1Password won't run from SD card on Samsung Galaxy J 2017

Hi JFAgm,

I'm sorry to hear you're encountering issues running 1Password for Android from your SD card.

1. Is 1Password specifically designed not to run from external storage on Android, and if so why? And why isn't this documented anywhere?

While 1Password isn't specifically designed to not run from external storage, as you've mentioned you had to enable the option to override the Manifest recommendation for app storage in developer options to get apps to install to SD card, we would be unable to provide support for issues that arise when 1Password for Android is installed via other methods than the standard installation method, which would be to the internal storage of a device.

Depending on the brand/type of SD card and it's specifications, the read/write speed of the card may be too slow to support the read/write operations performed by the 1Password for Android app, especially as these operations would be with encrypted data, which can rely on faster read/write speeds for the app to run optimally.

1. As a retired software engineer, I believe that every crash or freeze is a bug - the result of an improperly handled error somewhere. So, if not running from external storage is intentional, please provide an intelligible error message when the attempt is made

As we wouldn't intentionally be preventing the 1Password for Android app from running on external storage, there may be variables mentioned above such as the write/read speed of the SD card being used or the changes made when the app is installed using the non-standard installation method enabled via developer options that are leading to the issue occurring. Due to this, we wouldn't be able to provide an error message on why the app isn't loading/is freezing. With that said, I could log a feature request with our Product team to see if it would be possible for a check to be implemented in the 1Password for Android app to detect when the app is installed in external storage and to provide a warning that the app may not function as expected or may not work at all when installed outside of internal storage, although I cannot guarantee if/when this will be implemented.

I hope this helps.
