phone freezes at lock screen, - Galaxy S 4 Q&A, Help & Troubleshooting

hi guys i have an issue with my device (i9500) since i had a bad efs partition which i successfully restored from a backup.
The device works perfectly, but as soon as you lock it, and wait a few seconds, you can't unlock it anymore. Screen stays black, and the only way to get it started again is by removing the battery. Then it keeps on working perfectly, apps, games, everything is fine, as long as you don't lock it (by pressing powerbutton or auto lock)
Either then it crashes or restarts.
Things i've done already:
- Soft reset
- Hard reset + cache wiped
- tried many different roms
- fresh stock rom installed with Odin.
Problem still persists.

Disable lockscreen till you find another solution.

Windows BOOT SCREEN freeze - Solution found!!!

hello ,
this is for everyone who is currently facing an issue with the phone freezing in WINDOWS SCREEN forever whenever the prophet is SOFT RESET.
After going through the forum & deleting & reinstalling a dozen programmes as instructed the problem persisted.
But here is the real simple solution
Click START ==> SETTINGS ===> SYSTEM (TAB Below) ====> POWER
====> ADVANCED (TAB Below) === > UNTICK both the power off options===> soft reset =====> VOILA !! ====> Your PROPHET WILL NEVER EVER FREEZE ON SOFT RESET .
GOOD LUCK!!
Soft reseted atleast a dozen times & everytime its smooth boot.
FEEDBACK PLEASE ! HAHAHAH!!!
don't think it's such easy but still give it a try
disappoint soon after, my prophet is still freeze and take VERY long time to boot up
boots up fine now
did you "UN" tick the options ??
The prophet has never freezed since I followed the method . It boots up fine everytime.
Yes of course. I think it freezed because of the HTC Home plugin. But it is not freeze forever like you, it just took very long time to bootup.
I do a hard reset to bring back factory setting and it boot fine, install some apps and HTC Home plugin for wm05, it took more than 2 minutes to bootup.
But forget about it, I've just up my prophet to wm06 rom (pdaviet shadow touch edition) and it takes only 30 seconds to boot, sometime it still freeze on boot sceen after I changed something on the setting, which requires restart, or custumize the home plugin. Just soft reset again and it came back to normal
Startup freezes
Hi nannlp
Nice solution.
My Prophet freezes always when starting up. The only way to avoid it was pressing keys continuously.
It works for me.
Thank you very much!!!!!
Boot Screen Freeze on SPL.
I have similar problem the boot screen takes about 10 minuts load in normal startup and if i do something this Bluetooth or WIFI it takes about 6 hours to boot. Tried the given solution did not work for me. I think this is something to do with the overclocking, I was doing overclocking for some time and the freezing issue happened after that. I have IMATE JAMin G4. Otherwise to this issue I love my phone. I would love to get rid of this problem, please help.

[Q] S4 freezes all the time.

I haveS4 (i9505) that had the rom foxhound 2.0 on it.
I later decided to install the Google Edition (http://forum.xda-developers.com/showthread.php?t=2348272) on it.
When installing it I should have wiped data and cache but I accidentally used TWRP's "Format Data" function which deleted everything.
I had to use Odin to put back the original samsung software.
After this I installed the Google Edition the correct way.
When it booted up it said: "encryption unsuccessful" with a button "factory reset" which I pressed.
This took me to the recovery mode which also gave me an error (don't remember what it said).
So i used Odin yet again to put TWRP on it so I could factory reset the phone.
I used the phone for like 1 day but then strange things started to happen.
The phone just froze. Not like a normal freeze where everything stops, but where loading-animations still works and everything else stops working.
So I restarted the phone and it happened again and again and again. From like a few seconds to a few minutes the phone froze or rebooted.
The strange thing is that the same thing happens in recovery (TWRP), the same kind of freeze as described above.
And sometimes the phone refuses to turn on at all. Doesn't help to press all buttons, even holing the powerbutton for 1 minute doesn't help.
I have found out that when this happens I can disconnect the battery and reconnect it after some time to get it to start up again for a short time.
I've tried three different versions of TWRP, and also the original samsung firmware with the same result using Odin.
During all this I also had some problem with my SD-card. Files on it got corrupted and sometimes when i copied files over to it i didn't allow it to happen.
Anyone got any tips on what is going on/what i should do?

[Q] Black edition wont stop restarting after update

Hello XDA,
Today I updated my sisters phone, and everything went well until it came to the lock screen, and then after that, it is only possible to unlock and then it reboots. Even if I dont open the phone, it still reboots.
I've tried:
Clearing cache partition Taking the battery out
but nothing worked..

Not able to start from factory reset again, get's stuck or reboots constantly

hi...
I'm really desperate, my phone is suddenly dying and I have no idea why, I'll tell you from yesterday what has happened:
- I'm playing a stupid game and suddenly the screen goes black. No led, phone doesn't answer any button, nothing. I hold power button, nothing. Remove battery and put again, nothing. After some attempts phone turns on, but just after starting it reboots or stays frozen.
- I decide to change the rom (I had simpl rom), so I do a full wipe and put CM 12. It seems it works, but when I'm in the settings, at the beggining, I don't even have time to put the wifi, it starts rebooting again and/or not responding.
- Desperated, I install via odin the stock firmware from Sam Mobile. It seems it's gonna work, but when the dialog of "Android is upgrading -- Optimazitating app x of XX" it always gets stucked in a number, randomly. I never get to the 230 apps.
- As a last chance, I try Kies to install factory firmware. The same as before happens, but now it's only 17 the number of apps it tries to optimize.
These last 2 times, of course, I enter recovery from time to time (now the default one) and wipe cache partition.
My phone is agonizing, what the f is happening? Does anybody know what could happen?
Please help...

S4 Phone freezes/lags when unlocking

Hello,
I noticed within the last month that my S4 seems to lag when I go to unlock the phone.
I hit the power/home button and the screen doesn't turn on. If flashes on 10 seconds later then goes black again.
After a minute, the phone finally releases itself and then I can use it again, before...
It freezes when texting, instagraming, etc...
I have:
-Taken out the SD card
-Wiped Cache Partition
-Factory reset
The only time it doesn't freeze up is when it's in safe mode.
So I have 2 possible answers: Corrupted system file or corrupted app.
Anyone know how to go about isolating the problem? Or solutions similar to this in the past?
I would completely wipe the phone and reflash the software.
