I have version 2.7.3 as well, just to confirm.
Well, have you tried reinstalling the app/restarting your phone?
So the issue is that the app hangs after some usage?
Maybe you can explain your issue a bit more detailed? Is it the camera within Instagram that doesn't work?
What's the issue? This is not really related to OnePlus.
If you're referring to the new update, that's for iPhone as well.
Is it not working at all or just not responsive?
I would recommend contacting OnePlus support.
Or, you can use a VPN to Canada and get the update faster :)
Suggest a Bluetooth? what do you even mean? :)
Is it latency on everything you type or only sometimes?
Which game are you trying to play?
Which carrier do you have? maybe it's a temporary issue with your carrier?
I have only had problems with MMS, which a restart solved.
You can connect, check for updates but not download. Then disconnect from VPN and download & update as usual. Works for me.
Can you clarify what you mean?
My earphones are linked to one device only, until you unpair it. Perhaps that's the case?
Oh, I see :)
