I'm having the same problem with my phone, i thought the Instagram glitch was a poorly developed feature of the app or something.
But the most annoying problem is when I plug in my phone to charge. By default I expect the screen to light up and show that's it charging. Instead with my phone it switches off and this isn't the normal way you see the Nokia logo or something when it shuts down. It out-rightly goes off. Like someone pulled out the power cable to the tv and it takes 20 or so minutes before it boots up again.
Overall the UI is amazing together with the experience. But please do find a fix for these bugs.
From UK with Nokia 3 phone still stuck on Beta Oreo, anyone else?
