The touchscreen issue (affects all EVOs?)
- Thread starter Caitlyn McKenzie

What about screen protectors? I'm trying to find some common ground here. It's almost Excel sheet worthy at this point... Excuse me, I meant google docs 
.
I just found a micro fiber cloth in my wallet, I know, and can't replicate this. I'm at work and about to go to the bathroom so I can take my clothes off and test lol.
Has anyone who didn't experience this been able to create this?

This is normal...
Setting your phone on a sock or something with a very high insulating effect will cause touchscreen glitches sometimes. This is a common type of quirk present in most capacitive touch screen phones and devices.
It is due to grounding of the phone and how it affects its ability to sense the conductivity of the flesh of your finger tips. You might also find that certain chargers (particularly high current) will render the touchscreen to not work at all or even make it sense touches that do not exist (ask the droid milestone users!) This is not really a bug in the phone, just a manifestation of the technology in it under atypical usage conditions. If you touch the phone with your hand the problem goes away.

I am having the same problem, but it happens anytime the unit is level (like on a desk) and I am not holding it, I can put the unit on ALL types of materials (i.e. paper pad, mouse pad, laminated desk, glass) and the top portion of the screen becomes unresponsive. I can't get notifications to work and the top 1/2" of the display is intermittent.
Mine phone also seems to sufffer from this. Only top half of screen. I have the Body Gloves and screen protector.
I removed the screen protector and the problem went away! (Kind of sucks removing a InvisibleShield being one and done I have to call them for a replacement)
I found out the problem. This is really crazy but the evo is more touch sensitive on the bottom of its screen then top. Its not really noticeable without a skin, but with a skin its noticeable esp invisible shield. Stay away from invisible shields. They make the screen have a rubberized feeling that causes your finger to drag across the screen which causes the screen to have issues on the upper half of the evos display. I switched to sprints and its responds a lot better. Registers my fingers a lot better due to no drag. I also recommend phantom skins. The only reason I can think of for the evo having this issue is that the key board area needs more sensitivity than the rest of the phone. Maybe htc will fix this issue with an update.

But why does the problem go away when the unit is held? I also used another after market screen protectors (PET, Clear Type) and the problem reoccurs. So for the meantime I am not going to use any of them.
Without a screen protector on I can use the tip of my pinky finger and it as accurate as can be.!

I think its kind of funny that somebody posted a realistic reason this happens and everybody keeps pushing on like the post doesnt exist...
Capacitive touch screens sense your fingers by measuring how your flesh changes an electrostatic field over the screen. Therefor it makes perfect sense that they will be susceptable to things that can have an electrical effect. ie, static electricity or the phone not being grounded to you or something else.
Also, capacitive touch screens responds better to larger touches (like your thumbs over your other fingers) and firmer touches because it causes a more defined fluctuation in the eletrostatic field.

I own an iPhone 1G, iPod Touch 2g and a iPhone 3Gs all have capacitive screens and none of them have this problems and all three of them have screen protectors on them.
Different devices may behave slightly differently in any given situation. I have a Pre and an iPod touch 3G that doesnt behave like that either. Neither of them have a massive 4.3" screen, either. Thats a lot of touch sensing real estate.
The screen protector could be affecting how static electricity is around the touch screen.
Are they all Zagg shields? I'm wondering if that solution drying up between the protector and the screen creates some kind of block if there's some kind of alternate electricity close to the screen.

Have mine laying on a pretty puffy comforter, screen seems to be working fine, and I threw on an Invisible Shield screen protector about 20 minutes ago. I will try other things to see if it rears its ugly head....

Has anyone noticed in the bottom left corner that the screen press in and all the other corners are solid and tight
I attempted to repeat this issue, but had no luck. I have a WriteRight Screen Protector on currently, until I get my InvisiShield for it in.
