Damn it, i cant get my LIVE wallpaper to work.

Already try restart, change to STILL then change back to LIVE wallpaper, also try adjusting the 3D touch. 

I have chance to test iPhone X over the weekend on highway. Literally testing how good 2nd gen Intel modem is over my bad experience for the 1st gen in 7+. It is imperfect, I was asked to turn on the straight road of highway few occasions, was thinking my car in another direction when I was not moving, response was slow update after i have move out from that location, in general I don't see this in 6s+ or 6+ with Qualcomm. Sorry to say, the engineers never learnt!

I also have weird focus with 'water bubble' image on portrait front mode when it can't focus, the picture will be taken as water bubble if it is not rectify with touch to focus on the image it was trying to focus.

The former is more concern to me who really care how accurate GPS should be, sad. Will try on my iPad Pro Qualcomm GPS when there is a chance.

Dang, my iphone just got bricked. I tried to update latest firmware by restoring in iTunes. Got stuck at error 53. Can't find any info on the internet. I've spent around 6 hours trying to get it to work but still can't. FML.
