KKmoon sd27w IP Camera: P2P Connection Instability on Android Devices

Hello, the KKmoon sd27w IP camera, works in the local network via wifi, when trying to connect with the P2P application on Android, the status in a fraction of a second changes from online to connected and it jumps over and over again like crazy. I've tried with different apps and devices and it's still the same. So I exclude hardware, applications and the network. Everything on the PC is working properly is controls and
picture via wifi. You cannot only "enter" the camera with your smartphone. I am asking for help as I can check as a layman.

use the application dedicated to the camera. There will be a problem with other apps.

Thank you, it helped. The proper application is CamHI. I have 4 cameras, each from a different manufacturer, 2 use one application, 2 others. Too bad it's not unified, now I know the app matters. It's not very convenient.
