This is so strange and I'm really not sure 100% how to explain but I cannot turn my WiFi signal button on to be able to connect to any WiFi or hotspots at all, it goes like a misty blue colour as if when just turning on, then stays like it for a while and goes back off, it will not search or pick up even recently connected WiFi. I had it sent off and got it fixed but warranty has run out and also do not have insurance, iv done all necessary steps that has to be tried )factory reset updated as it should be and still nothing) has anyone else experienced this sort of thing? My mobile company had never seen it before so couldn't assist me with any help, tia s21fe
