What is root access and why do you need it?

Root access (from English root —“root”) is superuser rights in the Android operating system. They are locked by default because they give full control over system files. With root access you can:

• ⚡ Overclock the processor and video card to improve performance (overclocking).
• 📱 Install custom firmware (for example, LineageOS or Pixel Experience).
• 🔄 Make full system backups, including application data.
• 🔍 Recover deleted files, even if the recycle bin is empty.

• ⚠️ The phone becomes vulnerable to viruses and hacker attacks.

• 💥 One wrong step can turn your phone into a “brick” (inoperative device).

   su

   If an input prompt appears (# instead of $), root access is active.
