Lenovo A820

Changes/Fixes (not all mine!)
1. Kernel and Modem.img from S150
2. Added: Busybox, Xposed, GravityBox, TotalCommander, FlasPlayer, ads filtering
3. GPS set for Europe
4. Improved feeling when scrolling the list. Looks like it from the ROM Infrared/Cappa72.
5. FM Radio from Lenovo ROM (works without headphones)
6. Superuser/root manage by Koushik Dutta apk ( i think it's looks better )
7. Separate ringtone for each SIM card (in settings: voice-call ringtone = SIM1(3G), video-call ringtone = SIM2
8. Enter to the EngineeringMenu in DevelopOptions
9. Reasonable number of gapps
10. 1% step battery indicator (changed appearance)
11. Changed font, Holo dark theme
12. Silent camera (focus sound), and record to MP4 file
13. Management of programs startup in Settings
14. More options in the Reboot menu
15. Centered Dialpad, little fixed application of Contacts and SMS
16. Replaced mount point of internal memory and SD card
17. Good Polish translation I think…
18. A lot of things I do not remember or have not seen/known

Changes/Fixes:
1. Update Market, and other Google stuff
2. Replace Android Keyboard with Google Keyboard ('swype' will work after automatic update only via WiFi)
3. Replace default Andorid Calendar by Google one
4. GravityBox out of box, Xposed without Installer. If you have problem with it you can manualy download and activate Xposed directly (from XDA)
5. Fix problem with voice recognition
6. Fix problem with search box on desktop
7. Fix email app (look and work)
8. Fix problem with Google Drive and other strange apps
9. Disable launcher rotation

Changes/Fixes:
1. Replace root application. Previous after update crash and not work  
2. Restored old good Calendar app. 
3. BesAudEnh work. However, I suggest switch off because weak sound.
4. Update gapps and other things. 
5. SMS – characters limit after which the message will change automatically to MMS'a changed from 4 to 64. For MMS add subject or other media as always.
6. Added support for init.d scripts + some stolen scripts for test 
7. The choice of destination (Phone/Sdcard) during installation for local *.apk file (not Market, and not full translated to other lang).   
8. You can take panoramic pictures.
9. Odex, Zipalign, graphic optimization, and hundreds of other things that could go wrong
