By "rooting" an Android phone, we can overrule software limitations and become the true administrator of device.
Device manufacturers usually end the warranty agreement once you root your Android device.
Boot loops (constantly rebooting) are often seen in rooted devices because of faulty custom ROMs, interrupted software installations.
It is often seen to abruptly restart and freeze the device while performing even the simplest tasks.
By rooting, device's battery management features will be lost, means apps will be able to use all of the device's resources, which will drain the battery very quickly for no reason.
By rooting, we won't receive any security patches updates, which makes device vulnerable to malware attacks and hacking.
In rooted, custom ROM is installed, due to that, often see issues in IMEI information.
If device has IMEI issues, user will not be able to make phone calls or access the internet using mobile data.
