When a native uses “however” he’s offering an alternative viewpoint. Or offering a different conclusion. Although use, would have to see it in context. ...It can have many uses. The word “despite” or “ in spite of” would be used instead of. Although can be used in the middle of a sentence not just the beginning.

although = despite the fact that, or despite being: He decided to go, although he told me several times that he really didn't want to. Although it was raining, I decided to take a walk in the park. However - can also mean "despite this" but used in a different way. I like cars. However, I do not have one because finding parking is impossible in my city. The same sentiment with "although" would be: Although I lke cars, I don't have one because finding parking..... "However" has other meanings as well.
