how to turn my android back on

It's only because it's completely flat that it seems not be charging. Just leave it on charge all day and night and it will eventually start to charge up again.

Best not to let it run completely flat in future.
 


if your battery is removable, i am sure that you will find the +ve and -ve points of the battery. this experiment is practically successfull. you hav to find a 12v dc power source and make sure its ampere rating is not more than 850 maH. then make a rapid contact on the +ve and -ve terminals with the respestive terminals of the power source. you have to only make a contact of not more than 1 sec and make sure that tha battery is not heated.is this not works, increase the duration of contact, say 2,3 4 sec. this will definately work.......
