 On first boot, the phone may remain on the Samsung Galaxy A71 logo for several minutes, this is normal and only happens on first boot, however in some rare cases, the phone will hang. If the phone doesn't go past the Galaxy A71 logo after 15 minutes, hold down power+volume down to reboot the phone, afterwards it will boot.
