I cannot believe how many people are having trouble with this ROM simply because they cannot follow directions. I flashed it last Friday and it has been running flawlessly for me. SMS, MMS, Data, voice....they all work. I have not seen anything even close to what I would consider a high amount of data usage. I can't speak to battery usage simply because I was at home most of the weekend and then at work all day yesterday and for the vast majority of that time the phone was on A/C power. Still, this ROM has been a joy to use so far. I think the difference is, I followed directions when I flashed this ROM. I performed a factory reset and also was redundant and did a wipe of the cache and dalvic cache. I also flashed the Slim GAPPS thus ensuring that I was using the recommended GAPPS. I will admit that I hate my calendar displaying in the inverted colors so after I had Titanium Backup running on the phone again I uninstalled the Slim GAPPS calendar and installed the Google calendar from the Play Store. I do understand how people might want to try and cheat the process by not performing a full factory reset and simply try installing this ROM as an upgrade over a different ROM and if you can make it work...more power to you. That is great. But when things do not work, don't flood the forum with your complaints about the ROM. Go back and flash it properly first. I am sure I am going to be pretty unpopular with some people after I post this but enough is enough. I read these forums to try and get a feel for how good a ROM may or may not be. It is very misleading if you do not follow directions and then post complaints here about how things do not work. You are doing the community a disservice when you do that.
