I am experiencing a problem with this developers preview.... My phone was okay after update.... Was running smooth and nice but some time it takes time to start some apps so I reset my phone... but sadly my real problems started after reset... My download restriction reduced to 20mb... I tried everything to fix it but sadly nothing won't work... Do you have any suggestion for that?? I am using a Lumia 620 and I am from India... Any answers will be appreciated...... Thanks for reading.....
