check by booting into safe mode. Press and hold the Power button, then tap Power off to turn the S7 Edge off. Press and hold the Power button past the first Samsung Galaxy S7 Edge screen, until you see the Samsung logo, then let go of Power and press and hold the Volume down When your S7 Edge starts up, it should say safe mode in the bottom left. If the problem is gone, then you know an app is to blame. You can exit safe mode by pressing and holding the Power button and tapping Restart. You can either uninstall apps one by one and test, or back up everything and go to Settings > Backup and reset > Factory data reset, then install apps selectively and test them again.
- If that didn’t help, then try wiping the cache partition. Turn the S7 Edge off by holding the Power button and then tapping Power off. When it’s off, hold down the Power, Volume up, and Home buttons simultaneously until the device turns on. You can let go when you see the Android icon and then the recovery screen should appear. Use Volume down to highlight wipe cache partition and then Power to select it. Highlight yes and then Power again to select. When it’s done press Power to select Reboot system now.
- If you have a MicroSD card in your S7 Edge, then try turning the phone and take the MicroSD card out, then test to see if the problem persists.
- You could also try turning the phone off and removing the SIM card, then turn it back on and test to see if the problem is gone. If that works, then call your carrier and ask for a new SIM card.
- Still no luck? Back up all your precious files and try a factory reset. Go to Settings > Backup and reset > Factory data reset. When setting the phone up again, don’t restore your backup, test to see if the problem is gone first.
- If you still have an issue after a factory reset, then it’s time to contact your carrier, retailer, or Samsung and get a repair or replacement handset.
