Astar Y3 chinese tablet , problems apps freeze and slow especially when on WIFI

Hello
In short
-There may be a kernel issue with the WIFI/BT driver / Any way to fix it?
-Multitasking not working, only one app may run if at all. Apps start slowly and freeze from time to time.
Recently I bought a cheap chinese Allwinner A33 based tablet Astar Y3 or softwinner qt-7. It's really slow when connected to wifi (module rtl8723cs) and i've began suspecting that it's a driver issue in the android kernel. As an offline device it may work when background processes are disabled from developer settings. Is there anyway to find a better ROM for this device, currently running 4.4.2? It has 2 GB ROM, and 1 GB RAM. Any ideas? Has anyone succesfully made this piece of junk work?

[HELP] Capturing audio data and save to raw PCM file in AudioFlinger

After some research, I find out this is possible to capture the audio data in libaudioflinger of Android.
I think the audio data is being written to HAL in here:
Code:
ssize_t framesWritten = mNormalSink->write((char *)mSinkBuffer + offset, count);
Full code: android.googlesource.com/platform/frameworks/av/+/lollipop-release/services/audioflinger/Threads.cpp#2118
I'm sorry, XDA don't let me to post the link. So I need to remove the https.
So, I would like to save the
Code:
mSinkBuffer + offset
to a file (which I expected it will be raw PCM audio file). I using those stream to write it to file:
Code:
std::ofstream audioData ("/data/audiodata.raw", std::fstream::app);
audioData.write((char *)mSinkBuffer + offset, count);
audioData.close();
The file is successfully written and it has data in it. But, when I play the PCM file (audiodata.raw) with aplay or ffplay, the only sound I got is noise.
Code:
aplay -t raw -c 2 -f S16_LE -r 48000 audiodata.raw
I was worry about the config of aplay. So I print some log of the libaudioflinger:
Code:

10-07 10:14:54.576 1300 1366 I AudioFlinger: Audio source: 0 (default)
I don't know what I did wrong. I have no idea why I only get the noise when play the file.
Any suggestion is much appreciated. Thank you in advanced!

I updated the full log printed out from AudioFlinger.

Could anyone please help? I'm not sure if I posted to correct forum section, so I would be appreciated if any Moderator can move this topic to where its belong.
