Anyone who has submitted their 6z with the service center for the auto restart or bootloop. I've been told by the service center guys that the problem is with the motherboard and they've replaced it. But still the problem is showing up. Now they said the bootloop issue is still coming up when the camera is used for 5 and more times and they've changed the camera assembly. Still the problem is showing up. They're not able to rectify the problem and said ASUS has sent them all parts and they'll replace one by one every part and try to rectify the problem. They haven't even updated the RMA to track the repair my phone is lying in the service center for last 1 month. Seriously ASUS this is how you treat a new phone by replacing it with every new part. Why not give me a new phone or a refund. I'm fed up with the service of ASUS!!!
