Settings/Preferences does not get launched

I am trying to launch Settings/Preferences on a real iOS device using Appium 1.6.4-beta and Java client 4.1.2?

I tried giving bundle id = com.apple.Preferences but nothing happens and this is what I see in the logs.
Is this a bug?

[debug] [JSONWP Proxy] Proxying [POST /session] to [POST http://localhost:8100/session] with body: {“desiredCapabilities”:{“bundleId”:“com.apple.Preferences”,“arguments”:[],“environment”:{},“shouldWaitForQuiescence”:true}}

It worked after restarting the device. Weird but glad that it finally worked.

Aah :frowning: It’s not working again. I see the same

Any thoughts please?
