The situation when clicking on the icon of your favorite instant messenger or banking client does not lead to any result is familiar to many users. The screen may simply blink, or you may see a message saying that application has stopped. This does not always mean a fatal failure of the device. Most often, the problem lies in a software conflict, full memory, or outdated system components.
Analysis of the causes of the failure requires a consistent approach. Sometimes the culprit is a recent operating system update Androidthat was not installed correctly on a specific smartphone model. In other cases, a conflict occurs between two installed apps sharing the same resources. Understanding the nature of the error is the first step to eliminating it without losing personal data.
Primary diagnosis and system reboot
The simplest solution is often ignored by panicked users. Rebooting the device resets temporary processes that might be stuck in RAM. If the application does not open after turning on, try not a normal reboot, but a full pause of 10-15 seconds before turning on again.
In some cases, a standard reboot does not help clear the system services cache. Then you should use the function forced reboot. For most models Samsung, Xiaomi i Pixel this is done by long-holding the power button and the volume down button simultaneously for 10 seconds.
⚠️ Attention: If after a reboot the problem persists with only one specific application, and the rest are stable, the problem is not in the system, but in the software itself software.
Before performing complex actions, make sure that the battery charge is at least 30% so that the phone does not turn off during the diagnostic process.
It is also worth checking for system updates. Go to Settings → System → System update. Sometimes Google releases security patches that fix critical compatibility errors that arose after previous updates.
Clearing the cache and data of a problematic application
Accumulation of temporary files is one of the most common reasons why software stops working respond to commands. The cache speeds up work, but if it is damaged, the app cannot be initialized correctly. Clearing this data is safe and does not delete your logins or passwords, although it may reset some settings within the application.
To perform the clearing, you must go to the application management menu. The path may vary depending on the shell, but usually it looks like this: Settings → Applications → [Select problematic application] → Storage. Here you will see two buttons: “Clear cache” and “Clear data.”
- 🗑️ Clearing the cache deletes temporary files that speed up the loading of pictures and scripts.
- 💾 Clearing data resets the application to the “as after installation” state, deleting accounts and settings.
- ⚙️ Forced stop before clearing ensures that the process is not running in the background.
If clearing the cache did not help, try the option of completely clearing data. Attention: This action will require you to log into your account again. After completing the procedure, try running the app again. In 80% of cases, this solves the problem of freezing on the splash screen.

Version conflicts and component updates
The Android digital ecosystem is complex and depends on many components. Often the application does not work not because of itself, but because of outdated Android System WebView or Google Play services. These system add-ons are responsible for displaying web content inside applications and authorization.
You can check the relevance of components through the store Google Play Market. Search for "Android System WebView" and "Google Play Services". If there is an "Update" button, be sure to follow this action. After the update, a mandatory restart of the smartphone is required to apply the changes.
| Component | Function | Risk of obsolescence |
|---|---|---|
| Android System WebView | Opening links within applications | High (application crash) |
| Google Play Services | Synchronization and Push notifications | Critical (working of all software) |
| Google Play Store | Installing and updating apps | Medium (loading errors) |
| Android System | Base operating system | High (instability) |
Sometimes the problem occurs after updating the application itself to a new version that contains bugs. In this case, the logical step would be to roll back to the previous version. This is possible if you download the installation file .apk from third-party trusted resources, but requires caution.
How to roll back the application version?
Go to the application settings, click on the three dots in the corner of the screen and select "Uninstall updates". This will return the factory version of the app built into the firmware.
Lack of RAM and permanent memory
Modern applications require significant resources. If your device's internal memory is more than 90% full, the system may be blocking new processes from starting. Android allocates space for swap files and cache, and if they are absent, the application simply cannot deploy in memory.
You can check the fullness of the storage in the section Settings → Storage. If space is critically low, delete unnecessary videos, photos or transfer them to cloud storage. It is also worth emptying the trash in the gallery, since files there continue to take up space.
⚠️ Attention: Do not delete system files or folders with names whose meaning you do not know. This can lead to complete inoperability of the smartphone.
RAM (RAM) also plays a role. If you have two dozen applications open in the background, there simply won’t be enough space for a new one. Use the Clear All feature in the multitasking menu before launching a heavy app. On some models Honor or Oppo there is a function for expanding virtual memory, which should be activated in the settings.
Free 10-15% of internal memory is a prerequisite for stable operation of heavy applications and social networks.
Access rights errors and energy saving restrictions
Aggressive power saving settings can kill application processes immediately after they are launched. The system considers the app a “parasite” that consumes resources and blocks its activity. This often happens with instant messengers that stop loading messages or opening.
You need to check the battery settings for a specific application. Go to Settings → Applications → [Application name] → Battery. Make sure the mode is set to No Restrictions or Unlimited. Standard mode may be too restrictive for background work.
Also check your permissions. If an application is denied access to storage or network, it may crash on startup. Go to section Permissions and grant all the necessary rights, especially access to memory and phone. Without this, modern software often cannot undergo initial initialization.
Reset settings and radical measures
If none of the above methods helped, it is possible that deep software errors have accumulated in the system. In this case, resetting the settings to factory settings helps. This is an extreme measure that will delete all data from the phone, so make a backup copy of your contacts and photos first.
You can perform a reset through the recovery menu (Recovery Mode). Turn off the phone, then hold down the combination of buttons (usually Power + Volume Up). In the menu that appears, select Wipe data/factory reset. Confirm the action and wait for the reboot.
⚠️ Attention: Recovery menu interfaces may differ on different devices. Before entering, check the instructions for your specific smartphone model so as not to erase unnecessary items.
After resetting, the phone will be like new. Do not restore all applications from a backup in batches at once. Install them one at a time and check their functionality. This will help identify which application caused the conflict in the system earlier.
Alternative to a full reset
Try creating a new user in the system settings. If applications work on the new profile, then the problem is that the main user's profile is damaged.
Frequently asked questions (FAQ)
Why do applications crash immediately after updating Android?
The new version of the system may have modified libraries with which older versions of applications are incompatible. Solution: update all applications on Google Play to the latest versions that support the new OS.
Can a virus block apps from launching?
Yes, malware can intercept control or block the operation of legitimate software. Scan your device with a built-in antivirus or a utility like Dr.Web Light.
What to do if even the application store does not open?
Try to clear the data of the application itself Google Play Market and the service Google Play Services. If it doesn't help, check the date and time on your phone - incorrect settings will disrupt security certificates.
Does a full DNS cache affect the opening of applications?
Yes, if the application requires a network and the DNS cache is damaged, the connection will not be established. Try turning Airplane Mode on and off or rebooting the router.
