Hello again and thank you all for your advices . Let’s go:
The battery is perfectly flat and in good condition.
A couple of months ago I disassembled, cleaned all the contacts and reassembled the phone.
Since I have this problem, about a month ago, I have disassembled and reassembled the screen once again, tightening the screws (brand new) especially in the screen contacts area. I will do it again as soon as I can. What could I do to fix a “pogo pin” if there is one that is not movable?
I will try this, thanks.
Yes, I learned this the hard way
No, I don’t know anyone, and I can see that @angels_vigo can’t help me either.
I have to admit that it would make me feel a bit uncomfortable to ask for help from someone who is not a bit of a tech person, as I have the suspicion that several of the problems I have with my FP3 have been due to the modularity and with taking it apart (even though I’ve only opened it when I’ve needed to: to tighten modules or clean them… maybe about five or six different times). So I’m afraid that I might “mismatch” their phones, or something like that.
In any case, that’s just my thoughts. It’s actually a very good advice. Thank you!
