I believe Stylo 2 is an LG device. I don't think it has that feature, but if it does it will be an option in Settings/Security/Screen Lock or Settings/Lock Screen/.
Should be in language and input, but it may be in the settings of the keyboard app. I believe with Gboard it is in the Gboard settings, but could be different depending on the keyboard app.
Take a blow dryer to to the usb port...maybe just needs dried. I've had similar issues with the headphone jack before, so hopefully it will work again once it's dry.
I would try a different usb cable and/or power block. USB ports often get damaged, so this could be the issue. Most of the time I see this it is just not the right amperage on the charger output.
I recently bought a Moto G4 Play...same thing. No stock music player, browser, file manager, e-mail, etc. Also, the system apps it does have like Camera...are on the playstore being updated. Weird.
It seems they don't want AOSP apps anymore.
Did you delete GMSCore.apk? That is google play services, which will cause Gapps not to work. If so, you would have to try and download a copy from your browser and install it to system with root or backdoor install it with unknown sources enabled.
Enable dev options by going to Settings/About Phone/ and tap on the build number 8 times.

Interesting...sounds like an issue with package manager and ART runtime. It's not doing its runtime conversion at installation, but it does on boot. There seems to be all sort of bugs with the new runtime environment, though I haven't seen this one before. Commonly, people have issues with...
Download the firmware from www.sammobile.com/firmwares/ as well as ODIN and Samsung Universal USB Drivers.
Boot into download mode with vol-, home,(if it has it) and power. Press vol+. Connect to PC and open Odin. You should see a blue block with a com number and it will say ...Added in the...
Might try removing the battery if you can. If you can't remove the battery try holding power and vol+ for 8 seconds or so to see if it will reboot. What model is this?
If you use Odin to flash TWRP (if it is available for the device) adb will work by default in TWRP. My suggestion is try to get into download mode and flash TWRP, then once you boot TWRP you can grab a copy of minimal adb and fastboot. Unzip it to a folder then press shift and right click...
