So I'm having this strange problem where optical trackpad seems to get some kind of input during certain lighting situations. The screen sometimes scrolls by itself and also when Im typing on the physical keyboard, the cursor moves so my sentences get really messed up and I have to move out of the room to type. The physical keyboard and haptic button lights also turn on and off for different periods of time.
This only happens during certain lighting situations and one happens to be when Im my room. I have changed the display timeout to different amounts, changed screen brightness (auto too) and also have done 2 factory resets. Still having the problem. I hope it is just my phone because otherwise, I love it. And I hope Radio Shack won't charge me a restocking fee.
Anyone else experiencing this?
Note: I do have a video link of this, but I can't post it because I'm a new user
G2 trackpad is optical so it's susceptible to stray light:

So thats what was making mine do it i find it also happens the more you overclock the cpu for some reason
Try clean it with a microfibre cloth ,it worked for me

Maybe your light sensor have problem, try to clean it and reboot??? or just flash another ROM, your current ROM may cause this

Its just the oversensitivity of the trackpad. When its dirty and light flashes over it, it interprets it as finger input. Its not the ROM.

I've got the same problem. Generally it happens when I'm at the office and sun shines through the windows behind me. When it happens I hide the trackpad with my finger.
But yeah this optical pad s*cks, and I miss the old trackpad with the tiny ball that I've got on my G1, even though it can get dirty because of dust.

Same thing with me. When at work, especially in the morning with the sun at my back the G2 has a mind of it's own!
Works fine for me in sunlight so long as it isn't cover with greasy man prints

too bad it's a input method im thinking if i where any good at hardware modding i could disable it somehow maybes theres a way to via software i dont feel like hauling out my soldering gun
My trackpad seems to just go mad periodically, it doesn't seem related to light sensitivity or dirt. It drives me crazy, and I never use the trackpad -- is there any easy way to disable it?
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...

No lock works great. The lock screen is a pain in the assets anyway

hi, i was bored and i put my desire z in my friends blackberry messenger case with a magnetic latch. when i pulled out my desire z, it seemed to have turned on. After further inspection, i found out that if you slide a magnet behind the desire z slowly, it will wake the device bypassing the lockscreen. I just wanted to share this with everyone
Be careful with that magnet I have a feeling that could really mess up your phone if its strong.

I don't think it would be that bad unless you had a really powerful one. The phone already has some sort of magnet or magnets in it. I'm a welder and have found steel filings bunched up all over the place on it.

well its a small magnet in a messenger case. i doubt that it would be strong enough to screw up my phone also i dont know if htc intentionally put a magnetic wake in their phones or not?
I have the same issue... and it wakes as the slider is opening.
Then the magnetic field probably interferes with the slider mechanism/sensor

This is not an issue. Also when your keyboard is open, your phone turns on because it senses that the mechanism is open/ moved. this is supposed to happen. htc designed it like this so people could text easier without having to push the power button

I think you didn't undertand my statement
My issue is: when I put my Desire Z over the magnetic case, it thinks the keyboard is opening (same as you described).
Also bypass the lockscreen, as the keyboard opening.
I know that when I open the slider the screen goes landscape, it obivious.... the issue is when it happens when it is not suposed to.
it could also depend on that the capacitive touchscreen works like this: when u put your finger on the screen and have contact with the metal backside of the phone the magnetic field of the screen is interrupted and recognizes where your finger are, maybe the magnet from the case makes the screen go haywire because of the magnet?
Just a theory..

no i dont think so. when i slide the magnet over the back of the phone, im grabbing the sides of the phone, not the screen or back.
I really cannot figure out this issue I'm having. Basically, I have the black rubberish/flexible case that T-Mobile sells. Once in a while, while using the touch keyboard ( stock gingerbread, I'm using cm7.) A couple letters become unresponsive. Most work, but others will not.
Weird thing is, when this happens and I take the case off, all goes back to normal. Maybe I'm missing something here, but how could the case cause this?

Maybe the case is applying pressure to the device and for some reason making the screen less responsive. I have this with my TPU-S Curve case and the one with the kickstand on it.
I actually believe that is a CM7 bug. I have experienced the same problem on recent nightlies. Some keys on the keyboard will go unresponsive, while others will work. Occasionally the entire keyboard locks up. Once, the keyboard worked but the image of the keyboard didn't show up (tapping in random spots on a webpage resulted in text being typed, lol).

Everyone experiences that in any rom, even stock, once in a while. The point is, some letters work, some dont. The ones that dont work usually are not even close to each other. and EVERY time it happens, I take off the case and it goes back to normal.
As for the theory that the case was causing pressure, the chances of that are slim for two reasons:
1. It hardly even reaches over the glass. at most, a couple millimeters. http://www.t-mobile.com/shop/AddOns...48e2-bb7a-0e5d354aefa7&inCart=True&catCode=21
2. Being a gel skin, it doesn't really cause pressure to the phone at all. (I could be wrong here, it just seems unlikely.)
This just baffles me because I KNOW its the case causing it but I can't begin to comprehend why.

Just for kicks I tried applying pressure to the edges of the screen using the gel case while typing. I also wiggled the phone around in the case so I could test all positions, all while typing away and nothing could reproduce the unresponsiveness.

I've come to this conclusion as well. The only thing keeping me from ditching the case is the fact that this is one dang slippery phone.

Yeah that's true and I like the case to protect it when it falls.
Perhaps the gel case is electrically conductive? I noticed one day I was caught in the rain and some raindrops fell on my touchscreen, which caused random things to be selected until I wiped the water off.
It actually might not be the case... The myTouch 4G's screen has random spots that die temporarily for no reason, and keeping away from the screen or locking and unlocking it can revive the spots. It's not the case at all, probably just the time it takes you to take off the case that the spots revive and convince you that it's the case. Try letting it sit for about 20 seconds when the screen dies and see what happens.

When at home I use the phone without the case quite regularly. I've never had this issue when the case isn't on.
In fact, I can usually (Without taking the case off) go back to the homescreen and do stuff, all spots being responsive, while the keyboard is acting funky. The keyboard itself has the issue but nothing else, even when using the same touchscreen spots.
It's such an odd correlation, the keyboard software itself and the case. Yet there has to be something that one does to the other.
Also, just to make this clear - this ONLY happens to the keyboard. If that theory was correct I would experience this in any app
I noticed this also when I first bought my phone, bought the rubber case the same day. after a couple of months, the letters towards the end of the keyboard would become less responsive and I had no idea why. took the case off and it went away. so I ditched the rubber case and got a TPU, never had the problem since then. I think over time the rubber case gets a bit stretchier and bigger, causing you to have to sort of roll your finger around/over the case to press the keyboard buttons on the end(unless in landscape mode)
You know I've always had this problem, and I thought I was the lone soul that had this retarded hardware (maybe software?) issue. I was on Royal Ginger 2.1 and never had this problem. But then subsequently left RG and started using ROM's like Virtual Fusion, MIUI, Virtual Unity, CM7 RC1 and other CM7 nightlies and all of them I've had the problem where some of my keys would just stop working, most noticeably the "delete" key. Other keys like the letters "P" and other vowels would cause the same problem as well. So I figured it's just another list to add on to the plethora of hardware defects that plagues this phone. I've used several KB's as well such as Flex T9, SwiftKey X, SmartKeyboard Pro and even the stock GB keyboard and problem still persisted in all of them.
So I thought what the hell might as well flash Royal Ginger 2.1 to see if the problem is still there and after 2 days I have yet to encounter it! So now I'm baffled... I was for sure that it was hardware related but now I don't get why it's not happening ONLY to Royal Ginger...
I have had the same case on my phone, it's a TPU case. I know it is not the cases' fault as it's always on my phone even now when I'm on RG where I have yet to experience that problem even once.
So I'm pretty much dumbfounded...
I don't think it's the case. I thought it was a ROM thing... agreeing with mackster on this... haven't had a problem while on RoyalGinger 2.1, but have encountered it on CM7 RC1, MIUI & Virtuous Unity...

My phone will switch to landscape orientation when completely closed. I can finally get it to switch into portrait by SLIGHTLY nudging the screen to the right. I've been having this problem ever since I got my EVO Shift around June. It's particularly annoying because it causes the screen to wake, and my phone is usually in my pocket causing it to move around. I often find my phones display is randomly on when I pull it out. It causes even more problems when I'm listening to music.
I want to know if anyone else has experienced this problem and/or if anyone has a suggestion/knows how I can fix this issue myself.

What Rom are you using? Are you rooted? You can disable Auto rotate. Menu-Settings-Auto rotate , and uncheck it. But it should not be rotating on the home screen unless you flashed a mod to do so.

Changing that setting does not do anything. As I stated in the title, this problem is related to the hardware keyboard. The mechanism that detects if the hardware keyboard is open or not is malfunctioning. It's detecting that it's open when it's completely shut, thus causing orientation switch.
EDIT: Just to clarify, this has happened on multiple roms. Stock 2.2/2.3, CM7, and MIUI. I'm currently running MIUI. I just want to avoid turning to Sprint to fix this issue ;(

Run G-Sensor calibration (bubble level in market if not on sense) and see my CM7 optimal settings thread here:
http://forum.xda-developers.com/showthread.php?t=1262313
Basically want only 0 and 90 degrees of rotation. That should help.
If it did it on the stock Rom unrooted, than I would have to say it's a hardware issue. If it started after you rooted, than I would just RUU back to stock and see if that fixes the issue. But you might as well try the RUU if you have to take it back to Sprint anyway. The Froyo 2.2 RUU is HERE if you do decide to go that route.
I'm positive it's a hardware issue. I can't remember exactly when I got my Shift, but it was stuck on 2.3 OTA. The problem was occurring then and is still present on all the custom ROMs I've tried so far. I guess I'll just have to take this thing up to my Sprint repair store ;(

I'm not absolutely sure about the shift, but I know a lot of phones "read" the position of the keyboard by magnetic movement. Your magnet may have come loose. Any drops you remember? Very possibly. I wouldn't sweat taking it in if you have a repair store near by. It should be a quick fix.

I was thinking a case may fix the problem and/or prevent future problems. I've been looking at the OtterBox Commuter case. It's on sell for $21.85 on Amazon, but I'd like to find something a little cheaper. Any suggestions on a good, inexpensive case?
