My phone has been perfect till one day I turned off my wifi then turned it back on when I got home to find out that it won't turn on. The button will slide over to on but then slide back to off. It doesn't slide back and forth but it's like the phone doesn't want wifi to be active at all. I've done everything that I can find on the internet and still nothing. Booting in safe mode, wiping cache and even a master reset and still nothing.
