Received my MHL converter today - first impressions pretty bad

As the title states I got the MHL today. Output to a 73" 1080p DLP, 55" Samsung LED 7000 series smart TV, 50" 1080p Panasonic Plasma, and 39" 1080p westinghouse LED all produce similar results... and if I do say so myself, it's really bad.
Lets see where to begin:
The Good:
-Watching 1080p content from local or network storage produces a pretty good picture
-Text is sharp, webpages look great
-Phone charges while mirroring
The Bad:
-Audio output is descent at best through HDMI, when connected with a very nice surround sound decoder it only decodes as "multi-channel", so DTS and other streams are not preserved on output
-Lag. And let me say this again... LAG. Don't even bother playing a game, it's unbearable. The phone experiences no lag while mirroring, but the output is about 1/3 the framerate.
-Lag on movies. On every TV the lag was exactly the same, whether I hardware decode or software decode the lag is present. Youtube videos look laggy even.
-Netflix does not properly mirror. I presume this is related to HDCP or copy prevention, but streaming HD content to the phone produces a nice widescreen image on the phone, but the output to the connected monitor is pure crap. Take a nice 720p HD movie, compress it using the bitrate of a low quality MP3, transmit it via AM radio to your least favorite country somehow, and then watch it on a ****ty color TV from the 1980's. This is my experience with Netflix output. Also, you can tell it is not "mirroring" because when you tap the screen, the position slider appears on the phone but not the TV.
-Cannot turn screen off while mirroring
All in all, I'm somewhat pissed off. In its present state I would have preferred the phone not support HDMI. I would accept this as a "Oh hey the phone doesn't technically support MHL HDMI mirroring but we hacked it and look what we can do" but this is definitely not a finished product to advertise. Anyone else experience similar problems? Anybody have HD output with no lag? Maybe I have a defective MHL adapter/phone?

I think you may have a defective adapter/cable. I got the adapter tip today and most of your cons were nonexistent for me -
Audio Output - I don't know much about audio but I have a 5.1 surround sound setup and it worked perfectly.
Lag - I had 0 lag. I played a racing game and watched a few episodes of Breaking Bad (MKV so the phone was working hard at decoding it too) and I had no lag.
Turning screen off - I see this as a pro since you cant accidentally turn it off while mirroring
But this brings me to my point about netflix...
Netflix has been horrible with MHL on my last 3 phones, including this one. If I try to watch a 16:9 HD show on netflix through MHL, it plays fine on the phone but becomes 4:3 on my 16:9 HDTV somehow. I don't know why this happens, but if there was a way to make it mirror exactly what was on the screen, that wouldn't happen.
I'm actually quite pleased since the signal is very solid with this phone. With previous phones, the signal constantly dropped and reconnected. I tried every cable but it was a no go.

The Netflix I don't believe is the phones fault directly, I think it has to do with Netflix restricting output. As for the lag, I will return the unit as defective if I can and get another one. Hopefully that's the problem, the lag is incredibly noticeable for me. Audio wise, it's not bad, but I don't see why it can't just output (or at least give as an option) uncompressed audio from the source. My main irk is the framerate I've seen, hopefully it's limited to this unit. Anybody else experience lag or more importantly not experience any?

I ran Netflix ok.. but same ratio issues as above... didn't look great but was ok. Any regular video files looked great.. but I had to order 2 adapters before I got the right one.

I also received my MHL adapter in the mail today. I like the picture quality and sound quality on my 42" 720p plasma, but I am wondering if it supports headphone port output somehow.

I got a connector also, but does seem to work with my monocable NHL,

I have a Samsung mhl and it works great

I just used the official Samsung one today to deliver a training for a few new hires, and it worked perfectly. I had a full 10 slide powerpoint, afterwards I opened up the camera app and used the connected LCD screen as the viewfinder.

Issues with the MHL adapter lag, and possible fix
I have noticed similar problems as the OP. About an 1/8 of a second lag when trying to play SNES. For those of you who wanted to retro game with a bluetooth controller (like a PS3 sixaxis) I was able to get it to work. It could be my TV, but I got the lag down well below a second, enough so that you can play a game like donkey kong country and dodge opponents. The game plays at 30Hz which isn't the best frame rate, but fine for SNES.
The TV is a Samsung 1080p and there are two options that I enabled that seemed to help; video game mode, and BD mode. I don't think the TV should matter but I thought I should mention this. After much tinkering I realized that the phone is sending two different streams instead of exactly mirroring the phone's own stream. I think this is the case because when I was playing with settings I noticed in some cases it would send a landscape view to the TV when the phone's own display was in portrait mode. There were a couple other things that indicated that this is the case.
The Fix:
Anyways using a third party app like Titanium back up you need to freeze almost everything, anything that is not essential to running the game of your choice; this includes things like Verizon bloatware, Samsung bloat ware, s voice, maps, Facebook etc. You also have to turn off things like wifi, GPS, sync, etc. I also enabled force GPU rendering in the developer settings. Make sure you don't have a live background running. I also overclocked my phone to the max with setCPU. Also if you use an app like nova launcher you can make a back up of your settings and app placements which you can restore to keep your icon placements. I realize this is not a very viable fix, but this seemed to work for me.
End Fix
It's a pain, but worth it if you want a portable retro game machine. Samsung or someone at XDA needs to look into fixing this because I am pretty sure it is a software related issue. I hope anyone who bought a MHL adapter and wanted to retro game finds this useful.

So with the guys who have good results where you ordering it from.

Hey just an update for anyone having issues such as screen flashes and lag I did a little more research and found in Samsung documentation that when connected to hdmi the s3 disables the output when a text or phone call is received but this was not implemented. I found that the device still checks for phone use and texts when connected to mhl. I actually had random screen flashes at set intervals on my TV! I disabled the phone and sms and this seemed to stop the flashing and help with some lag. I also noticed if you restart the device with the MHL to hdmi cable inserted the connection is a tad better and it also fixes screen flashes. I wish the damn thing worked and I have already replaced the MHL to hdmi cable twice now, and the slight lag (noticable when gaming) seems to affect a lot of people. It could be a problem with the actual device and not the software which would suck

Streaming bluetooth audio while moto 360 synced question

Hello,
Just wonder if I am alone on this one. I noticed today that when I stream music on my note3 to my car while being connected to the moto that the must quality dropped. I use Google play all access paid feature. This has never happened before when I didn't have the watch synced.
Has anyone else heard of this? I am going to try to use spotify tonight and see if it was a Google server issues or my signal.
Thank you

Custom rom?
It's possible the music streaming is maxing out the bluetooth and the watch updating itself is just too much, but for a Note 3 it should be no sweat...

I havent noticed any problem like that... you sure your audio quality from the play music itself isnt lower?

same here, no problem..same situation, same quality

Does anyone know how to NOT have Google music on the watch? I took it away from notification on the wear app but it still happens. I don't want to see what is playing or skip to next track on the watch.. For this reason and i'm sure its killing battery lift if I go on a long trip if it updates after each song.

I haven't noticed any problems. Nexus 5, All Access, with my BT speaker and in my Mazda, it works same as before I had the watch.

I notice the audio from my car cuts out or stutters. This is when I have my watch connected to my phone too. I never had this issue prior to the watch.
I'm using a LG G2 running Optimus 1.3.2 rom

On the latest PA Beta 2 Rom on my Nexus 5 and no issues connecting to my HTC Stereo clip. Used with spotify, poweramp, n7 player and other players as well.

I'm having an issue with audio dropping out and being interfered with too. Oneplus One, Moto 360, Audi Bluetooth audio. Very frustrating. Sometimes I can hear the quality level of the music change when it drops out, almost like it's trying different bitrates or codecs to fix the issue.

Least I am not the only one, but mine never actually drops. But I can just tell the quality go down. Like going from 256kb to 128kb..This is even music that loaded on my phone, Not spotify or Pandora.

Are you using ART or Dalvik runtime? This was happening to me after switching to Dalvik. Switching back to Dalvik solved it.

I noticed the audio quality drop as well on my HTC One m7, stock rooted. I first noticed it dropped slightly after getting a bluetooth obd reader but it wasn't enough to really worry about. Then, after getting my moto 360, the quality dropped even more to the point I had to stop using bluetooth for streaming music and use an auxiliary cable instead. So, it seems it's just using up too much of whatever bluetooth bandwidth is available so the audio quality drops in order to compensate.

I have this problem to, using a LG G3 with ART, I have to disconnect the moto 360 from the phone to have a good audio.

No problems here with my Note 3 connected to my M360 and Ford Sync.

This is a question I keep checking on too. Seems like the common factor for people not having issues drive a Ford, using Ford Sync.
I drive a Toyota [emoji107]

I've switched roms on my Lg G2. Im currently running Liquid Smooth (with ART enableD) and have not had any issues. I am streaming from my Google Music and bluetooth is connected to watch and my car. Cutting out and stutters are gone.
So may be ROM specific?

Small update; connected to a a Pioneer AVH- 200BT and the watch with no issues.

I'm having the same problem. My Moto 360 is constantly connected to my stock Moto x (original). When I stream audio over bluetooth from my phone to my car radio, the phone and radio randomly lose their connection to each other. Sometimes they appear to be paired and my phone says that it's playing, but no audio is coming out of the radio, so I have to cycle the phone's bluetooth off & on again to get audio working again.
Edit: I just found a thread on Motorola's official forum for the 360. Matt, the forums manager, thinks that the bluetooth capacity of the phone is being overloaded.

No issues with my note 2 connected to watch and my Hyundai car audio

After some more testing I still have the same issue, Works perfect with watch disconnected. There isn't some kind of widget or toggle that can discount/reconnect only the watch is there? without going to the wear app.
But I did find this, it has something with the music controls on the watch. I was uninstalling Spotify and reinstalling it. Before the watch was synced knowing I have the spotify app, I was able to use the app and play perfect audio. Of course this doesn't last long before the watch kicks in. After doing more re-search we CANT disable the controls on the watch no matter what. Least with the current version we are on, Hopefully that will change.

10.5 Bluetooth issues

I bought a dknight magicbox Bluetooth speaker for my tab S 10.5. Podcasts and music streaming are fine, but streaming video with hbo go and max go I get audio lag and choppy video. Games are hopeless because of huge amount of dropped frames. Youtube is okay, though.
I thought hmm I guess that's why it costs $30 and not $50 or $100 like the other Bluetooth speakers. But I tried it on my iPad 3 with hbo and it is fine. I thought okay maybe the hbo app for android lags, so I tried it on my nook hd+ it is fine. Played fast and furious 6 very heavy action and no noticeable dropped frames.
The other thing is the tab cannot see my vizio 5.1 sound bar at all (does not show up after scan), but my other devices can see it just fine.
I've tried two different TW ROM and a cm12 ROM. Same result.
Anyone else has blue tooth issues like mine?
Oh yes I should say I am using 5Ghz Wi-Fi to avoid conflict with Bluetooth. That's not the problem.

The other thing I notice: I have touch sound enabled (tab plays a sound when you touch something on screen). Every time this happens, it causes the speaker to (beside playing the touch sound) make a humming / buzzing noise for like three seconds. doing the same thing on the nook hd+ does not produce the same noise. Do I think there is some kind of interference the tab is sending out to the speaker.

Bluetooth streaming issue/ suttering

When I connect Bluetooth to my car and try to stream music it start stuttering/ skipping like crazy, every second or so. I've tried it with multiple apps, Spotify, play music and YouTube same effect. Seems like Bluetooth can't handle the bandwidth. Never had this problem with my Nexus 5.

It's been working great for me. Tried it with my VW Passat, Bose Soundlink Mini, and another Bluetooth speaker. No skipping or audio delays noticed. Usually playing Play Music, YouTube, or iHeartRadio.

It hasn't been as bad a you describe but I have noticed some stuttering. Not enough to ruin my experience, though.

I got phone on 10-21. I stream Pandora all day in my work truck to a jbl change 2+ and have my bt ear piece for calls connected all day. I have not had one issue

Mine did it the first time I ever used it in my car, and it was unbearable. After day one though, the issue self resolved and I had no problems. I actually noticed it first using navigation over bt

Yep. I got this several times. Turning off/on Bluetooth was the only way to fix. Not ideal when doing 70 on the motorway.

Same problem here, it makes bluetooth unbearable in my car. ONLY my car, as I don't have any stuttering on other bluetooth devices. Never had a problem on my Nexus 5, only the 5X.
Edit:
For clarity, I am full stock, not rooted or unlocked

I'm having the same issues. It seems the worst when I have Waze running while beyondpod is playing. I don't have guidance enabled, so Waze shouldn't be playing audio.

After streaming for a few days, I don't have this problem anymore. Weird, but I'm glad it's working now. Try what someone posted earlier, just turn off and turn on Bluetooth.

That didn't solve my issue. Rebooting the phone did, however. There must be a memory leak.

There is a issue opened on the Google code page. I'm not skilled enough with adb to capture the logcat. I am not allowed to post links so just add

I experienced some stuttering over bluetooth in my toyota camry. Will test it further.

I could not reproduce the stuttering issues again until today when I was streaming music it decided to stutter as I read an email. Rebooted phone and it was fine.

Up the thread.
I just bought bluetooth earphones, I thought they were defective, so I replace them, but i got always the same problem, the sound is stuttering. And after some seconds, it simply goes blank, no sound at all. :/
I tested them on other smartphones and tablet, and they are working great.
I also noticed that if i put the nexus 5x really closed to the earphones (1 cm), it's working nice.
I contact Google, but they kept saying i have to contact the earphones manufacturer (Aukey). But it's clearly a bug with the phone.
There is just one thing I didn't try yet. It's to wipe the phone and flash the last android image (i read somewhere some guys fixed their problem doing this, where ota updates didn't).
Anybody got information or solution?
Thanks

Bluetooth music stutter

I've had some stutter with music playback through my bluetooth speakers. I have 3 and it happens with all of them. I have a subscription to Spotify and noticed it there. I tried Play Music and it stuttered too. I put a few albums on the phone to see if that made a difference but it didn't. It's not bad, just here and there but enough of a problem that I'm not going to put up with it. I did a reset but that didn't help. If it's a bad phone, I'll return it. I would think if others have had a problem I'd see someone commenting on it. Has anyone listened to music via bluetooth and had either an occasional stutter or a smooth experience? I've used the speakers with my Moto X and they've been good so I know they are ok. I appreciate any comments. I love the phone but need my BT tunes.

I've never used Bluetooth and have not had an issue here or there. It happens with every device out there. It comes with the territory of using Bluetooth.

I have to disagree, my xperia z3 was awful for this. So far I have not had any issues with my Pixel XL and I use it for my 1 hour commute twice a day aswell sporadically throughout the evenings/weekend. Could range be an issue for you? or perhaps a crowded 2.4GHz band?

I have the same issue. I just assumed it was the crappy headphones I use. It happened on the 6p I had. Seems it happens mostly when I put my hand on the glass window like I'm causing interference

Thanks for the reply, my phone is a few feet from the speaker and there is a stutter every few minutes. I'm at home, not a lot of network traffic. Apparently not a problem with others judging by the lack of comments. Thanks again.

If you have any xmas lights or similar (we have decorative LEDs) close to your speakers or between your phone and the speakers these can have an affect. I had to move my WiFi hub last Christmas as the Xmas tree was causing havoc!

I have the same issue. Rare but it does exist. This phone or the O/S is noted for B/T issues.
I have SkullCandy headphones and a 2015 Huyndai Veloster Turbo and it happens on both.

Listening to music on BT headphones.
I've got a Huawei watch attached over BT. As long as I don't add a 3rd device playback is fine for me.
If I add a 3rd device, typically either a Mac or PC (e.g. Surface) then every 30 seconds or so there will be a stutter. Even though those devices aren't sending audio, there is enough chatter to cause an issue.

Yep - BT audio skips with my BT headset and 3 different BT speakers. All of these BT devices worked perfectly with previous phones, and I listen to music quite a bit, so it's truly a accurate comparison.
I have contacted Google and they have only suggested the most obvious things - none of which had any affect. Tossing cache, tossing all pairing and re-pairing. Latest was a Factory Data Reset and I just don't have the time for that now. Other Pixel owners report that same BT issues - some with pairing (which I don't have) and skipping/dropping signal.

I've found that 2 of the 3 speakers I have stutter, the ue seems to be OK. My son's Pixel had the same issue so it's not a bad phone. I guess I need to decide if I'm going to put up with it or not.

A cheap chromecast audio would fix this for you

I've noticed similar issue. Bluetooth stuttering. S7 never did it. Pixel xl does. Reboot phone fixes it for a while.
Might be Spotify memory leak. Not tested if Google Play also does it but will test that.

Same issue here with the bluetooth in my car

I have noticed the same problem a couple times, I cannot pin it down. I though it was the speaker, which is a fairly cheap one. I will test it more and see if I can find a pattern?

I just think BT for Android needs to be worked on. Same behavior on Nexus devices.

As someone pointed out a while ago, turning off wifi seems to stop the stutter. That causes you to keep an eye on your data use though. Hoping for a fix.

I will try that but I stream music a lot, that would seem to run up a lot of data.

Yea, that's not a very good solution.

My old headphones were BT4.0. the new ones I just got are 4.1. so far my newer ones dont stutter when I cover the glass. I still get some stutter here and there but i think that's just interference.

I have not experienced any issues with stutter or connectivity when streaming to my Lexus GS and paired to my LG watch - while using GPS/Navigation/Waze. I came from the HTC 10 which had MAJOR issues with this combination.
