Last month, buy a ViewPad 10s. Great device. Thanks to this forum I can install the market and install many things. Until one day, after seeing a movie (Mobo player) I started missing the touch screen. I could not even unlock it!. I turned it off and set aside. The next day started as if nothing had happened. But with the passing of a few days, began to fail often, and not resolved by switching off. Until today that is totally screwed. Not react as it should, and I can not access at all to any of the functions. Here's a short video of what I'm telling you.
(search in youtube "viewpad 10s touch screen problem", the one from chgalvez user)
I've tried calibrate.ini, and almost all .apk calibration apps that are in the forum. I've try as last chance to upgrade with an official rom from viewsonic(1.09), but dont' work neither.
Anyway I think I can't prove anything more as the touchscreen almost no response at all.
Anyone have an idea if there a method to calibrate from the outside, with a USB cable or something?
thanks in advance and sorry for my english...

It never worked here (first day I have it) and now I even can't pass lockscreen (with viewcomb and original software I even couldn't select a language to pass the homescreen).
Why can't this be done in recovery?
My screen problems seem to come from my gtab being very sensitive to cold. When it is warm it works great, but when it is cold it is nearly non-responsive.
Had a similar issue. I plugged in a USB mouse and unlocked it and got to my calibration and ran it... It worked like a charm after that.

I have a T-Mobile Pocket Phone Edition,
It's had a rough life but as kept going for over 3 years now.
For the last year I would have to realign the screen 2 or 3
times a week but over the last few months it keeps getting worse.
Sometimes the screen won't respond to anything anywhere,
then after I tap it a few times boom works fine.
Sometimes I'll tap on the “Ok” and the “Start menu” will activate.
Sometimes drawing a line up the center of the screen will end up
shooting all over the screen.
And sometime it will work perfectly!
I thought the problems were to erratic to be hardware so
I hard set after awhile it started again,
So I hard set and installed a different ROM after a coupe hours
the problem was back.
Also sometimes the align program will get stuck in a
loop that doesn't end.
I've searched but can't find an answer? Anyone have an idea?
I've already taken it a part once but couldn't see how to get
any further after I toke the back panel off? Please help!
WOW nobody? So no one was heard of this problem before?
Can anyone direct me to directions on taking apart the Wallaby?
Thanks <><
It's a problem with touch screen. You should check (and fix) it.
Maybe it is necessary to press well screen to the motherboard. (Sorry my english).
Ok, Can you tell me where that connection is?
Thanks
Toke everything apart, found the connection, cleaned everything (w/ screen wipe)
put it all back together. Still have the touch problem and now the backlight won't work!
I've found if I press the unit in my hand the touch panel works right,
I don't think it's a lose connection to the main board so I think it must be
one on the main board.
If anybody thinks they want it for parts let me know! :?
Hello
2 days ago I got a T-mobile MDA from a friend. Only the MDA and a cradle. It had not been used for at least half a year. At first I could not make it work as it did not react to the stylus on the touch screen. But after some resets it slowly came on, and was fairly working (slow sometimes)
As I wanted English SW, I downloaded one and installed. After some time the problem came again, and I decided to switch back. Then it stopped working again.
Sometimes I can get to the calibrating touch screen, but then it stop reacting.
I read about similar problems on this website, but I cannot install the file tpenable.exe until I get into operating system, and can use the touch pad.
I tried with a couple of ROM-versions, but it seems to have no influence. Still, to me it feels like a SW-problem.
Anyone have some suggestions?

Follow up
Here is a follow up on my problem:
I discovered that if I press hard at the lower quater of the touch screen, sometimes it works again. This points more to a HW problem.
I took the MDA apart a couple of times, but could not see anything wrong. Does anybody know how the touch screen technically works?
I noticed in another post about someone with a similar problem. Do anybody know what exactly he was soldering?

I just bought a archos 101 g9 when it was on sale on woot last week and so far it is working pretty good, however I have an annoying problem with it.
If it has been sleeping for over a few minutes (regular sleep, not the deep sleep) and I wake it back up the touch screen goes crazy. The bottom left corner keeps detecting a touch event. It will cycle from multiple on/off touches a second to one on/off every few seconds. If I rotate the tablet to portrait, it will start scrolling the screen none stop to the left. So far the only fix is to do a reboot.
It does not happen every time, just occasionally when I wake it up from sleep.
Today i got a case for it, and whenever it is in the case, the touch screen goes crazy. Same touch events in that same area.
I am guessing something is wrong with the digitizer. Anyone else seen this problem before?
Have the same problem, and as I've read on xda and archosfans forums, this isn't an uncommon issue. We'll just have to wait for a firmware update, as rebooting seems to fix it, so it doesn't seem to be a hardware problem.

I have exactly the same problems.
@ARCHOS: PLEASE FIX THIS PROBLEM. THIS IS A SERIOUS BUG !
Sensitive Touch
I have similar problems with the touchscreen. If I'm holding it with one hand by a corner, it detects touch. The rest of the time it is a little jittery and releases or double taps in games. It's still not a deal breaker, though.
I hope we don't have to swap digitizers to fix it.
Hi !
Me too
...works fine after Touch Screen Calibrate , but the next reboot do the same !

I'll give that a try and see if that works. I just got a case and as soon as it is in the case it is even worse.
EDIT: I installed a calibration app on xda and it really made it worse!
What app are you using to calibrate it?
I have a similar issue sometimes.
For me the fix is simply to clean the screen.
The strange thing is, it happens even when the screen doesn't appear to be especially dirty but I put the tablet to sleep, give the screen a serious clean with a microfibre cloth and the touchscreen issues vanish.
Could be a different issue to what you guys are having but the symptoms are the same and it's an easy 'fix' to try.
Hope it helps.

Thanks, I had not noticed that area in the settings before. Recalibrating it in the cover has helped a lot.
I pretty much had this since day 1......
The current state is ; it doesn't work at all then all of a sudden It will pop back into life and then pretty much go "mental" as already described, I also found it reacts poorly to minor temperature variations, i.e going from outside to inside and general day to day travelling. Recalibrating used to "help" but now has no effect.
From watching the debug logs part of me thinks it's a bit of both, hardware and software ( just a hunch ) I noticed the driver fail to get a "ping" response from the hardware a couple of times.
I've pratically given up on it myself and plugged a keyboard and mouse in via a hub on the full size usb...... The hub has now stopped working for some reason , I'm now on a OTG Keyboard with a Virtual Mouse Driver using the numeric keypad and some adb input trickery ,
I've got another touch screen/digitizer to plug in, just not got round to putting it in yet and a little part of me is starting to enjoy finding more elaborate ways of interacting with the device... :laugh:
Does anyone know who the OEM of the digitizer Unit is? My previous investigation led me to china but information seems to be thin on the ground with this one

Same problem and even managed a RMA from ARCHOS. Thing is your OC edition fixed it for me.
Hello,
I have been using a trusty U8120 for a while now with Fresh Zodiac Fruit Rom. I was browsing on it last night and then next day the screen was just inoperable. Sometimes it would "take" some input, but it would understand something different (e.g. on a keypad, touch it in the middle "5" and it understands top right "3", but then again, "3" doesn't register either).
Here's the funny thing: it doesn't take any input whatsoever, but, if the screen is about to idle shut down and I touch it, it goes back on full light, meaning it understands the touch.. what the..?
I tried reinstalling the firmware but nothing happened.
I have confidence in opening the phone up as I have done it many times before, but I just don't know what I should tamper with in hopes of fixing it.
Any suggestion welcome. Thanks in advance guys.

Did you ever get a solution for this. My phone just started this as well

I bought a Mate 20 Pro on preorder and noticed within a few days a seemingly non-responsive part of the screen that was an intermittent issue.
Basically every now and again (often enough it’s annoying but not every time) after I unlock the display I am unable to select any app icons in the lower half of the touchscreen. The top half is fine - the home buttons are fine but everywhere from the middle down is non responsive.
I assumed a hardware fault so amazon replaced it for me - and the new device is exactly the same!
Am I just super unlucky and have managed to get two faulty devices a month apart from Amazon or is something else causing the issue?
Thanks.
Think you've just been unlucky,nothing like that on mine
Fine here too. I assume you tested this as soon as you got the phone before installing any app / custom launcher?
Have you tried running smart diagnostic tests manual mode in hicare, there's a touchscreen display test.

I only noticed it in use after I used a custom launcher however I tried multiple launchers and saw the same behaviour.
I just did the HiCare test and it says normal. I did hard reset it the other day and it hasn’t happened since so I will see if anything else happens. I can’t say I am thrilled by the thought of another swap from amazon if it does happen. That’s super bad luck.
Hi how did it go after the hard reset?
I got the same issue myself but instead of being the lower half, my entire screen does not respond to touch. I've done a hard reset my self and i do run the stock launcher. Even though my screen still doesn't respond to touch now and then after unlocking the screen or receiving a phone call.
Touchscreen issue
Yup I get it annoyingly so as well! Often takes a "double tap". Pain in the ace!
