Still b/o for me ๐Ÿค”
Well, my order from 4/15 still on b/o as of today. Hoping for any cell connectivity since the band 4 "disappeared" from earlier announcements! I travel a lot so should be good in row.

Currently running row ROM on nvidia shield tablet but battery life has become terrible in the last few updates. At least it gets hspa+ in USA and LTE elsewhere on the planet. And the big + was never had to wait on ATT to bless an update!

Going to use this Chuwi to replace a pipo m6 pro w/custom rom Itravel with.

Let us know all about it as soon as you get it!

Edit: Now they say shipping 5/15.....maybe I should get interest on the cash I gave them 4/15.....๐Ÿ˜‚๐Ÿ˜‚๐Ÿ˜‚
Will hold tight. I have time to cancel if the first hands on reviews are terrible!
