Hi, I just bought a Pipo U1pro for my childrens but after the very first charge the screens seems to flicker all the time, as long the battery goes down the screen brightness fades to black, at almost impossible to use! I charge and discharge the tablet, try hardware reset, firm update and nothing seems to work!. As I am in Uruguay in the other side of the globe in reference with the seller and so I have no option to returned it, I appreciate yours opinions of the problem It could be a battery or screen problem? because I´m evaluating buying a Samsung T1000 battery and try to change the original one. Thanks for yours answers!
