We do not recommend using portable external hard drives (StoreJet) on smartphones/tablets for the following reasons.
1. Smartphones/tablets may not be able to provide a stable and sufficient power supply for the portable external hard drives (StoreJet). An insufficient power supply for a long time may lead to damaged data.
2. The portable external hard drives (StoreJet) apply to Windows/macOS, and there is no guarantee that they work on the Android system. If you use a mobile phone with USB Type-C, we recommend using portable SSDs or mobile storage for Android devices. The product links are as follows:
