Sero 8 takes hours to charge will not hold charge
Tab will charge for 2 hours and be at 10:% or it will charge and when I used it for like 5 min itwil go o zero how much would it cost to fix the battery and charging port
unless you have to move the charger around for it to say that it is charging, you will only have to replace the battery. The battery (at least for the Sero 7) is relatively complicated to replace. by that it needs to be soldered into place and likewise.
hope i could help
I would suggest saving time and money by buying a new tablet from a more reputable manufacturer. Hisense isn't getting any awards for helping customers with this problem
