I consider myself fairly competent with tech, but I am more of an Apple guy so I had very limited exposure to Android, so far, and my problem is that I want to set up an Android tablet (Acer Iconia 16GB, running Android 4.2.2) for usage by an older person (my mother).
For the time being she will only use Skype to communicate with relatives and friends.
How can I set up this so that it works basically as a single-purpose device? Are there any utilities or apps I should install? (For example I noticed that the font, even at the maximum size, may still give her problems- she will use Skype for voice/video only, so screen space for text is less important than being able to read messages and labels).
I am also worried that notifications (including the ones about patches/updates) may give her anxiety, at least at the start, so I'd like to know if it is possible to disable most of all of them.
If anyone has other suggestions for this use case, even if not explicitly mentioned in my question, please contribute. It's my first attempt at this so I may be missing a lot.
