 **Notable features:**
-  * Can **record phone calls**. Enable the feature from //Settings//=> //Auxiliary function// => //Call recording//.
+  * The phone is **waterproof** at least to heavy rain. I used it as a GPS navigation system mounted on a motorbike during a huge rain storm for about two hours, without any problem.
+  * It can **record phone calls**. Enable the feature from //Settings//=> //Auxiliary function// => //Call recording//.
   * Blue/red **LED** for notifications and charging.
   * The **FM Radio is non functional** because there is no 3.5 mm socket and it is not possible to connect the earphones cable.
-  * **Aggressive power saving** kills background apps. Widgets in several apps have trouble initializing themself after reboot; may stop working or may not update contents. Exposed settings (permissions, //pause app// if unused, //unrestricted// battery, //battery manager//. etc.) are not sufficient to overcome the problem. Internet syncs and notifications of less-known apps are lagging or stopped.
+  * **Aggressive power saving** kills background apps, i.e. apps are automatically cleaned from the recents.

Beside the settings available in //Apps & notifications// (permissions, //pause app// if unused, //unrestricted// battery, //battery manager//. etc.) there is a custom app called **System Manager** which may solve the issues; see **[[blackview_power_saving]]**.
+  * **No system updates** available: in September 2024 it is still stuck to Android 13, security update September 5, 2023.

 ===== Power saving =====
-FIXME On this smartphone the battery and power management operated by the Android o.s. is very aggressive. There are several settings that can be adjusted, but it seems that some apps and widgets does not run as expected.
+On this smartphone the battery and power management operated by the Android o.s. is very aggressive. There are several settings that can be adjusted:
   * **Battery Manager** (system setting): Settings => Battery => Battery Manager => **Manage apps automatically**.
@@ Line 394: / Line 395: @@
   * **Pause app if unused** (per-app setting): Settings => Apps & notifications => App info => App permissions => **Pause app activity if unused**.
   * **Battery** (per-app setting): Settings => Apps & notifications => App info => Battery => **Unrestricted**, **Optimized** or **Restricted**.
+Other important settings can be operated into the custom **System Manager** app. See the page **[[blackview_power_saving]]**, it is about the customization made by Blackview on the Android operating system regarding several **power saving features**. It applies on both Android 12 and Android 13 versions.
+===== Storage (problem with widgets and SD card) =====
+When you add an **SD card** to the smartphone, you can use it as:
+^ Portable storage               | You can save files, like photos and videos, on the SD card.\\ You can’t install apps on the SD card.\\ You can transfer the SD card between devices.  |
+^ Adoptable or Internal storage  | You can load files, like photos and videos, on the SD card.\\ You can install apps on the SD card.\\ You can’t transfer the SD card between devices.\\ The SD card can be used in addition to your device's storage.  |
+If you use the SD card as internal storage all the **compatible apps** will be moved to that storage (if you tell so) and new installed apps will follow the same destination. You can check if an app is installed into the SD by tapping **Settings** => **Storage** => **SD card** => **Apps** => (select the app) => **Storage used**. In this menu you can tap the **CHANGE** button to move the app into the other storage.
+I found a problem on my Blackview BV5300 Pro, because some apps installed into the SD card were not seen as **widget providers**, i.e. **I was not able to add the widget on the home screen**, just because the app was not shown into the list. Moving the app to the internal storage, the problem was resolved.
+===== Wallpaper scrolling effect =====
+It is possibile to have a **wallpaper with scrolling effect**. This requires a wallpaper picture which is wider than the physical screen; when you **swipe** left or right through the **home screens**, the wallpaper picture scrolls (pan) left or right too. To get such effect, you have to set the wallpaper using an app (e.g. with [[https://f-droid.org/en/packages/org.fossify.gallery/|Fossify Gallery]], long-tapping over an image). If you set the wallpaper with the launcher app (the stock BVLauncher or the alternative Lawnchair) the scrolling effetc will not be enabled.
+===== Changing the default launcher BvLauncher =====
+See the page **[[blackview_bv5300_pro_change_launcher]]**, it is about the installation of a **custom launcher** and removing **unnecessary system apps** (de-bloating).
