The heap check mode on a Samsung phone is a debugging tool that the manufacturer uses to check coding errors in the phone's operating system. The heap check mode appears when the phone experiences a problem writing to its internal memory or memory card. The error message most commonly appears when you take a picture with the camera. The errors shows up on the screen, and the phone stops responding. To fix the heap check error, all you need to do is reboot the phone.
Turn off the power on your Samsung phone. Some phones have a dedicated power button; others require you to press and hold the "END" key.
Wait a few seconds to make sure the phone is completely off. If the phone will not turn off, remove the battery. Check the phone's manual for battery removal instructions.
Reinstall the battery if you had to remove it; then, turn the phone back on.
Tips & Warnings
- If the error persists even after rebooting the phone, contact your cellular carrier's technical support department.
