Having a similar problem with an XPeria M4 Aqua, I've Googled it and had no luck finding a solution. I hadn't unmounted my SD card when the apps disappeared. I tried to clear the data for XPeria Home and I restarted the phone a number of times, neither of which helped. Problem is, I can't reinstall the apps now because of a lack of storage space. I had deilberately stopped updating them to save space but I can't download an older version now and don't have enough space for the latest versions. One thread suggested I unmount then re-mount the SD card which I tried and have probablly lost the apps for good.
In the unlikely event that they can be recovered, any tips would be appreciated.
