Prepare your phone for a capture session

The LotJitsu app works without a connection, but only with what it already has on the phone. Run through this list while you still have signal, so a day in a building with no signal doesn't cost you any work.

Before you leave

1. Update the app. If an update is waiting, install it now. An app that is too old shows Update required and can't be used until it is updated, which needs a connection. See Update the LotJitsu app.
2. Log in. Logging in needs a connection. Once you are logged in, the app opens without one.
3. Open each catalog you will work in. Its lot list is saved on the phone when you open it. Do this for every catalog, on every phone you will use.
4. Open each existing lot you will add photos to. A lot that has never been opened on this phone can't take photos offline.
5. Check storage. The app won't save a new photo when the phone has less than 200 MB free. Delete videos or downloads you don't need.
6. Charge up. Start with a full battery and bring a charger or power bank for a long day.
7. Test the camera. Open a catalog, tap Add Lot, and check that the camera opens. Allow camera access if the phone asks. Tap Back to leave without adding anything.
8. Wipe the lens. Fingerprints and dust blur every photo.

Good to know

• New catalogs, folders and lots can all be created offline, so you don't need to set those up in advance.
• If a catalog's platform fields have never loaded on the phone, you see "Fields for platform aren't available offline yet. Connect once to load them." Opening a catalog on that platform once while online fixes it.
• Battery-saving modes can stop the app sending work in the background. Sending is most reliable while LotJitsu is open on the screen.
• Use one account on the phone for the whole session. Logging in as someone else erases everything the previous account had not sent yet.

When you get signal back

1. Connect to Wi-Fi or mobile data.
2. Open LotJitsu and keep it on the screen. Plug the phone in if you can.
3. Pull down on the Catalogs page to start sending straight away.
4. Leave the app open. While it still has work to send, it keeps the screen from locking. When the phone locks on its usual schedule again, the app has sent what it can.

Don't sign out until the app has caught up. Signing out with a connection erases anything not yet sent, after only a couple of seconds.
