When the battery eventually arrived, I used it for a week. Every text that I received whilst using this item, was repeatedly sent to me; up to a maximum of fifteen times! Also, I lost access to my Android files (curiosity), only had access to my File Manager, which didn't hold all the info that Android stored.
Changed the battery back to my old one and all the above faults have been rectified (for five days at least).
No need to wait and see. New battery marked for recycling!
