Can I change the digitizer of the android tablet? If not what's the other option if the screen turns black?
Well Canon Herrera, It is possible to change the digitizer of the screen of your android tablet or for that matter any other tablet PC. First you need to find the exact make of your tablet PC and then search of its digitizer online. You can get good deals on eBay for that too. Changing the digitizer will require some skill.
If you can tell me the exact make of your tablet PC, i can post step by step procedure of the digitizer changing process. Else you need to take your system to a hardware expert who will open it up and see the actual fault in the system. If it really is the digitizer, then it is good as it is not very costly.
Other thing could be if the issue is in the motherboard, then it will be a lot of money to spend for you. Do take it to an expert if you are not comfortable opening it.
