Guys how the build 10149 running on Lumia 520?i think its very slow in low end devices. Will the coming builds make the low end devices fast?

[Zachary Boddy]

Good morning,
Build 10149 runs great on the Lumia 520. There's a good bit of lag and some stuttering but it's nothing you can't just ignore. For the most part, Build 10149 runs just as well as Windows Phone 8.1 on the Lumia 520. If you can put up with graphical glitches, UI design quirks and a generally incomplete OS, and you know how to deal with potential bugs, go for it. Build 10149 is the smoothest build yet

Are u a user of Lumia 520?

[Zachary Boddy]

Yes, I decided to install Windows 10 Mobile Insider Preview on my backup Lumia 520, and it runs fine. If you want to keep your data though, back up your phone! Remove the microSD card before installing the preview (if you have a microSD card in there). After everything has been installed completely, wait half an hour to an hour then do a hard reset. Don't do it right after.
That may have all been known to you but in case it wasn't, it's good to know.
