There are lots of different software that you can use to download from the internet to your Android device. The only thing that you have to understand is that it is entirely up to you as to which software that you download or install on your phone. One of the things that you have to keep in mind is that you need to ensure that you download a software that is compatible with your particular version of the Android Operating System. When you download the software it will typically offer you an option to download it for free or for a fee, it is really up to you which one you choose.
The reason why I say that you want to download the free software is because when you download the free versions of the software you will get a trial version which you can use to see if you would like to download the full version later on. When downloading the free software you will be able to check out how many days you have left to use the trial period. Most of the time you can get a good idea about how much money you will be spending on the full version and which ones would you rather use.
After you have downloaded the software you can install it onto your phone by first going into the Android settings on your phone. Once you are in the settings go into the Applications tab. You will then find the BT Controller application. You will need to click on the software and select Install and then from there you will be able to install the application. Remember that you want to ensure that you download a compatible software to your Android Device, and this is something that you have to do if you want to make sure that you are not wasting your money.
