Each manufacturer of mobile devices is committed to making their branded electronics as attractive as possible as much as possible, but some brands deliberately ignore some of the troubles of their product features. The South Korean Samsung corporation, which simply leaves the owners of many of its smartphones without the latest operating systems, likes to “sin” especially this, stopping support for such new software earlier than it could actually be done. All this is done for two reasons – not to pay extra money to developers once again, that is, we are talking about saving, and at the same time in order to motivate users about old products to go to the store for new ones and again give money for it.
Let the South Korean corporation Samsung itself make no public official statements about which smartphones will be upgraded to the Android 10 operating system, but AndroidPure, he claims, has received an official list of models that will be updated to the new OS. Absolutely all models that entered the market in 2019 will receive an update, but some models that became available in 2018 may not receive new firmware. If we talk about phones released in 2017, then none of them will receive the latest operating system at all, forever remaining on Android 9 Pie or even on an older OS, and this is of course extremely sad. 
To Android 10 will be updated models like: Galaxy S10, Galaxy S10+, Galaxy S10e, Galaxy S9, Galaxy S9+, Galaxy Note 10, Galaxy Note 10+, Galaxy Note 9, Galaxy M40, Galaxy M30, Galaxy M30s, Galaxy M20, Galaxy M10, Galaxy J8, Galaxy J6, Galaxy J6+, Galaxy J4, Galaxy J4+, Galaxy J7 Duo, Galaxy J7 2018, Galaxy J5 2018, Galaxy J3 2018, Galaxy A90 5G, Galaxy A80, Galaxy A70, Galaxy A60, Galaxy A50, Galaxy A50s, Galaxy A40, Galaxy A30, Galaxy A30s, Galaxy A20, Galaxy A20e, Galaxy A10, Galaxy A10s, Galaxy A10e, Galaxy A9 Pro 2019, Galaxy A9, Galaxy A7, Galaxy A6, Galaxy A6+, Galaxy A8, Galaxy A8 Star Lite, Galaxy A9, Galaxy A9 Star Lite. Some of these have already received a new OS, but most of these will only be updated in the next few months.
It turns out that in total Samsung plans to upgrade to Android 10 about 45 smartphone models, starting with the extremely budget and ending with many others. Also, the Galaxy Tab S5e, Galaxy Tab S4, Galaxy Tab A 2019 and Galaxy Tab A 2018 tablets will receive the update, and the owner of all the other older ones was simply left without a new operating system. It turns out that users of the Galaxy S8, Galaxy S8 +, Galaxy Note 8 and many other flagship-level electronic devices released in 2017 and earlier are forced to buy a new smartphone if there is a need for modern software. And all this despite the fact that the hardware of these models is quite capable of pulling not only this new OS, but also any subsequent ones that will enter the market in the next at least three years, and possibly longer.
