Enable Developer Mode

1) Enable Developer Mode

Ok, this is one of the more widely known tricks, but it’s important nonetheless, so we are going to
include it.

       

Navigate to Settings > About phone and tap on your phone’s build number seven times. You’ll get an
 onscreen countdown, eventually followed by a message saying “Congratulations, you are now a developer”.

2) Change the Animation Scales

For the most part, the latest Android phones already feel very snappy. However, after the latest Nexus 5X only
shipped with 2GB of RAM, some users were left feeling a bit underwhelmed by Google’s hugely popular
product line.There are also lots of popular entry-level phones that come with slower processors and only
 1GB or 2GB of RAM.

One solution is to change your phone’s “Window animation scale”, “Transition animation scale” and
 “Animator duration scale” from 1x to 0.5x. Granted, it won’t actually make your phone faster, but it will
make it feel faster. Go to Settings > Developer options and scroll about two thirds of the way down the list to
 find the necessary options (you’ll need to have first enabled Developer Mode).

3) Clear App Defaults

It’s annoying when a link opens in a certain app rather than in the browser. It could be a YouTube link, a tweet,
or a Facebook page — you’ll end up waiting around while your phone shuts down Chrome (or your browser
of choice) and fires up something else.It’s easily fixed.Go to Settings > Apps and find the app that keeps
 opening. Once there, scroll down to Open by default, press it, and then select Clear Defaults.

If that doesn’t work, try doing the same with your browser app as well.
