Screen acting weird

Hi,
I have been using the x 10 for about a couple of months now... one thing I don't get is why the screen goes all weird on you and randomly presses buttons if you have moisture in your hands etc. For example if I get out of a shower and start using my phone, it never presses the keys I want it to press, just randomly presses all the buttons. Sometimes I hit the backspace and it doesn't stop even after I take my finger off of it. Tries to erase the entire line. Even if I have some sort of dirt or dust on my fingers and it comes in contact with the screen, same thing happens.
So is this something that is happening with all of your phones or just mine?

I guess this is a property of capacitive touch technology. Happens on my synaptic trackpad all the time.

really? it never happened on my other phones even though i had capacitive... i do agree it happens sometimes with my trackpad as well, but not to the level the x10 does... heck if i get close the screen and blow on it the damn thing will start pressing keys... ever had that?

It was just a guess. And I've just tried blowing hard on my X10's screen, didn't work

hmm... damn i cant even exchange my phone... it doesnt have warranty

I noticed the same issue. To fix it i put on a screen protector (i took off the stock one) and updated to 026. Its been a week with no problems.

been having same problems....from call log...i ll dial the wrong number.
when i type something,..the keyboard will totally type out some different letters.
especially when hands are moist..which they mostly are...not wet..just moist.
doesnt happen on iphones at all.
thinking of changing the stock screen protector

I have experienced something similar, but not as extreme, when I have damp hands.
Removing the screen protector did cause an issue for a mate regarding over sensitivity.
Capacitive screens certainly do seem to prefer dry skin though.
Swyped from my rooted X10i using XDA.

i have the same problem but mine is with the stock screen protector on, does any 1 have a fix yet it really is driving me mad to appoint its nearly went out my bedroom window!!

It does happen on iPhones (both first and second gen) owned them both and it was pointless to even attempt to use it. The only fix is to keep the screen dry.

sometimes can't unlock the phone with the slider

I have an ATT Streak, with the Dell 2.2 froyo installed and updated. With the stock 1.6, the initial 2.2 and the updated 2.2, sometimes I can't unlock the phone. The green unlock tab will not slide across the screen. Most of the time it's fine but it happens at least a few times a day when attempting to answer calls. I've found that I can get it to unlock if I move the slider enough to reveal the white dot under the speaker icon, and then press that. Pressing the dot under the speaker icon makes the unlock slider move all the way over so I'm not dead but it's still rather frustrating. Usually everything is fine. Anyone have any ideas? This is my first Android but I've had Kaisers, Raphaels and Rhodiums and have gone through a fair amount with them. Do the DJ_Steve ROMs fix the problem? Is this a known issue?
Thanks in advance

See thread 'Touch screen unresponsive after pocket time'

You can also get Menu unlock from the market...it allows you to just tap the menu softkey to unlock the phone.
Also, check out NoLock from the market...you can have it set so that when you hit your power button, your phone opens to the homepage.

I had exactly the same problem, would miss phone calls as I couldn't slide to answer either. This happened almost systematically when I left my wifi hotspot - but would happen also if wifi was turned off.
In the end, recalibrating my screen did it. Since, I haven't had a single sticky/frozen slide to unlock

calibrating did not help but returning it did
I couldn't make myself think the phone was worth the troubles so I brought it back and went back to my old Tilt 2/TP2 while I wait for the aTrix or a slider version of the 4.3" HTCs or Samsungs like the Epic. Thanks for the advice.

Try "easy answer button" off the market, it allows you to have a button to answer the phone.

Touchscreen out when in pocket

Agreed, see that thread and remember to make sure the touchscreen is facing away from your body when you place it in your pocket. Something about the heat/magnetic sensitivity that get's thrown off when it's in your pocket and facing skin. Worked like a charm for me...no issues with unlocking or touchscreen responsiveness...

It's the static build up on touch surface; not avoidable totally but above suggestion would minimize it to non annoying level... antistatic pouch would also help no matter how it is carried.

I've delaminated the resistive screens on a bunch of HTCs
carring them in my pocket screen in. I thought the glass on the streak wouldn't have any of those issues. I'm leaning towards an aTrix when it comes out and I think it's also gorilla glass. You think it's the heat, or static that causes the problem?

I also had this problem, and it got solved when I uninstalled my App Killer!
I have a Q, since I cannot find "menu unlock" on the market, can I download it and install it over PC (without rooting etc.)
I'm using froyo 2.2 official 318 build

Recalibrating it did the trick for me

Gorilla glass is a chemical treatment to harden glass not really helps or solves static build up like issues.. I am guessing top layer glass is very thin on streak (lowest margins are .5 - .75mm for tempered glass and even less than .5mm for polycarbonate surfaces) hence the static build up, which is impossible to prevent, rather easily interferes with streak's touch sensor. There are safety margins for gaps between LCD and touch as well as touch glass thicknesses for proper signal capture by adc before fed into touch controller (if discrete IC is used) and there is a big chance streak design took the lowest possible of those margins and since the surface is rather large, static build up could temporarily hinder touch recognition...

Recalibrating fixes this issue and its not due to gorilla glass or due to storage of the phones in your pockets.

Just b/c it worked for you doesn't mean it's the only answer. Recalibrating did not fix the issue for me. Changing the way I carry it in my pocket *did*, but that doesn't mean it will solve *everyone's* similar issue. We're just trying to help by providing suggestions...

[Q] My HTC HD2 is going berserk

Since about 2 months, my HTC HD2 sometimes runs into a strange behavior.
It's like some invisible fingers are touching the screen very quickly, triggering apps, menus, and sometimes calling people!
The only way to stop that is to restart the phone (but when the HD2 starts to behave that way, it's difficult to restart it, as these "invisible fingers" are still competing with MY fingers!).
I don't know what caused the problem in the first place, and I don't know what triggers the problem when it happens.
Is my HD2 out of order?
Thanks
Gz

It could be that your touchscreen is too sensitive and your sweat from your fingers is triggering it; Did you try cleaning the screen, your hands and using a screen protector?

your digitizer is going to die very soon

By "digitizer", you mean the touch glass?
Did it happened to you before?
Why so many of your phones had their glasses cracked?
Thanks

It's very probable to happen...

Try to massage the screen around the corners especially above the buttons.
There is some kind of "glue" to prevent contact with metal but if its old or used it could make this problem.
Maby you can trigger it or at least find the point where to press to make it stop.
=> using a heating fan (warm not hot!) to vaporize water could help too maby. No warranty here!

dertester123 you may have found the real cause of the problem, but I'll have to test more before I can confirm.
Cheers.

i have been having the same problem lately and i must say, i'm pretty sure it's about the sweaty fingers! i have read on other sites that the capacitive (?) screen is too sensitive and that many are experiencing these problems, especially during summer!

Just place some waterdrops on the display or use it with fingers that you put some lotion on....
Problem is when it gets under the display, but thats rather uncommon i hope;D
I case its just just sweaty fingers, what are pants for?

I have the same problem but it only happens in my music app. Could this be causedby a virus of some sort?

are you running android ics? In ics they changed the input slightly i heard, and maby its not ported correctly...
When using another music app or switching to generally other apps while music plays everything is okay?
I dont think its a virus or something, most of them want to spy or change userdata and not annoy you

I thought I had found the cause of my problem, but I can't confirm it, as this problem hasn't appeared since the middle of May, when I followed dertester12's advice to massage the screen on the corners!
But I noticed a spot in the middle of my touch screen where the "glass" seems to "touch" or to be glued to something underneath it. This spot is till here today, but despite of that, the problem is not occuring now. I'll try to attach photos of that.
So to sum it up, I'm still not sure about what caused the problem...

What it could be the cause of this behaviour?

Well the touchscreen must be isolated from the display. Therefore they put some blue glue at the area over the buttons where the HTC logo is. For me I used alcohol to clean the touchscreen as I replaced it and had the problem that when pressure was added the layer of glue was to thin to isolate and gave me fake inputs.
You can test by massaging this area.
Also the contacts on the backside of the screen must be isolated to the housing and the screen. I could think that when you soldered the stock isolation thinned out too..
Last but not least touchscreen, display and housing must be grounded correctly. Therefore all parts are wrapped in metallic foil at the edges... To connect them..
As the touch screen is very sensitive to even little currents its often hard to find the problem as it could also be a totally different cause.
All the above mentioned points should be checked and are relatively easy to fix. But it needs total disassembly what - especially to old devices- has a risk.
Risks are:
That damn flex cables are old and tend to break. The buttons have small tapes on top that come off easily and never go back again... And many more things that break when dis- and reassembled to often.
Sometimes it's cheaper to sell defect HD2 and buy new/used one..
On eBay you often get very good prices for defective HD2..

KnockOn not working while running with armband

I am using my GS4 running armband with my G2, it fits well actually but there is one MAJOR issue. The phone will NOT wakeup when double tapping the screen. It will however turn off when double tapping the status bar. Has anyone else gone running with their G2? If so how has it worked out and what armband are you using?

Be sure the proximity sensor isnt covered, if this is covered it doesnt listen, probably to prevent from turning on in your pocket.

The ar band I am using doesnt cover it, I wonder if maybe its too thick and is possibly messing with the sensor?

KnockOn is also affected by the orientation of the phone. If it doesn't detect that it is in an appropriate orientation for typical phone use it will ignore the KnockOn feature.

I have tested that, it turns on at all angles and even upside down. I don't think that is very accurate, even if LG advertises that. I am guessing my arm band is too thick.

Just got my international version yesterday and was really bummed to discover the same issue this morning.
It definitely has sonething to do with the proximity/light sensor next to the LED getting thrown off my the plastic of the armband view area.
I experimented by pressing the plastic flat against the phone and it then worked. Obviously not practical to try and do while running, but its a start. I imagine that, while not ideal, cutting a section from the armband window may help
Will post if I find something else

Tips-Knock immediately unlock

If you didn't know, yours G3 have possibility to directly unlock device from black screen, if you have a knock code activated.
Just tap a knock code on black screen and voila.

No way!

water is wet

If you press the button on the back it wakes the phone and if you press the buttons either side the volume will increase or decrease (I will leave the excitement of which button you press for the desired effect a mystery for you to find out for yourself!)

Aww he was just being helpful...lol probably first knock device. I was pretty excited with mine too, kept "knocking" it all day lol

I honestly turned off this function on the G2 and G3 out of habit... is it better on the G3?
On the G2 my pants or thigh keep unlocking the phone... I guess don't wear skinny jeans with this phone?
Maybe i'll turn it back on and try again to see if they improved anything...

I put it in my back pocket and have Cerberus emailing me, informing me my bum cheek was trying to crack the knock code.
But back on topic... 5 years to post one topic about a well know feature is quite poor, this dude has racked up 40 tips:

a little thing i noticed about the knock feature is that the grid size doesn't matter! I've been messing around with it all day and love the fact that I can make the pattern very tiny and to the right (since im right handed) and it unlocks flawlessly!

It only works if there's light. I've never had trouble when in a dark room, but if I'm holding my phone landscape and double tap to wake, it doesn't turn on if my hand is over the light sensor. Took me a while to realize that was the problem - I thought it wasn't working right.

wow.... just... wow...

Anyone else try to wipe their screens with a micro fiber cloth and the phone turns on? It does It every time.

Yes, with anything really - a paper towel, a shirt, a microfiber cloth. If my finger heat happens to touch the screen twice, this will happen. If I hold the cloth down hard, it won't happen.

With the screen off, if you hold down the Volume Down button for a few seconds the phone will open up in camera mode.
