Over saturated screen colors screen mode not working

Hello, I recently received a used J730f as a gift that it just got it's screen replaced.
It's been updated up to the latest pie update by previous owner.
Here is the problem:
The colours on screen appear too saturated and vibrant. Especially reds. Reds look more like bright orange.
I tried adjusting colours from screen mode but even it I change modes and adjust the colour balance it seems to have no effect whatsoever on the screen.
Same problem with the colour correction on accessibility. Not change for any option. Not even on negative colours.
The only thing working is blue light filter and brightness adjustment.
I downloaded applications and they let me change the color balance but not the saturation.
Any ideas?
Could this be the screen replacement? Seems more of a software problem to me.
Thank you in advance for your time

Google Play Store not working

On my wife's Samsung Galaxy J7 Sky Pro, running Android 6.0.1, Google Play Store has stopped working. When we try to start it, we get a mostly blank white screen for a few seconds, then after a few seconds it starts doing a weird thing where it sort of very briefly shrinks then expands back to full screen size. Then it does that repeatedly, and nothing else, until we shut it down.

The only display is the small row at the very top with things like battery charge, time of day, wifi indication, etc.

I've tried:

-- Restarting.
-- Clearing cache and data for Google Play Store.
-- Clearing cache and data for Google Play Services.
-- Reinstalling Google Play Store.

Any suggestions on what else I can do?

Root Apps that can be safely removed?

Bloatware and such? I'm compiling a list but have bricked my device twice thus far. :-)

com.google.android.apps.plus - Google +
com.microsoft.office.excel - MS Excel
com.microsoft.office.onenote - MS OneNote
com.microsoft.office.powerpoint - MS PowerPoint
com.microsoft.office.word - MS Word
com.microsoft.skydrive - MS OneDrive
com.skype.raider - Skype

So far, I have bricked it when removing certain samsung apps (calendar) and possibly some google apps. but it could be because they had dependencies.

I'm also not sure how much this tablet has in common with other samsung devices as I don't have a samsung phone.

Anyone else have a list that we can append?

Is there a way to rearrange notifications at the top of your phone?

I have a sound profile app. It seems to work well, but for whatever reason, its listed at the bottom of the notifications. When I first drag down on the screen to see notifications, the sound profile app to change the profiles isnt visible unless I drag the list up so I can see the bottom notification. The last sound profile app I used, it was always the first one listed. That one I used to use for some reason doesn't work right on my new phone. This new sound profile app works perfect except it's always at the bottom of the list.

Request a new smartwatch forum

Looking through the forums for the various smartwatches, I noticed watches like Michael Kors and Fossil have dedicated forums... but nothing for my watch: the Montblanc Summit 2. Yes, it's probably one of the most expensive smartwatches on the market - it's also the best smartwatch I've ever had on my wrist! Please consider a "Montblanc Summit" forum: that would cover the Summit 2 as well as the rumored Summit 3, which is expected to run on the upcoming Snapdragon Wear 3300 SoC.

Thank you!

Spyware? Over 20 system apps same storage size

Is it normal for over 20 system apps to have the same size? Also an app called Mysprint downloads several times a day sometimes. After a factory reset it is fine but when I login to my google account it starts acting up and downloads files I didn't request.

Its just fustrating

Losing 4% battery life in 15 minutes.

I would play a little game called Pokemon Rumble Rush to kill free time for hours on my iPhone 8 and my two year old battery was fine. I played it on this brand new Galaxy s10 with the graphics set to the lowest, grainiest settings, on a tiny portion of my screen in pop up view and I lost 4% in 15 minutes after unplugging the phone at 100%. And it's not even this little game, I quit playing the game and just used Feedly, an rss feed viewer and I'm still losing power. Screen is on lowest brightness...I just can't stand how many issues I'm having with this 3 month old phone. Started days out of the box and just keeps getting progressively worse. Samsung Facebook chat had me wipe the partition cache, that didn't help. I have a huge blog post on all the bugs and glitches, this is a nightmare. https://therealredrosealways.blogspot.com/2020/01/my-regrettable-decision-to-buy-1000.html?m=1 The chat person said to take it to a store but when I fly back to the States next month, the nearest of the handful of "experience" stores is in New York City and I can't do that. I don't know what to do with this thing to try to get it to work.

Playing different sounds on different buttons click

Hi guys,

I am new to android and I want to make a simple app for learning purposes.
So the app should be like this: if I press Button1, it will sing the sound1. If I press Button 2 the sound1 stops and plays sound2.
Here is what I made so far, but it doesn't work. I tried to search on different websites, but I didn't find anything that could help me so I thought it would be helpful a forum.
Any help please? :D

Thank you!

Java:
package com.example.moan;

import androidx.appcompat.app.AppCompatActivity;

import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    MediaPlayer cricket;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        Button btnCricket = (Button) this.findViewById(R.id.button);
        btnCricket.setOnClickListener(this);

        Button btnCricket2 = (Button) this.findViewById(R.id.button2);
        btnCricket2.setOnClickListener(this);




    }

    @Override
    public void onClick(View v) {
        switch(v.getId())  {
            case R.id.button:
                closeCricket();
                cricket = MediaPlayer.create(this, R.raw.manea1);
                break;
            case R.id.button2:
                closeCricket();
                cricket = MediaPlayer.create(this, R.raw.manea2);
                break;
            default:
                return;
        }


        cricket.start();


    }

    public void closeCricket() {
        if (cricket.isPlaying()) {
            cricket.pause();
            cricket.reset();
            cricket.release();
        } else {
            cricket.reset();
            cricket.release();
        }

    }
}
