launch time is long only on iphone11 pro, expo SDK35, iOS13.3.1, expo kit.


I am about to deploy my app to app store.
I have tested the app on multiple iOS devices.
On most of them, splash screen disappears within 3 seconds, then the app launches.
But on iphone11 pro, it takes more than 10 seconds before splash screen disappear.

I want to make app’s launch time shorter on all devices.
thank you.


Does it do this on multiple iphone11 pro devices? Or just one in particular?

Are you perhaps able to route the traffic from the phone(s) with the problem through a machine running Wireshark or some other packer sniffer to see if a certain network request is taking a long time? This might also be done with port mirroring on a switch instead of routing traffic through the sniffer if you have a switch that supports port mirroring.
