Help Over 5 phones checked from various locations have grounding issue!!!

[Mabster]

If you cant pull down the notification bar while your phone is laying down, try plugging it in and charging it. When my phone is laying on a surface, I cant pull the notification bar down and the screen is finicky. While its charging, everything works perfectly, weird.

If you just touch the phone it works too. You don't have to plug it in.

It's not really that strange if you look around a bit:

It's a grounding issue. When its plugged in its grounded so it works fine.

Yep, this.

How exactly do you suppose I ground my phone through my BG case?

Hold it.

I've been able to pull down notification bar and use it as normal no matter what surface it is on, charging or not. Is this a universal problem? I cannot duplicate it.

and, therefore, this is not a problem, right?

i mean, if you barely notice a multi-touch problem while your phone is laying on your bed, which is like, what; .05% of the time...

edit; i just dl'd a multi-touch visualizer. i did see a problem on my table, couch, and kid's bookbag. the touches "stuttered" but were there. if i picked it up, not a problem. bottom line: if i need to multi touch, get it off my kid's back pack.

where's that louis c.k. video about how we're not satisfied with anything?

I agree with you on both counts.

I'm seeing touches stuttered on the top half of the screen if the phone is on something that is not grounded (it was a couch for me) The touches do register (I tested with a multi touch visualizer and just dragging down the notification bar) but the capacitive screen is not very responsive at all.

I, also, don't think this is a big deal. If I didn't test specifically, I prob. would have never given it a second thought.

I would guess that it could be fixed with a firmware update. I know that the Incredible has the same issues and the Motorola Droid has issues in a capacitive screen test and that has not detracted from the quality of the device. Here's the link:

Capacitive screens test ? iPhone, HTC Droid Eris, Motorola Milestone and Google Nexus One

This grounding issue, I can live with. The issue with the bottom of the glass screen coming loose is a much bigger problem (in my opinion)

Please no flaming - it's a problem for some, and not for some others. But I think at this point there is enough evidence there is an issue affecting some percentage of units.

Just as another data point - here is a video I made. I basically put a wire in between the negative terminal on the phone and the battery, and then demonstrated the issue with the wire floating, and then with my finger touching the end of the wire (i.e. providing a solid ground). I showed this using the keyboard in landscape mode where the problem seems mainly limited to the left side.

I also tried simply attaching the wire to the negative terminal of a multi-meter I had, and it produced the same effect as seen in the video: essentially, when grounded, the touch screen works flawlessly for me, otherwise it has issues on the upper (potrait) / left (landscape) side.

I was going to submit this all to HTC and if I didn't hear anything back, then to the state's attorney general and better business bureau. Not trying to cause issues, but a response that they are looking in to it would suffice.

I think that's a good approach. Someone tried explaining on another forum that this is "normal" for capacitive screens. I understand that there's an explanation for this behavior, but that doesn't mean that it's "normal". I don't see the iPhones with capacitive screens having this issue.

My EVO is doing this in landscape and prortrait modes. Very frustrating when you get a text while watching a video with the kickstand. Good thing my screen is seperating from the bottom of the EVO. I will be getting a replacement asap.

Mine works flawlessly exept for this issue, just contacted Sprint about it and they said they will gladly replace it when they get them in stock again.

So mine is going back for this, what is the point of touch screen if its docked in your car and you need to do something navigation wise and it dont work?

I look at it like this, atleast I got one, just use it as a test mule.

 

[kiz88]

There back in stock on the Sprint website, just ordered my new one from Sprint and a return kit is already on the way.

My phone ships today should have it tommorow or the next day, ill post up how it works as soon as I get it.
