Help Android auto annoyances

it could be that you are dealing with old software in your 2018 stock radio and your much newer s21. you can only troubleshoot on your phone side by clearing cache for any apps that the radio uses when they are connected. if clearing cache does not work, you can try rebooting the phone. if that does not work then you might want to consider doing a factory reset. if all that fails to fix the issue, then you might want to start looking into getting a new radio.....or learn to deal with the issues.

Are these apps normal!?

Those apps shown in your screen captures don't appear to be anything out-of-sorts. There's typically a lot of apps and services that run in the background of our phones that pertain to basic functionality, not just apps we might be actively using at the time. For the most part there's no need to bother with micromanaging your phone, the Android memory management is typically more advanced than we humans think we are.

As for that battery drain issue, as others have stated it could simply be a matter where you're just within the effective range of the cellular service from your chosen carrier. In the first screen cap you posted, the cellular service icon in the upper right does indicate a low number of bars. Is that typical for where you're located or were you previously seeing more bars in that icon? You might want to try installing something like this Opensignal app:
https://play.google.com/store/apps/details?id=com.staircase3.opensignal&hl=en_US&gl=US
You can use it to do a speed/connectivity test on your cellular service, and it includes a map (you need to enable Location too) of the signal strength coverage and location of your carrier's cellular towers/access points.
Have you just recently changed your location (moved to a different home or into a different room in your house)? Or any new construction nearby? (i.e. a building or structure between you and the closest cellular tower).

Help WhatsApp restore chat history

So really you setup WhatsApp on the S21 with a different WhatsApp account to your backup from the S9+? I'm not sure if you can import data from another WhatsApp account. You could try WhatsApp on the S21 using your original account email from the S9+?

FWIW recently I also used Smart Switch to transfer data(including WhatsApp) from a Huawei Mate10 to a Galaxy Note20 Ultra. But my WhatsApp account is linked to my phone number, not Gmail, and that transferred my WhatsApp chats etc. no problem.

I believe my WhatsApp is linked to my phone number - when I say Gmail I mean the Google drive account it backs up to. I've changed all the settings on my new phone back to the right Google drive but still nothing. I've unistalled it too many times now and have to wait 9 hours for a new verification code.

Help Newbie question, dont flame

What year and car do you have? Where do you live?
This app is an alternative to just guestimating how often you need to fill up gas based on mileage:
https://play.google.com/store/apps/details?id=com.ovz.carscanner&hl=en_US&gl=US
If relies upon a car's OBD (On Board Diagnostics) so it's reading the actual hard data created by your car's integral electronics system. You'll need to purchase an adapter to plug into OBD port itself though:
https://www.amazon.com/Foseal-Impro...e+adapter&qid=1625799247&s=automotive&sr=1-18
The adapter is the physical interface to your car (the ODB port is typically on the driver's side under the dashboard), the app then uses Bluetooth to link up with the adapter.

Smart Things App (Samsung)

Try perusing through your A5's Settings menu. There's a Notifications listing to tweak options for the notifications in general, and probably more specifically if you open up the 'SmartThings' app menu in the Apps menu, that's where there are options that pertain just to that app. You can alter how you want things like notifications and app permissions accordingly.
You might find it useful to just sit down and go through all the options in your phone's Settings menu. It's a good way to get familiar with your phone's particular feature set. Note that there are often a lot of contextual options and sub-menus, and some of them need to be accessed in different ways (... some use a gear icon, some a three dot icon, some a hamburger menu, some Google apps/services now just use your account icon. Android user interface rules are pretty chaotic.) Just be careful not to alter too many things at the same time, or at least document what you change. Sometimes you disable an important or necessary service so you want to be able to just enable it again.
You might also want to look through the User Manual for your model:

Help how to find out how much space each app is taking in internal memory

You really should not put apps onto an SD card.

They take a performance hit, whether you notice it or not.

Also, as you have seen for yourself, the space you can save is minimal at best.

Pretty much, you are trying to put 10lbs of potatoes into a 5lbs bag.

The best thing,for any device is to keep the user memory at around 70%.

That is because apps grow as they are used, and when theyare updated.
Some space must be left available for this, and remember that the system apps are always running too, so they will also need some more space sometimes.

This fact became extremely clear to me when I got a new device and had not filled it with myfavorite apps yet.
The apps that I had put on it, that were the same apps as my other devices, would get much bigger on the new device, and faster.

Why?
Well, because there is more space for them to use- and so they do.
An app on a device that is already overfull will be compromised and not able to grow as is intended.

Yes, this situation sucks.
Memory is a premium.
Yes, I have been in your position, what with the low cost devices that I use, that have limited resources.

The simple solutions?
A device with the memory required to handle all the apps that I want, ie. $$$- or multiple devices.

For $40-$50 I can get another device, and have great performance for my apps.

A bit of a pain?
Sure.
But nothing compared to trying to move apps around with poor results and then constantly monitiring (or trying to) how much memory each app is using.

I have resisted the urge to get a tablet, as they cost much more than a phone that has better specs.

Use your SD card for personal media- pics, videos, documennts, etc.

Use the internal memory for apps.
If there is not enough room, then you need less apps or more memory.

Video and Image Apps Able to Open One File Only

Still, your best option is to stop trying to use any file manager as a way to access media.

File managers are designed to do just that- manage files- moving them, renaming them, etc.- not to view file after file.

Open your media in a media player to do that.

Simple File Manager Pro and Simple Gallery Pro are both excellent choices that work well together.

https://specs-tech.com/en/Comparison/zte-blade-a5-2020-vs-zte-avid-579/

I hope others here will verify better, but I suspect the 579 does not support USB OTG connections (On the Go), either because of the hardware or that it runs Android 10 Go Edition (a slimmed back Android OS similar to Nokia 2 series and others).

That link is the closest I can find to verifying that.

ZTE removed most of the specifications on their site.

This also means, as I can recall, the device won't support usb flash drives or MHL TV connections.

Definitely check for OTG capable devices if you want to replace.
GSMArena is usually the best source of detailed device info, but I couldn't find your device listed there.

Best app to play audiobooks?

On which platform do you listen to and download audiobooks? If you are an Audible user, you can only play them on limited devices because Audible files have DRM protection. If you want to play your audiobooks on many players without limitation, you should use some tools to remove DRM protection first.
Speaking of the useful tool, you can use DumpMedia Audible Converter to remove DRM protection and convert your files to some common formats. It has a fast conversion speed and won't cause quality loss.
After converting, you can play your Audible books on many players. And you have many choices to select.

App Inventor Luminance Detected : High Ambient Light is Detected Bug

I'm not a dev of course, so my advice maybe limited. is your app is trying to override automatic display brightness setting, to dim the display down? Is it happening on certain Android versions, like the more recent ones, e.g. 9, 10, and 11?

One point "block blue light from your screen". Android has that built in, called "Eye Comfort" or similar, in the device's Settings. With various options for it.
That was one idea in my mind too, but before trying it out I thought let's try doing it manually and I reduced my brightness to the lowest but the popup still came, and it makes sense. The ambient light sensor detects the surrounding light and if it's too bright, it is going to show that popup. Most of the devices are Android 10 and 11 as I can see from stats. And, I know there is a built-in eye care feature in most devices. But they are targeted toward reducing eye strain and protecting eyes. The motive of my app was to help people suffering from migraines. I did good amount of research and there is a specific color of green that helps people with migraines a lot. So hence this app.

Not allowed to change Do Not Disturb state, using AudioManager setRingerMode(int i) in Worker

Hi!
I am making an app that needs to set the ringer mode to silent, when i run the AudioComponent.Ringer Mode Silent block an error occurs:
“Not allowed to change Do Not Disturb State”, both in companion and in apk.

I granted all the required permissions but still doesn’t work.
I’ve also tried to grant Access to Do not disturb state from the phone’s settings but i haven’t found my app in the list.

Tested with two phones: Samsung J7 pro and Samsung S8+, both with android 9
Thanks

Heart on top notification bar

What is that pink heart notification for? It is on my boyfriend’s phone
Thanks
we get this question everyday. the problem is that there are millions upon millions of apps out there....especially ones with a heart icon. so unless it is something like facebook or youtube, most of these threads go unanswered.

a heart icon could be anything from a fitness app to a dating app. its a pretty generic icon.. the only true way to know for sure is to either trust him or just ask him.
