Meizu M8 SE something wrong with No Service

hi

I just receive my M8 SE but there is a problem when i call someone, i can talk for 2 mn and then its shut the call, i have the no service and the search ...
After he can detect my operator.
It happen to me 3 time!
What i notice is when is shut down in the call menu there is appear ' application data' in the case miss call .

Do you know what is it the problem?

here the picture:

Firmware version? Seen someone posted such screenshots at the chinese BBS too. It's probably fixed in the latest official firmware.

The firmware is 0.9.3.8 .

Is it a bug from this firmware?

could you power off the phone, take out the battery, check sim card and put all back, then start the phone again. see if the phone back to normal.

cuz, this happened to me,
my battery was drained out very quickly, about 2, 3 hours from 99% to 5%. the screen was somewhere between hot and warm. the phone kept searching provider. that scared me. i just took the simcard out and inserted it again, then all became to normal again.

After upgrad to 0.9.3.9 i try call my friend its wroking fine but let see tommorow.

strange
my m8se had it the other way around!
had such a bug on 0939, downgrade to 0938 : it worked fine.

Hey Guyz what Happen to M8 SE??
Why it still have the problem !
After upgrade to the last firmware, it still have the same problem, iam in call and only 1 mn after it cut the call, i have the no service and then appear my carrier!

What is the problem?? any solution!!!???
