Hi there! I understand you're having trouble with the mobile check deposit feature of your Bank of America app, specifically it keeps logging you back in when you try to capture a photo of the check. Let’s work through this issue together.

To start, I have a couple of clarifying questions:
1. Have you tried accessing the app using a different internet connection, like switching from Wi-Fi to mobile data or vice versa?
2. Have you attempted to clear the app's cache or reinstall the app altogether?

Here’s a step-by-step guide that might help:

1. Check Your Internet Connection: Ensure that your internet connection is stable. Try switching between Wi-Fi and mobile data to see if the issue persists.

2. Clear App Cache (if applicable):
- Navigate to your device's settings.
- Find "Apps" or "Application Manager."
- Locate the Bank of America app and select it.
- Tap on "Storage" and then "Clear Cache."

3. Restart the App: After clearing the cache, exit the app completely and restart it. This can help refresh the connection to your account.

4. Reinstall the App: If that didn’t work, uninstall the Bank of America app and restart your device. Once it’s back on, download and reinstall the app from your app store.

5. Check the Photo Quality: Sometimes, if the photo you're trying to upload has issues (like being too blurry or poorly lit), it may prevent successful uploads, making the app loop you back to login.

If these steps don’t resolve the issue, it may be worth checking with customer support directly via this link for login issues: Bank of America Login Issues.
