My first DIY phone fix made me a self-repair believer

My first DIY smartphone repair project was off to an inauspicious start.

I’d successfully removed the back of the HMD Skyline, but the next instruction called for a T3 screwdriver bit. I had a T4 bit, which worked well enough to turn the screw that popped the corner of the phone’s back panel up. But a T4 was just too big for the tiny screws holding the battery connector cover in place.
