Can't Change Notification Sound...

the phone is not defective. i would not use any other 3rd party apps that take control of your notifications until you sort out the issue.

i will admit I dont use alexa's sound notifications but i do many other apps and they all have their own sound profile separate from the main "system sound". maybe what you are asking fro the alexa app is not possible in the latest build? you may want to reach out to amazon (there is a good subreddit r/amazondev but dont quote me on the exact spelling) and see if they have changed the app. you seem to know how to change the sound settings and I was able to change the sound settings for one particular routine , but i did not try other settings on that app. it may be just an issue with that app...

Issue with phone storage

We would understand you are skeptical or if you will..hesitant about the factory reset..if that's the venue you don't wanna take..hear me out:

My mom has a J7..and does exactly what yours does..apparently the internal storage fills up too quickly so the phone starts acting up..freezing, lagging, sometimes reboots, asks for apps to be deleted and so on..
So I rescue her day in a way that turns out to be very effective by..

First you don't just simply clear the apps and users data..you actually manually delete it..
You have to go in the folder(any of your choice..the native is good)..then headed to
The Storage..where every single app you've downloaded hoarders bunch of data..then you go to each one and delete all that junk(make sure you save what you wanna save..then get rid of the rest.
Example..Whatsapp, you go inside through the folder..Media..videos..delete them, images..delete them, and so with the rest that are in there..

Then after that..you go to the phone system..look up strange..and then now you can clear the user and app data that is irrelevant.

I hope this helps.

Capturing HTML5 content in a WebView

Greetings,
all the standard techniques for webview screenshot don't work when HTML5 has been rendered. It simply yields a blank page. Render plain HTML and it all works. Documentation for webview doesn't even mention HTML5 or HTML5 canvas, so I'm at a loss for where to look for assistance in this matter.


Thanks

Could not find a native API to snapshot the HTML5, so I solved this issue by using javascript's toDataURL() which converts a canvas to an image.

How to make whatsapp unread message led blinking indicator blink continuously if still unread?

the whatsapp indicator led light blinks for about 30 seconds
I'm completely unaware of any such feature. I wonder if it's a Samsung thing. :thinking:

Anyway, my only thoughts are to check WhatsApp's settings, both in the app and in its System Settings, for a way to extend the time period. Also, see if it has a 'reminder' setting.

I hope someone who actually has the same feature will chime in with better advice!

No static field INSTANCE of type Lorg/apache/http/message/BasicLineFormatter

Welcome to Android Forums, Andrija032!
When I tried to sent image on server, I take this error - No static field INSTANCE of type Lorg/apache/http/message/BasicLineFormatter. Can someone help me with this error. Thanks for all.
You're developing an app, correct? You'll get the best help if you post on our Android Development board, where fellow developers hang out. :)

use app on lock screen without unlocking?

https://www.androidauthority.com/best-android-lock-screen-apps-lock-screen-replacement-apps-565514/

Here’s the thing, folks. Google locked down a lot of your lock screen’s functionality over the years with newer versions of Android. Third party replacements don’t have the power they once did and you no longer have neat things like lock screen widgets (and, by extension, DashClock Widget and similar apps). The stock lock screen can show you notifications, keep out intruders, and always be on if you need it to. Unfortunately, with the lock screen minimized as much as it has been, that’s about all you can do even with third party replacements these days. We recommend sticking with the stock lock screen if you can because third party options are quickly dropping out of fashion. In addition, with biometric..."

Bluetooth BLE scan stops when advertising stops

I have an Android 6 - level 23 application running on mobile devices that both concurrently advertises and scans BLE connectionless packets.

ISSUE:

I find that when I call stopAdvertising(), the continuous running BLE scan operation is halted or stops working for 1-4 seconds, before resuming again. I know this because I can readily see the continually received ad packets every 0.10 second are not received for 1-4 seconds. This implies the scan operation is halted or stopped when the advertise operation is programmatically stopped.

How can I periodically start and stop BLE advertising without adversely messing up the BLE scanning operation?

I tried developing my application using different Android version APIs with the same annoying scan halt problem:
Android 6 - level 23
Android 8 level 26


Just for reference, here's some snippets of Android 6 code:

// create advertiser and save in list, so advertising instance can be stopped in future.
mBluetoothAdvertiser = mBluetoothAdapter.getBluetoothLeAdvertiser();

// start advertising!
mBluetoothAdvertiser.startAdvertising( settings, data, mBluetoothAdvertiseCallback );

// do some work...

// TESTED BAD - the call below causes the BLE scan operation to halt for 1-4 seconds.
mBluetoothAdvertiser.stopAdvertising(mBluetoothAdvertiseCallback);

AR Emoji

Well the S10 does not have notification LEDs so I find it easy to miss messages or calls. Now the S10 does have notification LEDs that activate around the camera cutouts, thou this feature is disabled at present. You can use a number of apps to activate the feature, but by nature these apps require a HUGE ammount permissions that I personally am not comfortable agreeing too.

Oh ok I didn't see that in update coming for the phone

LGV20 Not Booting, Internal Memory Recovery

Wish I could provide you with assistance but Im mot familiar with LG20's but it sounds like a hardware issue. Your Pc/Mac dose not recognized the device make it all the worse. I can speak from personal experience with a Note 4 softbrick that I spent hours and hourse and hours..... trying to fix. I spent more time that the phone was worth, not to mention all the frustration. A few years later in trying to assist a fellIw Note 4 memer on XDA, I came across a .no-verity-opt-encrypt.zip 6.1 and provided ithe link in the post. Afterwards, I decided to flash it to my old Note via TWRP. I now have 3 working Note 4's lol.
