[Q]Part of touchscreen not responding - Huawei Ideos X5 U8800

Hi
A few months ago (november) I noticed that a part of my touchscreen wasn't responding when I touched it. (3-4mm on the right side) I asked here for help but you advised me to send it back. That's what I did on the 17th november.
Yesterday, more then 7 weeks later I finaly got my phone back. I was really happy but when I noticed the problem wasn't solved, I coudn't believe it. The only thing they have done to my phone is the following:
-Reset everything
-put the U8800V100R001C00B135SP01 firmware version on it. (I updated it before to 136 oversea)
Now I don't know what to do. There was no letter delivered with the phone with more information.
May update to 2.3.5 solve the problem? I have a synaptics touchscreen.
Thanks in advance and sorry for my bad language.

Usually when the digitizer fails you loose a large percentage of the screen touch, like 25% or more percent, not less than 2% that you seem to be missing.
So either the service personnel wasn't thorough enough to check the digitizer and thought that the phone was ok so you got it back as is, or there isn't really a problem...
If you post a video we might be able to say which case is which, if it is the first, complain and ask for a replacement.

I have the same problem too.
I found out this problem after my baby lick on my phone, was her saliva short circuited something inside?
About less than 10mm on the right side was not responding. I realized this when trying to type the right side of the virtual keyboard and weren't able to type letter 'o', 'p' and other button in that area.
Is this means that my digitizer is broken? I think I have experienced this in the past, but maybe it went to normal again without me noticing it.

Try a costume ROM. I had a shaking screen when I longed pressed it. This happened with the stock froyo rom, oxygen, MIUI and the old cyanogenmod. I have no problem with the current DZO's ICS rom.

Hmm, not too keen to change the stock froyo rom as I use my phone for work such as using my work email etc. Don't want the extra hassle to try out some roms.
Maybe I just send it to the distributor. Thanks for responding.

Titan Keyboard failing

some keys i have to press super hard, other keys i tap and it types the key like 3 times
like when i press a
it types
aaa
and im like wha?
i am still under warranty, should i just put original stock rom back on and ask them to repair it or try and get it switched out for a vogue 0.o
I have a similar problem on my device. Is this a known problem?
Ditto here, the Function key has to be pressed hard, and some keys in the first row are acting up as well, but primarily the Q key.
I'm not sure that this has been officially acknowledged by HTC or any providers but it seems to be a widespread issue for end users.
While the "hard presses" for Function, Q and P seem to be a physical problem many users have reported that using the following CAB fixes the duplicate entries.

This is deff a problem. My phone does the exact same thing as OP.
I press a and it types it three times. This is the only key that this happens on.
I didn't realize how bad the keyboard was degrading until yesterday, when my Mogul was replaced. For me, the ./0, y/1 and function key were the worst offenders. The unit was swapped because the usb port broke. The port failed because it's a really cheap design, 2 pins broke off . The rep in the repair center insinuated that it was a really common issue, she didn't even look at the port when I explained the problem. On the plus side,I got rid of the dreaded white spot and my keyboard works well again, but for how long? The keyboard, screen and usb port problems are all common complaints on this board and others. What I surmise from this is that HTC makes a pretty crappy product! When this phone is retired in a year or so, I'm hopeful that I'll be able to replace it with a non HTC/non Windows Mobile (or whatever MS calls it next). Every time I use my phone, I wonder if it be wonderfully helpful tool this time, or a frustrating pain in the ass? Unfortunately, the later happens all too often!

These cabs dont necessarily fix the hardware keyboard issues. It fixes the old issues of the function button always being on in certain applications.
The issues that people are having is just wear and tear. The XV6800 has a cheap build.
hi guys,
same here, when i type "a" either doesnt do anything or it gives me a duplicate of 3 a's. and that started happening since i upgraded to dcd 3.2.0 an on.
also when i switch to landscape mode it sometimes writes an H or Y or P. don't know if it is OS related or hardware but it is a brand new phone and i never recall having this before going to dcds greatest 3.2.X.
edit: also i've been using quickmenu ever since 3.2.0 because of the x-button issue so i was thinking is any of you using quickmenu too?
fn key problem
So I guess many people have this "hard press fn key" issue. Annoys me a lot, especially with password sites where I cannot see the entry. Would this justify replacement from spring, i have full insurance?

I don't really think it's a hardware degradation issue. This is because there is no gradual degradation. If it were I would think just a few keys would start acting this way and then eventually a bunch of them would. With me I just all of a sudden noticed one day that all my keys were acting wonky. I think it was after a ROM flash but I can't recall any specific one that broke it (I change the ROM more often than I use my keyboard I think haha).
The CAB seems to help a little. I still have to take more care in typing than I used to but it's better than having so many repetitions of the same key.

I still say it's a hardware thing. Because if it was the software / ROM you would just be able to hard reset and your keyboard would be back to the state it was before.
My keyboard has issues with the E,O,H,Function Key, Space Bar, and the L.
It's something we will have to live with or just return our phones for a new one and wait for that one to wear out.
Just like the spots on the screen, loose stylus and so on. The 6800 was a bad build for HTC.
I Did Not Typs0r That! I Did Not Typs0r That!
ya well. it is definitely hardware. spoke to 4 co-workers with same company issued phone. one of them still has the stock rom on it, lol.. anyway
all now reporting this same issue.
i mean i was able to use my keyboard 2 months ago, and now i can't at all. its like i have a fat vogue minus 64 megs of ram. i mean i really got used to just using the on screen one.
i gotta figure out how to get stock rom back on so i can bring it to verizon and demand... satisfaction! only prob is nochem said something about it bricking your phone after putting radio 3.39 on it

Hmmm.... anyone go back to an older rom to see if this resolves it. if it does, i must throw away everything i know about electronics.
My gift to the WORLD!
keyboard fixed.
wow it was the software.
i built a rom without the htc diamond keyboard and it works fine now.
wtf? but im happy, keyboard is working normally
hummm... I have problems with the "Q" and the left softkey, I have to press them hard...
keyboard failing on Telus P4000
I got the same problem with my Telus P4000..
I think this is how I ran into this problem ...
I had radio 3.39 and dcd 3.1.2 at the time ...
I then decided to upgrade to radio 3.42.30 and another OS ROM (version I dont quite recall.)
That is when I ran into this issue with the keyboard.
So I went back to dcd 3.1.2 (kept 3.42.30 radio)
Same problem.
So i decided to revert back to stock ROM on TELUS (2.13) and radio 1.32
Still having this issue... I hope I do not have to bring in my phone to have it repaired. It will be the second time I bring it in
Flashed yesterday to DCD3.2.3 which uses the same keyboard driver as 2.1.4 (according to the changelog).
My keyboard was wonky as hell before this flash unless I installed the fix and even with the fix it would sometimes mess up. With the new ROM (and old driver) my keyboard works almost flawlessly without the fix installed.
Still everyone thinks it's hardware-related but it definitely showed up all of a sudden with a flash months ago and it disappeared just as quickly (for me anyway).
If you have keyboard issues maybe try the new ROM and see if you have a successful fix like I did.
definitely software, i should make a youtube vid to show it.
loaded up the stock rom to bring back to verizon to return saying keyboard was all quirky and i was standing there and everything was fine. im like what the hell?
what the hell brah?
ok so here is the instructions that fixed it for me:
restored stock rom
tested keyboard to see it working fine
flash it with the newer roms with radio 3.39
everything seems fine.
i can't explain it but it works.
my Problem possibly due to environment fluctuations: Heat-Cold-Humidity

Ok... after I went back to TELUS stock, i then proceeded to flash up to dcd's latest at the time: 3.2.3 with 3.42.30 radio. Keyboard issue was still there ... So.. where to go from here right ...
Well, I recalled that I began having this issue not long after flashing 3.42.30 RADIO i think it was initially. If i recall correctly, it was not immediate. I left to go camping for 4 days and my battery died .. So I left the phone off for most of those 4 days. When I got back from camping, that is where the keyboard issue began. Note: It did not get wet, but it obviously gets damp at night. My thought: phone off for extended amount of time in damp environment, somehow affected the keyboard. I don't know how, maybe some sort of rusting of sorts due to the hot/cold/humid fluctuations inside the tent (estimated environmental fluctuations>15-30 celsius with 60-90%RH). Reason I say this is the following:
I decided to pass my fingers accross the keyboard on every buttoms back and forth with a decent amount of force. Idea being that I could maybe create enough friction or force to disrupt whatever is causing the issue under my keyboard .. I did that for a bit. And my keyboard is working better. Not perfect, but I would say 90%. I barely notice it now ..
Thanks for bringing this thread up. I have beeen getting a few missed keys, and in particular, the Fn key has been flaky. Either not working or double pressing so the Fn light comes on and locks.
So, when I heard others having the same issue, a short while back I sprayed the keyboard with contact cleaner. All better now. Now the typing mistakes are all my fault, not the keyboard.
If you try this, use a plastic safe cleaner. I used Caig Pro Gold.

universal going crazy on me! keeps dialling and doing weird things!

Hi, recently my SPV M5000 has been really acting weird. it was fine using WM5 official rom, then i upgraded it to luca's wm6.1 rom, and it was still fine. then a month or two later it started behaving weird. in apps such as word, typing on the keyboard brings up the phone app, and when left alone it suddenly starts dialling numbers (the last number dialled)
i flashed it to tomal's 6.1 rom, and its still doing the same thing!! i'm at my wits end right now. could it be the bootloader or something? im using v2.06. i cant remember if i upgraded to it or if my device came with it.
thanks in advance
Try Doc format and reflash ROM
thanks for the reply, i just tried it but it dosent work
after checking it out some more, i realised most of the keys work fine, however its the h,n,j and u keys that are causing it to launch the phone app. Im not sure why it keeps trying to dial the last dialled number all by itself. i have to cancel it maybe 10 times before it stops trying.
the green "call" button on the spine of the phone also dosent work
could this be a hardware issue?
If if you tried the doc format and flashed other roms and the issue is still there it might be hardware problem...
and one thing just after flashing to new rom don't back up anything and see if the problem is still there.. if no then this bight be due to some applications in backup....
cheers
Rajiv...
sounds like hardware. you may have a sticky key. I'd take it to bits, give it a good clean and make sure the connectors are firmly pressed in - as concerns the spine keys and keyboard.
no, its not a sticky key. i guess its a loose/frayed connector
i'm reluctant to disassemble because of the form factor. guess i'll have to mothball it until i can get it repaired. i dont use it much anymore anyway, have since upgraded to a HD, but my girlfriend was using it as a mini laptop for word and skype when she didnt want to lug her laptop to college.
thanks anyway for the help
Is the screen intact? Is it clean around the edges? Did she spill coffee (cola?any drink?) on it? Is there any dirt around the screen where it meets the frame? Has it got a new screen protector installed recently?
Sounds like your hinge PCB got wet and is shorting.

[Q] HTC Legend Touchscreen Problem

hi,..
i own a HTC legend with A1 (Austria) Branding and made a 2.2 Over the air update. when i started to use it i thought that it would be faster but this has now rly changed.
Last thursday i could use my legend properly but then - 2 hours later the touchscreen didn't work any more .
i tried to unlock it but only the right side of the TS worked.
so i already tried some of the tips of some threads of XDA like hardreset , refreshing the update , and now it is a bit more useable , so i can slide the homescreen pages on different points but i cant start apps with touching..
Does anyone have a solving for this problem ?
I have no idea if the froyo update is responsible for this but I have the same problem. The top part of the screen is no longer responsive. I cannot slide the notification bar down and sometimes crazy things happen on the screen without tapping anywhere. This makes the phone practically unusable until I reboot and it usually works for some time even though the top part is not responding (notification or letter 'q' when in landscape).
Can I try something or I have to visit service? I cannot find the link where they explain how to change the refresh rate as you mention could you please provide it? also I found a couple of other threads dealing with similar problems and it looks like there is no solution am I correct ?
thanks
same thing happened to my Legend. After two months, the thing appeared, next few days all was good. Another two months and it came back. I had to send for service: they DIDN'T KNOW WHAT WAS WRONG and DIDN'T KNOW WHAT TO DO, anyway, after they sent it back to me, it's working again (until now, which is almost another two months)
My guest: there's some weird thing with the range/sensitivity of the touch screen, maybe a problem of the screen being magnetically/electronically charged without being discharged (as it should), after a while (e.g. a week) the problem disappears.
I far as I know, there's no solution. I have even found a clip on youtube (search for 'htc legend touch screen problem' or something) describing the same situation, maybe you should take a look there to for a abetter description of the case.
Anyone, please, if you know a way out of this, please, post it!
I have the same problem, the top notification bar cannot be pulled down in portrait and in all orientations I cannot use the touchscreen near the HTC logo. Mine is an unbranded and the problem just started this morning. I am running a custom rom from here and have been running the same one for a while so I don't believe the ROM is responsible.
Edit after using multitouch visible test from the market, it turns out I can't get a response that is higher than pixel 57 vertically.
I have already sent mine for service under warranty. I hope everything turns out well, because I really like my legend (form factor/design/specs). After the slow down I experienced with the froyo upgrade this problem came to spoil all these months of happiness. I will keep you posted.
EDIT:
I got my Legend back from service 3 days ago and everything looks fine at the moment. I hope that my bad froyo experience has ended.
According to the documents I received they just performed a ‘software upgrade’. This means that the problem was related to software. I guess some files could have been corrupted during the OTA froyo update. Maybe that also explains the sluggish froyo experience.
I can only suggest that before any critical updated a factory reset should be performed and hope for the best. I will update this thread if this serious problem with the touchscreen ever returns.
yeah i sent i to the warranty service too . But they said that the problem has mechanical reasons. So they suggested to repair it for 218(!!) Euros . -.-
I had exactly the same problem HTC have repaired it under waranty, so must have been a software issue, looks lik eits happening to quite a lot of poeple, pretty unacceptable consideringhow long it took them to release the Froyo update, not sur ethey bothered to test before releasing
Solution for screen problem ( HTC LEgend)
I had this problem also with my phone

the top part where i cannot access
Solution
I change digitizer and
everything works well
only buy the digitizer from ebay and replace with the one that is not working
and everything should be fine after that
good luck

Help with Unresponsive/Somtimes Crazy Touchscreen - Might need to unroot....

Hi everyone! Unfortunately, my run with my T-Mobile G2 appears to be nearing it's end.. I've had this phone since November of last year, so fortunately for me, I'm still within the 1-yr warranty. I couldn't find a legit answer on the forum so far so hopefully someone will have the information I need to know now.
Lately, my phone has been getting crazy. Sometimes it would start pressing random things by itself. Apps would start by itself, things would type by itself, etc, etc. Then, at times certain areas of my screen wouldn't work at all, most noticeably the "y," "b," and "h" on my keyboards. And this doesn't matter whether I'm using the stock Gingerbread keyboard or Swype.
To answer any questions, yes I am rooted and I have been running CM 7.0.2. I tried to flash 7.0.3 to see if that would correct my issue but it didn't. I also tried to reset the phone via Privacy within the Android UI and via Recovery, both with no avail.
My question to y'all is how can I fix this if at all? If this problem is not fixable, can someone provide me with the MOST SIMPLE guide as to how to unroot and restore my original T-Mobile stock ROM if necessary for me to send it to claim warranty.. Finally, if I resorted to claiming warranty, does anyone know if T-Mobile will be sending me a refurb G2 or a new one or a completely different one?? Thanks ... This is EXTREMELY UNFORTUNATE.
it happens to me plenty. keep the scroll pad on the side from changing angles in direct light or it goes nuts. if theres any water on the screen at all touch commands work funny. its errors in the optical touchpad and cpacitive screen technology, not the;phone itself.
edit: im stock if youre wondering
It happens even in the dark though. I think its problem with the screen.
Any word on this? the same thing is happening to my phone.
Hui,
I was also having this problem for some time and was reallythinking of replacing the phone until I finally got rid of this last week. To start with I think this is a software issue but I'm still not sure what sw is causing this. n order to fix it I had to install the rom again from scratch and did not restore anything from google. Because independent from whatever ROM I installed the issue appeared soon after I set up the phone. So if you wnt to give it try, do a clean ROM install or factory reset to your phone and then while setting up your device uncheck the option to backup and restore settings to your google account. I know that setting up everything manually does not sound great but it's better than the crazy touch screen.
Digitizer issues
Sent from my HTC Vision using XDA App
Digitizer issues, T-Mobile just replaced my original release date G2 because of it.
They will send you a refurbished model and you have to send yours back in within 7 days or they bill you $400 I believe.
Sent from my HTC Vision using XDA App
I had serious digitizer issues last month and thought for sure that my G2 was finished. Come to find out I had gotten some oil on my phone, probably from answering a text or phone call while eating at work. I took it out of its case and completely cleaned it with a cloth dampened with peroxide...not soaked just damp, and now my phone is back to normal. Give that a try and rule that out first before you replace the digitizer or phone. Make sure you clean the inside and outside of the case/skin if you have one too.
I finally figured mine out. I guess the digitizer is really really sensitive to moisture. I usually take my phone into the bathroom with me when I shower in the morning, once I stopped doing that and gave the phone some time to dry out (in a dessicant container, but rice would work just as well) my screen is back to normal. I guess the steam from the shower was enough to bring up some bugs.

Touchscreen not working

Installed IceCreamTosti HD2 ROM 0.9 worked well for a day or two then all of a sudden my screen would stop working when it went to sleep. I researched and found that there is an undervoltage script that could be causing this problem. So i deleted the script. Then it started happening again. Task29'ed, installed HyperDroid Gingerbread Xtreme to see if that would fix my problem, nope still happening. It works when it wants but the funny thing that if I get it to work, I can use it until I have to go back to the previous screen, then I would have to hit the power button to put it to sleep, unlock it for the screen to become responsive. I know it sound like a Digitizer problem but I was wondering if anyone has any other suggestions before I buy it.
Thanks!

I've already read that. Thanks
Im just seeing if it could be a Kernel problem or something of that sort.
I've had this problem on one of the ROMs i used, not sure which one since i didn't stay on it for to long.
After i flashed a different ROM it fixed it. This might seem like a lot of work but why not reinstall MAGLDR,
CWM & a new ROM. Maybe try RAFDROID HD. Yes i know its a really old ROM but its a goodie and this
would be for test purposes anyway. You can always switch back.
I read the mentioned thread before too and im sure it does sound like it happens but since it happened so
soon after you installed a new ROM it makes me think its the ROM, eventhough you tried to reinstall a
different one. Maybe you can make a backup of your SD card and repartition both your phone and SD.

After reading the other guys thread about the end key it does seem like a bad digitizer . i read other threads explaining your exact same issue . the only way to figure out if its ROM related is to flash the stock winmo 6.5 ROM . yes , i said it , winmo but thats the last resort before deeming something hardware related . if you tried the end key option , pressing really hard on the key , then i guess i would change tto winmo and try to see if it still happens then
I do have to admit it could just be coincidence and the digitizer went up but considering this happened
only a few short days after he installed a new ROM makes me feel that there is a possibility its the ROM,
or maybe even the partition he changed (if it applies) when flashing that ROM over. I still suggest to start
over from MAGLDR on, including repartitioning your phone to the proper needs of the new ROM to see
if it helps before doing something drastic like reverting back to winmo.
Thanks for the help everyone, opened the phone up. Was hard as hell! But I cleaned the dust on the contacts under the end button, still no luck. I bought a new phone. Going to get a digitizer down the road and fix this one, If anyone want to buy it just let me know.
You will get a lot more people to see your interested in selling the phone if you post it in the xda marketplace found here.
Just open a new thread there and post how much you would want for the phone. I'm sure people would be interested
especially when you can get a new digitizer off ebay for so cheap.
change an other rom,if the problem still exist,i am sorry to tell u that u should send it to fix the touch screen..
