Android phones and even tablets are sold in many different models and brands, some of a high level, such as the Samsung Galaxy S3 and S4, the LG Optimus or the Nexus, others a little shoddy, less expensive, slower. The slowness of the system and the low internal memory are the main problems of older smartphones and less expensive models.
Any smartphone you have, on all mobile phones, expensive and not, to speed up Android you can disable the animations of windows and transitions when you move between applications and screens.
These animations are visibly very fluid, but they also waste time on fast mobile phones in the transition from one app to another.
Disabling these animations speeds up the transition between the different applications open on the mobile and the passage between the various screens, saving time.
For this trick you need to access the Developer Options menu which may not be enabled.
To find it, open the Settings screen, scroll to the bottom of the list and tap About phone .
Scroll down to find the Build Number row and tap it repeatedly until the message "You are a developer now " appears.
Go back to settings and open Developer Options .
Scroll down until you find, under the Drawing section, the options: Window animation scale, Transition animation scale and Animator duration scale which have a default value of 1X .
These three options can be completely disabled to speed up Android or they can also be changed by speeding up the animations if you prefer to see them.
Animations can also be made faster without completely disabling them by selecting the 0.5x option.
The Animator Duration Scale option is the transition option when you open the application list.
To apply the change, you must restart the used launcher.
Then go to Apps from Settings, from the list of all Apps search for the launcher and terminate it.
Then press the Home button on your Android phone or tablet to restart it and notice how the transactions are now very fast.
The speed improvement depends on the Android device used.
On a very fast mobile phone like the Nexus 4, this change is very evident and you switch between one app and another instantly, while on slower phones the passage between one app and another can take a few moments in more.
This is in fact one of the reasons why Android and other operating systems use animations, to avoid delays in loading applications.
