i have a dell tablet venue 8 .. android 4.4.4 . I had a problem that the tablet did not switch on the WIFI and the BlueTooth. When I try to switch them on .. the button gets stuck on the off then goes back to its place. I tried some suggestions that I got from the internet like shaking and tapping the tablet, power cycling and at the end , factory reset. After the factory reset I switched it on , chose the language and location then they asked me to choose a WIFI to connect to .. But there was a line written that i have to switch on the WIFI to connect .. but the problem is that I couldn't get to the WIFI to switch it on .. the upper banner couldn't be lowered down to connect to anything.
