Hi,
The touchscreen digitizer on my Lenovo A820 was broken so I bought a new one and installed it. Removal was a bit difficult since my touchscreen had many cracks. Anyways, I managed to replace it with the new one without any issues. But it's not responding at all! All the physical buttons work but the touchscreen just doesn't respond. What do I do now? Is this a kernel issue? I use a modified ROM. Please help me guys. I never thought things would go this way.
Somebody please help me. Is it the digitizer or the kernel?
it is the digitizer
it is the digitizer. no doubt about that. get a new one from another supplier

Hi!
I saw few people talking about digitizer replacement on old devices. This discussion about newer devices like Touch Pro2. I have a device which has working LCD but problem seems to be with its touch senstivity. Its not supporting touch on the screen, which as per the original user is a problem of digitizer. He fell the device & got this problem.
May I know if it is a problem of digitizer since everything works completely, all hardware buttons & everything but touch support.
Can you plz help me in this problem, I got the digitizer but dont know how to put it & make the device working.
Any technical help would be highly appreciated.

bump, lolz, seems you guyz are also answer less like me.
Anyone tried disassembling such high end device? or has anyone tried replacing digitizer on his or her end?
I wish to help others in case I get a small bit of information about their personal experience.
Hi,
Could you please help me on how can we fix broken touchscreens? I'm using Tinji (Tianji i9300 s3 clone) mt6577 phone. My Einstien brain managed to cut the flex cable to touchscreen and its now not responding at all. I'm using Tinji i9300 mt6577 chinese phone.
Initially, the screen did not respond on the right and left wing where I was struggling to even unlock it.. Thought of opening the cell and reassembling it myself looking at various forums feedbacks mentioned here. I opened the cell apart but before I could realize that the flex connection touchscreen, I already had broken it and now the touchscreen does not respond at all. Dead as stone!!
Is there a way to fix it. Request your help plz. Thanks.
buy a new one. those digitizers are not that expensive and getting a new one is easier than soldering a flex cable. trust me, i tried it myself on a cannoo.

Thanks Chrizz,
Phew!! atleast I have someone hearing me on these forums.. Thanks a ton for your reply..
Request you to please guide me from where do we get these digitizers? are they screen specific as in 4.7 inch or CPU specific as in mt6577 specific? Or will normal digitizer work? Thanks.
Help

Hello
I have cracked my Digitizer of my Lenovo, and I bought a replacement
I order 2 pieces cause the first was faulty, but and the new one have the same problem
In edges it can't be pressed well, sometimges a simple press, is like doing "drag'n'drop" and similar problems (non pressing the key I pressed, but the next one and more)
Because of this is the second Digitizer, maybe it is not problem with digitizer but with something else.. But.. What?

Hi folks (my first post!) and I need some help. I have 2 of the above tablets and both are working fine. However I dropped one and the touch screen has a hairline crack although it is fully working.
I have purchased a new touch screen but I am not sure how to open the Tablet so I can replace it. Can anyone help me as to how I open it without causing any damage. I have successfully replaced the speakers on my Nexus 7 but that was easy as good old youtube covers this.
Any help would be much appreciated ,
Thanks in advance

Is it fair to assume that nobody knows the answer or does nobody read these??http://cdn3.xda-developers.com/images/smilies/frown.gif
Hey guys, I want to buy a "defective" OPO for 100$. The sellers told me that a part of the touchscreen (about 13%) is not working. He says it works every once in a while but it is really rare. I was wondering if I would be able to fix this trough a Kernel or a ROM update (he runs CM12S) or if I need to change the screen completely. The guy says he had the phone for 2 months and he hasn't try to fix it because he has an iPhone (LOL)
Thanks for your answers!

Don't think how low u have to pay for opo but must think is it usable
Nearly 20% users complaining about touch issues like
1)ghost touch
2)unresponsive screen etc
http://forum.xda-developers.com/oneplus-one/help/ghost-touches-invisible-finger-t2832822
OPO tried to solve this by firmware updates but they still not fully able to manage it
New firmware with improved kernel solved lot more touch issues but draining battery a lot for most people's
So its u r decision buy or not to buy but three possibilities are
1) buy if u don't care about u r money if problem not got solved
2)buy if screen problem is not due to any hardware issues because if yes u have to replace whole screen which cost 200$
3)if its software problem then u should know most of android rooting/ flashing /custom roms/custom kernels to recover problems
If its software problem then these are some solution

I bought an oneplus one with a broken screen on ebay.
Bought an replacement display with frame and some cheap tools for 50€ on aliexpress.
Replaced the broken screen + frame withing one hour. It was my first attempt to open up a smartphone ever.
Only problematic part was the earpiece, which I almost destroyed.
And also the lower antenna (which is fixed with double sided adhesive tape) bent a little bit.
But besides that it was very easy to dismantle the Oneplus One and to replace the screen/frame combo.
Compared to my other One the new screen looks absolutely identical. Only the earpiece grille is slightly different.
So. My conclusion. If your are able to unscrew a smartphone and are not completely lacking fine motoric skills, you can have a cheap Oneplus One. Watch the tutorials vids on youtube and the photos on ifixit.
cheers!
Edit:
Ah and yes. With my One the screen was shattered and not working.
So I have to agree to my previous speaker. It could also be some other part of the hardware not working. It's always a risk. But I assume, that by replacing the whole screen/frame, probably the digitizer problems should be solved.

I also wanted to mention that I also experienced ghost touch issues with my first Oneplus One.
Thats why I orderd a replacement screen in the first place. Then, in the meantime, until the display arrived, Oneplus released a firmware update and my ghost touch issues vanished.
But. I never had parts completely not responding on my screen. It was "only" a ghost touch issue.
i have it
Hey guys, i finally bought thé phone and the u, thé j and the n keys works 1 out of 10 times. Si it is not completely broke. How tout dix that?
Download YAMTT from play store. Test if you can paint everywhere on the screen.
yamtt
no I can't there is a small bar on the right that is not working
Probably a broken digitizer. I.'ve never read of anybody fixing this with a Software update. On the other hand, I'm not an expert...
