on one hand, if u r used to kodi16 and build is good, best to stick to 16.1 until ready with backup or restore to change over.

on the other hand, if u r new to kodi and there isn't much in yr build, may be better to remove 16.1 and install 17.1, rebuild it from fresh.

to do that, i assume u know the basics of android apps handling - how to uninstall an app complete, how to get new from playstore or install apk downloaded from pc.

u can always get back to the seller and ask for help n guidance.

but in the long run, u need to get hands on to keep the box in tip top shape to get the max out of it.

the box u bought is among the best available in the market now.

u need to learn at least the basics of how apps work, where to get apps, how to install/uninstall.

best to start reading is u have not been doing so!

there are 3 threads in this section for u to read and ask for assistance:

androidbox thread.. general android devices issues, please read at least the first few pages.

Using Q5 Pro here. Upgraded to Kodi 17.3 recently. Still working fine for me, including Exodus.

Suggest to uninstall Exodus and then reinstall it.

Other apps working fine?

kodi17.3 works well on yr box box.

there hv been issues reported with exodus on kodi17.

but fret not.

get genesis reborn, even better.

kodi details, best to read/ask here:
