terrible sound quality when recording

Slowly getting to know this phone better...

I found out that when recording a video, the audio quality is very bad. It sounds overly compressed, like a low bitrate mp3 stream. I have tried all different settings, 3 different apps, and it just sounds terrible with every setting. I can barely understand spoken language in some cases.

Do you know if there is any patch, update or app to make audio recording quality acceptable? When on the phone with someone, they report that the sound is clear. So it should not be a hardware failure. I have also seen some other people complain about this on the Chinese forums. I am on 19E, by the way. Thanks!

Follow-up: I just made a small test which you can reproduce yourself.

1. Get the app "Hi-Q MP3 Voice Recorder (Free)"

2. Record some audio with the default settings. Review your recording by touching the icon in the top left corner. It will sound terrible.

3. Go to Settings->Recording->Mic selection. Choose "Raw audio". Record some audio with these settings. Not only will it sound acceptable, but actually very good for a phone recording!

So the question is: Is it possible to force the camera apps to use raw audio, with a patch? Or is there some video recording app that supports choosing the raw audio input? Open camera as my best guess does not seem to support raw audio with any of its settings.

what setting did you have for your brightness? was it auto-brightness? sad that letv can only do 4 hours of screen time.
[Device Reviews and Information] Gerrit507:
It was on 40% auto brightness. Why do you think it can only do 4h of screen time? I have 4h of screen time and 1,5 days of run time and there is still 25% left. If you only use the display, I'd say it can do at least 8h, some sites say 13h of Web browsing, which is more than average.
[Device Reviews and Information] battouter:
auto brightness consumes battery, also if you always use data especially 4g that will also quickly drain your battery.

where did you read that it can do 13 hours of web browsing? i would like to know how the test was conducted.
[Device Reviews and Information] Gerrit507:
You don't have to advise me, I know that :laugh: Bluetooth and / or Wifi was also activated most of the time, there was also some Messengers running, this is how people use smartphones....

http://www.gizchina.com/2015/06/11/letv-1-x600-review/

http://www.kimovil.com/en/where-to-buy-letv-s13gb-32gb

http://www.chinahandys.net/letv-smartphone-le-one-test/

short summary in english: you can use the phone 2 days, it charges in 90 min... The battery was praised in the test.

Overall, the letv 1 is a very good smartphone in my eyes, it's very cheap(270€) and can compete with Flagships in most of the departments. You can blame the letv for a worse software at launch and still a bit crappy gps, but not at all for a bad battery, 3000mah is average at the moment, and the MediaTek X10 is very saving in standby. The camera and display are also absolutly stunning for a phone in this priceclass.

Currently you can either have a great battery with 4000mah+ or a good processor, there is no smartphone available at the moment which combines both. The first phone with 50k+ points in antutu and 4000mah will be the ZUK Z1, and it will be released in October... All phones with a battery of 4000mah +, which are available now, such as the Innos D6000 or soon the Lenovo P1 only get 30k points in antutu.

So it's a general trade off on the smartphone market, either very long battery life(3-6days) and "bad" performance OR a short battery life (1-2 days) and a "good" performance. The letv is more on performance, with 53k points constantly ,without overheating issues, like (expensive) Snapdragon 810 phones...

Not receiving text messages or whats apps?

I installed latest BB72 rom all ok and running lovely. i have a flip cover on and it was causing issues but resolved with an app called flip cover.

After three days use, now I can't get text messages and whats apps are two hours late, any ideas please ?

Switched mobile network to 3g as the preferred network, just in case.

i,m afraid that I'm going to have to sell this now.

cheers
[Device Reviews and Information] Gerrit507:
It's maybe because the phone blocks most of the apps to autolaunch on default, which means you have to start apps like What's App manually to recieve messages, or you allow them to autolaunch...

Go to Settings -> Permissions -> Manage auto launch -> Mark the apps you want

Maybe it's also a problem with your carrier... Any problems on wifi?
[Device Reviews and Information] amcslv:
Done that and not work. My google account appears sync in "settings"->"accounts" and still doesn´t show on contacts apps. The only one that the apps allow it´s a Letv account that I can not create because it demands a chinese +86 number in order to register.

I managed to import my contacts creating a vcard file from the pc and copying it to the phone but it is not the same thing cause it isn´t synched to my google account.

What is the easiest way of rooting the device in order to remove all the chinese apps ? It doesn´t make sense to sell this phone to europe with so many chinese apps... Not even an english manual... Letv could become such a huge brand if only they knew what they´re doing.

I used the video recorder and also the recorder app and the audio came out crystal clear. By the way my OS is 5S.
[Device Reviews and Information] battouter:
from what i have read from user reviews, you would be lucky to get 5 hours of SOT. the x10 chipset isn't the best for power management.
[Device Reviews and Information] Gerrit507:
Use this guide http://xdaforums.com/general/general/guide-twrp-root-gapps-letv-s1-pro-t3150782

It's also working for the X600. Install TWRP and the BB72 ROM, it's free of all chinese crap, is rooted and has (working) gapps preinstalled. You only need steps 1-6 and 10-11(for english theme). Then boot into recovery and install the ROM. Of course you can follow the whole guide, to root your current ROM and make a backup with Titanium.

Sorry but this is getting ridiculous. I got 30h of run time with 4h of display time, with gaming, spotify, whats app, surfing, youtube... and still have 25% left. I really use my phone very often and get 1,5 -2 days out of it. Believe me or not.

edit: Only for you I digged out this comparision between Snapdragon 810 and Mediatek X10, unforunately it's in german, but feel free to translate it or look for other sources. The conclusion is, the Snapdragon is getting hotter, is slower and drains more battery. After 20 antutu runs the Xiaomi Mi Note Pro (Snapdragon 810 / 3090mah) had 5% of battery, the LeTv One (Helio X10 / 3000mah) had 40% left. Which processor managment is crap now?
[Device Reviews and Information] battouter:
you must have misunderstood, 4 hours of display time is mediocre, that is all i am saying. there is a ton devices in the market that can do 4 hours of SOT.

it would have been nice if the x10 chips had better SOT's than the mt6752 and mt6753 which can consistently do 6 hours of SOT.

sd810 and sd615 is garbage.
[Device Reviews and Information] Gerrit507:
Oh my God... 26h of standby + 4h of display + 25% left. With normal usage of apps, surfing, WiFi, Bluetooth and so on not just display on.

SOT means the phone is in flight mode with no apps running at all!

My data has nothing, and really nothing at all, to do with a normal SOT test. It just shows you how much you can get with regular usage.

I hope you are able to understand this finally.
[Device Reviews and Information] battouter:
look up devices running 5.5 fhd with mt6752, better display times.

4 hours display = normal, nothing special.

hope that clears things up for you.
[Device Reviews and Information] Gerrit507:
You know what, show me any comparision of MT6752 vs. X10... You are asking for sources, but you're the only one here telling things you don't know anything about and can't proof them. Any source I found is praising the X10 for it's power saving, anyway it's NOT the CPU what drains a lot power in an SOT test, it's the display itself! A SOT test is the worst you can do for proofing the power managment of an processor, because if the screen is just on, the CPU clocking at lowest frequency with only one core and does almost nothing! If you really want to test the power managment of a CPU you need to do Antutu, web browsing, video decoding/enconding/recording...

BTW: I'm sure the LeTV does at least 10h of SOT!

And just to repeat it: 20 antutu runs and 40% left on the letv... Show me any phone with this battery capacity which can do that...
[Device Reviews and Information] battouter:
NO, the x10 on the letv cannot do 10 hours of SOT, best it can do is 6-7 hours, before it is completely dead - https://browser.primatelabs.com/battery3/92145

the best i've seen an x10 device with 5.5 fhd 3000mah can do is 7 hours.

the best an mt6752 device with the same 5.5 fhd and 3000mah can do 8-10 hours - http://browser.primatelabs.com/battery3/87062

just google devices with the mt6752 and mt6753, it is not that hard to find.

---------- Post added at 01:15 AM ---------- Previous post was at 01:07 AM ----------

just loop a 720p video on your letv with 50% brightness in airplane mode and we'll see if it can do 10 hours.
[Device Reviews and Information] fishku:
Just to be very specific, are you using the stock 5S or any custom ROM? I will try to update and see if it makes any difference. Thanks.

If I can ask you a favor, could you upload a video of you recording some youtube music video from your PC or similar?

It seems like both MIUI 6 and 7 are available now for the LeTV x600, has anyone tried them yet? It seems like they finally got audio and camera to work, too!

---------- Post added at 09:25 PM ---------- Previous post was at 09:21 PM ----------

I can recommend BB72's ROM which you can find on the Italian forum hdblog.it, it removes most of the unnecessary Chinese apps.

For rooting, I would just install TWRP recovery. From there, you can directly root (not sure if it works, though), or you can install SuperSU from a .zip file from TWRP. There are tutorials on the net, and even some youtube videos that explain it step by step.
[Device Reviews and Information] sansanc:
Yes, i already complained about this, but people (BB72 included) say it's ok. To me, definitely not ok. I did that test, significant difference! I don't know why, but even with my old phone some people would say X thing was great when in mine and other's people it was not. For example, some will say this phone has a great camera, but half of my photos and VIDEOS are out of focus, yeah, even videos. I tried using other camera apps, same ****ty sound. I don't know what's the problem on this.
[Device Reviews and Information] popo72:
I do not have any audio quality recording issue for both video and recorder app....audio is stereo 48khz with no problems at all.....

About who says that 4h of display is mediocre performance ....well....I have different interpretation of "mediocre" word ;)
[Device Reviews and Information] fishku:
Hi BB72, I saw your post on the other forum, but let me answer directly here since we have more comments on the topic of audio quality here. You advised me to check with the app "AndroVid" what quality my video recordings are. Indeed, they are *saved* at 48kHz sampling rate in stereo, at 127 kbps. But, they are surely not *recorded* at this bitrate and later converted! I can tell that these recordings are way below the expected output of 127 kbps. They sound more like some of the old dial-up compatible internet radio stations which had bitrates below 10 kbps.

Have you tried the method I have explained above, using "raw audio input" with the app "Hi-Q MP3 Rec"? Do you hear a difference between the two? If no, what version of the ROM are you using exactly? Could you upload a sample video somewhere (youtube)?

If you like, I can upload a sample of the regular audio quality vs. raw quality.
[Device Reviews and Information] popo72:
Well I can trust raw is better, but I do not agree (at least on my device) that audio recording is bad....
[Device Reviews and Information] fishku:
Since "bad audio", "good audio", "fine audio" etc. are very subjective matters, is it possible for you to upload a sample video? Maybe what sounds to you as "good" is "bad" for us.

Anyway, I will try updating my ROM soon, but I doubt it will change a lot.

S7yler, do your dialer show the contacts names in the call log? Mine only show the numbers, even tough i got those numbers saved.

[Device Reviews and Information] sansanc:
Allright, then something is wrong here....

S7yler, have you tested the GPS on the road? Here, accuracy goes very high (in a bad way). 30-40 meters. My THL 5000, shows 2-4 meters...
[Device Reviews and Information] s7yler:
with Google Navi? did you also try with Mapfactor Navigation or Sygic GPS Navigation
[Device Reviews and Information] sansanc:
I tested with GPS test. I tested with other GPS app too. Same bad accuracy. YGPS from Engineer menu, also reports accuracy (small letters tough, dangerous when driving).
[Device Reviews and Information] s7yler:
I just tested it with my LeTV S1, while driving GPS Test shows from 8-28, depend on the speed. (when stopped for red, I was on 4-5) Never got anything over 30.
[Device Reviews and Information] sansanc:
Well 28 meters is quite a bit, specially when my THL crap phone never reports higher than 5 meters. At 70km/h LeTV reports 30m, at 80km/h reports 35-40m. Today, i'll test at higher speeds and check in a map app, if it reports accurately. By checking the app location when passing an exit for example. If it takes much to pass the exit on the app.
[Device Reviews and Information] s7yler:
I don't think 28 is much when you drive in the car moving. 28 meters are completed in seconds when you drive.

You should better test it with a navigation app, like Mapfactor or Google Navigation. The "GPS Test" app was not really made for something moving, but when you stand still somewhere.
[Device Reviews and Information] Dreamangel:
Hello guys, im thinking buying this phone,i was have samsung A5 but unfortunately its stolen. Whats your opinion ? Is it worth buying it? I want a phone for daily use, good camera and to work good out of the box.

Στάλθηκε από το Nexus 7 μου χρησιμοποιώντας Tapatalk
[Device Reviews and Information] sansanc:
28 is a lot when other phones report 2-3 meters. I just tested with MAPS.ME, the app shows a big blue bubble around the arrow, that means the "error" diameter. When the bubble is big, the app don't know if you went for the exit/turn or not. That's enough to cause confusion. However, i didn't test it inside a city, where there are many turns/crossings. From the maps.me site:

S7yler, there's definitely something wrong with it. I compared it with a Samsung S4 and my THL 5000. I was seeing the GPS Test app on the 3. Accuracy on them, never went above 3-4 meters on the samsung and thl. I think having some accuracy error on a highway, it's ok, but i'll have to test inside the city.

Hopefully this is a software bug. I mean, the signal is there, 14+ locked satellites, some with 35+ signal.

Another serious bug, while GPS test was running, i got a call, i could hear the ringtone and see the black zone in the top area (the call shows that way when some app is running), but i couldn't see any letters/image. I even rotated the phone hoping the screen would refresh and show the incoming call, but no change. I couldn't answer it.

The messaging app doesn't rotate, WTF..... It's stuck on portrait mode, so i can't type on landscape mode.

My dialer shows the contact names now, but i had to delete and import all contacts.

I also wonder. Have the same situation but with galaxy note 3 neo. Don't know if it's worth to move to Chinese phone at all?

How is the battery life in this phone? How many hours sot?Any signal issues?any other disadvantage besides the gps?how frequent are the updates?
[Device Reviews and Information] januszzbych:
Hi, everyone how is with the updates ? Did you have any one already ? THX
[Device Reviews and Information] sansanc:
I'm getting around 3:30 - 4h, less if i use the GPS, because the screen really uses a lot of power. But i think the battery can last more if the ROM is optimized.

So far no signal issues. On wifi, on raw performance, tested with iperf, it's slower than my THL 5000,but stuff opens faster, my THL had some problem that some sites and multiplayer games would take a lot longer than this phone. Sometimes it would even timeout. Not on this.

Even tough my operator says there is 4G signal here, i have yet to the 4G signal on the phone, but i have to test more, as soon as i go to a bigger city, where 4G for sure exists. I have tried to uncheck all the frequencies but the 4G ones, on the engineer menu, but it checks them all back again! Odd...

The GPS, is actually good, no loss of signal or jumping like my crappy THL 5000, now the accurary is kind of bad, not that it makes navigaton impossible, no, not that. Navigation if perfectly doable, however it can take a bit to know you have done a turn or exit. If you use MAPS.ME, you can see a big blue bubble around the car. That's the accuracy diameter. The accuracy meter rises accordingly to your speed, at 30km/h it can have 15m error, at 80km/h it has 45m error. I have to test inside a city where there are a lot of turns and crossings. I think on "tight" spots, where you are going slower, it shouldn't be a problem. However on "faster" turns/exits, i can see how it can provoke problems. BTW, BEIDU, isn't here. Some say BEIDU is only active for phones bought in China, but for what i've read on their forums, no BEIDU there either. If they fixed this accuracy error, the GPS would be perfect. Again, the GPS is usuable, not like my THL 5000.

I just got my phone, so i don't know for sure how frequente they are, but i'm guessing once per 3 weeks. S7yler here can say more about that. On their forums, they release a "experience" ROM, i think this is the BETA version. But people are complaining they aren't fixing stuf.

The phone is really great, the problem is the somewhat buggy software. And i think this is commom on Chinese companies, lacking after-sale support or "fixing". It's on times like these, we value, more expensive yet "done by serious companies that back you up" phones.

I think you guys should distinguish between live/natural voice/noise recording and music recording from speakers....maybe the phone cut some frequencies when recording music, but to be honest I do not care since I make videos of my life and not of music....;)

Oh and if I can comment on the audio I recorded...

I have normalized the recorded audio to -5 dB and I have exported them from the source file to a 128 kbps mp3 file.

Stock app:

- Voice is fine when I'm right next to the phone

- Voice is not so good when I'm away

- Music sounds terrible, it has a huge bass boost for some reason...?

- Park noise sounds OK

Raw audio:

- You get more noise present at all times. I guess the stock app does a lot of noise filtering too. Maybe a bit too much?

- Voice sounds more natural and you can get a better sense of space

- Music sounds much more like the output of my speakers.

Exactly, talking is fine, but sound of music sucks. It's not a microphone problem but the software/processing definitely! I which there was a camera app that allowed changing the recording settings like that Hi-Q app! And then, changing the video settings too :)

At 720p the phone should record at 120fps but it does only 30fps. I dont understand why this limitation.
