Here's what is going on...
My Galaxy S I9000 (Bell Canada) was water damaged, after being dried for many days it turned on, but the battery almost immediately drained. I left the phone and forgot about it. Bought a new cheap phone without a SIM.
More recently I got a new battery for it and it turned on and was working great, staying charged and everything. When I went to the service provider to get a new SIM for it, we powered down the phone, pulled the battery and SIM card and put the new SIM in followed by the battery. Afterwards the phone would not power on, but the two face buttons on either side of the 'Home' button lit up and would react to touch. I tried removing the battery and SIM a few times and would get the same result.
After bringing my phone home and leaving it with the battery out for a few days, I thought I would try it again. It powered up again as if nothing was wrong. To test it again, I pulled the battery and SIM, replaced them, and my black screen/won't turn on problem returned.
Every so often it will power on and be useable. It is recognized by Kies, I've flashed it to firmware 2.3.4.
I'm looking for any helpful suggestions for what might solve my problem. I'm wondering if it's a hardware problem and short of isolating the part of the phone that is faulty and replacing it, the phone is toast.
Thanks for your time, and I apologize for the length of my post.
My friend has dropped the SGS into a pool before. Problem was fix after buying a new battery.
Either: Damaged screen + Contact. Or the reaction with water and the battery. hydrogen gas prevents screen from connecting to main-board.
It still turns on occasionally, and when it powers up, it's as if nothing is wrong. Screen works, displays everything fine, colour is crisp, screen reacts to touch. The big problem is it won't turn on all the time. Would what you said still explain this?

The only thing I know (assuming the screen or motherboard is 100% functioning) is hydrogen gas being present. You might know TV remote with old battery casually respond to presses. After cleaning contacts it should work again.
I disassembled the phone and cleaned all the contacts on the main board with rubbing alcohol, I did not do anything to the screen though. Should I try taking it apart again and breaking it down further? (ie. separate the screen?)

No, I am starting to think it's a hardware fault if that didn't work
Hi folks,
I recently ordered what appeared to be original huawei p9 replacement screen together with metal frame and replaced broken screen. Phone now boots normally, I can also boot to fastboot and recovery, but unfortunately phone doesn't have ADB debugging and OEM unlock turned on.
When phone boots normally, I can get only to the lock screen of "Smart view" or "cover view", so I cant unlock phone or anything else. I tried also with mouse via OTG, no luck...
Anyone have some other idea that I can try? If i could enter settings to turn off cover screen all would be good
Cover is usually detected by magnet.
Could you try to play with some magnet or cover from another phone to get it unlocked for once.
Maybe, making an incoming call could help to unlock.
Once you get in (?), go to Settings, Smart Assistance and permanently switch off Smart Cover - it's by default on, most people don't have the cover and IMO it helps draining the battery

I tried the magnet, no luck. Also incoming call is impossible since I get no SIM pin input prompt at startup... Any other ideas?

You can move SIM to another phone and disable PIN, then put it back to Huawei.
Not sure would it help, you may have hardware problem with the replacement parts or work
To clarify this issue - the problem was in charging board, so changing it solved the problem. Other solution (if everything else works) is to remove charging board, boot the phone and disable smart cover in settings & then inserting charging board back.
Hello,
My Huawei P20 Pro got stucked in a mode where displays black screen and only for about 40% of the screen, in the right it displays clock, date and weather. I can be called, the phone is charging but that's all. I had about ~70% battery when this happened. Reboot doesn't resolve the issue.
Any idea?
Thank you!

This sounds as if your P20 Pro is stuck in the mode for a closed flip case with a window (see https://i.ytimg.com/vi/G7sU3yGpRF8/maxresdefault.jpg).
That mode is normally triggered by a magnet located in the lid of the flip cover. Do you maybe happen to have a magnet too close to your P20 Pro?
Thanks
That was the issue. I just took off the case (which is not with flip) but it has a magnet for car. Thank you for your reply.

hi, I have this issue. no flip case... n I can't into settings to turn off Smart Cover any ideas?
Anyone managed to fix this? I have the same issue. Tried everything, safe mode, recovery, restarting... I do not want to lose my data, is there a way that I can login and back up my data and then factory reset it? I cannot login because the screen is irresponsive and cant insert the pin for the screenlock, otherwise the screen itself works.
Dissconnect the Charging board

remove gently the back glass without damaging the finger print sensor flex and disconnect the main flex cable which goes from the second board to the main board, and start the phone without connecting the man flex, you will be able to go to settings and turn the slim cover option off
i have done almost everything talked about above on this phone for a week now but the black screen with date and battery percentage cant go off and the phone cant open anything else. its where it stops. what do i do . guys i need help i feel frustrated
Did anyone resolve this issue?I have same problem.however my screen did come back for 10-15 sec back and i manage to do hard reset but now i am stuck on black screen
Maybe too late, I was changing my battery already, then same thing happened to my p20 pro. I tried to use magnets to try unlock to no avail. Anyway read that the hall sensor is just at the upper left of the fingerptint sensor. After replacing the battery, turned it on, smart lock still active. Flipped it backwards, unscrewed the bottom right screws and gave it a few tap or knocks by hand an voila, screen is back to normal. I cant pinpoint the problem was, but thats how i fixed mine

I have the same problem on Huawei p40 Pro, I tray hard reset but nothing help. Anyone have solution for that problem?
Is this problem with software? Need to update or downgrade?
Hello
I have purchased a p30 pro recently. Yesterday, while using phone, suddenly the screen colors got washed out, then after some minutes the screen went full black. I believe touch is working, just the screen sometimes draw some subtle vertical lines and no image appears.
I'm not much concerned if the phone works or not in the future, but i have very important files in the phone that i need to retrieve and i believe if i send the phone to a service center it will be reseted.
Any suggestions of what i should do?
I've tried:
- Pressing the power button 20 seconds while phone is connected to tv whith an usb-c - hdmi adaptor. Huawei logo appears on tv but after that screen flickers with black. If i was able to have the pin screen there would've been great as could install an app to send fles to cloud after.
- Tried with the PC suite HiSuite, but since mobile is locked with pin, it cannot connect to do backup.
- Tried to insert the pin in "blind" by touching screen
Would appreciate if someone could help. Is there any way to enter the initial pin to have access to mobile, but without using screen?
Thanks
P.S. Phone didnt felt or anything, just subtedly washed on the faucet with just water as it was bit dirty (like 10 hours previous to failture). Wasnt submerged either. Will try to put it on a rice bowl eventually, but an IP68 phone (Pro) i find strange, i have done that several times on my old S8 and never had an issue.
Phones are NOT waterproof. Have seen several liquid damaged iPhones and Galaxy phones. Most likely the phone is liquid damaged. Second likelihood is damaged display. Rice will make it worse. You’ll need someone, a mobile phone repair technician, to open it up as soon as possible and remove the corrosion with IPA or an ultrasonic cleaner. The longer you wait, the worse the corrosive damage becomes. Look for a shop that's competent enough to remove the rear glass without cracking it. Franchises are generally less reliable.
You can use HiSuite to retrieve files or even preview the contents of ur display , thing is you have to find a way to press the accept button for the usb authorization when asked from the phone.
EDIT: Just saw you used the method but your phone is locked with a pin so i would suggest to try the blind method to unlock the phone.
Solved, thank you all
Was able to unlock and backup everything, was lucky
Please help let me know if screen activating in pocket is a bug or if this is intended design (i.e., design flaw)?
Now that it's summer my leg can get a little sweaty. But my phone in pocket triggers off my leg due to the moisture! Then the phone will randomly edit various things as the phone bounces around in my pocket.
WTF, why won't the phone just detect the darkness and know it's in my F*ING pocket! My S9+ was really good about this, it knew when it was in the pocket and ignored my sweaty leg.
But with this retarded S21 Ultra, it doesn't seem to know when it's in your pocket. I've already lost several important appointments and tasks (my calendar and task lists widgets are on the main screen) because the dumb phone let my *LEG* edit/destroy/delete the important tasks and calendar entries.
I'm holding out hope that maybe this is not how the phone is designed to work, maybe I can fix it by doing a factory reset. But I recall other posts complaining about how the phone is too retarded to detect being in the pocket when it comes to the Always On Display (AOD) and just keeps the display on while in the pocket too. So maybe it's a fatal design flaw of the phone, where if it is hot outside and you have moisture on your leg, your phone will think your leg is typing and just randomly change things.
Please help me understand whether this is a fatal design flaw or just some bug or what!?
please disable the option to activate the phone/unlock phone via sensory detection
i believe you need to deactivate that first from the smart lock - on body detection
and then also go in advanced features, motions and gestures and deactivate lift to wake

Used to happen to me too. Ofter i would only realise phone was awake and messing around by the beeping sounds of the dialer going off in the pocket, or the increasing temperature of the phone against my thigh - screen on for God knows how long.
Pocket detection is dubious at best - doesn't work consistently. All this happened despite it being set to "on"
Turning off double-tap-to-wake screen helped me.
Now the phone only wakes up for calls and will show lockscreen only if I hit the power button (side key) - I have never used AOD, so screen stays off no matter how hard you tap away at the screen.
Unfortunaltely this puts a lot of mechanical wear on the side key (waking up the phone to unlock)
TO solve this, I have set my Fingerprint scanner "always on" enabled, so if i want to unlock phone without wearing out the side key, I just hit the screen with my thumb where i know the fingerprint scanner is, and it takes me to the home screen without showing the lock screen. I've developed muscle memory now and can hit the correct spot on the screen 90% of the time without the fingerprint icon displayed on screen. No perceptible differnence in battery life as opposed to keeping fingerprint scanner always on disabled.
This has worked for me. Maybe you can try it out and see if it solves your issue.

I dont think that would put any mechanical stress on the power key.
Phones are tested for upto millions of press of buttons which you woudnt be able to achieve in your lifetime .
I have my aod on always , and double tap to wake on always .
Best possible way to avoid accidental wakeup is to insert your phone with screen facing away from the body i.e towards the fabric of pants/jeans/lower

Yes, lift to wake was already disabled while the problem happens. The phone still wakes from "taps" caused by the leg.
I want to clarify, the problem is not caused by the phone unlocking or locking.
The problem is because the phone is not ignoring screen taps when in the pocket. It thinks I'm double-tapping to wake the phone.
I'd like to keep enabled the smart lock on body detection, and keep enabled the double-tap to wake. I can see how keeping the phone locked would help, but the root problem is still there - the phone wakes up even though it is inside the pocket.
Keeping the phone locked would just transform this to a new problem - how do I prevent my phone from waking up in my pocket and wasting energy while my leg enters various unlock codes by itself.

Yes, the S21 Ultra refers to this as "Accidental Touch Protection." The flavor text explains "Protect your phone from accidental touches when it's in a dark place, such as a pocket or bag."
Accidental Touch Protection has been turned on when I had the problems.
Does anyone know why Accidental Touch Protection is not working, even though it's turned on?
The setting is found under Settings - Display (scroll down, 4th from the bottom).
Keep the back of the phone towards your leg, problem solved.

Yup, you may be right. Ideally they should last a lifetime. But all mechanical parts are prone to failure. Same thing holds true with charging ports - they shouldn't fail, but often do. Doesn't happen to everyone, but it's something to keep in mind.
I've had my HTC power key fail on me due to constant use over 2 years, and ever since then I've stuck to using the screen for wake-up. Needn't happen to everyone, but once bitten, twice shy, right?
The screen facing outwards is a good idea and it was the first solution that came to mind when I was having accidental wake-up issues. Tried it for a few days but stopped using it because it's awkward for me (camera bump irritates thigh) and it was un-intuitive to take out the phone, then turn it around in the hand to start using it. I just wasn't comfortable using it that way.
Like I said, this set-up works best for me, everyone might have their own way of doing things
All I know is that with this set-up, I don't have any more accidental wake-ups while the phone is in the pocket. That was the main requirement.

If you'd like to keep the tap to wake feature on, then the best solution for now appears to be what @aj7400 and @blackhawk have suggested - Keep the phone screen facing away from the thigh.
The screen of my phone frequently turns on when it is in my pocket and the phone starts performing some tasks like playing music.
Does anyone of you experience the same problem ? Is there any method to prevent accidental touches when the phone is locked ?
Edit: sorry I didn't notice this thread, so I created another one for the same problem. I'll try some of the solutions you proposed guys, hopefully it will fix the problem.
Was there any pattern to when Samsung's "accidental touch protection" failed to keep the phone screen inactive?
I'm trying to find out if there is anything going on that might affect the accidental touch protection. Normally, accidental touch protection keeps the phone screen off when the phone is in your pocket, to protect against unwanted touches or "butt dialing."
But in my case, my leg was a little sweaty and the phone screen activated and deleted some of my important info.
Has anyone else seen anything in terms of a pattern when your accidental touch protection fails to protect against accidental touches?
Maybe you had see-through pants with white pockets with direct sunlight glistening off your sweaty thighs?

Nope. Happened to me in Dark blue denims as well as black trousers.
It's not consistent. Works most of the time but fails every once in a while.
For me, usually I become aware of it when i hear the dialer beeps (somehow the screen taps end up on the emergency call dialer screen) go to town.
Funnily enough, I turned the feature off and was roaming around the city for more than 2 hours. No accidental wake-ups at all. This is even after I have temporarily restored double tap to wake screen. Need to watch this for a few more days and if i don't get any more ghost wake-ups, i'm keeping it turned off.

Turned off Accidental Touch Protection
Have you also tried just initiating LOCKDOWN MODE via the power button before a run?
I'm guessing that your leg and the sweat and the fabric combine to give the electric feel of a skin's surface that activates the phone?
You could also use a Bixby Routine to disable double-tap to wake?

Let us know your conclusion...I went the EXACT ane route (before finding this post): disable ATP and created a routine button to disable double tap to wake when I take the phone out for a walk.
Seems to be working, but it's another source of frustration as my previous Huawei mate 20 pro had the ATP feature but never started playing muzak in my pocket.
Samsung...good hardware plagued by half-baked software.

The Huawei mate 20 has much more major issues than our SK allies flagship phones do in more ways than one
I don't have these issues on the 10+ unless a put the phone facing my leg on the display side.
You should have a good case that has side protectors slightly higher than the display plus end display protection in the case ie Zizo Bolt case. Otherwise a face plant can easily destroy the display. These phones need case protection... before they kiss the concrete.
This also help stop accidental touches both when on and off. It makes the phone easier to hold and use as well.
Face the display away from your body. That should be more than enough...
If it's really still a problem limit display timeout to 1 minute.
Use only the power button or volume control buttons to activate the phone.
-or-
Use a case clip holster.

Well, in conclusion I can only say that the setup is working... Haven't changed anything since then and no accidental pocket mishaps yet. ATP and Double tap to wake are still off.
BTW, your idea of a Bixby routine trigger to disable double tap when heading out to walk is quite neat
