Mobile app

Takes forever to make a mobile picture deposit 😡

Always giving me issues

For some reason it likes to tweak out and not let me log in. But only when it decides it wants too. This has happened to me more than 10 times in the months/years I have had this app. It has made me change my password so many times (when the password is correct) I know for a fact, because I have my password saved for myself to make sure. But it always says “it’s having issues blah blah blah blah” when I need to be able to check my account and what is going on. It has upset me so often, I am so ready to switch banks. Like…seriously. I never had issues when it was Wells Fargo. But you guys bought my bank and now I have issues. Figure it out and stop having issues with the mobile app and logging in when my passwords and everything are correct. I shouldn’t have problems logging in when I need to check my stuff. I have bills and things I need to take care of for my kids. No, I can’t call anyone. It’s 11p.m…fix it 🫠 also, yes. I update the app and everything.

iOS 27

does not open in iOS 27, error on login

App problems at times

I sometimes have problems logging into the app for no apparent reason. I have to close everything out and try several times. Sometimes I can’t get in it at all and have to go to the website. Also face ID will rarely work. But I do like the convenience of being able to submit checks with the camera.

Garbage app does not work

Garbage company, no management at the hedperia branch. I saw an old man say the App does not work and staff kept rolling there eyes and actually said yes it does.
I find the App is pure garbage and foes not work all ghose girls need to be fire 10 years ago. Soooo dumb!

I cannot Zelle

I don’t know this is the right channel, but I’m writing because I am having trouble with Zelle. When i go to Zelle via your app I get this message “this payment functionality is unavailable at this time. Please try again later” . The issue started 2 months ago. I been deleting and reinstalling the app. My iPhone 8 Plus has the iOS 16.7.16 (20H392) version. And your description supports ios 15 and beyond. I hope the developers read this.

Way to buggy

Awful app. Constantly bugs out glitches. Won’t let me in half the time so I have to use their website. It needs fixing asap

White glove service

Great rates!

Would love to see rate you are getting when log in. Great rates so far. Friendly customer service. Would love to see interest rate I am getting in app after log in.

Genuinely the worst bank ever

The app is always crashing and locking me out for days or weeks on end, and whenever I try logging in via browser I’m always told I don’t have an account. It gets to a point guys

Nice bank, nonfunctional app

I haven’t been able to log in via app for AT LEAST 4 months. Prior to that, app would randomly turn off Face ID and require login.

I like the Flagstar Bank, but the lack of investment in their tech - or at least fixing the app since it appears to have broken after the last update (4/2026) is a problem.

Does not Login

The app doesn't work on my IPhone 17. I have tried updating, redownloading, and even asking others for help. Nothing seems to fix the fact that I cannot login at all!

Another outage?

There always seems to be a problem with this app. It’s actually crazy to not give your customers consistent access to view their accounts.

Notes

Note being able to make notes on transfers from account to account makes me want to leave the bank. Why you would take that Way is beyond me. How are we suppse to know what any transfer is for making dozens and dozens of transfers with no notes. Insane.

Great bank

Very professional and friendly and helpful staff. Have been a customer for over 25 years!

Constant

It asks me constantly to review it. I’ve already reviewed it. Quit asking!

Flagstar app

Can’t get into my account for weeks now!!

Constant Bugs and Pain in the Butt

Look, I mostly chose this bank because it's close by and it was once convenient. But now, the app doesn't work, logging on the website doesn't work, and now it's making me run in circles to get anything done. I just want to deposit a check.

GLITCHY

haven’t had luck logging in for months.

App Doesn’t Work

It used to work, but over past month it has stopped working on both my iPad and iPhone 16. I get an error message every time I try to login. Scared me, but I was able to use the website to login, and see that there were no account issues, so just appears to be an issue with the app.
