As the title says, I only have the motherboard & battery from my galaxy s3 and need all the other parts. Should i buy them all separately or would it be cheaper to buy a new s3 and do a board swap?

@nickolair it would be a lot cheaper and easier if you buy a used replacement and then just transplant your motherboard. At least that way you know that you will have all the parts you’ll need with one purchase. Use this guide Samsung Galaxy S III Motherboard Replacement for the repair
