+====== SD card limitations ======
 Many devices have microSD card slots with artificially limited specifications or capabilities. In some of these devices, users have successfully worked around the artificial limitations.
@@ Line 5: / Line 6: @@
 Devices with microSDHC card slots are usually only officially rated for cards up to 32GB in size. However, this is often taken from the [[wp>SHDC|microSDHC specification]], and not the actual capabilities of the hardware. On some models, users have achieved success with larger SD cards.

 ===== Adoptable storage =====
+<note warning>
+**PLEASE READ** \\ \\
+Adoptable storage has been found to cause bootloops in MANY scenarios. At this time we do not know what causes it to happen as adoptable storage seems to work perfectly fine on some phones. This seems to stop usually if the card is removed, however it seems that this issue can persist afterwards.
+This process can potentially brick your phone, please know that going through with this is for testing purposes alone.
+</note>
 When an SD card is inserted into an Android phone, a notification or dialogue will appear to format the card. Kyocera's Settings app only exposes the ability to format the card as portable, or external storage. Portable storage can only be used for photos, videos, and other files, and is readable by other devices.

 === Bootlooping ===
-There seems to be an issue with using the SD Card that can occasionally cause bootlooping. It is unknown what causes it at this time. It is recommended to reach out for assistance on our [[https://discord.gg/hSUkk3NYZe|Discord]]/[[https://matrix.to/#/!FQmjMYssKikhnrGlZY:matrix.org?via=matrix.org|Matrix]].
+There seems to be an issue with using the SD Card that can occasionally cause bootlooping. The bootlooping does not always stop after removing the SD card. One user was not able to stop two separate [[phones:kyocera_gratina_kyf42]] devices from bootlooping by removing the SD card.
+You may need to get the phone to forget the SD card in the [[android_settings_menu|]] in order to reformat it.
