    Hello
    I've just got a used S5 SM-G900F Baseband Version G900FXXU1ANC7 and I have noticed that there is a large amount of delay when calling !
    the G900F is the European version, it doesn't connect to LTE but that doesn't matter to me.
    My carrier is Ultra Mobile, its a mvno that uses T-mobile network
    here is the delay shown in this clip :

    I have tried my SIM in another phone and there is no delay
    any ideas ?
    -----------------------------------------
    edit :
    thank you so much ironass , after the manual update there is no delay in the call audio

    My first suggestion would be to update your firmware from the very old Android 4.4.2 to the latest, Android 6.0.1, for your model of phone, CSC and Product codes, as per #1.11 of 42 Galaxy S5 models - Dummies Guide to see if that helps.

    thank you so much for the great article.
    so now I want to manually update my S5, but I couldn't find the exact same version "G900FXXU1ANC7" neither here : Firmware for Samsung sm-g900f - SamMobile nor here : https://samsung-firmware.org/model/SM-G900F/page/9

    how can I know which other version is compatible ? and will the update wipe all my data ?
    thank you again @ironass

    Your need to re-read #1.8 of the guide again. Look for your Product Code if there is more than 1 version.

    See the warning in #1.11 of the Dummies Guide but it will not, "break", your phone as such.
