Help Samsung Note 8 (sm-n950n) not turning on, and not charging after trying update the firmware

svim
With Samsung devices, the recommended way to flash firmware is with the Odin or the Heimdall utility. If the first time failed, try flashing it again. If that works out then you should be good to go, but if it fails, come back here and post the text of the entire resulting log results.
Is your friend sure they used the correctly matching ROM? ROMs are very model specific so flashing the incorrect version will often result in a boot loop or a complete fail. Flash using the correct ROM should fix that.

How to solve slow Bluetooth RFCOMM rates on current tablets

F
Android Slow Bluetooth RFCOMM Transfer Rate with RN4678 - Stack Overflow

It seems like almost all newer tablets have this problem. We previously used the Lenovo M10 Plus FHD 2nd Gen which did not have this problem. We are trying to switch to the Samsung Galaxy Tab A8. I don't believe this is due to interference despite the answers on Stack Overflow (considering the old Lenovo tablet worked fine). I tried things like adjusting the buffer size and changing the interval of the keep-alive command, but it didn't have much of an effect.

BTW, this isn't file transferring, but reading live data from two load cells connected to a board via Bluetooth (Classic, not BLE).

MKV player

Y
Hello. Very new to android. Was hoping you guys could help me find a good player. I have tried the MX player and VLC player. MX has an overall better quality picture and brightness while VLC has better volume. The MX player sounded surprisingly low with my UE6000 on full volume. Any other recommendations besides these?

Webview Example

saramarz
Here is a simple example of how to use a WebView in an Android app:

Code: 
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    private WebView webView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        webView = findViewById(R.id.webview);
        webView.setWebViewClient(new WebViewClient());
        webView.loadUrl("https://www.example.com");
    }

    @Override
    public void onBackPressed() {
        if (webView.canGoBack()) {
            webView.goBack();
        } else {
            super.onBackPressed();
        }
    }
}

You will need to add the INTERNET permission to your app's manifest file in order to use a WebView. To do this, add the following line to your AndroidManifest.xml file:

Code: 
<uses-permission android:name="android.permission.INTERNET"/>

You will also need to add the WebView element to your layout file. For example, you could add the following to your activity_main.xml layout file:

Code: 
<WebView
    android:id="@+id/webview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

Cannot rebuild after changing targetSdkVersion

Many thanks for your helpful response. After much experimentation, I discovered a message suggesting there was an Android Gradle Plugin update avaiable (I thought I'd done that, but maybe not). After upgrading to APG 4.2.2, I was able to get my project to build (after fixing a couple of other minor errors on the way).
I now have a load of "deprecated" messages but I can look into those in due course.
Thanks again for your help.

Suddenly lost all mobile signal.

This might not be relevant but your phone apparently does not include support for 5G cellular connectivity:
https://www.gsmarena.com/samsung_galaxy_s10e-9537.php
In the Settings menu, try disabling 5G so that forces your phone to only work with 4G/LTE again and see if that makes a difference.

(Keep in mind that 5G support in any smartphone involves a cellular radio chip that's typically soldered onto the phone's logic board, it's not something that can added in something like a software or even a new SIM card. It's a hardware matter, not software. So eventually, you do need give more serious thought to upgrading to a newer phone. Your S10e is coming up on four years old so it's still quite usable but increasingly out-of-date.)

Android Studio won't run apps due to unsigned driver

M
Thanks for the suggestions; however, as I have an AMD CPU, presumably Intel HAXM is not going to work? and as I am running Windows 8.1, the instructions about Windows 10 do not match my system.

I lodged a bug report with Google a few days ago; they said they have not tested Android Studio on Windows 8.1 for a while (!) and would try to reproduce the issue there. https://issuetracker.google.com/issues/264616265

In the meantime I am using a real device to test via a USB connection; I also have BlueStacks installed but that is painfully slow.

Android to Android - Transfer Absolutely Everything!?

M
Sue Anderson said:
Got myself in a right muddle with my new phone which is a Google Pixel 7 Pro. I thought I had transferred everything from my old Huawei P30 Pro, but it seems I haven't. I've now taken my new phone back to factory to have another go.
Is there any way I can transfer absolutely everything, including ALL apps (and be logged in to everything) or am I asking too much? There's so many suggestions when I Google this that I don't know which way to turn.
Just want to be using my new phone as much as I can like it's the old one.... but better.
Any help would be so very much appreciated.

You can transfer all the data, but it is impossible to transfer all the apps and be logged in to everything.
