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

thanks man good work !
also, if you could fix the battery indicator when charging the phone when it's off (it remains the retro-illuminated screen) could be another welcome addition <fixed>
Small step forward…
Headset button is strange problem:-
Phone off-state, the battery animation.http://lenovo-forums.ru/topic/.....s2z/#entry97618
Very good rom, but it got high battery consumption.
@konstr - Just be careful because it can damage QuickBoot and other things from off/sleep the phone. I already fixed it with another file and for me everything is working properly. But plus for you
@ktatar156 - In the first hours always energy consumption is larger (building databases, multimedia search through the gallery and other stuff). Check background processes and Google stuff, giaur500 wrote about this on page 22.
WIFI ISSUE:
Mastersanta,
I found BUG in the newest version of your ROM.
When I'm connected to the Wifi Hotspot and then i run application which use GPS signal (Google Maps, Facebook), my wifi driver in Lenovo is suddenly stopped working.
Every time when I'm connected to Wifi and i run aplication which use GPS, wifi signal is lost and I can't connect to the hotspot. I have to restart Wifi Module and then connect again to the wifi. But… i can't use those apps on WIFI.
Could you fix this ASAP?
My GPS module is always turn on.
It's not a rule, but… Wifi driver fail very often.
I test the GPS in the YGPS (engineering menu) and I never had that problem. Sometimes I used Google maps with LTE mobile router (Huawei) and also not had problems of this type. I'll check this but I think that this is a single case associated with your router…
