Hi, Bit of a long shot I know, given the multitude of apps and setups that could be causing this, but hopefully someone can help. Sometimes my phone just won't come back up at all. Lock and power buttons do nothing and it needs me to pop the battery to get it back I don't want to push anyone down this line, but I get the feeling it's related to being in the stock case? Any ideas, it's been happening a couple of times a day for the past few days now? It's on II4 just so you know.
