By my experience don't think that we have low speed ram here ! I bought my prime 6 at the end of July in 2015 and with all my stuff in it ( at the time nobody knew how to root it ) and Vodafone and also Google's the phone was relatively quick . But after some updates the performance just went down the pipe .
I think that I'm not the only one here with the same opinion !
If we could have in our hand the stock ROM that came with the phone WITHOUT the updates you would understand what I'm saying now .
Vodafone killed the usability of the phone , the multitasking now is super sluggish ( even after I super cleaned up the stock ROM by tripping all the Vodafone crap and Google's too, tweaked the kernel and using Xposed modules to speed up and stop certain system apps from running or scanning during normal use ). It didn't matter what I did ....
