Mi4c Camera issues (blurry in low/fluorescent light)

After purchasing the Mi4c and waiting for it for three weeks, I keenly unboxed it and started tweaking the living hell out of it. Among others I installed several Google apps, the google account manager (switch off sync in China as it will draaaain your battery), and MIUI 5.10.16 dev. So far so good.

However, when I tried the camera, the online shots of which were very promising, I was so disappointed I ordered the Nexus 5X straight away. In any circumstance that isn't sunny, the rear-facing camera will perform horribly. What I mean is that, unless you stabilize the phone securely with two hands, any shot in a fluorescent light or otherwise slightly dim environment will result in heavy blur. As if you were shaking the phone while you took the shot. Comparing with the Nexus 5 (2013), where you could take a shot from your wrist while riding a bicycle and still have an acceptable result.

Can anyone else confirm? Do I have the worse of two sensors, is it just the tiny objective, or is it software-related? Or is it just what I should learn to accept from a 1500 RMB phone?

Hello mate,
this is what you should learn from a 1500 RMB phone, camera sux as soon as conditions are not optimum. Tried a lot of apps, but the results is still the same. Some apps will focus better though (lenovo super camera v5 for instance).
Nevertheless, a part from the camera, the phone is way better with CM12.1 than the nexus 5X which handle apps horribly again... Very slow to open and reload apps. Which is kind of a big deal.

These are all shot from the wrist with minimal effort at stabilizing, the way I used to snap pictures with my Nexus 5

Try to take a few indoor shots with a steady hand. It could be that the software uses a quite long shutter time, which results in a blurry shot if the hand isn't steady.

The second step would be: manually set the shutter time according to your preference.

Sure, steadying the phone entirely will work. But that's not really a solution, as you often take a quick snap, the device is light and therefore in almost all situations your hand will be unsteady. It felt like the nexus5 was able to use shorter shutter times in low-light conditions and took steady pictures almost all of the time.

potentially a software problem; after flashing CM Rom the camera improved significantly (also switched from N5 to 4C)

agreed, it got significantly better with the CM rom. Still fairly noisy and a little blurry though. Looks like the camera app (I use Google Camera 4.0) actually takes its time to focus rather than attempting to deliver the quickest shot possible.

Maybe we can have some more samples from another camera app ? We know you have the Sony sensor now, it could be interesting to see if someone has a Samsung one and how is it different in picture quality.

Here are some, as your see low light ones aren't very good and blurred. But even the sunlight ones are a little grainy and not perfectly crisp. Sony sensor.

    my opinion - on daylight its very good - at Evening - Night its "so so" (most photos taken during darker enviroments are not sharp because the camera takes too long to take a photo of my little child - maybe its also because children don't stand still :))....

    But it's way better than the camera of my old Moto G first gen

    In my opinion, all smartphone cameras are bad when it comes to low light (don't know about the newest generation Samsung S6 or Sony Z5, but even my Nikon D80 DSLR isn't fast enough in low light to take sharp pictures of my little daughter without flash). I think the Mi4c camera isn't that bad. It takes better low light pictures than my Sony Z1 "Camera Phone" ;) in general, you always have to fight to take good low light shots with a smartphone. And taking sharp pictures from little kids indoors is one of the hardest fights, even for a DSLR :D

    The pictures here are taken very instantly, perhaps the post processing is somewhat sacrificed? Outdoor or neon lamps lighting gives the best result, I see no noise with it. With fluorescent, however, the noise comes in. I don't have blur problem, though. Same IMX258 sensor.
