options to hide navigation bar and status bar seem to have disappeared on android 4.2 (using a french android 4.2 Samsung Galaxy Mega phone with opera mini 7+ ( I tried opera mini 7 and opera mini 7.5))
these options are here using opera mini 7.5 on an english android 2.3 Samsung Galaxy S2 phone with opera mini 7.5
I see in http://my.opera.com/community/forums/topic.dml?id=1533402&t=1386408054&page=2#comment13628912
that some people were able to use old versions of opera mini ( 5.1.22460 ) to get the original full screen behaviour back on some Android 4.1 phones (Samsung Galaxy Note 2).
Unfortunately Opera Mini 5.1.22460 doesn't seem to work on my android 4.2 Samsung Galaxy Mega (only versions >= 7 seem to work)
Has anybody succeeded in getting full screen opera mini on android 4.2 ??
Thanks for any feedback !
