What is Is Samsung input event app a virus? How to fix this app from being stopped or crashing. Know in deep about all. A cell phone is one of the basic requirements nowadays. And the importance of cell phone is growing with every passing day. This is one of the most significant realizations of this generation during this pandemic situation. If we look at the statistics, 80% of cell phone owners are users of android devices.

The main reason for this is that, the android in the android cell phones were freely made available for the users right from its first model, unlike other operating systems like the iPhone. Adding to its benefit, google made almost all the apps freely available for android devices. As we all know that Appstore avails charges for many of its apps compared to the play store. And the main reason for the increase of androids in the market compared to others, is its affordability. Not only the affordability, but also the wide spectrum of functionality.

What is is a package name. On breaking it into parts: “com samsung input event app,” we can understand the basics. In a samsung android device this package get imported to take a input event from the touch screen.

So, for any device, inputs and outputs are the building blocks. The inputs for android cell phones are touch (touch screen cell phones), buttons, camera (for face recognition), various types of sensors (light sensor, motion sensor, fingerprint sensor, etc.), and voice commands. Every input of an android cell phone is associated with some form of the desired output. The cell phone outputs are in the format of display, sound, or motion, i.e., vibration. The way between input and output of the cell phone includes some internal processing. This internal processing is called android input events or event listener or input handling. This is a part of UI (user interface).

Examples of samsung input event app

There are fixed mini-programs to be implemented when any kind of input is given to the android cell phone. The examples are as given below:

  1. Onclick(): This mini program is used for the touch on-screen or enter key.
  2. Onlongclick(): This mini program is implemented when the user long presses on the screen.
  3. onFocuschange(): This mini program is implemented when the user navigated away from the screen.
  4. Onkey(): This mini program is implemented when the user presses the cell phone’s hardware keys.
  5. Ontouch(): This mini program is implemented when any kind of touch is detected by the android screen.

These are just some of the basic examples of input events used in the form of a user interface. There are many types of inputs that an android cell phone can process, and each function has its mini-program or can also be called as a mini code.


           Customization is moulding the functions of a thing according to personal requirements. Hence customization is a luxury option in any case. Customization of cell phones can also be done. Customizing a cell phone consists of changing the cell phone’s operations when a button is pressed on the screen is touched, or it can also be a particular voice command. We can note this thing here, that all these are different types of inputs. Hence, customization of these kinds of input events is also possible. This can be done by creating a new event and programming for it. The programming or coding can be done in different formats like XML format, java format, python-format, or any desired format. The code below shows the programming required for the action of showing text by pressing a button on an android cell phone.

And by implementing the program as mentioned below, the output obtained is as shown as a button. The output screen shows the button on the screen “click input event.” When this button is pressed, the desired action( input taken) can be performed on the cell phone. And the customization of the desired action is done with the customization of the code, i.e. program:[ref]

Button code in XML

android:onClick="Input taken"
android:text="Click Input Event"/>

OnClickListener for Button

Button button = (Button) findViewById(;
button.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        // Take an input when button get clicked

           But for customization of cellphone, the effort to output ratio goes very high: i.e., a lot of effort is required if the conventional method is followed. This is the reason, an app for doing these kinds of changes is available. The app is called The latest version available of this app is 1.0.0, it consists of 63 internal files. The size of this app is 0.33MB. But if we get into details of the app, one will get to know that it has viruses hidden inside. This happens if the source is not an authorized one or even due to malicious viruses through internet attacks, the input event apps quickly.

Is a virus?

This app itself not a virus, but it may contain virus if an malicious code taken as input in the event. How will one understand if the phone is hacked or not? As these viruses are in the phone under the name of system app file names, there are very thin chances to identify the exact virus file. Though, there are some signals available in the phone to understand this. We must be able to decode these signals. Some of the signals that the android cell phone is hacked are the battery of the cell phone discharges very fast, the android cell phone may suddenly get very slow, the cell phone heats more than it normally does, in some cases the cell phone may restart, increase in data usage, undesired operation by the android cell phone on pressing a button and many more.

Solution to fix the virus

           Now the question arises, how to get your android cell phone away from these kinds of malicious viruses caused by the input event app. Here a way to get away from these malicious viruses is given below.

Method1: Ultimate solution

If you search on the net rigorously, you will reach the conclusion that the ultimate solution to this virus is the factory reset. If one wishes to go for this option, you will get your android cell phone cleaned up like a brand new one. But the disadvantage of this option is that you will lose all the saved data in your android cell phone. There must be some other less critical option if searched. See also, how to fix a Hacked android phone.

Method2: Remove some app

The other option if searched further is, remove Bluetooth share, apps store certificate installer, hidden menu, device manager, google partner, setup.mail@metro, MetroPCS easy WiFi. But if one opts for this option, this may make you wish a final good be to your cell phone. Though this is one of the options available on the internet, this may lead to a permanent memory loss of the cell phone. Never in a cell phone removing setup.mail@metro and MetroPCS easy WiFi is a good idea.

How to fix

Method1: Calendar settings

Since our topic is a part of calendar settings. It is always advised to reset the calendar settings. Resetting these calendar setting option not only removes away the malicious virus but also does not do any harm to your android cell phone. But opting for this method may cause the calendar app in your android cell phone to stop. To restart this application, you may do the following small steps. There are two methods to change the setting of the calendar in your android cell phone. Firstly, make sure that you have the updated version of the calendar app in your cell phone. This checking can be done by going on the play store. In playstore, search for the calendar. This is already installed in your cell phone; check if any updates are available. If there are, make sure you download the updated version.

Method2: sync option

If the problem is solved by updating the version of the calendar, then well and good. But if the app still crashes, now you can go for the first option. In the settings of your android cell phone, go to the settings of apps. In there, navigate to calendar settings. Further, check if the sync option is enabled. Sync is the synchronization of saved data into the calendar. You can go one step further and enable the option of auto-sync. Enabling this option will make sure that your calendar s always synchronized.

Method3: Clearing Cache, Data, Uninstall, Force Stop

There is a significant possibility that your calendar may work finely after this, but still, if the problem continues and the app is still crashing. Then you can go for the second method. This method can also be called as clearing the calendar app’s data. For this method, navigate to the settings of your android cell phone. In the settings of apps, Navigate to the calendar settings option.
Clear cache and data of

There you will find two options, ‘Uninstall’ or/and ‘force stop’. Out of the two, navigate to the ‘Force stop’ option and select the option. Then select the option ‘OK’. This is still not enough, go a step forward and go for the option storage. Then navigate to clear data. By following this method, you may lose your data from the calendar. But the app will indeed operate smoothly once the process is completed. In storage, navigate to clear data and select it. By doing so, your data will be erased.

But along with the data, if any malicious files were present. They will also get cleared. Now close all the apps from your cell phone. And now you may relaunch the calendar app. By adding the desired events, you can check if the app runs smoothly. There is a very dense possibility that your issue is solved doing this process.


In conclusion, we can state that there might be a possibility that may have a malicious virus. And the removal of the virus is explained in the article above. If all instructions are followed, by the end, your cell phone will be operating smoothly.
