[Q] Help! Replaced digitizer no long allows hard press! - Xoom Q&A, Help & Troubleshooting

Greetings,
A few weeks ago I tragically dropped my Xoom on pavement. I found that the Motorola case that is designed for the Xoom is utter crap as not only did it fail to protect the Xoom from impact but flew open during the fall scratching the device. I decided to be a geek about it and repair the cracked digitizer myself.
After going through a long learning process I have it back to looking and nearly working as before the crash. However, I cannot hard press! If I press and hold on an icon (to move it) it does not recognize this input and launches the program instead. This leaves me unable to manage icons, interact with the home screen, and properly interact with the device.
Has anyone seen this problem before? I have contacted the digitizer vendor which listed the item as OEM but it seems like a firmware/software problem because otherwise the digitizer works.
Thanks!

Sounds like some sort of calibration issue, maybe there is a secret code in dialer for screen calibration.

Where did you get the screen from?

HTC Fuze (Raphael)(P4600) TouchFlo 3D Not working

hi!
This is my first post here. I have the following problem: yesterday my phone was fine...today not. Yesterday I was using the touch screen as usual with no problem, today the battery was to low and I turned off the phone. When I get back home, I connected the phone to charge it, and PUF!! the touch screen was not working at all...sometimes I can tap some menu, sometimes not, but in general terms, I can only use my phone with the keyboard. I did a soft and hard reset and nothing happened, I don´t know what else to do. I see this is kind of common problem, but no one has a common solution. Any suggestions?
Thanks!
My phone has windows mobile 6.1 Professional. CE OS 5.2.19971 (Build 19971.1.2.6)
ROM version 1.95.502.5 WWE
Radio version 1.02.25.32
Protocol version 52.39c.25.22H
u were able to use the windows 6.1 explorer? like looking for files under files explorer with no problem?
my phone is just as new as yours, i feel so frustrated! I was able just to use the keyboard, no touch screen commands were functioning. As i said, I have seen too many people complaining about this (if I would have known that, I would´nt buy this piece of crap)

At any time did you apply too much pressure on the screen?
Is your d-pad still working?
What about other hardware buttons besides the keyboard?
As I said, one day was working perfectly, and next day a kept it turned off since the battery was gone, and I was not at home to recharge it. So basically one day was fine and 12 hours later was not. The rest of the buttons are fine.
I did a hard reset, and at some point of the process the device indicates that I need to align screen, so a small cross show up in the middle of the screen (yo oughta know how is this...) well: I tap the cross and nothing happens....I tapped again...and nothing happens...3 tries later, finally the cross moves and the process goes on, To complete the process it takes me about 15 minutes!!!!!! but still nothing works out, the align screen process starts over again, and thats it!
At least, before the hard reset I was able to start my phone....now is impossible
Dont know what to do...

well then you have several options:
1) bring phone back to the entity you purchased it from considering you stated it was new it should be covered under warranty unless you purchased it from eBay w/o warranty
2) If you know it is the Touch Screen then I suggest using xda search function and searching "Think your digitizer is broken" and apply it the Fuze rather than the Tilt
3) attempt to replace the screen
4) sell it "as-is" for a loss
Problem solved!!!
Thanks guys for the suggestions. This seems to be a very common problem. But in my case the solution was simpler than I would ever though!! I read in other posts that this unresponsive touch screen problem is usually created by particles of dust, (sand! in my case), stuck in that tiny gap between the screen cover and the phone body, and the solution was to gently pass a piece of paper thin enough, (flexible plastic CD cover, in my case) well....Having tested all kinds of software """solutions""", and been prepared to pay for an expensive fix (I live in Costa Rica, this kind of phones are not common use, so fixes are expensive)...so I gave I try to this solution...and surprisingly IT WORKED...there were lots of dust, and even sand grains stuck in that gap, and like the phoenix...my phone got back to life!
Its amazing how delicate are these devices!! I think they are intended for enclosed-temp-controlled-ultraclean places only.
I hope this helps a lot of people having the same problem.
Thanks!

More info needed on "HTC fuze touch screen not working"
Hey, Ive tried following the thread about the htc fuze touch screen not working... up until the part about sand in 'some space between something...'
can someone provde more context/ pics? of where the sand might be.. because it sucks trying to use the fuze without a touch screen.
thanks for the help.
and the HTC customer support immediate went to the "well just hard reset the phone"... how quickly they are willing to erase all that data and hours of work to reconfig the phone..
any help is appreciated...
They were talking about the tiny gap between there the top layer of the screen (the material you touch) comes into contact with the body I believe. What you can try doing is running a piece of paper or something thing enough to wedge out the dirt in that area.
another somewhat common problem is the newton ring. You'll see an oily residue in the center area of your screen (it looks like rainbows). What I believe happens with this is your screen gets stuck to the actually LCD display underneath and doesn't bounce back to go back to it's resting state. What some people have said is to get some sort of adhesive material and use that to pull the screen up gently, so it goes back to resting. People have used tape and the such. Just be careful you don't pull the screen off your device.

Thinking about restoring my TP

Sooo, my Touch Pro has acquired many scratches along the way, and the buttons are a bit wonky. The home button has a sort of... Fold towards the upper left edge of it, the spacebar and backspace button requires more firm press for it to respond and I'm thinking of giving it a new lease of life.
As for the scratches, I was wondering would Brasso work? What would you guys reccomend? Same goes for the other teency problemos that's starting to get me to hate my TP day by day xD
Pick up an OEM case/keyboard (digitizer if screen scratched) off eBay, have some genuine cases off recycled devices at graded conditions.
Any other option is pointless.
Interesting, I've been attempting to search for guides on xda-developoers regarding how to change them pieces of hardware but I can't find any.
Do you know of a guide somewhere or would the process require more of an intuitive approach? They keyboard's top priority at the moment sooo, the rest can wait xD
How bout the screen itself? There's no deep scratches, just minor ones from daily wear and tear accumulated over the months, how would I get rid of em? Or AT LEAST make em almost unnoticable? =D
As for the buttons on the main screen (the ones with the call and hang up buttons), is there any way to replace them or am I stuck with em forever?
EDIT: I popped through the archives and found a couple of links, now to actually know how to replace them :s What I'm gonna be replacing would be they keyboard as a priority, but at the same time, I'd like to know how to replace the digitizer or the LCD itself. I heard the latter would be a more complicated process and due to a teenager's allowance, I doubt I can afford to lose this phone or break the parts that I plan on buying xD
Service manual can be found in wiki & via google search.
Screen replacement tips can be found in some threads & youtube may have some guides too.
It is not too hard if you read up well on dismantling & take a lot of care.
You could always strip it down before commiting to purchasing parts and then you can judge your chances of successful reassembly before commiting $
Another option could be buying a device with hardware fault if housing & screen good !

[Q] HTC One X - How to replace hardware keys

Hi,
I've got a question related to the HTC One X. More specifically, all of a sudden my soft keys (back, home, options) started not working. The thing is, I took a look over eBay, and a screen replacement doesn't seem to be that expensive.
Unfortunately, I'm not sure which I would need to buy. I saw there is a LCD screen and a screen digitizer. Which one would I need, or would I need both? I've seen that basically the bottom keys are all connected to a strip and I figure that if I change that that part of the phone, my problem should be solved.
Now, another question would be if I should do it alone, or should I take my phone to a specialist? Taking a look over some YouTube videos, I saw that it's not that complicated to replace the screen of the phone. However, I wouldn't want to start something that would end up messing my phone ever worse than before. I'm not completely retarded when it comes to electronics, but still, better to be on the safe side.
I'm just hoping that some of you guys did this before or has experience with this sort of stuff and can offer some tips.
Thanks a bunch.
You'll need to screen and the digitizer, trying to separate then without destroying either is virtually impossible. The best option if to have it done professionally, but that is also the more expensive option obviously. If you have the right tools and the capability you can do it yourself, but I wouldn't try it unless your confident.

[Q] Ghost Touch issues fix?

I bought this tablet off Amazon's Warehouse Deals. It came to me dinged and scratched up, but operable. I noticed the touch screen was a little off and would report false touches occasionally, but I didn't think it was anything to worry about. Like a kid in a candy store, I raced to get a new ROM so I could optimize this thing. In the process I unlocked the bootloader, rooted and installed PACman ROM. Ghost touches disappeared--gone for like 3 whole days. I'm ecstatic, and falling madly in love with this tablet. Then I notice the ghost touches coming back after the 5th day I have had it. Now its showing about 3 ghost touches almost constantly in one vertical line (in landscape) on the right side of the screen. Pretty much totally inoperable. I have scoured all ends of google, and most of the time it spits me out here, searching thread after thread of nothing but "RMA it". My questions are:
Is there any fix to this besides shelling out money for a new digitizer? Is that the general consensus that the digitizer is the root of the problem? I know I'm able to return the product, but does anyone know if Amazon is going to give me grief over an unlocked product that was a scratch-and-dent deal anyway? Any way I can re-lock the device? I've seen multiple threads with replies saying "lol didn't you read the blah blah? no way bro", but these were posted a couple months ago. Maybe something new has come up. I guess I just feel sorta rooked because I bought a defective piece of hardware, and now I can't get a refund just because I modified the software.

Same thing happened to my brother's tf300t. He returned it as defective, but I guess you could replace the digitizer. As far as I saw, it was a hardware problem, so it requires a hardware fix. Sorry

I got a similar situation in the last two weeks. The problem I have is that my TF300T is keeping rebooting by itself. I've googled it and people say most likely it's a hardware issue. I am trying to find a way to see if the device can be reset to factory condition so that I can return it for repair. Looks like we are on a same boat. Hopefully I can find a way to do so.
Just an update on my issue, in case anyone else stumbles across this particular problem. So far I have gone almost a week with no ghost touches. I popped off the back of the device (three guitar picks did the trick), and disconnected the digitizer ribbon cables and reseated them. Problem vanished. My best guess is that the keyboard dock puts odd pressure on the device. That mixed with rough handling is bound to cause some problems.

It could be the power button is jammed? I know mine is really touchy (all I do is tap it with my stylus and screen turns on/off. Good luck!

Thank you. I just got mine from Groupon as refurbed.. (they did a ****ty job, apparently) Ghost issue about 2 days after getting it out of the box. By then already unlocked and flashed CWM.. sigh.
I'll try your fix tonight. Any chance there is an image of the right connector/ribbon?
Hopefully the image quality isnt too bad. I took an exacto knife and gently pried up the black foam squares, set them aside and worked my magic. Hope this helps. Just be careful with the ribbon cable (duh). Hope this helps!

Thank you! I'll try this adventure later this week.
Did this today.. So far, 20 mins on it, and no issues. Typically took about 5-7 mins before. So, crossing my fingers this is gone.
THANK YOU! I can go back to enjoying my tablet
Im in the same boat with this Ghost Touches Issues, and its getting worse, sometimes im working at college and this Ghost appears and the tablet gets almost unusable, Only the Keyboard Dock saves me.
Please if you can give me more detailed instructions i think i would be brave enought to do this surgery to my tf300t, merry christmas!

i just noticed that when having a ghost touches attack, if i put pressure con the tablet, lime trying to bend it, the touches vanish.
I also have the ghost touches but it seems to only happen when the screen is dirty. As soon as I clean it off, they go away. Would a good screen protector help with that? I may go ahead and try taking off the back and messing with it.

I thought mine was fixed, but doesnt seem to be. I technically didnt remove the connectors.. I was nervous, they are WAY fragile. I simply unlocked and pressed firmly on them to attempt to reseat them..
Problem seemed to go away until I used Chrome. Chrome is what seems to trigger odd behaviors for me. I may try another browser and see if it still happens.
I've been dealing with this off and on for about 8 months; asus HAS to be aware of it as my tab has been back twice for this issue (out of warranty now) and I take advantage of their complaint form every month or so.
Here's what I've been working off of (based on personal experience/experimentation):
Re-seating the cables might help for a day or less, but isn't a permanent fix. I even went as far as strategic pieces of tape to hold the flex cables in place and tape across the connectors to encourage them to stay closed.
The first time I popped the back off the larger of the three flexes (with the silver wrap) had partially worked out of the connector on the driver board. Re-seated it and problem disappeared for about a day.
The large copper heat spreader was basically spot contacting the CPU and really wasn't touching the smaller ancillary chips (unit had been running warm for a few months, thought that might make things wonky). I pressed heat shield back down to ensure adhesion, and slightly molded the copper around each chip. Ghost touch gone for two days, unit way cooler running than before.
Here's the interesting one to me. Tonight I noticed that even just hovering my finger close to the screen I can get the 'touch dot' to show; this got me thinking about static. I held the tab in a way that at least one finger of one hand was touching the screen, like towards an edge (out of the active area) while using the other hand to touch the screen. Seemed like one hand was grounding the screen, like a charge couldn't dissipate from the surface.
Isn't this a "capacitive touch' screen? Could it be a matter of grounding?
I too purchased this tablet and dock from Groupon about 4 weeks ago or so as a manufacture refurb. My tablet does the same thing. After about an hour or so use most of the time it starts randomly acting like the screen is being touched. And it appears to only be in the upper right corner area (kinda where the lock screen pattern show up when you unlock it) in landscape mode. Sometimes it may take a little longer of use before it happens. It happens regardless if the dock is plugged in or not. I have figured that if I lock the screen and wait a few seconds and then unlock it. The ghost touches are gone for a while. I first began thinking it may have been a OS issue and hough about rooting and putting a custom rom on it. But from what I have seen on the web it doesnt seem to matter whether its rooted or not. So should I RMA it back or has any one had permenant luck with reseating the cable?
Thanks

I'd try reseating the ribbons. I kind of doubt it would solve the problem since it's a refurbished with a latent defect. Bad ribbons would strike at random but do not wait for a while before acting up. Look at the glass surface under a magnifying glass and bright light. Hairline cracks cause this after the tab heats up, but you can't always detect them. RMA would be the safe option unless you're really pressed for time.
Ghost touches are back. Noticed I had alot of them when my storage was full. Used a previous recovery (same ROM, just earlier date with less junk installed) and it cut down the frequency of them happening. This is so weird.
I had those ghost touches when 4.2 roms started (CM and AOKP and all of the rest of them. Then someone, I don't remember who had compiled rom with decreased touchscreen sensitivity and ghosting was gone. I think they started with PAC or AOKP, I really don't remember.
Then I went to 4.3 and 4.4 roms and I didn't have one single ghost touch since then. I do noticed sometimes when I hover finger over screen it is registered as touch, but ghosting by itself didn't occur on those roms.
one cent fix
I have an ugly, but effective solution working on my pad right now. It has been in place for about three or four months.
Holding in landscape mode, pulled the bottom left corner back slightly and inserted a penny between the back and the lcd. This put enough torque on the screen to kill all of the ghost touches and it still fits into the keyboard dock. There is an ugly gap where the penny is, but it is now fully functional.
Hope this helps some of you

Is there a way to get into an S8+ with a completely (black) broken screen?

I had a repair shop try to fix my broken glass and they managed to screen up the whole display. According to them the glass and screen are integrated and they tried a second screen in case their first was just defective and it didn't work. Ultimately they blamed something like the PMCI port/card???
Anyway, they replaced the phone with a new one. The old one still works as my smart watch is still paired to it and I get alerts etc from it. So internally it seems all good, but the screen itself is just toast. So I have what seems to be a good phone but with no display.
What cool things can I do with it?
Is there a way to "hack" into it without the screen? In other words side-load something using only the physical buttons? For example boot into recovery mode and then click down 3 times and then... yaddie yadda.
I'm just trying to figure out if this thing is totally a lost cause or if I can still use it for something.
P.S. if it's a lost cause, how does one destroy old phones that can't be hard reset in order to recycle it? It has a sealed battery so drilling it or smashing it like old phones isn't really an option anymore.
