App showing white blank screen when quitting app with back button after open push notification

After launching app from tapping on push notification, app is showing white blank screen when quit app with hardware back button. Logged react navigation stack but showing only 1 route in the stack.
I've tried to override the back function by using BackHandler.exitApp() but getting white screen as well. Same goes to the launchMode in AndroidManifest.xml. Tried all possible types but still getting same behaviour. When launch app normally, this issue doesn't happen. Any idea?
Launch normally:
Launch -> Go to MainScreen -> Press back button -> Quit app
Launch from push notification:
Launch -> Go to MainScreen -> Press back button -> Show white screen -> Press back button -> Quit app

Update:
So I tried to remove the myapp intent-filter, change to other launchMode but still returned white screen.
Checked out the adb logcat and notice that OpenNotificationActivity is attached before MainActivity. Suspecting this was the cause but still not sure how to disable/bypass the notification activity directly to main
Tried adding android:noHistory="true" to MainActivity and error still persist. Added logcat for reference.

I think there are two scenarios in which this can happen
the MainScreen is not defined as lunchable activity in androidManifest file (so check that out)
react native is adding an other activity to open your MainScreen
anyways I think the best way is to close the app yourself when user presses the backButton in android
you can use this:
import React, { BackHandler } from 'react-native';
BackHandler.exitApp();
this is for android only
if this didn't help please share your androidManifest file here because I am sure the problem is there somewhere
EDIT
based on comments I understand this is happening because
it seems to be causing from b8ne/react-native-pusher-push-notifications library. I noticed that OpenNotificationActivity is attached before MainActivity. Hence when first backPress is triggered, it's destroying MainActivity leaving white screen from OpenNotificationActivity
so please add noHistory attribute to your MainActivity in your AndroidManifest file for more information please take a look at the no history flag docs

The problem is that it works on my Samsung J3 (2016), but I don't know why it doesn't on my new Samsung M11. Has it something to do with Android versions? I have already returned a Realme C3 that was having same issues because I thought it was due to Mediatek SOC.

Solved. I had to add FINE_LOCATION to the manifest and:
Manually give location permissions in Settings.
or
Make a popup that asks for location permissions the first time the user launch the app.

Closing cover produces a Re-layout

I have some problems with this log. When I close the cover of my phone it says this and my activity goes to next one when this should not happen. Is it possible to avoid this happening?? Avoid Relayout or focus changing??
It doesn't happen when in a Second phone with PIN number. (So i need to put the pin to unlock the phone).
With no PIN so, phone is not locked, just closed the cover. When I open again and the activity restart, the activity had finished and went to next one.
With the second phone, with PIN, when I close I have to put the PIN to enter again and in this case, the activity went in the normal way.

Android Bluetooth startDiscovery not working

I am trying to learn how to use Bluetooth in android. However, I've already bumped into an issue to which I cannot seem to find the answer. When I am calling .startDiscovery() on the Bluetooth adapter it returns false, meaning that it failed. I am not doing anything strange, I get the bluetoothAdapter using BluetoothAdapter.getDefaultAdapter() and then call .startDiscovery() on it.
I am trying to do this from within a fragment.
ACCESS_FINE_LOCATION, BLUETOOTH_ADMIN & BLUETOOTH are all in the manifest
Please let me know if I need to provide some additional information!

After a long search, I finally found the answer. Even though the ACCESS_FINE_LOCATION permission was in my manifest I still needed to 'manually' ask for the permission. Which I did in the following way:
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
Log.i("info", "No fine location permissions")
ActivityCompat.requestPermissions(this,
arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
1)
}
after executing this piece of code, and thus getting the right permission to enable discovery my problem was solved!

the same problem happened in the Android part of my Visual Studio 2019 Xamarin Project, and the C# code is a little bit different:
protected override void OnCreate (Bundle bundle)
{
base.OnCreate(bundle);
global::Xamarin.Forms.Forms.Init(this, bundle);
this.ActionBar.SetIcon(Android.Resource.Color.Transparent);
LoadApplication(new App());
GetAccessFineLocationPermission();
}
private void GetAccessFineLocationPermission()
{
if (ContextCompat.CheckSelfPermission(this,Manifest.Permission.AccessFineLocation)!=Permission.Granted)
{
ActivityCompat.RequestPermissions(this, new string[] { Manifest.Permission.AccessFineLocation},1);
}
}

Android WebView unresponsive after pressing Enter using last visible input

I have simple Android app which is just a WebView running a web application.
If I am using inputs and press enter on the last visible input, the keyboard goes away (which is fine), but I lose all ability to interact with the web application running in the WebView. I can still see the app functioning. Pressing back key instead of enter causes keyboard to go away and I have no problem.
Any idea whats happening and how I can get this to stop?
I have tried intercepting focus changes and requesting focus on the web view, but it seems the web view itself is never losing focus. I've also tried setting an interval to refocus the web apps document.body but it had no effect.
Code:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
tools:context="com.particlesandbox.Play">
<WebView
android:id="#+id/view"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_play);
mWebView = (WebView) findViewById(R.id.view);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.requestFocus(View.FOCUS_DOWN);
mWebView.loadUrl("file:///android_asset/www/index.html");
}
