My HTC Incredible is always telling me I am low on memory. I will delete up to 20 MB, but it will still say I'm low on memory. I cannot send or receive picture messages, (I do not know if this has to do with the memory or not). It says I have 151MB free in my SD card, 6.14GB free in my internal memory, and 433MB free in my phone memory. What's up with this? It's not rooted, and I don't want to root it. Thanks!
