Just another Update
Under settings Apps-You can activate Google Services Framework. Once that is done you can use G Apps.
a) Got the phone set up using a simple $25 plan (leveraging Boost Amazon). Obtaining LTE speeds and calls working great.
b) Have installed all my music apps and have downloaded music. Keeping the device clean of email apps, etc. As I want to keep this media centric, no distractions with notifications, etc.
c) The device was programmed to take any SD media as requiring a re-format prior to taking it. This is something that I have experienced with China based ROM's when a phone is involved. Once you re format , everything works fine.
d) Hiby music app works fine and does everything expected.
e) Using the device as a music player and as a phone. Have downloaded using the phone side only a bunch of playlists and everything worked well. Wanted to test if phone overheated vs using wifi. Everything good
f) The device volume (+/-) has a lot of steps , so works great to achieve very specific increases. This was compared against a Pxel Fold, Samsung S24 Ultra and One Plus Open. So it seems that they modified the hardware at that level to behave as a DAP.
g) Output (4.4) has a lot room for volume increase, using Trifecta , Volour , CustomArt 7U vs some dongles. I do not need to go over 30% volume. At 40-50% it was very high.
h) No noise or interference found, while moving between apps, etc.
Device weight, screen, having phone connection and 3.5+ 4.4 outputs.
Had a bit of bias , as I had to deal with Moondrop DSP cable app and its clunkiness, but it seems they applied some good focus on this device, I think its a great effort by Moondrop.
