[Verizon Samsung Galaxy S7 Edge Questions & Answers] snake2332:
Tasker is definitely handy for me, or really vital if I want my carputer to function properly. My car has a Nexus 7 in the dash and, in order for my phone (S6 and S7E both) to enable hotspot automatically when it connects to my car stereo, it HAS to have root. Pretty dumb, but as of Android 5.0 (I think) no 3rd party apps can enable the hotspot on Samsung devices. I tried pretty much every "hotspot" app. As soon as you have root, Tasker is able to enable hotspot.

If anyone cares about my carputer setup: I get in my WRX and start it -> power inverter stashed under drivers seat is plugged into 12V power/cig lighter and remains switched off but still sends power to its 4 USB ports when car turns on (remains quiet since its fan is noisy when switched on) -> N7 has the fastboot mod that makes it boot up when it senses a charge -> meanwhile, phone with root + Tasker auto connects to car stereo via bluetooth, phone Tasker turns on hotspot once it sense BT connection -> N7 connects to hotspot and launches CarHome Ultra + a volume control app that increases volume with GPS-sensed speed (like modern car stereos do, like volume speed compensation in my Fusion).

When car turns off, N7 has Tasker set up so it goes into airplane mode when no charge is detected. This way, I don't have to wait for it to boot up if I, say, go into the store real quick. Then I have a task that shuts down the N7 at 7pm since it's usually parked in my driveway/garage after 6pm.

I also have a laptop under the passenger seat since WRX ECU-flashing requires Windows-based applications. I leave it under the seat and when needed, flip switch on power inverter -> laptop has BIOS setting to turn on when AC current is detected -> laptop connects to S6/S7E hotspot -> I use TeamViewer to connect to laptop from N7 tablet -> pull out Logitech keyboard w/touchpad and use it instead of N7 onscreen keyboard -> hack away at WRX tuning/modding stuff.

Pretty fun stuff, in my opinion. In my previous WRX, I had a 7" Liliput touchscreen on top of my dash, 800x480 resolution but had it displaying 720p, connected to Windows laptop running WRX software (RomRAIDER?) that basically gave me 20 gauges on-screen (half of which I didn't know or care what they displayed, haha, but air-to-fuel ratio was there and motor-heads would spend $350+ on physical air-to-fuel ratio gauges), and Garmin GPS software with a USB-connected GPS antenna, etc. I love cheap carputer setups. I never wanted to go all-out like the real carputer guys do. Laptops are easy to setup and I tend to get free ones from work, making it very cheap for me.

So having root on my S7 means I don't have to pack around my S6 with me for carputer needs. I leave the S6 work phone at home and just have call forwarding set up so the calls make it to my personal phone. As soon as the S6 is paid off, I'll probably get rid of that phone line and give out my personal # for work purposes. That'll save me some money on my Verizon bill, which is kind of a ridiculously high $254/mo for 4 smartphones for 3 people, one of which is an 8 year old girl with a Note 4 (I know, I'm a terrible parent. She also has my iPad4 that I gave up on after trying to deal with iOS for a few months).

Once again, sorry for the rambling, somewhat useless information in my post, hehe.
