"Some reddit users claim that resetting their settings (Settings --> General ---> Reset --> Reset All Settings) fixed all of the app issues, while others have restored their devices and set it up as new to solve the problem. Others have backed up and restored and had better results."
is it possible to downgrade to 10.3 ? I thought you can't do that anymore once you upgrade. I upgraded my old iPad to 10 and the experience is horrible. I wanted to downgrade back to iOS 9 but I can't find a way to do it.
I can confirm. Tried the same - wipe and reinstall. Phone is slightly better but still lags for Camera, forwarding images to WhatsApp and to open iMessage.
And this when I have yet to restore from iCloud or restore an entire 25GB Music cache!
