The worst I've done is thinking I was sliding a mod in my pocket, instead I dropped it on concrete, busting the mod. For some reason I did this twice in the garage. I've learned to actually feel for the bottom of the pocket when put the mod away.
I have however had an epic phone contamination once. It was during the pandemic, I was in a public restroom. Had my wife's phone in a bag. Leaned over and the phone fell out, bounced off the nasty public toilet and slid under an adjacent urinal.
Took the case apart, washed it with soap and water. Then followed up with antibacterial wipes. I've never cleaned something with so many antibacterial wipes in my life. And that was back when someone would mug you in broad daylight for a pack of them.
The whole time there was this maskless guy wheezing next to me in this small bathroom. I thought this was going to be how I got COVID.
Never told my wife about it. I feel like some things you shouldn't tell your wife, it's better for a happy marriage.
