More of experiments:
(from CWM recovery)
-Wipe data/factory reset
Run aroma, for marvel v9 and installed FULL MARVEL
Connected to my home wifi, went to my office.
Connected to my office wifi and changed settings to "NEVER" on settings to turn wifi-off.
Checked my cellphone, it was connected on my office wifi, and left back home.
When i got home i left my phone near my router. WITHOUT unlocking it, for 2hours.
After 2 hours, unlocked it and it wasnt connected! I navigated on menus, etc... for 10 minutes (boring, no apps, no sms, no contacts, INTACT marvel full v9)...still wasnt connecting automatically, so when i got to wifi settings just going into the meny, it refreshed the list and connected to my home wifi alone...!!!
Well i dont know what the hell is going on but that's some serious disadvantage for me. I dont really care for eye candy effects and super duper speed, besides it's only a mid-range smartphone, but this way it's so annoying.
This is my honest feedback. I'm waiting for any ideas tantrums about what to do exactly.
