Exploring the Unique Android Alert Icon: A Nostalgic Journey with Sony Xperia Phones
The icon you are describing sounds like the Do Not Disturb mode alert icon on Android devices. The circle with squiggly lines in the center represents the sound or vibration settings, while the small dot at the top center often indicates that Do Not Disturb is activated.
The Do Not Disturb Icon
If you see this icon in the status bar, it means that notifications and calls may be silenced based on your settings. You can usually access and modify these settings by swiping down from the top of the screen to open the notification shade and tapping on the Do Not Disturb icon or by going into the Sound settings in the device's main settings menu.
Sony Music App and Xperia Phones
That app is the Sony Music app. If this is the app you refer to, you likely have a Sony Xperia phone. Xperia was the first line of phones to offer water and dust resistance starting with the Z1, and it even included screen recording capabilities. I used an Xperia Z3 for about 4 years and played around with augmented reality back in 2014 with the Z3. Although I now use an iPhone X Pro, I miss my Xperia phones.
Why I Love Xperia Phones
Unfortunately, my Xperia phone broke down, and my wife gave me her iPhone 7. She then upgraded to an iPhone X Pro, and now she has handed the phone to me. However, I hate it. The Sony Music app came pre-installed with my Xperia Z2 and Z3, initially called Walkman, and later renamed to Sony Music. It is a powerful music player.
Context and Usage
Notifications in the status bar represent active applications. Sometimes while using a headset, you click the play music button, and the player starts to play in the background. This could be the preferred or default music player which causes the app to start every time you want to listen to music.
Xperia Specifications
Let's go through some of the specifications of my 2014 Sony Xperia phone. Although the phone had limitations, it was impressive for its time. Here are some pictures taken with the phone to give you an idea of its capabilities:
Panoramic Picture of a Mets vs Brewers Game
This is a terrible attempt at a panoramic picture of a Mets vs Brewers game. Jose Reyes was batting. Any shortcoming in this picture is blame on the photographer, myself, not the phone.
Bay Near Battery Park, New York
This was supposed to be a 3D picture. However, it looks more like a ghost image than anything else.

These graphics could walk around and make noises. Before comparing the phone to modern smartphones like iPhones, please refer to the specifications of this phone, a Sony release in 2014.
Color Inversion Shots
My favorite: I used to do this all the time on my Z3. The phone did a good job at removing all the colors from the environment, keeping only one specific color. At night, this shot shows the 47/50 Street F D M lines in Manhattan. I have another one showing only orange, but this is my favorite.
In conclusion, the Xperia phones, especially those from around 2014, were remarkable for their time, offering unique features and enhanced user experiences. The Sony Music app and its distinctive Do Not Disturb icon are just a few examples of the innovative features they provided.
