I've had my Blu Life pure XL still running Jelly Bean. Still fast as fukk, why?!?! because it doesnt have Bulltshyt software. bloatware or something slowing the phone down. If your Samsung phones have problems just Root the damned thing, take out the unneccesary shyt and rock with that. I dont know why people have problems with android shyt is SO easy.
Iphone tends to get on my nerves with the music aspect your FORCED to use Itunes no matter what,

You cant play MP3's freely without it or somebullshyt. I had a 4s and I swear shyt was annoying.
And now my Blu I just have google drive / Google docs, I send all my pics / docs back and forth and shyt works like a stallion, anything i need printed or modified I change on the fly or at home no problem.
