[marovacka]

hello everybody
I have a problem with internal storage of my GSmartMaya m1 v2, android 4.2.1. You can see the screenshot attached to this message (.png). I can't understand what problem it is, because as you can see in picture (.png) there are different values of free memory in text and graphical format. Do anybody know fix this problem? Has anybody some suggestion?
thanks for your advices
