Another small update,
Went to the store where i bought this phone, and played around with the other Lumia 830's on display. only to find that they 2 have this behavior.
That brings me back to an earlier conclusion that maybe that shipment has those problems, or the dutch ROM. I really cant tell.
Or otherwise all those Lumia 830 owners have eye's that cannot register any flaw's with they're particular phone ;-)
Me and my girlfriend have the Lumia 830, from the same store! Her's has the exact same problem, i convinced her to switch from android to WP because of the lack of lag, fluidnes etc.. and we have to deal with CONSTANT lagging.
It's not (as i already said) a major lag or the phone doesn't hang at all, its micro stutter always present, on the home screen, in the app list, in all app's, even the WCentral app (and on the 820 i never saw this micro-lag-stutter).
I cannot get this phone to scroll smoothly true anything, not facebook, not internet explorer, not anything! This cannot be a coincidence or just those phone's. my guess is that the euphoria from the new phone hasn't settled down yet and i hope more people will come to they're senses and complain about this.
I cannot get over the bull**** advertisement line for this phone (affordable flagship) it's not affordable in the first place, its a 400€ phone lol, and its certainly not a flagship!
The other thing that worries me is that other people with Lumia phone's have issues and they never got addressed, in stead i read how many people are going back from a better Lumia to an earlier model or lower spec'd model to get away from the quirky bug's and hardware issues.
Microsoft get your **** together please, i love this platform and i always defended it. But this is getting harder every year, the gap is widening and it needs to be fixed!
I will try to make a video in the coming weeks to show what i am experiencing.
