It's a good idea today to enable the encryption mechanisms offered on our mobile devices, if not a requirement in enterprise or medical environments.
Is using an Android Wear smartwatch a compromise in our professional or personal data protection?

#Progress  on our display measurement and analysis software.
Colorimeter measurements corrected from spectral readings

Late yesterday night, I completed the math and code to adjust my display high precision colorimeter measurements with spectral readings taken with a spectrophotometer.

During #MWC15 , I was going booth to booth with both a X-Rite I1 Display Pro colorimeter, that's particularly quick and a EFI-ES1000 spectrophotometer (same as a X-Rite i1 Pro), connected alternatively to the tablet running my software.

The spectrophotometer is about 3 times slower, but has the merit to see the light wavelengths intensities while the colorimeter uses some kind of RGB sensor that's able to tell the real colors only if their spectral characteristics match what it has been optimized for.

The correction logic was not implemented until now, so here are graphs from a +HTC One M9 unit, before and after correction.

Not only the spectrophotometer doesn't see the same thing, but these measurement confirm why you've heard reviewers mentioning a ''green tint" on the M9.
It's indeed here, and our eyes are very sensitive to an excess of green. We tend to be less bothered by wrong amounts of red and blue however. The M9 display also has too much blue and not enough red.

Have correction from spectral readings now

There are some good news to come after our first article based on device analysis made during  #MWC15  (2 weeks ago)

The manufacturers didn't stop working then and we have now new elements: an update article is in preparation.

It's unfortunate for everyone who have been really enthusiast reading that +Samsung Mobile Galaxy S6 and Galaxy S6 Edge Fully Support the New Camera2 API

There has been countless articles and discussion over this, as seen on
reddit (247 comments):
AndroidHeadlines (first search result today): 

Galaxy S6 supports some of Camera2 API capabilities, but only few and some are invalid or unfinished.

It doesn't mean the Galaxy S6 won't ever provide a better Camera2 API implementation, but while my methodology can't be infallible I'm fairly certain that the previous reports are invalid and likely due to a software bug.

First article written for is live!

Android Camera2 API promises to revolution digital imaging on smartphones or altogether with advanced capture and processing capabilities that have never been accessible to third party applications before.

Some of what becomes possible is manual controls, computational photography, RAW #DNG  capture, full control over video recording, custom image processing. Limits are few.

Here's an analysis on how much of this new API is supported by the #Lollipop  devices released during #MWC15 , including the highly anticipated Samsung Galaxy S6 and HTC One M9 flagships.
