How about boosting the priority of the application?

Is there a /sbin/tc binary on your system for lartc.org Traffic
Control or Quality of Service for network packets?
Have you tried turning off all other users of bandwidth on the phone?
Balancing little packets with big packets is tricky.

If simple priority and or niceness decreases do not work nor QOS, then
it may be the type of queue used.  There are many types of queues.

Then again, in theory the manufacturer could be providing better CPU /
DSP service to cellular service provider software.
