为什么我的应用程序在我的 android 仿真器上运行良好，但在我的真实 android 设备上运行不正常

Question

My app is working fine on my android emulator but its not working fine on my real android device my i am using react native & nodejs if anyone can has faced this same problem pls help me

NOTE

• MY REAL PHONE resolution & screen size ARE SAME WITH MY android emulator BOTH ARE SAME
• MY ANDRIOD EMULTOR API IS 30

ISSUE THAT I CAN SEE IN MY REAL ANDRIOD PHONE

• Some text are going their on the wrong position
• Some text are not even seeing to me but their onpress event is working
• my backend is not connecting with my app. I mean socketio is not connecting in my real phone but its connecting in my emulator i am using http://10.0.2.2:3000 in my base url to connect my app with backend i can't use localhost because emulator is not supporting it So the question is what url should i use to connect to my app with backend while using my real phone?

WHAT I HAVE TRIED

• Deleted my app from my real phone than run npm start & npx react-native run-android

• i have added android:usesCleartextTraffic="true" in android\app\src\main\AndroidManifest.xml

• i have also done cd android./gradlew clean cd.. and than npx react-native run-android

• NONE OF THESE SOLUTIONS WORKS IN MY CASE

HOW IT LOOK LIKE IN MY ANDRIOD EMULTOR ITS LOOKING FINE AND THIS ONLY I WANT

BUT HOW IT IS LOOKING IN MY REAL PHONE
