Reset the Samsung s8, I turn it on comes up Samsung screen.. then goes to installing applications then turns back off. How long does it take to complete this? Or how do i sort this out? I have never experienced this before
Is the software on your phone up to date? Go to Apps > Settings > About device > Software update. Also, let's try a soft reset on the phone. This will end all processes and give the phone a fresh start. To do this, press and hold the 'Power' and 'Volume Down' buttons until the phone restarts.
Let us know how you get on.
