Basically, and I'll make this short so I don't ramble, if this is a side/wifi phone where all I need it for is gaming and music, does upgrading bring anything that people 'cant live without', or is staying with an older version that has had more time to be customized a better option? I'm on Pie right now, but it's one of those things I really can't tell without setting aside time to test/experiment and focus, which I haven't ;p
Compared to nougat, the custom rom status of Oreo and Pie is miles ahead and better.....yes, there are some bugs here and there but those are minors and won't hinder your day to day usage and not to mention that even some of those bugs are being fixed and will be ironed out in the next few months of update.....recently the camera issues has been rectified and by the next updates, the camera should work flawlessly without any crashes.....even GCAM is working perfectly on the rom.....try Pixel Experience if you want, updates normally come on a monthly basis and the latest camera build prop fix posted at Pg 60-62 fixes many camera crashes.....
The only bugs which are left are normally based on the rom and its sources and normally gets fixed in the next update
.
Yes,4k recording still now doesn't work in footej camera or in Gcam, but if you really need 4k recording,use the Filmic Pro camera, it will allow you to record at 4k with variable frame rates.
In terms of performance,there are some internal improvements but for day to day scenario it is more than enough, in short you\ll be able to play PUBG at low/medium settings at 30 fps ......
What we really need is a kernel developer who can make some good custom kernels which will help in performance improvements and increase overall stability and feature array across the board....
So, in short the custom rom status is better than ever for le 2, right now ..... and this is coming from a guy who was there from the beginning when CodeWorkz was developing the nougat rom for the device....
