Things I noticed today when I did a OTA update (MF3) on my ATT S4. I've been using the ES File Explorer app to tether. Before the update it would seem to completely bypass any verifying. After the update, a pop verifying pop-up now appears and blocks it. I discovered that if you DON'T press the ok button on the pop-up, you can still tether. Although sometimes you might need to remain on the same screen(shown in pic). But for the most part, I've been able to press the home key and still be connected. Tried it out the last time for about 30min to make sure it's stable. I also noticed after the update is the WatchOn app always shows up on the statusbar and remote in notification screen. Even when I go into the WatchOn settings and disable it, after another reboot it will show up again after about a minute. Might need to install a startup manager app to stop this. Anyways, doesn't really bother me since I rarely reboot my phone. As for rooting, the same motochopper method doesn't work. You'll have to use THIS method. It's just as quick and easy, but if you have your SD card formatted to anything other than exFAT, it will probably be a slight pain to back up, change format, and restore. Or you can use another card if you got.
