OK, so what is your experience after updating to Pie?
I have a dual SIM unlocked version, received the update like 2 weeks ago (3.31.401.1) and am frustrated with it - Oreo worked much smoother.
Issues identified:
1. Reboots - usually when I lose Wi-Fi connection.
If I am connected to Wi-Fi and lose the connection (e.g. leave the building, go the the garage) - the phone reboots when the connection to Wi-Fi is lost (it's not a full boot - more of a soft restart or sth), but causes me to loose Bluetooth headphones connection and I need to enter the PIN to unlock the device after that (fingerprint unlock does not work after restart without providing the PIN).
Super frustrating, happens multiple times a day.
2. Notifications coming back and back.
If I receive a notification from some apps (e.g. Instagram, OneDrive) and dismiss them, they reapper some time later (same notification that I dismissed). Sometimes multiple times, example:
a) Notification pops up - I dismiss it.
A minute later.
Same notification. I dismiss again.
5 minutes later.
Same notification, AGAIN.
I start to miss the good old Oreo. HTC proves once again they no longer care about updates for their older phones.
