[Q] Q-touch problem - Xperia SP Q&A, Help & Troubleshooting

hey guys, I bought my xperia sp c5302 2 weeks back and m loving this device.Recently,I have been facing a strange problem in which the touchscreen of my device fails to register my touch 70 percent times when kept on a horizontal surface and 30 percent times when holding it normally in my hands.I have tried many caliberation apps non of which worked.Although, I did notice that the problem gets fixed completely if i turn on the glove mode followed by a reboot.the problem re-appears after some hours when the glove mode is disabled.This is quite a common problem and I would like to know if any of you is facing this issue.This appears as a software problem to me but still, your opinions are welcomed.
Should I go to the service centre or if there is anything else that I can try.
Thankyou

Hi. You should try fix touch by 'Android Tweaker' - Tick 'Increase overall Touch responsiveness'. So why dont you keep gloves mode on, i have always on and its ok, no battery drain, nothing.

No idea... I bought my phone at the earlier earlier batch, where it is pack in bubblewrap... LOL!
Anyway, at 2.2.2, still same problem. Doesn't want to get custom rom, as after my exam, i'm going down to LG and get some servicing or shyt out from them...
The problem exist especially when you are charging. It occur also when you put your phone to sleep while running on GPS. Very fedup with it.
It is categorized in Freeze and Reboot Problem
It's the first stage of that problem, if you continue using it, you will suffer the reboot problem

solution to some bsod models. Tested, working!
Many p990 bsod models have faulty soldering of some sort. A solution which have worked for many is to simply plug in your charger. When your phone goes to sleep and doesnt wake up when you hit the power button, just leave it be for 12+ hours. Place your phone on something soft as well, like your bed. This will heat up the device and fix the faulty soldering. If it does not work, try longer period of charging. Good luck. (I will take no responsibility if this does not work as planned)
This was tried on a bsod model which went to unresponsive sleep every 5-30 minutes. After this procedure it was faultless

I've had my LG for quite some time now and I still trying to figure it out. So, if you're patient enough, please, just bare with me for a while as I explain what I've tried so far what what were the results.
A lot of people complains about this phone... unstable, crashes, reboots, BSOD, etc...
The first problem I had, came with the stock ROM... after a while the Wi-Fi just stopped working and it would display "Error..." as a message. The only solution was to reboot. 3 or 4 days after I had bought it, this was already killing me... so I started trying other ROMs but all seemed to suffer from some sort of problem except for one (see phone info below), which I've been running since June and I find it impeccably stable I can basically keep my phone running for as long as I want, as long as the battery doesn't run out (obviously), which brings me to a second point... battery drain!!
The battery drain was the only problem I didn't manage to find a solution for... and after a certain while, even though my phone was stable, having to charge my phone every single day was becoming very annoying.
Since I live in a different country than my GSM operator, it doesn't come as a news flash that network look-up has a big impact on the battery life, specially because I live close enough to the border to be able to keep the signal but in some parts of my house the signal is lost forcing the phone to search for a new network, which sometimes it finds (roaming) and sometimes it comes back to the original network and so on... However, what I find, unarguably, to have the biggest impact on the battery is having the Wi-fi enabled when there's no available network, it's just huge, it can suck up the battery in a few hours...
So, I decided to try some of those power management apps such as Locale, Green Power and some other, in order to minimize these problems, but curiously, they all caused the same problem... BSOD within a matter of minutes. I installed the app, configured it, waited for the phone to go into sleep and puff... it was gone. The only way out of it was removing the battery. I uninstalled the app, and the phone was stable again... this happened with every single app of the kind, that I have tried.
At the moment my phone is as stable as it gets but if I don't pay it enough attention, the battery dies in a blink of an eye.

[Q] Galaxy Note GT-N7000 crashing regurlaly how to find out the culprit?

My Note has started crashing regurlaly, I have had it since release and have a lot of software on it. I am not sure when it started happening but it is definatley getting worse as time goes on.
Is there any log file or event browser that can be installed to tell me what is causing the problem?
When I say crashing I mean literally crashing dead not a force close. I either find it in my pocket turned off and then have to hold the power button for an age to turn it on or sometimes it is sat on the desk and I suddenly hear the noise it makes when it re boots.
Any suggestions for finding out what the problem is that don't involve uninstalling software until the problem goes away?!
Thanks
Have you tried better battery stats? It gives a list of processes that have been running.
Definitely strange - do you have an anti-virus program you can run to see if it can help?
That sounds like a Sod (Sleep of Death) issue that's been reported many times b0t with no definitive solution of yet..
Some said changing modem helped, others with changing kernel or even ROM but no consistent solution across all users
Try to fix permissions through advenced menu in recovery but am afraid there is not much I can help with

this is driving me nuts. The phone is unusable.... is there no possible solution??
At this point I will try anything. It crashed during the night on Thursday, didn't restart and so there was no alarm and I was late for work!
Please post your current configuration Kernel, Anti Virus program if any, undervolting, overclocking ?
By any chance are you using easy task killer... if you are just change the auto optimize to nothing - I did that and it stopped sleeping...if your problem is persisting then you could just do a factory reset and use default settings...

My note recently started crashing as well, whenever i turn on my mobile data plan or the wifi it will crash right away
However this is ironic because when ever i put my mobile in charging mood than i have no problems at all.
So im thinking ,is this the battery problem or the software problem?

If the meter say less than 1850mAh in full charge than u need a new battery.

Touch screen going CRAZY

I think I have the weirdest problem with my Sensation XL.
It works fine and sometimes, when I unlock it, the touch screen goes into super frenzy mode and starts doing things on its own. When it's stuck in that mode, I cannot use it, and it clicks buttons around randomly and very fast.
I have seen it open my messages, swipe a long gibberish text and send it (!) or this morning it just opened contacts and deleted one!
I am pretty sure it's all in random because on the keyboard I can see it swiping very randomly around the screen and in a very fast speed.
What on earth is this and how do I stop it? It almost looks like a virus or some sort of spyware but I checked and see nothing malicious installed.
The phone is about 8 months old and is not rooted. Latest firmware installed.(4.0.3 Android version).
The crazy behaviour did not coincide with any updates in software. Just started 3 weeks ago randomly and happened maybe 5 times till now.
The only way to stop your phone going mad and doing something you don't want it to do is to quickly rip the battery off, because you are unable to restart it from the touch screen.
It only happens after you unlock it, not while you're using it and I noticed it happens after a long period of inactivity.
Has anyone had that? Any help is very appreciated!
Thank you

Lock the screen and open it again. If this doesn't stop it could be a Hardware problem
I also had some problems like this on the original firmware, but rarely, it got fixed when i flashed Incredibly Cool Sense v3. You should lock the screen not to rip the battery off, as it's faster and it should work

I don't think it's a hardware issue cause the phone works well most of the time. If it was hardware the problem would be permanent, not intermittent and especially so occasional.
Must be something software related, I did add a lot of games to the phone recently but the problem happens even when these processes aren't running in the background which is puzzling.
Locking and unlocking the screen postpones the problem, it doesn't solve it. As soon as the screen is unlocked, it immediately goes crazy again.
I can only solve it by pulling the battery out, and FAST, before it sends crazy messages to my contacts

Welcome to the club. I had that same issue. But after a hard reset everything is fine with mine.
I assume that there was an app causing all that. If after a hard reset still does that you should send it for repair
If you have a screen protector its can be a main reason for this. To stop this behavior you can use power button and wake up it again. Some htc devices have the problem with multi touch screen
Issues of production. Clear the screen products with some alcohol and see than.

I don't have a screen protector actually and the screen is usually clean.
Must be some app, I wonder there was some way to find out which without having to do a hard reset and lose everything

You can't! There is no way you can find out which one is causing that. Maybe it's some update from something that is causing the freezing.
Last night i did notice something else though. My battery was almost empty and i took my gf charger. She has S2 and after i charged my phone it has started to act strange......... Even today after i pluged the phone to install something from the PC it didn't even notice that i have connected it to the PC. Took me about 20 min in/out to get it running I clean the usb slot every week so it is not a dirt issue....
it happens with me when there's water on the screen

Be careful from contiouas pressure on screen it may drive it to behave strangely .
Try to use lock code before putting the phone into pocket
Sent from my HTC Runnymede using xda app-developers app
Definitely on to something.
It has happened a few times when it was drizzling and there were tiny droplets on the screen (not proper rain).
It started acting up when I was swiping the screen against the tiny droplets. After locking it, it would stop responding...
Most of the times I find it either non reponsive or acting weird after I take it out of my back pocket and try to unlock it.
Maybe being in my pocket, even locked, affects it somehow.
Is it easy to put another Rom? Do I lose all my apps?

sorry to bump an old thread.
I have this problem on a bashed up screen. however... I don't think it can be hardware because if I hard reset its then OK on the next boot...
we need to learn more about touchscreens - how are they calibrated? I think it is reset on boot and also on each lock
Its the LCD ribbon touching the metal housing, short circuiting the screen, easy fix with a piece of tape over the ribbon
Edit
Also, once the phone heats up resistance builds up with it causing the issue

Xperia Z vibration problem (experiment was done and detailed explainations given)

I realized that my Xperia Z's vibrator will stop working after an "intense" work or overheated...
for example, i turned on the "vibrate on touch" option, and then keep pressing any key (let's say the Home virtual key), i can feel that the vibration strength will get weaker and weaker, and finally stops.
at this point, the vibrator wouldn't work, no matter how. Neither in Service Test, switching on/off phone (i believe these cannot be altered by the user)
Then if I leave the phone there for a while, the vibrator will start working again, and if i repeat the experiment (pressing Home key), the number of times the phone would vibrate is fewer ( e.g. the phone vibrated ~30 times before stopped working at the first test, then it stopped working after ~10 times at the second test).
Interestingly, the vibrator would work again immediately if i shaked the phone (even straight after it was "dead"), but the length of time it came back "alive" is even shorter.
And it seems that the vibrator functionality also depends on how i hold the phone... by making it flat (screen facing sky), the vibrator seems to work better and longer.
I also found that the vibrator would stop working when the phone is being charged, but i am not so sure if it was caused by charging or the heating up of the phone as it went quite warm when charing. When I unplugged the phone, the vibrator didn't came back alive immediately, so I washed it with cold water (hey it's water proof !) and the vibrator worked again!
I have tried Factory Reset, and re-installing the firmware via Update Service but the phenomenon still exists.
It's kind of weird, and i hope some technitians could give reasons of this behavior. To me it's like the vibrator needs some time to settle down, the damping isn't efficient. Or, the current is too high so it cuts the flow to the vibrator for safety reason?
maybe some xda developers could check the codes and see how the vibrator behaves?
I hope there isn't a faulty of my phone, I really don't want to send it to the service centre for a body-check....
Thanks

I'm facing the same problem, the vibration works occasionally , and there is a lot of people with this problem, I will wait for now waiting a fix, some people here confirm that the problem disappeared after 2 days of use. How old is yours?
Sent from my C6602 using xda app-developers app
new update:
i did some more tests. and i found that:
1. vibrator stopped working during charging once the phone's temperature rised above 30 degrees (actually vibration kept working for a few times before completely dead). and even it then cooled down to below 30 degrees, the vibrator was still dead (still in charging, cable plugged in). and vibrator came back alive immediately when unplugged (at this moment the temperature was 28 degrees). but if the temperature went above 30, unplugging wouldn't bring the vibrator back to life, and i had to leave the phone there for a while.
2. at any temperature, continuously pressing the soft keys (with haptic feedback switch on) VERY quickly (i mean like pressing it 10 times in one second that quickly), or just go to Service Test -> vibrator and set the vibration time to something LONG (e.g. 90000), the vibrator worked for a while then died. then if i gave it a break (~10 mins) of gave it a shake, vibrator came back alive again.
3. no matter what caused the death of vibrator (point 1 or 2), if I could cool the phone down very rapidly, i.e. I put it in cold water, the vibrator would come back alive.
4. the cooler the phone is, the stronger and longer working time of the vibration (as in point 2)
so i guess it's the temperature that causing this problem, seems like a hardware issue (because my X10 doesn't behave like this), probably the circuit isn't connected properly.

mine is nearly a month old. i didn't notice this problem until a few days ago. so i cannot comfirm if it was already like this when i bought it.
i think we should gather all the complaining posts of this issue and send it to Sony (at least before we send it to service centre for repairing).

What firmware are you on? Yeah, it sucks to have issues on a brand new handset especially at this price! Try to check if there's update available. I'm currently on .531 and haven't had any SOD so far.

If optimised backlight is switched off then it seems to happen anytime to change anything to do with brightness.

I have experienced this bug on multiple occasions as well since I first got the phone. The phone randomly goes to sleep but the backlight stays on. Then I am not able to unlock the phone by pressing the power button and I need to hard-reset it (vol up+power) to bring it back to life.
For me it happened once or twice already even with Optimized backlight checked
happened to me when i was trying to share a dinosaur effect photo in the camera app
I actually experienced the bug on a few occasions right now and can't see a pattern. It doesn't matter if I have optimized lightening on or other functions it will just randomly happen on different occasions.
I have just flashed the newest .534 firmware and soon after the same thing happaned again so I guess it has not been fixed as of yet.

Arrgh! I just experienced this screen bug . And this is for the first time in last 4 days of owning the phone. It occurred while the phone was lying on the table (battery 9%) & I picked it up to make a call, but the screen won't light up. Had to hard boot using vol up + power button. Have not touched the optimised backlight option (still checked). Hope sony fixes this asap!
DAMN ! I'm on 14.1.G.1.534 and I just got this ! it hasn't even been 24 hours yet since I bought this phone. terribly disappointed.this could be such a great device. hope it doesn't keep happening - Sony Xperia Z1 C9602 - wtf sony.

I've had this happen twice since been on 534 firmware and had to use the red button to force the device down. Very frustrating but I think Sony will sort it and all will be good.

i have just about had enough of sony to be honest, i cant believe this is the third sony device in a row where there is something wrong with it, i bought the xperia z tablet, the touch screen was way to sensitive until an update fixed it, i bought the z ultra and returned it because of the sod, and now this, i turned off my phone last night as i didnt want to be interrupted, try to turn it on this morning, the sony screen comes up, then a blank gray screen, rebooted it a few times with no luck, the last time i just left it and eventually it booted to the home screen
and just now, i opened the camera app, just get a black screen, open snapchat to see if the camera works there, nope, it says error with the camera please restart device, so i do, only to experience the sod again...
honestly, with my experiences with xperia, i have had enough, i can put up with mediocrity only for a bit, if i keep on putting up with this crap, it makes me look like a fool
stuff you sony
Same here, terrible bug. Screen is actually there, but backlight won't turn on. I have to position phones screen towards the light source in order to go to the screen settings to uncheck optimised backlight option. If it is checked I have to uncheck it to get backlight to turn on and vice versa. Sony, fix that as soon as possible 'cause you got some pissed Xperia Z1 users here!
Im with a uk model and still on the original 518 version, and I've been playing it around for several days but no SOD issue
same issue with z1 C6903
i using z1 with .534 also facing same problem for past a week. it is dead when phone calls in. have to hard reset too. come on sony, this is issue is not new. we need a solution.
mind you, the phone is not launch in my country but i manage to use it.
Hi All,
I am from India and using Z1 (C6902) and its been 3 days since using my phone and thank god, no SOD at all...
maybe since mine is C6902 thats why ... i dont know but no SOD here till now
I have noticed this bug after i rooted my z1. (root via kingo tool), before it was working ok.
So when power off button pressed, screen still active...
after some tries, i have disabled auto-brightness check box. its now more or less working.

You're buying products that are relatively new (except the Tablet Z) and expect no bugs at all? LOL I think you need to step back and look at the whole picture. To be honest Sony releases updates in a fast and consistent manner so you should be happy that do this. Even the Nexus devices have their share of bugs and always see people react like bugs do not exist. There will always be bugs and what you want from a manufacturer is to release fixes.
Hi, me too having this bug. I had this SOD twice since last 7 days. Had to do a hard reset both the times. Waiting for sony to fix it. I think its the jelly bean bug and not the Sony's firmware's bug but can be fixed, i think.
I am from india and on the latest fw. 534.
Please let me know if there is any solution to this available in the market. Thanks in advance.
