Remember the promise? 18 months of guaranteed update and we won't forget you like other companies do. Well, they did forgot the Moto E(2015). Why am I telling this? Is this just because they weren't included for 6.0 update?No! Not at all
Although, updates remain the major parameter people are attracted towards moto series it's not the only cause. The build quality was far too much complicated in E and everything seemed to be locked down. The head along customisability for back cover was refrained. There's a pattern I have been noticing a while. Every next gen is a competition to previous gen parent. For instance, G3rd gen is competition to X2nd. The trend was also wiped from E2015. Ignoring the enormous battery, the phone was crap compared to phones with similar price tags (Redmi2, Lenovo a7000).
Conclusion
All together the phone is not entirely ignored. According to Motorola, it will continue to get updates. Not the Marshmallow, but the 5.1,5.1.1.There are few customization available and plus it ships with a incredible battery and Moto voice.
