To keep things simple, I had a cracked screen on the Ultra which was replaced last week. However now the phone screen is slow and unresponsive after about a minute of use (fast & like new after right turning on however).
Ive tried the mod tweak found here http://forum.xda-developers.com/showthread.php?t=2522657
As well as the thermal screen calibration here http://forum.xda-developers.com/showthread.php?t=2470070
There is no change with either mode. Cleaning with alcohol only works for a few minutes, and yes Ive removed the ASF for no change.
It should be noted that when booted at first minute or two, the touch inferface is quick and brilliant. After a minute or so it gets slower and remains so. Typing a text is a gruelling affair at that point,
Ran 4.3 android and updated to 4.4.4 and also no change in performance.
Does anyone have any ideas/ tips or pointers?
HELP!?!
An app with a memory leak?
Looks quite normal. RAM 1.1GB used; 600MB free.
Unless thats not what were talking about?
EDIT: might be up to something. using advanced kill on Go taskmanager EX and its seemed to do improve the situation in the short term. Will keep testing
Well got about that far thus far. The advanced kill works sometimes, but none of the apps look out of whack (from my basic knowledge anyhow)
Any help/ links in diagnosing a memory leak would be very appreciated.
Don't suppose you've got the Google now launcher? I had to uninstall as they introduced a memory leak in the last update.
Un updated it just in case.
Its tough as even watchdog lite isint detecting much. com.google.android.gms:snet at startup took 22% CPu but otherwise its steady.
Grr jezz I even did a factory reset to 4.4.4 and its still there. Would trying a custom rom help?
Well as an update manage to completely wipe and reinstall the OS. No change in performance however
Does anyone know if a faulty screen install could be to blame for this?

Could well be, but i find it strange that it acts normal again after a reboot? That alone indicates that it's something wrong with the software. I still hold a finger on a process gone wild. Do you have Recovery installed? If yes, re-flash the ROM or flash something else and see if that solves it. I would personally flash a stock ROM and flash it with Flashtool so you don't have to root or void any warranties, and it'll be the simplest thing to do in case the screen is still acting weird after flash, and you want to get it checked out again (since it most certainly will be a hardware issue at that point).
So, fire up Flashtool, download a complete stock ROM (TFT), flash it, test it. Is it working fine now? Sweet. Keep using the ROM. Is it still the same thing? Contact the repair center again and tell them what's up and please do tell them that you've already done a factory reset, since that's the first thing they'll do themselves. Do not tell them about Flashtool or any other hacks or tweaks. They'll probably blame you if they think that you're an XDA user. "Oh, so you've been playing with it, and you bricked it and wanna fix it for free, bla bla".
Ask if they can open the device again and check that everything is fine and that you haven't received a faulty panel.
Ive actually did a complete tft flash of the original xperia ultra software. No change whatsoever vs previous state.
Im increasingly suspecting a hardware issue. Could it be a poorly plugged in cable? Its random chugging/ smooth response is completely confusing...

Did you flash the exact same FTF that you've always used, or did you flash one from a different region? I would try the GPe ROM if i were you, just to be sure, but don't bother doing it if you're not rooted and ready to flash. Yes it can easily be a hardware issue, and you should probably contact Sony or your nearest service center.
As an update I tried installing a fresh tft flash of a different build but same issue.
Notably noticed that the notification light on the screen is not working at all, so currently looks like a hardware issue. Will keep updated for reference & visit a repair centre

Hey!
I've noticed that in a few applications (or settings) i have issues with my touch-input. This is e.g when changing the default ringtone i can't just tap "ok" but have to press the "ok" button from the side with my whole finger, otherwise it won't be regocnised. Sometimes when using the keyboard, the buttons on the right side are very hard to use. That would be the "p" "l" and "backspace". Have anyone else had this problem? The weird thing is that sometimes it works perfect, but sometimes it's just a pain in the ass to get things done?
I think sometimes the touch screen can just not work properly, just luck of the draw I guess.
Has yours always been like this or is it a recent change? I am assuming its always been like this.
if it has then its a hardware failure (most likely) and will need to go back under warranty for repair.
If its a new change, then what has happened to cause it? Could just be a new rom or something causing the calibration to be off.
It hasn't always been like this. Lately it has begun to screw with me. And i don't think it has anything to do with luck, since it's always the same programs that do this. e.g. changing ringtone, accepting the google maps license on first run etc.
One could think this is a hardware failure, that's what i thought at first, but the strange thing is, that the same "area" on the screen works prefectly in other applications. I've tried several roms, but they all act like this. Perhaps I should install the stock rom and try with that.
I have a similar issue, and even more, sometimes once I am pressing the screen, the keys are starting to "dance" like the hero is trying to think which button to choose, by itself, and I am watching it, and smiling :-(
I've had it since SenseHero 1.5 and others as well. I just reinstalled the official htc rom and calibrated again the screen... but I am afraid the issue is still there, though less frequent...
Next week at the doorsteps of Orange I guess
Possibly is lag related?
Maybe the phones memory management is not working very well on the ROM you have installed and is causing large amounts of lag that the phone is interpreting touches (or not touches).

Possible, But with all the speed tweaks, task killer and stuff, maybe even the overclock widget that I started to use only after this issue appeared... don't know, have no idea how to solve it.
Now it is like beginning, with official htc rom, no additional apps installed neither contacts, and still, I have this issue.
Suggestion?
Got the exact same problem.
Almost exclusively buttons on the bottom of the screen and as you already said the right part of the keyboard (especially the goddamn backspace drives me nuts sometimes!).
It hasn't always been like this, started somewhen after flashing more than just Modaco I think.. And the severity varies a lot, sometimes I got barely any issues and then again I can't even finish an sms. Unnerving.
At htcpedia someone who obviously has the same problem pm'ed me his solution:
Your Problem with Screen
I had to wipe everything of.... installed the WWE original ROM, then re-root the phone and now working with Modacco 3.1, seems to be working ok now....think the problem was with LOX latest ROM.
Click to expand...
Click to collapse
I think - not sure - it startet with some lox rom for me too. Do you remember which Rom you were using when this first occured?
Well anyway, might give it a try.
I haven't tried it yet for 3 reasons:
1 - the link for the german version of the original firmware is down
2 - i don't have a windows computer, so the .exe is pretty much useless for me
3 - I'm way too lazy as currently it's not that bad
same problem
hye there, I seldomly post here..
But i got the same problem before... keyboard dances, hard to click OK... could not finish a sms without swearing F*** F***..
yep, its a hardware problem.. maybe its bcoz of the shape of the hero making its touch screen easily damage.. Not sure though..
flashed so many roms, to try to fix this problem.. thought it was a software issue.. but.... nothing..
went to HTC care centre.. and changed the touch screen (warranty, had to revert everything to stock) and now...
Good as New with Villain 3.4
hope this helps...
Oh thx guys. "Happy" not to be the only one with this issue. For starters I'll try the solution with the original rom. I think I still have some version of windows installed on one of my harddrives. If it don't work I'll have the screen changed. I'll report soon.

When you revert to stock Rom, do you need to reinstall a stock recovery as well? or is it automatic? because I reverted and when I try to boot into recovery with "power + home" I get a kind of error: the symbol of a triangle with an exclamation mark in it, and a phone symbol lies down beneath it.
Is there another way to go into recovery? or is it not installed actually? (I went back to the official RUU from htc site).
Thanks for the help.
Ok, I've just tried the solution with the stock rom. As a matter of fact, it does fix the keyboard-issues. However, some of the other random touch-input-issues still persist. I can't really see how this could be hardwarebased, since the same area on the screen works in other applications just fine.
The official rom from HTC completly restores your phone as it was when you got it. You'll have to install your custom recovery again, as you did the first time.
I had a similar issue.
A fix for this: VillainROM6.1-Full-signed.
Now, keyboard its ok.
Try it.
For about 4 days now my screen has been acting up and giving me quite the annoyance. It initially started while i was on Deck's "gbsense-e3d-deck [1.0]" ROM. I wiped cache and dalvik then re flashed the ROM twice but the screen kept malfunctioning. I was forced to perform a factory reset and re flash a new downloaded file of the same ROM which fixed nothing. I wanted to see if it was a ROM specific issue so i flashed CyanogenMod 7 VALPHA3 and the issue was still present but to a much less annoying degree. Now it seems as if my device doesnt register touch around the midsection. That makes me unable to select anything that may be in that area. I have tried multiple multitouch apps and testers to "diagnose" what is going on with my touch screen, but all i can gather is that my screen might be ****ed. The phone works flawlessly excluding the touch screen's unresponsive zone, so i don't know whether it's a hardware or software issue. Any insight concerning this matter is welcomed, Thanks.
I have attached a video demonstrating my screen while using the app "multitouch paint"

Could it be a ground issue? Try holding the phone in your hand and see if it still does it. I remember my OG Evo having a similar problem when I laid it on something non conductive.

It occurs both while in hand or on a surface. An example is if i pull down the notification bar, depending what hits the affected zone, i'm unable to select it. I used SBM quite often and now when drawing for example a straight line up it would look like this _____________ __________ (vertically of course) the gap being my speculated affected area but much wider.

Is it possible that both of the roms you tested are using the same kernel? I would swap out the kernel with the stock one just in case. At least it'll rule it out lol.

I'd take it one step further and return completely to stock, if it STILL does it, then I would guess it's a problem with the digitizer and you would either have to buy a replacement one, or take it to Sprint. If you don't have TEP then HTC's warranty should suffice.
Possibly related?
http://forum.xda-developers.com/showthread.php?t=1267124
It looks similar to this issue, but you are getting it with a single touch instead of with a multitouch. I get EXACTLY the same thing if I use a second tap while drawing a line. Try "multitouch visualizer 2" from the market and see if it registers one tap that is on all the time or if you can actually get the full 4 touches at once. I doubt it will be insighful, but it can't hurt--and if you have an "always on" (perhaps in the button area below the screen) then you know the digitizer is bad.
If it is the same issue, try restarting and give it time. Mine has gone from happening often to happening about 1% of the time. It is software and can be "corrected" by either time or a restart. It is WORST on the first boot after flashing something (even JUST a stock kernel). I have absolutely no idea why.
Good luck. I hate this junk. My Evo 4G never had this sort of glitchy garbage, but, whatever it is, it is likely due to HTC's glitchy kernel!

My friend us having the exact same issue. If you figure anything out, please let us/me know.
Sent by my Supercharged dual core from the 3rd Dimension
I would also like to know whats going on.. I have two evo's 3d and my friend was telling me that he is having issue with the touchscreen he is still on stock... and my was rooted the same day I got it and has no issues.. He mentioned that the same area mentioned in this thread is the are affected in his phone... could this be cause by the screen digitizer??
Ignore this... Thought I found what my issue was... But wasn't the case
I had the same problem but it only seemed to be in one horizontal strip of my screen. Im not sure what caused it maybe its from me dropping it or what. I also did try to flash other roms and kernals but still no fix so i said to myself im going to put it back to stock and take it to sprint. There they looked it for about 2 minutes and deemed it was a hardware issue. The guy asked if i had a warranty. Two days later i received a refurbished phone.
So in all revert it back to stock... search on htcevohacks . com
Take it back to sprint and show them your problem. They should also deem it as a hardware issue and send you a replacement

Hi,
This is my first post so I do not know if it is in the right section.
I have an Android Phone (ZTE KIS V788 – Full spec: gsmarena.com /zte_kis_v788-4586.php)
It runs Android Gingerbread 2.3.6
It keeps turning off and restarts, it is basically not usable anymore.
What can I do to fix it?
And is there any way to update its software manually? (It has 256MB RAM, and 800MHz CPU)
Thanks!

Your issue is the device. No matter what you do to it, it will still act up. The issue is that the device doesn't even have enough ram to run the os properly. 256 mb of ram is just not gonna cut it.

I bet over the last month you have used it right? Meaning new apps, filling up database files in info? Phones like that are ok at best if left completely stock and maybe an app or two but they all sooner or later suffer the same thing. Mainly as they dont use an Official release version of android. Best advise I can give you is to keep it as clean stock as possible, Use cloud storage for pics and what not so you wont have them eating up space on the device.
You can get out of the soft bricked phase by try rebooting in fastboot menu. If that doesn't work you can try flashing the phones original files which will reset everything on your phone. Though, I recommend getting a new phone because, your still running gingerbread. That is an extremely old os as most newer devices are running lollipop and kitkat. If you don't plan on spending a lot of money on a phone, there are plenty of cheap phones out there. If you do manage to get out the bootloop than I wouldn't run any newer apps on it, as it will crash the phone.

I have always kept it stock, only installed Facebook and whatsapp.
This is a very weird issue, as the phone behaves normal when charging and does not randomly turn off.
I downloaded an app that checks the battery health, and it says that the battery is good.
I also noticed that when the phone turns off and I switch it back on then the battery is completely drained – for example I have it at 100% charge and after the random restart it shows only 9%.

To flash the phones original files, you will need to look up a video either on YouTube or find another website with informative directions. Basically, you will need fastboot files and roms/ img files to revert your phone. You will need a computer and usb cable for this. Go to YouTube and search how to fix a bootloop or how to fix a bricked/soft bricked phone. Best of luck.

Sounds like your battery is one of two things. 1. Its going bad. (Many reasons why the app is tell you its fine, Thats 2) 2. The battery is a fake and there is software that was changed to hide this. A common practice in some places in the world. The reason it is only now failing "could" be that it is starting to die but the software is still set to show you its good.
The fact that it works fine when it is plugged in would support those theories.
You could try reflashing the files as suggested, but do yourself a favor and DO NOT use some youtube video. At least not before reading up. The issue with youtube videos is that if something goes wrong then you are stuck even worse with no idea what to do. Then you will find yourself right back here.
I am experiencing a big enough lag on my phone that I bought last week used from someone. It had 4.4.4 when I bought it and the phone would lag alot so did a factory reset and stiil the same, I did the 5.0.2 update with pc compagnion, everything went good but tha lag is still present. If I turn off the phone and turn it back on its all good for about 3 to 5 minutes and then again the lag comes back.
The only way I can get rid of the lag is with rom toolbox, cpu control, I set governor to performance then the lag is gone but I find the battery drains quicker when set to performance, and dont want toake the cpu run too hard either.
Could my phone has a hardware problem. Please help me
Have you tried to restore via PC companion or flashtool? Maybe that would solve it

I did install 5.0.2 with pc companion and the lag is still present but i can try to restore with pc companion and hope it will do the trick because I really like this phone. Thanks for the tip
Tried restore and the lag is still present. I dont know what else to do, probably a hardware problem since the lag is in 4.3, 4.4.4, 5.0.2. The owner who had it before me changed the screen on it maybe it could be related but dont know what else to do. Any advice would be really appreciated.
Could you describe the lag a bit more. I've been seeing a longer and longer lag on my C6806 but I thought it was due to the number of apps I have installed.
I did have the screen replaced by a Sony repair center contractor in Canada. I was not impressed by their service. They took 2 months to fix my phone! The new screen isn't completely flat and they put a scratch on the back panel from the back side.
I can see the lag getting worse as I use the phone continuously and it warms up. You can feel the back top centerish area getting hot as it's going. Sometimes it will reset when it gets too hot.
I wonder if they didn't add thermal paste to the processor or something when it was being repaired.
Hi,
My Z4 just asked to update the ROM, and afterwards, the screen has areas that are no longer touch sensitive.
Is anyone else experiencing this issue?
Thanks for any ideas!
Jim
Have you tried rebooting, then opening the Diagnostics app and running the touch screen test? If there are still dead spots showing in the test, you might want to flag it to Sony support.
I'm not certain if it's a software or hardware issue, but I have found both pre and post-update, that the touchscreen occasionally becomes less responsive, to the point that trying to use a drag gesture doesn't work without the touch dropping out. This happens every couple of days, and I suspect it's to do with throttling as it coincides with very sluggish performance. Seems to resolve itself when left for a few minutes, or a reboot.
Yes! I thought it was just me. I have a tempered glass screen protector and removed it to confirm whether it was causing the issues. Also ran the diagnostics which ran just fine.
It seems to be perfectly fine after a reboot and then the longer you go the worse it gets.
Hoping that this is fixed in the 5.1.1 update whenever that happens.
The conditions that this occurs does seem extremely sporadic. After playing Star Wars Uprising for ~45 minutes yesterday morning, the touch screen failed to recognise any swipes or taps, to the point I had to force a restart with the power button to exit the game. After leaving the Z4 for 15 minutes, no issues at all.
Last night I managed to play the same game for over 90 minutes, and today for another 90 minutes with no problems at all.
I'm starting to think that it could be performance throttling, alternatively I have noticed the screen getting particularly warm above where the SOC sits. Could this temperature be affecting the screen sensitivity? Using CPU-Z I have found some of the sensors reporting around 70C, battery around 35C, though this is after running intensive games. I'm unsure if the upper temperature is normal for this type of chip or not.

I have the very same problem:
Tempered glass from IVSO and the original case from Sony.
Since the update the touchscreen is VERY unresponsive.
I removed the case (!) and it got better (seriously, WTF?).
Does it mean to remove the tempered glass will solve the problem?
But it was fine before upgrade to 251. Sony sucks...
我從使用 Tapatalk 的 SGP771 發送
I reset to factory settings, and that may have cleared it up... but I'm not positive.
I'll update this thread when I play with it some more.
Did anyone have success with removing the screen protector?
OK - I can confirm that a factory reset after the upgrade does not solve the problem. My tablet cannot pass the touch screen diagnostic.

I removed the case, not the screen protector.
But some issues are left, so i hope for the next FW-Update...
An update:
I reached out to Sony's support group. They suggested downloading the PC companion app and having it reflash the .251. This does a factory reset.
This made the touchscreen response significantly worse.
My next step is to see if they will let me downgrade to the previous release, because the tablet was working flawlessly on that release.
Sony support says you can't downgrade to the previous rom. I found flashtool, but can't find the old rom to flash onto the tablet. Still looking...
Noticed the same thing after the update.. Hoping for a fix soon as it was flawless before the update.
Now simply browsing is annoying because it either misses swipes or registers them as longer swipes, causing the page I'm trying to read to scroll down super fast as if I flicked it when I actually scrolled slowly. :crying:
There is no update coming. Sony does not acknowledge that the problem exists.
Need more people to post on Sony offical forum, tell them this problem.
I'm hoping the .253 version helps this problem. It doesn't appear to be available for anyone yet.

Here is a complete tutorial about flashing any firmware on your Z4 tablet, even downgrade to an older one.
http://www.xperiablog.net/2015/03/1...peria-lollipop-using-xperifirm-and-flashtool/
I flashed Nordic version of 28.0.A.7.24 firmware and my touchscreen sensitivity is back to normal
If you have any questions about the flashing procedure feel free to ask.

I'm not sure whether is it because of root or Xposed, but after doing a factory reset, the touchscreen seems a bit more responsive. It is after rooting or installing xposed that the problem comes back up.

Ah, I also have intermittent touch problems. Until now I kept thinking it's because my finger is too cold or something, but I have it since upgrading to .224 also. Rooted and running Xposed v.85.1.

Yea, I kinda think it's either because of root or Xposed that's interfering with the touch sensors. But I'm kinda leaning onto to Xposed that's causing the problem.
