How To Fix Samsung Galaxy A7 “Unfortunately, Camera Has Stopped” Error (2026 Guide)

The “Unfortunately, Camera has stopped” error on the Samsung Galaxy A7 means the stock camera app has crashed. In most cases, corrupted app cache or a conflicting third-party camera app is to blame — not broken hardware. This guide walks you through every fix, starting with the quickest solutions and working toward more involved steps.

Applies to: Samsung Galaxy A7 (2017, SM-A720F) and Galaxy A7 (2018, SM-A750F/FN). Some menu paths may vary slightly between One UI and the older Samsung Experience interface.

Quick Diagnostic: Software vs. Hardware

Before you start troubleshooting, it helps to narrow down the cause. Use this table to identify which type of problem you’re likely dealing with:

Symptom	Likely Cause	Start At
Error pops up randomly, camera worked fine yesterday	Corrupted cache or recent app conflict	Fix 1
Error appeared right after a system update	Outdated or corrupt system cache	Fix 4
Error only happens when using a specific camera mode (e.g., panorama, video)	Camera app data corruption	Fix 2
Camera shows black screen, then crashes	Possible hardware sensor failure	Fix 6, then Fix 7
Error started after installing a new app	Third-party app conflict	Fix 3
Clicking or grinding noise from camera module	Hardware failure — camera module damaged	Fix 8
Both front and rear cameras crash immediately	Firmware or sensor-level issue	Fix 5, then Fix 7

Fix 1: Force Restart Your Galaxy A7

A force restart clears temporary memory without deleting any data. This fixes the error about 30% of the time when it’s caused by a one-time software glitch.

For Galaxy A7 (2017) with physical Home button:
Press and hold the Power key + Volume Down key together for 10–15 seconds until the phone vibrates and restarts.

For Galaxy A7 (2018) without Home button:
Press and hold the Power key + Volume Down key together for 10–15 seconds until the Samsung logo appears.

Open the Camera app after the restart. If the error returns, move to Fix 2.

Fix 2: Clear Camera App Cache and Data

Corrupted cache is the single most common cause of this error. Clearing it forces the camera app to rebuild its temporary files from scratch.

Go to Settings → Apps (or Application Manager on older firmware).
Tap Camera from the app list. If you don’t see it, tap the three-dot menu and select Show system apps.
Tap Storage.
Tap Clear Cache first, then open the camera and test it.
If the error persists, go back and tap Clear Data → confirm with OK.

Clearing data resets all camera settings (grid lines, resolution, timer, etc.) to defaults but does not delete your photos or videos. Those are stored separately in the Gallery/DCIM folder.

e first, then open the camera and test it.

If the error persists, go back and tap Clear Data → confirm with OK.

Clearing data resets all camera settings (grid lines, resolution, timer, etc.) to defaults but does not delete your photos or videos. Those are stored separately in the Gallery/DCIM folder.

Fix 3: Check for Third-Party App Conflicts (Safe Mode)

Third-party camera apps, flashlight apps, and QR code scanners are notorious for locking the camera sensor and causing crashes on the stock Camera app. Safe mode temporarily disables every third-party app so you can isolate the problem.

To enter Safe Mode:

Press and hold the Power button until the power menu appears.
Tap and hold the Power off option until a Safe mode prompt appears.
Tap Safe mode to confirm. The phone will restart with “Safe mode” in the bottom-left corner.
Open the Camera app and test it.

What the results mean:

Camera works in Safe mode: A third-party app is causing the conflict. Restart normally, then uninstall recently installed camera or photo-editing apps one at a time until the error stops. Common culprits include Snapchat, Instagram (camera overlay), third-party flashlight apps, and QR scanners.
Camera still crashes in Safe mode: The problem is with the stock firmware or hardware. Continue to Fix 4.

To exit Safe Mode: Simply restart the phone normally.

Fix 4: Wipe the Cache Partition

The system cache partition stores temporary files used by Android and all pre-installed apps. After a system update, these cached files can become outdated or corrupted, causing app crashes — including the Camera app. Wiping the cache partition is safe: it does not delete personal files, photos, apps, or settings.

For Galaxy A7 (2017):

Turn off the phone completely.
Press and hold Volume Up + Home + Power simultaneously.
Release only the Power key when the Samsung logo appears. Keep holding Volume Up and Home.
When the Android recovery menu appears, release all keys.
Use the Volume Down key to highlight Wipe cache partition.
Press the Power key to select it.
Highlight Yes with Volume Down and press Power to confirm.
When complete, Reboot system now will be highlighted. Press Power to restart.

For Galaxy A7 (2018) — no Home button:

Turn off the phone completely.
Press and hold Volume Up + Bixby/Side key + Power simultaneously.
Release all keys when the Android logo appears.
Follow steps 5–8 above.

Fix 5: Update Your Phone’s Software

Samsung has released multiple patches that specifically address camera stability issues on the Galaxy A7 series. Running outdated firmware is a common cause of persistent camera crashes.

Go to Settings → Software update (or Settings → About phone → Software update on older firmware).
Tap Download and install.
If an update is available, install it and restart the phone.

Note: The Galaxy A7 (2017) received its last major update (Android 9 / One UI 1.0) in 2019. The Galaxy A7 (2018) received Android 10 / One UI 2.0 as its final update. If your phone is already on its latest available version, this step won’t help — move to Fix 6.

Fix 6: Test With a Third-Party Camera App

This step helps determine whether the problem is specific to Samsung’s stock Camera app or whether the camera hardware itself is failing.

Install Open Camera (free, open-source) from the Google Play Store.
Open it and try taking photos and videos with both the front and rear cameras.

What the results mean:

Open Camera works fine: The stock Samsung Camera app has a software bug. A factory reset (Fix 7) should resolve it.
Open Camera also crashes or shows a black screen: The camera sensor or ribbon cable is likely damaged. Skip to Fix 8.

Fix 7: Factory Reset (Last Software Fix)

If every software troubleshooting step above has failed, a factory reset eliminates any remaining firmware corruption. This deletes all data on the phone — apps, accounts, settings, and files stored in internal memory. Back up everything first.

Back up your data before proceeding:

Photos/videos: Copy the DCIM folder to a computer via USB, or back up to Google Photos.
Contacts: Sync to your Google account under Settings → Accounts → Google → Sync Contacts.
Apps and settings: Use Settings → Accounts and backup → Samsung Cloud or Google backup.

To factory reset via Settings (if you can access the phone):

Go to Settings → General management → Reset.
Tap Factory data reset.
Scroll down and tap Reset.
Enter your PIN/pattern and tap Delete all.

To factory reset via Recovery Mode (if the phone is unresponsive):

Turn off the phone.
Galaxy A7 (2017): Press and hold Volume Up + Home + Power.
Galaxy A7 (2018): Press and hold Volume Up + Bixby + Power.
Release keys when the recovery menu appears.
Use Volume Down to highlight Wipe data / factory reset and press Power.
Highlight Yes — delete all user data and press Power.
When done, select Reboot system now.

Important: If you previously signed into a Google account on this device, you’ll need the same Google credentials after the reset to pass Factory Reset Protection (FRP). Make sure you know your Google email and password before proceeding.

Fix 8: When It’s a Hardware Problem

If the camera still crashes after a full factory reset — or if you heard clicking or grinding noises from the camera lens area — the camera sensor module has likely failed. This is especially common on the Galaxy A7 (2017) and A7 (2018) models that are now 7–9 years old, where wear on the ribbon cable or internal flex connector can cause intermittent or total camera failure.

Signs of hardware failure:

Black screen followed by immediate crash, on both front and rear cameras
Visible condensation or fogging behind the camera glass
Clicking or rattling sound when you tap near the camera module
Camera worked briefly after a factory reset but failed again within hours

Your options:

Samsung service center: If you’re outside warranty (which is likely at this point), Samsung charges for camera module replacement. Find a local service center at samsung.com/us/support/service-locations.
Third-party repair shop: An independent repair shop can replace the rear camera module for typically $30–$60 USD. Front camera modules are usually less expensive.
DIY repair: Replacement camera modules for the Galaxy A7 are available on Amazon and iFixit. This is a moderately difficult repair requiring a heat gun, suction cup, and spudger tools. Not recommended unless you have prior phone repair experience.

Samsung Support contact: 1-800-726-7864 (US), available 8 AM–12 AM EST, 7 days a week.

Summary

Most “Unfortunately, Camera has stopped” errors on the Galaxy A7 are caused by corrupted cache or a conflicting third-party app — not hardware failure. Start with a force restart and clearing the camera cache (Fixes 1–2), which resolves the issue for the majority of users. If those don’t work, Safe Mode testing and a cache partition wipe (Fixes 3–4) are the next steps. Reserve the factory reset for cases where nothing else works, and only suspect hardware failure if the error persists after a clean reset.
