This app is most useful for devices that don't include this information in the status bar, or that hide it when roaming.
- Due to the way Android works, a non-removable notification must be present along the status bar icon.
- Likewise the icon can not be placed in the right hand side of the status bar.
- In Lollipop and up, the notification will show in the lockscreen. I'm not aware of any way to avoid that.
- This app is expected to work in multi-SIM devices, but (for the time being) only for the primary card.
- Some devices (e.g. Xiaomi/MIUI devices) will display the app's icon instead of the connection type in the status bar. In those devices you'll only be able to see the network type information in the app's notification.
- (Lollipop and lower only) Phone / Device ID & call information: read phone status and identity - This is required to read the network type. This app doesn't use a phone's "identity" for any purpose, but these permissions always go together.
- Other: run at startup - This is required for the notification to load at boot (if you so choose)
