Great app! This is the best barcode scanning app I've found. Additionally, it's free, ad-free, and open source. If you need a good barcode scanner, this is where you should start. Note: almost all of the bad reviews are because of permissions; the app description/FAQ explains why they're required, and the app is open source if you really want to verify it!
Wifi bug on Galaxy S5 and S7 I really found this app useful for a few years now but recently I noticed that there is a bug that causes the WiFi on my phone not to shut down properly when I switch it off. It keeps turning on and shutting off repeatedly which causes a drain on the battery. I uninstall it on both the Galaxy S5 and S7 and the problem stop on both phones.
When it works it's great! Works fine on my phone, with lighted camera. Does nothing on Galaxy Tab 3, tho cameras are otherwise the same. Found a few alternate apps that do not require this specific barcode scanner, so no longer necessary.
The app can only read barcodes when the phone is oriented at landscape mode. If the phone is in the portrait mode, the reading screen remains in landscape mode and I'm unable to read the code (when at the settings menu, the screen follows the phone's orientation, the problem is just when at the scanning mode). I already tried to change the "no automatic rotation" option, but the problem persists. Had the same issue with Moto X 2nd gen (now with Galaxy S7E).
Been using this for years! Free and no ads. Doesn't request a bunch of weird permissions like most other barcode scanners. The only problem I have with it is that you have to dig through the settings to turn the flash on. If there was a quick way to turn it on or off like in the camera app, this would be ideal.
Best bar code, QR code, Matrix code etc. scanner. ZXing team developed the bar code deciding library that is widely used, so why not directly use their own product rather than a 3rd party's?
