There's no solution. It's just a stupid defect. Made me switch to the G2x.
[myTouch 4G General] tinpanalley:
I may actually have an update on this. I have been using the Windows Phone 7 MIUI rom for 3 days now and haven't ONCE seen any keyboard issues. Not even the slightest bit of lag on typing anywhere, SMS, MMS, Email, search, marketplace, nothing. It would seem to me that MIUI roms have clearly figured something out. This may in fact be a software driven issue.

Sent from the XDA App
[myTouch 4G General] dclaw_fantum:
I have experienced screen response lag a few times, most recently less than an hour ago. It was worse before I lifted the pin up and would happen randomly on any app. Now, I've only noticed it happen to me when I have a large amount of SMS in a thread. Throw in some MMS & links (phone numbers, addresses, URLs) and it gets even worse. Seems like it is both a caching/system limitation and hardware grounding issue.

I know this is an old thread, but another thread got me thinking about this one and I referred that thread to here.
[myTouch 4G General] ninety6:
Has anyone tried replacing the actual touchscreen digitizer / glass to see if that resolves the issue?
[myTouch 4G General] madmanmostafa:
Hm. I was having the same issue and I just updated to the latest MIUI and am running TDJ's kernel and the problems went away. I noticed it mostly when playing a game on TigerSNES. I'd be moving about and it wouldn't respond properly or at all. A restart would temporarily fix it, but that was it. My issue sounded more software related, however.

So in summation, try just reflashing a new rom/kernel and seeing if that makes the problem go away. And try running leaner on software. I run the bare essentials.
[myTouch 4G General] fokista:
i do get this sometimes but flipping it side ways fix the letters for me
[myTouch 4G General] blue_algae:
I'm sorry for bringing up an old thread but I've been searching for a solution for this. In my experience, if I'm on stock sense rom this will happen when:

-popup notification is enabled in go sms

-and if I type fast (I actually type pretty fast)

So the fix then was not to enable popup notification. Now I finally moved on to ICS. Currently using AOKP Milestone 6 with aospX frosted cherry kernel and it still happens regardless if I type slow or disable popup notification. It still even occur when I'm using stock messaging app or even gmail!

any help is appreciated!!!!

EDIT: has anyone try putting in an HTC keyboard from stock rom?
[myTouch 4G General] bas3balman:
You can't use the stock HTC keyboard because you are on an AOKP rom, but have you tried flashing a different kernel?
[myTouch 4G General] Phateless:
I tried jonasl's HTC IME mod keyboard, with the same results.

Read the thread, people have tried everything...
[myTouch 4G General] blue_algae:
well yea, problem showed later that day. Anyway, the weird thing for me is that all works well on stock (even on rooted stock) just as long as I don't have popup notification of GO sms.

For those still having problems, I would suggest giving this a try: virtuous infinity v1.33.0-alpha3 (virtuous_infinity-v1.33.0-alpha3.zip). By this time, the problem should have surfaced but it's still working ok for me. It does take a long time for the ROM to finally load everything so be patient when it just booted up. Eventhough the launcher has appeared, response is less than snappy. Just give it a couple of minutes. Or you could use another launcher (which I did) and everything went ok again. it wouldn't hurt to give it a try. Also, this goes without saying that even though virtuous infinity alpha 3 worked for me, it doesn't mean it will work for you. there are too many variables to consider so dont blame me if it doesn't solve your problem. I'm just stating what worked for me. Got it? Cool. :)

@bas3balman

Thanks mate for answering my question. I did use another kernel but problem still exists. Anyway, thanks for tying to help me. Highly appreciate it. :)
[myTouch 4G General] malemeru:
Hey, I'm having the same problem with my Glacier 4G, the screen became unresponsive a couple months ago, starting with freezing a couple times a day (only the touch screen, the actual screen it's fine).

Now it doesn't even let me unlock it when I turn it on, first I thought it was the digitizer so I ordered one and replaced it very carefully with a new one, I've done a Factory Reset, reinstalled Android, but it didn't worked at all, the problem persist and also I've done that thing with the pin and nothing, do you think it's definitely bricked?
[myTouch 4G General] bas3balman:
Its not bricked.
[myTouch 4G General] malemeru:
Well, thanks for the good news, do you have any suggestion of what I can do? I don't know much but I'm willing to do anything, I rather try than having a useless phone.
[myTouch 4G General] bas3balman:
I'm sorry for the blunt answer lol I was in a hurry. Um I'm not sure what it could be. Someone I'm sure will know what it could be, but I know its not bricked :)
[myTouch 4G General] malemeru:
No problem, I'm not the kind of person that ask for help right away, I usually just search until I reach someone with the same problem and I fix it, but I've been searching about this problem a lot and also done a couple things too and nothing has worked. I've read all 23 pages of this thread and I'm kind of desperate. But seriously thanks for responding anyway, now that I know it's not bricked I will keep searching and waiting if someone knows something here.
[myTouch 4G General] bas3balman:
Ok well good luck :)

Edit: if you find anything let me know for future reference :)
[myTouch 4G General] blue_algae:
sounds like a hardware problem. totally different from what I experienced. Anyway, I had the same problem with my HTC Hero. Service center couldn't fix it too. I ended up buying MT4G back then when I visited the US. I hope you find a solution for yours. The problem with my MT4G screen is related to software so it's quiet easy to fix if I can find a compatible ROM (actually stock was ok but I'm fed up with GB and would like ICS).
[myTouch 4G General] Phateless:
Same here, stock is only place I did not have the problem. Very strange and obnoxious.
[myTouch 4G General] mniroy:
same here, my keyboard useless in any AOSP ROM but in SENSE ROM the keyboard runs well. Now i am using VI and haven't experience any keyboard freezing, luckily. I am curious this problem persist in every MT4G or just defect in some MT4G.
[myTouch 4G General] bas3balman:
Its definitely not in all MT4G.
[myTouch 4G General] mniroy:
hmm okay, my temporary fix is to turn off screen and then turn it on again every time keyboard got freeze, but that is very annoying. :(
[myTouch 4G General] bas3balman:
You've tried all roms?
[myTouch 4G General] mniroy:
Not all but most of them. what ROM you're using?
[myTouch 4G General] bas3balman:
Well at the moment I'm on aospx BR7, before that I was insertcoin glacier.
[myTouch 4G General] mniroy:
experience any unresponsive touchscreen so far in aspx BR7? i haven't try it. I will try it after 0.0's codename android JB.
[myTouch 4G General] bas3balman:
Nope its very quick and responsive
[myTouch 4G General] Ksunnyv1011:
I can also verify that there is zero keyboard lag/sticky keys on Synthetic's aospx roms. That and Royal Ginger are the only two roms where I don't have this issue.
[myTouch 4G General] THEindian:
I haven't had it on virtuous infinity
[myTouch 4G General] mniroy:
codename android JB also no touchscreen issue. it has aospX kernel so I think it's kernel related.
[myTouch 4G General] Jack_R1:
Sorry, my mistake. Mixed up with RoyalGlacier.

In that case, it would be interesting to test the kernel from RoyalGlacier with another compatible ROM - for example, with "regular" CM7 - and see if it eliminates the buggy behavior. If yes - the drivers are 99.9% the culprit, and should be carefully compared.
[myTouch 4G General] saranhai:
Hey what about iced glacier? That's stock.. any keyboard issues with that ROM?
[myTouch 4G General] TeeJay3800:
That's what I hope some devs can do. Most MT4G's can handle most custom ROM's drivers without any touchscreen problems at all, but a small percentage of devices only work well with the drivers included in the stock ROM and RoyalGinger. I'd really like to know what's different with the stock and RG drivers.
[myTouch 4G General] Phateless:
I don't like Sense as my daily driver, I want AOSP.
[myTouch 4G General] cbutt:
Hope it's something that can be figured out... I've been hesitant to send this phone back to tmo... I really don't want the bad screen... (I know many feel bad eMMC is a 'ticking time bomb', but I haven't had any problems despite this touchscreen issue...)
[myTouch 4G General] mackster248:
Honestly I think some bad eMMC's don't fail. Because I flashed like a couple times a week with my bad eMMC for like 4 months and nothing happened.

But yeah, I would be willing to paly warranty roulette if I were you. Since you have the bad eMMC anyways, plus touch screen issues.

Out of topic, but that new leak of the TMO Galaxy SII looks so sick!

Yea, not much I can really do about it anyway...

& off topic, but appreciated, Galaxy SII looks damn good!
[myTouch 4G General] beezie916:
Well I had to send my 1st one in because the whole right side of the screen about a finger width stopped working...on stock and RG as well...so my problem might be a little different but was a sudden change...one minute it worked and then the next it stopped...reboot and would work for a couple minutes then stop....within an hour or so that side of the screen was dead....to touch....I had a good screen and bad chip...replacement is bad/bad but so far screen been ok...have noticed a few times swype will get stuck or a button won't register...I turn the screen off and back on and usually fixed
[myTouch 4G General] Hinouchi:
Happen when I use Miui, and VU, not just typing, happen in games too. I was playing 02jam (music game) landscape mode, non responsive from time to time.
[myTouch 4G General] bere09:
Same issue here, I got it on Faux's rom as well. It can be terribly annoying. I thought it may be due to the damn screen but I can't for the life of me get it to replicate itself on stock rom. I'm glad I looked here because I was just about to send it into HTC and pay the $39 for nothing.

I have the bad screen and the good emmc chip by the way.
[myTouch 4G General] mackster248:
Yeah it's retarded that this issue is out there. I cant find a fix either except for stock or RG...
[myTouch 4G General] beezie916:
OH luckily I Have insurance so warranty replacement is 5 dollars....seems there are times the screen will stick as well and not respond to anything....back arrow or anything. Reboot will fix it but yeah...I have noticed on the replacement that i can see lines going from top to bottom using polarized sunglasses which my 1st phone didnt seem to have not sure what it is...but yeah the non responsive screen can be a real PITA.
[myTouch 4G General] mackster248:
So far I haven't noticed it all that much on my replacement phone. But I still hate the fact that my phone still has that problem...
[myTouch 4G General] Phateless:
In the sensation forum someone mentioned this having to do with the sim card???

Anyone have any experience with this?
[myTouch 4G General] lilbril11:
root

im new to xda and im trying to figure out how to root my mytouch 4g. can any body give me step by step directions?
[myTouch 4G General] mackster248:
Yeah go to the Development section and then go to the ROM Bible Thread. There's two methods, root.sh or the gfree method.
[myTouch 4G General] mackster248:
Really? So people in the Sensation forums are having the problem as well? I doubt it's the sim, mine is brand new since I got the MT4G. And I never had this problem until about May. So it was fine for the first 6 months or so that I've had this phone.
[myTouch 4G General] Phateless:
Yeah same here, only recently. They're having more complete issues, can't even unlock the phone sometimes.
[myTouch 4G General] curtisk:
actually on both the froyo and gingerbread stock roms i've had this problem every once in a while. So i think its got less to do with the rom/kernel you use and more to do with the screen itself.
[myTouch 4G General] mackster248:
Damn really? HTC's QC has really taken a stinker... Even their G1's were made well. Sad....
[myTouch 4G General] Phateless:
No kidding, this is only my 7th mt4g ...
[myTouch 4G General] cybertlc:
No problems yet here, knock on wood.
[myTouch 4G General] mackster248:
Lol I'm on my 6th. Ridiculous.

You still having the screen lag?
[myTouch 4G General] Phateless:
Yup, haven't tried RG yet. I'm hoping cm7 will eventually get an update that fixes it.
[myTouch 4G General] mark manning:
Imho, I think you guys are crazy lol. Have had 5 mytouches now and never once had a lag issue. Oh ya wait sometimes when you use a smartass governor I do, but that should already be common knowledge.
[myTouch 4G General] Phateless:
Nope, stock cm7, stock kernel, stock governor, no overclock.
[myTouch 4G General] mark manning:
wasn't talking about anyone but myself
[myTouch 4G General] cbutt:
I've got it on every ROM (including stock) ... on RoyalGinger3.0 & it started again...
[myTouch 4G General] Phateless:
Oh, got'cha.

Even stock? Wow, that sucks... It went away for me on stock, but granted I was only there for a few days before I went back to cm7.
[myTouch 4G General] mackster248:
I never implied this happens to everyone. I think its a small portion of phones that this happens to. I've seen this on more than a dozen people so far, so it can't be a coincidence or us being crazy.
[myTouch 4G General] cbutt:
Yea, I figure if it happens on every ROM, might as well just keep flashing, not much I can do about it... I think it's the touch or panel, because sometimes when I dial numbers, the right side freezes up... (when touching a 3 or a 6)... So it's not just the keyboard ...
[myTouch 4G General] jberg22:
Glad you started this thread.

I had the same problem when I first flashed VU. The problem carried over to MIUI and I had to deal with it every day for about two months. Here's where it gets weird..

When I first flashed MIUI 1.8.5 my keys still locked up. I started out using the demonspeed kernel, flashed tiamat - still had the problem - flashed back to demonspeed and since then my keys haven't locked up once. I'm now running the latest MIUI and demonspeed kernel and haven't had any problems for close to two weeks.

I have no idea what to make of this problem anymore, like whether its software/hardware or what the cause is.
[myTouch 4G General] cbutt:
Good to know. I hadn't had any problems on rg3.0 until a couple of days ago... flashed it the 3rd I think... so I got about 2 weeks before I had a problem. May just flash others & see how long/if it pops up again...
[myTouch 4G General] mackster248:
Wow really? I'm currently on the latest MIUI with DS kernel as well and the problem happens maybe like once a day, which is much better than my old phone where it would happen almost every time. I REALLY wish I knew how to fix this problem.
[myTouch 4G General] Phateless:
I'm starting to get lockscreen lag as well. I LOVE this phone but I'm getting tired of this.
[myTouch 4G General] mackster248:
Me too, love hate relationship with this phone. So tempted to just trade it for a SGS4G at CL.
[myTouch 4G General] Phateless:
I'm thinking g2x since they have cm7 already.
[myTouch 4G General] cbutt:
I like this phone, just hate the unnecessary garbage (touchscreen issues, screen display issues, eMMC...) . Probably holding out for galaxy s2... or hopefully my replacement mt4g won't be a problem...
[myTouch 4G General] jberg22:
Same here. And the problems so inconsistent, at least in my case, that it makes it nearly impossible to figure out what the cause is.
[myTouch 4G General] mackster248:
Yeah but I think it has to be software related+certain hardware since it's only affecting a few.

I've been on MIUI past month now and haven't noticed to too much anymore. Still happens, but rarely though.

HTC Glacier running MIUI
[myTouch 4G General] Phateless:
New device (warranty exchange), fresh fastboot wipe and reinstall of cm7 and I STILL have the problem. Wtf?
[myTouch 4G General] mark manning:
Ha ha told ya it wasn't the phone

Sent from my Google Nexus 12! yup I'm from the future
[myTouch 4G General] jberg22:
Same here, its happened to me only once in the past couple weeks whereas it used to happen almost every time I used the keyboard.
[myTouch 4G General] Phateless:
So does this mean I'm doomed to run stock with that phone for the rest of my life?
[myTouch 4G General] Mathato:
With VU 2.33 I barely seen the problem.. maybe 3-4 times a day.. since flashing over to eViLs DS I see it atleast 1 time every other time I type .

Also with VU and other roms if the button didn't work I just waited patiently... And that specific button would work again... It seems to take 5 times longer or they never work until i change to landscape/portrait on this DS rom.
[myTouch 4G General] akbisw:
GUYS TRY MIUI ROM. I am a Fruit NINJA!! So I know what Im talking about. Perfect slices everytime. Brought my highscores up by 300!! Other roms gave me troubles. But MIUI is Perfect!!!
[myTouch 4G General] Mathato:
-1
[myTouch 4G General] mackster248:
Part of it has to be. Otherwise people running the same exact ROM that we do should have the problem as well. But in reality only a small portion have this problem.

I have a new device, fast boot wiped, and even formatted my SD card to no avail. Still get the problem here and there. I've just learned to live with it.
[myTouch 4G General] DarkenFable:
Only ROM I have this problem with is CM7. I've had it since RC1 of CM7, and its been persistent with every release sense them. I've flashed VU, VD, Miui, and a few others and I didn't have a problem with any of the keyboards on there. On CM7 the problem stopped as soon as I installed Swype.
[myTouch 4G General] Phateless:
Tried HTC touch input keyboard and still had the issue.
[myTouch 4G General] mackster248:
Yeah, I've just faced the fact that this is just part of the phone. I'm done playing warranty roulette. Just ain't worth it anymore. I'll just stick it out for another 12 months before this contract is up to get a new phone. It doesn't necessarily detract from this phone's awesomeness, just a nuisance at times. So it is what it is.
[myTouch 4G General] AntonJart:
It is completely random issue. Sometimes keyboard will work fine, but then suddenly letter "a" will stop working. I've noticed that this happens mostly to "delete" and letter "p" in my case. Ill report other letters and roms. Will try Doubleshot now.

ATM using RoyalGinger 3.0
[myTouch 4G General] jberg22:
Not sure how relevant this is, but thought it was interesting.

http://xdaforums.com/showthread.php?t=1239238
[myTouch 4G General] mackster248:
Thanks for that, that's very interesting. It seems the MT4G has something similar to that as well. I'll give it a look. Anyone with a MT4G give this a shot?
[myTouch 4G General] jberg22:
Would the grounding pin for the mytouch be the thing that's sticking up between the sim card and sd card? It looks like there's a silver square on the back cover that lines up with this so I'm assuming thats what it would be.
[myTouch 4G General] AntonJart:
I pulled the pin a bit with small pliers, and it appears to fix the problem. No issues so far.
[myTouch 4G General] jberg22:
Nice man keep us updated.
[myTouch 4G General] Phateless:
Hmmm, that would explain why I have the problem on different phones. Same battery cover...
[myTouch 4G General] mackster248:
Yeah man that's what I'm thinking about as well. I have the same battery cover since my first one where I had no problems with the touch screen at all (just had the bad panel).

If this is truly the problem then wow... Can't help but chuckle a little bit on the inside.

Any why the hell HTC would even implement that is beyond me.
[myTouch 4G General] AntonJart:
I take my words back. Letter "t" just got unresponsive... Maybe I gotta pull the pin more, or add the foil..
[myTouch 4G General] Mathato:
I pulled the the pin up yesterday. Havent seen a problem since. I know I probably just jinxed myself but. Oh well.

Edit: Jinx myself I did. The T just stopped working.

I waited for it to happen again and then pressed against the back cover and boom. The key instantly started working. Seems that pin is the problem

For me atleast
[myTouch 4G General] AntonJart:
Interesting thing is that "t" stopped working for me first too. Maybe it is not a coinsidence. Ill try to add foil and see how it goes.
[myTouch 4G General] jberg22:
Where's on the back of the phone is the pin? I looked at the pics on the sensation thread and its a little different, so I just wanna make sure everyone here's on the page.
[myTouch 4G General] AntonJart:
The one in the middle, underneath the empty square on the back cover.
[myTouch 4G General] jberg22:
Alright just making sure. I'll probably try the foil this weekend whenever I get some free time.
[myTouch 4G General] mackster248:
I'll update the OP with this most recent findings. Maybe more people can give it a shot.
[myTouch 4G General] Mathato:
The pin between the sdcard and some card. Kinda blends in. Give me 5-10 ill get a picture up for future ref.
[myTouch 4G General] Mathato:
XDA wouldn't let me attach the picture so I uploaded it here

http://i5.photobucket.com/albums/y175/droopysnoo/0913112123-picsay.jpg

Feel free to save it and update OP if you can attach pics.
[myTouch 4G General] AntonJart:
I pulled the pin higher, and added a big piece of foil. Ill update if issue persists.
[myTouch 4G General] mackster248:
Okay, thanks! I'll use and credit it to you.

---------- Post added at 10:38 PM ---------- Previous post was at 10:37 PM ----------

Can you post a picture with how you put the foil? Did you have to tape in in place?
[myTouch 4G General] AntonJart:
Ill do it tomorrow. It sits well under pressure, so I did not add a tape. The foil is few layers thick and of the same size as a contact rectangle
[myTouch 4G General] Mathato:
Cool! Thanks.

The pin is pretty durable.. I got to pull it up quite a bit to were you can see it propped up.. haven't had a problem since...

Ill report in a day or 2.
[myTouch 4G General] AntonJart:
Had one letter, "a" stuck one time in 2 days, while the pin is pulled and foil added. Ill report if anything like this happens
[myTouch 4G General] Mathato:
I pulled the pin up. No foil And have had the "t" stick maybe once or twice for the past few days.

Way better then it was!
[myTouch 4G General] AntonJart:
It appears to help with the problem, but not completely fix it.
[myTouch 4G General] el_smurfo:
Bending the pin a bit seemed to help, but I also wonder if cleaning out the dust, including on the contact area didn't help more. I also notice that I often type without touching the back cover as it helps my reception, so now I'll remember to move my fingers when it lags a bit.
[myTouch 4G General] jberg22:
I wonder if scratches on the back cover could be a part of the problem. I know some of the paint on the covers scraped off on my mine so maybe this could have something to do with the grounding pin not working? Just a thought.
[myTouch 4G General] AntonJart:
my battery door is bit lose due to the fall
[myTouch 4G General] mackster248:
Yeah I've exchanged this phone like half a dozen times so the battery door fits, but not perfectly like it did on my first one where I never had this problem.

So maybe there's a correlation.

Also, I updated the OP with the new findings and credited the proper people.
[myTouch 4G General] keithdiggs01:
Lack of paint shouldn't be an issue. I sanded it and polished mine...
[myTouch 4G General] AntonJart:
Four days now. No issues, except letter "a" got stuck two days ago. Ill post pix soon
[myTouch 4G General] Phateless:
Yeah suddenly mine hasn't been acting up lately either. Wish I knew what I did.
