Two questions on editing. Name and Flats
Hi all. Long time user, veeery infrequent editor here.
I have two questions in regards to editing the building where my dad lives.
The fist is name. It already has a name, but it doesn't correspond to the name printed on the building, used by the residents of the building, or stated in legal buy/sale documents.
My question is, do I need to find digital copies of the building's cadastral record to support the change? or should I just change it?
The second is, I'm adding the number of floors, and units (building:flats).... yet the building has 3 commercial units apart from all the residential ones... should I count those for building:flats? or should I segregate the commercial units in a different field?
And if so, should I include existing but unoccupied commercial units?
USB port compatibility
Hello everybody.
I have a SM-N970F/DS, and my battery life is horrible already, so I'm getting the kit from ifixit which would be easy to use because the other day my phone overheated enough that the back lid unglued itself (I'll ask about it in another post).
And I'm having troubles with the USB port with a few cables. It could be the cables themselves which I tend to change from time to time to get fresh well working ones.
But ifixit only has the little board for SM-N970F, not DS, and I wonder if it would be compatible with my device, as I know these boards sometimes include antennas for some of the wireless protocols.
