So, here is my problem: One time, I am setting an alarm, but I noticed that my phone doesn't have a stocked Clock app. I also go to
/system/app/ClockPackage_ESS.apk using ES File Explorer. I installed that .apk, but when I'm trying to install it, it says "File not installed."
Here is the screenshot (click to enlarge) of the App Drawer:
Also, here's the device information:
Device Information: Samsung Galaxy Core Prime Model number: SM-G360HU Android version: 4.4.4 (Kitkat) Baseband version: G360HUXXU0ANL6 Kernel version: 3.10.17-388893 dpi@SWDD6214 #2 Thu Feb 5 16:44:31 KST 2015 Build number: KTU84P.G360HUXXU0AOB1
Does someone know how to fix this problem?
