Still b/o for me ?

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.....???
Will hold tight. I have time to cancel if the first hands on reviews are terrible!

Hi! I just started looking into Chuwi products. I'm anxious to hear your review of the Hi9! I also would like to know why did you choose the Hi9 and not the Hi10?

Thank you!

Thank you!

Hi, I’m still running some benchmarks, I will post a review soon.
One important point to note, this is the Chuwi Hi9 Air not Hi9. Big difference!

Well, if I should ever receive mine I am glad to see they may update a few things! Ordered 4/15 still not shipped. Thanks much for your unboxing on YT. Hopefully the updates won't disable any wifi or cellular bands!

You say in the video that there will be no custom rom flashing due to A-Only, how does that correspond with the fact that A-only system.imgs are available?
AOSP: [https://forum.xda-developers.com/pr...development/experimental-phh-treble-t3709659] RR: [https://forum.xda-developers.com/pr...pment/resurrection-remix-phh-treble-t3767688]

And is the Android Security Patch updated in the new OTA?

I checked, all the bands are still there! The LTE is apparently up to cat 6.
