One Yealink SIP T48S Phone was sent from our customer to our technical service because it was running slow.

We updated the product to the latest firmware and did a factory reset. But it still reacts very slowly to screen operations. In general, switching between menus is slow.

When I enter the web interface of the device, I do not feel any slowness.
I opened Syslog and watched the device for a while, and I can't see any abnormal processing intensity in Syslog.

Has anyone solved a similar problem?
