Hello! I have had my tablet for about a year now and suddenly, it stops charging. At first, it stopped charging and I had to plug it in a really specific way in order for it to work, and then bam. No charge at all. I've tried EVERYTHING, literally EVERYTHING to try and fix this. Multiple chargers, holding down volume up and power. I've looked all over the internet, and nobody seems to be able to fix my problem. Help!!
