HDMI Adapter Problems/Flickering Output

Hi
I just recieved my Adapter but something seems to be faulty on this,
when I connect it with several HDMI cables the mirrored picture starts to jitter or the connection break for a few seconds.
The cables are not decoupled and not really expensive, I have no other HDMI device to test them but I dont think that they are buggy.
The TV connected to is a Philips PFL8404
Some suggestions what I'm doing wrong?
The GT is rooted and on stock ROM.

i have the same issue. i tried two different hdmi cables and two different hdtvs and the issue is still happening. at this point i think its a defective adapter. Im gonna exhange it.

I had a similar issue back when I had a Xoom (which I ended up returning cause of weight). I am debating over ordering the adapter for my Tab, and if they are doing this, too, then I'd be fairly dissapointing. I always figured maybe the Xoom had a loose connection or the cable sucked, but maybe it's something else?

Got my HDMI adapter for my Galaxy Tab 10.1 yesterday also. It flickers and looses connection so much it useless. I've tried several new HDMI cables, and 3 different TVs. All flicker and blink. I'm sure it's a bad adapter. Will be returned shortly.

i would like to see someone post positive things about the hdmi adapter, have been thinking about getting one, but so far all these posts make me believe that its now worth it?
thanks

recieved a second adapter and still the same, seems to be a problem with the GT itselve or with some drivers build in, may the root crashed something, will trx out.

just ttryed another 40 bucks cable and still the same, dont think thats a hardware fault by the adapter. The only thing I can test now is to unroot to stock. Will test later and update.
UPDATE: Unrooting doesnt work

it doesnt seem like the people with the verizon hdmi adapter are having this issue. I wonder if its made differently?

I just received my adapter from Verizon and I can confirm the same issues so its not related to where you buy it.
Anyone notice what the status of their battery life is when using the adapter? Mine glitched the first time I tested it out and I had just taken the Tab off the charger. I kept getting a notification to unplug the Tab because it had reached 100% charge, which I haven't seen before. When I tried it later in the day it wasn't fully charged and it seemed fine. I haven't had a chance to try it longer than 10 minutes yet so not sure if its battery charging related. I know it doesn't work without a power supply so maybe once the Tabs at 100% it rejects power and cuts the HDMI off. Just a thought, I may be wrong.

I just tried it with 30% battery life and still having the same issue. does anyone have one that works?

Yeah I tried watching a movie on mine last night with about 70% battery and it switched from TV to Tab then back to TV about every 5 minutes.

I don't have an HDMI out cable, but I was wondering if you guys were plugging the charger into the HDMI, or if you were using it without it. I'm curious because I saw a review about it stating they needed the Charger to be plugged into the HDMI to get it to work.

yhea thats right you have to plug the wall charger in otherwhise it wont display anything at all, our problem is the faulty result whats on the screen

Wow. I was just about to order the HDMI adapter from Sammy (I stubbornly kept waiting for BestBuy or Verizon to get one in stock). But seeing all these problems, I wonder if they're having quality or other issues, and hence why it's not hitting shelves yet.
Does anyone have a feel for whether all seem to be defective, or if these posts are more representative of the adapters that are defective? (guessing from those saying they've tried more than one, that there seems to be a general problem with the adapters).

Okay I have a 10.1 galaxy tab wifi and a home made dock from a 7 inch tab and 10 inch tab dock. Using the oem power adapter that came with my tab. With my hdmi dock I watched a movie on amazon instant via the browser And I rented a movie from google. Both movies played perfectly through my 50 inch plasma tv via the hdmi dock.. I can tell you that movies would not play from google untell touchwiz update. but after the update I have had no problems whatsoever playing any content via hdmi. Also I don't know if it makes any difference but I have never rooted my tab. Good luck guys I don't know what's going on I hope you figure it out.

Hey mopar. Is your tv a 1080p? Both my hdtvs are 1080i so im wondering if thats causing the issue. I think i read somewhere that this tab outputs in 1080p. I dont think its the video player because it cuts in and out without running any programs. Its like every 30 seconds the tv screen will cut out go black and then come back on. its basically useless.

I believe my tv is the lower of the 2 not sure though.... it's definitely not a high end tv but it is new..w

my tv is a 1080p

I just got the adapter today and haven't had any problems with it so far

I just got the 7 " docking with HDMI out and it works like a charm, so it seems to be a production problem with the adapters. Brought me the 10.1 dock to put the piece on the 7 " base.

Car Charger Spec Query

i am looking for a decent [working, cheap and quick charging] car charger.
I know I'll need at least a 1amp [right?] however i have seen a few that charger at 1amp and 2.1amp
is it going to ruin my battery if i use 2.1amp?
anyone found and goodies out there?
thanks

I second this request, i've got a few generic car chargers from older gear that i've tried with the galaxy nexus. So far they all come up as charging via usb, and so the phone loses power when the navigation/bluetooth/etc/etc is all on. I understand the power requirements, and looked into the data-cable soldering malarkey solution, but my soldering skills in the "fire hazard" class at best so i'd much rather an off the shelf solution.
I'd be very grateful if anyone could point out a car charger that they know/strongly suspect works fine.
Cheers

so the same car charger i've been using for my nexus one for navigation won't work with the GNex?

No, but it won't charge the battery faster either.

More amps is fine. Your phone will only pull what it needs, even if more amps are available.

Also be aware that even though some car chargers state they can supply >1A current, some phones (like my Nexus One and Galaxy Nexus) will not recognize it as a high speed charger.
Smartphones and other devices check to see if the data pins (D+ and D-) are shorted or have a specific resistance before activating high-speed mode since normal USB data specifications say that devices should only pull <500mA from the port.
I have this one: http://www.amazon.com/dp/B002IW79ZC/?tag=68656c7064757-20, which is supposed to supply 1A, but I when I plug my phone in with a normal USB micro cable, it says it's charging through "USB" vs "AC", where "AC" is the high-speed charging.
I've made a hacked cable adapter, though, which has the data pins shorted. When I use this with the car adapter, it charges at full speed. You should check to be sure that your phone is fully utilizing the charger by going into the Settings > Battery menu.

Hi all,
I thought I'd share how I've gotten on. There's a 2.1a charger that maplins sell that I thought might do it, but alas no - still comes up as "Charging(USB)". I know taFFer solved the problem with a little solder, and a lot of forum threads also suggest the same fix, but the last time I picked up a soldering iron actually ended with a trip to A&E (long, embarrassing, story) so I was still keen to find an off the shelf solution.
Anyway, after reading a lot more forums, I found a few different people recommending the same motorola charger. Amazon UK sell it, so I stuck in an order. Details below:
MOTOROLA P513 MICRO USB IN CAR CHARGER, £5.45*
http://www.amazon.co.uk/gp/product/B000S5Q9CA
*above item(s) sold by and shipped from Keep Talking
It arrived today and sure enough simply plugging it into the car results in it appearing as Charging(AC). I've not gone on a long enough drive to know about charging speed when gps/bluetooth/etc is all going, but if anyone else is after a cheap car charger that just works without hacking your own cable I think this is the one.
Cheers
***EDIT***
After criss-crossing the country over the xmas period i can tell you this charger is working fine for me. Even when using all the gps, bluetooth, screen on, etc that i can muster (while still driving straight!) the phone gains power and would often come out the car more charged than when it went in. The charger has one annoyance - they've built in a blue led to the charger which is lit up the whole time the thing is plugged in and thats kind of distracting, i don't really know what they were thinking with that, but otherwise i've no complaints.

Thanks a lot for the news mate. I'll be getting one soon! Will you be able to post again when you find out how the charger works with gps etc. Thank you!

Anyone know if this charger works with the galaxy nexus (detected as AC?)

For optimal charging, you need 1000mAh output. How much does this charger output?

MHL adapter issues

So i picked up an MHL dvi adapter off of the egg.......
http://www.newegg.com/Product/Product.aspx?Item=9SIA0PG0822857
It is having terrible flicker issues when using 4g, if i hit airplane mode it works really well but i cant do that for obvious reasons. Thoughts?
I have tried different kernals with no luck.

Did you connect the power plug?

Most (afaik) don't function without power being applied, but this definitely sounds like a power issue. I assume you have it plugged in to a USB port on either your TV or computer? Try using an AC outlet charger.

Yes the the power has been applied, i have tried both a computer and a 1 amp charger with the same results.
I also have a MHL HDMI cable that works fine.
Only the DVI one flickers. and only when other things are running on the phone. turning off 4g causes the flicker to pretty much go away.

I could get it work ONLY with the official samsung charger. I had an iphone and a HP touchpad charger both of which didn't work.

I have not tried my official charger yet however..... my issues are directly related to 4g...... when its on flicker is bad. if i toggle it off it pretty much does not flicker any more. Not sure if its a power issue or what.......
Thoughts.

I believe this has been reported before with Verizon Nexus. GSM version doesn't exhibit this problem AFAIK. It must be an issue with the CDMA version.
As for the solution I can only suggest you try the original Samsung MHL cable or another brand and see if it makes a difference. I use the official cable with my GSM model and no issues. I do however get random disconnections during use, which can be fixed with a unplug and replug.

HDMI not working anymore

My phone is rooted & I am on the original firmware that came with the phone.
I originally was using a cheap mhl/hdmi cable that I got off ebay. It worked great until the other day. I assumed that it was just a cheap/broken cable so I picked up the Samsung Smart Dock. Unfortunately, that doesn't work either so I'm assuming something is wrong with my phone.
I took the battery out & did a restore/reset to factory conditions. Still no luck.
Any ideas on how to get this working or do you think the problem is the phone's hardware?
Thanks!

Is the USB port working at all on your phone? It's possible some of your pins went bad in the port.
In my experience, sometimes the port can be nick picky about with the MHL. But I was using a generic HML adapter and a 5-11pin usb adapter. If you know someone else with a GN2, you may want to check your stuff with their phone just to make sure it's the cable or dock and not the phone. You can also use a GS3 too.

Not familiar with the Smart Dock. Is it 11 pin and not the older version 5 pin, I would think to confirm this?
I purchased the Samsung Dongle for hdmi and it worked great, just remember to also plug in power as well.

Thanks for the responses, but still no luck!
@lovekeiiy - Unfortunately, I don't know anyone with a Note 2 or S3, but since two cables don't work (including one that used to work), like you, I'm guessing that it is the port. I guess that I'll have to take it back to Sprint.
@q711179 - Yeah, the Smart Dock is made specifically for the Note 2. The phone charges and connects to the computer perfectly so something having to do with the MHL connect is probably on the fritz. And, yes, it was plugged in.
Anyone have any other ideas before I head to Sprint?
Thanks again!

maybe one of the Sprint employees will have a GN2 or GS3 you can test your cables or dock with.
I'm not saying it's not the port. I would just hate to go through the hassle of exchanging the phone and it's still happens to be the cables or dock. It's possible you could have gotten a bad second cable and dock; that's some bad luck if true.
Thus, that why I ask if you're able to connect the phone to a PC or charger. I assume an HML cable connected to either should trigger the USB memory storage and charging on the PC and charging with the wallwort or car cigarette usb adapter.
In my experience, I find with pin adapter and HML converter box, it tends to be nick picky at times.
On a side note, I don't like how using these adapters don't really charger the phone. It's just a slower drain. I would rather have to use regular AC adapter. I guess once could try to use a more power USB wallwort with HML adapter. But I digress.....

@lovekeiiy - Great idea to have someone at the Sprint store check out the cable. I really hope that it is the cable and not the phone. Thanks for your trying to troubleshoot this with me. And, yes, I really wish that MHL cable didn't drain the phone!

I had a lot of glitchy issues when using standard a/c charging units the one that output .5 or .7 amps even the 1 amps with the mhl adapter. I use my Nexus 7 charger which puts out 2 amps and all the glitchy issues i had went away now the output to the tv is solid.

Thanks for the idea. I tried a bunch of chargers, ranging from .8 amps to 2 amps, and no luck. The frustrating thing is that the Note 2, says that the HDMI cable is connected, but there is no output. I've tried several different monitors to.
Since the Sprint Store is a small hike for me to get to, I won't be going until this weekend so if anyone has any other ideas, please let me know.

the phone says it's connected? It's possible there's a HDCP issue. Have you tried a different TV? Don't test with Hulu or Sprint TV, they both disable HMDI out. You should be able to see something if on your homescreens.
Unfortunately, there are only so many TVs that have HML, mainly Samsung. Other TVs, you need that HML adapter. You may want to try the phone at a friend's TV or local electronics store. You may need to bring a external USB battery to power the HML adapter if you have an HML adapter or your phone's charger.

I've tried it on a computer monitor (where it worked previously w/ my Note 2 and it just stopped working for some reason when I was using a cheap MHL/HDMI connector that I got off amazon). I also tried it on another computer monitor and on a Motorola Lapdock. On all monitors, the phone shows that the HDMI cable is connected when using either the Smart Dock or the cheap connector, but there is no picture when I am on the homescreen (or when on any other screen).
I know that my HDMI cable that I connect to the Smart Dock works since I tested it w/ all of the above monitors with a Raspberry Pi.
I can power the phone & connector with the Lapdock so I'll give that a shot at an electronics store.
Do you think that it could be a software issue? Should I try a new ROM that supports the MHL/HDMI out?
Thanks again for all of your help. I really appreciate it

I would try a different rom if you can. I thought you were running a stock rom. I've been using stock the whole time. I'm rooted. I'm currently running a stock deoxedized. I haven't used the HML in a while, but I will try it later to make sure it's working.
If you're able to charge the phone while using a HML cord or adapter, then it's either the firmware or the USB port is borked, but not completely.
Going to electronics store was suggested because those TV should all have the HDCP that the phone could be looking for. I don't know how your old TV or monitors are, so it's possible they may lack it. Sometimes, it's just the handshake, and just turning off the phone (just hit the power botton on the phone, don't actually shut it off) or TV, and then turn them back on can resolve the resolve the handshake. I've heard of this for home theater PCs or other devices in that area.

I'm on the stock rom, but was wondering if switching it might help if it is a software issue, but since I already did a factory reset, I sort of doubt it.
I'll try the electronics store next week. I have to work this weekend, and I don't go near an electronic store during my commute. I really hope it works.
Thanks again for all your suggestions. I really appreciate it. I'll report back next week.

I hooked up my GN2 to the HDTV, and was working fine.
Not the best video, but you can see phone with the 5 to 11 pin adapter, generic monoprice HML adapter. The comparison thing about it, keeps me from getting propped with copyright infringements.
I had the same thought your factory reset. I also was thinking maybe you downloaded it to reflash it and maybe your download was corrupted. Obviously, I have no idea if you flashed a different rom after rooting. If you didn't, then flashing a different is not likely going to help. But at this point, I'm not sure what you have to lose; it should be noted, I don't know how many flashes you get before the Sprint or Samsung get pissy. You may want to run flash away if you have to replace your phone. I never used it myself.

Thanks so much for the video. I wish that my phone could do that. I just got back from BestBuy and tried the phone on a number of TVs using a 5 volt 2 amp power source, and no luck. So, I'm sure it is the phone.
I only rooted, and did not flash a new ROM so I'm going to use Triangle Away and bring it back to Sprint.
Thanks again for all your help!

My hmdi out is not working either it used to work and would play games off my phone on the big screen but now nothing, just the "HDMI cable connected" prompt on my phone. Tried rebooting, ,etc etc...
I am running custom rom/kernel so I fear that might have something to do with it...I will try triangle away before i try more drastic solutions I suppose...

You may want to try a stock rom and kernel. I don't suspect the kernel, but it's possible the ROM doesn't have all the drivers or something to have a working HDMI.
---------- Post added at 05:15 AM ---------- Previous post was at 05:14 AM ----------
and Triagle Away isn't going the HDMI situation. It's a tool to reset the flash counter so one can avoid a warranty from being voided for flashing too many times.

I didn't think triangle away would help (and it didn't) but thought I'd give it a shot anyway...
I'm happy to say I got it working by disabling the exynos exploit patcher and rebooting...it's back to working perfectly now. I actually uninstalled that app bc my kernel includes its own exploit patch

You solved it! It was the exynos exploit patcher! I enabled it and didn't use HDMI for a few weeks so the thought never crossed my mind. I just disabled it and HDMI out is working again. Thank you!!!
What kernal & ROM are you using?

Yay! Lol glad I could help I was ripping my hair out trying to watch a movie last night.
Im using macks rom 4.0 with latest Perseus kernel 32.1 Andreilux mentions in the changelog for version 31 that it now includes samsungs official fix:
forum.xda-developers.com/showthread.php?t=1927852
"Removed my own security fixes and replaced them with the official Samsung one. I guess it can now be disclosed: exynos-mem was only one of multiple entry-points for the memory exploit. We discovered the s5p-smem exploit ourselves back in December but kept it quiet, I fixed that one back in version 29.2 without mentioning. Nobody was secure from a smart exploiter up until then, SuperCurios or Chainfire's software fixes are also just patching a single hole in what is a Swiss cheese. Kernels >v31 and beyond stock LLA are now the only truly protected ones"

Thanks for the response. I'll read up on the kernel & ROM and probably load those up tonight.

[Q] car charging for sm-t210

hi, does anyone have a solution. when i plug my note 3 7" in it doesn't even register as being plugged in. do other roms correct this problem? or is there another solution. I've tried different plugs with outputs that say they are the same as the wall outlets (which charges fine)
This is a major problem as i only got this tablet to replace my car stereo. I have everything done and wired up, but now I have a tablet that can't charge while in the car.
Any solution and I would be very grateful. thanks.

Chances are your adapter isn't putting out enough amperage.
What is it rated for? The tablet really wants 2A, though it seems to work ok with 1A. That said, it also seems to be a bit funny about cables.
I only just got mine yesterday, so early days, but have noticed some charging weirdness.

My charger says 2.1A and is capable of charging an iPad. I tried 2 different cables, both data cables but they both work in a wall charger.
I was hoping someone would tell me to update to CM and all would work fine because there are some odd UI glitches in the touchwiz, especially bluetooth disconnecting.
I dont want to root and ROM unless I know these problems will go away. I will return this thing if the problem is unsolvable. I have about a week left.
