I've asked a similar question before without success. I have a user registration service. When login the username is also mapped to a localstorage, which later database rows are connected to. So when I later query rows under that username everything is good. As long as my phone don't make the first letter of my username Uppercase (when login) which then results in nothing found when doing a query (searching rows with that specific username). How do I solve this problem? Please don't direct me to some long documentation as I've read through many of them without finding my answer. Would really appreciate the help! Thanks! A solution would be to make the login case sensitive but I have no idea how to do that either. Again thanks for replies.
