We are running expo SDK 33.
We are finding that some tablets we put our Expo app on have huge data usages. We are talking a gig a day. They are on all the time, but as we’ve measured our app’s normal network transmissions - it’s only around 80-100 mbs.
Androids data usage monitoring says the usage is from our app, not another one. We’ve turned off OTA updates in the manifest (app.json).
It’s just not scalable to have talbets that, with minimal usage, use a ton of data.
what I’ve done so far
I’m watching wireshark on the tablet, and I see some things that may be either expo or another software running on the machine. I’m seeing:
- graph.facebook.com (our app isn’t integrated with facebook)
- e.crashlytics.com (which we also don’t use)
It’s not on all tablets, and there seems to be no common threads between apps - so is there any way OTA’s are actually being downloaded - or partially downloaded? Or is there anything else within expo that may download, or upload anything? We’re looking for something that one in every few long running app instance may take a ton of over the wire (data/wifi) usage.
Let me know if there is any other info you need.
