So, I just plugged my phone to charge it. It was 35% when I plugged it, then when I grabbed my phone to check on it, it won't light up or anything, the LED indicator was lit, it was red and I unplugged it, still the led indicator was red. so I tried the force restart, safe mode, the pressing of home, power and volume buttons but still no luck, what could be the problem? helppppp.
