LINE Customer Insights

1. Put the sound option back to make everyone's life easier please.I use this app everyday and for long periods of time on call, especially on quarantine, and until this latest update, the sound quality was decent and I could properly hear the other person.

2. Essentially, the app and service just doesn't work at every turn.Been using LINE for almost 4 years and my only qualms are the account transfers (it deletes everything) and for some reason, I am now unable to send photos.

3. Then there are times it says "Unable to send." I checked to see if it was my phone, service provider, apps that could be causing a conflict and etc.... my friend who has a higher Samsung model isn't having any problems.

4. I can set sonds on all my other messaging apps and the funny thing is that the line app sounds are in the lists on both phones.

5. Just has a few annoyances when it doesn't want to connect the call or gives an error.Doesn't work well, server issues.

6. Unfortunately, they have decided that swiping left on the message was the best way which is opposite of every other messaging app that allows swiping to reply.

7. You have market power now but don't depend on that when you have such an annoying feature compared to other apps!I use line daily for a game I play.

8. Much better recently probably the only call app that hangs into the call for dear life and doesn't drop when switching from wifi to 4g.

9. Sometimes they come in and at other times I get nothing until I open the app or send the person a message myself.

10. The swiping out doesn't work very well, especially when the message is only a few characters.

11. That then stopped, but then wouldn't recognize other people's QR codes, saying there was a server issue.
