I have L91 version by the way if you dont even know hardware requirements then how can you say VoLTE on L91 is not supported from hardware side.Look at Soc mt6755 it supports VoLTE but still there is kind of confusion.

You can check personally with the same firmware on L & M versions, you'll come to know. I had both versions. M & L.

ye i checked friend its configuration actually flyme global firmware has a patch so called patch that makes it work in l91 model otherwise rom is completely for m91 model i doubt flyme did not add volte driver for l91 and as demand for volte grows it decided to remove volte from flyme 6 for m91 as well so everything is balanced now no volte at all xD neither for m91 nor l91 so l91 guys dont shout about volte just on m91.

Mail to meizu China your concern they will be solve it

Lets forget this thing and look forward to Charm Blue S 6 purchase

M3 Note L91 cannot support VoLTE. M3 Note M91 can as M91 also supports Chinese firmwares.

because of software difference or hardware?
