Released with Android 5.0 and runs Lineage 15.1 (Android 8.1)...not that bad for an unknown device with low sales. Most probably aren't used now or even are out of order.
You've got Jiayu S3 from Android 4.4 to 8.1 too
And you can find more
As I said devices with low sales...
And with a soc hated by part of community...
...this part often never try one. For exemple, the mt6752 in the Lenovo was far far far better than his competitor (SD615)
Always asking me why community supports and protect that much Qualcomm when this company was condamned all around the world...
This device need good sales...as it is an huge update compare to 7 Pro (officially unavailable in Europe and when 8 is a tiny update compare to 7), it deserves
And as sources are here, it need developpers support too...
Otherwise, they will give monopoly to a company known for abusing of it (courthouses decisions in China, South Korea, Taiwan, European Union, district of California...)
...a fake freedom!
No matter if it gets devs support, if it alllows B28 band, I will probably get one...
