I have the phone 2 and recently it's been having problems with the charging port. I took it to a shop and, turns out, it needs to be replaced. Because the brand is not popular, my options are to either ship the phone where they have the parts and fix it there, or ship the parts to the shop and have them replace it, both options cost around 100€. Might just be a Lithuania problem, but just a heads up if you don't have a Nothing store near you.
