It was the first time I yielded to the temptation to take pictures with my phone (addicted to photos, I always balladais with my camera, but older phones do not give me satisfaction with the quality of shots). I'm not disappointed at all: good rendering even with lights very average and yesterday also good photos at a concert, which is however not the optimum conditions in terms of brightness.
For the phone, nothing to say that phone, obviously.
ATTENTION, it runs on Windows Phone, which can be troubling for fans of Android. But you get used quickly and in my case, I finally happier with WP8.
One caveat: When did a lot of photos, the phone memory saturates slowly (as if each photo left a "trace" in memory, even after being cleared on a device that offers 14Go memory, I. after 2 years was left with only 2.5GB available. The rest is absorbed by the unit called "other memory" it is impossible to "purge" except by the complete reset of the device (imposing then reinstall after all)
But no doubt that today, few people still use their smartphone over 2 years, so all is well!
