[Samsung Galaxy S7 Guides, News, & Discussion] sprog123:
Creating a dedicated thread to track this issue, since it seems clear it is a hardware problem. Someone mentioned Samsung incorrectly set the focus to infinity, which for a front-facing camera with f/1.7 lens is just absurd. The S6 was set to something more reasonable like 40cm. With more information from everyone, we can get a better idea of the scope and affected ranges. Please post if your front camera is blurry or not, model, build date/location, HW rev, and FW version. The first two can be found on the sticker on the box. The FW version can be found by entering *#34971539# into the dialer and picking cam FW check. So far, three FW versions seem to be out there, ending in xxLLxxCM, xxQLxxCM, and xxLLxxPM. There are reports all seem to have out of focus front facing cameras, but lately the xxLLxxPM seems to be sharper.

You can also enter *#12580*369# into the dialer to see the HW rev and "RF cal" date if you don't have your box sticker anymore. Not sure how to find out the location of manufacture though. In my case, the RF cal date was two weeks before the build date on the box sticker.

The latest update of AIDA64 also reports the focus modes for the cameras. It also appears that there are two distinct camera ID numbers, SLSI_5K4E6XX with only fixed focus mode and SLSI_S5K4E6_FIMC_IS with both fixed and infinity focus modes. The 4E6_FIMC_IS seems to be sharper and correlated to HW Rev MP 0.700 or later with FW version xxLLxxPM (with one report of a very early HW REV0.2 also having the same camera).

To try to normalize and quantify subjective "blurriness," please post a photo if you can, in good lighting with all beauty modes disabled/set to 0 such than any blurriness from noise reduction is reduced and any smoothing from beauty mode is eliminated. Photo should be taken at half to full arms length with clear separation between foreground subject and background. Both foreground and background subjects should have fine detail and high edge contrast.
