    what should i do ??

    Backup and use Windows Device Recovery Tool to roll back to windows 8.1 Denim log in to your accounts and then choose insider preview fast ring update it back to windows 10 build 10586.71 that build has lots of fix and everything works perfect on my Lumia 640XL

    Build 10568.11, Anyone? Lumia 640XL Dual SIM

    Everything works except my Outlook Mail app it opens but I just cant add my account so I have lost all my contacts. Supposing I was able to synchronise I will gain my contacts back. it's a technical previews so at least you will face problems.

    How much free space is needed to install build 10586?

    1.50GB would do. So you have to make backup and transfer your apps to your SD Card
