Samsung S4 S-sview/ Black Lockscreen flickering Issue (Fixed) - Galaxy S 4 General

Hi Guys,
I was really frustrated with my Samsung Galaxy S4 I9500 as it was continuously flickering the black lockscreen (with Time date) whenever I was on data usage. There were many users who have reported the same for S4 worldwide as well as Note. but none of them confirmed to give any valid resolution to the same.

There is also a few videos of the same issue.
The issue is obviously with the magnetometer placed near the Volume Down Key and I tried almost all suggestions over google. The one that finally worked is obviously not from my brain !! But this post is for people not to get misguided by other fixes and to document a valid resolution to the issue.
So no credits to me.
WHAT I HAVE TRIED:
Disabling Sview/ Proximity Sensor/ Air View options from settings. -No Help
Changing ROM doesn't show the Black screen but somehow the sceen gets locked randomly.
Screen/ Motherboard replacement - No Help
Fix:
VERY Simple..
Open your back cover. On the back side, there is a screw just near the Volume Down Button (named L1). Seems this screw gets magnetized somehow in the viscinity of the magnetometer.
Try the one that works for you:-
1. Open the screw, then insert it back but keep it loose. Dont make it too tight. Test and see if it works for you.
2. If the above doesnt work, open the screw completely and dont insert it back. In its place you can try to insert a brass screw if you have or else keep it like that. Test if this works.
3. Still not working? Open all the screws, open the body. Put back the body, insert all the screws just not the L1 one. Dont make the other ones too tight. Test now.
Trust me I have tried everything, none worked. I didnt want to go to Samsung Service centre, so thats your wish. But some users reported they were of no help. Mine worked flawlessly in the last step and seems the issue is gone. So gove it a try and press thanks if I have helped you.

[Q] VEGAn Observations/Questions

Naturally I bought a g Tablet Saturday and Woot has them today for almost $100 less! Oh well. Big big big improvement from my old FlyTouch2 which was a great idea poorly executed.
Immediately flashed VEGAn with supplements etc. All working VERY well but a few questions/observations.
1) If I wanted to hook this up to a USB or Bluetooth modem (well, actually a BlackBerry) it looks like there is no setup for this? Yes, I know if I could find a way to make the BB broadcast WiFi but its corporate so that's a nonstarter.
2) When I hold down the power button, the menu that comes up it clipped off at the bottom. Is that normal?
3) Screen lock on Kindle software is not getting the accelerometer fix somehow. The trick was to put the thing in portrait UPSIDE DOWN and lock the screen. That caused it to lock it 180 degrees off. But then when it is locked you can go back to right side up (to me, right side up is with the buttons to the top). Of course, if you want to lock it another way you have to experiment.
4) Camera Fun shows camera upside down. No big deal -- again accelerometer I think.
5) Sometimes I am sure the machine is asleep and when I turn it on it is booting from the birds screen. Anyone else seeing this?
6) I don't understand the .nomedia thing although I've read a lot about it. I don't seem to get files erased, but nothing shows up in Video. But if I navigate to the folder (on /mnt/sdcard2) and play videos that's fine. Then later the files will show up in video. Whoops spoke to soon. Now they are gone. What's up with that?
7) My old tablet had GPS but without the external antenna it was worthless. But it still managed to find rough location with WiFi somehow. I assume by figuring out the geographic location of the IP. That doesn't seem to work on this machine. Yes Use Wireless networks is checked in Location and security.
8) What's with the little plastic cover? How hard is it to take out? I don't want a little rubber dingle rolling around inside.
8) In System Preferences, About Device | Status consistently crashes.
9) Does the audio jack support a headset or just headphones? Yeah I know -- I could just try it.
If it matters I'm using Launcher Pro.
Still and all the VEGAn ROM is superb. Compared to the FlyTouch this is super fast, the screen is a joy, and the battery life wonderful. And with the woot deal only about $80 more than a FlyTouch2.
Ok I'll answer some of my own questions:
5) I think this is the unresponsive power button problem. If you press and wait it seems ok. If you press, get impatient and press again you might reboot.
9) No, at least not with a Blackberry headset.
Most of these are answered on the forum somewhere, but I'll give it a shot..

I get this sometimes, too. It is a known issue, and there may be solutions out there... I just deal with it.

Known issue.
These aren't much help (maybe reassurance?)
1) Pretty sure it's wifi only. Have trawled the internet looking for a usb or bluetooth alternative because wifi hammers the phone battery
2) It happens on mine as well, so it's not just you
5) Same here - I just turn it off when not in use now
7) Only GPS functionality seems to come with the need for an external GPS unit
8) Think this is normal
(Re reading above, it looks like I'm negative re VEGAn - this is not the case. It is way better than what came standard and does everything I need it to do)
Yeah I like it too. Haven't tried the others, but very satisfied with Vegan.
Another observation: Long pressing the Menu button (hardware) brings up the keyboard. However, long pressing the menu button on the status bar does NOT have that behavior.
Clemsyns newest kernel will fix sleep issues. Also has some other great improvements too.
Buttons on status bar do not respond to long presses. Home doesn't bring up its usual long press of recent apps either. Funny, i Never even tried long press on status bar keys before now.

I have Pershoot's kernel. I'll try changing. I presume I shouldn't need to clear too many things in CWM after flashing a kernel. Maybe the Dalvik cache?

[Q] Touchy touch screen

I have been having issues with my Droid 2 Global with the touch screen. From time to time it will go crazy and start typing or opening up apps. Sometimes it will open the apps around the lower part of the screen and other times it is an up and down motion that continues untill I lock the screen. Locking the screen will fix it sometimes others I have to pull the battery. I have had this issue with several Roms. I ran 2 different RCs of Venus and now I am running CM9. If anyone else has heard of this or knows something I can try please share the info. Thanks.
Yes, I had a very similar issue. My phone would detect screen presses around the bottom, usually near the unlock slider. It would actually cause my phone to open up my email and delete things on its' own. My only temporary fix was to lock the screen, try to wipe it off, and then unlock it again.
It's a hardware issue with the glass/digitizer, not a software issue. I fixed it by buying a replacement screen on eBay, and haven't had any problems since. If you do replace it yourself, make sure to do it in a clean environment with no dust, and save the tape that covers the speaker, or else dirt and dust will get inside the phone and make the screen look dirty.

Screen and reset help

Trying to get my sons unit to work, first thing was the screen was unresponsive, I read to try a factory reset, seeing as the touch would work, I tried the volume/power button. After many attempts I finally got that to work.
navigated around with the volume button and selected reset. Now I am stick in the select Language which I can do but cannot continue as the next button is unresponsive.
I am think of trying to get a new screen etc .. would it just be the glass or both screen and glass . (if someone could clarify which and what to order)
sorry if I am totally stupid android etc is new... been a windows man for many years
Open it up and see if any cables have come loose, they are renowned for pulling out the display cable if they are dropped, possible it could affect touch too
The display cable is wrapped around the battery, which shifts when dropped, and pulls the cable out
sounds like a good idea, as I got him to own up to having dropped it and the back un snapped. will check that out tomorrow. thanks
I found one flat cable with the lock clip up, tried again got a lot of the touch working, just the bottom 3 back-home etc that will not respond. wonder if I have missed something like another cable or something.
I'd hazard a guess that it would be that one cable, maybe not fully making contact with the port it was pulled out of, I'd try fiddling with it more, see if it changes the places touch isn't working
Also check that the cable isn't damaged, they are pretty thin, possible it has ripped inside the shielding
Sounds like you're on the right track though
Check that it is not just those three navigation buttons not working, such as the whole bottom 1cm of the screen - rotate the screen, see if the touch points are dead in the same places
And I'm not 100% about this, but check if the screen end of that cable is removable too
thanks my friend, yea I rotated the screen several times and those three will not work. I did have a funny effect before I did another reset. I would try and press the reset in settings and the wi-fi settings would open. lolol after playing around I finally got it to work. I will keep fiddling.
2nd eldest daughter handed me her ipod with a lovely pattern of cracked glass.. so ipod added to my list.
Oh the joys of kids and expensive tech!
If the buttons won't work in any orientation, it sounds more like a ROM issue for that problem, if it was touch, the same part of the screen wouldn't work in any orientation, meaning the navigation buttons should work in either portrait or landscape, whichever is the opposite of the non working orientation
Good luck

Black screen except for camera? J7 Crown. no USB debugging. Recovery mode access

Situation: Samsung Galaxy J7 Crown. Never messed with. USB Debugging not enabled No special permissions (no ADB). I am able to access the Android Recovery screen. Obviously wipe cache partition didn't help, nor Lacking storage booting. Other than the Recovery and download screen: I get the Power/Restart icons when booted normally. Reset works, but power doesn't turn the phone off. No phone calls, Yes notifications. Camera from lock screen comes on (triple click on home button) and touch screen works.
I've tried to trace out the lock pattern in the hopes its still working outside this specific situation. No indication that it is.
All i want is a few sentimental pictures. Although after an entire day of frustration, finding out that the only thing that works is the camera is kinda funny and ironic.
Ive looked on XDA forums, but I'm having no luck w/ exact situation, although I'm sure someone has been in the same situation or similar enough.
Spent all day looking at options (Odin?) and nothing looks like it would work out for me.
Knowing the camera works, makes me hopeful that a mirror would work? No reaction to lock screen pattern makes me think not.
Additional (maybe irrelevant) info. Shows up on home WiFi while Find My Mobile said it was offline (makes sense with Notifications/no calls)
Any advice? Just point me in the right direction if there is one.
If not i hope you appreciate the Irony here. Thanks
(I used to be not so bad tech support, but haven't been keeping up as of late, and today was a painful reminder. Take pity on me.)
Black Screen Except Camera - Galaxy J7 Crown
Hey there anick22! I was so glad to see a search result with something referencing the camera working, on an otherwise completely black screen! I was super bummed to see that noone had replied to your plea for help with this insane problem!! I hope you found a solution by now!!
My 2 month old Galaxy J7 Crown suddenly went black on me one day, and it didn't happen as a result of a drop, or spill, or any other damage. I don't recall having put any new or different apps on it, recently, either.
The triple click of the Home button does open the camera, and the screen lights right up, perfectly. It takes it's usual beautiful pics, and I'm able to use all of the camera functions. I'm even able to view any photos I took during that particular session, buy not any prior pics, because I'm unable to unlock the phone.
"Hey Google!!" also reacts, and will display the result of any question that I may ask it, but I'm unable to go into the answers, without the ability to unlock my phone.
I have been able to get the phone into safe mode, while attempting to power it off, by pressing the power button, and then tapping on "power off" (although this hasn't worked every time I've tried). While in safe mode, "safe mode" is displayed in the bottom left hand corner, but nothing else appears on the screen.
Upon powering up the phone, all of the normal things happen. It shows "Samsung" and goes on to the blue screen to show the "Trac Fone" logo, but once the phone is booted up, the screen is black!!
PLEASE tell me that you were able to find a solution to this!!! I went and purchased a new Moto G7, (since I had a Droid Turbo 2 in the past, and it was amazing!!), and I'm beyond ready to get back to my J7 Crown!! PLEASE HELP!!
Thanks so much!!!
By the way, I'm a newbie here, as If you couldn't tell!!

Question how to fix random black screen after opening phone

My z-flip3 5g has a strange problem. If i close it (by folding the screen closed), then after opening (unfolding) the screen and touching the right side button/fingerprint reader to unlock it, i hear the quiet "click" noise that indicates the phone is unlocked, but the screen stays black. i then have to repeatedly push the lock button on the right to lock the phone again and unlock it again. after several attempts the screen finally turns on. sometimes it will go black a few seconds later and the same issue continues. but other times the screen will stay on and work fine.
i have noticed that if i do not close the phone (folding the screen together) then i do NOT encounter this issue. the phone screen turns on when pushing the right side button (or touching the fingerprint sensor) and everything works fine.
this issue started yesterday, a system update installed yesterday as well, could it be related?
i already restarted many times, booted into recovery mode and wiped the cache. nothing has helped. the only way to avoid the problem is by not closing (folding the screen shut) the phone.
One UI v 5.1
Android 13
Security patch level Feb 1, 2023
fully stock/not rooted
I have same behavior. Did you solve this problem?
Unfortunately no. Did a factory reset, hoping that would help, but the issue persists
Mine has recently started doing the same. Last update was right before this started several weeks ago. I don't have mine set to require fingerprint, it should just turn on after opening. If I open it partway, it will turn on, then turn back off when fully opened.
hi,
i have same problem, it's software problem?
Not completely sure about that. They update this thing so often, it could be coincedence that it started shortly after an update. I want to try blowing out the hinges as I've got some dust under there that I hear when opening the phone. Definitely not a phone to put in your pocket after working in the wood shop!

and donĀ“t take it to the beach either!
What is also strange is that when I close the phone and open it a few seconds later, there is no issues whatsoever. However, if I leave it closed a few minutes, then when opening it, the problems with the screen staying off happen.
Yes, definitely don't take it to the beach!
@netridah , mine is doing exactly that. Which makes me wonder is it a wake issue, or a mechanical/sensor issue with the hinge.
one more to the bill
I checked the flexes and I warmed up the logic nothing works
I have the same issue: Flip 3 - 5G with OneUI 5.1 - 1 April Patch level
When I open the phone I eventually see for less than one second the lock screen, the goes black and unresponsive.
Then I have to press the button to turn the screen off (even if it is already) and then re-press the button or use the fingerprint to turn it on and it will work (eventually, sometime I have to do it a couple of times).
I already googled it on many forums but no solutions, I've tried to:
Disable the always-on display - no result, at first looked like it did the trick but the day after was having the same issue.
Check all the updates of the system components like always on-on display (settings --> lock screen --> always on display --> info), no help everything is up to date.
Hi,
I have the exact same problem, only difference is that I'm on the z flip 4.
I get the black screen and sometimes when opening or closing the phone the screen can flash in a bright yellow or green color.
I got a motherboard but the problem continued
Next step changing screen is very expensive at the moment
This is driving me crazy - also started the day I updated to OneUI 5.1.
Hoping for a solution soon!
I am also encountering this problem, I went to samsung repair shop 1 month out of warranty, sales person said it is a screen issue and needs to be replaced for 430$. Mine was before the update, i took mine near the pool, got wet maybe, as the alarm for usb charging mentioned unplug it immediately, day after it began randomly dark when phone is openned fully. Zflip 3
Oh just an update, i did some tinkering today, Good lock all updated, disabled clockface, sprayed some contact cleaner on power button, and hinges, fold close and open for a minute or two, fell asleep for 1 hour, and when I woke up, my screen works back to normal, it wakes up when unfolded, no more waiting or hitting the power button several times. hope this stays like this.

Hi, few days now, I still have occasional blacking out, I've tried putting my phone on safe mode, and this seems to solve the problem. I suspect it may not be hardware fault, but 3rd party software, "good lock" or something else that conflicts wit one ui, that makes the flipping open lag waking up. Contact cleaner used for electrical stuff
Didnt use my z3 for about a week let the battery drain.. then charged it too 100% without turning on the phone.. my phone back to normal now.. hope it works for you guys
Hello,
I am using Z Flip 4 and last night I started having this problem as well. I can confirm 100% that my phone has no hardware nor a history of impact of any sort that's why it's really frustrating having this kind of problem.
Has anyone already found a resolution for this problem?
Z flip 4 here also. Had the same problem with the screen. Took the phone to Samsung and they changed the screen, frame and back panel's for free under warranty.
They said it's a hardware issue.
So better to take the phone to Samsung.
