@Jason Unfortunately my Micro-Sd was broken and cannot read on both AK and PC. Try to change another one , it's working well . Thanks

I was found the issue for 1.17 as before working well now cannot see microSD as photo. So I have updated 1.18 but still not solve.TT

My another is Fat32 still work fine but not sure his Microsd use which format , I also agree that should be re-format as DX-320x is very updated android system vs N8 which small CPU and long time ago . Anyway thank you very much .

No, I sold N8 to him and he already have DX320x .

I have read your issues for last night , thank you for replied me , But have some question as I have sold my unit to my friend that just take out 512 gb from DX320x and put to N8 player without format , so this bring error occurred freeze and the restart , I have check first he bring to much...

I have question that . can N8 format microSD by it self ? , or ant format suggestion as I,ve got crash issues on 512 sandisk Microsd . Thank in advance .

Just got my M4 impressed both design and sound quality Super matching with Sp2000Copper !!

Yes , warmer and more impact bass and drum on 18s , 😊😊😊👍

Audition A18s Demo with my SP2000Cu ,still prefer u18t as more open and more natural in high frequency , different tuning characteristic .

If i found this issues during audition I might not buy it , as pop noise before every track on mqa or switching sampling in dsd or hires file still occur that . IMHO Noise should not occur for the high level DAP like this

Same as my case cannot accepted as noise make me fright with IEM mqa File and Tidal .

That's why I'm sold out in 3 weeks . As look like Hiby cannot solve this issues so far from old model and R5 even R8 .

Yes corrected can't accepted anymore .

Moved to DX300 never heard pop noise (Hiby might optimize not good enough) really happy then , can't accept that as most of tidal is MQA always got pop noise .

I have try UAPP can’t see different , imo stock app better sound quality ,refund already .
