BTW, by disabling some of the security options (hardened memory allocator and enable compatibilitymode )
There is not a single crash but several in a row.
I never got any notification on this Phone.. (apparently notify_push does not cooperate with TALK, and the phone has no access to Google whatever... (No playstore et.al. installed).
