150ms delay on QR decode (iOS)

[Deleplace]

Current behavior:

• Mobile successfully scans (decodes) the QR-code
• Mobile vibrates (short)
• Mobile shows the "next view" (either Success or Uploading)
• Mobile notifies the backend
• Backend notifies the frontend
• Frontend acknowledges and display something (message, or thumb, or resource)

Suggested behavior:

• Mobile successfully scans (decodes) the QR-code
• Mobile notifies the backend
• Mobile pauses for 150ms
• Backend notifies the frontend
• Frontend acknowledges and is ready to display something (message, or thumb, or resource)
• Mobile vibrates (short)
• Mobile shows the "next view" (either Success or Uploading)

Thus, by offsetting the duration of a few network hops, the visual feedback on the target and the haptic feedback on the mobile should happen roughly at the same time, making it feel instant.
