Having many problems on my NOKIA 3 / 7-1-1-nougat I have decided to test Oreo beta
After registration, I got the OTA notification for OREO beta update
It took a while to download and install the new update.
Surprise, after Oreo installation, the phone restart to the terrible Android laying down mascot with a red triangle having an exclamation mark.
The phone automatically restarts after few minutes to the same screen multiple Time
Having no idea what to do, I tried Wiping date and cache (POWER + volume UP)
Any help from the community
You can check out the Nokia 3 xda forums for possible solution. Thank you.
In this topic may find the reason of my advice. First of all, everyone who want to do un Android upgrade must had made a factory reset and then do the upgrade. Why? Because all the apps instaled by default and updates of the apps instaled by default, the apps that was instaled by the user hold of part of smartph. ROM, increase the OS and as a consequence they made, somehow, a fragmentation of Android OS. This fragmentation maybe persist after upgrade and can gave some errors.
But, as I said, its the second time that it happens. On the first time I also did a system wipe and , for almost a week everything was ok. Today , when I restart the phone, for my surprise, it happened again. Now I did a system wipe and also format the sd card. Lets see if it happens again or not. If it happens I will roll back to Nougat.
