Samsung send the updates out in waves dependant on region and phone eligibility and serial and build number @Somie  

If a phone has been imported from one country to another then this can occasionally have an impact on the update timeframe. 

If you have a Samsung Experience Store or Samsung Service Centre local then they maybe able to assist. 

If nkt then it would be a case of periodically checking your phone's software update section. 

Ensure there's enough internal storage space for the update. 

I hope you receive the update as soon as.
