Error while charging and generate "spam" in /data/core
Mountpoint and description for memory (sdcard and internal memory)
Occasional problem when performing file operations.
Reduce bitrate for video. The quality will be the same (i guess), but the output file will be much smaller.
Autostart option in settings
Google Play, Google Keyboard
Clock app,Cyanogen Calculator
A ton of changes which even I do not understand 
I checked WiFi Direct – works correctly but need an external application to transfer data.
If you have a problem with the contacts you need to check the options of displaying, or import them again.
Contacts are recognized after a minimum of 9 digits. I can change it but for now I prefer to leave as is.
All tested using TWRP. CWM – unknown, but it should work

1. Added support for several languages. There is no possibility that all is well, but I tried to add as many as I can. I'm not omniscient.
2. Added SIM Toolkit and NoteBook. Removed redundant widgets and some unnecessary files.
3. Adding support for multiple users
4. Fixed a problem with the recording after adding effects.
5. Added support for headset button.
6. Changed the YouTube application. Reason: poor quality of playback in previous version.
7. The little fix in installation script. Added full of BusyBox options witch update.
8. Fixed caller_ID and SMS, little optimization in apk files, ODEX and other things.
Known issues:
1. Occasional freezing on "Lenovo" screen on (re)start. Not everyone even notice  Simply remove the battery and reboot. Probably the reason is Xposed/Gravitybox but thing to check.
2. Miracast still not working

Member Info
I can confirm spam in /data/core too. First I tried to cope with this by using the init.d, but it was poor
Now I noticed that it was a problem with the charging and debugger (any mismatch between the numbers of modules, do not know). Fixed, but still will test it (in next ver.).
@winiu89 – S650 is a cool piece of hardware, but I do not have it
So much to do and so little time
I see a lot of reading. Someone can tell me briefly point out what you have discovered so far?
@mastersanta, any ETA on the new version?
The spontaneous freezing at lenovo logo is not a problem because of xposed/gravity.I don't use that and deleted then I've noticed a couple of times after reboot my phone just freezed at white lenovo logo.
Sometimes in earphones before I start track I hear "click".
In seetings-battery the progress of using wi-fi, games or just of turning on display shows very poorly most of the time I see there cell standby/phone idle each eat 50%.As I remember on lenovo stock there's displayed every little thing you have ran.
Anyway that's buggy less ROM on 4.2 i've seen.Btw why not 4.2.2?Most of the chinese devices now came with this android version.Ver 4.2.1 and below just forget nowadays.Surething that's better than old 4.1.2.Just asking…
Mastersanta,
I use the A820 with this rom as my daily device (I do no gaming, no watching movies, no music) I am really content.
For me the only problem is that incoming calls do not show name and picture of the caller, only the number. That may be a result of not installing the full version II but using the update that our friend Giaur.
BTW. Would it be doable for you to create an update instead of or besides a full version ? I guess that a lot of other people have customized heavily, like me.
And thanxs again for your work !
Your
Wolfgang
At the begining huge thx for your work! I've skipped from holodark and using it for few weeks and only problemem that I've found is cooperation with polish free internet provider (aero2) sometimes after turning on data transmission it takes up to 5min to establish the connection (instead of the fact that both nets indicators for gsm and gprs are full) and even when established it could be from time to time lost out of nowhere?! Enyone has similar problem?
Replacing Aero2 with Play shows no any delay in establishing data connection so it is rather Aero2 network problem.
About "click" before start any track.It does exist with loud speaker too.
I didn't touch any settings in engeneer menu.The click is also spontaneous.
After I did photo by stock camera in the information of photo I've found device model A820T.
My message just for the master santa.I'm not saying that's all a big deal but if he mind fix something here it is.
Hello, why in vMS-4.2.1 II why phone memory and sd card swapped
Anyone have working radio without headspeakers?
I hear only wierd sounds..
Radio without headspeakers is working well in vMS-4.2.1 II. I didn't try vMS-4.2.1 III but I'm sure it's working as well.
Thanks for the rom. The best 4.2 I’ve installed.
