[HTC EVO 3D] HateLoveAndroid:
Seems to be known HTC problem for years and they haven't fixed it.

install a free app called 'Draw' from the Play store. When you open it the screen turns black and then slide your finger around and it will leave a line. This will show you if all areas of the digitizer are working. Press your options button to get the menu.

On mine Evo3d the problem started with it randomly starting to start programs or even make a few calls. I now figure that is from the digitizer acting up and behaving as if there was touches in the problem area which happens to cover the stripe of screen about from 1 to 2cm up from the bottom. 0 to 1cm is ok, then 1 to 2cm is bad, then the rest of the screen is ok. What has happened over time is that section of screen no longer seems to trigger phantom touch behavior but it does not register horizontal movement. On the Draw program vertical lines draw fine, horizontal ones leave nothing. Lines drawn at an angle skip and leave vertical lines across the defective area. Unlocking the phone with the Sense ring became almost impossible and I missed numerous calls. Even now that I switched to the slider unlock it is almost all in the bad zone and I have occasional problems getting the phone unlocked.

References are phone held vertical.

The problem originally happened on the stock rom, rooted. I figured it was a software thing so wiped the phone and took the opportunity to install LeeDroid. The problem still exists.

Using the calibration tool or any of several other suggestions does nothing.

Oddly touching keys works for typing and even SlideIT keyboard works though the line it leaves jumps around like crazy. I can't play some games that require that area of the screen. On programs that allow rotating I can usually get it to work as this moves the problem to a different area.

I really don't like friends with iPhones and other brands laughing at my phone.

I started searching Google and there are a LOT of other complaints going back several years and on numerous models, but no real solution. I am disappointed that the response from HTC seems to be that failures are within what they consider acceptable because the solution seems to be return the phone as it is a hardware failure though they do not admit to it. Some people report having the problem within a week on a phone that they left completely stock to see if it really was a user software thing. Some have had the replacement phones quit within a short time as well which makes you wonder if they even replace the digitizer when they recondition them. The actual complaint probably never makes it to the tech so if it works good for 10 seconds out it goes.

I am not very happy with the 'return it' solution since I have a $25 Zagg protector on the screen I will lose and it takes time to set up a new phone, and from the sounds of things the replacement isn't a guaranteed fix. Finding out that it is a known quality control issue that is still present after numerous years has soured me on HTC. If it was a rare occurrence I could understand but not when I read so many reports.

My last flip phone was indestructible and from Samsung. After all the hassles with crappy charge connectors and keyboard contacts from dust at work on a Motorola flip it was a true pleasure. I intend my next phone will be Samsung.

when you need to type those keys in the dialer try turning your phone sideways as the dialer should rotate.
