Network.
This product is good and supports volte but sometimes it has issues of frequent network disconnections and also auto switch off of phone I am using this since last 2 months and this is my true experience
Customer service .
Customer service is bad as there are very few service centres and they also take a lot of time to do nessesary adding to your faulty phone apart from this they sometime easily deny to do your service and this is a bad experience
Screen and overall performance .
Performance wise phone is good and runs smoothly.
