I hope this email get to the attention of the decision makers . I was excited when I bought my first Lumia 520 Lumia 640 extra large because I was in love with the brand Nokia and I thought wow when Microsoft is taking over as it is a formidable brand . But to my dismay the both of in terms of smooth functionality couldn,t last even up to a year both of them are giving me problem .The 520 is very difficult to charge it it run for ages. With my Lumia 640 now its more than a year but it is giving me problems I can,t access my calendar I cant take photos or vidoes yet its not yet two years. Of late I can get calls I just see notification from the airtime
After my XPERIA Z1 died, I had a choice between Galaxy S3 for the same price as this Lumia 640LTE, I went with 640 without no regret. Latest OS version(Entered preview ring on windows 10 insider program), smooth performance, long battery life.
Acquired this phone few days ago, Windows 10 Mobile works smooth on this device. Better than I expected

Have been using 640 for almost 2 years. Majority of it with 8.1. After recent upgrade to 10 there were so many problems I just shut phone off and put sim in my old Galaxy SIII. Wow feels like its a new phone next to the Lumia. Been using Windows for years and regretted every update they ever put out. They never test or listen to the public. Not saying the other OS giants are much better but willing to jump ship and go elsewhere.

Tried it twice and had to go to service centre due to software proble... moreI also upgraded to Windows 10 but it messed my phone up, apps misbehaved and it used so much data, I rolled back to 8.1.As much as I love the Windows mobile, Windows 10 bad experience and lack of available apps means I'm now looking at a Nexus android mobile.
If you DON'T want:
Proper facebook app with
Reliable alarm clock
Apps that work
Internet explorer app that keeps the page you were on after minimising the app itself
A reliable phone
Then get this phone!
