Have you tried multiple times to scan? And while connected to the Internet?
Any possibility that there is some security app preventing the download?
There are other apps using the same vision technology that Geooh employs. See if the app below works on your phone
The camera work with this app but when I tap the screen, nothing happen, no recognition
Is there a way I can generate a log file that could help you ?
You mean Geooh or the other app? You can't tap on the other's app's screen for recognition?
Not really... Geooh is using a Google test to check if the detector is available and if not, shows the message... so there would not be a log of anything valuable. Try removing Geooh off the phone, and reinstalling it to see if that changes things. I'll keep researching on my end to see if other developers have experienced something similar.
Can you see about freeing up space on your phone?
You may also try go to Android settings app info, locate Google Play Services, then clear cache for its storage in case something needs to be freed up there.
I greatly appreciate you reaching out to help determine the cause. Too often, someone will just leave a poor rating saying the app doesn't work without giving the developer a chance to resolve the issue or explain why it's happening. It may not be the app's fault, but it gets knocked down regardless.
