hi, my back of the phone scratches after a while and i'm looking for a new one (not a case or a cover, just a back plate). i got a black iphone but i'm sick of all that fingerprints so i think to try the white one. a. is it complicated to disassemble? should i disconnect the pcb/screen and staff to disconnect the original backplate? b. what tools i need to use to make it easier? c. i didn't find original backplate, anyone try the alternative from china? it's feel and look like the original or much cheaper? btw, if its not the right forum please move it for me, i didn't knew where to ask that. many many thanks.
