I am now using the Xiaomi Mi4i and I am not very satisfied with it. The phone has too many small bugs and MIUI is not very appealing to me. I am looking for a new phone with budget max 25k. My number one priority is stability. Would prefer a phone that has active ROM development community and Nexus 6 seems to have a great community. The Pure Nexus ROM seems to be a stable and hassle free rom. Is it wise to go for an older model? Is 20k too much for 18 month old phone? Will this phone last two years?
