Hello,

We have migrated our old telephony system to a new Teams telephony system.

We have bought 50 Samsung Xcover5 smartphones to replace 50 previous DECT phones, that are mostly used in our shopfloor.

Since we have migrated we face issue with call disconnection or call not received etc..

After deep analysis I've found that when the screen is off on these smartphones, we see spikes in the latency, up to 2000ms every 3 or 4 pings, so we suspect the issues is due to that.

We think it's related with WIFI power save on this model, FYI we don't face this issue with a Samsung S20, or even an XCOVER7. Also the Yealink phones, using WIFI dongles, are not showing the same problem.

How can we disable WIFI power save on these XCOVER5, I don't see any setting to do so on Android 14.

This is critical for use, many thanks by advance for your help.
