How to Enable Developer Options on Android & Pixels (6 Secret Android Tips)

Question

In this guide, I will show you how to enable developer options on Android & Pixel, in order to activate a couple of useful and interesting features.
 
First of all, I would like to point out that in this section of the settings, nothing should be modified 'at random' but only with competence and knowledge of the facts.
 
The paths indicated below may be slightly different for the various Android devices, I describe the items of the Pixel, which are identical in many Android smartphones; however, if you cannot find them, ask for help here ;)
 
Enable Developer Options
First go to Settings/About Phone
At the bottom you will find Build Number, tap it 7 times and a message will appear telling you that you have become a developer (if only it were that easy to become one XD)
 
Access Developer Options
Now go to the new Settings item in Settings/System/Developer Options;
You will find a large number of options, I repeat: DO NOT TOUCH ANYTHING YOU DO NOT KNOW.
 
Useful Developer Options
The options I want to present to you are these 5:
 
1 USB Debugging:
 
This is an option that is rightly hidden because it is dedicated to developers, but it is recommended to activate it, as it could give you the possibility of saving your Pixel, or the data contained in it, in various situations, such as a non-working touch screen or operating system that no longer starts. Activate it, then connect the Pixel via USB to your usual PC and you will be asked to authorize USB Debugging for that PC; you will need it to be able to connect it in the future, in case of a broken screen ;)
 
2 Windows Animation Scale/Transition Animation Scale/Animator Duration Scale
 
These, which are actually 3 options, establish in substance the 'duration' of the interface animations. You should find 1 in all three options, set to 0.5 and your Pixel will have animations that are twice as fast ;) If you put 0, the animations will be completely deactivated, greater speed of use of the smartphone, but slightly too drastic passages between the various screens, at least for me ^^
 
3 Default USB Configuration
 
Another very convenient option, it will allow you to choose the default behavior when connecting the smartphone to the PC's USB (charging, file transfer, etc.)
 
4 Background Process Limit
 
This option allows you to set the maximum number of background processes that can be running simultaneously. Reducing this number or setting it to "no processes" can improve the responsiveness and speed of your smartphone, but it will also come at the cost of multitasking capabilities, as background apps will be automatically closed. Limiting the number of processes can be useful, and I recommend setting it to 3 or 4 for older and slower smartphones
 
5 Predictive Back Animation (Pixel Exclusive for now)
 
Try to activate this Option, you will have a new 'back' animation, really helpful, give it a try!

6 Gemini Nano Running Locally
 
Great news! As of 5/30/2024, it is now possible to enable support for Gemini Nano running locally, rather than sending all of the processing required for AI features to Google servers where they are actually executed.
The option to enable is AICore 'Enable on-device GenAI Features'.
If you need, i did a VideoGuide

That's all for now, if there is interest I will try, from time to time, to give information and explanations for all the other Developer Options.
Greetings to all.
