First of all sorry if my English isn't quite perfect, I'm from Argentina.
So, today I received back my MXP from the service. Broken screen so...
It work perfect now (sort of) but I noticed a weird behavior. The touch screen doesn't work like it used to do before the "accident". I mean, looks pretty bad calibrated. Random swipes on the keyboard while I write, keys that doesn't work unless I really press them (?) and so.
The question is...There's a way to do a manual calibration?

This isn't a "calibration" issue, this is physical damage to the LCD panel and/or digitizer, you should replace both (and probably the battery since you have to take it apart)... Honestly, the value of this repair is questionable, you need a new screen/digitizer assembly and back cover assembly at a minimum, in the USA this would put at probably to 60-70% of the value of the device, and if you add a new battery the cost jumps to around 75% or so, making the repair clearly too costly in most cases.
And to directly answer your question, no, there is no "calibration" method like older resistive panels, capacitive panels do not use/need calibration.... this Reddit thread explains the difference a lot better than I can.

This is so true. And when I got my display replaced the screen wouldn't work even with the slightest bit of moisture on my fingers. So crappy

Just looking at replacing the screen on my blackstone as I've scratched it to buggery, so was perusing ebay and happened to stumble across this little beauty:
http://cgi.ebay.co.uk/for-HTC-Touch...trkparms=65:12|66:2|39:1|72:1683|293:1|294:50
Really HAD to share this with the community and see how other people react to the fact the screen on this looks like its made out of paper. In fact one edge is bent in the first picture.
...epic lulz.
Also on a side note, can anyone recommend a method for getting the screen replaced cheaply? I'm tempted to call HTC; I'm well within warranty, having only had the phone for 5 months but I know they're gonna charge me an arm and a leg. I see a lot of digitizers on ebay, but not sure if they include the front screen part which I actually need to get rid of the scratches. Any help would be great!
The seller has nearly 10000 positive feed-back and the screen looks fine to me.
Although how someone who needs a new screen because he does not even use a screen protector can describe someone else as an epic failure is beyond me.
heres the service manual, hope be helpful..
enjoy...

Yes I noticed the seller has a good positive feedback, but don't you think that the fact it looks like it's made of paper is slightly amusing?
And yes, I didn't use a screen protector... sue me. This is why I was asking for help from a knowledgable community; thanks for the flame and a post of non-useful information.
Cheers for the service manual limx, having a flick through now
I could totally be off because I am new to this techie stuff but the listing says "This is Touch Screen (Digitizer) only, LCD Screen is NOT Included"
Yeah, that is just the digitizer, hence why it is "paper" thin. They are supposed to be!

From my experience, it is really hard to change de digitalizer because it is fixed to the screen. And if you force too much, you will break the screen also...
Just buy the kit screen+digitalizer, easier to replace but also more expansive
Hi, I've now used the Nuxus One for a few days and I'm pretty happy with it and all it's fancy fetures.
The phone works flawlessly and the only minor issue I'm willing to report is the fact that when the phone is lying on the table the touchscreen doesn't respond as quickly as it does when holding it in hand..
I've also noticed that if you touch the shell of the phone with a finger while trying to use the touchscreen, everything goes back to normal.
Is it a flaw only present in mine or is it an issue that involves the capacitive touch screen of the Nexus?
Video Proof
This is the video I've taken with my other phone so it would me much clearer what I mean..
The quality is not great but I hope it will be explicative enough..
http://www.youtube.com/watch?v=hXPpyGwuSzM
mine work correctly, try it on another table
I've tried it on different surfaces but the result it's the same..
Problem is that it doesn't always do it, so it's difficult to judge if a surface works better than an other.
I've called HTC support and together with them I've done some tests, like letting another person use it the same way, but nothing changes.
I've also done a hard reset and nothing has changed so I think I will have to send it in hoping they will fix it..
I envy you in the US where you can just ask for a replacement...

Hi,
I don't think so, since I've now tried it in different environments and by different people...
This is very weired..and annoying..
I've had my Nexus One for over a month, but I recall having the same issue one day early on.
Similarly, I've had days where I can't operate the touchpad on my notebook computer because my fingers were dried out from handling solvents.
I have an associate that has a similar issue when the phone is in a leather holster case. She has to take the phone out on occasion to operate it, most while driving.
havent had any issues. Call them for a replacement
I think I will do so!
The problem is minor but sometimes can be a real nuisance..
Looks like screen isn't grounded properly.
Yes, I think so too. It must be something electrical. When I keep it in hand or touch it, the static electricity must not influence it, but it does so if I try using it lying on its own.
I've taken another video changing the surface on which I use it on..
Take a look: http://www.youtube.com/watch?v=iZ-nS_h5Pqs
I'm glad to see you're still investigating. Because the problem is so repeatable, and the fact that its not a common complaint, I'd conclude theres a something wrong with your phone.
One thing I'd try is to remove the battery for 8hrs (overnight) and see if that make a difference. I've worked with a lot of electronic devices that behave badly after receiving a static discharge. Sometimes leaving it sit without power helps the static dissipate.
But the fact that it works while on the laptop would indicate a poor ground from the touchscreen circuit to the chassis of the phone, as the proximity of the laptop changes the capacitance of the internal circuit enough to overcome the lack of effect that the chassis alone needs to provide.
hehe I have to investigate to be sure this is a bug relative to my device so that when I will send it in for repair they will have to find a way to solve it and not just pretend it doesn't exist...
try pressing with all skin and not with your nail. It needs heat to work.

No, it doesn't. To prove it, hold a metal spoon and slide it across your screen. Mine works.
this was a common problem on the G1 and the way the capacitive screen was designed. In order for it to be functioning completely, HTC told users that he needed to have it in his hand or at least a finger or two touching the phone. HTC said that it simulated a circuit (the hand on the phone made a complete circuit while just touching it left the circuit incomplete) I have noticed the same thing on the N1... it works great in my hand on if i am touching the sides with a finger and scrolling or using it, but if i just lay it down and try to scroll/touch with 1 finger it becomes much less responsive, the same way the G1 would.
i will see if i can find the exact thread over in the G1 forums where all this is posted.
It makes sense, but then, why others work? mmm...

The only thing I found while googling is that you need some humidity in the air for it to work effectively. I'm really not sure if that applies to this specific design though.
I've never had an issue with using the screen on a table, so this is probably isolated, I'd give htc a call and ask for repairs.
Edit: I just tried for the hell of it doing the pinky touch on the frame, and the soft buttons became much more responsive. Hmm
Greetings,
I tried to search for this problem on this forum but I couldn't find anything specific to this device.
The tablet works fine in all aspects, except the screen flickers when the aluminum back is stressed, i.e. when its being held. The tablet screen will flicker in brightness as the back is pressed.
Usually the most reliable way to reproduce the problem is to flex the tablet, as if you were trying to split a piece of plastic into two by gradually flexing it until it breaks.
Therefore, I have concluded it is a hardware problem, but I don't know exactly what.
I apologize if I'm difficult to understand, and if you need any clarification, let me know.
Thank you everyone for your time.

Hey Kevin,
Yeah, seems like a hardware issue. But I advise not to "flex" the back too much
Probably could be 2 things.
1. Loose connector for the digitizer
2. Bad digitizer
3. Something grounding out against the case.
So my guess would be to spit the case apart. You can find videos on Google Search showing the procedure at You Tube. Then a good inspection of components, paying attention to connectors and the boards (for cracking).
I saw the other day that there are plenty of parts available for the 500, like digitizers, display glass and several other items. Check E-bay.

Thanks for your advice Moscow Desire. I've taken the back off before but noticed nothing unusual. Should I just take every component that can be separated out and inspect it? Sounds like a recipe for disaster for an inexperienced person like me.

Hi Moscow Desire,
I have taken my tablet apart with the instruction from the videos but I didn't see anything that is loosen so far. Do you think I will need to unscrew everything until I take out the screen to know what's wrong? My screen keeps flickering with white lines at the edge of the screen and it's really annoying. :crying:
Thanks!
hi,
what is the advantage of buying this screen?
http://www.ebay.com/itm/New-Touch-S...e_Replacement_Parts_Tools&hash=item4d16e48a92
what are the risks?
or compensates more buy:
http://www.ebay.com/itm/Replacement...e_Replacement_Parts_Tools&hash=item5d43fc8537
The first one seems to be Synaptics, without the frame. It means you have to glue it to your old frame yourself. No need to worry about speaker size here, since it won't include one.
The seconds one seems to be Atmel with frame, but notice the big speaker. It must be compatible otherwise the speaker stops working (as far as I know U8800 ships with small speaker, but I can't be sure).
is easy to paste?

It's not hard at all. You just need to be careful not to spill it on the touch screen visible part.
Getting the old touch screen off might take some time, as the cover is not that strong. I removed it slowly and it came off pretty well.
is there any tutorial?

How about this one?
ebay.com/itm/New-Touch-Screen-Digitizer-Huawei-U8800-Ideos-X5-AT-T-/280972093595
It' a little bit cheaper and looks the same as the first one, in the first post.
I'm having some problems with my touchscreen, where sometime it detects some inputs in the right area of the screen. It's truly annoying, as you my think....
I'm thinking about buying a new one.
Which one is better by the way, Synaptics or Atmel? I would like something cheap, but that don't work/feel garbage...

Synaptics is more or less ok, but Atmel is more configurable and with my ROM you get 10 point multitouch.
The video is nice, but it seems to describe the method where you have touch screen with the FRAME, so it does not involve replacing the actual digitizer. The eBay link offers just the digitizer, so an extra step is needed to replace the digitizer in the frame with the new one.

I thought that the multitouch limit of 2 was an hardware thing! That is very good! I'm using your CM11, and I can only make 2 multitouch at a time. So, it's a Synaptics touch, right?
Aren't you going to change the driver in the next ROM, because of the problems turning the screen off/on?
Keep the good work on that.
So, the initial problems (2012) that the Atmel touch had, are gone?
About the video, there is really one steep missing. I'm a little worried about damaging the metalic frame arround the phone, to separate the "glass" from the frame. Maybe from the inside it's easier, i hope.
Thanks!
So I got a new screen, but I think it's a cheap crap thing. Touch accuracy is way off, it seems too sensitive or something. It scrolls when I just want to tap, for example, and I keep hitting the wrong letters.
Is there such a thing as touchsvreen calibration on modern devices? Or did I just get a dodgy digitiser?

Yeah nah not gonna happen, took two weeks to get here and was only $40 anyway lol.
I don't know if it's placebo but I did run a Touchscreen Calibration app on the Play Store which seems to have helped. Not even sure what it does, but lots of other positive reviews also have similar results.
Only downside now is that it's sometimes not sensitive enough, but I'll get used to that. At least now I can type properly.
If it is too sensitive, what about using some screen protector? Maybe it will lower the sensitivity?

Maybe. I do have the one that came with the phone.
I dunno, sometimes it's too sensitive and other times it's not. I think it's just a cheap digitiser. But I might try that anyway, good idea.
