Honor 6x just bought it few weeks ago from amazon. Its working preety good no lagging(as it come with 3GB and 4GB RAM variant), no heating problem, Good dual camera(12 AND 8 MP), good build quality(gives you premium felling), good battery life 3340mAh(lasts whole day while playing games surfing internet), Accurate fingerprint sensor.
But the SIM slot is Hybrid meaning you cannot use 2 Sim card and a memory card all 3 at a time .its either 2 Sim card, no memory card or 1 sim card and 1 memory card. ALSO the low light camera performance is just average
