we struggled with this. My person had just got a diagnosis so pretty early in the journey but tech is becoming inaccessible.
Issues - new iPad has no home button. Caused confusion +++ Device hasn’t been used much but old one wouldn’t allow access to iPlayer etc.
At least if you replace both at the same time you can get them to behave in the same way (iPhone SEs have home buttons). Also two charging cables usb-C and lightening if on different device generations.
You can buy second hand from cash converters type places. Phone attrition rate is high so I do that now. My mindset when the iPad replacement happened wasn’t where it is now so we bought new.
I set the new devices up from back ups. This was actually painless. Make sure someone reliable knows device PIN and iCloud password. EPICF struggles with finger print technology so has to constantly put in the password she can’t remember (can I take this off….need to check, it might help).
There is an assistive mode for dementia but it is really basic and confuses the EPICF (Elderly person I care for) and reduces functionality too much eg. Can’t send pictures via email.
My One wish is that it was easy for me to take over the device remotely to sort stuff out. I have no idea how so many apps get “accidentally” deleted and need reinstalled. I used to be able to talk them through it but now they can’t follow instructions/ screen descriptions so I think we are on the Home Screen and am telling them to open the settings app but actually we are still in the middle of a phone call screen. Even flipping into loudspeaker mode so the screen can be looked at while we talk is challenging.
The iPad charger has been missing in the care home for a month and it hasn’t been mentioned once. I only know because visitors told me and the device has remained uncharged and invisible on the network.
