I've been testing Eclipse X (the 4.2.2 based version - he just updated to 4.3 base) for about a week now. I'm getting semi-frequent hangs when opening/closing apps, turning screen on/off, or if something is going on in the background, etc. I also have had about 2 or 3 random reboots (one or two were preceded by a hang).
I've tried wiping the cache and dalvik cache, and fixing app permissions, but that didn't improve anything. When I created the ROM slot, I selected the '2 GB' option, so I don't think it's a low space issue. I did restore data with Titanium Backup for a few of my apps, but they weren't ones that are running frequently, so I highly doubt it's that. Incidentally, I think I'm actually getting worse battery life on Eclipse, too.
I really hate hangs, lag, random reboots and important stuff not working (wifi, mms, sms, gps, bluetooth, video camera, etc). The built-in features are nice, but I'd much rather have a phone that doesn't hang, crash or have important features broken. Are there any ROMs (4.2.2 or 4.3) that will give me the experience I want?
The only reason I really want to get off of stock is to solve bluetooth music streaming (know problem w/ 4.1.2 and toyotas) and Instagram problems (incidentally, Instagram also fights with CM - it crashes when you try to take a video with the front camera).
