[Q] Blank Screen but phone is on and can receive calls - Galaxy S 4 Mini Q&A, Help & Troubleshooting

I have a korean version if the s4 mini. My phone has a blank screen. It does get on, all sounds play phone calls come and o swipe to pick it up but the display is jus blank. Tried to go in download mode but same blank display. Any help would be really appreciated. I'm far away and cannot claim warranty.

So after 2 days the phone is back on. Removed the battery and tried everything. It just popped back on itself. No idea what's happening. Any ideas?

My guess is that you have that one in a million defective screen

Tilt 2 freezing when locking phone...

Has anyone else had the problem with the Tilt 2 freezing when locking the phone? It doesn't happen all the time; but every so often, it freezes on me and I have to reset the phone to get it to work again. I haven't come across a solid answer for why it does this, so in the meantime I've reverted the locking mechanism to the Windows classic version, not the Windows default version that comes set on the phone. I do like the idea of the sliding unlocking mechanism, but I don't want to deal with the freezing. Is there a fix for this problem?
You are not the only one. I was wondering if it was S2U2.
I have been leaving my phone unplugged over night the past two nights to get a feel for the battery life. When I go to wake the phone in the morning it was either a blank screen or just the title bar before it froze. I had to reset to get the phone to work again.

I've had bad experiences with S2U2. I had installed S2U2 on my 8525, and I ended up having to do a hard reset. One day, after having to power down and restart the phone, it just wouldn't load. It got stuck in start-up mode. I don't plan to use S2U2 again. I'm not sure if the slide mechanism that comes standard with the Tilt 2 is related to S2U2 or not...
I am wondering if it is a conflict between the NEW WM lock slider and S2U2. I have a corporate exchange, so I have to use the PIN access.
I have the PIN set to appear in one hour if not in use. However, when using the WM slide locker, it ALWAYS reveals the PIN pad. If the PIN access did not appear after every WM slide locker, I would use it.
I changed the settings in for the WM lock to use the classic - thus eliminating the WM slide to unlock.
I will leave it OFF the charger tonight and let you know the results tomorrow.
Switching to WM Classic for the lock screen seems to work.
The screen did not freeze when I went to turn off the alarm this morning.
So the solution to use S2U2 is to change the Lock screen on your device from Default to Classic.

Thanks for the follow-up. Yeah, I've done the same thing: switched from default to classic. Thanks again.
Screen Unlock Freezes on Tilt 2
I too had this problem right out of the box. I switched to the Windows Classic as prescribed. However, this prompted me to get out the hand held drill and put a small hole right in the side of the back cover. I found myself having to battle the back cover every time I needed to soft reset, plus I noted the stylus needed to be removed to properly seat the back cover upon reinstall. Now I simply pull out my stylus and stick it in my hole. STOP IT!

Screen Unlock Freezes on Tilt 2
I just recently purchased the HTC Tilt 2 from AT&T on 02/15/2010 and for a few times I can successfully use the screen lock and unlock feature but then it stops working and I have to go press the soft reset button. This is constantly a problem now. When I try to go and unlock my phone it allows me to move the little lock icon to the left or right but the screen remains locked.
I appreciate the suggestions to dumb down to the Classic mode but this is not acceptable for a brand new device. I hope HTC comes out with a hotfix for this soon! We need to make this issue known to HTC so they can begin debugging immediately. Or do I have a defective phone and I need to return my phone?

I have seen a post similar to this pop up multiple times in the past month. This guy was specifically having problems with his mail client.
http://forum.xda-developers.com/showthread.php?t=634213
Personally I have only experienced this issue when the phone was next to my engine getting 400° temps blasted on it. Its hard to say the actual cause of the problem, but it seems in ideal situations (no 2000 e-mails or excessive heat) my phone is free of any freezing or strange behavior.
*edit*
also at the end of that post another user posted a work around that seems to be helping.

After returning my first HTC Tilt 2 phone and I got a second one, I got the same problem again.
I think I found the screen lock bug for the HTC Tilt 2 that I am able to reproduce. The problem is when I enable the Owner Information [Identification information or Notes] to display when the device is turned on and then try to slide the lock icon it will not unlock the phone.
HTC, please look into fixing this bug. Thanks!
Here are the steps to reproduce the problem:
1. Press the Windows logo start key (the second key on the bottom of your phone).
2. Choose Settings.
3. Choose Personal.
4. Choose Owner Information.
5. I populated everything on the Identification tab as well as a note to contact me on the Notes tab.
6. Choose the Options tab.
7. Check mark either the Identification information box or the Notes box.
8. Click OK
9. Now lock your phone by holding down the end call button.
10. Power off your phone.
11. Power on your phone.
12. Try to unlock your phone right away by sliding the lock all the way left or right.
13. You can slide the lock icon all you want but you will never get to unlock your phone.
14. You now need to soft reset your phone by taking the back cover off and using the stylus to press the side reset button. :-(
I hope this makes it into a downloadable bug fix. In the meantime, I have disabled (unchecked) any Owner Info notifications on device power up. I really miss having this on device power up as my old 7 year old Nokia phone was able to do that without a problem.

[Q] Locked Cracked screen Help!

Hi, I have a very big issue, I dropped my SGH-M919 from a coffee table to a carpet, which seems like an innocent fall/drop, but in this case it wasn't, my digitizer broke inside impeding my ability to see anything, all I have is a blank screen, I can hear notifications as they come in as well as incoming calls, but can't do anything about it, I already have a replacement on the way from tmo, but my main problem is, How do I get my pc to recognize my phone so I can transfer some important data and pictures I have, FYI I have a screen lock 4 digit pin....I'm I really screwed or is there a way for me to recover this data??? Thanks in advance for any help....
P.S. I'm running stock.
Can you get ADB to work with the screen locked? Maybe if ADB work you can ADB pull files. I don't know if it will work just throwing out ideas for you.
If all you have is a blank screen you may be in luck!
1) are there any visible cracks ?
if yes, you may be SOL but doesn't hurt to try step 2.
if not
2) is the blank screen black or white?
If black, try shining a flashlight at an angle. Your LED backlight may have broke or connectors are bad. You might be able to see everything.
If white, google Galaxy S4 disasembly (try ifixit) disassemble your phone and make sure the video flex's and connectors are secure. I drop like that can easily dislodge them.
What data are you trying to pull?
Apps, can always be redownloaded. Purchased apps are attached to your google account as well as contacts and a slew of other things.
Music and Pictures can be pulled just by plugging the phone in and exploring.
SMS and Call Logs, I don't think so unless you get the screen replaced obviously. Replacing the screen does not wipe ur data.
He will not be able to explore phone unless lock screen is disable.

He wasn't very clear about his damaged condition. If you read my possible solutions you would realize screen lock is irrelevant.
If his backlight is out, the flashlight will help him see where to enter screenlock. If his flex is loose disassembly and reinstalling correctly will fix the phone.
Notice how he said "my digitizer broke inside impeding my ability to see anything" implying the fact he doesn't realize the digitizer has nothing to do with his ability to see the screen as that has to do with the LCD. He just says blank screen so hard to tell his problem.
Once you receive your replacement, add the same lock screen and use that as a guide to where to touch.

About screen turn off and on problem

Hi,
I am using Note II, stock ROM and unrooted....Only install a few apps like facebook, line, whatapps, viber, candy crush.....everything works fine....
I found a problem and hope friends here can give me some advices...
My screen turn off during answering call but sometimes the screen won't turn back on automatically when I move the phone away from ear....I have tried the following when the screen remains off:
a) open and close the flip cover
b) move the finger to cover the censor and then move away
c) shake the phone up and down
d) turn the phone back and front
All the above actions failed to turn the screen on..I have to press the home button in order to turn it on..
I already check the censor in #*0*# mode and the censor works well...
I am wondering why sometimes can work, sometimes cannot work..
anybody facing the same problem? is it software bugs or hardware failure?
Thanks for help!!
P/S:
I have done censor test in development mode, factory reset and clear call cache.....
Don't know why sometimes still failed to turn screen on....every time my wife complain the screen won't turn on, i told her to dial again, like to those customer service line which need to key-in menu selection 1-2-3-4-5, the screen turn on well to let her key in number....wired....
maybe like 70% success 30% fails...
i also get this most of the time. i talked to 2 reps at local stores and 1 had just recently heard the same complaint about the same phone. it is likely the proximity sensor.my screen even goes dark before i put it to my face so if i wanted to use speaker and / or input anything, i couldnt even if i wanted to. i have had to wait a whole minute a few times before the screen comes back on or reboot the phone. i talke to samsung tech support to ask if i send it in will the sensor be replaced with a known good part and i kinda got the runaround stock answer . ( theyll test and fix or replace with refurb) which means i am likely to get the same issue.
dunno, otherwise great device.

Notification pulldown don't work

So i just got my phone back from service. I had a white spot on the screen. They fixed it by replacing the motherboard. It'll all fine and dandy right there. But i noticed i could not pull down the notification bar in potrait mode. While switching to landscape it works. This sounds like a hardware issue but im not sure. Is there a way to test the screen?... if a move a widget to the top of the screen from my homescreen. The screen detects it's up there.. so i guess the touch is ok?
The service took about 4 weeks so i hope i don't have to send it in again
I've tried resetting the phone (clean install)
UPDATE: Sent it back for another 4 weeks of service..
Hello
To make a touch screen test follow these steps:
1- open the phone dialer and dial this number *#*#3421#*#*
2- Choose accept, that will take you to a hardware test page
3- Choose touch screen line draw test.
Thank you
i have the same issues its software and gets fixed automatically
but there should be a solution
I just received my brand new HTC 10 today and I have the exact same problem as you.
I am unable to pull the notifications bar after I unlocked the phone in portrait mode. However I can pull the notifications bar while the phone is still locked AND when the phone is unlocked and rotated to landscape mode.
I have tried factory resetting my phone and upgrading to the latest software but the problem still persists.
What should I do?
Anyone solved this problem?

It's a screen issue. Do a line sensor test from the help app
