I purchased an Onn. Tablet in Sept 2020 at Walmart. Now it will not charge. I have changed cables and purchased new cables and it still will not charge. Sometimes the battery will show "charging" for a couple of minutes but the battery % goes down, then the charging indicator stops. I've had this table for less than a year. I do not get cell service at my house so please respond via email. kiminwis@***.com
