I bought a new device (ZTE Axon 7) and first thing I installed was Solid Explorer 2.0 as my most used apps. I was able to quickly restore all of my settings including cloud drives etc. I noticed that the performance of this app is quite sluggish on this device. The animations struggle to keep up and the operations (like copy/move/cut) takes a few moment to initialize. Even deleting an empty folder takes a while to delete which is frustrating. I tried tapping back and forth on a folder and the back key rapidly and I can see the animation struggle a lot. I can't tell if this is device specific but it's really bothering me. I love Solid Explorer. I tried a few things to fix it but nothing helped:
1. Disabled all power profiles for SE
2. Cleared cache/uninstalled app
3. Ignored my restore settings and tried as a new setup.

This is a brand new device running Android 7.0 and I didn't root or use Greenify or anything. I will try to record the symptom and attach it here to give a better idea of the problem. In the mean time anyone else facing the same issue if you have a ZTE Axon 7 maybe?

Thank you.
