But you use it for Clash of Clans and win 6 stars for our clans   

I once saw people taking photos using Mi3 in previous threads, for me quite amazing leh the photos outcomes.

Taking photos at night time, and dark areas, still look very clear....my phone and ipad cant even take photos at dark areas lol, so many noise and cant see anything at all

Tried the snooze thingy with my current Mi3 (Latest Dev ROM) & spare Mi3 (Stock MY ROM)
I can confirm that on both ROMs, the snooze "X" are there.

Screenshot 2: Mi3 with latest Dev ROM


So it must be something else that caused the "X" not to appear on your phone. Maybe there's a setting that was turned off?
Yes, definitely worth it 
Every company takes our data but I think the issues raised in the forums about Xiaomi & Baidu was that they never disclosed anything nor what are their plans with the data.

At least with FB for example, we know they're using it to have targeted ads for more revenue streams.

If you use latest dev rom with kitkat & google camera, you can see a lot of difference.

The problem is in the algorhythm of the camera rather than the hardware itself.
I don't think Xiaomi have a dedicated image departments like Sony or Lumia, hence the mediocre performance on stock camera

i'm not really keen taking pic but u're too exaggerate bout s3 > mi3. i tested mi3 produce better quality but not much as we see. r u sure ur camera setting correct? do u need someone to teach u how to capture pic?
