I have an iocean X8 mini pro (MTK6592 android 4.4.2) and I flashed a ported MIUI ROM yesterday.
The problem;e is that the icons of the calendar, clock and weather are disappeared (still work if you tap on them) at the default theme. Those icons appear when using other themes.
I tried by clean launcher's and systems cache and data but did not help.
Please help if you know how to fix that.
