Android gripe: internal storage

[mtbc]

My cellphone is a Moto E, new enough that I've not yet reached the point in the contract where they offer a free replacement. Since the upgrade to Android Lollipop routine app updates frequently fail through lack of storage. Vanishingly little on the cellphone is anything that I have installed or otherwise caused myself: I'd guess that 80% of the internal storage is taken up by system apps (and updates thereto) that cannot be moved to the SD card. Color me unimpressed.

I usually don't at all get on with modern consumer-friendly GUIs but Android has been a pleasant surprise in that respect. I don't know if I just have to be resigned to choosing a devil-I-know Android cellphone next time with a lot of internal storage or if competing operating systems might be similarly usable yet less storage-hungry.
