Fingerprint Sensor after Screen Replacement - Samsung Galaxy S7 Edge Questions and Answers

Hey,
I got the following problem:
I replaced the screen on my S7 edge by myself, using a Screen / Frame assembly including a new home button.
Now, when I try to setup a fingerprint, a window pops up saying that there was an error with the fingerprint sensor. I read that the sensor is synced with the board, is that true? And if thats the case, is there an option to resync my new fingerprint sensor to the board?
Many thanks, Sebs :good:

Air Gesture/Proximity sensor not working

Hey everyone,
I'm kinda new to this section of the forum, I've had the sprint galaxy s3 and been in that forum but,I just recently bought a unlocked at&t galaxy s4 on ebay a few weeks ago for a cheap price, because the screen was cracked, but the lcd and digitizer was intact.All of my features was working air gesture the whole nine even with the cracked screen.I bought a new screen online and paid someone who fix screens 20$ to fix my screen.All is working and the screen is very responsive and perfect,but it seems that my air gesture sensor/proximity sensor isnt working and the RGB light sensor seems like its blocked by something because it lights up but you can only see a partial part of the light like its covered up or being blocked.Every time i go into stock browser i can see the hand icon showing up but its only responding to my tilt to scroll function.My hand movement isn't working at all or the other air gesture features.I have everything checked in the sub-menu and also used the *#0*# code.The guy said he will fix it for me but i wanted to know was the proximity sensor and air gesture sensor connected because I've seen the proximity sensor flex cable on ebay for like 6$ so maybe he might have damaged the sensor flex cable when replacing the screen.

Disable proximity sensor entirely

Hello guys,
I cracked the screen of my Nexus 4 and ordered a replacement screen + digitizer from ebay. After waiting 2 months and putting the phone together, I realised the proximity sensor isn't working. I followed some guides and realised I've lost the little bit of rubber that goes in between. Is there something else I can use, or even better, can I disable the proximity sensor entirely as it's not important to me at all?
Thanks
Yes. There is Xposed Framework plugin which allows you to disable it. I use it and it works good. The name of the app is Disable Proximity Sensor.

Problems after replacing screen, LCD and frame

I have replaced the screen, LCD and frame on my VS980 due to dead sections of the screen. There were no problems swapping everything over to the new frame. The phone seemed to be working perfectly until I went into a dark room. When I am in a room with little to no light knock on does not work and if I press the power button the screen times out while I am swiping the home screen. Which component will cause this problem? I double checked each piece before reassembly and everything appeared to be properly installed.
Have you tried the motion sensor calibration? For me i press the power and volume down button quickly and it unlocks. Have you update the touch firmware?
I did the motion sensor calibration and it didn't help. the dialer codes I have found for the vs980 don't get me into the service menu.
I dont know for sure but i think its the hardware problem as in replacing the new LCD and all, but ya that be expensive to buy new ones just after buying a new one. If it still have warranty maybe replacing it perhaps. If the service menu dont work, i dunno.
Your proximity sensor may not be plugged in all the way.
How does the phone work while making a call?
Test it first. If the screen stays on during a call while the phone is held to your face, open it back up and double check all connections.
Unplug and replug the screen, digitizer connections, selfie cam and proxy sensor connections then test again.
The proximity sensor which is top left when looking at the front display. Smush and/or rub with your finger, then try to unlock again. I have to do this frequently.

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
