The storage memory of the mobile phone can be expanded by inserting the memory card separately, and the memory bar of the computer can also be purchased by yourself. So why can't the mobile phone's RAM be expanded? This is really confusing, but you have to consider old phone batteries that you can replace yourself. Mobile phone batteries are not easy to replace nowadays. From this point, you can find some problems. Integrated design is the future trend. In the future, all SIM cards may be virtual!In the future, the built-in memory of the mobile phone will be sufficient, and there may be no need to insert a memory card, because a lighter body is the future direction and no physical SIM card is required, so RAM needs to be upgraded to run the memory. Some people may think that professional maintenance personnel can upgrade, remove the storage on other phones, and install it on their own phones. This idea is more difficult to realize. Motherboard soldering technology cannot be provided by a repair shop. The most important thing is the system compatibility issue. Unlike the Windows system of the computer, the mobile phone is unified. Each manufacturer's system must match the running memory. Generally, outside mobile phone shops do not have this kind of matching technology, so theoretically it is more difficult to expand the RAM running memory. Even the integrated storage memory will have matching problems, not to mention the running memory. After Apple expands, it is always unable to upgrade and refresh, and the system may crash.Google introduced a modular mobile phone with a separate RAM expansion, but in the wrong direction. The development of smartphones is highly integrated. The life and experience of mobile phones are affected by many factors. It is not that you can change to a solid-state drive like a computer. Continue to use for several years. For mobile phones, changing a running memory may not be faster, unless you change the processor, battery, running memory, communication module, and screen, which are all brand new, but this is not the same as buying a new mobile phone.
