| Risk | Explanation | |-------|-------------| | | Many one-click root APKs contain trojans, adware, or data stealers (e.g.,假冒 KingoRoot variants). | | No Unroot Option | Without a computer, reversing the root may be impossible if the app doesn’t provide an unroot feature. | | OTA Updates Broken | Over-the-air system updates will fail on rooted devices, and without a PC, restoring stock firmware is difficult. | | Warranty Void | Even on older devices, rooting may permanently trigger Knox or other e-fuses. | | Brick Risk | A failed exploit can cause boot loops.
