Sometimes it happens that system applications on smartphones stop responding and give an error. This happens for various reasons – from lack of memory to uninstalled updates. The problem can be solved in different ways, which we will discuss in this guide.
Rebooting the device
A cheap and cheerful method. The simplest option that helps fix most problems related to system failure. To reboot the device, hold down the power button or press the appropriate command.
Clear cache and delete temporary files
Cache and temporary files can clog up memory, the lack of which not only slows down the gadget, but also leads to errors in the system. Therefore, do not forget to clear the cache and delete unnecessary temporary files from time to time.
To do this, you need to use the built-in “cleaner program”. It is enough to run the scan and at the end clean the found garbage. Special utilities, such as CCleaner or Clean Master, are also suitable for this. With such software, the entire procedure will be not only correct, but also fast.

- In “Settings” open the “Date and Time” section;
- Uncheck or move the slider to the off position opposite the items “Adjust time automatically” and “Adjust time zone automatically”;
