Same goes with Apple and Samsung/the rest of the phone industry, apple often pretends they are the only company in the world, often comparing to themselves and not competition. Samsung on the other hand has made entire series on bashing apple

I wouldn’t say I guessed, I looked up on google and gave a source, both things I referenced talked about acid, either from the apple or reflux. And it’s not like my comment was rude, blunt maybe, but not rude

The first step is google, second or third is ask reddit, the question has already been asked here too.

Google says it’s left over acidity from the apple that goes from your teeth to your tongue. Health tap says reflux so the answer is probably acidity. Also this was an easy google search, not an elif question.

SA?
