Il 25 marzo Ulefone, ad una mia domanda riguardo l'aggiornamento del Paris a Mashmallow mi rispondeva così:
" We were supposed to release Android 6.0 this month but sorry we have to postpone it to May because MTK has slowed the Marshmallow development with MTK6753.
Sorry for keeping you wait. And don't worry. It's not marketing hype, we are doing the the optimization and it will come out."
Purtroppo, più il tempo passa e dopo quanto dichiarato per l'upgrade del Vienna, i miei dubbi sono aumentati.
