Why won't my screen rotate to the horizontal display?I went into settings and made sure that the auto-rotate screen option was on but the display still won't rotate.
Resposta para "Why is my bottom speaker muffled?"If you dropped your phone and the bottom speaker no longer works, then chances are that you damaged it. Before considering a replacement however, you should check for debris in the speaker in case that might be the problem. You can view the troubleshooting guide for more information, HTC One (M8) Troubleshooting. If that isn't the problem then I would recommend taking apart the phone to see if the bottom speaker has been damaged.
