Huawei U8950D dead spot and slow processing/lag problems - Android Q&A, Help & Troubleshooting

Hi, I was browsing one day using "Google Chrome" on my Huawei U8950D then all of the sudden my phone just hanged, the screen won't respond and the lock button doesn't work, so I had to remove the battery to reboot the device. When I turned the phone back on I noticed sudden slowness of processing of applications and a huge bar of dead spot just happened to appear on my screen, I haven't dropped it or got it wet, it just happened.
My suspicions was the software side causing hardware problems on the phone. I don't know if I can repair the screen through software but what I want to know is how can I fix the "Lag" part of the device, the "slow processing".
To be honest I'm not that much familiar to mobile devices and android software but I would really appreciate any help coming from you guys who might have experience the same problems or maybe knowledge in getting me out of the this mess.
Edit: I also experience unresponsiveness of the screen and I always need to press to lock button to sorta "refresh" the screen so it would respond again.
Need Help badly. Thanks in advance

because the touch responds perfectly the way it should when i reset my phone but after i power off the screen and wake up to the lock screen i can't unlock the phone b/c it won't respond to my touch after that
so please help out guys
thanks
hm... try hard-reseting the phone. but back up your data first using some backup software like sprite backup
Tried that as well no luck any other suggestion guys
Sent from my HTC HD2 using XDA App
I had the exact same problem, and I had to hard reset everytime, but as soon as I would press the end key it would be unresponsive. What I learned is that right after you hard reset you should only try waking pressing other keys than the end key and let it go to sleep by itself. Also did you use any EVO android builds, or Android at all, not sure if it's relevant, but that's where it all went wrong for me with the EVO build. I do find it quite odd that quite a few people are experiencing the same thing with the touchscreen and it also seems that there really isn't a solution to this. I had to send it in for a repair, and it got fixed pretty quick. Perhaps this needs to be investigated more.
i have same problem with my htc hd2
it is so annoying. i will send to repair service too..
hey i have the same problem too ! did you installed the new c0okies home tab ? because i did and after that it start it messing up.. well i did a thread yesterday about this.. the only responses i got was to send it back to repair. I just did not turn off the screen for nothing today during the whole school day it almost finisihed the whole day, it last it me about 6 hours without turning off the screen, otherwise the touchscreen becomes unresponsive.
Temporary fix/test
I just fixed it temporarily, i fixed it by taking off the battery cover and pressing down on the htc logo (below lcd) and pressure on both the front and back of the phone where the htc logo is.
if you do this and it fixes it, you most likely have a dodgy lcd/digitiser flex ribbon cable.

[Q] Freezing HD2 after lock

I know there are hundreds of threads and articles posted about HD2s freezing with the lock screen but this issue seems different to me. My problem is that whenever I lock the phone the touch screen will freeze entirely. I thought a work around may be to install a different lock screen. After installing that I can get past the lock screen but the touch screen still is not responsive. I have no idea what to do. I already did a hard reset and it still does it. I would like to add that it is completely consistent. It happens every time without fail. In order to even use the phone I have to pull the battery and I get one use out of it before it locks and I have to pull the battery again. Does anyone have any suggestions? I would really appreciate it..
Update: I flashed the original ROM to my phone and the freezing problem still exists.. I have no idea what to do at this point.
Update 2: Narrowed down the problem to being the physical "power/end/lock" button. If I slightly press it but not fully it will go to the honeycomb style menu with all the apps. If I press it fully the screen will go out like normal but then if I restore it, the entire screen is locked up. Nothing will work after that until I pull the battery.
I've directly linked the issue with the power button. I dont know why all of a sudden the power button would have a different function. The work around I found is while the phone is locked and the screen is off I can press the green button to unlock the phone and the touch screen will then function. If I use the power button it will remain frozen. Any ideas what happened?
Hello,
I got some bad news for you, this issue is actually related to the digitizer (hardware) not software. What i would recommend is called HTC for a repair and send it in, it is covered by warranty, hopefully you have warranty.
A lot of people are having this issue, no-one yet has been able to pinpoint the cause, but here is the link a thread with similar problem:

Thanks for the reply. I do not think I have a warranty on this phone considering I bought it privately. Ill talk to Tmo and HTC and see what I can do. Just a theory, I may be wrong. But I live in PA and its been getting below 20 here lately. I noticed today that my work around didnt work when I was outside working on my car. Then I went inside and used a blow dryer to heat up the phone and it started working again. The end button didn't function properly but I could unlock the phone with the green send button. Perhaps the cold weather is shorting out people's digitizers? I don't really know how they work so that's why i said its only a theory. I bought this phone in the spring and didnt have an issue until now when it started getting really cold.

Unresponsive touch screen

Hello mates.
I've got some issue with my desire x touch screen. It is becoming unresponsive.
The whole thing started like 1 month ago. I've noticed that as my phone gets hotter (playing games, using internet) my touchscreen was slowly becoming unresponsive. Firstly I was unable to scroll down my notifications (only the narrow bar at the top was not working) and then it came to a random places of screen, so I couldn't even write sms message. The thing is that it is not unresponsive at all. When I press certain unresponsive area it finally detects the touch. I tried everything, from wiping my screen with a soft tissue through removing battery and sim and sd card to wiping dalvik and cache. I've noticed, that after night the problem was almost gone. And again, after using phone for some time issue occured again. I figured that flashing a new kernel might be a good solution. And it helped and I was happy.
Unfortunatelly, yesterday problem returned. But as you probably suppose - flashing kernel ain't helping. I've also tried other methods mentioned above, but the only thing what helps a bit is leaving the phone unused for like 1 hour or so.
Do u guys have any ideas, what can I do to repair it or to fix it? Any help will be strongly appreciated

I have a similar problem after replacing touch screen. I have found the source of the issue, it could be similar to yours.
My touch screen at the bottom was glued to the LCD in a short line and the adhesive was probably touching part of the LCD cable that goes underneath. I used a hair drier to warm it up and lift off the touch screen. That way there is no bad interaction between the touch screen and the LCD. Haven't had this problem since but my touch screen is unfortunately a bit lose this way. Even now, whenever I push the navigation part of the touch screen too hard, the problem comes back. I will need something to isolate the bottom part of the touch screen from touching the LCD. I will keep you updated if I find a final solution. In the meantime, it could be worth trying it on your phone too.
I think I will just get S-OFF, revert my phone to stock and give it back for warranty repair Anyone of you guys did this? Did 7 vibrations at boot void your warranty?
I'm thinking about warranty repair, cause my bro has the same phone, but full stock, not even rooted. And he got simmilar problem to me, but with less intensivity (it just comes and goes once in a while). Also recently I got this phantom touch problem (after enabling show touch in options I saw my phone is detecting some touches in specific areas) So I think warranty will be the only option :/

Flashing/flickering/artifacting screen?

(UPDATE: Here is a link to a short video of my issue: https://youtu.be/YqKW3tU4Fhw)
So I cant seem to find ANY info relating to this issue aside from results for the LG G4, but the solutions for said phone are all over the place. Some are bad screen, some are related to sim tray, some are related to water damage and battery etc. So basically, about a month after buying this phone (KIW-L24 US version), the screen started to artifact and flash in and out randomly. There is nothing that seems to trigger it. I have set the phone down on a table while on the homescreen and watched the lightshow. It is basically a mixture of the problems seen in these videos (Feat. LG G4).
https://youtu.be/gAUkXLR7eQI And https://youtu.be/QstOH66pfiU.
Symptoms:
Screen will randomly start to flicker and fade in and out. I will also get crazy artifacting lines. (Think de-gaussing an old CRT monitor or simillar to what is seen in the second video)
If i see the problems happening, locking the phone and unlocking again will sometimes fix it temporarily. Other times the problem continues after i turn the screen back on.
Sometimes the screen will refuse to come back on. The backlight turns on, and the digitizer responds, but the screen is still black. Making sure the screen really is off, I can come back to the phone a few minutes later and it will turn on. Other times ill have to hard reset the phone (hold power button 10 sec) and it usually brings the screen back to life.
Background:
I bought the phone "used - Like New" from amazon. It came with all the original accessories and even still had the film protector on the back of the phone. I may have noticed these problems after I received the phone, but they really only started to show about a month after purchase.
At first I though it could be software related as I was running CM13 and something could have been corrupted, so i did not just a factory restore, but a full reflash. This didn't solve the issue. Restarting my phone and the reflash did help, but the problem returned. The inability to turn the screen on persists through a reset and I have to wait till the phone boots again to get the screen back. Sometimes takes more than one reboot. This pretty much confirms a hardware issue right? If i put the phone on a black screen, i can see three small fuzzy "dots" in a triangle shape in the top left quadrant. Could the screen have been damaged by whoever owned it before returning it? They are not dead pixels per se, but seems more like areas where the backlight is showing through ever so slightly more. Not visible unless you are on a black screen in a dark room. Ill upload a video showing some of the issues. Any help is appreciated!
im afraid you need a new display brodar...
Seems to be hardware issue. You can visit the nearest service center to get it fixed for few bucks if you don't have warranty.
Yeah that's what i figured, i just needed conformation. I was able to get amazon to take the return even though I was out of the return period. So at least ill be able to get a refund. Ill just pay the extra for a new one this time haha.
One question : Do u have over heat problem with ur phone ?? If u feel ur phone is more than work from the back dont replace . U'll damage the new screen also . Some ppl erported over heat cpu issue with honor ! ;.

Try moving to stock once , if it fixed stick to it for few days . 99% of possible cases for hardware issue .
So better request for a replacement from huawei . but don't mention them that u bought it used . tell them u bought it new

Question Touchscreen freezing

Hello,
I really hope someone could help me.
My phone's touchscreen is becoming unresponsive at random times but mostly if the phone is not being used and I'm moving(in my pocket). The display works fine, if I am pressing lock twice, for example, the camera app pops but I am not able to press the caption button.
This issue is resolved if I restart the phone (volume down and lock button), but after a few minutes it becomes unresponsive again.
Also I noticed that the battery drains way faster.
This is how I tried so far to solve the issue:
-delete recent downloaded apps
-start the phone in safe mode
-reset factory the phone
This issue started at the end of quite very high altitude, not sure if this could be related.
Help would be really much appreciated, currently backpacking and don't afford a new phone or spending loads of money on repairing.
Thank you
A SEU is possible. Rare but more common at high altitudes. Try reflashing to same version firmware. A hardware failure be more likely nonetheless you need the eliminate corrupted firmware as a possible cause. If under warranty, send it in.
Try downloading UsbMode.apk
It will report your touches, also mutltiple touches.
(Ok, Developer Options in Settings has a variant of this too.)
A family member had this problem too - I ended up sending it to my carrier for repair. Hopefully yours is still under warranty if it's the same issue.
