As Sherlock Holmes might say to Dr Watson... "
The explanation is elementary", to your problem.
Here are the facts...
1. Your Product code is
SM-N915FZWYXEF
2. The, "
XEF", part of the Product code tells me that the phone is running the stock Samsung firmware for the Black Edition of the model,
N915FY, on the firmware for
France. The firmware is the old, November 2014 release on Android 4.4.4, I believe.
3. Your, "
Version", details are,
CSC: N915FOJV1AOA1 tells me that someone, possibly the original vendor, has flashed the
Middle East language pack,
OJV for the
N915F model to the phone. Either that or a highly customised firmware that incorporates elements of both the
N915FY and the
N915F. This is because the
N915FY model was only ever marketed in Europe and never intended for the Middle East. Therefore, this is the only way to get the Middle East language packs on to a European model
4. Your phone will not update because it is the French Black Edition model,
N915FY, that is partially running firmware for the
N915F model for the Middle East.
You now have 3 choices...
1. For the phone to update automatically in future, you will need to flash, via Odin, the stock Samsung French, Black Edition firmware for the
N915FY that matches you phone. This will not have a Middle East language pack.
2. You can update as above and then download the latest Middle East language pack, (if you can find it), for the
N915F and flash it to your phone.
3. You can leave the phone as it is.
This type of flashing by unscrupulous vendors, particularly in the Middle and Far East, is well known as it allows them to sell phones that are not intended for those regions, (the grey market), and which they may have picked up cheaply. Personally, unless you are a competent and qualified Android flasher, I would leave the phone as it is as any attempts to change it could render it unusable for you.
