Chosen Solution
Hello I have an S5 (G900F) and if someone calls me I can not answer. May be the motherboard? Thank you.
Alex, From the forums I have read the only solution, other then replacing phone was to try changing settings. Turn on “Single tap mode” in Accessibility so calls could be answered. You could also stop in and ask the carrier for any known fix. Update, the link below claims to have the fix for your phone. http://www.naldotech.com/how-to-fix-sams…
