Has your phone suddenly started doing its own thing—opening apps, typing random letters, or scrolling like it’s haunted? If so, you’re likely dealing with dotyk ducha, tiež známy ako screen auto-touching alebo phantom tapping.

- Open the dialer.
- Enter one of these codes (varies by brand):
*#*#3646633#*#*(MediaTek devices)*#0*#(Samsung devices)
- Navigate to Touchscreen alebo Hardware Testing.
For iOS Devices
Apple is more restrictive, but you can:
- Use third-party apps like “Phone Doctor Plus” for basic diagnostics.
- Access settings for some touchscreen-related testing via Settings > Accessibility.
Calibrating the Touchscreen Using Engineer Mode
Once inside:
- Tap the Touchscreen test.
- Follow the on-screen steps to test and recalibrate.
- Save and reboot your device.
