Hi guys. I'm totally new to the android/smart phone world btw. Anyways, I recently got my Samsung Galaxy S2... first thing I noticed, my touch screen wasn't working. I popped the battery in and out and then it started working as it should.
My phone was working fine this morning, then all of a sudden out of no where, the touch screen stopped working again. I've tried turning on/off the phone multiple times. I've taken out the battery and even my SIM card nothing... i'm worried.
Has this happened to anyone else? Is there a fix? Do i have to go through Samsung? I hope not. Incase anyone asks, I did not root my phone.
Any help/feedback would be appreciated.
When the touchscreen stops working... were you charging the phone at that time?
The first time i turned on my phone, was actually by accident and it was charging.
However, just earlier now, it was not. it was just sitting on my computer desk. The home button, lock button and touch capacitive buttons work.... but i can't get past the lock screen
you could try a factory reset to see if its software related, but it sounds like hardware. I would definitely Return the phone .
I guess I can't do a factory reset, since I can't get into any of the menus... man this sucks. I spent $900 *gulp*
To do a factory reset,
1. Turn the POWER OFF, pull the battery out and put it back again.
2. Simultaneously press and hold the Volume Up, Home and Power button
3. If the Samsung Symbol appears, release the Power button
4. A Boot Menu will then show, Use the volume up/down to choose wipe data/factory reset.
touch screen not needed this way.
oo that's interesting... I tried it. and it didn't get to a boot menu. maybe I was doing it wrong. I tried a few different ways, but no success. It turns out I have warranty with the store. They're going to replace it for me Thanks for the feedback guys. Awesome forums.
Something similar happened to me yesterday. When I had the in-box USB cable attached to a BoxWave VersaCharger (combined AC/DC charger), and the VersaCharger was plugged into 120V AC, the touchscreen would stop working. As soon as I unplugged the USB cable from the SGS2, or plugged the VersaCharger into a 12V DC lighter socket, the touchscreen would work fine.
I've got the same problem as the OP... I had my phone charging overnight and this morning when I first went to use the phone I could not unlock the screen. I could wake the screen via the home button, and see I had a missed call etc but it just wasn't responding to touch. BTW I can't remember if when I first tried to unlock the phone if it was charging or not but really this shouldn't matter.... oh and btw, I'm not rooted or anything either! Naturally I rebooted the phone but still the same problem....so I tried a battery pull and still the same problem. Just now I did a factory reset but the touch screen still isn't working! I guess this is a hardware problem so I'm going to get it fixed under warranty by Samsung! Gutted that I will likely be without my phone for a week or 2!
EDIT, UPDATE...
Well, I was just on my way to the repair shop Samsung warranty had told me to take it too, and I took my sim card out to put in my old Hero (the only thing I hadn't tried!) and I couldn't believe it but the touch screen started working fine again! Weird, but that is now my advice if anyone else has a problem with their touch screen not working - oh and I took the sim out whilst the phone was still turned on. Crisis averted!
UPDATE 2
Sadly this has happened about 4 times to me now and I'm just waiting for the inevitable next time. Each time doing a factory reset then taking the sim card out seems to bring the screen back to life (though last time not immediately) but I shouldn't have to put up with this. Problem is, I don't want to send off a seemingly perfectly working phone to get repaired as I fear they will struggle to notice the problem, never mind fix it! I'm hoping a new firmware comes out soon, in the hope that it may resolve my issues...
Me as well ...
I have had this happen to me twice now (Touchscreen not responding).
The first time I had just installed a game and thought it must have been related to that. Pulled the battery and no joy, left it for a while and it came back to life...
Second time I was surfing the web and it stopped responding, pulled the battery and left it for maybe a minute but no joy .... pulled the battery again and left it for probably 20min and it came back to life. When it came back up I noticed the livewallpaper had been turned off and my widgets were gone from the homescreen.
What I did notice when it wasn't working was it had "safe mode" displayed at the bottom left of the screen
Have the Same Problem
Have the same problem i Mine and was super exicedat first it worked fine and after charging the touchscreen stopped working i pulled the battery out and put it back in but no luckso im gonna return mine to the shop hope they replace it
Moral:AT FIRST SUPER EXICTED BUT NOW SUPER ANGRY
Same issue - Is there ANY way to save my data before I send it in for repair/replace?
Hi all,
As of this morning, I have exactly the same issue as the OP. Screen doesn't react to touch, with the exception of the capacitive buttons. I found a dude on YouTube that had the same issue: youtu.be/0oIdllWiV4I
The last thing I did with the phone before it started misbehaving was to answer a call. The phone was on the charger when the call came in - I can't recall whether I unplugged it before answering, or after, or at all during the call. Not sure it has any relevance anyway, only mention it because I've seen reports of people's screens no longer reacting to touch when the phone is plugged in to a charger (apparently it even states in the manual that this may happen).
Anyway, whilst all my contacts, SMS, photos etc are backed up to the cloud, the same can't be said for my app data. Before I lose hours and hours of progress in various games, or all my settings in numerous other apps, etc, can anyone think of any way to get access to the memory of the phone, bearing in mind the following:
I can't connect to Kies to pull a back-up because bluetooth is currently enabled on the phone and when one connects the USB cable, it says "Activating USB mode will deactivate Bluetooth. Continue?" but I can't click the Yes button
I can't connect in USB mass storage mode because I can't navigate to the settings menu entry to enable it
I can't turn Bluetooth off in order to get Kies working, becuase I can't get to the settings menu or pull down the notification bar to reach the power control.
I can't use Voice input to control the device (on the off chance there was a "bluetooth off" voice command) because (presumably with the most recent firmware I flashed via Kies a few weeks back) for some reason Vlingo is no longer the app on the double-home button action. Instead it calls Samsung Voice and wants to walk me through a first use tutorial, but I can't click the next/skip buttons
I installed via Android Market push the app belonging to www_remoteaccessphone_com as it promises to be able to remotely switch bluetooth off, but the website says I haven't installed the app yet, presumably because alrhough I was able to install it without touching the phone, it probably needs to be run at least once to set it up, and I obviously can't do that
I can't start Kies Air to try and get my data that way (starting it would require using the touch screen)
Kies via bluetooth isn't supported on Android
Needless to say, the data I'm trying to retrieve is on the internal memory, not the SD card. As you can see I've been trying all sorts of creative things, but I'm fairly sure I'm screwed. Any bright ideas I haven't thought of?

flash it with CF-root, boot into CWM recovery, do a nandroid backup after that, use CWM recovery again to mount USB storage, connect to your PC and pull everything off.

Thanks for the quick advice. I guess I'll need to use my girlfriend's phone to download CF-root and then transfer the SD card to my device. Quick question before I proceed though - is it possible to remove all traces of such tampering, since I've already made out with Samsung that I'm sending it in for repair, and I'm not sure they will honour the warranty if they see it has been rooted etc.

get a USB jig off ebay or amazon to reset the flash counter. should not cost more than 5 or 6 euros, shipped.
anyways you need to flash CF-root through ODIN if you are coming from stock. instructions are all in chainfire's cf-root thread.
Nandroid Restore
So I successfully rooted, used CWM to do a Nandroid backup, mounted the sd_card and saved the contents (including the nandroid backup) to my PC, reflashed the stock rom & kernel, usb-jigged it to get the counter back to zero/original and sent the phone in for repair. My efforts paid off as they repaired it without question under warranty. I just received the phone back and today set about restoring my backup:
Copied the sd_card contents I'd saved to my HDD back onto the phone
Re-roooted it with Cf-mod.
Used CWM to restore the backup I took before sending it in
It restored boot/system/data/cache successfully
selected reboot now in CWM
The result is that it is still missing all my apps. It only seems to have the "data" like my camera shots and SMS messages, system settings like whether bluetooth is on or off, the volume level, Wifi networks etc. So something was restored. But there is no Google Account configured, the lock screen picture is the default not the one I had beforehand, and as I said, all the apps - the main reason I did this whole thing as my personal data is all backed up to the cloud on a regular basis anyway - have not been restored. Am I confused? I thought a nandroid backup took a complete snapshot of everything, apps included.
Finding out the list of Apps I had in order to reinstall them is not an issue - I have a list of everything I had installed saved on AppBrain. But if I reinstall the apps, all the settings (or progress in the games) within those freshly installed apps will be back to square one, not where I left them, right? Or should I reinstall the apps and then restore the data partition over the top again?
Are you guys using any type of screen protectors, cause if you are, that may be the issue s their have been reports that the screen becomes unresponsive with certain screen protectors when connected to a charger.
However, if you are not using a screen protector, then I would suggest getting the unit replaced as you should not have to do anything, root or otherwise, to get the touchscreen working on a touchscreen phone

Nope, no screen protector or any kind of case for that matter. Anyway, that isn't my issue anymore. The touch-sensitive unit was defective, the phone was repaired under warranty. My issue now is getting my apps & settings back. I have meanwhile read elsewhere that Nandroid doesn't back up the apps - pretty deceptive "backs up everything!" "it is like time travel" etc comments around here then.
Anyway, I reinstalled all the apps I had previously, and thought by reapplying the data partition from the nandroid backup it might then bring back the settings for the reinstalled apps. Instead all it did was remove all those apps again - now I am really confused. How come the restore DOESN'T bring back the apps I used to have, but DOES remove the ones I subsequently install. Does Nandroid touch the apps or doesn't it?
Touch screen not working
So i am having a very peculiar problem related to the GT-I9100 Touch Screen.
I bought the phone from Saudi Arabia and I live in Bangladesh at the moment. So for now I don't have warranty.
I bought it on 4th of this month. It had 2.3.3. So I updated it to 2.3.5. I did not use the phone much before that so I don't know if this problem was there before.
So here is the problem.
First time I noticed it when i pulled the phone from my pocket and could not unlock the pattern. First I thought I forgot the pattern. After sometime I noticed that i could not touch the buttons. I was dragging my finger over the points but there was no connecting line. I restarted the set. But it still did not work. After sometime I took the battery out. And after that it started normally and unlocked. And the touchscreen is totally fine.
I tested it using *#0*#. And every single point in the screen registers touch.
After that this happened couple of times. First couple of days I thought it was a pattern unlock problem. But i tried PIN and Password even using no unlock. It happened in every case.
So after couple of days it totally stopped happening.
But from yesterday it is happening again. And today it happened 3 times.
So today as I had no unlock protocol i tried tapping Home twice. As this brings on the voice command menu. And for the first time i was in the phone without touching the screen.And first i noticed the Menu and Back Soft keys works.And the touchscreen still does not work. And i noticed some thing weird. Always some thing in the screen is Selected. In Menu the + Icon is selected. In first screen the Map icon is selected. Also in Recent Apps the first App is selected. So after a lot of reboots it is back to normal again. Now i see something interesting. In the Battery Usage Graph i can see some really sharp drops. 3 times. Looks like when this happens phones charge takes a nose dive.
So here is the Gist.
Info related the Problem:
1. Usually happens when the phone is my pant pocket for sometime. It does not happen if it is sitting on the table.
2. Touchscreen gets totally disabled.
3. I have no idea why this happens.The exact reason behind it.
4. Battery Charge takes a nose dive when this happens. See the attached images.
5. I still don't know how to bring it back. Sometimes a simple reboot works. Sometimes I have to pull the battery. And sometimes it works on its own.
6. Every other function of the phone works. Like music playback using my UE 200vi music keys using PowerAMP, Siri(Android version), Call can be received using headset.
Battery nose Dive:

dl.dropbox.com/u/30943431/SC20111116-202913.png
Also the selection
dl.dropbox.com/u/30943431/SC20111116-202146.png
So this is the thing. My biggest problem right now is, I don't know why it happens and I don't know how to bring it back from this situation. If I knew I could make sure I don't get it again or I would just fix it every-time. As when this happens I cant make calls or anything which requires the touchscreen.
So guys help me if you can by giving ideas. As i will not go back to KSA in 6 months. So buying a $550 phone unlocked was a total waste. As i cant use it here.
Thanks a million in advance.

Hi,
I have problem with fingerprint reader on my elephone p9000. I am using latest softer version and i have this problem from the begining.
So when i try to add new fingerprint it recognize my finger every fifth time, and after i set my fingerprint and lock phone it recognize and unlock phone first few time, and after that i seems like he forget fingerprint and i cannot use it.
Is this system or hardware problem?
After update i factory reset my phone but this does not help.
I find youtube video with the same problem
If you have any sugestion please.
I have the same problem too. I think you need to press the finger well for getting a good result.
I hope that this problem have a solution.

I had loads of problems with the fingerprint sensor.. I was scanning itself (no finger on the sensor, vibrates and returns "too many attempts), working only when the screen is on, not working at all, working 1/10 times I tried, etc...
My problems were all software related (some were registering technique related). It's really not possible that two phones that you have ordered had the same problem.
I have managed to fix mine by combining Resurrection Remix and DarkSense Kernel 1.2.0, now it works 100% of the time. (1.1.0 rendered the fingerprint sensor useless). XPosed and ROM Toolbox seemed to break the fingerprint sensor as well.
I know it might sound silly, but try a different fingerprint registering technique. What I do is I lightly touch the sensor with the centre of my fingertip for the first time, lift the finger up, rotate it by ~5 degrees and lightly touch it again. Do that until most of the finger tip is registered. I'm only saying this because I've seen people touching and "smearing" the fingerprint sensor, expecting it to work. Imagine it's a camera, give it pictures of your fingerprint.
I don't know if this is useful, but after a few months of trial-and-error I've managed to find what was wrong with mine.
I just installed the AEROM V5 and now it works about 90% of the time, which is more than my Nexus 5X did.
I bought an S9+ on launch day long story short it lasted 2 weeks before it would just shut down itself anytime you put it to sleep (screen off). I figured out after doing some tests and research that it would only do it when the fingerprint scanner was turned on. I sent it to Samsung which if anyone has had the pleasure of dealing with their customer service knows it's a nightmare to say the least. At least 2 week turnaround time but in the end they did come through and send me a brand new in box s9+.
Fast forward about a month later the new one is doing the EXACT same thing. If I turn the fingerprint scanner off and just use facial unlock it works fine. I really don't want to go through their customer service again and be without a phone for 2 weeks. I think this very well could be a software issue though factory reset does not solve the issue neither does erasing fingerprint and re entering them.
Has anyone else experienced this? I saw searching google that it is actually an issue others have had and like me, their replacements have all done the same thing. I am yet to find a thread with a solution though. What do you guys think? I'm actually wondering if perhaps rooting it and putting a custom rom on it would help.
Honestly, I have not heard of this before. After you try with fingerprint can you turn the device on at all?
Do you have any apps that may in the background that captures button inputs or fingerprint apps that capture slide movements or anything?

Nope it seems to go off within seconds with the fingerprint scanner enabled. Even if I try to wake it up with the power button it seems to be dead. I've had the phone for about a month now and haven't recently added any new apps. I don't believe I have any apps that would be capturing anything. Is there any app I could use to check and see if perhaps I have something app related thats causing this?
I do believe it's gotta be software related.
You can type *#0*# in the dialer, then go to sensor and scroll down to find fingerprint test
Hi,
I've read this thread and disabled battery optimisation for "com.samsung.android.biometrics.app.setting"* on my Note 10+ and Tab S6 (Wifi).
On both devices the fingerprint scanner is faster :good:
... and it seems to fix recurrent unlock problems with my Tab S6 too
* on some devices it's named "com.samsung.android.biometric"
Important:
it's not known yet if this might have any negative side effects (as battery drain or burning out the fingerprint sensor).
I also did it. But it doesn't make the fingerprint scanner faultless...
Hi, am I the only one having a problem with the fingerprint reader after upgrading to Android 10? ?
I have probably tried everything. Factory reset and clear cache partiotion do not help. The problem returns randomly. The reader stops working, and when I try to get to the settings I have the message: "Finger print sensor calibration needed " or "finger print sensor doesn't respond, try to reboot your device . If the problem persists, contact support "
I checked everywhere and there is no such thing as calibrating the fingerprint reader. Technical support also couldn't help me with the problem, they only recommended to send the tablet for service. ?
The problem has never appeared before the update so I bet that the problem is new software.
Any advice what else I could try?
The reader, when it starts to work, works much better than before the update, unfortunately more and more often it does not work at all.
The strangest thing is that sometimes it starts working after a regular restart. I have no idea what to think about it.
Something similar... It sometimes works like a charm. It sometimes stops working, but no message and no way to use it in order to activate the tab. In that case I have to use an alternative method to. I suppose a fix could be released after this update to Android 10...
solved
Hi there,
I've solved this issue. I have tab s6 4-5 month and I couldn't even register the fingerprint. today I tried again and I found out that you have to touch the scanner very gently, do not press firmly. so I could register 3 fingerprints and it is working. even with unlocking if you press harder it won't work you have to touch slightly and it is working. still it is not reliable as other scanners but it works. i'm providing the video, you can see when I touch gently it is working, but If I press harder it won't register.
