How to access Styx Browser & Duckduckgo sessions/tabs on my Android & transferring them to my Linux PC, possibly adb method, is root needed?

@Hadron, Thanks for your response! 1.) I already explained why i cant just copy & email the URLs from my android to my PC.
2.) I will definitely learn from this experience & not allow it to happen again, but i am trying to transition & do just that, & need to save the current tabs/sessions i already have, so i can move on. This is my 1st time using android, so its a learning experience.

Screen Protectors?

My watches all have sapphire lenses, so in the absence of diamond tools the one thing I'm not worried about is scratching them ;).

"Gorilla glass", despite the marketing, is a different matter. The sort of quartz grit you find in everyday environments will scratch that just fine (I've scratched gorilla glass by just putting a phone face down on a conference room table).

How To Turn Off Location Tracking On Samsung Galaxy J2

You do have location settings. As said above, just search settings.

If you set location to "device only" that stops Google collecting "anonymous" (but easily de-anonymised) location information (though some apps, like Maps, will occasionally pop up a message that looks like it's telling you that you need to turn location on but actually re-enables the misnamed "high accuracy" mode that allows them to collect these data. The dishonesty of the wording of that pop-up and the way it bypasses the disclaimer about other consequences is for me enough reason never to enable "high accuracy" location, which anyway isn't more accurate as long as you have a satellite fix).

If you want to stop Google recording your location history you need to turn off app and web history in your Google settings as well as location history. Otherwise Google keep a record of where you used each app. There was a fuss a few years back about them keeping this "back door" way of recording location history, but Google won't have done anything about it.

If you don't use location at all you can just turn it off.

Dark mode on Android 7.1

Use dark wallpaper. See whether it has any theming options. See whether individual apps have a dark mode. That's it.

And don't get worked up about it: amoled phones existed for years before dark mode, I used one myself, it may use a little more power if you leave it on looking at the settings all of the time but it doesn't mean the phone is doomed.

What's the Camera Tuner system app?

So do I need to keep it on my apps ?
It's a Motorola utility to apply maintenance and performance patches to the camera module it uses in Moto phones, so I'd just leave it alone as is. It's a system-level app that's part of the firmware so you can't Uninstall it anyway. Besides, it's only a few kilobytes in size and only uses a minuscule amount of system resources even when it might be in use (which isn't very often), so there's no real benefit to trying to micromanage it.

How to prevent green line or display burn issue in my samsung note 20 ultra?

also do not let the display be on for very long and especially do not leave the screen on while displaying the a screen that does not change......in other words do not leave it on your home screen where your home screen shortcuts can burn into the display. my mom does this and on her s7 she kept her home screen on and it burned in Candy Crush into the screen.

so use a screen time out or use a live wallpaper that keeps the screen moving.

tct.gcs.wfcmanager stand for?

well tct is this:

gcs i think means google cloud service:

and wcs manager is " WFC Profile Manager connects to customer data services in the cloud, authenticates, automates, and enables multiple user role selection for dynamic line extensions or push-to-talk groups on a shared device."

.....in other words nothing nefarious going on. that is just your system process running on your device.
