[Q] Problems with freezing and phone soft-resetting itself topic

Hey guys, I've been having this issue for a while now, but I've been deathly busy the last couple months so I haven't posted about it! :eek:

My issue is this: I've been having issues with the phone randomly freezing which results in the phone soft-resetting itself. I also have issues with apps randomly crashing. Occasionally, I will turn off the screen and when I try to turn it back on, it won't work and the phone will soft-reset. Another interesting thing I've noticed is that when I'm listening to music (stored on the SD card), sometimes I'll get distorted sound for a while. Usually, it fixes itself, but occasionally this leads to the phone soft-resetting. In general, since these symptoms started showing up, I've been dealing with stuttering and lag on my phone :(

Is there a possibility that my microSD card went bad? (could that even cause this kind of problem?) My card is kind of old, but I don't have any spare microSD cards to test

I'm currently using STS Rom on MK4, but this problem happened before I flashed that ROM. Before that, I was using Whompasaurus 4.2 (MA7)

Please let me know if you need me to do something to my phone!

Thanks in advance! I appreciate it :)
