I have a stock LG LM-X410ASR (Xpressions Plus) that came with Android 8.1.0 installed. I installed a 32 GB SD card and installed a bunch of apps. On this phone, if you go to Settings/General/Apps & notifications/App info, you can tap on an app tap on "Storage," and then "Change" storage from internal to SD, if the app allows it. I did this for every app that would allow it, except for some that run better from internal storage, or whose widgets won't work right unless they remain on internal storage.
I've had this phone since the weekend after Thanksgiving, having bought it on sale at Wal-Mart. Since then, it's been performing well, until today.
I have Nova Launcher installed, as well.
I was updating apps in Google Play, and Castbox didn't want to cooperate, so I cleared Play Store cache and rebooted the phone. When I rebooted, I saw a lot of grayed-out shortcut icons on my home screens. DriveSync also had a failed sync. When I went to DriveSync, it wanted me to find the root of the SD card, again, so it could have permission to write to the SD card. When I tried to enable this access, I could see the SD card, but the hex name was not visible and DriveSync did not accept my selection.
Neither Astro File Manager nor the native file manager app would allow me to copy, move, delete, or create files on the SD card any longer.
I have rebooted the phone multiple times, and have been paring down my apps in preparation to do a factory reset, hoping this will solve my problems. Each time I've rebooted the phone, a different selection of apps was grayed out or missing.
At this point, I'm not sure whether I have an SD card problem or a hardware problem with the phone. I would like to find out so that I can replace the SD card or file a warranty claim with LG.
Would a factory reset followed by installation of apps that can be "changed" to SD storage, changing the storage location, and rebooting the phone be sufficient, or should I try this with a brand new SD card installed?
