Avast kept crash looping, and twitter would crash any time I tried to open it. I then tried to open facebook and got a error message from that. The UI was stable the whole time though. I went into powermenu and selected reboot, and now my phone is stuck on the Galaxy SIII logo.
I went into recovery and cleared the cache, but when I tried to clear the dalvik I noticed it wouldn't mount /data and it showed internal storage as having no space left, I thought it might be an issue with that version of TWRP, so I updated to the latest one and I'm getting the same thing.
Could this be a hardware issue? The only internal storage I have access to is the system partition.
Any help would be appreciated.
