[Q] Trouble with applications

After using the S7 in the A1 version for a while, there is a couple of questions arising to me:
I did the mistake of installing Twidroid PRO which now withstands all attempts to get removed. Even worse, it will start in the background every time I restart the device. I really want to get rid of Twidroid.
Whatever I do, I cant get any QR reader to work. After googling for the problem it seems, that some other S7 users experience the same trouble, while others dont. Maybe depending on the type of camera installed. Any ideas?
Some very basic applications, like Google Goggles, are not visible for S7 users in the Android Market. A few can be found on alternative sites and do work fine, but most apps stay unreachable. Is there a way to get those apps ?
Thanks for any hints to get more happy with my S7.

as for twidroid, root your device and uninstall it once its rooted, I will take a look at getting google goggles tonight and let you know

Thanks for your help. I did root the S7 and after some more fruitless attempts to delete Twidroid, I found the reason - but not the solution:
Twidroid disguises as a system file that resists any attempts to delete or to uninstall. Basically, the typical behaviour of malware.
This makes me even more worried about Twidroid and its "mission".

Removing system apps
Hey Ossyris,
Did you check out:
forum.xda-developers.com/showthread.php?t=942166
He seems to be removing twidroid "rm Twidroid.*".
Personally have not done this yet... but I will soon.

Essential apps/services closing when close button is used

I'm running on Resurrection Remix based on CM13 where you can configure the Navbar with extra buttons including a close (x) button that very much closes the app on the foreground. However, i found that with this single action, a multiple of other apps running in the background with essential services are also being force-closed. And that includes Kaspersky Internet Security and a firewall (NoRoot or WebGuard, both exit). The icons representing the apps disappear the very next moment from the status bar after tapping the close button. To confirm, I cross checked the running services. However, a couple of other apps run regardless, like the Internet Speed Meter, BBC News, Google Now etc.
Now, i know that a simple solution to this problem is to operate and use sans the close button, but I'm really hoping that there's a workaround on it, counting on the fact that some apps persist and some don't.
Can someone please suggest a solution. Any help is appreciated. Thanks.
Additional info:
I tried prioritising the apps using Memory Locker. Even converting KIS to be a system app. None of the methods worked. I can provide more information if i missed any. Googled for all possible solutions I could find, in vain.
PS: I'm unable to attach the screenshot; says network failure on both data and wifi :

S Planner notifications came back from the dead

Hello all. I was disabling a few apps on my SM-T280 (no root). A little while ago I purchased a font via Samsung and was introduced to "Samsung Billing" app. After that I noticed "Samsung Music" received an update. I don't want to use it, so I uninstalled updates and cleared its data. It kept coming back, so I found out I could disable "Galaxy Apps" to fix that. So far, so good.
Storage space is at a premium on this 8GB device, so I went looking for ways to cut corners. I disabled:
Galaxy Essentials Widget
Samsung Billing
Samsung Galaxy
Samsung Push Service
S Planner
according to a detailed forum post (not for this device) on which apps can be safely disabled.
Now all my Google Calendar items are being called out by S Planner, and I can't make them stop. I've tried re-enabling the original S Planner app and clearing its data then rebooting.
A few questions:
Are there supposed to be two S Planner apps listed? One can be disabled and uncheck notifications. The other cannot.
or did Android somehow reinstall it to a new instance?
If there is a solution, do I need root? I'm willing to try again, after failing last time. I think I need to decrypt the device first.
will rooting cause me to be forever unable to get official Samsung updates? (such as a patch [hopes] for the WPA2 KRACK exploit) I did have trouble checking for updates, as "the device has been modified" or something, but all I had to do was get rid of TWRP.
This app actually woke me up in bed, so I need to kill it. Hopefully without losing all my apps & data...

I do realize that disabling those apps doesn't save any space, but keeping "Samsung Music" from updating saved quite a bit, so I went down the list, just to be thorough, potentially free up resources.

well that was quick. I figured it out... for *some* reason, I had to go into S Planner and disable notifications. yeah obvious... but I don't think I ever had to do that before... so for some reason, disabling the app caused this problem to start, so I'll leave it disabled now.

feel free to delete this thread, if it's not useful to anyone else.

prevent block remove Google Playservices for INSTANT Apps

HOW I DISABLED Google Playservices for INSTANT Apps
DISCLAIMER: Tweaking these apps and services can leave you with a broken, non-functional, steaming, smoking, screaming device; proceed at your own 
risk. Just because I got it to work, doesn't mean it will work for you. I am not responsible for your PEBKAC errors. All Google stuff on my devices is extensively neutered, if it's not on your this may not work. I prevent updates to Play Store and Play services and the brunt of services run by those apps are disabled there's too much there to be covered in a simple guide but this instruction is what FINALLY clipped INSTANT APP'S wings.
 I thought I'd found a way to prevent it from re-installing itself, but after two days it did, but at least this turns it off and keeps it from hogging battery and as much memory. As many have pointed out, freezing doesn't, but but turning off the SERVICES as outlined here, it slows it down a lot.
ROOT IS REQUIRED, the only way to block it without root I know of is disable the Play Store, go someplace else for that and don't hijack this information, it's not about using 3C, facebook, Play store, relationship problems or political unrest, it's about STOPPING Google's Apps: Play Store & Play Services from installing "Playservices for INSTANT Apps"
I think the PLAY STORE downloads and installs “Playservices for INSTANT Apps” under control of services run by PLAY Services
RECOMMENDATION: Every release of Play Store and Play services potentinally includes NEW services that might affect this solution. I recommend each time they are updated you check for NEW items that might trigger installation of Instant apps.
THE SOLUTION:
=============================================================
Using 3C All-in-One Toolbox" from 3c71 dot com
"Manage">"Application manager">"Apps">"Google Play store">"Manage">"Permissions">"Activities">search (with magnifying glass on toolbar)
input package name "instantapps to filter and uncheck items. Do the same for "Providers", "Receivers" and "Services"

NOW, UNINSTALL/DELETE/REMOVE the app: Google Playservices for INSTANT Apps.

This is working for me on Samsung Galaxy S5 (G900V Lollipop), Core Prime (G360T), Core Prime G360V, J1 (J100M), LG VS810P and MemuPlay Emulator.
Call it what you want, Malware, Spyware, Shovelware, Vaporware, Bloatware to me Google Playservices for INSTANT Apps is all those things. I saw Google Playservices for INSTANT Apps on my phone December 2018 and cringed. It's taken me almost 4 months to come up with this working solution. When I say WORKING, I mean it prevents Google Playservices for INSTANT Apps from reinstalling and still leaves Google Play Store functional.
THANK YOU! to the dev of 3C All-in-One Toolbox for providing their awesome tools.

Amazon Shopping apps instantly crashing with white screen

I have a Fire10 tablet (7th gen) that is systemlessly rooted with magisk.
Everything works fine on it apart from When i try to open the amazon shopping app, it shows a white screen and then closes.
I have tried;
Force stopping the app
Clearing data & cache
Uninstalling and loading from the google play store & side loading the apk
converting the freshly installed apk to system app then Clearing data & cache
none of this has helped.
The time and date is correct, and magisk is set to hide from the app aswell.
Any ideas ?

Did you run FireToolBox, a de-bloating script or do manual de-bloating on this device?
My Fire is completely divorced from Amazon, so I can't check this, but as you run the Amazon shopping app, do you see the Location Services icon (triangular compass pointer to the left of WiFi indicator) light up momentarily before the crash?
If your Location Services are broken, or you have disabled any or all of:
com.amazon.device.messaging
com.amazon.device.messaging.sdk.internal.library
com.amazon.device.messaging.sdk.library
Then some apps that access Location Services will crash (and I bet Amazon shopping wants to know where you are to offer targeted deals). For example, Instagram pings Location Services on startup, if any of these items are disabled, then Instagram crashes before it can fully start.
These 3 items are usually recommended to disable or delete in most of the de-bloating guides I've seen, and they should NOT be.
