How to Lock Your Android Device with a Contextually-Aware PIN

In this video, I'll 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, you'll 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 won't unlock your device the next time around. This isn't a lock screen replacement app, it just changes your PIN automatically. Even better, it doesn't require root or Xposed, and it will work on the majority of devices, so it's a great setup.

In this video, Ill be showing you how to unlock the hidden Night Mode setting in Android Nougat to get a blue-cancelling screen filter that works at the GPU level.
The first Developer Preview of Android 7.0 had this feature, but it was taken out before the final public build of Nougat was released. Luckily, though, you can re-enable this option with a simple non-root app, and theres even a Quick Settings toggle to help you control it.

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.

In this video, Ill be showing you how to the new boot animation from Googles Pixel and Pixel XL smartphones.
Its a pretty cool animation with a white background, unlike most. Four colored dots bounce around while its loading, then eventually morph into the Google G logo. This should work on any rooted device that has a bootanimation.zip file in its /system/media folder.

In this video, Ill be showing you a relatively unknown feature from Marshmallow TouchWiz on Samsungs latest flagship devices. This should work on the Galaxy S6, S6 Edge, Galaxy S7, S7 Edge, and Note 5, but only if youre running Android 6.0 or higher.
This Adapt Sound feature basically performs a hearing test on you, then uses that data to create your own personalized sound profile that will be applied system-wide. The end result is some of the best sound quality Ive ever heard on a mobile device, so its definitely worth checking out.
