Does the last letter in the part number matter?
I ordered a charging port replacement for a S5 and the part model on the board itself says SM-G900W and I got a SM-G900T. I installed the part and the charging port works now but the microphone doesn’t during calls (except on speakerphone, which uses the secondary microphone). I am not sure what the issue may be as the only difference between the parts seems to be the last letter.
Any repair shops out there able to explain if the last letter on the part number matters or how do you determine which part is the right one.
