How to enable louder speaker volumes on HTC EVO 3D
A couple weeks ago, we showed you how to change the Sprint banner on your HTC EVO 3D, giving you yet another way to personalize your phone, no root required. Here's more good news: if you are one of the early adopters who has been complaining of low volume levels on your phone, you'll be pleased to know that this same method can be used to increase the maximum speaker output on your EVO 3D, again with no root access necessary.
As a reminder, the process is a bit involved, but can be completed relatively quickly. You will need your MSL code (we provided some tips on how to obtain this six-digit number in a previous tutorial) and QPST installed on your computer.
To get started, you will need to connect to your phone through QPST. Slayer69 has a great tutorial (steps 1-8) if you need guidance with this. There are also some helpful guides at the end of that tutorial if you run into any problems obtaining the right modem drivers or getting the COM ports lined up correctly, both of which happened to me the first time I tried this.
Once you have completed the first eight steps of Slayer69's tutorial, just click on the Sounds tab in QPST. Here you can change the maximum allowed earpiece, speaker, and ringer volumes, as well as the key beep, speaker beep, and speaker ringer. You can see what settings I chose for myself in the image below.
Please keep in mind that it might be possible to blow out your phone's speakers – or your eardrums – if you set the maximum volume too high, so I would not recommend anything above a 3 in all settings. As you can see, I was more conservative than others and kept some of the defaults the same, only upping the volume one notch on my speaker, ringer, and earpiece volumes.
Additionally, if you scroll to the right far enough, you will find another tab labeled MM Audio in which you can adjust the volume output when using standard earphones. I encourage you to play around with the settings and find out what works best for you, which might be different than what works best for me.
Once you have selected your settings, click Write to Phone and wait for your phone to reboot. (Ignore any read errors you might encounter, as these are normal and to be expected.) And as always, remember to keep a backup of your phones original settings before making these changes permanent. QPST makes this easy; just click Save to File in the lower right before changing anything.
How is this adjustment working out for you? Are you able to enjoy your videos and music a bit more in louder environments?
