I made an application in ionic 2 and everything works perfectly, however, a user when using on the mobile with android 4.4.2, some functionality, such as file upload, does not work.
It does not generate errors, it simply does not upload.
In addition to the initial loading time, before the splash, it takes almost 1 minute to load.
Does anyone have any idea if it is some ionic mismatch with this version of android?
