Ok, for ringers try using this uploader, seems to work
http://144.230.114.37/adp6/upload/upload.phpThe m.y.x.e.r. ( just remove the dots ) website lets you save ringers to your computer, just use this uploader to get them on your phone...hope this is what your looking to do.
Auto correct turning off....known and reported issue. Hopefully it will be corrected with our maintenance release.
Far as the battery goes, I would give it a half dozen charges to see if it doesn't improve for you. I notice mine drops to 50% within the first couple hours of moderate usage, then drops to 20% shortly after....but remains on 20% for quite a while longer than it actually took to get there...again, known issue, reported and hopefully it'll be fixed with the next update
When that's supposed to happen is anyone's guess, it should have happened in Jan. but I guess they need more time....
We gave em a pretty good list to figure out for us
