When selecting "choose image" from gallery in ODK collect, it only sometimes works

Hello,

Welcome to the ODK forum, @Atlin! We're glad you're here. When you get a chance, please Introduce yourself here!. I'd also encourage you to add a real picture as your avatar because it helps build community!

Regarding the issue with selecting image from your phone, despite of Android version the Android OS varies from phone to phone. The problem could be related to that specific model of that device. You can give a try on another device.

Thanks,
Imran
