Updated Android last night. This morning phone will not turn on and says:
Your device is corrupt. It can't be trusted and may not work properly. Visit this link on another device: g.co/ABH.
O2 chat is offline so I can't speak to a technician, and I can't ring them as my phone won't turn on.
Please note, this is not customer services and we cannot access your account. Do not publish personal details (email, phone number, bank account).
Link to our guide on how to contact them can be found here
