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.

Having the same problem while charging touch screen doesn't work
Stock charger and usb cable
i was on CM7 but that happend so i flashed stock but no luck
I will write more observations
I installed the NFC Ring Unlock application from McLear on the EZ2 tablet, which seemed to function well with my NFC ring.
I did one thing differently, because I don't like to give my Google master password to a 3-party app , I used an app password specifically for the NFC ring, which I considered to be one-time and didn't write it down
Then I had to fly and put the device in flight mode and powered it off some time later.
Now I get the NFC Ring Unlock screen in flight mode when I power up the device, but I can't get the unlock screen to work (NFC is also switched off in flight mode, didn't realise that and the Google authentication is also not working) and I can't get out of flight mode!
What I tried already:
Resetting the device by voulume-up/power, red button in SD-card and PC-companion connection.
Trying to hit the "normal" unlock screen which appears for a sub-second period.
Contact McLear, but they are flooded at the moment, because of the roll-out of their new products.
But neither of this works because they all depend on unlocking the device first.
Any advice?
If your device is unlocked and you have USB debugging enabled, you should be able to deinstall the App with ADB (Adcvanced Debug Bridge).
I guess that with the locked original Sony Bootloader, this doesn't work, though.
You could do a remote wipe with play device management:
https://www.google.com/android/devicemanager?hl=da&u=0
If Sony's software detect it when you connect it to computer, you might also have some options there. I am using Mac and only see repair device ,under the Xperia menu, as a potential solution.
Hey Svan, damn it sucks you are getting stuck by this! Sorry!
1. Did you try posting on the NFC Ring forum?
RE "3-party app" our app never stores your details, we use the Google provided Google Auth libraries to handle the authentication process. I can personally guarantee and promise at no point do we store or use your username/pass, we just get a success/failure callback from them and act accordingly.
2. Is it possible you can use your Google Auth or is your work-around preventing you from doing this?
We're actually just beta testing an updated version of the app that forces users to enter a pin code to handle circumstances such as this. Flight mode and two-form factor auth have been an issue for us so we're taking pro-active steps to address it ASAP This doesn't help you though ;(
3. As BabelHuber asked, do you have debug mode available? If so a simple adb uninstall of the app will get you moving again.
Sorry about the delay through support, I just took another team member on today to help with the backlog, he starts tomorrow so hopefully things will move faster!

Found a solution
I had a the exact same problem, and luckily I found a solution just in the moment I had already decided to factory reset.
I have the stock rom/bootloader/etc installed, no root.
Well anyway, factory resetting the phone is not an easy task either, so this is what I did to get to the factory reset option in the boot loader:
I pressed power for a loooong time, then the phone shutdown, I pressed power and vol-down for a looong time.
Some kind of boot menu appeared, I chose recovery.
At first I was stuck with a red triangle with an "!" over a lieing android. I found that pressing and holding power for 1 second then, while still pressing power, pressing "vol up" for 1 second and releasing both at once, presented me a special menu, wich contains the factory reset and option ... and also a mysterious "wipe cache" option, which sparked an idea of how I might circumvent the factory reset...
I remebered, that after the last OTA update the phone was so busy after reboot, that the NFC Unlock app was loaded after a long delay, while I was already able to interact with the phone.
So I though what the heck, before factory resetting the device I might as will try wiping that damn cache and see wether that caused the delay.
After wiping the cache, I booted and Android went through all those apps, and then showed the launcher/home screen without the widgets loaded etc, for just long enough to switch off the airplane mode, before the unlock app was loaded and immediately locked the screen again.
It might have helped that I disabled the SIM Card PIN check, i don't know.
Only this time I could unlock it normally :silly:
I hope this helps
I purchased a note 4 as a fun project, it has a cracked top glass only around the upper camera, I figured once I reset it, was going to proceed with glass replacement.
I put it aside, now its been a few weeks, so I hope I get the this in order of events.
While I am not expert, I am not a newberry either, but have exhausted my knowledge and searched this forum over, but maybe not using the correct search keyword.
I believe it is complete stock, but has a passcode and/or finger print lockout, so unsure. Still has all the previous user's settings & files.
It boots fine to lock screen. I can navigate to make an emergency call, all screen, volume buttons work, etc.
I simply want to wipe it through the normal stock recovery, but the normal key power+up+home combo is not working, the phone simply boots straight to lock screen every time.
Download mode is also not accessible either. power+down+home, same thing - boots and straight to lock screen.
Every combo of pressing power, volume or home get me to the same spot. Its as though the buttons do not work until it is booted up to lock screen.
I figured I would craft up a 300K usb jig to force download- still no go, same issue - boots straight to lock screen. Even tried variable resistor values, still no go.
I finally was able to get to download mode using Samsung 300K tool program - but even then, the phone will only initiate download mode if I click "connect" at just the right time during bootup.
So I downloaded the appropriate 6.0 android from SamMobile, loaded it via Odin successfully, the download finished, phone rebooted, and continued with android setup ( the screen where android initializes apps i.e 1/3xx, 2/3xx, etc and runs through 200, 300 or how many apps are installed, it takes awhile), so I walked away to let it finish.
I come back - its on the same dang lock screen.
Now I have read that one workaround is to pull the battery after some point to stop the phone from booting, then enter recovery and clear cache/ dalvik.
So I tried that, Odin, download, once phone reboots and vibrates, pull battery - but as stated, still not able to enter recovery.
USB debugging does not appear to be enabled, so unable to try that route either.
At a dead end. Anybody have a suggestion to get this device reset to factory.
I will even take a verbal beating :laugh:
Would love to even get TWRP, but thats a pipe dream at this point.
jammer
I bought a used Zenwatch 2 and after a week it stopped working. When I turn it on it sticks on the Asus splash screen. After talking to customer support and looking online it appears that the "firmware has been corrupted.
I made the mistake of not turning on ADB Debugging while it worked, and unfortunately the screen appears to be unresponsive so I can't even put it into Fastboot mode to turn ADB Debugging on. Of course to make it even better the watch is not recognized when I plug it in because it doesn't appear to boot enough. Since I can't get into anything it makes it impossible to reinstall the firmware.
You all are my last hope, does anyone have any insights into a way to get the phone recognized, or anything that may help? Please help me keep this from becoming a fancy bracelet.
When you first turn it on, swipe diagonally down from either direction to get into recovery or fastboot. I know you said the screen is unresponsive, but if you haven't done it before it can be tricky. Even on a perfectly working watch, I still have trouble getting it to work. Try continuously swiping as you hold the power button, even before the splash screen shows up. If you can get it into fastboot, unlock the bootloader and try flashing my ROM.

That seems to be what I am reading, but so far I have had no luck getting it to trigger into fastboot mode. I will keep trying.
