Hello Peter,

I am using V9.　I understood the situation.
Thanks for your reply.

By the way, my V9 cannot get camera settings from yesterday.
Network connection has no problem, but my app always show
message "Network connection required to initialize camera settings. ..."

Do you have any idea?

Hello Radix,

Are you using the ZTE V9 or the V9 Plus? The V9 will not be able to render 640 x 480 because it has a 600Mhz CPU. The ZTE V9 Plus should work at 640 x 480 without a problem.

Thank you,

-Peter
