Why do programs freeze and crash? What causes the operating system to freeze and crash? How to fix them?
The operating system and programs are far more than they appear. When you click on a button, there are many tasks and processes working together, for the desired effect to be achieved. Unfortunately, if one of those tasks and processes won't serve its purpose, or there is a compatibility issue with the operating system, or other programs, errors occur.
The most common reasons for programs and apps to freeze or crash are:
The solutions listed below will show you how to stop programs from freezing and crashing. They work on computers running on Windows (Dell, Lenovo, HP, Acer, Asus, and more), as well as smartphones, and tablets running on Android (Samsung, Huawei, Xiaomi, Sony, and more), and iOS (iPhone, iPad, iPod touch). Check them out, and follow the instructions.
As programs are more than they appear, i.e. they are actually a set of tasks and processes working together, errors are bound to happen, especially if one of the components becomes unresponsive. By restarting your device, you will reinitialize all the stuck components of the program (unfreeze it), as well as the operating system.
Turn off your device, and turn it back on after 2 minutes.
Just like we need air to breathe, programs need space to work. When a program runs, it requires memory which can be used associated to it. Another reason for a program or an app to freeze is due to lack of disk space or memory. Remove files you don't need, especially from the internal memory of the device, and run the program again.
Check out the running out of disk space / no space left guide to learn how to free up disk space (or memory).
Updating the operating system to the latest version is more than patching bugs. It brings speed improvements, as well as the latest system tools and trends the apps need to be aware of. One of the reasons why app(s) might be freezing is because of incompatibility of the app with the system. In this case, updating your operating system via Settings might fix the problem.
If you are not sure how to update your operating system, check out the how to update my device's operating system guide.
Apps might freeze because the phone doesn't have enough memory available to allow them to function properly, which is probably loaded with other open apps. To free up memory and unfreeze your device, you need to close apps.
To close all open apps, long press Back button and pull down (close) all of them. After that, launch the app you need, again.
As pieces of software, extensions, and websites rely on your RAM to be able to stay as they were, the browser can crash if the RAM is overloaded by too many requests (e.g. too many tabs are open).
In this case, to resolve the issue, you need to close the tabs you don't need, and then reload the ones you need. You can also close the web browser, and reopen it.
