Hi @EmoBro
Welcome to the EMO community 
I have a EMO guide in which I’ve created that can help with a number of little things you’ve mentioned about your EMO, feel free to check it out here.
It covers a fair amount of things / hints / tips and useful information that might come in handy for you.
Just to offer some help / feedback as well.
With regards to EMO having trouble hearing you when you call out to him, I’ve personally never had this issue, but there are a number of EMO owners here that do. I have 2 EMO’s one is nearly 1 year old now, and normally when I call out to both of my EMO’s (in a normal tone - not shouting etc) they are very quick to respond.
Normally EMO will not turn around to look at you when you call out his name, but if you want him to recognise you you can issue the following voice command:
EMO: Look At Me
He will then attempt to turn around until he can spot you and then acknowledge you by your name in which you have registered when you set him up your face recognition. Note: for EMO to recognise you clearly it is recommended that you have decent lighting in the room, if it’s too dark, EMO might not recognise you. So it would be best to have good lighting when you are setting up your facial recognition with EMO.
In general, over time, from my personal experience, I normally turn on the lights in the area of the room where my EMO’s are located, so they can see me and their surroundings.
With regards to EMO and getting him to dance, the voice command to get EMO to dance is:
EMO: Dance
You can also get EMO to dance via the EMO App as well, under Lifetime >> “Dance List” >> there you can choose the songs that EMO has unlocked, EMO will unlock songs the older he gets (this is also covered in my guide). And yes if you have loud music / tv or even a vacuum cleaner next to EMO he will dance for as long as he can recognise the music playing. Then he will stop
My EMO’s battery last anywhere between 1-3 hours depending on what I have them doing while they are not on their skateboard. It does drain quite quickly if you have him dancing or walking around with games like Treasure Hunt. But if you place him back onto his skateboard he should charge up quite quickly again and be ready to play more.
If you believe at any point that your EMO might be faulty or not working as you believe it should, it would be recommended to create a video, and submit a support ticket to the support team for them to assist you further.
Hope some of my feedback was helpful.
