I experienced my first hard-lock and then reboot today. It was caused when I search for a name on the home swipe-to-search feature. I've checked again and it seems to do for any search time. It locks up the entire phone with not even the home button working.
Is this a known issue with the Mate 20 Lite's weak CPU or an EMUI issue?
I've left the vast majority of settings on default.
Build: SNE-LX1 22.214.171.124 (C432) This build has created a lot of instability for me, but the Huawei support person told me that there is a new build to fix the issues it causes and I'll have to wait. This is a pretty bad experience so far.
