What are some of the problems you are experiencing? It will be quite difficult for FTers to help you unless you provide some more specifics. And also make sure the app is compatible with your version of Android. The current app requires Android 4.0+ to work. I have seen numerous people on here who have been using the app for years only to find out the app no longer works with their device.
I try to log in on the login page with exact info I use on delta.com and the message I get is sorry that didn't work please enter valid long in credentials. ....they are the valid long in credentials and of course delta it is zero and I mean zero help

I was having login problems a few months ago. For well over a month I wasn't able to login with droid smartphone. I kept getting a message that said something "opps that didn't go too well please try again". I de-installed Delta app and re-installed again and same problem. I gave up. Then a few days ago, after not trying for several weeks, I tried again and I was able to login with no problem. I think the problem is with Delta's app.

Op: You haven't identified a specific device, Delta app release, nor version of Android you're using. There certainly are Android users who have used the app successfully within the last three months - me included.

Sometimes if you have old software on the device, it can be a mistake to attempt to update an app without first checking that the new version is compatible with your system. If it's not broken, don't fix it without first checking carefully that this is what you want to do.

I have a Galaxy 5S and the app is working fine. I wanted to suggest typing in your information slowly and waiting a few seconds before hitting "log in". On several different apps I've found this to be helpful. Sometimes the phone/app lags and when you hit "log in" the information isn't finished computing (for lack of a better word).
