Thanks for your contribution. I understand it may sound silly to make a decision based on the notification LED, but it's one of the few features I care about. I have a Redmi 2 now (4.7'', Snapdragon 410, 2200mAh, RGB LED, Dual SIM + microSD) and I am perfectly happy with it, if not for the smashed glass.
I have low, but hard to match expectations for a phone: cheap, small, usable (not TOO slow), RGB LED, Dual SIM+mSD. So size does matter, in fact I wish I could find a 4'' device with barely decent specs, but the market clearly went in the opposite direction (and I'm not getting an iPhone SE). Also, if I am not wrong the Redmi 5 series has a monochrome LED, so I would lose too many of the features I want.
The Redmi 4A would barely feel like an improvement over my current phone, but at least I would retain the RGB LED and the non-outrageous size. If you can think of an alternative that better matches my expectations, I am all ears!
Sorry about the OT/blurb. :silly:
