No option for inserting both dual sim alongwith micro SD, very much annoying. Other companies provide this option. Now a days its common to i.sert two sims at same time, why Samsung does not make this provision.
Don't know if people are so trying to get a personally notification sound but here are instructions if so. 1) Download the sound you want in mp3 format. 2) Open Samsung File and go to the download folder where you downloaded the mp3 and copy it and move it to the notification folder on the internal storage (the actual phone, not SD and to find the notification folder where it says essentials press it and switch it to all). 3) after that go back to the notification sound option in the settings and it should appear. Your welcome.
