Re: A few questions regarding Android
Lots of options. Google+ has native services that will do this, but Box and Dropbox also do this. I personally prefer using 3rd party services...I am a huge fan of Google but I dislike Google+ a lot.
PhotoStream, automatically uploads photos you’ve taken and easily access them on a computer.
Google has a native service that does this now.
Find my iPhone. To locate lost phones and remote wiping
Will track it, lock it, wipe it, or ring it. Note that you DO have to set this up in advance though. So I'd do this right after buying your phone.
If you mean a system backup, Android has a built in service that will automatically restore your apps after a factory reset. There is probably a way to auto-save your other data as well, but I have always done this manually. I am in the habit of saving stuff to my box.com account by reflex.
Cloud backup. This gives me a peace of mind knowing that I can restore everything if I do lose my phone
Many google apps are now cloud based, so there is no need for a backup. Google music, Google Keep, and Google Maps are examples. I have my own MP3 library that I keep on Box.com.
The malware issue on Android has been greatly exaggerated, even by some Android users. I have had Android phones since 2009 and have never gotten a virus. Don't know anyone else who has either. I never run anti-virus.
Do I have to install Antivirus on Android?
The chances of getting a virus without disabling security on your phone is less than 1/10th of 1%. - Android Accounted for 97% of All Mobile Malware in 2013 - Even if you completely disabled security and started sideloading stuff randomly, the chances are still less than 5% in the US. Security is on by default and you have to manually disable it in "settings" in order to install anything that is not on the official google market.
Don't know if you can record directly to SD, but you can always move it to SD right after. Android allows you to access files directly just like on a PC or Mac. You just need to install a file manager, and there are many good ones that are free.
Can I record videos/take pictures and directly store on the SD card?
Not without rooting. Nowadays this is not really necessary anymore...even dirt cheap phones have lots of internal memory for apps.
Can we install apps on the SD card?
