[Honor 7 General] AmitJordy:
I received an OTA for PLK-UL00C675B320, which is Android 6.0 marshmallow and EMUI 4.0. My comments inline in Italics

The changelog as per the update is here -

[New Year Theme]

- New Year Theme added

[Multi Window]

- Supports Multi Window

[SOS Feature]

- SOS feature added (it was there in B170 as well)

- Can send SOS messages (my advice is to turn it off for regular usage, it can send spurious SOS messages)

[Application Compass]

- A compass (that is really slick)

[Alarm Ring Tone duration]

- Can combine different sounds for a really long alarm

[Screen Recording]

- Screen Recording

[Join Contacts Feature]

- Join different contacts (was there in B170 as well)

[Intelligent Contacts]

- Group Contacts by Company name

[Message Cancel within 4 seconds]

- Cancel a message within 4 seconds (basically adds a 4 second delay, works only with the default Messaging app)

[Soft lock]

- Adds a button for screen lock along with Back, Home and Task Manager

[Some Known Issues] - The update says so, but these are not issues per se

- Applications like Native browser, magnifier, UC browser and Screen lock App removed

- Voice search removed (no more Dear Honor or Hello Emy)

- Honor ROM icon changed to Honor Club

- AM / PM will not be shown in Clock on the Lock Screen (Biggest issue of this update, especially for travelers)

- Battery setting removed from Settings (but the % remaining display can be enabled from "notification panel and Status bar" settings)

[Pre-upgrade considerations]

- 1.13 GB large

- Charge should be more than 50 %

- During downloading the upgrage package, phone remains functional (so enjoy those missing apps one last time)

- This version can roll back. Please refer Rollback guidelines available with the release. Roll back will clear User Data, so backup is recommended (I did not find any roll back guidelines anywhere)

MY OBSERVATIONS ON CHANGES

- Been using it for 6 hours now

- Biggest issue seems to be that the option for FAST CHARGING is no longer to be found. The phone does seem to fast charge though, so no option to turn off Fast charging

- Settings are organized now in groups

- Still no Screen Pinning

- Scheduled Shutdown and Start option present

- A few apps like Virtua tennis still don't dance along

- RAM usage has increased. From having about 1.8 GB free in Idle state with no apps running, I now have 1.2 GB.

- Right after Cold start, On lollipop, I used to have 2 GB RAM free, now I have 1.5 GB RAM free.

- So 500 MB to 600 MB RAM is used more here.

- Contacts now open in full screen, rather than a smaller window as in Lollipop

- Pro Camera is now called Professional

- All Other features the same

- Good Food mode is now moved to Settings and Time Lapse takes its place on the main screen

- Everything else in the Camera app seems to remain the same

- Some new cool wallpapers (there is a shark one)

- Icons now have a rounded rectangular box around them and are transparent In lollipop they were filled with a random color)

- Some App icons still have random color fill (like whatsapp) but some like Air Droid just have a transparent rectangle. Some, like Uber, still have the corner of their icons truncated

- I think it freed about 300 MB from Internal Storage (I am not sure)
