iPhone XS lower speaker does not work after battery replacement
Hello guys, Two days ago I’ve replaced the battery of an iPhone XS. Everything works fine except that the lower speaker is not working anymore. I’ve tried to unplug and re-plug the speaker connector just like the picture below: [image|2380881] But the problem is not solved yet. Can you show me some possible causes and solutions to this problem?
