Touching the man button do not bring me back to home screen

Did upgrade to flyme
Works OK except of the above mentioned problem.
Any idea how to fix it?
Thank you for your help.


Retry installing the firmware with clear data, however I suspect it might be a hardware issue.

Hello Ray,
Thank you for your comments.
I don’t want to reinstall the upgrade version with clearing data. What you mean by “hardware issue”? Is it fixable?

Well, found out how it is work post upgrading: short upward sliding move from the main virtual button, instead of just touching it.

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
