I Have the same phone but don't recognize these issues. I've seen something similar to the blank page thing but it sorts itself out without restarting the app.
I notice you specifically mention LinkedIn. I don't use that site but I did read their recent web development blog post when they admitted that they had a CSS download of 3.5MB that was causing issues for mobile users. Apparently they've fixed that now, would be interesting to see if that was a cause.
