Any idea?

Happens to me as well. No idea why either.

It happened to me when I connected my Defy to the Apple's Greenpoint charger.
So I think maybe there're some problems with your USB port or your data cable.

With some SBFs i dont't have this Problem!
This is magical

I had this problem when I started using the phone. After wiping it vanished.

it happens to me with some chargers but not with others. With original and with other LG no problem, but with another i have that problem too.

I have this issue too with samsung charger. I guess this is feature

I guess the problem from the usb cable it self because i have this problem before when i connect the phone with the original usb, the touch screen works properly but when i used cheap chinees cable then the touch screen become crazy

use advanced task manager it its probably helping in such matters , just end all and restart if any launcher u have already.

What is the color of the LED when you plug it in? Also, if it is an R800i (GSM) version, you could try unlocking the bootloader and reflashing the device with Flashtool. Check out the development forums for tutorials on both bootloader unlocking as well as flashing.

gsm version, how can i flash it when it wont come on or boot and the computer not recognizing the usb device connected. the led flashes red

If it only blinks, it seems that the battery was too low.
plug in your charger, after 1 hours charging try it again.

I remember reading a thread about blinking red light. Not sure what it was now though.

you will need to have it repaired then. seems like a hardware problem if u ask me.

just letting u all know i fixed it was the battery. it was totally dry. used a universal battery charger which if very cheap and brought it back to life, now i think i wants to flash ass any sim card i put in it i get no signal its unlocked too

my xperia play wont hold charge

My xperia play can boot and does turn on but only if it is charging e.g. usb - pc or a wall charger...
But the moment it is removed from charging it reboots into a bootloop... But only if it is removed, and when charging and the phone has booted up I cannot touch the screen to get a response at all I have to use the game pad buttons to navigate I have a locked bootloader I am not rooted and it is running the latest stock firmware, model:r800i

Have you tried putting in another battery? If the problem is the battery you can buy a new one...

i dont own another battery but i dont think that it will solve it because the touch screen wont work either

Perhaps you can try to restore it using SEUS or PC Companion.

[Q] PC Shuts down when connecting HOX via USB cable

Anyone know why my PC shuts down whenever I connect my HOX to it using USB Cable? Actually it also happens when connecting my gf's XE. Grounded or something? After it shuts down, it takes time to restar. Well maybe because it wasn't properly shutdown. Any help would be appreciated much. TIA.

Have you tried connecting your mobile with another pc/laptop, I don't think it was an issue related with mobile.
Anyway try installing HTC Sync which will install all the required usb drivers, which may help.

USB problem

Hello, I have problem with USB connection.
When the phone is connected to the computer, the phone starts charging but the notification of the choice of file transfer, charging, etc. does not pop up. The computer pops up message that the device is not working properly.
In fastboot mode, the same message pops up and you can hear the repeated sound of the connected device until the phone is restarted.
The headphones on the adapter and OTG do not work either.
I tried different cables so it's probably not that, I also replaced the bottom board with a USB port but also no effects.
Could this be due to damage on the motherboard? How could I change rom without usb? I have uploaded MIUI alpha 8.5.31

You can try edl mode and if that doesn't work too that maybe a hardware problem

Hey. I read about such problems on one of the Polish forums, and from what I know helped to clear the usb socket on the phone. Maybe it's stupid and will not help but it's worth trying

I have exactly the same problem.
I think if I do a hard reset, maybe the phone reinstall the drivers knowing the new usb board.
Have you solved it?
