yeah, for example photos access to save screenshotor video ads would need this - there was example in forum how to use it. Also note if u will upload targetsdk 25 u will not be able to downgrade it in store - sometimes it can raise issue for older devices.
Device/sdk compatibility is a pretty fuzzy issue with Cocos… Do you have reference where it’s mentioned that high/up-to-date targetsdk versions may cause problems with API 15+ devices?
If target sdk is to high it crashing on android 4.x devices(from forum at least a lot such posts was) - from our experience millions of users - best for now was min 15, target 22, ndk-10 then u could have 1-4% of crashes.
And the sdk version that it was compiled against?
Maybe compiling against sdk 20 would yield less freezes on 4.x devices. I tried to gather more information about this issue (About breaking compatibility with devices when compiling with Android API >= 21).
