I've got a very odd problem with my Desire. Whenever my phone receives a message, or when I send one, it hangs for a period of time. During this time I can get out of the messages app, and I've noticed it gives me a 'low memory' notification (I have 25MB free, so it should be fine). It gets to the stage where it gives me a second notification telling me there's not enough memory even to save the SMS. Then it usually suddenly rights itself, and writes the SMS to the memory and that's that - but this is frustrating as it takes several minutes, or sometimes doesn't and I have to reboot. What I have noticed is, when going into the menu and looking at how much free space there is, it's decreasing dramatically. For example, I look at it and it's 22MB. I come out of the menu, and go straight back in, and it's down to 20MB. It keeps decreasing all the way down (I can keep looking at it) to 44KB, which is when it gives me the second warning above. Then it suddenly bounces back to 25MB. Does anyone have any ideas what on earth is going on, and how I stop it? It's meaning that effectively my phone is useless for sending or receiving SMSs. Phone calls, using internet, tweeting, Facebook, all that's absolutely fine. I'm wondering if it's having some issues writing to the internal memory of the phone. Thanks in advance for any tips or thoughts.
