If you accidentally left your phone in the car and it overheated and won’t start here are a few things you can do to get a quick fix.
If you can remove the battery, check to see if it’s deformed. If it is distorted replace the battery.
For inbuilt battery phones, press the power button and the volume(-) button at the same time for ten to fifteen seconds and let the phone will restart. If it reboots and starts acting funny give Fixit Mobile a call at (844) 651-9277 for a free estimate.
