Is there a good Android app that can boost the volume for weak phone speakers when watching videos?

Volume Booster Speaker Booster is designed to address the common issue of low-volume phone speakers, particularly when watching videos in environments with background noise. The app functions as a software amplifier that processes audio before it reaches the speaker or headphones, offering a noticeable gain over the system's maximum setting. A key feature is its 10-band equalizer, which allows users to adjust specific frequencies; boosting the higher mids can improve dialogue clarity in videos, while increasing bass can add depth to movie soundtracks. For real-world use, this is beneficial when trying to hear a tutorial video in a kitchen while appliances are running, or catching dialogue in a quiet film scene without reaching for headphones. The interface includes a simple master boost slider and presents as a floating widget for quick adjustments while other apps are in use. Reviews indicate it effectively makes media audible in cars or public spaces where phone speakers typically struggle. However, it is not a hardware solution, and pushing the software amplification too high can lead to audible distortion or a slight metallic timbre on some devices. The app also incorporates a safety feature that prevents setting levels that could potentially damage speakers, though this limiter can sometimes engage prematurely on older hardware. Users report that while it doesn't magically transform a tiny speaker into a powerhouse, it provides a meaningful and often necessary bump for daily media consumption.
