blue screen flash when unlocking? - Galaxy S III Q&A, Help & Troubleshooting

hi guys so updated to the xxela firmware through kies about a month ago. since then every now and then when i press home or power to wake the phone up before it goes to lockscreen my whole screen flashes blue. literally just for a split second, but should i be worried?
unrooted, untouched, completely stock. uk, 16gb 4.1.2 JZ054K

I haven't seen that myself, try turning off all the lock and security options and see if it does it when waking straight to the launcher screen - it might just be a 'fight' between wallpapers?
When you updated was that the whole ROM or just the bootloader? Did you factory reset afterward? A lot of people updated just the bootloader and mix the two together, there isn't a firmware as such on this phone.
As you are wholly stock and if you updated just the bootloader then it might be the various OTA updates. I'd be tempted to wipe the phone and install a whole fresh ELLA ROM, modem and RIL.

[Q] 4.0.3 no lock screen

I updated via Kies to version 4.0.3 and now I have no lock screen. I've tried using slide, face, pattern and pin but when I wake my phone it goes straight to the home screen. Holding the power button also doesn't bring up the power options .eg. flight mode, power off and silent, it just turns the phones straight off. I asked Samsung about it and they just said sorry try doing a factory reset, I did and it didn't help. I used odin and went back to stock 2.3.4 (the lock screen worked fine on this version) and then updated again but I still have the same problem.
Country - United Kingdom
Phone - Unlocked
Model - GT-I900
Baseband version - I9100XXLPS
Kernel Version - 3.0.15-I9100XWLP7-CL340913
Build number - IML74K.XWLP7
Any help would be much appreciated.
Thank you
do *2767*3855# couple times, if that doesnt fix, use odin to flash. and after flash do the code once more.

Sounds like you are either missing your /efs/imei/keystr file, or it is corrupt, or has the wrong setting in it.
Google this: "site:forum.xda-developers.com i9100 ics no lock screen keystr"
You will need root to apply the fix you find. If you don't want to root, you will have to go back to Gingerbread.

Changing Firmware - small problems

Hi,
Originally my phone was from the UK Carphone Warehouse (CPW)
I have upgraded it from 2.2 to 2.3 etc...
The last time I did a firmware upgrade to ICS was a few months back and I didn't have any problem doing it.
After the upgrade, I had a few bugs. I used this file - GT-I9100_XEO_I9100XXLPW_I9100OXALPW_I9100XXLPW.tar and the main bugs I have are - The screen won't lock and when I press the Power Button, it will turn the screen off but when I hold it for 1 second the phone closes down.
So today I thought, lets see if I can change my firmware to a CPW version, so I downloaded GT-I9100_XEU_I9100XWLP7_I9100XXLPS_I9100XEULP5.tar and installed that. It went through the usual stuff and upon restarting I was getting an "android.core" crash. The screen stops working and after several reboots nothing change. I also booted up and cleared the cache, and this didn't do anything either.
I have just reverted back to the first ICS upgrade but still has not screen lock or when I press the power button for 1 second it closes down.
I wondered if anyone else has had these problems or could recommend to me what may fix it.
I appreciate all help
Thanks

You're in the wrong section, this has nothing to do with development

First of all wrong section mate... By the way u hav written it seems that u hav not wiping the DATA or factory reset after every flash. Try wiping DATA before and after flashing.. Also wipe cache..

[Q] Phone completely freezes after ICS update. HELP!!!

Hi guys,
I have a huge problem. I had a stock GB firmware customized by Optus (carrier in Australia) on my S2 I then decided to change to the new ICS 4.0.4. I downloaded the stock unbranded firmware from SamMobile (Australia 2012 September 4.0.4 I9100XWLPW, I9100XSALP6, XSA) I updated using Odin. Before I did the update I reset the phone, did the update, it all went smoothly. After the update I reset the phone again and then proceeded to reinstall all my apps and restore my contacts, sms, etc.
The phone works and all functions on it work, however now very randomly the phone would totally freeze. The phone would be in standby, the screen would come on and it would be frozen. The screen stay on all the time and it does not respond at all. It will stay frozen until I restart the phone by pressing Home+power buttons to restart it.
After restart it all works fine for a few hours, sometimes a day and would just lock up again. The phone is not rooted and as I said i just changed the firmware from the Optus branded GB 2.3.6 to unbranded stock ICS 4.0.4 by using Odin.
Is there a way to find out what is causing the phone to lock up like that? Any suggestions would be helpful.
and then proceeded to reinstall all my apps and restore my contacts, sms, etc.

I hope you haven't restored any data app?

I made sure that I didn't restore any data apps. The only apps that got restored are the ones that get automatically restored by Play store.
I have disabled the live wallpaper that I had and it seems to have stopped the freezing for the moment. I will report on what I find out.
In the mean time if anyone else has a similar issue or has a definite solution please let me know.
Thanks
i know this is a resurrection, but don't see it has been resolved.
also found same/similar problem on another topic, but no resolution either.
couldn't find any resolution anywhere on the net, but possibly i'm just missing it (searching for wrong parameters?)
anyway, a friend of mine bought second-hand (third or even fourth hand to be precise) i9100 with 2.3.6 (stock KI3) on it. the guy who sold it to him said something like: "it works best on 2.3, on 4.x it's buggy".
it was working fine, but friend wanted newer OS, so we tried update. it didn't work, and i found out CSC was broken/missing. somehow i managed to repair it, and update was finally working, but was unable to find any for our location.
so next step was to find stock rom that would work on the device, and then i tried four different 4.1.2 stock roms from this topic.
after flashing it through odin, every one was acting fine, until couple of minutes after it started freezing or rebooting randomly.
then i tried flashing CWM, and flashing from sd card, but it was all the same.
wiping data, cache and dalvik cache, prior to flashing. wiping data after flashing...
nothing seemed to work.
GB works rock solid, ICS works better than JB, but stills it freezes or restarts randomly.
tried CM10, but all the same, except it works a bit faster then official JB. but who cares about speed if it freezes/restarts constantly?
back to who knows which build... freeze... samsung galaxy s2 - i9100... with yellow triangle... booting stopped.
so i decided to dig deeper, trying to find hungarian stock build (country we were told the phone came from) not being sure that KI3 is what the phone came actually with. i found 4.0.3, put it on SD card, wiped data, cache, flashed CWM, wiped data, cache, dalvik cache, flashed 4.0.3 from sd, wiped data, booted, entered location for updates - hungary. update found, hooray... downloading... installing... rebooting... working?
nope... it's worse than ever. trying to log onto google account. typing in email add.... freeze... switching phone on - freeze... thinking about... freeze.
i couldn't sit still. yellow triangle, all those reboots/freezes... at least i wanted that triangle gone, and without a JIG, there was only solution for me was to try triangle away. it wasn't available for download in my country from play store, so luckily xda was there.
somehow i managed to download it from the device, install it, click remove the triangle... it did it's magic, rebooted... and miracle happened!
no more freezes.
so i started torturing poor phone, benchmarking, playing games, listening to music.... it seemed stable for about an hour.
so i said to myself:
- it's possible that previous owners tried to upgrade it to newer firmware, and somehow screwed up the bootloader, which was fixed by this app? maybe that was all there was from the beginning? why not try putting 4.1.2?
and i did... took 4.1.2 spanish build from already mentioned page above, flashed it... and voila. working JB... torturing the phone... playing with it... hour passes, another hour...
friend wakes up... takes his phone in awe, starts playing with it.. we talk a bit... and then that look it just froze again!
from that moment on, the phone again starts restarting or freezing randomly...
and, yes, i still have no clue what could be the cause. it doesn't matter if wifi is on or off, if you're talking on the phone or not, bluetooth and gps are always off. only thing that he noticed is that it usually happens while he's using the phone (meaning: operating the digitizer or buttons). if he starts music playback and not touching buttons or screen, it will probably play for hours.
one more thing, but i doubt it would be the case. the battery in the phone is not original one that was shipped with it, but a quality replacement.
it doesn't feel as if the phone is overheating... so i don't know what else i could do with it.
for now, it's back to 2.3.6.
we both lost a week, torturing ourselves with this problem.
i don't know is there anything i could add more?
all suggestions are welcome.
cheers
Maybe try kernel cleaning script and try philz or siyah kernels.
You shouldn't have to flash a custom kernel so your phone won't freeze, but yes, you could run a nuke script in order to wipe clean all custom ROM's leftovers.
Try flashin' jb via mobile odin, see if it keeps freezing up on you. If so, nuke it up.
Sent from the little guy
i'll try them out.
probably for the weekend, if not sooner. will report back here with info.
any other suggestions are also welcome.
thanks a lot.
cheers
ok, so here are some updates.
i finally got my hands back on my friends phone, and tried nuking remains of older flashes.
following that, i flashed stock spanish rom from above mentioned page, updated after installation to spanish update... and after a few minutes, sudden reboot...
so, went back to nuking, and flashed stock hungarian 4.0.3 i found elsewhere (mentioned in my earlier post. don't remember origin... if i find the link on another computer where i downloaded it on, i'll post the link). tried updating, says no updates found.
started torturing the device. it seemed solid, but battery reported it level was low, so hooked it up onto charger and all seemed well. but phone seemed a bit too hot.
after few minutes (this was all about half an hour to hour after flashing to 4.0.3), again freeze.
after rebooting the phone, battery was at 9%, as if processes were draining battery faster than charger recharged it.
so, i figured i gotta try original battery. so i switched his battery with genuine from my phone.
phone seems stable and less hot, for now.
still checking if it is going to freeze or reboot again.
it's about one hour since battery change. still on charger and using wifi and playing around with apps.
i'll check in with news later.
cheers
I have the same issue.but my battery is original.
What I noticed that the phone stuck when I receive an update notification.
Can I stop softwsre to ask for updates? ???
Sent from my GT-I9100G using xda app-developers app
^go to settings, about device, software update and detick auto update. that should stop it from trying to self-update.
ok, so here is an update to my friend's phone status.
currently on hungarian 4.0.3. about 3-4 freezes/reboots a day. sporadic connection breakups during calls. also, when we talk i can hear myself back. this brings me to conclusion it has to do with modem firmware. i found this topic, so i'll try putting that and see what will happen.
if that doesn't solve anything, my question is this: is there any way of knowing which firmware/rom was originally put on the device, since i don't know the real background of the device? i.e. some way of entering IMEI and finding out what should be on it?
cheers
EDIT: tried KH3 modem, no changes... i could still hear myself while talking to my friend on that device. also, it froze couple minutes later. going back to 2.3.5-2.3.6 for now.
so after couple of months, i finally got my hands back onto this phone...
gave my friend my phone, so i could play a bit with this faulty one.
i have played with it for a couple of days now, and here are things i've tried.
i received it from a friend with 2.3.5 on it which had triggered custom binary counter. he's been using it for couple months without any problems.
so i rooted it and installed triangle away again... reset counter, cleared and flashed hungarian stock (telenor) 4.1.2... random freezes again.
tried several stock roms, mostly hungarian ones (4.0.3, 4.1.2). even reformatted with .pit file... random freezes.
reformatted again with .pit and put XXLSJ, installed stability test and let it run...
cpu stability test 15.5 hours no problems, no freezes. then i realized it didn't have a sim card, so i rebooted phone and installed sim card. let it test cpu+gpu for 9 hours... no errors, no problems, no freezes.
so i thought, maybe it's all fine? but it wasn't! as soon as i took phone into my hands and started going through menus it froze!
so i tried SGII_repair, rooted and did "repair"... but nothing changed... still random freezes.
if i just let it do the stability test, it'll probably work forever.
things i've noticed:
- serial number is wrong format (14 hex digits instead of 11 alphanumeric)
- during stability test, cpu frequency dropped from 1200 to 800 mhz (maybe because it was getting warmer? 42-43C during cpu only+charging battery, and about 39-40 during cpu+gpu test)
i tried to find out which firmware is latest according to serial number via kies, but it gave me error.
i know it's from hungarian market, but don't know which exact part of it (branded or not).
don't know what previous owners did to it, and don't have backups of original efs or anything original.
i just want to make it work, don't care much about custom firmwares. i'd be happy even with unrooted stock... just for it to work!
i have no ideas what else to do.
anyone?
finally, as i couldn't resolve the problem, i returned phone to 2.3.5 and sold it as is.
thanks to all people who tried to help.
cheers

[Q] 4.3 OTA bug for SCH-I535

After updating to the OTA 4.3 my S3 now has a glitch causing the screen to occasionally black out, mostly during phone calls but also after screen timeouts when i hit the power button to turn the screen back on it'll stay black for awhile, the menu and back buttons light up and the touch sensor still works even when black. it work flawlessly before the update. I tried to root and was successful at it using the saferoot method but because of the know being lock I can not install a custom rom or recovery and the problem was still there because I was still using the 4.3 rom. So I used odin3 vs3.07 and put the stock rom back on and unrooted and the problem is still there. does anyone know how to fix this glitch or does anyone know how i can go back to the 4.2.1 rom or install the 4.4.2 rom because 4.3 has been nothing but a headache for me.

[Q] 10 second lag on lock screen (wake up from sleep)

I hope someone has some experience of this problem, I will do my best to explain in some detail.
It is as out of the box currently running version 4.0.4 firmware.
The history, initially stock firmware version 4.0.3 was running, the USB was a little loose, so I swapped the complete pcb with another S2 I have with a faulty display, to make things a bit more complicated I also put in a 2Gb SD card, when I rebooted the problem appeared, on pressing the power button to wake up, the screen comes on to the lock screen in dimmed mode, and it will stay like it for anything from 5 to 15 seconds, then the screen will go to full brilliance and the screen can be unlocked.
What I have tried, removed and rebooted with sd card removed, swapped back the original USB pcb, and swapped back again as the problem remained, also upgraded to firmware version 4.0.4, that is more or less where I am now, the problem remains.
Have tried researching but unable to find anything relating to this problem, do you have any ideas?
Update:
After further reading, it appears the original firmware may have been customised, because I was not able to get Kies to connect with the device and the CSC was stated as 'unknown', which from what I have read indicates a custom ROM.
Having flashed the stock firmware , on the recovery menu I get still the message #Manual Mode# Appling Multi CSC.... Applied the CSC code: XEU Successfully applied multi CSC, which was also present with original firmware but it never actually applied the code as it stated CSC 'unknown'. but I can now connect with Kies and the CSC code is stated as I9100XEULPA.
Is it normal to get this message at the recovery menu?
Is it a symptom of the same lock screen delay issue?
Solved
I spent 6 weeks trying to fix this, the most aggravating of problems are sometimes very easy to cure when you know the answer!
Disable auto brightness, easy, your long wake up delay has now gone.
Let me know if it helped you.:good:
