With the definitive arrival of Android 11 we have been able to see countless changes that visually make us have new possibilities available to users, although however we have not gotten to know everything in depth. Google usually keeps a series of aces up its sleeve with which to implement functions in the next Google Pixel or with which to improve some of its services.

In other versions we have seen how the company made this same movement to give more possibilities to the customization layers since all the changes from Android 10 to Android 11 that we have seen will not finally reach EMUI, MIUI or the One UI layer among others. . Perhaps some of the functions that we are going to tell you now does end up implementing them in the customization layers.
Android 11 source code uncovered
Since we are dealing with an open source operating system, one of its possibilities and advantages is that any user has access to everything that the system includes and already from the first beta version of Android 11 we could see details of great interest, trusting in which they were implemented but have finally remained in limbo.
Drastic changes to control volume on Android
Until now in Android we had to settle for three volume sections that correspond to tone, multimedia and alarms. This was somewhat limited and made its use very complicated, but in the internal code of Android 11 indications have been found that it will try to implement a system capable of differentiating volume levels by applications. In addition, the audio systems can be combined, so we could be listening to music and at the same time listening to the voice note of a friend.

Android volume systems will not stop there and volume systems have also been found directly designed for mobile assistants, it is not known if it is a volume option of its own or another type of novelty, we will have to wait to know it.
Freeze cached apps
Sometimes the additions that reach the Android betas leave us speechless and this is one of those occasions. As has been discovered, the system will try to freeze and limit access to applications that remain in the cache at certain times and then unfreeze when removing them from the cache, an option intended for developer mode.
Custom watches
Although the Google Pixel already had the possibility of giving a different style to the clock of the Always On Display screen, it seems that this option will be implemented in the rest of the devices. This would come from the hand of Android themes, an option that allows us to modify colors, text and many other options on mobile phones.

Blur when accessing notifications
When we slide the notification bar on some smartphones we can see how the rest of the screen darkens and what the source code of Android 11 has let us see is a system that blurs it. This option is not currently available and we will have to wait yet to see it in action.
Gabeldorsche
A curious name so it is a function that manages to give stability to bluetooth networks, thus improving the connectivity of our mobile with home automation or other elements.

5G auto shutdown
One of the problems in 5G connectivity is battery consumption and in Android 11 we have been able to discover that there will be an automatic option to turn it off when we are not using it.
