hi, sure many of you know the X-U has (or for some of us certainly has) a problem with "call lag". this is in two parts:

1) cannot answer calls quickly because sometimes cannot reach the slider, i think if phone was in deep sleep when call comes in?
2) after answering a call, you cannot hear the other person for some period of time after answering, around 5-10 seconds approx.

i have a warranty replacment XperiaU and i'm trying to decide between the newest official based roms (b.1.100? debloated etc., which i'm hoping Sony has fixed some of this (?)) and the newer, apparently fairly bug free CM10 builds here. obviously the latter means unlocking BL which i'm willing to do IF it offers any benefit (to this issue, not really bothered about other benefits, mainly trying to use it as a phone!)

not sure if this is a resource management issue as the first reports for e.g.
say that it had no lag, but later reports clearly say it does.
the video i saw on that thread made the phone look noticely faster than i'm used to on b.1.54

if there's some app or tweak to improve this that would be equally good.

any thoughts/advice much appreciated.

just a note this problem still present in CM11 beta builds i'm using (from

changd to SmartAssv2 governor, usually about 70MB RAM showing free. not using any RAM management app other than greenify. phone actually runs pretty well otherwise on kitkat.

going to try ExDialer (not free? :/) and that RAM manager that i keep seeing recommended.

see some recommendations for this also, not sure specifically what in there is helping?
Some say to delete call logs, anyone found that helps? anyone tried different governors etc.?

or a tweek to keep dialler in memory, like the launcher?

quick update, haven't solved this it's still a major problem with this phone, but i realised you can use the power button to wake it and then answer the call! sort of a workaround, but inelegant.
