Replacement Back Battery Door Adhesive for Samsung Galaxy S21 Ultra 5G SM-G998U G998U1 G998 - Pre-Cut Double Sided Glue Tape Sticker - 2 Pack

M6 samsung s21 ultra overheated while playing a game. This caused the sealant to fail resulting in a loose backglass. After cleaning the residual off, this installed easily. I compressed the phone over night and found it perfectly adhered. I highly recommend it.

Excelente producto

It works but sizing is slightly off and adhesive quality feels low.

Gets the job done.

Fit for Samsung Galaxy S21 Ultra. Stuck well to the back cover of the phone. Use it more then two month, no complains

S21 Ultra has a 2 piece back, the lens cover and then the rest, which is curved and has no defined edges. They want you to stick it to the back first then remove the tiniest tab of backing, which rips in half leaving you to try to un-fdo the sticky on the lens part without screwing the whole thing up. no durability. no adhesion. no value for money. no functionality. no quality. Id "return" it if it was worth the gas to get down the street.

Did a screen replacement on an s21 ultra, this made sure the plasitc back of the phone would reattach just fine

Buen producto

Le quedo muy bien, después de cambiar la pantalla de mi celular, adheri la tapa trasera con esta cinta doblecara o como sea y la deje toda la noche con las ligas puestas, pero como que no se pego muy bien tanto en la tapa como en la carcasa, en fin mantiene estas 2 en su lugar

vendor didn't let glue set, hope this holds. Seems to have worked, having a spare is handy

Does not bond phone well. It separates shortly after. Disappointing
