Every time I try to make or receive a call my phone hangs up.

Hi acaraballo my name is Mike Houston a Social Media Representative at DISH and I am happy to help you today. I do see you have preformed a Hard Reset (unplugging it for 10 seconds), would you press the Menu button and select the numbers; 6-1-1 and select Check Switch and then Test. After all test complete, exit out of all menus and allow the receiver to reacquire the signal and download the program guide. If you have nay further questions please e-mail me at [email protected] and I will assist you further.

The phone has hung up because there are errors in the software. So to reset remove the battery and the memory card from the phone. Using your PC , scan the memory card for any corrupt files or media files with virus- it is possible when they are downloaded from unsafe sites. If so remove or format the card. Now replace the card and battery and switch on the phone. If the phone hangs up then it is confirmed that the software is corrupt and will need a reinstallation.

try to format with the following link

Try these codes:

*#3370# - Enhanced Full Rate Code (EFR) activation. Increase signal strength, better signal reception. It also help if u want to use GPRS and the service is not responding or too slow. Phone battery will drain faster though.

*#3370* - (EFR) deactivation. Phone will automatically restart. Increase battery life by 30% because phone receives less signal from network.

Its still under warranty, i guess
Send it to the company for service

you go to msgs seeting and change ur msga xenter nomber as ur sim msgs center number

the phone needs to be reflash take the phone to a mobile service center and have the firmware reflash.

Master Reset

take the phone and have it service then if that does not help the issue take it to a mobile service center and have them reflash the keypad with the flash file.

hi there, your camera is faulty and needs to be replaced or it could be a problem with the phone. I suspect the camera once everything else is working o.k. You need 2 take your phone to the nearest service technician to get it replaced. Replacing the camera is fairly easy from my experience as a repair tech. Sam !
