Just because the Samsung Galaxy Note 8 and Note 9 was working fine and then it suddenly started to keep restarting, it shouldn’t worry you too much. It always starts like that, when you expect less, after a period when it was obviously working just fine. Do we need to say that you are not alone in this?
On one hand, you have us, ready to show you what to do and how to try to fix the Note 8 and Note 9 that keeps restarting, on your own. On the other hand, you have all the other Samsung users who have been through the same experience as you or who are even dealing with it right now.
As a rule, it appears that the device restarts and displays the Samsung logo on the screen, while doing so. It can restart at relatively equal time frames or in similar situations, like when using a particular app. But it is also possible to restart, several times in a row, completely without warning. We’re not just talking about your Samsung Galaxy Note 8 or Note 9. We also talk about the Galaxy S6 or Galaxy S5, the Galaxy S4, the Galaxy Note 5 or Galaxy Note 4 and so on. Many Galaxy models can act like that at some point.
Do you still have your Note 8 or Note 9 covered by warranty? If you do, save yourself the time, the money, and the stress of fixing it on your own. Ask the seller to take care of it and wait patiently for an answer. Now, if you’re not that lucky, take some extra time and think of what could have possibly made your smartphone reboot, freeze or shut off so suddenly. Did you, by any chance, install a new app recently? Perhaps a firmware update?
With the last two questions, we’ve summed up the two main situations and solutions for a Samsung Galaxy Note 8 or Note 9 that keeps restarting:
#1 – Bad firmware update, requires factory rese
When you have just installed a firmware update and problems like the ones mentioned above start to manifest, you must factory reset the Samsung Galaxy Note 8. Pack up and back up all your data – or, in any case, all the data that you don’t want to lose – and follow the instructions from our tutorial mentioned above. The device will return to its factory defaults, you’ll be able to bring back your archived data, and the restarts and the freezing should stop.
#2 – Faulty app installed, requires uninstall in Safe Mode
The Safe Mode is a safe environment where only the default apps installed on your Samsung Galaxy Note 8 from the factory will work. Everything else that you have added afterward, including that faulty app that is now making your Samsung Galaxy Note 8 or Note 9 restart, turn off, crush or freeze, will be blocked. Of course, the simple fact that it doesn’t work in Safe Mode shows that you cannot do something in particular about it. But you can test if that’s the problem by monitoring to see if the phone stops restarting when in this mode.
If that’s the case, you need to uninstall that app. To get there, however, you’ll have to completely turn off the phone. Then, press and hold the Power button until the screen activates and shows you the Samsung logo. Then, hold the Volume Down key and press it until you’re asked about the sim-pin. From that point, the Safe Mode label will show at the bottom left area of the screen and you can start your investigations.
