Did you try this? How to back up your BlackBerry KEYone
https://www.crackberry.com/how-back-...ckberry-keyone
to speed things up use the physical keyboard shortcuts these make using the physical keyboard not only a joy but make working the phone much faster. I can be sitting with a S8 user and both go to open say Untapped and why he is scrolling I short press u and I am up and running.
I am not sure what accessories you mean? I have a few cases, bluetooth headset, smartwatch, car connectivity, it's setup to work with my Amazon Echo.
I think we need to remember this device is not going to beat a S8 in speed but for the stats it surprisingly close in real time usage. for the difference in money and the physical keyboard it made sense for me and I am happy with my choice. I have acces to a S8 and I have an IPhone 7 and will always grab this phone. I just am comfortable with it but it's such a personal decision on how you work. check out snapseed if you want better camera software as far as cameras go this is by far the best any BlackBerry has had.
hope that helps some
