You could also use a custom kernel that would allow you to add fq_codel/cake then add custom rules to it.

I would advise a setup such as: AFWall to run scripts depending on whether it's WiFi or Mobile (3G/4G). The script would be a simplified debloat.sh just adding simple tc fq_codel/cake commands.

I tried this before on the Samsung Galaxy Nexus back on 2013 [1] [2] with AK_Kernel. I had interesting results though mixed ones. It was mostly due to mobile data quality being awfully varied. Therefore, I wasn't knowledgeable to find a good script setup that catered for all the moving parts. Nonetheless, it improved my situation. I recommend it.

I've been meaning to try this again using a modified Franco kernel [2] for Huawei Nexus 6P. However, as with everyone else, Real Life(TM) has a tendency to get in the way. :) I don't use custom ROMs. It would be a stock Nexus ROM installation, SU root for scripts/tc and custom kernel for fq_codel/cake kernels.

We could try if people are interested. However, I can only be of help after November.

I went further, and rooted the android phone.

Then I set the txqueulen to 0 on ccimni0 and wlan0.

Here are the results:

Despite disabling the txqueuelen, The inbuilt TX/RX buffers are still
pretty high:

#define CCMNI_TX_QUEUE 1000
#define CCMNI_UART_OFFSET 2

So my idea is to reduce the size of the queues so that it's just
enough for 21Mbit/s (down) , and 4Mbit/s (up), in the absence of BQL
support.
