IPhone shows apple logo then quickly goes back to normal?

My iPhone will randomly kind of reboot in a weird way and show the starting apple logo real quick then go back to the lock screen.
I drop it a lot but I've never got it wet except for spilling soy sauce on it and that was like 4 months ago

Dropping it may be the culprit here…
Dropping a phone can be just as bad if not worse as getting your phone wet (very often a phone will still work when wet with water after its completely dry)

but before you go calling apple try restoring the phone.
If that doesn't help call apple, and they may be able to help you further.

  • My iPhone goes to the apple logo but won't turn on I dropped my iPhone just barely when it was out of battery. I plugged it in about an hour ago, but it's just staying on the appe logo and not turning on… It will go black and then come back on and it's done that a few times. What do I do! Do you think it's broken!
