I've had the DFB working on Android 5.x. I couldn't get it working on an old Galaxy Tab either and that was running 6.x so it isn't about software version but has more to do with the way Samsung has set up the audio output routing.

Not everyone wants or needs Root for anything else; it was just offering a way of doing it without root. If you want or need root then you can install through TWRP; apps that are used to remove system apps or freeze apps only work with root so it can be useful to have.

I've done it like this without Root but you have to use the mount /system option in TWRP before you can see the contents of that folder.

I rarely use Bluetooth headphones but do have some cheap TWS IEMs (Enacfire E19), I have no issue when using them with my phone, tablet or laptop but I also suffer frequent dropouts with the X5iii; I've seen similar comments from others on Reddit so I suspect that this is a connection issue with...

1TB cards are available now, the first genuine cards were announced quite recently although I think they are priced around £500 so probably $500 in the US.

Are there no capacitors in the circuit to smooth the voltage/current from the USB supply to electronic circuitry?

I think you need to revert back to the original stock recovery before upgrading. You can use the Android Tool to reinstall the stock recovery, go through the update process and then use the Android Tool to reinstall TWRP and custom kernel (and/or root) if that's what you want.

I had the same issue on an old Galaxy Tab A. It works with UAPP and on a rooted device I could see the DFB using ALSA but the L&R channels were both set to 0 and attempts to set them to anything else were met with an error. I had a similar issue with a Topping DAC/Amp on a Moto G device so it...

Is Root needed for the scripts to run and for the features they bring to work.

The DFR/DFB aren't without their problems, when used with Android devices the volume control doesn't work properly unless you are using UAPP or go through a bit of a hack process on a rooted device. Volume control in Windows can also be an issue as it can get too loud without sufficient room for...

I wonder if you could just install V4A on a rooted X5 3rd Gen.

I was running it for around 3 hours after installing the new kernel. A mixture of locally stored files and some streaming from Spotify. The unit got warmer than usual but not hot and certainly not hot enough to worry me; I've had phones get hotter. I will try flushing the cache though to see if...

Glad it's not just me. I am on stock firmware but with the new kernel and also noticed that my device was running warmer than usual. Not to the point where I would be overly concerned and it didn't seem to be having a significant impact on battery but still warmer than with the stock kernel.

If both devices are sending a bitperfect signal to the DAC then there should be no difference. If one or both devices are doing any EQ, resampling or processing of any kind before passing a signal to the DAC then there may be a difference if the data is different.

Fiio have mentioned in the past that they don't buy in the sort of volume required to get a deal with Qualcomm on the Snapdragon processors. If the processor/memory pushed prices too high they would probably price themselves out of the market. There is no reason why Android 5 can't be the base...
