Mr. Fixit.....

most recent: I have a company issued $1200 Samsun S21 ULTRA phone. Its in an otter box so it can take a fall. I dropped it once it 3 months but it was a deusy. 10 foot onto a wooden plank floor of a foot bridge. It landed flat on its back, face up but with no physical damage evident but since then it's cellular service sucked. No reception unless your under a tower. And even when it showed bars, there was no internet. So I put in a request for a replacement phone and it's on its way. For kicks I looked up the construction of this phone and found that the cellular antenna is on a daughterboard that is socketed to the motherboard from (you guessed it) the backside of the motherboard. So like pulling a dent, I applied some force opposite what caused the damage, ie I smacked it face DOWN onto the concrete floor a few times and voila, it's working like a champ again! That shock action must have seated the daughterboard back onto the motherboard. I put the phone face down on top of a piece of 2x4 and slammed the 2x4s bottom onto the ground so I would apply the force to the phone equally and not on the corner or anything that would break the glass. Fn A. It worked! Now I may have an extra phone laying around......
