That’s why: You should always turn off your smartphone before cleaningdisconnect all cables and only switch the device on again after it has dried. It is best to use a slightly damp cloth and avoid aggressive cleaners – they can attack display coatings.
Scenario 8: If you become a victim of a fraud attempt
Do you receive a text message from your “bank” or a message from supposedly “Microsoft Support”? This is often an attempt at fraud, often accompanied by malware. Do not click on links or follow scammers’ instructions. If you accidentally do it, then it is better to turn off the smartphone immediately to stop possible background activities such as active downloads, data theft or hidden scripts.
In the next step, you should not start the device again until you can check it in safe mode or use a security app for analysis. Here you can read what you can do if you have caught a virus on your cell phone.
Scenario 9: When the display develops a life of its own (ghost touches)
Does your smartphone suddenly open apps by itself or react to entries that you didn’t even make? Behind these so-called Ghost Touches There is usually a software error or a defect in the display (digitizer). This can trigger uncontrolled actions – from accidental calls to incorrect PIN entries – and, in the worst case, permanently lock the device.
In such cases, you should immediately turn off the smartphone completely to stop unwanted entries. After restarting, check if the problem still occurs. If it persists, it makes sense to repair it, replace the display or purchase a new smartphone.
Scenario 10: Before and after important updates

System updates bring new functions and close security gaps – but can also cause problems if something goes wrong. If your smartphone is already running unstable, hangs up or shows error messages, you should switch it off completely and restart it before an update.
This ensures a clean operating state and can avoid update errors. Even after an update, switching it off completely can help if the device reacts unusually, apps crash or the battery suddenly drains quickly.
Conclusion: Switching off can save lives – that of your smartphone
Whether it’s heat, cold, software errors or a security risk: turning off your smartphone is more than just an emergency solution. It is often the quickest way to limit damage or prevent problems from occurring in the first place.
Particularly in sensitive situations – such as possible attacks, unstable system states or when traveling – consciously shutting down can make a crucial difference. At the same time, restarting at the right time (e.g. before an update) prevents some errors from the outset.
