I have just purchased a Vox for my Mum in the hope she will manage to receive emails and photos from me while I am on holiday.
I have been reading this forum in the hope I will become familiar with the reader before I try to explain it to her. It's been rather scary reading and I wondering if I've made a mistake....
Any tips would be gratefully received, also answers to the following:
1. Wifi - I have connected the Vox to my wifi, Mum lives nextdoor and has no wifi. Will popping into my house everyday or so work or could she lose the wifi set-up?
2. Can I de-clutter the home screen? She struggles with the TV remote as there are so many buttons/options!
3. If I can't de-clutter the home screen can I rearrange it?
4. Has the problem with the Vox not opening Kobo books been fixed? If I buy her Kobo books from the Kobo site will they now open for reading? I don't want to download the apps to make them work.. I've read about that and it would be too complicated for her.
5. Anyone who uses the email function please tell me if it freezes? Will receiving a low res .jpeg from my iPad cause any issues?
6. Do experienced Vox users find anything that especially causes problems.
If you've read to here thank you:-)
