However, over time, owners often face the need to transfer accumulated photos, videos or documents to the big screen for saving or editing.
The process of connecting a smartphone to a PC may seem elementary, but in practice, users often find that the computer simply charges the gadget, ignoring the files. This is due to the specifics of the MIUI shell and the security settings of Android. In this article, we will discuss all possible ways to connect the Xiaomi Redmi 4A to a computer, and solve typical driver problems.
First of all, you will need a proper USB-A cable, preferably original or certified, capable of transmitting data, not just current. Many cheap out-of-the-box cables of other devices are designed solely for charging and don't have the appropriate contacts inside. 4A The computer cannot see it, start checking with a cable replacement.

Once you have selected the correct mode, a new removable disk will appear on Windows (or other OS), and you can now copy files, and it is important to understand that the speed of copying depends on the USB standard (2.0 or 3.0) and the quality of the cable itself.
Configure USB modes in the developer menu
In some cases, the standard notification menu may not be displayed or not work properly, so you need to force the connection mode through the hidden developer menu, which is especially true if you plan to use USB debugging often or work with ADB.
