You sign the back of your check with "For Mobile Deposit Only at Bank of America", tap "Deposit Checks" on the app, select your checking account, enter the dollar amount, and tap "Front of Check"—only to stare at a completely black screen, a frozen camera viewfinder, or an error stating "Camera not available. Please try again later."
You can't take a picture of your check, and you can't deposit your money.
Do not worry: your phone's camera hardware is not broken, and your check is not invalid. This is a recognized software handshake failure between the Bank of America app's proprietary image capture engine and your smartphone's operating system camera subsystem.
Here is how to resolve the black screen bug and successfully deposit your check.
Why Does the Mobile Deposit Camera Go Black?
The mobile check deposit camera displays a black screen when the Bank of America app fails to acquire an active hardware lock on your phone's camera sensor. This occurs due to corrupted OS camera permissions, background camera access conflicts by other apps, or an ultra-wide lens switching glitch on modern multi-lens smartphones.
| Hardware / OS Factor | Technical Cause | Primary Fix |
|---|---|---|
| Operating System Permission Glitch | Camera permission set to "Ask Every Time" instead of "While Using App" | Re-grant camera permissions in OS settings |
| Background Camera Lock | Another app (Instagram, WhatsApp, Zoom) left camera sensor in open state | Force close all background apps |
| Multi-Lens Telephoto Confusion | App defaults to telephoto/macro lens instead of primary optical sensor | Adjust distance; restart camera module |
| In-App Image Capture Cache Lock | Temporary check image cache corrupted in app storage | Clear app storage / Offload app |
5 Steps to Fix the Camera Black Screen Error
Follow these verified steps in order:
1. Cycle Camera Permissions in OS Settings
Do not rely on the in-app permission prompt. Manually re-granting hardware access resets the camera HAL (Hardware Abstraction Layer):
- On iPhone (iOS):
- Open Settings > scroll down to Bank of America.
- Toggle the Camera switch OFF. Wait 5 seconds.
- Toggle the Camera switch back ON.
- Force-close the Bank of America app and re-open it.
- On Android:
- Open Settings > Apps > Bank of America > Permissions.
- Tap Camera > select Don't Allow.
- Re-select Allow only while using the app.
- Ensure Use precise camera access is enabled.
2. Force Close All Background Apps Using the Camera Sensor
Modern mobile operating systems prohibit two apps from accessing the camera simultaneously. If an app running in your background holds an open camera stream:
- Swipe up to access your App Switcher / Recent Apps tray.
- Swipe away and force close all apps—especially social media apps (Snapchat, Instagram, TikTok) and communication tools (FaceTime, Zoom, WhatsApp).
- Re-open Bank of America and retry the check capture.

3. Clear App Cache and Stored Media Fragments (Android)
If a previous deposit crashed halfway through image processing, a corrupt image fragment in your cache will prevent the camera viewfinder from initializing:
- Go to Settings > Apps > Bank of America.
- Tap Storage & cache.
- Tap Clear Cache.
- Restart your phone to flush the system media server memory.
4. Adjust Lighting & Surface to Prevent Auto-Focus Freeze
Bank of America's automated check reader uses edge-detection algorithms that run live inside the camera viewfinder:
- If you place a white check on a white countertop or reflective glass table, the contrast detection loop can freeze the camera feed.
- Place the check on a dark, matte, non-reflective background (such as a dark wooden desk or black folder) in a well-lit room.
- Hold the phone completely parallel to the check, about 8 to 12 inches away. The app will automatically detect the four corners and snap the photo without you pressing a shutter button.
5. Offload and Reinstall the App (iPhone / iOS)
For iOS users, offloading clears the internal WebKit media frameworks without wiping your login credentials:
- Open Settings > General > iPhone Storage.
- Tap Bank of America.
- Tap Offload App and confirm.
- Once completed, tap Reinstall App.
- Launch the app, log in, and grant camera permissions when prompted.
Frequently Asked Questions (FAQ)
Can I deposit a check by uploading a photo from my phone's photo gallery? No. For fraud prevention and anti-tamper security reasons, Bank of America does not allow uploading pre-saved images from your photo library. All checks must be photographed live inside the secure app container.
What should I do if the camera still won't work and I need my money today? If the camera remains black, you have two instant alternatives:
- Visit a Bank of America ATM: You can deposit physical checks with zero fee at any Bank of America ATM without needing an envelope. Funds follow standard mobile deposit availability timelines.
- Visit a Financial Center: A teller can scan your check at the counter and provide an immediate printed receipt showing available balance release schedules.
What is the exact endorsement requirement for Bank of America mobile deposits? You must sign your legal name on the back endorsement line and write legibly directly below: "For Mobile Deposit Only at Bank of America" (or check the pre-printed mobile deposit box if present on the check). Failure to include this exact wording will cause the automated system to reject the check within 24 hours.
