I have been using an OTG cable (which was not specifically purchased for the N7 - I had one from another device) and Stickmount to mount an SD card reader w/ SD card loaded with videos to view. This, generally, has been working fine, but yesterday I encountered a situation where, while trying to watch something, I was continually interrupted for several minutes at a time. Of course the N7 went into sleep. When I woke it up, I noticed that the SD reader (which has a power./activity light on it) did not get repowered. To restore it I had to unmount it, pull the OTG cable, then reconnect it.
While not THAT big of a hassle, since I was continually getting interrupted yesterday, I was wondering if this is normal behavior for N7/OTG/Stickmout.
Ok, this is a bit strange. I replaced all the hardware components (excepting the N7 itself, of course) -- new OTG cable, new portable SDHX/SDHX Micro reader and the card and it is doing the same thing. The reader has a power light on it, that remains on when it is in use. When the N7 times out (I have it set for 2 minutes), the light on the reader extinguishes as well. When I wake up the N7, the power light on the reader does NOT come back on. Stickmount reports it is still mounted and I can traverse the tree to get to it with a file manager. However, when I try to access anything on the card, it errors out.
I repeated the test with a standard USB drive (a rather small one that would not do for what I am trying to accomplish -- media storage/play to save on space on the internal "SD" card). When the N7 timed out, the light on this unit remained on. I was able to wake the unit and continue on accessing the flash drive without issue.
What the heck is the difference between a portable reader with an SD card in it and a flash drive. And, is there anyway to get the reader to behave like the flash drive.
If anyone has any insights into this, I would appreciate it!

At the point where the light does not come on, I would test removing and replacing the media in the reader. Curious if it then works.

Nope, light doesn't come on, card is not readable. Thanks for the suggestion, though...

Interesting. This sounds like the software loading the drivers for the reader are not working. Each version (over the years) of Linux has different ways to mount USB. I am not sure which method Android uses, so I am not much help. Probably someone on XDA knows the details if they will contribute. Or, you might get support from one of the popular Android OTG media sharing app makers to help explain it.
Have you tried a powered (and/or) non powered USB hub in the middle? Curious if your results would be the same.
Unfortunately I don't have one. I NEED to get one, but not yet.
Yea, I noticed the same problem when I was using android vlc to play videos from OTG mounted stick. If I paused and went away for a while, it couldn't resume when I came back. MXPlayer works better, but only because you can start playing the same video again and it will ask if it should resume where it left off, so at least there is a way to get back to where you were after remounting the stick.
If I copy the video file to the local /sdcard storage, none of these problem with sleep crop up, so it is definitely OTG that goes funny in the head.
Edit: Ive come up with a software solution myself.
Its Currently being Published to the play store, but ive attached it to this post aswell. I will most likely make a standalone Thread aswell.
Hey Guys,
I final got my Mini MicroSD Reader from the Kickstarter Campaign http://www.kickstarter.com/projects/andyfei/mini-microsd-reader-for-android-smartphones-and-ta
Problem?
When the device goes to sleep it puts the reader to sleep, but when you wake the device up, the device wont start powering the reader. Has anyone seen an issue like this? My S2 doesnt stop powering the device on sleep (Maybe because it doesnt "deep sleep"
Any Help would be appriciated

If you are using Stickmount, I'm having the same issue with multiple sdcard readers -- both normal and micro. I have not found a solution. It seems to work fine with a USB flash drive. It just seems to blow up on readers for some reason. It has been a real pain in the posterior...
I have come up with a software solution, once its ready ill share it
Ive posted the app
Has anyone seen this? It started a few weeks ago.
I use the AFTV at night.. I turn on the TV which is connected via HDMI. The TV will just be a blue screen. The power light on the AFTV will be off.. I can hit a button on the remote, and the power light will come on.. but still no video.. Nothing I can do will kick the AFTV to get it to show video until I unplug power and restart it.
From there, it will operate just fine.. until it sits idle for too long, the power management kicks in, and it wont wake up again.. back to the cycle..
I poked around the settings etc.. I didnt see anything related to sleep mode.. I have screensaver turned off.
Very strange..
Ideas anyone?

If possible hook it up to another TV. I think it might be an hdmi handshake issue. If it is you can try different hdmi cables and different ports. If you dont have another tv then turn off your tv with aftv working. Wait a short time and turn on the tv. See if the issue pops up again.

I think you are on to it. I did some more testing.. Last night I got the blue screen on the TV.. Instead of powering down the AFTV, I unplugged and re-plugged the HDMI and video came in. Its strange this suddenly started happening.. I am not sure what I can do about it.

Unusual it just started happening...are you sure you didnt switch hdmi cables or the port? Could be the latest firmware update but its doubtful because others would probably be complaining about it, and I cant think of why any update at this stage would impact cec.

I agree that is very strange.. I didnt change cables or ports.. but now that I know its an HDMI issue, I will swap some cables or something and see if it makes a difference. There really isnt anything else I can do.. On the tv, switching to another hdmi and coming back doesnt help.. I have to physically unplug the hdmi and plug it back in..
This issue has to do with HDCP and started with the 51.1.6.1 software update. See here: http://www.aftvnews.com/recent-fire-tv-software-updates-causing-blank-screen-issues-related-to-hdcp/
HDCP issues may also increase when the HDMI connection is done in a chain for e.g. with an amplifier between box and TV. The cause is often here that the amp´s do not pass through the HDCP handshake to the TV.

I just read the thread on aftvnews. It definitely seems to be my issue. I swapped to a different cable and it appears to have fixed it. The thread thought maybe the issue was fixed with 51.1.6_3_user_516012020 .. but that is the version I have and the date for the install is Aug 20..
Anyway its a tricky issue.. I guess if you get things working.. dont touch anything !..
Hi,
I have just bought and fitted a Eonon GA2114 Android unit
I have one or two issues please, and would really appreciate some help
1. When I hold the power button to shut the unit down, it says 'shutdown' for a second and the screen goes dark. When I power it on again it comes on immediately as if the stereo is switched on all along, just with the screen dimmed. (It does not boot up Android) - I should mention it is fitted into a campervan running off a leisure battery. Shouldn't make any difference I'd have thought but it is a permanent battery connection (No ignition on/off) is this a clue? I wondered if it was to do with the ACC wire if so?
2. When I do 'wake up' the Car Unit it seems to take quite a few seconds or so to 'prepare the SD card' - this can only refer to my permanently connected USB drive full of music (Via the rear of the unit) - surely this should be ready to use immediately the car stereo is on? It means I can't just switch on, and play music. Any ideas please as it is very annoying?
3. A brief one, what is the best locally stored Android music player to use please? for car use that is?
Many thanks for your hep
I must admit I am a little surprised to have no replies so far? Anyone pls?

Does the unit come with root, if it doe you could download a reboot app, most require root to function.
I don't believe these units actually shutdown, just go into standby mode, you cab check with the ENON techs.
No root as far as I am aware, a good idea otherwise thank you. I am still unable to fully power off (Or reboot) the unit. It seems to draw a lot of power and will drain the Leisure Battery for sure. I have emailed Eonon a few days ago, but not heard anything back. Not sure if they are active in any of the forums for a quicker response?
As for the USB Memory Stick with music on, I am still having the problem of 'unexpectedly removed' and 'preparing SD card' each and every time the unit is first used / turned on. Any ideas please as it's driving me bananas! thank you
I have the same unit and yeah it says powering off and it isn't powering off at all, it is even still connected to my phone via bluetooth when it has supposedly powered off!

Thanks for your reply, that is interesting. I have had two replies from Eonon so far. As I thought the ACC cable may be the culprit.
1. Unit can not shutting down completely
Please check whether you have connect the ACC wire always on BATT? If yes, this unit cannot turn off completely.
Please find the ACC control wire on the Fuse box location, then connect the ACC wire to the ACC control wire, the unit can turn on and off via key.
2. If you use the USB Memory Stick to play music? If so does yours have the delay issue as well? )Answer from Eonon copied below so far:
Yes, it will show message when you plug in or plug out SD/USB, this can not change.
But if it shows some error message that make the SD/USB would not work, would you please take a picture to show us?

I have the ACC wire connected correctly as when I turn the ignition off the stereo acknowledges this and turns off/powers down but that function is hard wired supposed to turning the unit off at the on/off/volume knob (while the ignition is on). Their answer is just avoiding the issue as the unit turns off fine with the ignition, it doesn't power down like it says it is when the ignition is on. I just turned my 'off' with the ignition on and could still connect to it via bluetooth....
I can't comment on point 2 as i've yet to rig my amps up and play any music!

Mmmmmm, thats not quite so good then. I was thinking that it might be the ACC as mine is running from a permanently 'on' Leisure Battery. I will probably pop the stereo out and have a look in the next week or so as I can't really change the battery situation (The idea is so that I don't run the starter battery down as it is a CamperVan)
I must say though that I am impressed with the sound (I have been testing PowerAmp, and PlayerPro and they both look and sound STUNNING, the standard player kept skipping for me at least)
I'm still looking into the other thing (Memory Stick) it works, but it's annoying really
I just got my unit yesterday and installed, so far very good device.
I noticed there is a setting in setup to delay shutdown for 30 seconds, and up... Maybe you are not waiting long enough for complete shutdown.
If you had the ACC wired to Battery, the unit screen would not shut off (i think).
ACC being connected to a permanent live compounds the problem as whenever ACC is live i.e ignition turned on, you can't power the unit down at all even though holding down the power button it clearly states "shutting down" when in reality it merely turns the screen off.
Thank you tiff_lee, I think that is exactly what happens in my case (Just the screen goes off)
It is draining my 12v battery rather quickly! If I was to disconnect the ACC cable will I still be able to power it on and use normally? (In my case the car stereo works from a campervan leisure battery. The idea being that you can have the radio on at any time without the ignition having to be on. Also it doesn't drain your starter battery at all)
Many thanks
ACC is accessory power. Accessory power is only powered when a key is on. If you don't have it wired to a ACC source then it won't properly shut off. Wire the ACC with the power wires and put a toggle switch between the battery and the power wires. I would think that would solve the problem.

If I understand your first post correctly you have the ACC connected all the time so yes the unit would effectively be on all the time hence the power drain. Leave the main power connected at all times as this also powers your memory, connect the ACC wire to a 12V+ supply via a toggle/selector switch and just turn it on (via toggle switch) when you want the unit on.
That aside though it doesn't change the fact that the unit does not power off when it says it is.
Hi
Been following this thread and having same issues I only have mine connected by the iso adapters and the unit doesn't seem to shut down fully,have had 1 flat battery so far after not using the van for several days on recharging battery and turning on it showed full start up screens.
Other issues are not being able to turn off the radio once turned on apart from in settings "force stop app"
No voice guidance in the Sygic GPS app.
Someone asked for a good music app,try N7 player,also Smart launcher is very good ,have it on all our Android stuff.

I have bought a Pumpkin KD-C0224 Android car unit and it's working great.
1. Have met the battery drained issue before and the Pumpkin seller suggested me exchange the "ACC" and the "B+" of the iso adapter.
They explained that the “ACC” and the “B+” of my car is opposite to the iso adapter, so I tried and it worked.
2. Maybe your USB Memory Stick is beyond the unit can support, or you can try other USB device with less than 32GB to check.
3. I have Spotify on my unit and its great, I think.
Hello,
someone did you solve this problem? I use the same multimedia Eonon GA2114 and have the same problem .In the moment extinguish my car out inscription 'unexpectedly removed SD card' Just to give contact and back contact without starting the engine again my written 'unexpectedly removed SD card'.
After starting my written 'preparing SD card' and starts from the first song. I'm tired just listening to the same song Please if anyone can help.
I have a very similar problem which has only started to happen recently on my Eonon head unit.
The problem is when you turn the unit off it shows a message saying "storage unexpectedly removed". When you turn on the head unit again it has to remount the USB drive and it starts playing music again from the beginning of the MP3. It never remembers the last play position of the MP3. This happens on various makes of freshly formatted USB sticks. Its very annoying....
I have done a full factory reset, disconnected the power and also re-connected all the cables from the back of the unit - but this did not resolve the problem.
Not really sure what to try next...any suggestions would be very much appreciated!

Hi,
I'm using the firestick on a (PC) monitor and I do not want to buy a TV for it (I don't like their quality/price).
Problem is : This monitor don't have hdmi-cec, so when the stick goes to sleep it displays a black screen to the hdmi output which prevents the monitor from going to sleep. The deep sleep option in the settings doesn't always work, sometimes it only goes to black screen.
I don't understand why sleep is so complicated to do with the stick, but I'm ready to root it in order to make deep sleep the default option (especially after inactivity).
I'm quite tech savy and it would be great to finally have a solution (not the "unplug it" one) on internet against this common problem.
Do you have any solution ? Is there the same problem on lineageos on the firestick 3 ? Is magisk a solution?
Thank you for your time!
Edit : I posted in the wrong section and am very sorry, is it possible to move this please ?
