[mgrabarski]

Hi, I also have this problem. Someone find solution for that?

[dmsherazi]

I noticed that this occurs on emulator only so I ignored it... haven't faced similar issue on a real device

[dlazaro66]

As @dmsherazi notice, this only occurs in an emulator. This is fixed, but not released yet. Will be available in the next version.
