Thanks for the detailed description. Thought to summarize the Memory Management bug/issue current status (which is now more positive as of today):
1 Not all users are reporting the problem. However, complaints are growing in the Moto Owner's forum. Over there official Moto agents can provide their feedback and update concerned consumers.
2 Given the rather glowing reviews and online user comment/ratings its been puzzling why some folks love the new Moto G and others hate it.
One theory has been new buyers are quick to report the truly awesomeness of the phone and only later after 2 weeks of routine use realize there is a performance bug that builds overtime. After which they rarely go back to update their early reviews.
Or maybe it's just denial and of course, it could be a bad batch of phones off the production line too. Its basically not clear here.
3 There are a couple of workarounds. One is to install a custom ROM/root. Another is to only allow 4 background processes to be stored (its within Developer Options menu so no root is needed). Turning this option on results in less ram being taken up which eases the pain a bit but does not solve it.
4 For the past three months, affected users have been especially frustrated because Moto agents had not been responding to user complaints quickly.
As the Moto agents were silent and some loyal customers protested. Some folks even got rid of their devices and just elected to jump brands.
5 Today a Moto agent finally communicated that Moto is looking into the user bug reports. While the fact that there appears to be a software bug was not confirmed by Moto, it was clear the reports are now being reviewed and its being factored into Android L new deployments.
In short, it looks like the issue is being treated seriously by Moto agents. And if there is a way to fix it via software updates, it will be done so via Android L.
How and when is not clear yet. But you can bet users will continue to track and maybe lose some patience if Moto ends up needing a lot more time.
