There are certain applications in our phones that we do not want others to use. When one has kids at home who love using your phone, it is a safe practice to setup locks for applications as phone lock/unlock pin is not enough. App lock in MIUI 8 lets you unlock all or specific applications so that when the app is opened, you are prompted for unlock password. We have compiled a few guides for Xiaomi Redmi 4A.
