Has anyone seen the download link to the new FW 2.0.2? It's supposed to be released but maybe I'm too eager

You should go to the phone Bluetooth settings, not the Developer Options. See my earlier post here.
Stock Android 9.0 does not have that option. All Android phones are not alike. For example your Samsung is way off the stock Android UI.
On stock/standard Android you can set HD audio on/off in the BT menu but that turns off both LDAC and Apt-HD so it switches to SBC

Which codec does it use when you have HD audio turned on? Check this in the EarStudio app, not Developer Options.Stock Android 9.0 does not have that option. All Android phones are not alike. For example your Samsung is way off the stock Android UI.

LDAC with adaptive bitrate

It should stay in that setting across multiple Bluetooth connections. Is it resetting to something else? Did you want to choose a different codec?
It does but I want 990kbps if I'm using LDAC which means accessing dev settings. I do prefer Aptx-hd since it's more true to the recording according to my ears. Due to this I have to access dev settings and enable Aptx-hd instead of LDAC

If I'm not wrong, the codec picked is best one by default if both player and receiver support it, so if player supports LDAC, this will be used.
On the other hand, bitrate (set as adaptive by default) and maybe bit depth (if you change it from 32bit to 24bit to match ES100 by some reason) are the values to fix between seasons.
This means that if the connection is strong enough, adaptive should play highest quality by default and no change in developer options is needed.
I use it by default, fixing bitrate only if I'm moving around and the phone is static and it works pretty well.

@wslee of Radsone said that under the LDAC license agreement with Sony, the ES100 must connect on LDAC whenever it is available on the source (that's why in the EarStudio app you cannot uncheck LDAC codec). However, Android only has one setting "HD audio" that enables/disables both LDAC and aptX HD at the same time. Android doesn't have separate settings for LDAC and aptX HD. When both are enabled, ES100 must choose LDAC because of Sony license agreement. Therefore it isn't possible to make it default to aptX HD. You can force it in Developer Options but only for the current session — Developer Options were only designed for developer testing.
Yes, and back to my original post about this; thats why i would want a widget that can set these settings for me
I'm thinking maybe i can ask Radsone to release a FW without LDAC to get around this problem.
As i stated a few pages back, LDAC does something to the sound. It adds room. Sure it sounds nice but not correct according to my ears and tests.
Oops I'm a little late...just noticed that Smorgar just anounced it earlier.
A new ES100 firmware v2.0.2 (Jan 2, 2019) has been released. I've just updated my ES100 with v2.0.2 firmware along with the new v1.9.0 update for EarStudio mobile app. Didn't notice any changes except the 2 seconds power button startup time. Have anyone here updated to the latest version yet?

I updated too, no problems at my end
I'm testing the new FW + app right now and it feels better with 2 second power button.
Other than that i see a few changes in the app. Ofc new EQ and more presets available but also a small change to the over sampling buttons.
Big thanks to Radsone as usual!
Funny side note: I'm looking to get a DAP but i have to pay so much to step up from ES100s sound signature that im thinking there is no point in spending the big bucks for a DAP.

@wslee Any updates on the non-Bluetooth ES200? Have been looking at a Dragonfly Red on one end and Chord Mojo on the other end but have been waiting for more specs on the ES200. Also curious if it will do MQA.
Thanks and Happy New Year!
