^^^^^^Looks like its related to infamous motherboard issue. Do you get random reboots under stress by the chance? I had my mobo changed.

Opposite grounding problem ?

---

I am having the same symptoms, I am unable to use 4 main button below the touch screen, but i am able to use the touchscreen fine. This happen 1-2 weeks ago, since I purchased it last June.

I tried one of the solution by lifting the silver pin and additional aluminium foil but it still did not worked, until I realized it was the opposite!!

Testing the same test as the youtube video.
If I put the HTC Sensation on the table, and touch the 4 button, it works.
But as soon as I touch the body and touch the 4 button, it did not worked!

I tried to isolate the grounding (literally with a cellotape), it still the same!
I think it is because there are still other golden pin that connects the body

I've factory reset, and tried different ROM. And even do a key test on the recovery mode. I conclude this is a hardware issue, and this grounding might be the issue.

For now, what i see as a workaround is to make sure that I did not touch the body when I use the button, by using a case (which I dont have yet)

I might add pics and vids later

Ok I definetly have problem with the unlocking. Besides that thoug once it unlocks its perfect . Zero problems.

Sometimes it unlocks just fine and as if there were zero issues.

Such an annoying little problem.

@claud_face:
That's how the issues start usualy - with the lock screen. You could try what I wrote in the first post:

4. Put the battery back and charge the phone without touching the screen.

Then do not touch the screen while charging for the next couple of days. And also, pull the pin out a bit more before doing any of this
If it goes away, there you go. If not, you messed up something else...

@akusuma:
The only thing I can suggest is the same thing I just suggested to claud_face. Doing that discharges the static and might help

Ok so if my problem is the static thing are you saying this is a hundred percent garanteed method???

Why would some people have this and others wouldn't?

Besides the grounding pin which makes sense but did.t help in my case.

Thanks.

I know I'm repeating myself, but to know for sure if you have static electricity (grounding) issues you should do the same thing I suggested above. If the problem goes away you can start looking for a way to ground your phone.
If not, you might have a faulty motherboard, like tinky1 suggested. It does seem Desires in general (including Desires S and Z) have a really touchy motherboard :|

I'd say 99%
The method I posted is a modified version of what we what we came up with in tinky1's thread quite a while ago. That's the method most of us used before we found the silver pin.

So, if you do it properly (repeated charging with NO TOUCHING ), the issue will go away. If it doesn't, the sun fried something...

Yup, using it myself and other users reported success. The process discharges static but DOESN'T fix the cause.
Read op and last 5ish pages of my thread.

thanks guys,

I will do the steps and let you guys know if problem went away.

When Im recharging does it matter if phone is on?

And when u say not to touch screen could I touch the case?

Like I should unplug from charger adn then I could touch as much as I want right?

Thanks alot guys.

Doesn't matter if it's on or off, try not to touch it while on charge unless you have to. Then touch as much as you want. Problem might not disappear right away, 2 or 3 cycles might be needed. Good luck.

Yes, it can be on, and yes, you can touch the case. Once unplugged you can use it normally


edit:
tinky was a minute faster :P
