it looks you are an Apac based SE , will contact you to discuss this as am working on something similar in Techsupport
If it's working for a few days and then it stops, it doesn't look like a configuration problem (or at least not initially). Can you capture device logs through ADB and attach them here? There will probably be information of interest there that can help troubleshoot this.
Does the problem persist after a reboot?

yes it persist after a normal reboot. We need to do an enterprise reset or factory reset everytime.
I have the same problem with MC33.
The scanner works but don't transfer the barcade data to boxes, only beep this.
Home button doesn't work
And all another issues you describe here.
In my case, some configurations of the android system are lost too. Screen orientation fix in portrait come back to auto rotate, the inactivity screen timeout, configured in 30 minutes come back to default 1 minute and the timezone juat come back to default too.
Everything come back to work with a factory reset, but in some days the problem returns.
The issue was resolved after a patch on Nougat OS given by tech support.
