    I want to update my phone system to the Android Lollipop system. I want to know if it will delete my apps, contacts, pictures, memos, etc. Will it delete the ones on my SD Card and the ones not on my SD card (like my contacts and photos that aren't backed up)?

    Hi, I do not think so. All your data should stay there. It might overwrite some settings, like announcement pop-ups. But based on my experience: I would recommend to check some videos or overviews, to make sure that you know that you want to upgrade. I was not that happy with upgrading to Android 5.
    Hope it helps

    Just by upgrading the phone to new OS will not erase the data, but take backup of important things (just in case).
    Also, you are upgrading from one Android system to another, so I would definitely recommend a Factory Reset from the Recovery menu (not from the Settings of the device) after the upgrade (I do it before upgrading too).
    Many people don't Factory Reset their phone by the above method (Recovery menu) & then their phone lags, becomes slow to the point that they are annoyed with their phone.

    When you say updating are you referring to the OTA (over the air) update that shows automatically in your smartphone or will you have to flash a new one manually? What smartphone do you have?
    If it's automatically it won't delete anything but I strongly recommend that you do a factory reset afterwards. After the factory reset you will lose everything that's in the internal storage so pass the photos and videos to your micro sd card or pc. The contacts will not be lost if they are synced with Google (go to the Gmail website in a pc and go from "emails" to "contacts"and see if they show up. The same applies if your flashing a new Android system manually, everything will be lost in the internal storage. Nothing will change in the micro sd card, don't worry.

    No, but just in case make sure backup all everything in your phone.

    Yeah, always do a backup before, preferably with the PC program from the manufacturer of the Smartphone. Google backup is definitely not enough. Maybe someday we can have a full backup like iOS does.
