I have a few questions, first, which company makes the devices you're having issues with? HTC, Samsung, Motorolla? Second, which carrier? I haven't had an issue (that I haven't caused) with Android, and I've had them since my G1. Not to say I don't like my Lumia, just as a point, none of my Androids have had any of these issues. I have done a lot of custom ROMs, and haven't had lag or anything, and have stock on my S4, with XPosed modules to customize it, and Titanium Backup because who wants to be forced to have Trip Advisor.
I'm tempted to call this a FUD-like post to be honest, as I don't see anything specific here. Do you think if your issues were widespread, people would continue to use Android? I mean, lag, sure, it *can* happen, but there's cache cleaners. But, the data connection issues, I don't think anyone would use it if that happened.
I like Android because it feels more like a computer in my pocket, as I can tweak whatever I want. I like WP because it isn't like a computer, it's a smart phone. Never had to go w/o my Lumia working because I tweaked it, but I have had to hobble along without my GS4 because I forgot not to mess with my EFS partition.
Edited for clarity.
