Wow! You’re absolutely right about the Nespi Case. What a crap of case! I didn’t know any thing about this issue.
In all test that I did using Nespi case showed lightning bolt randomly Without case everything fine and never showed lightning bolt.
About Nespi Case, I’m Not sure about crappy wires... maybe the buttons or the micro usb connector is loosing power. Who knows... where’s the faulty component. As it is randomly, it makes me thing that sometimes something it isn’t doing contact well.
Again, many thanks. I’m going to try a SuperPi Case, and we’ll see if it works better.
