I'm not sure I understand the world wide support, ASS is arguably the worst thing that you can say about OPO, if you are talking about XDA support, I think what's holding back support is lack of release of kernel sources, but Xiaomi seems to be on the right track, just check redmi subforum, they have a plethora of options now with different kernels, custom roms etc, so if Xiaomi keeps the promise of releasing kernel within 3 months of a device release in India, we can expect the same for mi4
How is 820 better, it has micro sd support alongside lte, what else I don't think 615 beats 801, but yeah in regular usage scenario it might not make much difference, but apart from that , I cant see much
If you are looking for that I would say honor 6 is better
specs arent everything atleast once its in that category of hardware,its the overall experience and i personally feel xiaomi's look feel and touch screen arent upto the mark
this is my observation,may not be applicable for everyone
HTC 820 can pass as a 40k phone in terms of looks,display etc and performance is great
HTC after sales and quality is also arguably better than xiaomi
MIUI is kinda bloated imho,atleast from what i have seen on the mi3 and redmi 1s,OPO with CM is the best android implementation ive seen
this is coming from someone who prefers ipads as tablets and windows phone as choice of phone despite having a Nexus 5 and Nexus 7(2012) as backups in his bag
Sense UI is not as good as CM or stock android but its the next best thing
