Xiaomi Redmi A1+ - budget smartphone with Android Go system. The smartphone has a slot for placing an additional memory card, through which we can add a separate memory in case the smartphone's memory is insufficient, where it will be possible to transfer or directly store images, music, videos, movies, etc. Despite the pure Android system, in the smartphone we will find such a feature characteristic of MIUI as Memory Extension, but unlike the Memory Extension of the MIUI system, in the existing smartphone we have the opportunity to increase the RAM by 0.5 GB, 1 GB, or 2 GB, which It allows us to accommodate much more tasks and ensures that they are completed relatively quickly.
