Fixing Samsung Galaxy Z Fold 4 not turning on problem
One of the issues that you might experience with your new Samsung Galaxy Z Fold 4 is when you are unable to turn it on. This can be a frustrating issue coming from a premium smartphone. What happens in this case is that the Android device might not turn on when pressing the power button or it might just simply randomly turn off and not turn back on anymore.
Here’s what you need to do to fix this power issue you are experiencing on Samsung phones.
Solution 1: Check for signs of physical or water damage
The first thing you have to do with your Samsung Galaxy Z Fold 4 when it does not turn on is to check for any signs of damage to the device.
You might have dropped your phone causing it to have a cracked display or some internal component might have been damaged due to the drop.
Another factor to consider is water damage. Although this is an IPX8 rated device this only means that you can use the phone even when caught in the rain. This doesn’t mean that the device is water proof as there’s still a chance that water might get in and damage its internal components.
You can verify if your Galaxy Z Flip 4 has suffered from water damaged by checking its Liquid Detection Indicator located inside the SIM tray slot and is visible when the tray is removed. When the device has contact with liquid the X marks become pink or red.
In case the issue is caused by physical or water damage then you should contact Samsung and have this phone repaired.
Solution 2: Soft reset your Samsung Galaxy Z Fold 4
Sometimes the problem can be caused by a minor software glitch which is why you should try to do a soft reset. This refreshes your phone’s operating system and will fix any issues caused by a firmware crash or software glitch.
