As we continue to get more info about Windows 10 for Phones some users had the mixed feeling of receiving the update for their 512 MB device, specially Lumia 635. Even though there are confirmations that Lumia 520 being the most low end device will get Windows 10 the probability of it working super smooth is a setback.

Latest tweet from Gabriel Aul states Lumia 635 is one of the low end devices carrying Windows 10 beautifully this also being a quad-core processor device has an added advantage over the dual-core ones. The only concern is that 512MB devices wont support all Windows 10 features puts us in a fix assuming these features are totally dependent of amount of RAM required to process some functions or the hardware really doesn’t support.
In other news still waiting for the update, the Spanish version of Insider app gave away a different link to the preview FAQ here. The link, as expected leads to nothing but it could be a hint that the preview is close, probably few more hours?
