Root

Rooting an Android phone gives full control over the system, but it removes safety walls, so malware gains the same power and banking apps may refuse.

Root: Root means full administrator control of an Android phone. Rooting unlocks the system so you can change anything, but it also removes the safety walls that keep apps apart. Any app granted root can read other apps' data and hide itself deeply.

Some enthusiasts root to remove built-in apps or to tweak the system. The price is high. A rooted phone often fails Google's checks, so banking, UPI and some streaming apps may refuse to work or may warn you. A malicious app that tricks you into granting root can then do almost anything without a trace. Apps that hide root from banking apps exist, but they make the phone harder to judge as safe.

Rooting tools downloaded from random sites are themselves a common source of malware. If you see root on a phone you did not root, treat it as a red flag, particularly on a second-hand or very cheap device. Safer ways to remove unwanted apps usually exist without taking this risk. Unrooting usually means reinstalling the official software, so ask a trusted service centre.

Tips

• Do not root a phone that you use for UPI, banking or work.
• Never download rooting tools from random websites or video links.
• Run the Safeavio phone scan, which flags a rooted device, and take care with a second-hand phone.
