They're just gonna make shit up like they always do. They've already tried overinflating their "savings", I'm sure they'll just do it again. If the first lie doesn't work, go BIGGER!
GrqpheneOS has a second pin on your lock screen which, when keyed in, immediately makes the storage contents permanently inaccessible, deletes all Esims, and powers the device off. Graphene will remain installed.
There are also "panic button" apps out there that do similar stuff.
Then there's the good ole, put it in the microwave, or taking a nail-gun to it
Haha I did volunteer at a track for a bit and they paid me in rally car lessons, driving one of their WRXs through the woods, which was a blast.
They were convinced I'd done it before because before they taught me how, I was already good at left foot braking and could smoothly heel-toe while shifting, but in reality I hadn't driven an IRL stick shift for more than a few hours at most. That's not to say I didn't make some silly mistakes though lol
Bought an FR-S recently and once I get some new tires on it, I'm gonna see how I do on a not-dirt track!
Anyway I've switched to PC now, if anyone wants to race...
