I found myself using WiFi Hotspot (i.e. Wireless tether) more and more often as I got a tablet (Kindle HDX 7 inch) and it's WiFi only. I've hacked it so it runs both Amazon AND Google Play (thanks to XDA developers) but I need WiFi.
And for that, SlimKat failed to deliver. It's not their fault... Google changed KitKat's WiFi tether to make it more carrier friendly. I tried an Xposed module that supposedly fixes this, but I can't get it to work.
So it's back to Jelly Bean for me... at least for now.
