Boost Speaker/Headphone Volume of Any Android Device

The reason Android is prospering over other mobile operating systems is simple to understand; it offers a lot of flexibility. While a lot of people prefer using Android as it is out of the box, there are people who are always pushing their devices to limits just in order to have the best possible performance.

Today, we are going to look at a case that has been brought up time and again. For those who don’t know, smartphone manufacturers ship their phones with some tweaks. For instance, the audio output of your smartphone is always toned down for safety. While a regular consumer may not pay much attention to this, people who prefer music on their smartphone can be despair because of this.

Luckily, the tweaks made by the manufacturers aren’t hard to reverse engineer at all. After all, the stuff that has been tinkered with is already present in the device, all you need to do is make some changes in the right values and you can have the accurate audio output your phone is designed to give. If you are willing to increase the audio output of your Android device, simply follow the guide below.

Note: The process has been tested on LG G4 (Intl.) and Sony Xperia Z2. It should work on other Android devices as well but we do not take any responsibility for the damage that your device may face. It is advised to make a backup of the original file. Your phone must also be rooted.
