Hello guys. I own a Lenovo Tab 2 A10 for less than a year. All of a sudden it stopped charging properly. Coincidentally, my sister's smartphone is having the same issue. We both use the stock Lenovo charger. At first I thought it was the charger's fault (duh). But, my sister's smartphone charges up to 100% (a lot slower than usual, but still). On the other hand, my tablet stops at 21-24%. It seems like it's charging, but it doesn't. I did order a new charger, but I just want your opinion. Thank you.
