Many of us use a smartphone for communication and entertainment. However, modern Android devices have settings that require caution.
Factory reset. This function can improve the operation of the operating system, eliminate various errors, and update system programs. However, all data on the smartphone will be irretrievably deleted.
Developer mode and rooting. They allow you to access many functions on your smartphone. But if you set the wrong parameters, the phone may become unusable, and there is also a high risk of infecting the device with viruses. It's better not to enable developer mode or get root without a clear understanding of what it's for.
SIM card settings. If you set the wrong parameters, you may lose connection. Usually, these settings are automatically updated when you insert the SIM into your smartphone.
Other settings. It is better not to change the following settings: application permissions, date and time, special features. The latter are needed by people with disabilities.
