Hello,
Based in France, I also bought the Nova 4e with Chinese android that is blocking most of Google apps, I couldn't even use Deezer and Whatsapp at the begining.
I have been trying all the possible scenarios that I found online, when arriving at the point of installing and launching the Google play store app (any version), the app was crashing and the phone was then becoming really unstable.
the only option I finally found, is to press *#*#2846579#*#* and do a factory reset, then restarting the phone and choosing to clone with my previous android phone (HTC desire 10 pro), after doing that download and install only these 3 APK of (reminder: at this stage you have to download APK files to install apps, from your phone directly or from a PC):
Google Account Manager.
Google Services Framework.
Google Play Services.
DON'T INSTALL GOOGLE PLAY STORE!
You can use APK Pure that is a neutral play store where you can download all popular apps just like on the classical google play store.
If you have a Gmail email box, you can use the Huawei email app that is really good or use a great alternative named myMail.
To substitute Google map you can use Waze or Here WeGo, as you need to log in with your Google account to use YouTube you can use as a substitute: Play tube app.
Google chrome is working so you can also use some Google apps like Google drive, Gmail , you tube or Google agenda from chrome.
All the other apps work fine, Facebook, instagram.... actually being in such situation make you think that Google is really everywhere in your phone and make you think differently forcing you to search for alternatives.
I bought this phone on a Chinese website, in the item description it was written "Huawei P30 Lite Nova 4E" actually if you encounter the same problem as me and you have received a NOVA 4E the seller is wrong and if you open a dispute with reason "parameter not as described" the seller will probably refused to refund but then the website should intervene and say you are right, in my case they offered me the solution below:
Option 1: Return goods Full refund (Seller pays the returning shipping fee)
I think that I will keep the phone, I will probably try to root it but It seems the bootloader code for this phone is not available at the moment, some people even say there is no code for this phone so I don't really know how to root it.
If somebody manage to do it I would be interested to have the procedure.
