Stopped Working All Together

your little brother was mashing buttons and changed some settings. Restore the phone to factory settings.

may be your moterboard fault.

i got the same problem with my new UX32VD.
the camera worked properly for the first week but after that suddenly it's stop working.
any solution?

Mine would work fine until I turned on my wireless headphones...then the mouse would move a little stop.....move a little....then stop.

I made sure my headphones were on.

I turned off the mouse, moved the mouse reciver to a USB port on the front of my computer (the mouse reciver and the headphone receivers were next to each other on the back of the computer). I turned the mouse back on.

The computer imediately gave me the "installing USB driver" notification.

When it was complete....both played nicely together...no more problems.

The problem is caused by the emergency flasher unit. This is a common problem and you can find a few youtube demos on replacing it. I did it in about 30 mins. I don't remember the cost but it was stocked at my local chevy dealership.
good luck.

I had this problem about my touch screen same with you. The touch screen on left hand has stopped working. I had it for 20 months. I live in Thailand. I think that it is the big problem for ST550. I've brought it to Samsung Customer Center. and they've introduced me to change the new touch screen. It is about USD50.00. I am bored. I used it a little bit.

I'm guess they don't stock for they stop working in a few months.

I have three and after three months, they go on and off when they want to.

If it detects movement, they may or may not work.

Loved them until they went crazy.

There are many posts on the net about the problems with these. I'm probably going to ask
COSTCO for a refund. I suspect they've given plenty already.

It is doubtful that the battery is bad because they dont normally go bad suddenly. Usually, they will degrade slowly and hold a charge less and less before they stop working.
It sounds like you may have a loose connection somewhere. Check the leads from the circuit board to the moto and also the tabs that connect the battery to the circuit board. These sometimes break.
