Not sure why but there is a HUUUUGE delay when calling pstn numbers using skype, plus the software seems to hog memory. but with sipgate its almost quicker than cellular!?! can hold a conversation quite nicely.
[8525, TyTN, MDA Vario II, JasJam ROM Development] smarty77:
Weird

I have tried to alter the xml file to my own settings... I have Tiscali Voip... but that doesnt work... I made a sipgate.co.uk account.. I alter the xml file again..

Create a cab file...

But on my today screen it says always "internet calling: available"

Does someone have a idea? I read the whole toppic (+/- 20 pages about voip on WM6)

Try to flash stock rom....if it helps.
[One (M7) Q&A, Help & Troubleshooting] rigodon:
Hi,

Phone has the latest stock ROM (Android 4.4.3) and starting a couple of months ago, it start draining battery a lot faster than usual). I already wiped the cache partition, but it didn't help. Can you suggest how to determine if it's a hardware or software problem? Can you suggest some app to detect what's the app draining the battery?

Thanks
[One (M7) Q&A, Help & Troubleshooting] silent_bob52637:
Factory reset then install apps one by one with a gap hour or so between each install then when your battery starts draining again remove the last app you installed should be the culprit

If you cant find the culprit i would say its the fact most batteries wont last a day once they have been cycled incorrectly

Also have you dropped the phone at all or has the battery been bounced off the floor

Check your IDs again. Just to double check did you recompile after modifying framework and again decompile? IDs in public has to be created you cannot leave a random id there sorry I have to be precise to narrow down problems.

While I didn't ever have this problem on CM11S, try going to Settings -> Display -> Turn off Prevent accidental wake up.

[ONE Q&A, Help & Troubleshooting] Heisenberg:
Honestly, asking for a ROM recommendation will get you nowhere because you'll get ten dudes with ten different opinions on which to use. Read a few of ROM threads to see which have the features you like, and read the last few pages of each thread to see if people are reporting bugs or not.

Transmitted via Bacon
[ONE Q&A, Help & Troubleshooting] Cheesus182:
As mentioned above, too many ROMs and everyone prefers their one.

Only thing I really advise you on, don't flash a CM12 ROM. In my opinion its very buggy and has more issues than its worth.

Go with a CM11 ROM for now but if your going to flash anyway give a factory reset a try first.

as i understood from reading a lot ir is possible to downgrade only with previous rom backup, or at least efs from previous backup is needed... can anybody comment is that correct?
[Galaxy S 4 Q&A, Help & Troubleshooting] Lennyz1988:
Guys listen. I see all sorts of "possible solutions" coming around.

It's impossible to downgrade from 4.4.2 to 4.3. It's also impossible to downgrade from 4.3 to 4.2. So it's probably impossible to downgrade from Lollipop to 4.4.2. You guys should have known this before you started flashing.

The only thing that might work is to flash a 4.4.2. custom rom. Other then that, you can't roll back officially.
