I recommend waiting for the final non-preview version.
Yes very stable
Just as the post suggests I am wondering should I use the insider app to download/upgrade my Lumia 640XL to windows 10? Is the current build really stable??
I had what I thought was a stable build on my old Lumia 520 and it broke my heart. Very laggy and had it out of my phone after it was in only a week.
No, it was not stable at all when I have tried few weeks ago, Have to reverse to 8.1
Works very well on my 720 with some minkr lags and stuttering.. It would work on 640xl pretty smooth.. 520 is the most low end device so it will perform worse.. Watch 640xl videos on youtube running 512 amd decide whether to install or not..![]()
10512What's the latest build number I should look out for in case I decide later to upgrade?
A mixed bag of reviews I suppose the only way to know is to upgrade foe myself and see. But omg I know from experience that ill have to downgrade again. Thanks so much everyone for your feedback.
Never know, you might like it. I also am running 512 on my icon with good results. Most irritating to me is lock screen information lagging.. Small glitches here and there.. Big improvement on battery life. Be sure to hard reset as suggested in above posts..
