Fix audio playback issue. On some phones volume is extremely low through the android app

[mattixpet]

• Here is an idea: Some phones simply have poor playback unrelated to any app. Letting the app fix things is a bit heavy handed. Might it not be better to attempt to fix these issues by other means first, such as:https://www.androidpit.com/improve-the-sound-and-volume-quality-on-android - Sveinn
• What phones? Has it been established that this is not a phone issue. How was this issue established. Need a phone that works well and a phone that performs below standard. Does this issue affect recording, thus impairing data quality? Is user experience sufficiently impaired - is it affected? - Sveinn

ASR cant recognize these recordings properly because it has a lower signal to noise ratio

On java there were many different types of phones, some of which couldnt handle the app requirements
