Wiko Cink Peax 2 black image since 2.4.7 (Bug #3596)

hello,

I'm working with a Wiko Cink Peax 2 dual sim phone and notice a strange behavior of Native Camera since OpenCV4Android v2.4.7

If there is not enough light, the camera adjust the brightness but the image becomes black soon.
Pointing it to the sun or a bright light shows that there is still a live image but very very dark, like what you can see with eclipse (the sun behind the moon, not the IDE...) glasses.
The image stay "black" even after restarting the application.
Sometimes, reseting the APN with the Photo application helps but not always.

I noticed this on a Wiko Cink Peax 2 device with OpenCV4Android 2.4.7 and 2.4.8 and sample project from OpenCV4Android.
Downgrading to 2.4.6 solves the problem.
Other device like Samsung Galaxy S2 or S4 are not affected by this issue.
Moreover, the same code work with 2.4.6 and not with 2.4.8.
And on the device, OpenCV Manager is installed from the Play Store with version 2.4.8.

Wiko Cink Peax 2 is running Android 4.2.1 (like Samsung Galaxy S2).
