Proximity Sensor Issue?

When i place a call and put the phone to my ear and then pull back away the screen does not "wake". It stays de-activated, no matter what i do. Eventually the only thing to do is to hold the power button down long enough for the phone to reboot.
Stock ROM, no root.
Thanks for any help anyone can offer.

WTF
I tested by laying the phone flat on a surface, placed a call, and then put my hand over the proximity sensor. The screen turned black as it should. When I removed my hand it did not come back on. Again, the only solution is to reboot the phone. So, the proximity sensor is not working correctly. Is this a known issue and is there a way to fix?

BUMP!
I'm in the self test module and am running the "sensors" test. I'm not sure when this ends if it ends at all or what values that proximity sensor field should have.
Anybody? Bueller?

Apparently Q&A isn't the place to post this? This is dissapointing coming from the E4GT forums which were super responsive.

Cool yer jets. It's only been a few hours. What ROM? Rooted? Any other mods that might affect it?

LOL
I said no root stock ROM
Anyway, I turned off the proximity sensor, verified that it was off, then turned it back on. It works now. Bizarre.
Sorry to get pissy.

NOT FIXED
So after a reboot the proximity sensor does not work on calls again. I turned it off and then back on and still no luck. I didn't actually make a call, but obviously I shouldn't have to do this every time i reboot the phone, so clearly there is an issue. It appears to be software since I got it to work once.
Any ideas? Thanks.

After insalling a new screen my phone acted the same. I opened it up again and found a tiny piece of plastic form the old screen inside the proximity sensor hole.
I know your problem is not this, just wanted to share

hmmm interesting. I think this is likely a software issue on mine. it would be dumb to have to return it since i'm confident there's a way to fix it.

That solution wasn't very good aha, what I would suggest you root your phone without tripping the flash counter and install a custom rom to see if the issue still exists, if yes you should return the phone.

thanks well it's brand new and it may be hardware related so i'd rather just get a fresh device then sweat dealing with root yet. this is why i waited to root it. I appreciate your effort though .

Plus I don't think just rooting it is a sound fix strategy.
Nobody has anything on this huh?
BTW, Wirefly sucks...

Have you already done a master reset?

Butt Dialing Sister

Purchase an OP3 for my sister when they were 1st released. For some reason, her phone frequently butt calls me. I can never get a straight answer from her what she is doing when it happens, but today she said her phone was just sitting in her purse. Can anybody think of what feature/setting/option she may have toggled on or off that is causing this? I believe she is on unrooted stock 3.2.7. Thanks

Turn on the pocket mode and probably ask her to put a password on her phone.

To top it off, I think she has "Proximity Wake" also turned on. That will really cause issues in a purse...LOL

Haha yes. Its a useful feature if your phone is usually on a desk otherwise it can be pretty annoying feature.
Sent from my OnePlus3 using XDA Labs

I just ran a styrofoam cup over my phone with proximity wake enabled and it woke up my phone, so depending on if it's stored during commuting around like pocket or purse, it's quite likely that's the culprit. Other user's suggestions would be a good call

Well, I tried the solutions recommended here but they did not work.
To recap,
1. Turned on Pocket Mode
2. Turned off Proximity Wake
These two setting did not solve problem. Any other suggestions to keep OP3 from Butt dialing?

I don't usually have an issue but I found that not sliding my finger onto the sensor makes it work much more reliably. I just try and tap centered on the sensor and it works almost every time.

So back for repairs then. Or You can try Factory reset.

I had the same issue, someone in the forum suggested enroll the same finger multiple times for more data, the sensor is pretty small and easily stops working due to sweat and oil, keep the back of your phone pristine at all times, that might help a little, you will run into less issues this way.
Although I gave in and started using Pin authorization recently.

This happens in my case too....at every 15-20min. i have to clean the fingerprint area with a microfiber cloth and then it works only for 2-3 times.....this is really annoying...i have tried multiple times registering my finger...but doesn't seems to work.
Tried factory reset but still the problem persists.

Same here! All of a sudden my screen goes crazy, as if three fingers are touching the screen at the same time. Quick fix: restart the phone.
I waited reporting the issue to see if more people have it, or it is just my phone.
Hmmm... now that I think about it, I better wait rooting the phone and tripping Knox in case of fixing this problem under warranty...

Same problem on my phone. I have a glass screen protector, I thought maybe it's because of the screen protector. Sometimes locking and unlocking the phone also solves it for me.

I also have a glass screen protector, but I experienced the problem also without protection, since I applied the screen protector a day later.
Locking and unlocking the phone seems to "solve" it as well indeed.
Hmmm... seems we got an issue here, Samsung!
I have also addressed this topic to the online shop I bought the phone.

Ghost touches did happen to me during the first three or four days after purchase. Now however, they are completely gone.

I've had this happen to me two times in three days on two different A70's (one time on each phone). Most likely software issue.

yes me too, i can't even type fast bcs it will trigger a ghost touch between the two alphabets i'm trying to type, feels like an old man for typing slowly lol

Give it a few days. Restart your device every other day and press the malfunctioning spots on the display a little harder. It worked for me.

I must say the ghost touches are much less after using the phone for a while. I also just tried your tip, and hope it will be completely gone now!

A70 touch problem solved
guys i think my problem got solved do this thing*
1) switch off the phone completely*
2) press volume up key plus power key until Samsung logo appears you'll get into boot loader mode*
3) to move up an down use volume keys to select options press power key now you have to select WIPE CACHES partition*
4) then select run graphics test*
5)then do system reboot
give this a try it worked for me an let me know if it's works for you or not.

I'm also having the same issue. Tried the 1st solution. (https://forum.xda-developers.com/galaxy-a70/help/ghost-touch-t3927693/post79538651#post79538651). However my phone didnt restart automatically so I restarted manually. I'll update the results. Thanks a lot.

Got a software update this morning which seems to have fixed it. At least I got to type this comment faster :laugh:

guys, I don't know if it's a "ghost touch", but if I get my finger really close to the display it acts as if I touched it on that spot - but I don't feel like I've touched the screen at all... is it really sensitive or is this the ghost touch issue?

Question Prevent accidental unlock - !of course! not working!

Unfortunately this !!ANCIENT!! Samsung bug appears also on A72 now ..... Does it work at all on your A72? Any ideas per the issue?

Do you mean the setting in display - accidental touch protection?
This will only work when it's very dark ... like in a pocket.
Best to use a secure unlock method such as password, pin or biometric.

I also experience this issue. And actually an that specific scenario. Wvery time I put my phone in my pocket. It turns on and the first thing that press is the widgets in the lockscreen. I notice when my leg is really hot. I gotta say it's annoying
