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?

[Q] Disable Hard Reset

I would like to write simple security app for my phone, that wouldn't allow manipulating with mobile after it is ordered to enter disabled mode. I thought about it, and there are 2 things needed to be done. First I'll have to disable screen - not a hard task, but secondly, I need to ensure anyone won't be able to hard reset phone until mobile have disabled state. Normal reset won't be a problem, I plan to start that security app right after the phone powers up and load windows.
If the phone won't respond to commands and to perform hard reset(which would allow bypassing app by wiping it), phone is useless to anybody.
So if I want that to work, I need to disable hard-reset option by any means, but not disable whole phone.It got to be able to power up so app can again run and undo all changes. Is there any way to do that and don't break anything?
I've seen similiar app to what I want build, but it disabled phone totaly, so even after recovering it, it was unusable. That is where I want to improve, so I'd be glad if someone could help me.

i know nothing about mobile programing, but got some though regard what you want to achieve, you may need a customized password protected bootloader.

hey, this sounds like a cool task. I can help with the SPL modification.
you would also want to protect it from reflashing with another ROM.

I think it might be just enough for now If we could password protect our systems from being wiped/flashed, but as I read, this wasn't possible. I'm not sure if times changed, but with android and win7 becoming popular, I doubt that anyone will take an effort and I don't know enough to make it by myself...

this can be done in several different ways by changing SPL...if you're interested PM me and I can sort something for you.

This will be cool app .
I think what cmonex said may help by securing SPL itself, to start with.
Thanks.

Disable Hard Reset?
I think someone has already done that - and sent it to me in a virus in an MMS. My phone keeps wanting to "Power Off". If I respond "Yes", it immediately restarts. If I respond "No", it wants to "Power Off" again after a couple of minutes. The phone doesn't respond to the power button. I can't perform a hard reset.
I've been trying to find a copy of the shipped ROM to try reflashing it, but none of the links to the Australian Telstra ROM (2.31.841.6) seem to work. Can't seem to find one ANYWHERE?
This is driving me CRAZY.
Is there any OTHER way of doing a hard reset (eg while connected to PC?)
PS Oddly enough, it seems that while the phone is connected to the usb port of the PC, it DOESN'T try to power off! - Whoops, cancel that... "Power Off" dialog just came up!

[Q] Wifi Error - Continuosly switching on/off

Hello guys, it all started with not being able to connect anymore to my wifi and so (among other reasons like clearing the memory, the cache and just startin' over clean) i decided to factory reset it.
Since then if i try to turn on the wifi it just keeps on switching on and off. I can;t really turn it off permanently either cuz it's gonna turn on again but not stay on.
And doing so (turning on wifi) really slows down my phone it's like going in slow motion and the only way to fix it is a factory reset (after which, of course, the Wifi is set to default to Off and stays like that if i don;t try to turn it on again )
If i don't turn it on the phone works perfectly, no bugs no nothing. Actually it does have a 'glitch', it doesn't let me install the Androzip app...for some reason, no idea if that's helpful but that's what it is.
I really hope it's not hardware cuz i don't have warranty, what ever idea or advice u might have will be much appreciated.
Thank you

Common guys, really no idea? If u guys don't have a clue about what could be wrong it says pretty much about my chances of getting it fixed..
I would like to try to flash it with...some software...i don't follow up on the existing mods out there.
I would like to know what is the latest known with no bugs, or at least no bugs with wifi and/or mobile data connectivity cuz that's what i want to test.
And, also, i' d appreciate some pointers on step by step instructions, how to flash it...if i need any drivers installed, what programs to use, how to use. I'm sure there has to be something like this around but i don't know where to look.
Thank you very much...

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.

Start a chat with Samsung. They have always been good to me.

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.

phone turns off by itself

Hi, this happend already to me few times so I decided to put it on here.
Sometimes when I pick up my phone and try to unlock it nothing happens, fingerprint and button all the same it looks like it completely Off. Then i have to press few times a button to actually start it and it's booting. There is huge battery loss after it boot up. See image.
I am in Stock 4.0.2 no root just few standard apps installed. Nothing fancy. This happend already few times to me. I left the phone locked and when I want to unlock its dead. Also it is behaving weirdly, when I turn it off manually I just need to press longer a button and it's turning on, but here I need to press it few times to work.
Does it happen to anyone else?

Honestly, there's not enough information to understand exactly why it's happening. You need to get a logcat in the time before the reboot; unfortunately, logcats get erased during a reboot so it might be a little tricky getting it if the reboot is seemingly random. Someone had posted this as a possible way of getting the log:
"Retrieving the logs is tricky, since the log cache gets erased on reboot. If the phone reboots even while sitting on a charger, try running adb logcat continuously (you will need Android SDK and USB drivers installed and configured on your PC.) When the phone reboots, look at the last several pages in the command prompt window for any errors or abnormalities."

Otherwise, it's hard for anyone to help. I'm not much help in actually figuring out the issue, but I know if you can get the log, someone else probably can help.
For more information on logcats: Logcat Tutorial

Yeah I was trying to connect it to PC but nothing, so it is turned off. I will try next time to run command when turning on, maybe there will be something but I do not see it working before it gets erased. I was hoping that anyone else is having this problem so it might be rom related. It is completely random so you can;t guess when it happens.
I had it only few times so it's not super annoying but still it is not normal behavior. In addition it is weird that battery went from 55% to 33%, just phone reboot will not drain that much... I hope there is nothing wrong with the phone itself.

Check in advanced to see if schedule off is on

Nope it's off

Happened to me to on 4.0.2. Rebooted twice a day.
Solution to me was Qualcomm flash back to stock 3.5.1 and uodate from internal to 3.5.4. OTA 4.0.2.
The theard "how to unbrick".
Not one reboot until now in days.

I think I found a culprit responsible for it. It is Hill Climb 2 game which doesn't close properly sometimes and I think it causes some kind of crash in the system. Is it possible?

It's possible. Not necessarily the reason, but it might be. Either uninstall the app or freeze it using Titanium. Greenify might also work, but that allows the app to start itself up and potentially continue the issue. See if that stops the crashes for a couple of days.

The problem is that it doesn't happen often and only when I quit the game and lock the phone immediately after that. I am not sure if that's a reason though, just guessing because it happens after this last time. I will uninstall this game anyway, it's just time eater
