Yaa...i also face focusing issue with my device if you click red or dark pink object like flowers than the whole images is blurry...camera struggle to capture good images.
You're using portrait mode. Hello, haven't you heard that it's effect was intended for human faces and not for that thing? So obviously it won't work.
Same issue with my device.
1. you need more light. MUCH more light
2. Depth effect is added AFTER you take the shot
3. Portrait mode works best on faces!
4. Object is too close
