Hello everyone! I apologize if this isn't the best spot for this. I recently replaced the screen on my sister's 4S and now it is acting funny. A little background on me, I've been an avid computer builder for years and have dealt with many Android phones inside and out, so pulling apart a few screws on an iPhone was probably one of the easier things I've done. I'm very thorough and am positive I installed everything correctly. Anyways, some of the issues seem to be software related so we reset the phone to no success. Issues include: no music plays from the music app, although the speaker does in fact work when the phone rings or is in speaker mode, weird right? When the music app is up, it doesn't even have a volume slider anymore (see screenshot). It shows the song is playing but there is no audio. Also, when you go to turn the volume up, it doesn't show the volume bars anymore (see other screenshot). Other than that, it appears to mostly be working well. Any suggestions?
