iPhone won't turn on properly after charging
When I got home and my phone was dead, I put it on charge and then it started to come back on as the apple symbol showed up like usual, but then instead of turning on it just stayed like that for ages. Now it just keeps showing the apple symbol like it's about to turn on but then it just goes away, comes back again, and does it all over. It's been like this for hours now.
(also, its nothing wrong with the charger because I've tried many different chargers)
