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
Every time I turn wi-fi on, it simply says "Unable to scan for networks". Does anyone know how to fix this. I hard reset and that didnt help.
Try a full power outage. Pull the battery. Sometimes you need to clear voltage from hardware (especially radios) in order to clear the glitch.
If you find it necessary to do this a lot, there is a deeper problem.
If this fails, take it into the store.
I took it to the store and they said its a known bug.
They said they are fixing it in an update soon.
I don't know if its true...

I had the same problem, it started when my phone dropped below the threshold for the power saving mode, I believe I went into those settings and disabled some things and got it working after a reboot (turn fast boot off)

I'm just going to wait until the bootloader is unlocked and then flash Cyanogen mod 7 when he makes it for the Evo 3D
I'm having a similar issue, my wifi goes into sleep mode and says "unable to connect to wi-fi" when i wake the phone up, but then immediately connects back to wifi. I tried changing the wi-fi sleep setting in spare parts, but nothing fixed it.

Do you have wifi set to "never sleep" in wifi settings??? Also if your running spare parts+ it also has an option to set wifi to never sleep. Also are you running any apps that puts the phone to sleep??? Also in display settings try changing your screen off time to 10 min.
Locked & Loaded
I tried the "never sleep" setting in spare parts, but the setting doesn't hold when I exit the program and open it again, it goes back to "android default". I don't see anywhere in the phone wi-fi settings to change the sleep options.
I'm unaware of any apps I'm running that put the phone to sleep, and I'm not sure what the display settings accomplish but I can try it.
None of this happened before, only thing that really has changed for me is that I got the iGrip car dock and the phone has seen dock mode a little bit. That and I went to a house with spotty wi-fi and my phone would connect and disconnect at the range of the router. I've had other issues with app/camera freezing, I'm hoping it's sd card related or perhaps due to ota's not taking correctly. I'm gonna try a sd card format/phone data reset to see if that remedies all the issues, otherwise I might go in for an exchange.

BS. You shouldn't have to wait for a custom rom for your phone to be running normal. Take that **** back again.

This happens to me. I have noticed it only happens if I have had my phone get below 30% battery at some point and the power save mode kicks in. For some reason it is not switching it back once power save mode is disabled.
Sent from my iPhone with the bigger GeeBees.
The setting isn't located under Wi-fi, look under Power, you should see the options in there. Turn power saver off, or adjust it's settings, and see if that helps, I wouldn't use spare parts
I did a full phone/sd card reset, and the problem STILL exists for me. Spare parts did restore itself as one of the applications that got restored, I uninstalled it without running it though. My phone settings seem to have gotten reset as well. I don't get it, my phone was fine even with spare parts installed before.
I might try another reset and see if spare parts still restores itself.

I got my original TB on release day and everything has worked fine with BT pairing and connecting to my 2007 Audi A3. My phone then ran down the stairs without me and used insurance to get a new phone from Asurion. Everything seems to be the same on this phone, but BT will not connect to my car. I have tried everything from changing my syncs, deleting FB, un-pairing and then re-pairing and everything else I could find doing searches on here and google. Has something in the hardware changed in the more recent phones? I am beyond frustrated!
When I try to go to settings on the TB, I can get to the options page and the "phone" option is checked but the "connect" option is unchecked. If I try to check the "connect" option, it tries to connect and then is dropped again. I can also uncheck the "phone" option, but clicking on the "connect" option checks both boxes, tries to connect again, and then BT is dropped once again. Any ideas???
Hi,
This morning I randomly decided to update my firmware (as per Sony's incessant reminders). I updated to 17.1.1.A.0.402, as it was what Sony's updating app was telling me the latest firmware was. I updated as instructed on my tablet, wirelessly. The update was successful and totally uneventful -- no incidents whatsoever.
However, immediately after my update, my wifi dropped, and after that, I couldn't reconnect to *any* wifi network whatsoever. I toggled on/off, and the wifi would reconnect for a matter of seconds, maximum 2-3 minutes before dropping and never reconnecting again. To reconnect to wifi, I'd have to toggle off/on again and then would have seconds to try and load a page (but would never succeed)
So, I updated the firmware again, this time using the update application for the Mac since my tablet could no longer connect to wifi.
I successfully updated to 17.1.2.A.0.314.
Still the same wifi dropping and not coming back issues.
Then I tried "repairing" my software from the Mac, which I'm lead to believe erases everything and flashes with the most recent firmware.
Still had the same wifi issues.
Then I tried an erase/factory reset directly from the tablet.
I still have the same wifi issues, but they don't kick in within seconds anymore. Now after several minutes, the wifi will drop and not come back.
Any suggestions for a fix? I'm as of yet unrooted, and would like to remain that way if possible...
Thanks!
I would suggest a factory reset after flashing the update. Might solve your problem.
Before that you could try to delete your Wi-Fi and set it up again...

Thanks for your help
"Repairing" from this Mac app is flashing the update, correct? It erased and then flashed anyway. Had to set up the tablet like it was new. Is that not a factory reset?
In any case, I did a factory reset immediately afterwards, from the settings screen of the tablet, as mentioned above.
By "delete your wifi" do you mean "forget" the networks I'm trying to connect to? If so, I've done that many times, and have had to re set up my wifi networks anyway upon each factory reset/flash/erase.
So I think I tried what you suggested, and no dice, unless I've misunderstood?
Perhaps worth noting: I'm using the accompanying Sony Bluetooth keyboard.
Wifi seems to stick around a bit longer when Bluetooth is toggled off (no keyboard), though I could use the Sony keyboard before the update, no problem at all.
Yes that was what I ment.
Sorry it didn't help solving your problem.
Seems like you should call Sony.
It's the Bluetooth. Wifi and Bluetooth are on the same chip and won't work at the same time. It's a hardware fault with pretty much every Android system I've used. Turn off the Bluetooth and your wifi will be fine.
Thanks for your reply – though it was possible to use the bluetooth keyboard at the same time as wifi before the update.
Bluetooth keyboards would be pretty pointless if you couldn't use wifi at the same time as you use the keyboard, wouldn't they?
Between the Sony Xperia Z2 tablet, a Samsung Galaxy Tab S, and an iPad, I've used all with bluetooth keyboards + wifi without issues (until this firmware update on the Z2).
Use 5GHz Wifi, then the problem will be solved.
Sounds like you have been lucky so far and due to the small amount of data a bluetooth keyboard transmits. Bluetooth headphones are always transmitting as is wifi when watching hd youtube videos. They will always interfere with each other, but only every minute or so. Google the problem and you'll see its pretty universal.

Hi, here's my experience with my Z2 tablet, unrooted. I too have had wifi problems: after using the tablet fine for a while, with a strong signal, the tablet drops out, then wifi access stalls whilst "Obtaining IP address". I sometimes use a Bluetooth Microsoft keyboard, but have had the wifi drop out when I have Bluetooth off.
The only reliable (so far) solution I have found is to move to a static IP address. Not ideal, and perhaps not much help when travelling, but an OK workaround for a home or other wifi network where you have admin access to the router.
Hope that helps. Apologies if my newbie post is naive.
So I know this topic has a few posts many a year or so old but I'm looking for a possible work around for this issue. Here's a background of what happened:
I have a rooted note 4 originally running cm12, I wanted to return to a stock build and when I did something happened (can't remember what) and my wifi stopped working it would click on them immediately off my first thought was kernel so I flashed a new one but didn't help I tried a different stock build 5.0.1 instead of 5.1.1 but still same issue. I went back to the cm12 and that seemed to work fine still, I looked for another stock build because I'm stubborn and flashed a different kernel than the previous ones I've tried. This seemed to fix my wifi issue at least for a day then back to the same issues. Anyway here's what I've been messing with to try and figure this out.
I'm focused around the file wpa_supplicant.conf as I've tried restarts and all that but that won't do anything. What I have noticed recently is when I don't have any networks saved in that file I can toggle airplane mode and try toggling wifi, after a few sometimes dozen attempts it comes on and works fine so long as it stays on. If I turn it off I have to restart my process of going into wpa_supplicant.conf>deleting my saved network>toggling airplane>then spamming wifi. As I'm able to repeat this it leads me to believe it's not hardware related, slim chance on loose cable, But if there's a way to prevent the system from auto saving a password that might help with a workaround. I've tried changing that files permissions as well as the ones in the system>etc>wifi folder but they get changed back
Anyway I'm still working on finding the root cause but will update if I find anything also tried deleting the wpa file and that works to after a restart but issue comes back and so does file which doesn't seem to me that its a corruption issue
Update:
So I somehow crashed my Samsung messenger app switch to hangouts and then back so decided to wipe my phone and refresh the OS. I factory reset then advanced wiped cache, dalvik, system and data. When it rebooted I tested the WiFi in the system setup and it worked fine I could turn it on and then off normally so I decided to continue setup once fully setup and no other apps installed I retested the WiFi. It worked fine I connected to an access point and it stayed connected I then forgot the network cycled wifi and tried again and again still worked so I let it sit and would test it throughout the day. About an hour or so later the problem reappeared which was odd. I did my old workaround deleting wpa_supplicant.conf and toggling wifi until it turns on. I got it to turn on and connect to my home WiFi and left it, so far I've kept my wifi on and it's stayed active for 24hours now and reconnects fine to my home router when I'm in range and back to lte when I'm away so right now it seems I can have wifi if I don't toggle it off. Still not sure what's causing this issue as since I'm currently using wifi to write this I don't see it as a hardware issue. After trying multiple kernels I don't see that as the cause either, although possible. Will keep messing around and update if I find anything further
Update 2: so far I've been able to keep my wifi working great as long as I keep it on and don't toggle it off. Doing this has kept it active and auto connecting to my home wifi for a week straight. I make sure to keep wifi I during sleep so it won't disconnect but it also seems to stay active through restarts which is great. This still leads me to believe it's software related and not hardware but not sure where the issue is.
Update 3:
So far I've just kept my wifi on while trying to find the issue. The only other issue I've come across was since my wifi is on 24/7 and auto connects if I want to use my lte instead i have to either turn off wifi or forget my home network which neither is an option. But I have found a solution:
I was able to add a shortcut to my home screen that actually disables the current wifi connection without disabling wifi and forgetting the password. To do this you must have Tasker just create a new task in second tab, I named mine disconnect wifi, click the plus sign and select "net", next select "wifi net" there is an option that says disconnect. Have that selected then go back and thats it,add in icon on bottom right to use as a shortcut. I've tested this and it works great one tap and it disconnects the wifi but keeps wifi turned on and if I want to re connect just go into WiFi settings and choose the one to connect to
