background PNG colours are braking

background PNG colours are braking

I’ve recently started my journey with Cocos2d-x and so i’ve encountered first issue that i can’t find solution for.
I’m setting background:

CCSprite* pSprite = CCSprite::create("menures/background-001-grey.png"); pSprite->setPosition(ccp(visibleSize.width/2 + origin.x, visibleSize.height/2 + origin.y)); this->addChild(pSprite, 0);
image in attachment.
There is light radial gradient in the middle in the image.
When i’m testing apk on my phone the image has color aureola (circle) that can be easly visible.
Also vertical stripes colors seems to be a bit broken as well.
(Sorry i can’t provide image)
looks like color depth is too low.
Are the PNG files has to be saved with special options to be displayed correctly?
Thanks in advance for help.
