Big lie. I upgraded my htc one m8 to android 6 a week after I bought and it was really wonderful. Maybe android 6 slacks on your phone that is why you think it should be the same on everyone's phone. Ignore joor.

Hey bro, i'm planning to buy that m8( fairly used tho) before the year runs out.
What do you think about its Camera, battery life, over heating, memory space, unremovable battery, nano sim etc.
Generally, whats your advice and what should I look out for? Any pros and cons??

Camera, battery life, over heating, memory space, unremovable battery, nano sim. These are not issues at all. The phone is an excellent phone. Just get the phone along with the dot view cover. Google it if you don't know what it is. Then you've got yourself a wonderful that would make people jealous. Try upgrading it to android 6 if you eventually buy it. It would be much better. I also want to tell you that I got mine for 50k and the dot view cover for 2k. Sometime in April.

get the phone.

I upgraded to Marshmallow 6 on my Gionee M5 Mini, but lost my rooting which I have not been able to re-do with Kingroot or some of the popular rooting apps.

Please I need the genius in the NL to offer me a helping hand as to instructions for re-rooting (as I am already missing the "sweetness" of my machine).

Thank you and be blessed today!
