Description

In my last version of app i update to SDK 12.2.1.GA.
So after upload it to production some ANRs start to appears in Crashlytics describing some slow IO problems with TiProperties.

I can't reproduce the problem and i don't know how it happens, because it happened in different screens of application.

For now it's only an Android problem (11, 12 and 13 versions).

The main log:
