[Q] Increase bluetooth bitpool value on samsung galaxy s3 i9305

hello everyboday.

i realized, that the bitpool of the samsung galaxy s3 is set to 32 as default.
it seems, that the value 32 is too bad for a2dp with my bluetooth headphone.

I found the file where we can setup the bitpool, but i don't know how to edit android .so files.

the file name is audio.a2dp.default.so

the location of the file is.

/system/lib/hw/audio.a2dp.default.so

does someony know how to edit .so files.

Thanky and sorry for my bad english.

best regards

Sufeng
