Although mentioned in the update, the camera quality optimization feature is not present in the update of my phoneThe feature is missingThis image is from the Internet, showing the feature. Model Code:SM-G990EZAIPKD
Maybe contacting Jazz could resolve the issue.Some sim cards enable only 3G, but I don't know if there are some that are only 2G.First, check the same sim in a different phone to identify if the issue is in sim or in the phone.
