Shashwat.newk1995, 14 Jul 2016Anyone who was using win10 in this device and roll back to 8.1?? How was your experience? Tell... moreI "upgraded" to W10 on this phone and it's my strong recommendation to not do it. It was a nightmare. First, it lost all my contacts during the upgrade even though, at one point, it said it was transferring data. I freaked out at first, but was glad to find they were backed up in cloud. Then, once W10, all app icons were more closely crammed together than before. I also found it very difficult to navigate the settings. A tone I liked to use for recognizing one of my email accounts was replaced by another. All other tones remained. Some others were new. Also, I hated the email list layout. Just awful. Small text for the subject line. Was almost indistinguishable from other messages. I tried for about a week to get used to it, but I couldn't. Reverted back to 8.1 (surprised but glad they let you) and am happy again. Don't upgrade to Windows 10 Mobile, and don't buy a phone that might already have it installed!!
Anyone who was using win10 in this device and roll back to 8.1?? How was your experience? Tell me about battery backup, heating issues and faster app opening.
Shashwat.newk1995, 13 Jul 2016No more time left. Msft sold their hardware unit to Foxconn and closed Finland Nokia unit. Now... moreI still believe MS will do otherwise and leave the hardware stuff to OEM like Acatel or HTC. Anyway I think they will continue to release a good charming Surface phone next year. Keep waiting.
After long Android experience, I've had this 640 for a month and I tell you I was surprised, it's a great phone. Camera is great, smooth performance, battery lasted amazingly over three days at normal use. App-store has everything. And man I love those active tiles.

Msft sold their hardware unit to Foxconn and closed Finland Nokia unit. Now they are behind surface phone whose os will be different than Lumia. Now you can calculate how much time left.
Moving from Android Marshmallow, I found this phone have great apps organised, stable and didn't take much time to learn settings, especially when it runs windows 10. Battery is up to 2 days for medium use. Windows 10 is not matured but it will get there soon. My really question is how long Microsoft will continue to support this phone since I really like it.

I used Android for two years then tried windows and found it a lot cooler, smoother, and more organised. This 640 seems to be one of the best Lumias available at a great price/quality ratio. I'd give it 5 stars without any hesitation.

This phone is the best phone ever. I've tried win 8 and win 10 both on this phone, upgrade and rollback, but no serious issue at all. Just some bugs that caused by developer. The battery is not bad. I love this phone so much!!
