Buyers needing 5G or a glass back should look

The handset supports GSM, HSPA and LTE bands 1, 2, 3, 4, 5, 7, 8, 20, 28, 38, 40 and 41 but lacks 5G connectivity. Its hybrid Dual SIM tray shares the second slot with a microSDXC card. The plastic back and IP53 rating offer only splash resistance. Users who want 5G speeds or a premium glass build will need a different device.

Qualcomm Snapdragon 860 powers the phone with an octa-core CPU reaching 2.96 GHz and Adreno 640 graphics. Eight gigabytes of RAM pair with 256 GB of UFS 3.1 internal storage.

Questions about this item

How do I insert the two Nano-SIM cards and a microSDXC card into the hybrid tray without losing the second SIM?

The hybrid tray accepts either two Nano-SIMs or one Nano-SIM plus one microSDXC card; you cannot use both SIM slots and the memory card at the same time.

What part will need replacement first if I keep the phone for several years?

The sealed lithium-polymer battery is not user-replaceable; its capacity will degrade with charge cycles and eventually require professional service.

Which hardware limit appears first during long gaming sessions on the Snapdragon 860 with Adreno 640 graphics?

Sustained load causes thermal throttling as the plastic back and mid-frame limit heat dissipation, reducing CPU and GPU clocks after extended use.
