i saw this bug now on samsung galaxy 5 ( android 5)
LG G3-S ( android 5.0.2)

so now i cant use the inappbrowser at all.
the steps i did to install the new inappbrowser are :
1.ionic start myApp tabs
2. cordova platform add android
3.cordova plugin add cordova-plugin-inappbrowser

thats it.
and the inappbrowser looks funny
if any 1 can help
