One of the selling points of the Samsung Galaxy S6 Edge (#Samsung #GalaxyS6Edge) is its screen (or screens) but what if you see a black line or a small white circle on it that won’t go away no matter what you do? A phone as expensive as it is has to be perfect every single time but that, too, is not a guarantee.
I addressed some screen related issues in this post so read on to know more about them and what to do in case you’ll encounter one in the future.

Here are the problems I tackled in this post…
- Black line on top of the screen
- Screen sensitivity setting not available
- Small white circle on the screen
- Touchscreen not working after it got wet with juice
- Lock & Home button don’t work all the time after liquid damage
- Screen orientation is wrong
Problem: For the past 2 months have been having this issue where I will click on the home button and swipe to unlock and at the very top it will show a back line in an arch for maybe 1 to 2 seconds but will go away after the home screen is up. Just have not seen anything on the Internet about this. Would like to fix it… I have not dropped or banged my S6 Edge ever. No clue where this came from and software update hasn’t fixed it. I have been to Samsung and they checked it out and said it was a software glitch. Would like to get it fixed soon it’s a little annoying.
Suggestion: If this issue has been happening since day 1, then it’s probably more of a hardware problem than just a software glitch. This problem is not common, in fact, you are the first to contact us about it and we’ve done a thorough search on the web to see if there are others who may have the same issue as you and we found nothing.
But assuming Samsung technicians were telling the truth and were not just trying to dismiss the problem without resolution, then future firmware updates may fix it and there’s one thing you really have to try to see if it can make a difference–master reset.
- Turn off your Samsung Galaxy S6 Edge.
- Press and hold the Volume Up, Home and Power keys together.
- When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
- Wait until the Android Recovery Screen appears after about 30 seconds.
- Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
- Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
- After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
If the problem remained after the reset, then it could be a hardware problem.
Question: I just bought my Samsung Galaxy S6 Edge yesterday and would like to increase the screen sensitivity as well as the Edge bar. I read your comments, so realize there is no fix for the bar, but under Settings / Display, there is no sensitivity option. I have 5 choices (font, screen timeout, smart stay, screen mode and daydream). I have look at each of these and do not see a sensitivity option. Any ideas? Thanks, Kelley.
Answer: Hello Kelley! The Samsung Galaxy S6 Edge already has an increased screen sensitivity so Samsung didn’t bother to include the setting for it. In other words, there’s no way you can manipulate the sensitivity of your phone unlike the previous models of Galaxy devices.
Problem: Hi, I’ve been reading your website and I have an issue that i would like to ask. I have recently bought a Samsung Galaxy S6 Edge (3 weeks ago) and lately i have noticed that in the middle of the screen, there is a small white circle which is barely visible but it doesn’t look nice. I have 2 years warranty. Can you please tell me where does it come from and if I should ask to be replaced? Thanks. — Etienne
Troubleshooting: Hi Etienne. Actually you need to find out if it’s a firmware problem or a hardware (specifically the screen) issue and I know just one way to do that–take a screenshot and view the picture on your computer or any other device.
If that small white circle is visible, it’s a firmware problem, otherwise, it’s hardware. Aside from the screenshot, you can also try to change the screen orientation from portrait to landscape and if the white circle remains on that very same spot no matter what the orientation is, then it’s hardware. In this case, you need to have it replaced, otherwise, you need to try to master reset the phone and if the problem remains, have it replaced.
Problem: Good evening. I’ll start from begin with my touch screen issue. I’ve put my phone next to my bed. but apparently some juice felt over my phone in mid-night. the next morning i woke up and the whole table was wet of the juice. i tried to clean the shit off and put the phone in a bag of rice. it didn’t work, so i thought i put my phone in warm water (not cooked) to get off the sticky juice on my screen. but still has the same effect. the phone works normally except the touchscreen. what should i do? replace the display or is there a alternative. Kind regards, M. Hama.
Troubleshooting: Alcohol will get rid of that sticky juice residue but since you already tried cleaning the screen up and the problem remained, then it’s time you had it checked by a technician who can further do tests. There’s a chance juice has found it’s way into the phone and messed up with the digitizer that’s why the touchscreen isn’t functioning. For hardware issues, there’s not much we can do about it.
Problem: Embarrassingly tears got in to the lock button of my phone. It froze until the battery died. Next day it works for about a half hour, then the lock button seemed to work about half the time to turn the screen on and when it was on, green lines appeared on about 3/4 of the screen. I took the motherboard out and there was corrosion, took it to a local repair shop for some kind of bath (forgot name). It works better now but still flaws, half brightness or less 3/4 of the screen flickers (doesn’t when brightness is all the way up, lock screen and home button don’t turn screen on right away (usually 2 or 3 times, sometimes will shut off). I guess I need advice on whether i need a new lcd / digitizer a new lock button ribbon (which also had corrosion) or if the motherboard is bad? thank you! — Matt
Suggestion: Hello Matt. When it comes to liquid damage, we won’t know the extent of the damage until we did some tests. You seem to be techie enough to teardown your phone without damaging it so I know you understand if we told you there’s no way for us to know what the problem with your phone is. But based on your description, if the lock button doesn’t work all the time, then it has an issue. Corrosion might still be the cause resulting to improper contact. But the thing is, if you try to open the lock button, it’s good as damaged, so there’s no better way to test it except replace it. As to the flickering screen, it will take a lot of tests to be able to conclude it’s a motherboard issue. Please see a technician who can spend time with you testing the different components.
Problem: I have had my phone over 6 months now. Recently, I have noticed that when I rotate my screen for random things (like looking at websites or you tube), it rotates the wrong way, so basically it’s upside down. It doesn’t do this all the time, but more times than not. It used to be fine. I haven’t downloaded any new apps, it just started doing this out of the blue. I tried looking for a solution online, but I couldn’t find anything. Please help. Thank you.
Troubleshooting: It’s difficult to pinpoint what the problem is if the phone doesn’t show any pattern, so, try to isolate the problem first by booting your phone in safe mode:
- Turn off your Galaxy S6 Edge.
- Press and hold the Power key.
- When ‘Samsung Galaxy S6 Edge’ appears, immediately release the Power key and then press and hold the Volume Down button.
- Continue holding the Volume Down button until the phone finishes the restart.
- When you see Safe Mode on the lower left corner of the screen, release the button.
Continue using the phone while in safe mode to know if the problem still happens and if so, try wiping the cache partition first and then try the master reset if it fails.
Wipe Cache Partition
- Turn off the device.
- Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
- When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
- When the Android System Recovery screen appears, release the Volume Up and Home keys.
- Press the Volume Down key to highlight ‘wipe cache partition.’
- Press the Power key to select.
- When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
