phone emitted sparks while on charger
I am fairly new to iPhone repair my experience is limited to battery replacement and and back covers. The other day my phone had about an 80percent charge and I plugged it into an outlet. Shortly after it started emitting sparks and all the lights in the room dimmed. I unplugged it and opened it up. the battery appeared normal. I tried to replace the battery but as soon as I connected the new battery the phone began to get hot in the sims card area. What should I try next?
