1.im only using the default one, i only have the free app. not the paid version.
You can set the default for Siyah by going into Recovery > kernel specific options... if you do not have the ExTweaks Plus. Use the, "Remove all files in init'd folder", under those options
prior to doing this.
2. im using uhlps neatrom lite by sale.
I've not installed that ROM, for reasons I give
here, but I don't see it being a problem.
3. i did check settings-applications-running and i stop some of them.
Depending on what and how you stopped them, whatever they are, they will just start back up again and drain your battery. If they are app's or features that you do not use at all then you would be better off freezing them with Titanium Backup, as described in this handy, helpful, step-by-step, dummies guide for getting rid of bloatware,
here. Please read it
carefully!
4. im using siyah kernel 3.3.2
Good! That too should not be a problem as it comes bundled with the NEAT, UHLPS, ROM.
All else fails, try un-installing ExTweaks and reboot your phone and re-install ExTweaks again and
carefully re-do your settings and Save them.
