Phone turns off about once a week

The subject heading pretty much says it all. I think about once a week I'm coming to my phone, pressing the power button to wake up the screen, and I'm finding that the phone was totally off.
Just the other day it happened twice. Never happened before, and it may be a one off.
But am I just accidentally taping power off (which I'm pretty sure I am) or am I going towards making sure my backups are current and getting a replacement (no doubt referbished) Desire?

Perhaps it's a 3rd party application causing the issue?
I'd suggest you do a hard reset and see if the problem comes back.
It's pretty difficult to accidentally power off your device. You still have to go through 2 screen taps to power off after you long-press the stand-by key.
Get it exchanged if you've ruled out any 3rd party applications.

This happened to me for the first time yesterday. Left my phone in the glove box of my car, came back and it was turned off. It would turn back on either, I tried for ages in a mild panic!
When I got home I removed the battery for a bit and then it suddenly worked.
All been OK since.

I was thinking about 3rd party applications, but haven't started investigating. Probably because of the frequency it occurs and the amount of apps I have. Though I think I only have pretty popular apps.
I did a post a while ago that I had dropped the phone in a very minor way that would not have broken a Jacobs Cream Cracker (if you don't live in UK, they are very fragile, brittle, biscuit type things). But on each of the two times, one of them being a very cushioned landing, when I picked up the phone, it was off. I was thinking that this must have been what happened. But I'm now thinking it was either a separate issue or coincidence because I don't drop the phone and it still is sometimes off. And I think this occured before even the minor falls.
Hmmmm.....

I just did a test and dropped it from exactly 3cm flat onto my desk and it was instant off. I should add that I have a silicone/gel tight case on my Desire.
Like I said before I don't think this is the main problem, I think this is a secondary issue. And as I've said before, I think the phone going off from this sort of a drop/shock is too sensitive and delicate. Maybe sometime is not quite as tight as it could be in other people's phones.

Perhaps the body of your device is a bit warped such that the battery is a bit loose. That would explain why your device would power off from shock. The battery contacts may have shifted.
Try this. Take off your battery cover. The battery contacts should be on the left (the side without the volume rocker). Try to leverage the right side (the side with the volume rocker) of the battery so that the battery remains in contact with the device. I would try to slip thin strips of paper on the right so that it pushes the battery to the left.
Then try your 3cm drop test again. See if it improves.
If it improves, you can choose to continue using this method (despite how ghetto it is). Or you can see if you can get it replaced under warranty. Don't mention that you dropped the device, of course!

Other issues (like the glovebox fellow) could be related to heat, too. If it's too warm, I wouldn't be surprised if it turns off and doesn't turn back on until it's cooled down.

The phone has never yet failed to turn on the instance I've pressed the power button.
Looking into said ghetto method....
Nope. Contacts on the phone are all sprunt and sticking out nicely to meet the contacts on the battery, which will then compress the sprung contacs. So I doubt pushing any of the contact out further will help.

Is there any sound meant to come from the phone when you shake it? I don't mean furiously shake it, but just a milding shaking by your ear.
I have always heard a small movement but had assumed it was the vibrating mechanism.

Its the camera lens (internal focus part). Its like this on all HTC devices due to the lens they use.

Touchscreen Digitizer Issues?

So lately I've been having problems with my DI2. Occasionally, when I unlock, it appears to receive what it thinks is a touch at a lower portion, usually around the middle of the lower portion, of the screen, and this results in things like Home being activated, or the app drawer. This will happen even if no part of my hand is near the bottom of the phone (front, back, and sides).
More recently, it has become and indication of random touching on lower parts of the screen. I've had it completely freak out and type random stuff in input fields. When it gets really bad, the touchscreen stops responding, but I can lock and unlock to get it back, usually.
This has made typing in portrait mode quite difficult, and it's becoming very annoying.
Is my touchscreen digitizer failing, or is it possible there's some sensitivity adjustment I can make? Is it possible it's related to static or something and I can use a cleaning solution or something to correct it?
I really want to avoid paying a lot to fix this issue. I've already seen places where I can buy a replacement digitizer if that is needed, but it's not cheap. I'm really hoping this phone will hold out a lot longer than it is right now as it's been an otherwise good phone.

You may want to try recalibrating your screen.
Go to Settings > Language & keyboard > Touch Input > Text input > Calibration tool.

i think this only calibrates the keyboard. there is an .apk around somewhere that will calibrate the touch screen, some roms have it built into the settings.

Well, I'm not having much hope with calibration apps. This looks like a very device specific thing, which is understandable. Besides, it doesn't really feel like a calibration issue. When it's not going haywire, touch accuracy seems fine.
I'm not really keen on going for a replacement. Besides, my physical modifications (antenna improvement, improved access to power button, etc) may prevent that
If I can't find a cheap/free solution, I'll just jump on replacing the digitizer. This is not a task that bothers me, was just hoping someone came across this issue and found a better solution.

Harbor Freight has the hot air blower for $12.00.

This may be a dumb question but i didn't see you mention it. Did you try a factory reset? Perhaps you have an app or something conflicting with screen response somewhere in there.

I seem to have dead spots once in a while on my touchscreen. Doesnt really effect day to day usage but can be annoying when trying to click something. Like a link on a webpage, sometimes I will have to scroll up or down to move the link before Im able to click it.. spot seems to be centrally located but has happened in a few places.

Not a dumb question at all. I did not mention it, and it's completely valid. However, I have gone through a couple of full resets since the issue started, and the behavior has persisted.
In fact, I have tried a couple of different firmwares in the time it has started. I had thought maybe a build of CM7 might have caused it, but the ICS builds have the same behavior, as well as a couple other firmwares that I don't remember the name of offhand.

For me, it's not an issue with dead spots. For one thing, the issue is intermittent and in varying degrees of severity. Usually when it happens it's just something at the bottom activates and I can cancel it out and carry on with my session. Occasionally, though, it just goes haywire, as though a palm is resting on it or something is touching random places rapidly.
So far I've been able to kill the haywire behavior by locking the display, wiping it down a bit, unlocking the display, then continuing on. I haven't had to take any more drastic measures than that. It's still annoying in that it can happen while typing a message and I have to go back and clean up the mess it leaves, or it might monkey around with an app.
It seems as though there might be some static buildup or something because it seems worst shortly after taking it out of my pocket. If that's the case, I wonder if I can ground it out, or do something to dissipate it.

Sorry i didn't notice you mention it anywhere. Fwiw i get lockscreen issues kinda like you describe. i use the slide lock on cm7 and when i go to slide right to unlock, before it gets to the dot the lock releases without me lifting my finger. I know i don't have a dead spot because it only does it on the lockscreen and relocking and waking the screen fixes it. Only happens on cm7 and why i thought it might be an issue like that.

If you need to replace the screen/digitizer you will need to heat up the glue to remove the screen. Normally a heat gun is recommended

Bro I just went thru the same thing same week. And I've tried all the suggestion here, in the end it was the digitizer. I call Verizon and explain the problem and they are sending me another Dinc2. It sucks cause now you have to unroot and restore (s on) (which for me was a bit of a *****) to send the phone back , but trust me at some point the entire bottom part of your screen will not respond to touch.. You'll only be able the answer calls from the lock screen and to hang up you'll have to do so thru the pulldown bar. And the biggest problem will be you won't be able to access your key pad. Sorry bro but thoses are the facts....I'm waiting for the replacement as I type this.

It's not held in with a normal ribbon cable lock? It would be strange if they used a glue. I've been inside many of these devices in the past going back some 10 years (including at a repair center) and didn't face glued ribbon cables (either solder or ribbon cable lock).

They are held in with a ribbon cable lock but the screen and digitizer are glued onto the phone itself, like the metal part that holds all the parts

So I wasn't able to find a software solution. Not sure what's causing it, but it's causing some unwanted issues (hang up call and it immediately calls someone else based on a false touch). I ordered the parts I need and will report if this fixes my problems.

Where did you order from, how much did you pay?
Be sure to watch both of those vids on utube.
I live where the relative humidity is around 15% most of the time.
Still I notice that when I pull my phone out of my pocket, it has moisture all over the back where it was pressing against my leg.
I found putting it in a soft cover pouch keeps most of that under control.
Just for the heck of it , try putting the phone in a jar of un cooked rice for a few hrs.
Battery and cards removed, jar sealed tight.
If you have another phone to transfer your calls to that would be better.
If you are like me and your skin oil transfers to your phone allot, use a fine tooth brush around the area where the screen meets the housing.
Avoid pushing any debris further into the unit. Use brisk outward strokes.
If none of that produces any favorable results, look for a hot air gun or a blow dryer.
Keep us updated...

I've worked in microelectronics in the past and know quite a bit about moisture control, static control, etc. I had to help manage a sizable clean room at one point.
Unfortunately it's possible that my digitizer is just flawed and the flaws are just now coming out. I don't think it's moisture, but rather most likely electrostatic. I live in a rather dry place.
I normally would not use a screen protector, but I might consider it now as it might add an extra layer of insulation from static in my pocket.
The digitizer I found was from a seller on Amazon. For all of the parts needed (I don't have the tools for properly working on this device), including the small double sided tape, I spent around $32.
The double sided tape comes in a big roll so if anyone else needs to do this kind of repair, I will ship the remaining tape for the cost of shipping (this should save you about $5).

[Q] Is my Incredible 2 overheating?

Hello all,
I purchased a used Verizon HTC Incredible 2. I've been playing around with the phone and everything seems to be functioning, but after 10-15 minutes of use (basically when the screen it on while I'm playing games) I noticed that the lower portion of the phone seemed to feel a lot hotter than the rest of the phone. There is definitely a difference in temperature between the upper half and the bottom half of the phone.
As I said before everything is functioning as it should, but there is a little quirk that I noticed. On the bottom of the phone there are 4 shortcuts (home, menu, etc.) When I have it in the vertical position I can see a faint image of what the icon should look like when I go into the horizontal position. I've included a picture (the best I can do) to illustrate what I am talking about. My assumption is that this is the cause of the 'overheating' because both lights are on. Maybe it this isn't even the cause of my so call problem. I'm just afraid that this issue may cause issues in the future.
Edit - So I can't seem to post links...
Downloaded OS Monitor, this app is telling me that my battery temperature is 38.1* C or 100.58* F

I have noticed this on mine for the first time yesterday. Extreme heat on the bottom right side of the phone. Everything works ok except yesterday I also updated my PRL and it changed. Ever since I have been having LOTS of jumps to 1x data where I always have 3g. Not sure if the problems are related.

Our phones can tolerate up to 115F then the notification led will blink orange and green.
It is normal for the phone to produce more heat when put under stress.
ie: games

Ghost touches

Anyone else getting the ghost touch problem?
I couldn't work out what was causing this on my phone so I enabled show touches in the development menu and it shows.
It goes from 2 to 3 spots on the left hand side of the screen.
It's not a major problem but happens at least 3 times a day and won't snap out of it unless I put the phone back into sleep a couple of times.
Do you think maybe scratches on the screen cause this?
TIA

Is your phone connected to a charger when this occurs? It might be it, since im experiencing the same thing since htc desire hd.

No. Can happen at anytime. Quite random.
It takes a few on and offs with the sleep button to stop it.
Can't get off the lock screen until it goes away because I can't move the unlock slider.
Very annoying.

I had the same problem - the first day i got my hox. With and without the charger (with charger a litte bit more often i think).
I pushed the complete left side of the screen (top) carefully and now it works well. No more ghost touches ^^.

Ok. Once I pushed around the screen edges, the left side has some play and moves maybe a mm with a slight creak.
I push it in but still that little bit of play on the left side.
It's quite impossible to show the service centre the problem because its so random but now I can show them this.
Cheers.

I hope you'll get a new "perfect" hox and i'll not have the same problem later :fingers-crossed:

[SOLVED] Black Screen Issue

Hi. I am not sure this is the BSOD problem that others have had.
I bought a second hand i747. It came with 4.3. It will work fine for a few minutes when first turned on, then the screen will go dark. The menu and back buttons stay lit, and the touchscreen still works, the LCD just cuts off.
If I hit the power button, it sleeps the phone. When I hit again, the screen will come on, but only for about 5 seconds, then it's black again. Everything works, just black screen.
Is it possible for it to overheat or something? It doesn't feel hot at all, but if I turn it off and leave it for awhile, it will again work for about 2-3 minutes, then only about 5 seconds at a time again.
I swapped batteries, and it's the same. The battery had pink on it. I opened it up, and none of the other stickers showed water exposure, and the board itself was clean.
It has stock 4.3, and is not rooted.
I did go to phone settings and turned off the "darken screen during calls" checkbox.
I am wondering if the proximity sensor heats up and shuts the screen off. Grasping at straws I suppose.
Any idea of how to fix this?
Thanks

Perhaps a bad capacitor in the digitizer/lcd assembly? My TV had an issue with a bad capacitor that would cause the screen to blank out after a few minutes???

I'll try swapping boards in it later, and maybe at least narrow down if it's the board or the screen assembly. I have an extra proximity sensor I could swap, but it doesn't seem like it's that to me.
thanks, will post more after the board swap

Update: I switched boards (different carriers), and I could not replicate the problem in either phone. I had hoped that would show that either the board or the LCD assembly was bad, but I didn't learn anything useful either way.
I put the boards back in their respective bodies. It still happens now, but not as often. It also appears to be totally random. I did switch batteries in the problem phone, and it doesn't seem as bad. I will try another battery switch and see if that helps it more.
When the screen goes dark, the menu and back buttons are lit. When it went out last night, I could see that there was still some faint background light that I can't see in the day. I pulled up Youtube and did a video, and when the screen went dark, I could still see movement, but couldn't make anything out. So, the phone is still going in the background.
If I push the power button, it sleeps, then push it again, and it wakes up just fine. Sometimes I have to do that 4 or 5 times for the screen to stay on. Sometimes it goes dark after 10 minutes of use, sometimes a half hour, sometimes just a few.
Any help is appreciated.

Well, right before throwing the phone into the wall, I noticed a partially removed liquid exposure indicator. I pulled the phone apart to check the motherboard.
In the process of taking it apart, I forgot to take out the SD card. In so doing, it pulled the sim/sd card module off the motherboard. Low and behold, there was a very light corrosive glaze in a few spots under the module.
So, I got out the 99% IPA, and a toothbrush, and cleaned the whole entire board. Since then, it seems to be working fine.
I don't know exactly what part getting cleaned fixed it, because I just cleaned the whole board.
Anyways, maybe that'll help someone with inexplicable issues downstream.

Thanks for following up with how you fixed the problem. In retrospect, water damage makes sense.
I dropped a Captivate into an ice chest full of melted water last year. I immediately pulled it out and the phone was mostly okay for a while but then the microphone didn't seem to work so well and occasionally the right third of the screen wouldn't respond to touch until I cycled the screen on and off. The water damage sticker and phone interior showed no signs of water.
I will probably sell the old captivate but with full diclosure about the history. Would have been nice if the seller had done the same for you.

Thanks, I should have thought of it sooner, but it didn't seem to have any signs of water damage otherwise.
I ordered the 99% IPA online, because I couldn't find any locally. It works wonders with previously wet boards. You might be able to bring it back.
