Malas noticias para todos. Lollipop nunca llegara al UMI emax. Esto dice uno de los moderadores en el foro oficial de UMI.
Now I must say that's better not to expect the lollipop upgrade for eMAX. That's still possible but not promised anymore.
We know that, this model is developed and made by TCL. UMI eMAX is a slightly modified version of TCL M2M. What we can suspect, UMI probably contracted with TCL to develop and manufacture this phone with installed Android KitKat but they haven't negotiated about a future lollipop upgrade. TCL was not willing to build that lollipop firmware or asked for a too high price, so some UMI developers tried to create that firmware by their own but they have failed. The third participant in this story is MediaTek, the developer of the MT6752 SoC built in the eMAX. Gossips say that, MTK refuses to provide the lollipop source code for this SoC (as well as for MT6592 too). That might be true since (for example) two flagship models of some major brands with MT6752 SoC, Meizu M1 Note and Jiayu S3 still come out from the box with KitKat, no official and final lollipop upgrades are known.
UMI probably trusted his developers and business partners overly, that finally made them not to be able to abide their promise.
As a conclusion, I can suggest everybody who can't live without lollipop to sell their eMAX and buy another phone. All the others - who still love this anyway great device - might continue using it until the next change that's justifiable by upgraded hardware or new features.
Para quien no quiera leer, lo que viene a decir, es que no se espera que llegue Lollipop, dado que TCL (que es quien monta realmente el UMI Emax) no va a dar su Lollipop desarrollado y los desarrolladores de UMI no son capaces de hacerlo. Así que mala suerte a los que teníamos puesto ilusiones en ello.
