Some people have had this problem. Seems like the fix is to shut down the phone remove the battery and clean the contacts on the battery and phone side. Recommend a business card or and eraser. Don't use chemicals.
I personally haven't had any problems, other than a reboot if I drop it. Which has happened like 5 times in a 1.5 years
Yes, this is not unique to Q10.
Occurs on my Z30 randomly and infrequently.
OS version is irrelevant, occurred on carrier production, unofficial.
BBVE passes all tests.
Historically, this occurred on 7290's, found to be a carrier related issue.
More recently one carrier had an issue resolved that caused 9900's to do the same.
It is still happening to me. Went weeks without any issues, now within last week has happened 3 times. Also getting double typing randomly. Never had double typing until recently (about 18 months).
