Home buttons, Search button Etc.. Doesn't work! :(

I've tried many solutions, I completely wiped and reflashed different roms. I've also repartitioned my SD (doubt that would do much) .
and still my button's wont work.
Has there been reports of physically damaged bottom buttons? I see no damage whatsoever also lights up perfectly.
Just an idea!
Please help me, its the only phone I currently have in my apartment. Any help or suggestions would be amazing thank you !

Only thing I can think of if there is no damage to the digitizer part would be damage to the ribbon cable that connects the digitizer to the rest of the phone.

That's what I was thinking... is it difficult to open the phone up ? or is very sophisticated with the amount of screws?

Dude I had/have the same issue. I opened up my phone and put it back together. It started working better now. But whenever it stops working momentarily I just lock and unlock the screen.

there is a seperate flex cable for the buttons, it could be this or it could be the digitizer, either way relativley cheap and easy to replace. you can't always see the problem so just opening it up and looking may not tell you the problem.
but like strawmetal said, if there is some corrision on the contact points or some other intermediate problem, just opening the phone, disconecting it, cleaning things up, and putting it back together may fix your issues

Came down to once yesterday. Earlier I even had a thin horizontal strip on the screen where touch wouldn't work. I had a tough time accepting/canceling dialog boxes. This is no longer an issue. Hope the bottom capacitatives don't show any more problems today. Then I'll be back onto the rooted side of android.

EDIT: I got a lot of ghost activity on myscreen today. Fixed by lock and unlock but goes back to ghosting in a minute.

Today I didn't have any issues, phone was working normally, no unresponsive screen at all, capacitive buttons also worked well. It is puzzling...

What do you mean by ghost activity?

Ghost activity = screen being pressed without any interaction.

New and interesting problems

So, I got an Xperia Play a few months ago on eBay, and everything was fine with it. But last month, my front camera started acting funny. It started showing the image in neon green, and then later stopped working in general. It would say "Couldn't access camera" or something like that. Then, a little later, my earpiece stopped working in calls. I would have to switch to speakerphone or plug in headphones to be able to hear anybody. Then, a little later, my backlight started acting funny. It would turn off sometimes, so I could see what was on screen, but not be able to interact with it. Putting it into sleep mode and back out would fix it. But soon, I had trouble pulling it out of sleep mode. I'd have to press the button like 50 times (not an exaggeration, toward the end) Then a little later, I had trouble turning the phone on at all. It would turn on, go the Sony Ericsson screen, sit for about 5 seconds, then the backlight would shut off, and it would stop doing anything. Now, 99 times out of a hundred, the phone won't boot, and if it does, I can't let it go to sleep, or I can't pull it out of sleep.
I couldn't think of any problem that could cause all of these problems. I tried reflashing the firmware, but that didn't fix the problem. Does anybody have any idea? Any help would be greatly appreciated...

When you get it to turn on use flashtool and flash a stock ftf file

I did flash stock firmware. It's still not working... I have a bad feeling it's a hardware problem.

Those same things were happening to my old xperia play which i dropped in water...

Hm... Well, I dunno, if anybody has any other ideas, please let me know. I don't think I ever had a situation where I could have exposed the phone to water

Green tint on the camera means hardware problem. Had those problems with the old K810 Cybershot phones.

Well, anyone know specifically what KIND of hardware problem it would be? I might try to fix the phone if it's not too expensive.

I will probably send it to repair servoce of Sony, my phone is still in warranty (relock bloader )..

Hm... Well, I'm too poor to send the phone to Sony. I could probably buy a replacement part and do it myself, but that's only if I know what part I need. If not, I may just have to put this on the back burner for a while.

Did you unlock your phone by official method
Sent from my MT11i using xda app-developers app

The green tint on the FF cam for me usually gets fixed by a wiping the cam. >.<

I did not unlock my phone. I wanted to, but I wasn't able to

the front cam failure and failure of the earpiece were 2 of the faults that I had as a result of a defective flex cable which was repaired by vodafone under warranty. as it happens, the flex cable on my phone has failed again and has again been sent away for another flex cable replacement
hope this helps

galaxy note 2 completely dead

Hi I have a note 2 and replaced the screen completely before that the phone was working perfectly. I assembled everything back checked that everything was connected putted the battery tried to turned on and nothing. I also connected to the charger and still nothing no charging doesn't boot up. What could be happening here I double checked everything and nothing is missing if anyone could help me I'll appreciate it

Random guess, but like a computer you could have had static electricity and not grounded prior to working and fried your motherboard
Sent from my SGH-T889 using xda app-developers app

man this is scary as I broke my screen on july 4th and is waiting for my replacement screen to arrive. I'm going to try to replace the screen myself. Maybe you broke a wire or something while you were detaching the screen from the digitizer.
Now i'm nervous about doing the screen replacement myself...oh wells, gotta save some money...lol

I think I know why it doesn't work is because I'm trying to use the n7100 screen on my sgh-t889 this version of t-mobile uses the n7105 screen and I bought the wrong one. That's why it won't work

Well, I hate to point out the obvious, but apparently that is not the case.
Did you wear some type of non-conductive gloves when you were doing this? handling circuitry with bare hands is a big no no. It is very possible that you ruined the device simply by touching it.
Here is what I would do (not anything but troubleshooting to pin point a possible problem really):
Warranty the thing.
Good luck.

maybe a defective part..
How do you know the replacement screen is not bad itself..
have you tried connecting it to the computer and getting into download mode or seeing if the phone is ACTUALLY Working..Also a bad or cheap lcd could have shorted something out if you are sure you did not do so replacing it..
Sorry for your luck but it sounds like you need another note 2 phone for some testing. or RMA THE LCD and try another .
Good LUCK

[Solved] Screen comes on but does not respond to any touch

I'll start by saying I don't have a whole lot of specifics on the issue as this isn't currently my phone. I'm looking to buy one and the seller said that one morning the phone would sporadically not respond to touch and by the end of the day wouldn't respond at all. She said that sometimes if she repeatedly locks and unlocks the phone it will work for a short time before becoming unresponsive again. She says there has been no water damage and she hasn't done any sort of software updates recently. She did say that a couple weeks before the issue started that it fell off her night stand but didn't seem to effect it at the time.
My question is has anyone run into this issue before? If so is it a software issue that could be remedied by doing a full wipe back to stock software? Or is it a hardware issue such as a bad digitizer or maybe something as simple as the digitizer cable coming loose?
I did some googling and the only thing I found about this issue was a result of flashing the wrong ROM to the s3. Any help would be appreciated.

This happened to me once. I fixed it by factory resetting and reflash the ROM.

Looks like it'll be an easy fix(fingers crossed). I'll update after I purchase.

Well it appears to be hardware... I tried doing a wipe/reset in recovery and after that didn't help I flashed back to stock using odin. Still nothing so it looks like I'll be replacing the screen.

I was going to say it sounds like the digitizer controller died/was bricked by a wrong rom.

Try seeing if the ribbon cable is loose? Very possible, and would save you quite a bit of money , also, nice to see you on the S3 forums :highfive:!

Forgot to mention it but I pulled the back off and checked the ribbon cable. Removed and reseated it as well as made sure it wasn't corroded. Still a no go but on the bright side I found a nicely priced "blemished" screen on eBay so in a couple weeks I should be rocking the s3! And I'm glad to be in these forums. Looks like I'm going to have more options than I can handle.

If blemished means lightly scuffed just use some glass cleaner on it in a small coat, buddy of mine did that with his iPhone looked brand new.
& yep lol, soo many choices for ROMs and kernels for this phone, gotta love it :good:

So I got bored and disassembled and cleaned the connections on the board as well as the connections on the back of the screen. After reassembling it I get response from the touch screen again although its as though there's a phantom finger making random movements on the screen.

Looks like you've got ghosts
Making the iPhone jealous one user at a time.

So I guess it was just a bad digitizer. Just got my new one and got it swapped out and I'm good as new! Though if anyone else is looking to replace a screen and aren't too brave when it comes to taking a phone apart I would suggest getting a screen that has the frame already attached to it. Removing the screen from the frame and reattaching is a bit tricky.

[Q] no backlight

Hello!!
Well suddenly there was no backlight so i guessed it was the LCD.. changed the LCD but nothing..

Does anybody know what I maybe did wrong?? Did i maybe injure the ribbon cable when i tried to squeeze it through the panel?!?! this phone has really cost me a lot of nerves... please help!!!

hi.
just wanted to chck with you again.. I got a weird problem again.
My phones back camera was not working. giving errors. my friend had a Xperia Play for parts.
I removed that Camera Module and replaced with mine. It started working fine. Cool. I Tried to switch on the Phone while holding the Battery by hand against the Board so I don't close the phone and then see what happened (Worked or not) but it was working so I though success.
I closed the housing of the phone !! Damn phone starts but Black Screen !! Vibrates but black screen !
I kept fiddling and though the flex had gone but no.
I re opened the phones removed the Camera Module.. and Their it starts working again!! I close the phone so I can use it without camera and Boom .. it doesn't work again .. RED Led Blinking !! Phone not recognized by Windows !!
where did I go wrong
PS I had replaced the Flex Cable a few months back and My Phone WAS PERFECTLY working until I opened to Replace The Camera Module !!

Hmmm. i would guess flex cable again, but red blinking could also mean problem with battery (or maybe even flex is even short-curcuit it somewhere)
Do you have some old broken flex that you know that it have working screen? And try with/without camera module
Or try with assembled (closed) part where is screen but keep motherboard part unclosed and try to power up
Just a tip: If you have black screen (and it vibrates ones when powering up) try again to power up but in fastbott or flash mode. If it enter in fastboot mode, but still it give you black screen, then it means that motherboard is working but does not have connections to display
Try to check battery voltage somehow. It must have above 3.2V to be able to charge it.

I thought to update you on this.
my friend had a spare xperia play so I thought to make use of it but its flex cable had problem and screen was Fuzzy and Snowy when switched on.
I believe my flex cable doesn't have problem ,, its the Connector where the Flex cable connects to the Motherboard. I am using my own mobiles "LCD and Digiter portion and his Mobiles motherboard portion" and everything works fine.
but when I connect my mobile to his Flex cable and motherboard portion it doesn't work at all.. same Purple Light when the Kernel boots but nothing on the screen. any suggestions how to fix the motherboard connector or maybe a hardbrick !
