I am in the fast ring program. After the latest update it was all fine but after using it for nearly 2 weeks the apps started crashing. Its like using a counter. After this much time it will crash. I observed this mainly in the w8.1 app. Also windows central app is not launchin only. The photos app is too pretty bad. Actually now i am starting to hate windows mobile. Android seems much better now. But i still want to use my 640. If any fixes please do reply.
