My Z2 automatic reboot several times a day

[SL624]

Hello,

When I upgrade my Z2 to the latest revision of OS, it become so easy to automatic reboot.  It comes when I talk with customer.  that create a lot of trouble for me.   And it will have maybe 10 times per day.  

My software revision is 17.1.2.A.0.314.    Do you know what happen?  If I go back to latest revision, will it become ok?

Best Regards,

Steve Lou

Does the same occur if you remove the SIM?

Thanks!  After I move my SIM card to another phone, Z2 become normal now.

I think it should be SIM card contact issue, right? 

Thanks!
