[Q] Hardware or software problem? - HTC Sensation XL

Lately, my phone has been unable to wake its display from sleep. just the display. but if i proceed to swipe my screen to unlock and press the capacitive buttons, there will be a response (vibrations). This indicates that only the display is not on. If i get lucky, i will get the display back on, however, this is rare. Sometimes, I perform a battery pull and boot my phone, and after i turned it on, the display is not on as well. I was convinced at first that it was a problem with the ROM, but as i changed roms, i fail to see any relation with the roms and my phone as the problem persists. sometimes, if i leave the display on and let it charge(phone set to stay awake when charging), the display will freeze(occasionally), and if i lock and unlock my phone, the display will not be on.
i would like to know whether this is a hardware or software problem

If you have warranty go send it

[Q] [Help] Touchscreen Becomes Unresponsive :/

Hey
I am currently running 2.1 on my Samsung Galaxy S the only thing ive done to it is root it, so its running the normal firmware and I'm waiting till the end of september ti get the official 2.2 before I look at flashing something custom onto it, anyway...
I have an odd problem with the phone where the touchscreen part of the phone will become unresponsive for no real reason, sometimes playing a game, sometimes just sending a text or browsing the market. My actuall hard buttons like the homescreen or volume control still work during this and the only way to make my phone un-freeze is to press my power button once to turn the screen blank, then press it again and slide to unlock the phone, then it works fine.
No clue how to fix this... anyone got any ideas?
Thanks in advance..
Sounds like hardware issue. Get it fixed
Thanks for the response (know it was a while ago)
I've had the phone 2 months now in a contract with T-Mobile UK through Carphone Warehouse... Does anyone know what my return rights are? Talking to them later just want to know where I stand when asking for a replacement.
Thanks

hello, i have same issue. Did you fix this problem?
Thanks
This comes really long after. But did anyone find out the reason for this?
I've got an Galaxy S that works fine most of the time. But from time to time the screen will become unresponsive. If I press power button to lock the screen and unlock it again, it goes away. So it seems that it is a software problem.
Another peculiarity is that the keys on the Samsung keyboard are very inaccurate to respond to touch from time to time. Sometimes it is just impossible to hit a letter in the mid row and pressing "s" can put "wz" on the screen.
I was thinking to just put CM on it anyway. But it will void the guarantee in case it is a hardware problem. So I want to make sure that it is software related.
Did anyone manage to fix this either by returning the phone or removing TouchWiz. I am not living in the same country as I bought the phone. So returning it for a checkup will take some effort.
For what ever it is worth
I took the phone to an unofficial service center that flashed the phone with a brand new Android 2.3.3 (the phone came with 2.3.5). A downgrade, which normally isn't a very good deal. But the dead areas on the screen are gone. The phone is much more responsive and the keyboard is not acting funny anymore.
So... if you are experiencing the same. Try getting rid of the TouchWiz before you start taking the phone apart.
Good luck!
I get it occasionally but I've grown to live with it, mine tends to be the kernel recently flashed devils for 4.0.3 but after fiddling with volts mine stops.

[Q] Screen issue on Xperia Z

İ do have a weird issue on my phone and i don't know is it an hardware or software issue.
1.While surfing internet on some of browser's buttons appears grey lines.As you can see from screenshots it disappears if i restart the phone.

2.when i answer a call while the phone ringing even I swipe the green accept button phone continues to vibrating for an half second.
Is this issues related to a hardware or software problems ?
This is a new sample
Hard to tell, most likely a software issue? Doesn't seem to be on the same part of the screen.
Have you tried repairing it with Sony update service? Try that then tell us if it resolves the issue.

İ did repair by sony update service it didn't resolve the issue
It looks like graphical corruption.
If that was taken with the screenshot feature and a software repair has not fixed it, it could well be faulty hardware. (I would guess at either the GPU or Memory).
Does it tend to do it more, the more you use the phone? i.e. when it gets hotter/stressed.

I tried a few stock rom and it didn't help either.And I couldn't observe it why it's appearing because I didn't see it today, also restarting the phone doesn't help also.I don't know it has connection with it because I have . Dead pixel on the middle of screen
Take it back to the shop and ask for an exchange or repair. Gl

HTC One M7 Touchscreen Dead

Hi all,
Anyone else having any issues like this? I see this was a common problem on that HTC One X as well (thread for reference: http://forum.xda-developers.com/showthread.php?t=2010897 ). I haven't seen any reports of this and I searched the forums and the internet...maybe I've had bad luck because of the similar name, but I haven't heard anything official from XDA or otherwise
Occasionally, it seems that the middle area can work if there is enough static on the screen. Here is my screen map to show what I'm talking about:
UPDATE:
How strange. This issue started happening on Saturday, but on Monday when I was about to go down to T-Mobile to return the phone for a warranty repair, it suddenly fixed itself. I have full screen functionality. I didn't change any settings, didn't flash anything new, etc. The phone was never turned off (other than when I was testing if a restart or power cycle would fix it). I'll keep monitoring it in any case...

Exactly, I haven't heard before this similar problem... I think you are the first.
Have you installed a special app ?
Have you tried to reboot before to use it a another time ?
But I think that it's a problem with your touchscreen. So the best you can do, it's to send it back to HTC
This is definitely a digitizer defect. Only fix is to replace the glass/digitizer. Send it back to HTC as soon as possible because it will only get worse over time. I had the same problem with my one X

I have the same problem; RMA time it seems. I am a bit worried if they will accept it under warranty or not, because I unlocked the bootloader .

Did you find out if it can be replaced under warranty if you unlock your boot loader? I also have the exact same problem on mine the top part of my screen which has a completely bunked touch sensor it goes nuts if used touch anywhere near the top of the phone..
But like you I unlocked my boot loader and installed quite a few different roms thinking it would solve the problem… I am wondering if there is a way to relock the boot loader and make it look like it never happened? Although I doubt it because they probably have the information about the phone at HTC since they sent me the token to unlock it..
Well, apparently there isn't much you can do if you are on hboot 1.54 (like me), since you need to be s-off to erase the *tampered* flag if you just relock it will stay.
I didn't send it for repairs yet, but I will report when I do.
Hello guys,
i've got the same problem, my phone just started to act very wired, my top part of the display is not responsible, seems part of touchscreen is broken. Have you solved it somehow or you applied for warranty.
the same situation -bootloader unlocked and flashed different roms, I'm S ON, so can't flash RUU to see if it's software problem or HW
Did you brought it back to HTC? Since today im having the same problem.. Same for me, unlocked. Guess I'll have to pay

Yes I will report back when I flashed RUU. I'm pretty 100% this will not solve the problem but it's worth the try.
I'm also really struggling if I should it send back to HTC or not, I have this feeling they will flash my Hboot to 1.54 so newer customers can't get their hands on S-Off. A local telephone repair-dudey could fix my screen for 170 euro which is a pretty good deal.
I Sent HTC an e-mail with the current situation and still waiting for a reply, will report the whole story back

Okay I flashed RUU but with no avail. Im still having a line in my screen that doesnt work! I'm thinking of just letting it repair by the local telephone guy. HTC here in the netherlands work with an external company called Dynafix which will take about 3-4 weeks of time to repair it, and I'm also afraid that they will upgrade my hboot to 1.54 so I will lose the ability to s-off. (Not 100% sure, but just feeling it)
I hope you have enough information, we're both screwed without replacing a digitizer.. oh well, karma will strike back someday
They won't put you back to s-on, read in another thread that some phones ship with s-off and htc do not have any way of knowing who set the flag to off

HTC should replace your ones under warranty regardless of bootloader/soff. It is a physical hardware issue and has nothing to do with the software on the phone.

not good news, i was hoping that the problem might be fixed once RUU is flashed at least we know that repair center is the only option here
i would suggest to send the phone to HTC, better than to give it to someone to fix it, this phone is quite complicated when speaking about opening, but up to u and i think u will get a new phone if u send it to htc repair center... so no signs that the phone was opened etc.. up to u, the same with my phone, if i apply for warranty i will have to wait about 30 days, but for now no go without LOCKED and TEMPERED removed..
if i had to apply for warranty with tempered...no s off in upcoming few months, i will arrgue with HTC that screen HW itself doesn';t have anything with software, even if there would be status "hahaha htc" and not unlocked i will not pay for their crap more money
Well I have really no idea what happened but the phone decided to fix itself and I no longer have digitizer problems anymore.. So far its working (for over more then 8 hours already).
But yeah, you are right, it's probably better to bring it to HTC then a local repair shop when it get's broken again.
Well that's that, I really hope your phone kicks back to it's normal state aswell!! (I received an email regarding my issue and they said a factory reset would help, I doubt it though.. flashed a RUU and the problem was still there)
Same Problem ( is it HW or SW )
hello guys , i have the same problem as shown in the pic attached
i made HTC secret code and the Line Drawing test shows the problem well
, i made hard reset but still the same ,
i bought the phone from Amazon.com USA and now am in egypt
dont know if i can send it to HTC support
btw the problem time is unstable , sometimes working fine and other becoming weird any help ?
UPDATE : after contacting HTC support they replied to me with the below :
'' Thank you for your email regarding your HTC device. I apologize for the issues you have experienced with the device functionality, Mohamed.
There are a number of reasons that your device could be having this issue. It can be caused by an application, task killers, or software issues. To determine which one, we will need to put the phone in safe mode. Safe mode is a method that allows the device to run without non-essential applications.
Press and hold the power button until the power menu comes up then press and hold on the Power off option and pop up will come up with the option to reboot into safe mode.
After you put it in Safe Mode, try using it without third party applications for a at least 24 hours to see how the device works. If it does not have this issue, then it is one of your applications. Try adding them back one at a time to see which one is responsible.
If the issues still persist please contact HTC repairs: HTC RMA Center, 1-866-449-8358 8AM - 1AM ET 7 days a week. That way you can go through the repair process as it is a little complex and we would need to speak to you on the phone to setup the repair ticket.
If you have any other questions about your device please feel free to contact us via email at any time.''
i tried it but still the same , i think it is hardware issue :'(
Can anyone confirm whether this S-OFF software can re-lock the bootloader and make it look like the warranty is still intact ? I need to send my phone back to HTC for a new digitizer stat
Yeah it's possible. Here's a guide for you: http://www.htc1guru.com/guides/return-stock-guide/

I9000 back button is stucked ON

After I have changed the screen (I bought one from ebay, completed with menu button in) the back button is stucked on most of the time. There are times when it's working well and times when it's stucked ON. So I can't use my phone at all. It might be a hardware problem? I tried cm 9, cm 10 and cm10.1. The same. Thinking of taking menu, back and central button from broken screen and try one more... Any solution, please?
It seems I will break another screen for removing home button.I was wrong! Any help please?
Sent from my GT-I9000 using xda app-developers app
Sounds like a hardware problem, could be from replacing your screen. So you might want to go get the screen checked out by someone just to see whether there's a dodgy connecion or anything.
Until then, use LMT Launcher or Pie Controls (same thing really) if they're built into the rom (like many have) to navigate your phone. Not exactly ideal, I know, but that's one of your only options if you don't want to get the hardware checked.

z1 shut off probblem

I have a carrier bell C6906, anyone else having problems with .257 firmware it randomly shuts off and I had to hold power key to turn back on again, it seems does that randomly everyday when the phone is on standby (unplug), and with .534 firmware the phone randomly shut off (not as much as .257) and it doesn't turn back on with power button, I had to hold down vol up + power key to boot the phone back up, should I be worry about this problem or its firmware issue, should I bring back for warranty? and the viewing angle is garbage I just tilt 30 degrees the colors are washed out, but no yellow tint.

Bring it in to get replaced. The sooner the better. There's no point in dealing with an issues that's been there since the time you got the phone. I've had mine for 3 weeks now and have had no problems.

I called bell tech support they advice me to do a DOA replacement in bell store, since the phone is less than 30 days old, sucks my phone is only 17 days old and they wont replace it with a black one because its passed 14 days policy even though I got a defective unit at purchase, they have to replace it with same color white as my previous one
I have no problem like that either,

I'm on EE in the UK but running monx rom. My phone has rebooted itself once per day, my friends Z1 which is also in the UK on three has this same issue, I think it's just bad software on Sony's part, probably will be fixed in the future.
Saying that i've only had the phone since yesterday and it's not very welcoming for something like this to happen.

custom rom/bootloader unlock might be the cause of this problem? maybe?

Nope the phone did it before it was rooted, also my friends is not rooted and has not been tampered with, as i said i think it's a Sony thing, hopefully i'm wrong.
BH900LM, the screen is better . Don't notice the dots as much previous one, not sure if they gonna blame me for damage yet have to go and see, this display is way better than previous the white is so white compared last product and the viewing angle is improved a little, I wish this device didn't have a tiny chip at the back I would've kept this. I hope my next replacement is as good as this one minus the broken corner hah

I'm stock, not rooted, .534 and getting 1-2 shutdowns a day. I have to pop open the sim card cover and press and hold the little red button in order to get my phone to power off then I can power it on normally. This is getting ridiculous.

I have already carried out the repair procedure in pc companion, but It doesn't downgrade s/w.
And the other procedure you linked also say I need to downgrade if mine has latest s/w, but as I say, I have no previous stock bell ftf file. The only ftf file I can get is Rogers stock.
Did you do with Rogers stock?
