It’s been a while since I had the phone, but iirc it would drop wifi constantly, Bluetooth would occasionally and randomly cause the phone to seize up and you had to do a hard reset, you could only have a Bluetooth device connected to it alone, if the device was also connected to something else no audio would play from either device (I think that had a work arojnd in dev option, but i dont recall what it was), the screen would go unresponsive if you had youtube playing in background mode, and a handful of other things.
Most of them were worth it just for the Hold For Me feature, though. Lol. God I miss that.
