The Xiaomi Smart Kids Watch features 20MB of storage space. If your Xiaomi Smart Kids Watch is running low on storage, please refer to the following information:
1. Delete unused photos by going to the watch interface >> press and hold on the right-side button >> select Gallery >> choose photos → tap the delete icon in the top-right corner to remove them.
2. Resolve SMS-related low storage alerts: If you receive a “storage full” SMS warning, please back up important data first, then unpair the watch on the Xiaomi Kids App ([My] >> [Watch management] >> [Unpair]) and then reconnect it.
