Volume buttons won't work, camera button wont work, and speakerphonew button wont work. Happened out of nowhere. Cannot lower/raise volume on side of phone, only vibrate works.


Hello.
Welcome to Fixya's Community.
These problems HAve been related to a damaged flex cable.

This is the cable which in the U700 connect the lower part of the phone to the lcd part (with the screen, speaker, camera and touchscreen buttons). All the data such as screen images, camera pictures, speaker sounds pass through this cable from the main board which is located in the lower part of the phone.

Unfortunately, each time one opens the phone, the cable slides between the two part of the phone. In the long term, as the cable is thin and soft and this movement causes frictions between the cable and the parts, the cable consumes itself. the damage of the cable could results in weird effects on the phone.


In order to fix that you need to replace that part.
its easy.
just take the phone apart and locate the flex cable and replace it.
believe me you can do it yourself.
  • The Flex cable of your phone cost 3 $
  • A phone repair shop will fix that for 25 $

see if you can find it on eBay.
remember its SCH-U700 Not SGH-U700 there is a big difference.

Good Luck

My htc touch pro freezes and sometimes wont let me text.


Well u can start with reseting the phone from the little red button next to the charger piece. If that doesnt work, go to your company store and they should give you a brandnew one and transfer all you contact, cal ecents, ect. They can transfer everything except ur txts and emails. I hope it all workds out.

White screen on samsung sch-r450 messenger frm water damage


the only possible thing you could do yourself is to remove the screws, pull it apart and try to blow dry. That's the only thing you can personally do.
