My Desire Z doesn't vibrate anymore! - G2 and Desire Z Q&A, Help & Troubleshooting

Not even when booting ( that short vibration before it turns on the screen ) nothing. NOTHING. It came all out of a sudden, a few minutes ago it worked.
Any ideas? Android Revolution currently.

If it really happens even on the HTC boot logo, I'd guess for a hardware failure. Is your guarantee time still on?

I don't think so. Oddly, it started working again. Very very very faintly at first, and gradually getting stronger. It seems that it's normal now, but I kinda feel it will do it again.

Suddenly my mt3gs starts to vibrate and reboot

This problem it's becoming more and more frequent - it was once a month, then once a week - now almost daily
The mt3gs starts to vibrate very fast for 5 seconds, black screen with no interaction possibility, and then reboots.
Ever happened to anyone?
I'm running CM 7.2

Cant say Ive had the exact same issue, but have had similar. Could be a number of things. Some ROMs have problems with phones rebooting when WiFi is turned on. Not sure about CM7 though. I would recommend making a nandroid backup, and reflash your ROM. If it stops happening, it is likely an app or something corrupted causing it. If it continues, go back to a stock ROM and see how it acts. If it stops now, then it was probably something wrong with the ROM. If it continues, it may be a hardware problem that cant really be fixed. (try a different SD card too.)
Yes, sometimes when i turn on wifi, the phone reboots, but it is a different behaviour - the "wifi reboot" it's a system crash, so the screen suddenly turns in the mt3gs boot logo.
When this happen, it is starts to vibrate a lot (for example, it happened at 4am, it woke me up, even if it was far from my ear), then "dies" for a few seconds (doesn't respond to any button press), and then reboots
very strange...

Screen bricked ?

Greetings, Interwebs !
2 days ago I sat in a subway and had my Xperia Play R800i Unlocked Bootloader w/ TrueAncestor in my pocket. Till then it worked perfectly fine. Some time later I took it out to check the time and looked at a screen filled with random pixels of different colors. I took out the battery, put it back in and booted. As soon as the kernel`s bootlogo would normally show up, I got the same distorted screen. But the phone boots. It vibrates and the LED flashes as usual. Note that I didn`t change anything software wise before it bricked.
So when I got home I took out the battery again and went to sleep. The next day I put it back in and got the distortion where the kernel logo should have been again. But then it showed the ROMS` bootlogo and booted normally. The only thing strange was that the screen would flicker and have random glitches on everything thats rendered by the CPU. Every game worked just fine. But the random glitches also would vary in strenght and quantity. Eventually I would get none for about half an hour.
So today I flashed AOKP and again, I can`t even see the bootlogo.
Am I right in the assumption that some hardware is broken ?

[Q] Phone stuck in screensaver mode

Hi!
I brought my Xperia Play phone USED two years ago and I've never had any problems with it.
However, recently, the phone has started to freeze itself in "screensaver" mode (Where the screen goes black after 15 seconds and locks the phone), but the screen won't light up no matter which button I press. I've had to restart the phone every time this happens.
It's been behaving strange at start up as well, as it sometimes take 20 minutes just for it to turn on, while on other occasions, it won't turn on at all!
Is this problem caused by the battery, or is it the hardware?
Is it with stock firmware?

Yes.
I've never modded it or installed custom firmware/apps.
Have you tried factory resetting it?

Yes, but it didn't fix it. The problem still occurs.
tldr: Black screen, no display, everything works "under" (I can answer the phone etc). Not a flex cable problem because occurs randomly, regardless of the slider being open or closed. The problem also occurs during boot up, so rather not a software problem.
I think I have something similiar. Everything was fine until a few days ago the screen didn't want to unlock..or at least I thought it was that.
Basically the phone sometimes works OK but sometimes if I turn off (lock) the screen, it won't go back. To be precise, the phone works and if someone calls me I can pick it up moving the finger where the slider should be, it's just the display doesn't turn on. Same goes for booting, bootloader logo etc, so IMO it's not a software problem.
Strange thing is that it just randomly pops back, sometimes when I move the gamepad slider, sometimes when I put in a jack cable or if I hard reset the phone (remove battery). I've had problems with the flex cable in the past and this time I know that it's not it (no difference if I open/close the slider).
My guess would be some power supply or LCD driver IC issues, because the screen stops working almost everytime if I put the phone into the dock. Moreover, if the screen doesn't work, the orange charging LED is not working (green and blue are OK). The moment the screen starts working, the orange charging LED starts working too.
it's very strange but I'm used to electronics doing strange stuff. Just wondering if I should give a try disassembling the phone and trying to fix it or just buy a new one or something?
I might add that I have bought a new battery ~3 months ago, but it's been working fine to this point. I have tried if the same problem occurs with the old/original battery and it's the same.
well, any ideas?
edit: This video shows something very similiar (except the backlight): https://www.youtube.com/watch?v=m4p0-kv1cxA
Same problem. And I guess this guy has it too.

LG G3 unresponsive/extremely slow

Hello there. I have to write this again becuase the last topic I wrote didnt get posted...
I have a big problem with my G3 and I have tried everything I could but nothing helped so I hope you can help me.
First of all my phone is only stock. I didnt try rooting it or installing custom roms on it.
Heres the whole story of what happened:
A week ago my phone started to act strangely. When I tried turning the wifi off it restarted or froze for a bit and then went on normaly as if nothing happened. I didnt even have to input my pin. Then one day I got home and the phone simply started reseting itself constantly. Always loaded up to the pin screen but I didnt even have time to input the pin and it reset it self again. This went on for like 15 reset before I lost patience and pulled the battery which didnt help at all since after being turned back on it went back to the reseting. I found online that it was probably a battery problem but I was impatient (shipping to my country is over 2 weeks and buying a battery in stores here costs twice the normal price of a genuine battery but only for a "fake" battery) so I factory reseted it via power button+volume down. After that it worked normally but I lost all my data.
The day after this I spilled ice tea on the phone. I opened it, cleaned it and let it dry out. Turned it on after an hour of drying and it worked but after maybe 2 hours it began freezing. When I tapped on the screen it didnt react, when I pressed the power button it took more then 10 seconds to react to it. It turned on, didnt react to touch and then in mere seconds it went dark and then turned off. I couldnt even unlock the screen. Tried pulling the battery but then it wouldnt even turn on. It stayed on the LG logo. I left it on the logo and on the charger and after an hour or so it turned on and worked normally so I took it apart and cleaned it once more even under the screws and such and it worked after that. Until today.
The freezing problem returned. I was playing a game on it and chatting via messenger when the phone stopped reacting. I had signal, wifi, I got new notifications and basically everything on it worked but the screen didnt react to touch and when pressing the power button it took over 10 seconds to light up the screen, then it went darker and then it shut down. Couldnt do anything. After I pulled the battery it would get stuck in a boot loop for maybe 10-15 minutes and then load but the phone couldnt be used. Just as before the screen turned on with a delay but no reaction to touch whatsoever.
I tried factory reset, downgrading to a lower android version (from 6 to 4) with LGUP and lg flash tool, and I bought a new battery. Nothing worked. I managed to get it to android 4 but that didnt help either. I though it was a problem with 6 because the problem started after the update, before that I didnt have a single problem with my phone.
Now its in a state where it doesnt work. The phone is running, apps are upgrading after the factory reset and all that but I cant do anything with it. Once in a while it will work normally as if nothing but that is rare.
Could you please help ? I love this phone and I dont want to have to sell it for spare parts.
EDIT: I left the phone running to see what would happen an after several hours an error message appeared saying "Process system isnt responding". After pressing ok it worked fine. How can I fix this. I googled it but all I found was a problem with sd card (none is inside), with battery (I have a new one) and with rooting (mines not rooted).

D855 completely unresponsive, tried countless ROMs, now stuck in a boot loop.

Hi, so a week ago I had this weird problem with my phone. It would just freeze for like 2 minutes, work again for a minute and so on.
Did a hard reset, same problem.
Flashed that 6.0 KDZ, no success. The phone started but I was basically stuck at the lock screen, touchscreen was unresponsive, power menu kept showing up for no reason... couldn't even turn the phone off.
After that, I decided to stop ****ing around with it and send it to a repair store (no warranty). Today, after about 5 days, I picked it up and was told that they tried a ton of ROMs but they have no idea what's wrong with it.
Got home, ran a hard reset again and now I can't even get to the lock screen, phone is basically in a boot loop. LG logo shows up, the "Android is starting... Optimising apps" screen does its thing, restarts and keeps going like this forever.
Is there anything I can do or should I just throw the phone in the garbage and get another one? Any suggestion is appreciated, thanks!
Hi,
Same issue for 2 days...
My G3 was suddently slow and unresponsive so I removed the battery.
I put it back again, as usual, and start the phone. But it get stuck at the LG logo.
Sometimes the animated LG logo shows up, sometimes not.
Sometimes it displays the PIN screen (unresponsive or not), sometimes not.
Sometimes it boots totaly normaly (1% of time) and become unresponsive/buggy after a couple of minutes.
I tried flashing kdz (normal and CSE) 10 times, factory reset, change battery, without success...
Good luck.
