[Q] Removing stains on home button? - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi guys, recently I just notice that there is this small stain on my home button and I can't seem to clean it off no matter what. Although the stain is not very obvious and only visible when there is light shinning/reflecting at it, but I still sometimes find it annoying. Any ideas what can I do to remove the stain without damaging the Note 4 fingerprint scanner?

Smudging/Grease near Home button - 4 days old

I just got my S4 and it appears there is smudging around the home button, where my thumb presses it. I don't use a screen protector but this has nothing to do with that. It is like a grease spot that doesn't come off. Anyone have this before? Should I return it?

Stumped! On 3rd g900t digitizer-Cant get rid of issue (recent menu/left touch) HELP!

I am on my 3rd g900t digitizer-Cant get rid of issue
what happens is: the menu for when you hit the left touch or "recent" button keeps coming up without me touching it like every 45 or so seconds, only when im touching the glass.
Something is telling my phone that im hitting that left button when i am clearly not. Its *not the digitizer itself because ive tried 3..
ive replaced the charger port assembly once as well.
A: does anyone know of a way i can disable the left touch button on the s5 ? (More specifically-just the functionality,not the light)
fyi this did start happening when i replaced the digitizer, the actual plastic silver case & the charger port. Maybe its the case that's doing it? Anyone ever heard of anything like this? Its driving me nuts, i cant use my phone, sick of buying replacement parts!
Please please help me on this brothers...
IS there anyone with any idea on how to disable the left touch button on an S5????
What if i simply Snipped the button after lifting the digitizer?? would that work?

Replacing front plastic panel color with Home button = not working Fingerprint scanne

Hello all! Sadly, some time ago I have dropped my S5 onto a concrete curb & my screen got through that 2 cracks on the plastic digitizer protector & has missing a bit of the glass at the top & has a hole through the plastic panel under the bottom which worries me about it still being waterproof... I wanted to get the plastic panel replaced (which is relatively cheap since the digitizer isn't broken) together with changing it's color from white to black together with the Home button (I got the white S5, which I now regret getting...) but a friend of mine told me that when the Home button would be changed, I would loose the fingerprint scanner function, which worries me a bit [emoji52] Can someone confirm if this is true or not? Because if it is, then I gonna have to stay with the white color, which I don't like that much now [emoji17]
Someone?

S7 edge home button paint peeling?

Anyone else with this problem? I had what I thought was a chip in the middle of my home button which I thought was strange as I am very very careful with my phones and did not drop it, anyway I let it slide and a few weeks later now a long strip at the button of the home button peeled off as I was applying a screen protector WTF. I bought it straight from sammy so hopefully if I take it back to the store they may be able to replace the button under warranty. Has this happened for anyone else?
Mine also has a visible scratch on it. I doubt they will replace the button because I heard the entire display has to be changed for the button alone.
hello,
I've got the same problem. Do you guys think it will work if paint gone? It is just paint? I don't really care how it looks like- if it works

LG V35 double tap doesn't unlock screen, always on display doesn't work too - Help!

Hey guys, just got LG V35 updated it to android Pie, everything seemed fine, but i can't normally unlock phone. On main screen i can double tap and it locks, however double tapping again, doesn't unlock phone, as if screen froze. Also fingerprint button doesn't work either, i mean i need to press it twice slowly and only then screen turns on and shows lock screen, always on display also doesn't work. After simple restart those features work, but after a minute, same thing happening again. Also noticed, that if someone calls, screen is also unresponsive. Got phone couple days ago. Any solution ?

i had the same issue when i got mine. i think the screen protector i installed was the issue-it only had adhesive around the the edge and started to come off. i returned that one and replaced it with another make and haven't had the "knock on/off" issue since. good luck

I agree with tomdi1999 and also have used the adhesive around the edge screen protector but they interfered with screen touch sensitivity, it is as if having a couple of fingers touching the screen permanently while trying to double tap or unlock the phone via power button. If you have any glass screen protector, try removing the screen protector and double tap again to see if it fixes the issue. If you are not wanting to remove the screen protector first and want to do some troubleshooting, try run touch screen test via the hidden menu (assuming your v35 is AT&T version) by dialing *#546368#*350# (Be warned that some options in this menu can really mess up your phone so don't go around messing with options in this menu randomly) in the phone dialer. In hidden menu select Device Test -> SAAT -> Service Menu - Manual Test -> Touch Draw Test. If, with screen protector on you are having trouble doing this test, remove the screen protector, clean the screen, and do the test again. If you still have trouble with touch screen it is probably a hardware problem or could be software problem but unlikely though. Also, place a test call to someone and slowly place your hand to cover the ear piece and proximity sensor area to see if screen goes dark. This is to check if your proximity sensor is working properly because if it is not then it could be the reason that double tap to wake is not working, although it doesn't explain why your power button is responding slowly, that points toward the phone processor being busy due to ghost touches such as due to bad screen protector or just a faulty power button (but what are the chances of having a faulty power button and double tap to wake going bad at the same time lol?).
I remember that years back on LG G4 double tap function would stop working if you had the screen replaced or sent in the phone to LG for repairs such as repair for notorious bootloop issues and it turned out that there was a small rubber piece that went around the proximity sensor that people were forgetting to put back when replacing screen or doing other repairs which basically broke the proximity sensor. Proximity sensor is suppose to disable screen wake up due to accidental double taps such as when phone is in pocket but if proximity sensor is malfunctioning it will not let phone wake even when you double tap to wake it.
If you figure out what was wrong and/or fixed your issue, please do post back so it can help others. Thanks.
Edit: If you are looking for a good screen protector try Skinomi or Armor Suit wet screen protectors. They are not glass and are a pain to put on but once you install them and let them dry, they are awesome.
It helped me thanks a million!
wouldn't think ever it was the screen protector, thought one of my apps...
I've removed it and it was back to normal.
thanks again
