Cocos2d-x Version 2.2 CCRenderTexture does not play the image correctly on the Samsung Tab 4 tab (Model No. SMT231)

Question

I am trying to use strokes moved with Render Texture. This is my code:

void GameplayLayer::visitSpriteContinuously()
{
   CCRenderTexture*    canvas = CCRenderTexture::create(screenSize.width,screenSize.height,kCCTexture2DPixelFormat_RGBA4444);

   canvas->setPosition(ccp(screenSize.width/2,screenSize.height/2));
   this->addChild(canvas);

   GameSprite* drawSprite=GameSprite::gameSpriteWithFile("circle.png");
   this->addChild(drawSprite);

   CCPoint start = starttouchPosition->getLocationInView();
   start = CCDirector::sharedDirector()->convertToGL(start);

CCPoint end = starttouchPosition -> getPreviousLocationInView();
end = CCDirector::sharedDirector()->convertToGL(end);

float distance = ccpDistance(start, end);
canvas->begin();
for (int i = distance; i > 0; i--)
{
    float difx = end.x - start.x;
    float dify = end.y - start.y;
    float delta = (float)i / distance;
    drawSprite->setPosition(ccp(start.x + (difx * delta), start.y + (dify * delta)));
    drawSprite->visit();
}
canvas->end();

}

I get the desired result on almost all Android devices that I tested, except for Samsung Tab 4. On the 4 tab, the sprite drawn is in the dotted image, even if the used base png image is solid. I searched a lot, but I did not find anything useful. If someone has seen similar problems and has a solution, please let me know. Below are the screenshots:
