For one thing, as I understand it USB Host\audio over USB must be enabled on the phone. I haven't been able to determine that this is the case with the Moto G5 Plus.
For another thing, I've read that even if those are enabled it doesn't necessarily mean I would be able to listen to music through streaming app software (i.e., Rhapsody\Napster\Spotify\Tidal). I might need to use a separate media player app (which would not have access to the streaming music).
If you don't mind, why do you say 'As long as it is on an Android version less than 8, it should work.' Is something going to change with Android 8?
I'm not sure if HiByMusic is updated for Android O. UAPP is however, so actually, you could use the DAC on O.
Streaming app software-wise, I think you need to be at Android M/6 or below. I don't think DAC's play well with 7 and up. You may need to be on 4.4.4 or 5.0 and up. I forget which is the lowest supported Android USB system audio version.
So uh, looking for a good little android compatible DAC/Amp with a super small form factor. Would anyone here be able to help out? Something like a Dragonfly or SMSL iDEA is as large as I'll go in terms of size. Budget would probably max out at like 70USD. I'm going to be using these with quite sensitive low impedance IEMs so low noise floor and a sub 1Ω output impedance are a must.
Currently looking at the hifimediy Android DAC simply because form factor. Would the iDEA be a better option? I've heard of issues with it with some buzzing or something. The physical buttons are quite enticing though. Other options would also be nice.

A couple things I forgot to mention, is that I'm going to be using these with quite sensitive low impedance IEMs. Low noise floor and a sub 1Ω output impedance are a must. I'll add it to the original post too.
Form factor is too big. I've currently got a Geekout 1000 which I'm in the process of modding at the moment anyway. Not sure how hot the 450 gets, but the 1000 gets to uncomfortable levels in use.
Not too trustworthy of Fiio to be honest. I've had an E10k which was really quite warm and hazy, and I've currently got an E18 which I'm currently trying to sell. The SNR only being 100dBA is a bit low too.

What root kit did you use? I have the same phone (S5 Neo) and getting no sound from my dragonfly through my OTG cable. The device recognises something has been plugged in, the dragonfly lights up, and it stops playing music from the internal speaker. But no sound through the headphones. I tried the USB host check, says that android.hardware.usb.host.xml is ok, the other two options have red Xs.
If anyone is interested, the new Pixel 2 USB-C to 3.5 headphone dongle measures pretty impressively for how cheap it is. https://forum.xda-developers.com/pixel-2-xl/how-to/pixel-usb-c-audio-measurements-t3691535
Super low output impedance with decent power in that form seems quite attractive, especially for how cheap it is. The issue seems to be the gain being too high though. If rooted or using UAPP it shouldn't be a significant issue though to my understanding. Going to get one myself and test out. Hopefully is good.

It's been a while since I used my Dragonfly, but doesn't it have some software controlled volume setting? I vaguely remember having a similar issue after using my Dragonfly on a computer, and after that, no sound when using it on my phone. Had to connect it on the computer again, change the volume there and after that it was ok again on my phone. But I'm not really sure, it was a long time ago, have hardly touched my Dragonfly (v1.2) since I got my AK70.
