Assuming the Samsung charger is a micro USB, yes you can use the Samsung charger for the HTC One.
Yes, it will support 4Gb Micro SDHC, just be aware of the following:Taken from LG-vu.comWith any microSD card smaller than 4Gb, you can set the camera's primary storage by initializing the camera, selecting the "Settings" cog/gear icon in the lower-right hand corner > Primary Storage > Memory Card > Save.With the 4Gb microSDHC cards, the camera will only accept the card as primary storage if you have 2Gb of data already on the card, otherwise it defaults to "Handset" storage mode. You must add music, videos, photos, files, etc. until your 4Gb microSDHC is at least half-full. You may then set the Primary Storage mode for the camera to "Memory Card."
yes i use a 4gb one in mine works fine!
Use a card reader, read the memory card from your computer and reformat it from there.
I'd recommend using a cloth similar to what you use to clean eye glasses, and/or micro fiber cloth for the casing on the phone. There's screen cleaners out there (for computers, smart phone screens, and HDTV's) that you can use.
Yes. You can use a keyboard with a Samsung galaxy 3.
