[YotaPhone 3 Questions & Answers] jan.nowak:
I bought of Yotaphone 3 from CECT Shop in GB so I could share some of my new gained experiences.

CECT Shop offers CN version, with Android Nougat 7.1.1, China and English language, build in 64GB storage, without Google Services and tons of CN apps.

Implementation of Google on Yota3:

Absence of Google isn't real problem. You could without and dificulties download 4 needed APK's from "external" APK repositories like APKMirror. You need to install 4 apps in exact order: Google Framework (look for 7.1.1 version), Google Play Services, Google Account Manager (look for 7.1.1 version too) and Google PlayStore (you should use NODPI versions) . It's important not to run any of apps until full install procedure. After install you should reboot your phone to allow adding new Google account.

About Android and Yota optimization mechanisms:

For start lets agree that Android 7.1.1 itself have in opinion of many users some real "issues" witch optimization procedures and DOZE. Google assumed that running some sort of apps in background isn't much high priority for system, memory and battery drain (not 100% true). You may be shocked, but one of these apps is for example Gmail, bunch of similar apps using push communications/notifications, and lots of more useful software. On top of it is fact that on Yota3 is large number of, lets say, "hard coded" CN system apps. Apps that (it's my opinion based on my observations) partly trying to replace original Android 7.1.1 functionalities, like mentioned before battery optimization and permissions management. In result original Android possibility of disabling some of these mechanisms just doesn't work (excluding apps form optimization works for at most until the phone restart). When you connect need of constant excluding apps from optimization, and fact that even those smallest like Clock need to do that for proper work, then you realize that it's real pain in the @$$. But there almost always some way... For consolation, if you reduce amount of apps that must run in background (I have about 15 of all of my 70-80 apps set so) you could live with that and have a chance for nice and fully functional phone.

Other disadvantages:

1.	Low functionality of back E-Ink screen. Most of apps able to run on it is CN apps like: CN eReaders, CN news and weather apps, CN music player, etc. For now (I hope temporary) there is no possibility to mirror/transfer view of front screen to back screen. :(

2.	Notification from regular not CN apps doesn't display either on front lock screen and back E-Ink screen.

3.	On one hand fingers you can count apps designed and working on back E-Ink screen available in PlayStore.

4.	For now there is no possibility of root implementation.

5.	For now there is no custom ROM available for Y3.

6.	Y3 doesn't have NFC for contactless payments.

7.	Y3 doesn't have backlight for E-Ink display.

Benefits:

1.	It's great phone with nice big Super AMOLED screen.

2.	It have dual SIM slot and 4GB RAM.

3.	Y3 is super thin for phone with 2 screens. You look at it and wonder where they have put and fit 3300mAh battery in it?

4.	Running time on 3300mAh is pretty good.

5.	Nice 3A charger.

6.	Rubber-like cover case.

That's for now...
