    Does the camera work in other apps? (If not, it's a bad camera module.)

    Did you install the Walmart app using the S7? (Using a different device to download it can give you the wrong version.)

    Are you scanning in a bright light, and allowing the full barcode or QR code to be seen? (If yes, try typing the code in - it works that way too.)

    Yes the camera woks very well with the others scanner apps.
    The walmart app I downloaded from play store on my s7, and I try uninstalling the app but when download again it's the same, not working.
    When I try to scan, I can't see nothing in the screen, normally in the tablet and my old phone, s5 mini, I I cat see the Qr code, like a camera, o see the table, everything, but in s7 nothing!

    Possibly the app isn't updated to the latest version of Android, or to the S7. Tap where it says "Type Receipt Info" and type it in.

    The same thing is happening with my samsung galaxy S5 so i dont believe it to be an update issue.... i didnt have this issue before but started doing this about 3 months ago . I type them in when using saving catcher but prevents me from using walmart pay altogether funny thing is that any other qr scanner i download functions perfectly... camera works perfectly without any issues it is just that particular app it dislikes so i believe this is a walmart app issue for the majority of the samsung line?

    Mine is doing the exact same thing! It worked for months and then one day, the black screen. I've checked all my settings to make sure it has permission to use the camera and I have uninstalled/installed several times. I can't scan my savings catcher receipts or scan a item for the price. It's just so aggravating for it to malfunction because if I want to look up a price I have to either manually find it on the site or find a in store scanner. Neither of which is great when you've got a cranky 3 year old with you, lol. I have had updates to my phone so it's running the latest system, but it may have been one of those updates that caused it to not work. One of you guys that are way smarter in tech, please help me fix this!

    I've been scanning receipts for over a year now and never had a problems using Note 4, Note 5, Nexus 6 and 3 different iPhones.

    However about a week ago it started doing this on my AT&T Note 5. Black screen. Won't do anything Wiped data and reinstalled several times with no luck.

    I recently resolved this problem on my wife's LG Ultimate 2 with Kit Kat 4.4.2.
    Since the phone was rooted it is running Xposed. So I downloaded an Xposed module called "App Settings". After activating the module and rebooting, I opened the app and scrolled down to "Walmart" and tapped on it. I then activated the toggle on the top, pushed the "permissions" button, and then switched on the toggle that said "Revoke Permissions". I then scrolled down to "android.permission.CAMERA (take pictures and videos)" and tapped on it. I hit "ok" and then tapped the save button up top.
    After this, I opened the Walmart app and it said that the walmart app had been denied access to the camera. I then went back into the "App Settings" module and repeated the steps above to turn "android.permission.CAMERA (take pictures and videos)" back on! After saving, I reopened the Walmart app and the savings catcher scanner worked once again and so did the bar code scanner in the app!

    I have an Edge 7 and the same thing happened to me also. I did similar thing as previous replier who's wife had the LG phone....First went to app permissions and turned off walmart app permission to use the camera. Then when I went back in walmart pay , it said there was no access to camera. Went back to app settings simply clicked allow permission to use camera, clicked on it and now it works again!

    My S7 just suddenly became incompatible with the Walmart app. This is ridiculous

    If the app developer takes certain shortcuts, a new version of Android, or even a security update, can break the app, Then you have to wait for an update to the app.

    I saw that the Walmart app got installed to the SD card. After moving it back to device storage, the scanner camera worked again.

    Same thing started today on my Samsung Galaxy S7. Can't scan a barcode for a price check, and can't scan the code to activate Walmart Pay. Running latest available Android OS v7.0 Kernel 3.18.31 (Mon, 8 Jan 2018). Running latest available Walmart App, v18.3.1. Restarting the phone did not fix it. Camera app works fine. Mon, 12 Mar 2018, 2:15 pm EDT (UTC -0400)

    UPDATE: Mon, 12 Mar 2018, 5:16 pm EDT. The app has started working again on my phone. No indication that the app itself updated, but now when I request a barcode scan or setup to scan the Walmart Pay QR code, I see whatever the camera is pointing at again, and not just a black screen.

    can't scan the code to activate Walmart Pay
    That seems to be a Walmart problem (not with the app, with Walmart itself). A few of the registers in my supercenter work fine with Walmart Pay, a few don't work at all and some work sometimes and don't at others. (Or it's an operator error - when you're scanning the barcode [and you have to be connected to the store's wifi] they have to press some button or other on the register [I never asked, but I know they get some prompt and have to press something]. I've given up on it until they get it fixed - or I use the self checkout, which always works - if the right associate is there [they have to transfer the sale to the main register to complete the sale].)

    I don't think that is the same issue. I get a screen that looks like the one I expect, but the background just stays black, instead of showing the product barcode, or the Walmart Pay QR code on the register.

    I have a Google Pixel 2 XL and Walmart Pay does not work either. neither does the bar code scanner. it worked seamlessly with my Samsung Galaxy Note 5, but not my Pixel 2XL😫. To clarify, it opens the camera and I can see the code, it just doesn't read it. Both QR and Bar Codes aren't being read.

    This may just be a fluke, but it just worked for my Samsung Galaxy Sky. I did the partition wipe as instructed for the Galaxy S6. Turned off my phone and turned it back on. I uninstalled the Walmart app and reinstalled it. My phone now scans the savings catcher!
