After changing my main deco from x50 to BE65 (Access point mode)

All of my android phones with 433 link speed (WiFi 5) only get like 150-200 mbps average and never exceeded 250-260 mbps from the BE65. Meanwhile my old set up with x50 gives me 300-340 mbps which is maximum speed for those phones and more stable speed as well. Test right next to the Main Deco / Only 5GHZ 160 MHZ enable.

Notebook with WiFi 6 somehow work like they should tho getting around 850 mbps average. Also 400-600 mbps with iPhone Xs from both of BE65 and x50 as main.

Problem seem to occur with those android phone only when connected directly to the main BE65. I am very confused right now. Any thoughts about my problem.
