 ,9% of these users are owners of **Xiaomi** or **Huawei/Honor** phones and tablets. The most probable cause of disappearing Locus data in these devices is a very **aggressive memory cleaning software**, part of MIUI or EMUI operating platforms running on these devices.

 **Exclude Locus Map from memory cleaning**. When your Xiaomi or Huawei alerts you that they desperately need memory cleaning, please, be careful. In some devices/OS versions, it is possible to exclude Locus Map from memory cleaning:

+===== Malfunction of the SD card =====
+Many users still use the external SD card as the storage for the main directory of Locus Map. As we [[locus_on_external_sdcard#all_locus_map_s_data_on_the_external_sd_card_-_not_recommended|mentioned elsewhere]], the **SD card is not suitable** for it because of the app's random read/write access to the main database. The SD card is not constructed for this, and it may result in damaging the database. And even the **slightest change to the database may result in its unavailability**.
+==== Solution ====
+**Don't use the external SD card for the main Locus directory**. Use it for maps, elevation or geocaching data but **keep the main directory in the internal storage**.

 ===== Uninstallation or factory reset =====

 ===== System-forced change of default app's working directory =====
-With the arrival of Android 11 Locus Map lost the option to have its working directory in the root of the internal or external storage and was forced to [[https://www.locusmap.app/android-11-brings-a-major-change-to-locus-directories/|use the private sector in /Android/data/ directory]]. Immediately after the change, we introduced an optional **[[manual:faq:android_11_filesystem|simple data transfer]]** which was available to Locus Map users for a temporary period. **The period has now expired and the newest Android OS versions automatically change the path to the Locus Map default directory WITHOUT WARNING**.
