Mobile scanner shows white at first

đź’¬ Mobile

  1. My goal: find why it shows white screen when first openning
  2. Issue: when I first open the scanner on my mobile app it only shows white screen and the “X”
  3. Steps I've taken to troubleshoot: everytime I restart my app when I first open the scanner in my app it only shows a white screen with the “X” at the bottom app. What I found as a turnaround is to open the “google lens” app and then go back to my retool mobile app and then it will work.
  4. Additional info: (Cloud or Self-hosted, Screenshots): using cloud version

Not sure if this link will work, but here is the link of a video to better explain

Hey @MRConcept - thanks for the update and screen recording. We've been working on an updated version of the scanner component that may provide a better experience. It's technically not public yet, but I can enable it for your org if you're interested. :+1:

I am getting pretty much the same issue when trying to get a picture only difference with the picture is I can see a text on the white screen “requesting camera permission” maybe same issue ? But if you want to try with me yes I am willing to test :slight_smile:

Hi Darren, thanks for the follow up finally had the chance to update one of the scanner in one app. Conclusion is it seems to solve the “white screen” issue. One thing is it shows at “scannerV1” not “scannerV2” but the icon is showing ScannerV2. Also the “single scan” option is not showing and if I try the event handler on capture to navigate back it does not work. Outside of that it looks nice :slight_smile: hihi

HI,

sorry for the delay. Issue seems the same. The issue is everytime I close the app (swipe it to close) I need to “rehauthorize” to the camera. What I found out is I can simply get out the retool app (without closing it) then reopen the retool app and it works. It is still annoying though.

Hey @MRConcept - there have been a few updates to the mobile app and camera integration since we last talked. Are you having any challenges with the scanner component?

I am still experiencing the exact same issue as wether I want to scan or take a picture it always block me as requesting the camera authorisation so I need to swipe the app down then reopen it so it works.

Are you accessing the app via the web or native Retool app? I've seen the behavior you're describing in the former, but not the latter.

Via the native retool app 3.362.0 version 3535
