Ok, I installed SDMerge and I made some tests along the week...
By the way, SDMerge is amazing! :)
But I faced some freezes again... And I realized (after a small observing time) that it starts to freeze after I use the messaging app(sms). Specifically when I don't receive a delivery report (??). After that, it starts to freeze a lot, and in different situations (when a stopwatch app is running, when my phone isn't awake, when I'm typing a message...). When it was in this "freezing period", the time between freezes reduces a lot while the phone is charging.
It only stops those freezes after a couple of days insisting, or a factory reset.
Does it makes sense? Any tips on what should I do?
Sometimes my phone freezes and this is annoying me... How can I find out the reason for this freezing behavior?
It mostly freezes when i'm in the message app (sms), but sometimes it freezes when it are in stand by and my phone doesn't wake up.
I installed cm-9-20130428-NIGHTLY-e400.zip, and I made a factory reset and wiped dalvik cache...
It start to freezes after I install some apps (swype, dropbox, gmail, whatsapp...) and put then in the sd card (in other words, when I begin to really use my phone)
