Hi
I have a Samsung S4 and the wifi just stopped working randomly. When I try to turn it on it gets stuck on a light green shade for awhile and then goes grey. In the settings it just says 'turning on' but it never turns on.
I have tried restarting the phone, taking the battery out - all the basic easy stuff that I have found from googling and watching youtube videos. The *#0011# thing. And done a factory reset. The phone isn't damaged so I don't think it would be a hardware issue.
I've read a bit about flashing and rooting the phone but I don't know much about it - and worried I might end up downloading something with malware or something!
I don't really want to take it in to Samsung service centre either because its not under warranty.
My Samsung S4 is running on android version 4.2.2
Any help/suggestions would be appreciated.
Thanks
