Been running SanDisk SD cards in my home security cams, dashcam etc for over a year now. No problems. The security cams record 24/7. You should upgrade your cell phonesI have a cheapie micro sd in my Pi (NOT a Sandisk - Adata or Kingston or something) and haven't had any issues - used to run a dedicated Kodi box; now Raspbian with Retropie. Never had sd card issues over years of combined use.
Now, using a name brand Sandisk in my phones on the other hand... Well, as I said above - 2 failures in 2 phones.
