We used to download Themes in apk form directly from short links given by the developer through youtube. Afterwards these apk themes were installed using “custom one UI theme installer hexed” app. After installation the installed themes were shown in the galaxy themes apps. From there we used to apply them and then apply high contrast blue theme and then restart the phone. After restarting the phone , the new theme used to get applied successfully. This was happening properly till 23rd may 21 update. After the update the themes were getting installed byt when we APPLY them the -1/T500015 error code appears. So something has changed after the update and we are not able to check this anywhere. Even on google if i type the error code nothing shows up. Please if any one in this forum can help with this please let me know.
