[Linphone-developers] no built-in echo canceller on samsung GT-N7100?

[alex tuca]

hallo, 

i have samsung GT-N7100 android phone (rooted with lineage os) and was 
wondering, why linphone does not find a built-in echo canceller on this phone, 
all my samsung phones work with built-in echo canceller.

is there possibility to make it work? or to list all possible devices? or how 
to check if the echo canceller is really not available for this device? 

best alexander
