In looking into getting some old phones off ebay and practising on them. Is there any one who can offer me any advice, maybe which sorts of phones to look out for?I'm from the UK if that makes a difference. Was going for battery and screen replacement initially as that seems like a good place to start. Many thanks all

I'm starting screen and battery replacement and was searching for some battery adhesive I thought it might be universal strips but I'm coming across module specific ones. Is there not a roll or a universal type one I can cut if necessary??
