Cayin i5 Lossless Android DAP with AKM4490 DAC supporting 32/384 PCM + 64/128 DSD

So far, the Bluetooth performance on the i5 is not very good. For whatever reason, the pause/stop button does NOT WORK with any Bluetooth capable headphone I have used and in several cases the next and or back button doesn't work. Please keep in mind I am using 2.3 Beta, but I had the same issues with 2.2. Anyone's experience any different or the same?
To answer your question, test them before you buy them.

I found that only some of the controls on my backbeat pro headphones worked with the built in player, but they all work with foobar, so I guess the problem is software rather than hardware?

Quick question on other DAP's (Onkyo, Pioneer, Astell Kern) when you get to one of your main music folders with sub folders there is always a Play All feature, this makes it easy to just play everything within the main folder however I can't figure out how to perform this type of action on this unit. Any thoughts?

It seems that all the same the development of new modified firmware for our player is stopped . Because a new budget player N3 constantly come out with new firmware with new features . For our player only made the possibility of going back to 2.0 . Surprising that the player runs on Android and has the complexity of the design , even though students are able to modify the firmware for their smartphones . I have now is a 2.3 , but even this firmware has bugs that are annoying for every day . The main error in this firmware is a non-entry from the song to the next song . Next
error is to stop the music at any time . In General I am disappointed with the purchase of such an expensive product with such raw software !

We didn't stop because of new products rolling out. The i5 firmware is not making any progress because the MCU company Leadcore has decided to pull out from portable audio market, without their solution support, we can only treat the MPU as a legacy system and develop codes to wrap around it, this is going to take a long time for minimum progress, or we even failed to solve the problem no matter how hard we tried.

In case you are unfamiliar with the semiconductor industry, when we adopt a MCU into our product, we don't own all the intelligent or associated coding, we obtained service from solution provider and Cayin, or any other manufacturer in HiFi industry, don't have the necessarily competence to deal with the semiconductor shop directly, that's why we need to rely on solution provider.

The N3 is based on a MCU from Ingenic Semiconductor, we are grateful to the support we have received so far, and that helps the firmware development task tremendously.
