Wallpaper issues on Yealink T46s after firmware update

[Tarheels]

I did a update on my 3cx to software 16.0.5.611 and updated the firmware on the Yealink T46s phones to 66.85.0.5. After the updates the wallpaper on the phones have lines thru them. I uploaded a new image but still got the same result. Has anyone else had this issue ?

Is that the default 3cx wallpaper or something else?

It is a custom wallpaper

are you replacing the 3cx image on the server, then reprovsiong or uploading to the phone directly? if replacing the 3cx image, try to upload to the phone to see if that works, your image may need to be redone at the same size and resolution as the 3cx default image

Factory reset the phone and reprovision it. An incompatible wallpaper may freeze the phone in the most extreme of cases.

I would recommend you look at Yealink's technical documents to see what format and size of image to use in order to avoid having the phone misebehaving.
