my phone was working fine but then when I went to use it again it felt really hot so I took it out of the case & turned it completely off so it would cool down. I waited an hour but Now it won't let me turn it back on. I've held down the power button for seveal seconds and it didn't work. I've also just pushed the power button once and released and it won't work. Any suggestions? thanks.
Check the battery if you can see any abnormalities like if it is bloated or not. If it looks normal, try charging it if it reacts.
