[Q] DHD screen turns on with no reason

Hello all,
Since this morning I have a problem with my DHD. When I turn off the screen, it is supposed to stay of until I turn it on again. Since this morning it starts turning itself on over and over again. Everytime I turn off the screen, it switches on in a few seconds. But once it's on it doesn't go off by itself. So I doubt if it is a problem with the on/off switch. What else could it be?
Edit:
This seems not to happen when the phone is connected with an USB cable. Either on my PC or on the regular power charger.

Have you installed anything new at all. Also have you restarted the phone since it began exhibiting this behaviour. Make sure it's a proper restart aswell by turning off fastboot i settings, it's under power settings I believe.

Thanks for your fast reply.
I have not installed anything new since two days ago. And the problem really started this morning. So I guess it is not caused by a program I installed a couple of days ago.
I have indeed restarted my phone. Also turned it off, toke the battery out and waited a couple of minutes (just to make sure it was really really really turned off) but this did not solve the problem.
The thing I find very weird is that it does not happen when the phone is attached to USB...

Maybe USB debugging, or possibly a short on the mini USB connector. What firmware do you have on the phone?

Android 2.3.3
HTC Sense 2.1
I also think it might have something to do with a short in the micro USB connector. Have cleaned when the phone was of. Seems to have solved the problem, but that's only for the past few minutes...

Darn! The problem still isn't gone. It appears to be less frequent than an hour ago, but the screen still turns on every couple of minutes

This is happening to me as well. The phone screen keeps coming on and then going off after a bit. This and randomly going into car mode and whenever I make or receive calls, the phone speaker is switched on automatically.

Indeed! I just noticed that too. I received a call and my speaker was turned on without me turning it on manual..
Update: my phone stopped switching its screen on automatically, but the problem with the speaker still is not gone.

My DHD has started showing both of these symptoms, ie, switching itself on from standby and the speaker phone being activated on incoming calls .. ever since I upgraded to Android 2.3. I'm not sure if this is something to do with 2.3, the DHD or T-Mobile (my provider) .. or a combination of all 3.
And an app called Car Panel keeps launching ..

I have this problem, too.
Before the last update of my DHD the backlight turns on in standby for some milliseconds. I saw only a short flash in standby.
After my update to version 2.3 this happens everey 7 minutes.
And the backlight is on for about 10 seconds, then turns off for the next 7 minutes.

DHD light off on
I had the same problem going to settings/dock and turning off auto launch and then power setting turning off fast boot appears to work so far

[Q] Xperia Arc rebooting randomly for no reason? :(

Hi all,
I recently bought a Xperia Arc, all new, as i started using it noticed it reboots itself often, for no reason apparently, its very annoying since it takes about 2 minutes to restart.
It doesn't matter if i'm taking photos, video, playing games, or even in a call, it can reboot anytime, the screen freezes for like 2 secs then shuts off and restarts.
I cant take it to SE cuz i bought it overseas, and since it's my first android i have no idea what's wrong with it.
It's a wonderful phone and don't wanna have to sell it because of that.
Any ideas on what could be happening? and how to fix it?
Thx in advance.

Install both (required for the drivers):
- PC Companion: http://www.sonyericsson.com/cws/support/softwaredownloads/detailed/pccompanion/xperiaarc?cc=gb&lc=en
- Update Service: http://www.sonyericsson.com/cws/sup.../detailed/updateservice/xperiaarc?cc=gb&lc=en
Use any of them to update/repair the phone back to stock.
Or use the FlashTool and flash it again.

If it continues rebooting after reflashing it, then you need to take it back and get an exchange.

Thanks BluechipJ and daveybaby, im currently at work, so i'll try reflashing it tonight.

I found if the device gets hot (Upper portion of the back, not the battery. I guess that's where the CPU and RAM are), it reboots. It happens more often when I play games while charging. while standing by on battery, mine never reboots by itself. If your problem persists, maybe you need to consider replacing it.

My Xperia Neo used to crash randomly too, usually once a day or once every to days. For some strange reason, it seems to have stopped since I've started using AppKiller and Go Launcher. Right now I'm in the 125th hour of uptime and counting...

yea mine restarts quite often when people call me...im going to take into docomo today and let them know...

been testing it for several days now, the reboots stopped after the flashing
Thanks again

I have flashtool,do I just re run it? will i lose my root/apps/data?

Mine freezes sometimes and then the screem goes of from left to right and reboots
Did you have the same?
Sometimes it runs for 100+ hours and today it happend after 39-46 hours uptime.
It mostly happens when I use it a lot and the RAM was quite low before. Maybe mine runs out of RAM?

Um... could be? Im using a task process killer now so maybe. Try autokilling unnecesary processes.
Cheers

Mhm, everyone says they do more bad than good.
But I'll look at processes that eat up RAM when it runs for a while. Currently it's fast @ ~ 30 hours uptime.

Have you tried to take the battery out and wait for at least 10 sec before putting it back in?
Another option is to "tease" the RAM and take out the battery while the phone is on. This should of coarse be a last resort.

Phone randomely stops booting. Not even into fastboot (black screen)

Hey. So just yesterday I flashed Venom's kernel (could be completely unrelated to the issue). However today my phone froze up and when I tried to reboot it all it does is vibrate. The screens stays off completely and all it does it vibrate once every minute or so. I tried the guide to unbrick it and restoring it with xFSTK but it's basically impossible since it keeps rebooting and it is only detected for a couple of seconds before it disconnects again. I managed to get it to install dnx,fwr droidboot and ifwi. But when xFSTK tries to start it up nothing happens and it times out. Hopefully someone can help me here. Never seen anything like this before

I think I saw somewhere a similar thread. Their solution was to let the battery completely drain before starting it back up. Maybe it will help?

I tried opening up the phone and remove the battery. Then left it detached for a while, then reattached it. Since making it run out of battery could take days. I will still try that however. But detaching it and reattaching it did nothing unfortunately. Went right back to vibrating every minute or so with just a black screen

Random and untimely reboots

Hello everyon everyone.
I have the SM-P600 version, everything was good until the beginning of the week when touchpad began to go off without reason, and completely random.
I first reinstalled several official ROMs from the most recent to the oldest, with no significant improvement
Then i rooted and tried Lineage, it looked good for a while, but in the end same problem.
Please note, when the tablet begins to mess, the reboots are occuring more and more often and after a while it turns in a loop and im not even able to switch it off.
Samsung logo display, black screen, logo, black screen, etc ...
I think rather for a battery-side problem, if some people have faced similar problem, I'm taking help.
Do you know if by chance we can use the tablet without battery to test this theory?
Thank you in advance for any answers.

I think I'd be taking a close look at the physical power button. Seems to me that if it had gone flakey it could cause something like this.

Hello and thanks for you answer,
Just to precise i never faced this issue while flashing an official or custom ROM, dont know if it is just luck or it can help in anything
Anyway ill try to check it the power button just in case

It's weird I just started having this exact problem myself. One morning I unplugged it and it had shut itself down overnight. Since then it randomly reboots. Sometimes I can get 20/30 minutes out of it, but once it starts, it can get into multiple reboots with the only way to stop it is to plug in the charger. I tried wiping cashe/dalvic (no help). Nothing was recently changed (including apps). Tried resoldering battery connector (battery was replaced a year or so ago with OEM Sammy). The P600 is rooted with TWRP installed, but no custom ROM. Usually the reboots start while I'm doing something (surfing, email, etc.), but I don't think it will do it while sleeping. I'm considering the power button, but I don't see this exact problem anywhere else, but this post. Any ideas?

OK. My tablet has taken a turn for the worse. Now it is stuck in a continuous boot loop. I tried the power switch, no help. I tried booting into TWRP, and it went back into rebooting before I could do anything. Strange thing is I can put it into download mode indefinitely without it rebooting. Should I ODIN back to stock? I tried the resoldering of the battery connection earlier. Any other ideas?
