How do you get out of recovery mode without computer?

To exit recovery mode without a computer, you can try performing a force restart on your device. For most iphones, quickly press and release the Volume Up button, then the Volume Down button, and then press and hold the Side button until the Apple logo appears. For Android devices, the process may vary, but typically involves holding the Power button until the device restarts. If these methods don't work, you may need to wait for the battery to drain completely and then recharge it.
