Well, maybe one of you has experienced or maybe just experiencing this problem, “App not installed” when you try to install an application.
Therefore, I will explain several ways to solve this problem easily and you can try it when you want to install any application or game.

Table of Content:

  1. Fix using LDStore
  2. Fix using APKPure
  3. Fix using APK Installer by Uptodown

But before that, make sure you have checked the following:

  1. There is no the same application on your Android;
  2. Check if your memory still has enough space to install;
  3. Check if there are others or comments that the application cannot be installed.

If you have checked these methods, and there are no problems but still can’t install, then you can try the following 3 methods.

How to Fix App Not Installed on all android App

Fix using LDStore

Well, actually this first method is a method that you can only use if you experience this problem when you are playing on a PC and using an emulator, especially LDPlayer. Because I don’t know where you can get the LDStore application apart from the default application from the LDStore emulator.
If you don’t have the LDPlayer application, you can download it here: https://ldplayer.net
Okay, back to the method you can use, please follow the following methods:

  1. First, let’s say you already have the application, so you can immediately open your LD Store application. Then click the 3 lines in the top right corner.fix app not installed using ld store
  2. After that you will find several options. Just select APK / XAPK Management. fix using ld store
  3. Then you will find a list of APKs and XAPKs that you have downloaded and stored in the emulator folder. fix using ld store
  4. Just click install which app you want to install and it will parse automatically. fix using ld store
  5. After the parsing process is complete it will automatically install it. You only need to wait after you click install.fix using ld store
  6. And finally after you finish installing it, you can try to play the game that was just installed.fix using ld store
  7. And if there are no problems in the game, then congratulations that you can start playing. Play Arknights
