Problem whit some option on my MX4

Guys… I have problem with my MX4.
I just downloaded the Puffin Web browser.
Then when I open the application there was an info that, when if I want to start the browser must disable the Force GPU rendering in developers options. But, when I go to dev options there is nothing like the GPU rendering settings on my MX4. My firmware is 4.0.3U.
Please help 8-)

Hi, open the Dialer and type *#*#6961#*#* it will add more options in the developer menu ;)

Ok. It’s done and work properly.
Thx for solution (^_-)
