Major HTC 10 Oreo Update Issues. Help Needed.

[BUB5]

Hey all,

Just updated to Oreo and I'm having immense issues currently. (Sprint)

• Volume buttons not working
• Back button & Pages button not working
• Fixed notifications that cant be removed "Voicemail is running" & "2 apps are running in the background"

I've never had an issue with the major updates, so I'm not sure how this one completely messed up my phone. Any help is greatly appreciated.

Thank you.
