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

please post a ROM in Portuguese because that apparatus and hard to find roms 4.2.1. thank you
This ROM have Portugues(Brasil) and Portugues(Portugal)
Hi mastersanta,
Its the best 4.2 ROM for lenovo A820. Its almost perfect. But is it really based on Linux kernel 3.4.5 ? Or you mean S150 ? By the way, Snap camera is as good as the official camera app this phone had.So this is the best 4.2 ROM.
Hello! The new ROM is almost perfect
But… it surprised me this morning, because alarm clock did not powered the phone on and I overslept 
After I powered it on manually it cheerfully displayed the message "Missed alarm". So everyone remember to leave your phones on or use scheduled power on.
I have the same problem – alarm missed when phone is off
Do you use default alarm clock, or some other app? If you have it on SD card that might be the reason.
I can also confirm that alarm fails to activate when phone is off! Have tried both the official and third-party apps. Not on SD card.
Another persistent issue: Random lockups at lenovo boot up screen. Must be a problem with porting base. I guess this will never be solved
My screen went off even when the phone had 37% of battery charge remaining. Got succeeded in turning on only after plugging to power, when the phone rebooted and displayed 37% power. Then of course, I left it to charge further. Seams some bug ? Hope in next release the issue will be resolved…..
Fine Rom. Wifi, Gps, Camera, video, gmail all work fine by now
I can not confirm the problems here described. But android can be complicated. When you let the alarm-clock go into deep sleep, it will not wake you. And if your battery is badly calibrated …..
MASTERSanta, a fine job !!
(If you intend to make a version IV, could it be just an update and no complete rom ? Avoids a lot of work.)
I got freezing on Lenovo logo. In version I and II I didn't noticed it (someone did). It implies I cannot use power on/off schedule in combination with alarms at all. Today I tried wakeup my phone before alarm time but because of freezing I overslept again.
WTF ? Why power down your phone during the night ?
Get MacroDroid and Greenify.
Use (or make yourself) a macro that puts the phone to sleep over night (WiFi off; AirplaneModeOn; all other apps greenified). Let the alarmclock stay awake. Make a macro that wakes up the apps at the desired time and puts the alarm volume on max !
You will consume during the night between 1 and 3 percent of your battery and you will keep your job !
Have fun.
I power down at night because battery keeps hardly a day.
Alarm is an essential function that starts my day. In all roms it worked fine (including MS I and II).
Hope this can be fixed ASAP and no need any macrodroid, greenify, gravity and so on…
The vMS 2 was a deodex ROM but the vMS 3 isn't.Why?
Also I have to add can't turn off Alarm via settings bar.If I'm not wrong that worked fine on vMS 2
