@userUV5wQ2KHeR not sure what you are planning on purchasing but I haven't seen the S7 on any list as a possible device.
Not sure about the damage to the Note 9. You may want to sell it outright instead of trading it in.
S7 is on the list of eligible devices for a trade up offer for s21 with bonus $450 trade vakue towards new phone. So is note 9. Thats why im trying to trade up and why Id rather trade than sell.
