So today 17/01/2022 

My s21+ went black after disconnecting a call

I tried the power volume down nothing happened then I tried charging nothing happ

Then I waited half hour and left it in its box as EE will collect it 

However 5:45pm my phone turned on🤣 so random but shall I just let it be

Hi,
You should let EE have a look at it while it's on warranty.

Well they said if it turned on then they cancelled the courier pick up

They said if it happens again then call us to rebook for repair collection

The same problem happened to my cell phone has it happened again since the last time because mine just turned on 5 days later.
