Failed to root SM-N9200, need help.

ocnbrze
you should have made a nandroid backup before flashing the kernel. a nandroid backup is a complete backup of your phone, incase something like this happens. as long as you can get into recovery you can always restore a nandroid backup. well, let's make this a teaching lesson.

so looks like not many roms or kernels supports n9200 variant of the note 5. you have to be very careful on what you flash. kernels and custom roms are very device specific. you need to read the op and the entire thread for each custom rom or kernel, before flashing.

the only thing i can think of is to flash a firmware for your device. go to sammobile. it might unroot you however, but i'm not 100% positive.

Help Water stains on Samsung Galaxy Tab A

Well, if its water and it is still wet, then if you apply pressure with a finger you will see it move around.

If it doesn't move, then it is probably dry and unless you can disassemble the screen components to clean it then it is probably going to be there for a while.

Did you drop it into the tub, or just touch it with wet hands?

Hey, thanks for your answer. I'll do that.

Battery wont hold charge

puppykickr
Try this:

Plug your phone into the charger and then plug the charger in.

Goto:

Settings
Battery

Look to see if it says Charging on USB or Charging on AC.

If you are plugged into a charger (not a USB port) and it says Charging on USB then try a different USB cord, until it says Charging on AC.

If nothing helps, then change the charger and try it again.

Cords wear out over time, and so do chargers

Why can I not download apps from Google play?

Hamster Wheel Problems.
I like that description.
Sounds like an app on the Play Store.

Get this.
I have one app, Demolition Derby 3, that I cannot get to update unless I have the recent Play Store and Services updates.
They both nust be current even to update it from a different app store.

So as soon as I do that, I have to disable the Play Store app, so that Google won't mess with my device again.

Chrome does not synchronize

MoodyBlues
Welcome to Android Forums, newnexo!
Chrome does not import my bookmarks (and everything else) from my Google account.

If all else fails, you can create backups of everything you need and then import them on the S10.

Start by going to Google's 'Download your data' page, and scroll down to Products. Select whichever item(s) you want, then just step through creating their backups. I think I'd do one at a time, i.e., bookmarks, then contacts, etc., simply because it's more straightforward with less room for confusion.

Once a backup has been created [and unzipped], you'll be able to import its data into the appropriate apps on the S10.

If you need help with any of this, just ask! :)

Help Powerbank voltage and amperage help

Something to keep in mind is USB charging standards continue to evolve so 5 volts applied to USB 1.x and 2.x but now with USB ver. 3, USB power is up to 20 volts.
https://en.wikipedia.org/wiki/USB#Power
Also, USB v3/USB Type-C have become more and more fractured as they've become victims to corporate oversight and proprietary lock-in, so the 'universal' in USB is becoming less and less valid:
https://lifehacker.com/why-your-usb-cable-might-not-charge-your-android-smartp-1840462438
https://people.kernel.org/bleung/how-many-kinds-of-usb-c-to-usb-c-cables-are-there
Your cabling is more likely something to be focused on so it's compatible with your phone, your charger less so. Just be sure to use a charger with adequate wattage, plus something that is a fixed matter -- amp x volt = wattage. So with that powerbank rated at 2a x 5v = 10 w; and that 4500mAh battery can theoretically take in 4.5 amps (1 amp = 1000 milliamps) it's going to work out OK but not optimal. But most consumer charging devices aren't rated to supply that much amperage anyway so it's not that much off the mark.

Thanks for the info, I will take a look at the given links and consider everything when buying a cable. Cheers!

Hello fellow users and citizens of the internet,

I intend to keep the health of my Galaxy A70 battery (4500mA) optimal for as long as possible, I try to keep my charge between 30-80% when possible, avoid fast charging when I don't need it (supports 25W charging), avoid high temperatures, rarely completely discharge or recharge it.

All of this and I still don't understand how voltage and amperage work in terms of battery health and safety.

Because I need to keep the charge between the mentioned interval I need to carry a powerbank, however, as far as I understand the voltage/amperage supported (5V;2A) isn't the same of the charger. I haven't used the powerbank yet because I need to buy a USB-to-USB Type-C cable, before I make the purchase I wanted to know if I should even use that powerbank so If anyone can share some knowledge, I'd appreciate it!

I've uploaded a photo of the device's charger and what it says.

Thank you and cheers!

Help Trouble with Facebook on my Samsung Galaxy Tab E 9.6 Tablet

svim
Are there any options in the Facebook app on your phone that might look like they might be in some way tied to what you're seeing through the app's user interface? If you use a browser app to access your Facebook account does that work out any better?
Keep in mind that your actual Facebook account data is all managed and sourced within Facebook's online servers. It's always a server <<<>>> client matter where your Facebook account 'exists' within Facebook's servers; and what you see in your desktop browser, or your mobile device, or wherever is simply the on the receiving end, the client.

AR emoji

Late to reply to this one.

Startup your camera app, go into the More area and then select AR Emoji. Here you can create and edit them, however if you go into the settings here you can request a app shortcut be created to make it easier to use.

How to add SQLite rows to an ArrayList<>

Assuming you want to create an Array of Strings, as you've declared

Code: 
ArrayList<String> info

then just write

Code: 
info.add(check.getString(check.getColumnIndex(TableClass.Name_Column))

Assuming TableClass.Name_Column is a string value.

If you want to create an ArrayList containing objects corresponding to the rows in your database table, then you'll have to create a class that represents all the data fields in that table. E.g.

Code: 
class Person {
  private String firstName;
  private String surName;
  private Integer age;
}

then create Person objects using rows retrieved from the database, and declare an ArrayList like this

Code: 
ArrayList<Person> people = new ArrayList<>;

android 10 : android.process.media keeps stopping when invoke downloadmanager

huynq0911
Recently I start testing my app in Android 10 (it works fine on the previous version). When I invoke download manager for a file, I got a crash with a message:

android.process.media keeps stopping

This is my snippet code:

String mFilePath = "file://"
+ FileManager.getInstance(getApplicationContext()).getDir()
+ "/"
+ fileName
+ extension;
Uri downloadUri = Uri.parse(fileUrl);
DownloadManager.Request req = new DownloadManager.Request(downloadUri);
DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
dm.enqueue(req);


What's the exact problem?
