Well like I said the last time, I will post when I bought the new phone.
In the end I decided not to go for a Poco X3 Pro cause the more research I did the more concerned I became and also posted on a ~local review/bench forum of that specific model and even there an owner atually suggested me to stay away if I want to feel 'safer' with my purchase.
Apparently there is an issue going around that some owners experience ghost touch after a few months of use where the phone's screen just wont react to anything randomly till the side power button is pressed.
Since I need a phone for 3+ years this is not something I felt risking, in case I also end up with a model like that.
'and knowing my luck I would'
That and also the size+weight of the phone turned me off.
Instead I went with this:
Realme 8 6/128 4G Punk Black variant.
Sure its by no means a power house but its still a significant step up from my Snapdragon 625 3+ years old phone.
Bought it for ~226$/191 Euro, locally bought in my country and has 1 year warranty on it.
It was fairly free of unnecessary apps and even those I could delete and the Realme UI feels kinda user friendly imo.
Still got to tweak a thing or two but I like it so far and at least its barely bigger than my old phone and ~same weight so thats a good extra.
There was a transparent-ish case in the box for it which I do
'took off for the pics' use cause this shiny plastic back collects fingerprints like hell.
