touchscreen sgs 2 problem - Galaxy S II Q&A, Help & Troubleshooting

Hey, I just bought a samsung i9100 from a network company(orange) with the ics 4.0.4 version on it. Sometimes my screen doesn't work, i mean i'm typing and it doesn't respons but after i turn the phone in lock screen (1 time on power button) it works again. Oh, also it move by itself and if i type on contacts for exaple it execute my command and do one extra touch on some porson from my contacts. I'm convinced that it's a software problem but may i'm thinking wrong?

Must be the touch driver crashing....
*clean your screen, fluids tend to crash touch driver and like you mentioned locking, wiping the screen and unlocking will get it working.
If that doesn't work
*maybe it's because of some app you use crashing/colliding check and see you may might have to try un installing the apps which you installed or updated when the problem started to occur.
*if above two failed try performing a factory reset might help .
*finally flashing a new stock firmware will correct the problem if all above methods failed.

Well.....I think you have just found the answer to your question
Remove it and see if it's all good. If not, returning time it is, don't even bother go flashing firmwares. It's a brand new phone.

Good morning. Guys i was thinking that my screen protection isn't a problem because if i lock the screen and i open it again all works. And sometimes when i'm typeing a text message or i'm on browser it seems to type by itself and i'm looking scared .
p.s : i flashed a new stock rom(4.0.3) , i wiped it and i did all i could. the problem is still there.

Then we might be talking hardware (faulty screen).

Have you tried to clear the data from the camera app?
Go to Settings> Applications> Manage Applications> All> Camera and clear the app data and see if that helps.

Do you have CWM? If yes, then go to recovery mode, wipe cache. Then go to Advanced, wipe Dalvik Cache, ans then Fix Permissions.

Hi, If you did A clean install wich means U did all the wipe of every thing from CWM, and as you said you even installed stock rom, then always facing problem.
I'm afraid your have a hardware failure my freind. somebody must have fallen it down by accident. Unless you bought it like that.
Here's one other thing to do :
Serach for a freind who has the same phone well worked, do a backup from recovery CWM, copy the backup file frome his phone to yours, then do a restore from cwm recovery mode. If it works, then it's Ok, if not, It might be a hardware failure.
I really hope your phone is fine
Good luck.

just download the original apk and install i had the same problem
By chance are you using Siyah kernel 3.1rc6 That kernel has a problem that causes the camera to fail if you are do nothing except upgrade the kernel under no circumstances wipe ANY data since if you are on that kernel you can destroy the internal memory with a wipe that can't be fixed and needs a motherboard replacement.
If when you open the camera a popup says that the camera has failed I would check immediatly if you are on said kernel.
Edit: sorry I didn't notice someone bumped such a old post that couldn't have this problem since it is before its time.
i'm having this same issue. i found that it must be a bad flex cable or connector inside the phone. if i tap hard right under the camera i can get it to fail or not fail without resetting anything in the camera app. thought it was software at first too.
have not opened the phone yet but i figure its either cold solders on the connector or loose connecotor or both. if you throw a piece of tape there inside the phone to press on it then it should fix it.

Slow operation, keyboard and battery issue

Hi,
I have 3 issues. Hope somebody can help:
1: Phone operates too slow. For example when I go to menu, app icons take around 5 seconds to appear. Similarly when I go to home screen it takes the same lag. So much delay that I could capture the screen short. You can see that weather clock and alarm widgets didn't appear. I cleared cache several times n restarts but it works fine for few mins n then again becomes laggy.
2: Keyboard disappears after typing few letters and sometimes it takes several secs to get it back. Reappearing delay is may be related to the above problem of slow response but why it disappears in first place.
3: Battery doesn't charge despite the whole night charging. Its happens not do often but really bugging me. I noticed that whenever I get missed notifications like calls or msgs it stops charging. Not sure why it's happening.
Looking forward to some help from experts. Please note that I feel these problems are occurring more after recent update. I'm using stock Rom of intl s3 version.
Thanks

How to factory reset

Thanks.I have the latest stock firmware already. Do you think stock Rom is faulty? And I should root it and lose warranty. I can do that but is it the only solution?

Ok read It agaIn. Thanks. If thats the only solution, will wait for jellybean update that's just around the corner. I wondered if anything related to hardware or phone settings was to be blamed. But anyhow, thanks.
Sent from my GT-I9300 using xda app-developers app
I am also on XXBLFB and facing no such issues. You should check if some app is not eating a lot of RAM.
Jelly Bean won't be available for this region anytime soon keeping in view the time it took S2 to receive ICS update here.
I suspect the same. my RAM doesn't go below 600mb even if I close all apps and clear ram from task manager. After restart, phone behaves well for an hour but then again becomes laggy. My S2 is much faster than this with lot more apps. This S3 is really disappointing me.

Try to find the culprit app. I have 100+ apps and set is still very very smooth.

That's the status when I just cleared cache.
Sent from my GT-I9300 using xda app-developers app
my suggestion is to do a factory reset (after backing up your contacts, messages, notes etc). then download your apps again and note the behavior of phone after each app. You might find the culprit then. It doesn't seem like an issue with the update since I also updated mine. Also very less likely its gonna be hardware issue.
Sent from my GT-I9300 using xda app-developers app
Maybe the CPU is not working at its entire power. If the factory reset is not working, maybe you should go and replace the device, before it's too late. When you bought it ? If the phone have less than 30 days you should get an instant replace. Not sure that JB will help you, as the installation isn't like a "full format" of your phone
Hard reset: *2767*3855# (no warning message before formating, so type it when you're ready, also remove the sdcard if you don't want wiped too.)
Or *#*#7780#*#* - Factory data reset - Clears Google-account data, system and program settings and installed programs. system will not be deleted, and OEM programs, as well as My Documents (pictures, music, videos)
Thanks. Will get in touch with the vendor for replacement (though I'm sure he will not agree that easily) or else will do a complete reset. I'm really pissed off for spending this much for getting this device. Samsung is very serious in pushing their loyalists away!

Sometimes, there can be some errors. You know, nobody's perfect and we are all humans. After one week after I bought my phone, I found that it have sort of scratch on the screen, but looked like inside of it. It could be seen only in high light. The vendor replaced it instantly. This one is perfect. Love it and is extremely fast and I have many apps on it. Good luck!

Check in task manager, you should have an idea about how is going bad. Also change the antivirus for Avast. Avast is much better. However I recommend without antivirus. I just scan sometimes my phone with it or lookout but never leave the antivirus installed. Is just a waste of RAM memory.
If nothing works do a full backup with Kies and do the complete factory reset.
Most of the apps will be automatically reinstalled when you add back your Google account, but you need the backup for settings and saves.

Uninstalled several apps. Removed widgets from desktops. But still same issue. One thing I'm not able to figure out is why my RAM doesn't go below ~600mb despite killing every task n cleaning cache. I guest a factory reset and ROM installation is the only way out. Thanks guys for all the tips.

Even with all the apps I have on my phone the RAM usage is around 580-640 (stupid SwiftKey using 45 mb most of time) and when I kill the apps I have 430 mb, slowly increasing til 530. Try reset, you have nothing to lose.

Simple, but outraging problem with Touchwiz !!

Hello all Galaxy S3 owners !
I am totally desperate about my phone. IN fact im almost crying.
My problem is simple, trivial, stupid. Yet its totally affecting my work with phone.
I can´t delete home screens in Touchwiz.
Yes thats right, when i zoom out to manage home screens, and i tap and hold to move the homescreen to the delete bar- it just freezes at the first touch with the bar and bam. Touchwiz has stopped, it will restart, and that homescreen is still there.
Pretty simple, huh? Yeah, but well the point is, i have done around 4 factory resets and that problem is still there. When im done setting up the phone, its working good. But the first time i will restart it, i cant delete any home screen again.
Please for the love of god, help me.
What firmware .What phone missing information .

You need to make sure that transition scale is not off in developer options.

God how i hate them, that phone aint that fast now.. Well at least i know whats the cause of it

It's been a while since I fixed mobiles but it sounds like a hardware issue. (I have heard this can be the LCD but it sounds more like the motherboard.)
Have you updated the phone recently or put on new apps?
Before trying to fix it - try uninstalling any new apps, a factory reset or if you recently updated the phone, try downgrading it.
Hope this helps until someone gives you a definite answer.

looks like your cpu got busy that moment. Just do the hardway with unplug the battery.
Unless it happened many times, you'd better do like what jordan0001's suggest, factory reset or upgrade or downgrade

Download a flashlight app (for example, torch, flashlight, etc.) If it does not work, your camera has an issue and needs replaced. If thats the case, buy a new atrix, the flex cable that the camera is on is hard to find.
