# 🎧 Bluetooth Volume Lock
📘 [Read this in Spanish](README.md)
**Bluetooth Volume Lock** is an Android service that **keeps your media volume steady** when you connect Bluetooth headphones. On Android 15+ (API 34), the system automatically reduces the volume to a "safe level" when using headphones at high volume for a prolonged time.
> This app solves that issue by restoring your original volume automatically — ideal for gym sessions 🏋️♂️ or extended headphone use.
---
## 🔧 Features
- ✅ Monitors Bluetooth connections
- 🔊 Restores original media volume if Android lowers it for safety
- 📲 Runs as a **foreground service**
- 🧪 Currently compatible with **Android 15 (API 34)** only
