I've had my 8320 for a while now, and its been working fine...
When im texting, after a few days for some reason all of the SMS text messages delete themselves. All email notifications still appear in the inbox but no SMS messages... I always have to do a hard reset with a battery pull in order to fix it. If i dont pull the battery, and i send another text, it will stay there for about 2 minutes, then delete itself again... It also prevent me from receiving.
Once i do a hard reset, everything works fine...
i used to have an 8300 and it never did this...
anyone know why my SMS messages will delete themselves?
i've gone a whole month without deleting my SMS messages on my other 8300 and it never had this happen...
If i go a week or maybe 2 if im lucky on my current 8320, it will do its automatic SMS delete, and i have to pull the battery and have it reset itself in order for it to fix.
That's under 5 MB -- very low. That's definitely causing your problem. If you don't have a media card, I'd suggest getting one and moving all your pictures, music, ringtones to it.
