This is a good idea. I've had to learn how to disassemble and fix phones for the wife mostly and me leastly. She broke a camera glass - and a glass coated back plate. My issues were battery replacement and a USB port replacement and one headphone jack replacement. All things I managed to learn how to fix to keep our 5 to 7 year old phones going until we were damned ready to get a new one. Durability is crap for a reason.
