Summary: it doesn't work with my phone. Do others work with the Samsung Note 9? Shoukd qi get an LG V20? Or should I just stick with headphones?

Long version...

I bought this item as an introduction to high quality sound and have spent 6 hours trying to get it to work on my 3 devices. It has worked at least once on each, but repeating what caused it to work wouldn't work again. So I am wondering if it is a defective unit before sending it back (e.g. maybe there is a fault making it not send the right information to my devices or a wire is loose?). I am in Vietnam and it was shipped from China and returns need to be for broken products and done within 7 days. I am hoping someone can reassure me it is broken or something else, please.

Main device I wanted to use it on is a Samsung Galaxy Note 9. Also tried on Dell XPS laptop running Windows 10 (edit: it works on this now after updating firmware) and a Samsung Galaxy Tab S7 Plus (too tired to try again but didn't get to use with this anyway).

I have been Googling solutions and watching videos. Then menu diving trying loads of different things. Anyone know if Samsung devices don't work well with these? If so should I buy a different brand or will I need to buy an MP3 player or switch phone? I have earphones and open ear headphones on the way, so I would be willing to switch phone. The LG V20 seems to be the best, apparently the DAC/AMP isn't needed on those phones. The DAC costs more than the budget headphones and earphone, if I could get a refund that would almost pay for an LG phone.

With my phone, the only way I can get it to work consistently is to restart the phone with it plugged in, but if I unplug it to charge then it won't work again.

The headphones I have ordered have 32 Ohms and 25 Ohms impedance, so maybe I don't need the DAC/AMP? I read they are needed for ones that go over 32 Ohms. Although it sounded much better on some songs with the headphones that came with my phone.

I am a total noob to this so any advice would really be appreciated. I was into Hi-Fi 25-30 years ago and haven't had good sound quality since. I really want to try and get close to that Hi-Fi sound with headphones whilst traveling. I currently get to plug in my old Hi-Fi once every 2 years when I visit the UK and it is bliss. I am sick of the poor sound on JBL Bluetooth speakers.

They have confirmed it won't work:

"If you mainly use the DC03 with your Samsung, the DC03 may not suitable for you. We don't have a solution to work with Samsung without reboot.
