screen freezes when i wake my phone

Ever since i manually updated to frf91 sometimes when i try to wake my phone my screen freezes an i can't unlock it also when i try to power my phone back on it will vibrate 7 times an it wont come on. I guts take the battery out an put it back it to get my phone to turn back on. I've never had this problem until i manually updated my phone. I did a factory reset an it helped for a while but the problems come back. Has anyone had this problem an does anyone know how i can fix this? I'd really appreciate any help i can get

Help please

Is the bootloader unlocked?

this seems to be a common issue with FRF91, although most people's phones will unfreeze after a minute or two, does your backlight turn on and off when you press the power button?

whether it unfreezes after a minute or two depends on what it's doing..there have been many times where i have to pull battery...........

ya i have had to as well but most of the time it wakes just fine

No my bootloader is not unlocked an yea the backlight will come on but it won't unlock. Ive never tried waitin a min to see if it fixes itself i just usually pull the battery when it happens an sometimes when i try to turn my phone back on it does the 7 vibrating thing. Like i said before it never happened until frf91

I have an app called AutoKiller installed. It tweaks the Android system's inner memory management routines. it was set to something other than default. I changed it back to default, and haven't had a problem since. if you have this installed, maybe try and switch it to default settings.

Sounds like a data issue. A factory reset only wipes user data, You must wipe in recovery to wipe rom data. Also make sure you have the correct radio for the build especially coming from lower build. If that's the issue flash radio first to support the build. Then flash the rom.

How do u wipe in recovery? Yea im a newb lol

Also if i wipe in recovery will i still be on 2.2 or will i have to update to it again?

Phone keeps shutting down

Today my 4X encountered a strange problem: It shut down itself (I thought the battery was empty and charged it), and after restarting it just shuts down immediately. It shows the lockscreen saying "no SIM" and then shuts down. Anyone know a solution to fix this? I suppose a factory reset might do it, but I don't have a backup now and would like to keep my data.

If it is the SIM then try a different SIM, or put a folded piece of paper between the holder and the SIM - I always do that with phones just to make sure it keeps good contact at all times.
Other than that, no real idea mate - sorry

I think it should also work without a SIM. But as said, it just shows the lockscreen for ~2 seconds and then shuts down. I have tried without a sim, it's the same. I'll try with a different one, but I suppose that won't help much. I think i'll also try a kdz reflash, but i'll have to set up my father's PC to do so. Just thought maybe someone knows a quick solution.

Alright, i've just done a kdz reflash - same situation. Is there a way to adb pull the /data/data from any of the other modes (recovery, Emergency etc.?)

Weird... Reflash use to replace all files and stock settings unless you have some app avoiding them to run... Reflash don't delete installed apps most part of the time. If you have frozen apps they'll remain frozen. Did you factory reset before reflash?

No, as said i wanted to try everything before doing a factory reset (don't have a recent backup because Ubuntu won't recognize the MTP mode properly). I have restarted the phone many times before without that strange behaviour and didn't freeze anything since then. I just can't tell where the problem comes from. BTW, the SIM is recognised now (after the reflash), but still shutting down.

You notice some over heat, you try to use it without SD card, it keeps rebooting when charger is connected?...
Cause appart of hardware malfunction, I can't see any other reason... of course we don't know if the system file is corrupted or not...
If the phone is ON time enough, you can copy the data files/ folders to your SD card, after save them all you can factory reset...
Wait for better help cause I have no idea... sorry

It's not because of heat, the phone is really cool. It just stays on for a second or so, just enough to see the lockscreen or the "Enter PIN" screen and then it shuts down. It's like the battery was empty, but it's charged. It even shows the charged battery symbol. Guess I'll have to do a factory reset and lose my data. As root is gone, I also can't boot to the bootstrap recovery (with this method) to backup there. Should have done that before doing a reflash...

You can try to downgrade before factory reset... some apps won't work but, maybe the phone just don't turn OFF and you'll be able to save your data.

So downgrading didn't work either. I'll use the LG Support Tool to upgrade and factory reset now (with data loss). That should hopefully fix it.

Well, the LG Support tool also didn't fix it. Data is lost now, so I can freely do whatever I want
I've tried to get into the "low-level mode" (http://forum.xda-developers.com/showpost.php?p=35524491&postcount=11), but no success. Can someone point me into the right direction and on how to press those buttons? I've tried several combinations, but they all didn't work out - either the battery symbol appeared or the phone booted to recovery or to the "do not touch cable notice" mode.
As far as I understand I should do the following steps:
1) Remove the battery and USB cable
2) Insert the battery and plug in the cable. The phone vibrates once, then shows the LG logo, then shows a battery symbol and then turns off the screen.
3) Press Vol+ and power and hold it. The battery logo shows again. There is a sound indicating that some device is connected to Windows. The screen turns off and there is a sound indicating that the device is disconnected from Windows. Let go off the buttons.
4) Press the buttons again until there is a sound indicating that a device is connected to Windows. Let go off the buttons. The screen should remain off.
Is this correct? What am I doing wrong? Do I have to wait at some point for some action? As said, all I ever got was the "battery symbol" again (for a few seconds).

Once that data is gone, just reflash the phone.
My advice, like always is, downgrade, factory reset, upgrade , root, factory reset.
hope you don't tell me that you have problems with flash method...

I have tried that. Flashed v10a, wiped data in recovery, upgraded to v10h via LG Support Tool. Still shutting down. I thought the emergency recovery might fix it but I cant get the emergency mode to work. I'll call the LG support tomorrow and hope they'll bring me a new phone.

If when you're flashing, you use "web upgrade" instead of normal upgrade, it will upgrade with LG Tool, official firmware, what it means that is the same than the emergency recovery that you're trying to use.
The difference is that you don't need to use IMEI. The detection is automatic.

Thanks, I thought the Emergency Recovery was still different. So no chance to fix this now. LG's support won't work on Christmas, so three more days stuck with it.

I got the phone back today. Put the battery in, started, and... it shut down. AGAIN. They were supposed to fix that! Anyone near me who has a spare battery for testing? After all that might be faulty.

It goes down when charger is connected?

Yes, it does. And it recognises the battery as full, that's why I don't suppose it's because of that. But one never knows.

mines done it a couple times recently too! just living with it till the update!

Problem solved. A new battery did the trick. But I still don't know why it would shut down with the old one.

Xperia z wifi failing

My wifi stopped working since 2 weeks ago after a abnormal crash. Every time when I try to turn on wifi, it keeps saying turning on, but never did. Which causes the Stamina mode not working anymore.(and I think the phone keeps attempting to turn on wifi also increases battery usage) The Bluetooth also stopped working since then. I did factory reset number of times and Repair with PC companion, still not a chance.
Finally, I found a temp. solution, which I completely drain the battery and charge it from 0% to 100% with phone off. It seems this could reset the wifi problem. But once I connect back to my home wifi, it would cause an abnormal freeze(notification led become RED) and then reboot automatically, and then wifi stop working again. I searched a few posts and some people with xperia S had a similar wifi problem, but no solution.
I got a feeling that something crashes the wifi driver, and this cannot be reset either factory reset or SUS repair. Is there anyone here got a similar problem like me? Or anyone could explain what actually happening to my phone?
Thx

Did you had any luck with your WiFi? I have exactly the same problem,it keeps turning on without able see any network and the battery discharge faster.This happened to me after installing the app of dsploit,Tried to re-install the rom and re-lock the bootloader but still the same.

You better send to service center for repairing than fix it your self,very waste time and your money.if like to fix yourself better go to buy ap set not original.thing wisely,Man!!

Do you know how much money i will pay? because i have unlocked the bootloader and i think it voids the warranty because i did that but i will relock it when i'll give it to the service center.

i had same trouble then, but when i restore my backup its working great again! :laugh:

My Note does not starts, please help.

First I want to apologize if this issue is already treated in the forum, my English is not so good and I don't know how to find it. I will appreciate if someone can help me to fix the problem or to find the right thread.
The phone was working normally, battery was fully charged, then it started to change the bright of the screen and suddenly the battery was low. Some seconds after that the phone turned off and it does not start again. When I try Samsung Galaxy Note logo appears and then it turns off again. If I try recovery mode it doesn't start but I can put it in download mode if the phone is charging. (If not, a no battery message appears). Anyway, I cannot backup and I cannot use the phone. Android version was up to date and the phone was rooted. I would like to backup it if possible but if not I would like to tray a hard reset, but I cannot do this without recovery mode...
Thanks

You could start with trying a different battery.

I will try this, I get the battery in 2-3 days. If not I will tell in order to try other solutions. Thanks

I think the problem is the battery, too.

It was the battery, with a new one works fine.

S4A Occasionally Won't Wake from Sleep

I can't figure out what's causing it. I don't have very many apps installed that didn't come with the phone, and any I did install were from the Play Store. I haven't done any modifications such as root to the device.
In order to bring it back to life, I have to either hold the power button down for 30 seconds to shut it down (or take out the battery) and power it back on.
Interestingly, if I have notifications waiting and the LED is flashing, that continues to flash even if the phone won't wake up.
I did 'disable' several of the bloatware apps in the app management area in Settings. I'm starting to think that must be what's causing it. Is there a particular bloatware app that should never be disabled? One that would cause this issue?
Other apps I've installed are things like Netflix, eBay, the app for my bank, and a TV-listings app. Pretty basic stuff. I don't think any of those would be the problem, would they?
Remaining battery doesn't appear to have an effect. It's happened with full battery and somewhat low battery.
'Services' that I use are Exchange push email and Gmail. I also have it Bluetooth synched to my car's hands-free thing.
Any help would be appreciated. Taking my phone out of my pocket to use it just to find that it's not responsive is very troublesome.
Thanks.
EDIT: For clarification, this is an AT&T version of the S4A.

maybe u can enable back all the apps that u have disabled and see if it happens anymore.
u mentioned "the phone won't wake up" and "not responsive". do u mean that the screen stayed off and u are unable to get the screen to be on?

That's right. None of the buttons wake the phone up or turn on the screen. I can tell the phone is still 'on' though. It's not like it got powered off in my pocket.

The advice you've got is sound - if you think it might be because of disabled apps, re-enable them all and see if it keeps happening. If it doesn't... well then you disable them one at a time until it starts happening again.
Then you come back to the forum again and let everyone know which app never to disable.
If it doesn't stop happening after re-enabling all the apps... well then my guess would be a faulty device. Can't think of any other logical reason for it to behave like that. So try the apps first, if that doesn't help, "return to sender".

if enabling back all system apps do not resolve the problem, try disabling all user apps to test. one of your downloaded app may be the cause.

Alright, over the past month I've done a bunch of testing. Here are my results.
1. Re-enabling all the system apps didn't help.
2. I uninstalled all my user apps. Didn't help.
3. I completely reset the phone to stock settings and formatted all storage. That didn't help.
4. I figured maybe it was something with bluetooth since it seemed to happen after I used bluetooth devices. I disabled bluetooth completely. It didn't help.
I'm out of ideas for the moment. Could the phone just be bad? I would wonder why the issue only happens occasionally.
Thanks.

Solved, rom change and ready, do not turn off more

I have the same problem in i9500. I now live in China and have purchased an s2, s3 and now the s4 from China Unicom. I have successfully rooted and flashed new ROMS (latest HK stock firmware) on the S2 and S3. When I bought the s4, it worked fine. I immediately flashed the latest stock HK ROM using Odin 3.07, After flashing, the phone is unresponsive after going into deep sleep meaning that nothing happens when I press the power button. After a long press of the power button, the phone will re-boot. Sometimes I have to pull the battery. Again, this phone is totally stock. I haven't added any applications. I re-flashed the stock China Unicom formware and I took the phone to the Samsung Service facility and they did a new flash. Phone worked great. I take it home, flash the HK ROM with Odin...same results; phone is unresponsive after going into deep sleep. I return to the Samsung service store and they again flash the phone. Phone works fine. What are they doing that I'm not doing? Could the partition table get corrupted during my flash processes. Should I try another version of Odin? Should I try a PIT file and try that? I'm downloading the ROM's from SamMobile. Thanks in advance for any suggestions.
Edit: I fixed this problem by upgrading to 4.3 which brought it's own set of problems.
