Pure Junk and seller will not respond. Seller will just take your money and Amazon helps him.
It is pure Junk and the seller will not respond. The seller will just take your money and Amazon helps him do that. The battery will come charged at 30% and will not recharge. The battery is junk. DO not buy. Go to eBay and buy the original battery for 15 dollars.

Damaged my S20 phone
Thank you Amazon for selling me a new $500 phone because the battery your company sold me heated up during charging and destroyed my screen. Great gimmick -- sell batteries that damage products that your company can then sell back to your customer.
