The expert named the reasons for the unstable operation of mobile applications

The same mobile application may exhibit different performance depending on the device.: It works quickly and stably on one smartphone, while on the other it freezes, slows down or does not start at all. The reason lies not only in possible development errors, but also in the technical differences of the devices themselves, Anton Bukarev, an expert in the field of mobile development, told Izvestia on May 2.

According to him, although the user installs the same product, the application runs in different technical environments. Smartphones differ in processor performance, RAM size, operating system versions, graphics and screen characteristics, as well as energy-saving features and background processes.

"Such differences are especially noticeable in ecosystems with a large number of device models and a variety of technical configurations. Even in more standardized mobile environments, completely identical operating conditions do not exist, which also affects the stability of the program," the specialist noted.

He explained that for developers, each smartphone represents a unique combination of parameters that must be taken into account when creating and testing a product. At the same time, it is almost impossible to test the application on all existing devices, because it would require significant costs for the purchase and maintenance of a large number of equipment.

For this reason, companies test applications on the most common models specific to their audience. For small teams, the task is especially difficult due to limited resources, so owners of rare devices sometimes encounter errors before other users.

According to the expert, the performance of the processor, the amount of RAM, the features of the graphics subsystem, the limitations of the operating system, the operation of the camera and other hardware components, as well as the behavior of the system in the background, most strongly affect the operation of the application.

A lot depends on the type of application itself. For example, services that actively use the camera are particularly sensitive to the hardware features of the device, while memory and computing power are critical for complex interface solutions.

Most often, problems manifest themselves in the user interface or functions that depend on system components. This may result in incorrect display of elements, failures of individual functions, or unstable operation of the program. After the release of the application, work on it does not end: developers continue to track crash statistics, analyze user scenarios, and promptly release fixes.

Special attention is now being paid to the use of artificial intelligence (AI). According to the expert, such tools already help to analyze logs, identify recurring errors and find non-standard work scenarios.

Alexander Khaminsky, a lawyer and head of the law enforcement center in Moscow and the Moscow Region, reminded on April 1 that Russians will be able to cancel a paid subscription to online services if they unlink their bank card from the service's personal account. He clarified that the relevant law came into force on March 1.
