[FIX] [UPDATED] Touchscreen issues
This here is a very serious issue, with a rather simple solution. I'm talking about the issue where the
screen becomes unresponsive in the following ways (these are just some of them): it takes more than one attempt to move the lock ring, not every press is registered when typing, buttons at the bottom of the screen don't always work, you can't get the carousel spinning, hectic touch issues while charging.
UPDATE YOUR FIRMWARE FIRST
Before proceeding with any hardware "manipulation" I recommend you
try the latest firmware. If you are running a stock ROM simply update your phone's software, and if you are on a custom ROM the update can be found
here (you already have this firmware if you are running ICS).
If the issues persist, keep reading.
IMPORTANT
You have to realise this fix does not solve the issue for everyone. So just to be clear,
THIS DOES NOT SOLVE THE ISSUE FOR EVERYONE. The reason for this is simple -
not everybody has the same issue. My opinion is that these issues have similar symptoms, but the causes are different (prove me wrong if you know something I don't).
The issue addressed here relates to a small
silver pin located at the back of the phone (pictures below). That damn thing is the screen's "grounding" connection to the back cover (more about that in abrown0809's post
here). In time the
pin starts loosing proper contact to the cover, and the screen becomes unresponsive. There is also a matter of static build-up caused by this, which further complicates matters. I believe this is mostly down to the worst back cover in the known universe.
This issue usually appears for apparently no reason, but you might also experience it after
dropping the phone, sneezing too hard, or after installing an aftermarket battery (Anker, Chichitec, etc.), since they are usually thicker.
A thicker battery could further loosen the already loose connection between the cover and the pin. If you only have issues
during charging try a different charger. If you still have issues, this fix should help.
Note that there is
more than one way to fix the issue, and that the results are
not always instantaneous. The simplest fix is pulling the aforementioned pin outwards. The downside is the pin might bend back into its original position... So you could try applying one of the alternative solutions as an addition to pulling the pin out, or simply doing the alternative only.
Also,
I am not responsible for your actions. If you damage your phone, it's on you.
CREDITS
What I am doing here is sorting useful info and adding creative advice, I am not the one responsible for the actual solution. It's primarily
tinky1, who started the first
thread on the issue, where most debating and solving was performed. Then,
misiek_to_ja (and his daughter
) noticed that using the phone without the back cover temporarily solves the problem. This meant the problem was beneath the back plate, which
abrown0809 proved by pointing us to the
grounding pin that everybody was somehow missing for two months. What followed were aluminium foil and soldering
tricks that
eliteone thought of.
stuart0001 started a
petition that I hope HTC noticed, though they remain silent.
Andyjb103 pointed out that the firmware update can fix the issue in some cases. And there is of course everyone from
tinky1's thread that went through loads of pain and suffering while testing different chargers, wall sockets, USB plugs, area codes, weather conditions, etc. THANK YOU ALL!
Now then...
THE FIX
Firstly, the simplest way to fix the issue. Switch the phone off, remove the back cover and locate the
silver pin shown in this picture.
Now
pull it out a bit, like so:
Use a needle, a tiny screwdriver, or anything with a pointy end. But
be careful. Don't pull too hard or too much. The side of the pin that is closer to the edge of the phone is the side you want do the most pulling to.
And that's it as far as the pin goes! Results
could be instant, but there is still a chance you'll need to do a couple of things:
1. Discharge the phone all the way (until it shuts down).
2. Remove the battery and press the power button (as if you were trying to turn the phone on).
3. Leave the phone without the battery overnight (or for at least an hour).
4. Put the battery back and charge the phone
without touching the screen.
Make sure you don't touch the screen whenever you're charging, until the issue disappears. This should happen within 2-3 days. If the problem persists, you ether did something wrong, or (as explained above) you have a different issue... Most common related problem is a faulty digitizer.
If the issue does go away you could
make sure it stays that way by applying one of the alternatives as well.
ALTERNATIVES
See this small white
square on the inside of the back cover?
That's where the silver pin makes contact to the cover. By pulling the pin out you insure better contact to that square. There are plenty of ways to further improve that contact.
Here is a few:
1. Take a small piece of
aluminium foil (5cm by 2cm, or whatever works for you), fold it over a couple of times and put it over the square (like
this). Now carefully put the phone into the cover and make sure the foil doesn't move away from the square. If you want to keep the foil in place add a drop of
superglue (just not directly on the square).
2. Alternatively, the foil could go
directly on the pin. Stuart0001 made a picture of that
here.
3. Adding any sort of aluminium works (or
any conductor for that matter). Take a look at what Oceanic72 did
here.
4. Put a few drops of
solder onto the square. And be careful with this one... Or just skip it if you've never soldered before. More on that in eliteone's post
here.
5. Put some
electrically conductive paint on the square. Michael_Mcr suggested that
here.
There you go
If any of these solutions solve your problems but they come back, just try again. I do not recommend puling on the pin more than a few times though...
Hope I helped!
