how to get android 7.0 nougat installed again in place of updated pie 9.0?

[unnu1234]

All users of samsung j7 pro have found that their phones (j7 pro) have become slow and lagging in games , also more battery is used even for small tasks after software update from android 7.0 (nougat ) to the following android 8.0 (oreo) and 9.0(pie) as compared to the usage experienced on original nougat 7.0  , this means that developers of android as well as the samsung android developer team have not paid attention to the performance loss and battery problems arising due to (faulty) android updates , why has this happened ? , did the developer teams not know that samsung j7 pro has only 3 gb ram , why have they made us update from perfectly fine nougat 7.0 to useless android 8.0 and 9.0 os , this is very bad for the phone and its users. Even camera performance has suffered after updates...... samsung please do something , even iphones have only 3 gb ram but they dont lag , so why should our phones lag ? 

Please correct the ram management part of the android os so that we get good performance even when using android 9.0 pie.

It is my request to the samsung android os developer team to release a corrective update for android 9.0 updated phones like samsung j7 pro as well as other j7 series phones for better performance as well as better network reception
