Xiaomi smartphones based on MIUI firmware, by default, have such a cool function as a flash when making a call. Yes, many users do not need it, but if there is a need for this function, there is no need to download and install third-party applications. Is not that great?
We are looking for the item “System Applications”.
Select the application “Phone”.
Next – Incoming Calls.
Turn on the item “Flash on call”.
Or turn off depending on the need.
After switching on, check the flash’s operation: ask someone to call you. If the flash worked on a call, then you did everything right.
