I recently got a Lumia 830, and the phone is great, but I feel it's a bit big and difficult for one-handed use. I'm think of selling that phone and going to a lumia 925 (or downgrading to a 735), which is comparable to the 830 but smaller. However, I'm reading through the thread and I see lots of issues arising, particularly after Cyan. Of course, I'm only hearing about the issues/complaints. Has the Lumia 925 been stable and reliable for most?
