My phone went from 32% to 100% with green light in 1 minute and temperature reached 67°C (never seen this before). Very hot to touch and had to remove my back cover as it could've melt. Shutted off my phone very quickly and removed charging before it blows up. I am feeling in danger with this phone, what if it blow up when i am using it. I turned it on again after it went back to its normal temperature and now its showing 29%. What's going on?
