In this article, we will look at all the current transfer methods, from standard MIUI tools to hidden functions and bypass system limitations. We will focus on storage optimization: how to make sure that new photos are automatically saved to the map and old ones do not take up space in internal memory.
Important: The instructions are relevant for all modern Xiaomi, Redmi and POCO devices based on MIUI 14/15 (including Xiaomi 13T, Redmi Note 13 Pro and POCO F5). For older models (up to MIUI 12) additional steps may be required β these will also be mentioned.
