I don’t want to transform the input string. A username with uppercase first letter is valid, only thing is the lowercase ones are more common. So I just want to lowercase the first char by default, I don’t want to enforce it to be lowercase.
I’ve tried now autocapitalize=“none”, it did not have any effect for me (tried on Android 7.1) 
Actually, I went on with the idea after autocapitalize; and I found if I set < input type=“email”>, it turns off auto-capitalaze - with a side effect of showing the keyboard for e-mails (eg it has an emphatic ‘@’ char).
Any better idea?
