Nope completely disagree, fx I’ve used for years & it’s far far superior than another explorer I’ve used from most manufacturers & play store, it’s strides ahead.
Manufacturers file explorers are very basic & tbh less of the many bloat tracking ware the better imho.
Give it a try, it’s free & you can opt to pay for pro but the free version is very good, connects to cloud drives easily, lots of info, works very well.
As for there job to do, no there job is to release a fully functional handset & they’ve failed to do that.
Camera issues, touch issues, NFC issues, audio issues, the list is growing.
