[AT&T Samsung Galaxy S II Skyrocket SGH-I727] unibombz:
All I have seen for issues, and it is SUPER RARE, is 'SYSTEM UI stopped working" error, which is probably just a minor framework issue... it is hit and miss... mind you when you get the error, it takes about 30 seconds for the phone to return back to normal working state.

Another SUPER RARE issue, is desktop freezing... but like i said I hardly ever see that happen... Task manager can be your friend, use it from time to time.... Sometimes give your phone a nice shutdown from time to time as well.... or if things get really funky, clear the davlik cache, and allow the phone to rebuild it... sometimes that can even fix issues in my personal experience.

I have to say I am loving Embryo... I have said this before. It is a shame some people still have some issues with things. Perhaps it is an error with wiping the phone, or restoring certain things (bad app data) that is the cause of these issues. My suggestion, to those that want to spend the time, that are having issues, is do a fresh install, from the ground up... build it like you don't have a TiBu backup of your apps, etc.... install apps fresh from scratch (you can easily install play store apps from your PC (play store website) to your phone) that makes it less tedious then searching the app from the phone on the market....see if results change.

As well, find the radio that works best with YOUR phone (make / model / chipset) I am currently using the ROGERS radio, as I am using a rogers phone. I did however try some of the newer AT&T radios for my phone, but found the one made for my phone chipset worked best for my phone, so I just stuck with it

Phone calls work clear and great... Battery life from "out of the box" is excellent, though I am researching more to try to see if I can improve it. BLN worked from default for me, then again I use BLN Pro, as I support it, and love it. ROM customizer I haven't toyed around with too too much, just some basic features and I love it. It is excellent and I can see its potential and its future potential as developments are made.

WiFi I have had no issues with thus far... sometimes after a flash (once the phone has sit for a good 20-30 minutes) I can't say it will matter, but shutdown your phone, pull the battery for good 10min, and reboot (that is a old BB solution) to be even saying that sickens me lol, but suggestions can't hurt.

You should have no issues from a fresh flash of this ROM. Follow the OP.... allow the phone to settle for 15-20 like the OP suggests, it is there for a reason it says that, try not to rush things. If you are flashing radios (mdm.bin) allow that as well to 'bind' to the phone, don't expect instant results. Stay patient, this ROM is really working well. I was a fan of CM for a bit there, but as mohan (and team) has built this TW based ROM, I don't think I need to go back. I can't really find flaws with it yet. It is a SOLID and STABLE working ROM, and I know personally I can always depend on embryo! As time goes on the kinks will be worked out, this is the nature of flashing custom ROMS, not everything is going to be PERFECT... nature of the game everyone. Choose to flash something, don't expect everything to be perfect

Keep up the good work! My favorite piece of eye candy is the good old honeycomb battery mod, It is my personal favorite.

Sorry for my rambling, I hope it is taken as something positive because it was not meant to be anything negative... Now back to researching some scripts to see if I can boost my battery life even more!

All the best everyone, and keep posting, this community effort of issues and problems only makes this ROM better :)
