• Nothing happens when I try to open an app from notifications. 
• Nothing happens when I try to share any thing from an app.
• Unable to import or export content from/in an app. 

To be very true these were the most annoying problem I faced after buying a Xiaomi Redmi 3S Prime. It was my first Mi phone so I was not very familiar to MIUI. I faced the issue when I tried to open some apps from notifications. Additionally I was unable to share and import content in some apps. After 10 days of trial and error, I got rid of the problem. Luckily it was not a big bug. This problem could upset you after buying a new phone so I am sharing the method to solve this annoying issue.

Step 1 

Step 2

Go to settings> Installed apps

Step 3 

Now select one of the apps having the issues. Scroll down to find and select "Other Permissions".

Step 4 

Turn on "Start in background" and "Display pop-up window" options.

Step 5 

Repeat the process for other such apps having problems.

Reason: 

Like other blogs and how-to sites I will not only tell you the method. I'll tell you what's the reason behind it. Actually in Android 6.0 Marshmallow and up apps get installed without asking much permissions. They later ask you to give permission to use storage, contacts, wifi etc. when needed. If you deny a required permission, app can't use a resource. In our case some apps don't ask to allow them to "start in background" and to "create pop-up window". When we give them permissions, they work fine.

What is android rooting?

Rooting is the process that allows an Android OS user to attain 'privileged access' or 'root access' on their android devices. Android OS is 'Linux' based operating system and rooting gives similar access to administrative permissions as on Linux and such operating systems.
We can root our Android devices to overcome system limitations set by device manufacturers, alter or replace system applications, run apps which requires root permissions, modify current firmware(rom), and install a new custom firmware or latest Android versions.

Rooting and jailbreaking

Rooting is often compared to jailbreaking Apple devices running iOS. These are quite different concepts. Jailbreaking is performed with a 'locked bootloader' to bypass several Apple prohibitions, to install external apps and modify system while rooting is performed with an 'unlocked bootloader' to get privileged access to install apps and modify system.

What changes rooting does on your system?

Though there are different methods of rooting for different devices, but usually they exploit firmware's one or more security bugs to skip the 'digital signature check' for updates. Then a modified firmware update can be installed which usually have utilities to run root apps. Such as the 'su binary' can be copied to the path /system/xbin and granted executable permissions by 'chmod' command. Now a third party root governing app like SuperSu or SuperUser can give root permissions to apps and keep their log data
