In this video, I'll be showing you a cool new app called "CTRL-F" that lets you search for keywords in real-world documents just like a web browser.
With this app installed, you can simply take a picture of any sign or document, then it will scan the image for every word it can find. Once that's done, you'll be able to search the document for any instances of a word, and you can even export the image as a searchable PDF.

In this video, Ill be showing you how to set up an app called DroidLock that automatically changes your PIN based on certain contexts like time, date, or battery percentage.
With this one installed, youll get an extra layer of security in the sense that, if someone ever looks over your shoulder and sees your PIN, the number they saw wont unlock your device the next time around. This isnt a lock screen replacement app, it just changes your PIN automatically. Even better, it doesnt require root or Xposed, and it will work on the majority of devices, so its a great setup.

Subscribe to Gadget Hacks: http://bit.ly/GadgetHacksSub
In this video, Ill be showing you how to move the clock back to the upper-right corner on your Samsung Galaxy device running One UI (Android 9.0 Pie).
Google moved the clock to the left corner to accommodate phones with notches, and Samsung kept this change, but Galaxy phones dont have notches. So if youd like to put things back the way they were, you just need to install an app called SystemUI Tuner, send one ADB command (available in Step 5 at the full tutorial), then tap a couple of buttons.
If youre having any issues with the ADB stuff shown here, check out the full tutorial. There are links to other troubleshooting guides that can help get you squared away.
