I tried updating my ROM to latest Myn's over the weekend, but had to nandroid restore back to Fresh 3.4. Here are the issues I found:
Titanium Backup does NOT seem to restore all my apps and settings as advertised. This is a problem I've had before. For example, contact links, SMS, folders in Folder Organizer, widgets...lots of little things. To be fair, I was not using the paid version...I've upgraded to the paid version of Titanium and may give it another try. I've also noticed that Folder Organizer has an import/export function, may try that too. But it's such a royal pain to get folders and widgets back to the way I want, it doesn't seem worth the trouble unless there's a huge upside.
More troubling than the above, I noticed that after I updated the ROM I started to get random reboots (I was running netarchy 4.1.9 no HAVS with my Fresh 3.4, not sure if Myn's ROM updates that kernel or not). I have always had problems with stability on my Evo, not willing to give an inch in that category! I'm certainly willing to try different kernels, but again not unless there's an upside, which brings me to...
I didn't see any big upside. Believe me, I wanted to love it, but I really didn't see any significant differences in smoothness or functionality (that is, when it wasn't rebooting). Like many people, I generally test this simply by scrolling around from page to page, or up and down in my apps list...in fact, if anything, Fresh 3.4 was smoother and faster. I get quadrant scores of 1,300+ using Fresh, didn't test with Myns.
So, for now I will probably stay put, unless someone can point out some upside to Myns that I'm not seeing. Is there functionality buried in there that I don't get with Fresh? For example, I saw in one post that Hulu was included in Myns...is that true, and if so does it work well?
