[Q] Share media offline in the car - Android Q&A, Help & Troubleshooting

Here is the use case I am trying to solve for: use my former android phone (no data plan) as a media server in my car so my kids can connect there tablets to it and stream movies off of the phones SD card.
I have found several apps that turn your phone into a WiFi hot spot if you have a data connection. The target phone is a droid bionic and is not "activated". I basically use it like an iPod touch.
I have found sever apps that turn your phone into a media server but they need to be on the same WiFi network as the clients.
Is there any app that turns your phone into a WiFi hotspot / router / hub just to share media (I am not looking to share the data connection as there is none on the phone I want to use)?

[Q] Use 4g connection to stream while connected to WiFi

Hey guys.
So here is the problem. I am currently without an internet connection and would like to stream media from a off site Plex Media Server.
Now I could just stream it to my phone (the 4g down is outstanding here, 20mb+), but I would like to watch it on the TV.
I can send a video stream directly to the TV from my phone (using Bubble uPnP), but I need to be on the same WiFi network. Obviously the catch to this is I lose the 4g connection if I do this.
Is there any way I can connect to a WiFi network and keep the 4g connection? This seems like something that shouldn't be that hard, but I'm no expert.
I know I can just use a HDMI adapter to do this, but that renders my phone useless as it has a cable fixed to the bottom.
Thanks in advance!

[Q] Use Mobile Network for data and internet when connected to WiFi

I'm a user of SMB server in my PC and have large music collection in it and use it to stream music on my phone through WiFi. But Since my WiFi's Internet speed is too Slow I prefer to use my 3g mobile network for internet browsing and WiFi only for streaming music simultaneously.. But whenever I turn on WiFi , the phone always uses Internet from it. Are there any ways possible to use mobile network for browsing when keeping the WiFi too On?

Force data connection via LTE rather than connected wifi (g850a so no root for me)

I'm curious about being able to force my phone to use it's LTE data connection rather than a wifi network that it's connected to.
Here's why:
In my car, I have a head unit with a chromecast input through the hdmi port in the back. I put the chromecast there specifically to cast my phone's screen onto the head unit. Chromecast's screencasting works PERFECTLY for this purpose and I'm super happy with the performance
The problem comes in when I get to the fact that the chromecast can't cast my screen without an active internet connection. The dongle needs to download the casting app each time it starts, apparently.
My plan is to purchase a freedompop hotspot and go for the free 500mb a month plan, as the casting software for the chromecast is very small. The LTE connection on my phone is not an option because i'm not able to root, as well as whatever complications would arise from being the device broadcasting a network that it has to connect to.
What I'm trying to avoid is allowing my phone to consume data over the wifi network that it will have to connect to on order to cast its screen to the chromecast and my head unit.
I'm open to other creative solutions if you have any ideas. Miracast was an option, but after attempting to use a roku stick for that purpose, i've found that miracast and the Alpha aren't really good friends yet. If anybody knows of a miracast dongle that works well with the alpha, please share!

Video streaming over tethered connection

Hi, I hope this is the right place for this question.
I'm looking for a video streaming app that will work over a tethered connection i.e. one phone tethered to the other, without a separate wifi network or internet connection. The two phones will be the only devices available. One phone will act as the video camera outside in the cold, the other will be for monitoring the video inside in the warm.
I've found that most wifi-enabled apps of any sort won't work in this scenario.

Hotspot

Hi
So my situation is that I want to use my phone with android auto in my car however my phone is not compatible so I've stuck one of my old phones in the car permanently connected to android auto. When in the car i share my 4g connection via hotspot so I can stream from Spotify amd download map data etc. However I would like to know if there is a way to share my phone reception... What I mean about that is when a phone call or sms comes through to the phone can I wordlessly share this with the car phone so they come through android auto.
Thanks in advance
James
