Re: [Linphone-users] Android: audio in bursts (overrun, purging)

[Guillaume BERAUDO]

Hello,


I have also bought a Galaxy S 2.1 and was surprised by the quantity of
debug and errors found in the logs. It seems to me that Samsung
released their phone too early; without finishing debugging on their
part.

After a flash to the 2.2 froyo firmware version provided by Samsung on
their website the situation is much better and linphone is quite usable.

Thought it might be possible to workaround these Samsung bugs, I
recommend you to upgrade your phone to the froyo firmware. Here is the
Canadian page for it: http://pages.samsung.com/ca/froyo/English/
