Don’t download  and install the «NEON Codec 1.8.9 for Android 6+» usually suggested for MX player in order to support AC3 (available on Google play as «MX Player Codec for ARMv7 NEON CPUs»).

Instead, download the custom codec for arm v7 neon 1.8.6 (available here). Unzip that file, open MX Player, click on the menu …, go to  settings > decoder. Scroll down to the very bottom and select Custom Codec.  There, pick the file libffmpeg.mx.so.neon.1.8.6 you have just unzipped.

MX Player will next restart. You can now try a video with ac3 codec. Ex.: download a sample from here.

Et voilà.

When I used my headphones to play an Oculus gamen I thought that the mobile was not powerful enough to stream the sound via Bluetooth while playing the video. Weird, but ok… it was also not powerful enough to mirror the video on my Samsung TV, so….

But when it failed also to stream fluently music, either from YouTube or from by DS Audio Stations (Synology), I thought there should be a reason behind this.

As it’s known that Bluetooth and WiFi are both using the frequency 2.4GHz, I tried to disable the WiFi… and it solved immediately the problem.

I never never had such a problem with my previous mobiles Also, I am quite sure I would not have that issue if I could connect on a WiFi 5Ghz.

Support page for GS7 in Belgium is: http://www.samsung.com/be_fr/support/model/SM-G935FZDALUX

I did post a request for support to Samsung on the 2nd May and only got an answer on 20th May. I said that the noise was awful when the Wifi was on and great if it was off. I also said that I had not such issue when streaming from my 300€ OnePlus One mobile (the S7 was 799€) or from my Sony Laptop or from my Lenovo Tablets.

They answered that “Samsung does not guarantee the proper functioning of Samsung products. with other branded”

WTF Samsung! Wi-Fi and Bluetooth are standard wireless protocols. My headset works perfect with 3 other brands.

Android Marshmallow has the ability to take a SD card and partition it as semi-permanent device storage. But it’s not accessible on the Samsung Galaxy S7.

I applied this recipes with success: http://www.modaco.com/news/android/heres-how-to-configure-adoptable-storage-on-your-s7-s7-edge-r1632/

• Download and Install “Samsung Usb Drivers” from http://adbdriver.com/downloads/
• Download and copy in a folder the “ADB kits” from http://adbshell.com/downloads
• Enable the “Developer Options” menu via Settings > About Device > Software Info > Type 5 times the “Build number”.
• Enable “USB debugging” via Settings > Developer Options.
• Plug your mobile into your PC via an USB cable.
• Open a command prompt as administrator and type adb shell
• Type next sm list-disks to see the Disk ID. It looked like this on my phone “disk:179,0”
• To use 100% of the SD card as internal storage, type sm partition <Disk ID> private
  • Ex.: sm partition disk:179,0 private
• After formatting the microSD card
  • Reboot
  • Go next into Settings > Storage. Select the “SD card” and hit the menu “More” to “Migrate data”. This moves everything to the SD card. Everything in the future should install to the SD card until it is full and then moves to internal.

Before this, due to Oculus VR stuff, my internal storage was full although I already moved manually most Apps to the SD card. Now, after the “Migration of the Data” only 18GB are still used out of the 32GB (~13GB have been moved to the SD Card).

NB.: Since I did this, I notice that moving Apps to the SD often results in an error message : “Not enough storage space”. I usually just retry and then the move succeeds.
