Hi bro, I was glad I left Z2. I had a super bad time with Sony. I had lost my trust. I had changed 7-8 sets. What was the reason? Phone with dents, paint drops, bright stuck pxiels, dead pixels and worst of all self operating. My final set which I thought I got finally settle down with the Z2 when it started to operating on its own. My final set had its screen replaced instead as I had decline for a new sets after changing 7 sets in total.
The phone would enter apps, scroll through the apps, open the music player, play the songs, change the songs, go to homescreen, turn on youtube, play videos. I not even touching it. I guess the screen had some issues. Even when my finger was hovering like 1-2cm above, the screen would appeared to be touched. Sony stuff initially say its was the metal bumper that I used but I told them that the demo set at the service centre actually had it but just that no one make noise about it. My friend was with me and he was my witness by taking videos of the demo set. I went to this extend as the Sony stuff kept saying I'm the first to experience this issues. Even my friend who got a Z2 do have the stuck pixels. But he is ok with it. I guess this is individual preference. But he may plan to send it in if it get worst.
I spend every weekend at the service centre and rushing there during weekdays after work. I had already make friends with the people there, haha

I given up, full refund was finally settled.
I do agree that the LG lazer thingy do get scratched easily. I have send an email to LG, see how they respond. This G3 is also my first phone from LG and the Z2 was also my first Sony phone. Overall, I would go over to LG from the bad experience with Sony.
