[Q] GPS Performance (and other questions) - AT&T LG Optimus G

I'm looking to change my current smartphone for the Optimus G, and I'm asking myself some questions:
Is the GPS performance any good?
I use it to keep track of my run and use it as a training tool, is it good and performant for GPS and tracking?
How is the sound when recording video?
I know it won't be as good as real equipement, but if you record a video in a loud environement, will it be any good?
How is the internal speaker?
Is it good enough to play a little bit of music on the go or it sounds like a cheap speaker?
Thanks to anyone!

These are all compared to the GS3 since that was the device I had up to this one, this phone is much snappier the GPS locks quicker and seems very accurate. The internal speaker seems higher quality as well not tinny and seems to have decent over all sound. As for the sound from video I have not tried that yet but my experience with others phones is not very good.

[Q] Phone Upgrade worth it?

Is the Galaxy S II worth upgrading to from a Desire HD? Other than the extra camera and the processor I don't see much of a difference. Help me out cause I'm on the fence.
I wouldn't buy an SGS2 but if it comes with a plan it's a nice upgrade
Yes

as you can see in my signature i come from a desire hd as well. compared with the dhd the sgs2 is superior in almost all things:
WAY better screen (although some people have problems with yellowish tint, dead pixels, ...),
far more processing power,
better cam,
WAY better internal speaker and sound quality (you can use the speaker phone with almost no distortion with high volumes),
nice look and feel (first i feared the "plastic" look, but i got used to it and like it now),
much less weight,
to name only what comes to my mind!
so if you trust me, switch to the SGS2, you won't regret it!

IT's worth it. This device...2GB ROM, 1GB RAM, 1.2Ghz Dual Core which android isn't even completely reeady for yet. The GSII won't be outdated for a long time. Yes, there are the quad cores at year end and about this time next year, but the GSII will still be able to keep up. Don't see more than 1GB RAM in a phone any time soon!
Yes upgrade .

Thank you people for your replies, as I too am seriously considering the upgrade.
I have heard a lot of positive things about the speaker.
The one thing, is music quality through headphones, compared to the DHD. I listen to a lot of music and love the SRS. I use PowerAMP, and understand you can use an equalizer as well.
Your thoughts on music quality through headphones?
Much appreciated

The headphones fit nicer in the ear, because they're the soft rubber (circular-squidgy) style, compared to my old HTC hard earphones with only a thin layer of foam for softness.
However the quality still isn't that good, but then again I am comparing to Bose in-ear headphones which I've gotten used to over the past year.
The quality compared with my iTouch playing a song bought from iTunes, is better. I didn't think it would be but playing Poppiholla - so it's got the bass, treble and a range of different sounds, is better. Of course, the improvement is barely noticeable, but one thing I really do like, is the fact at the top right of the player there's a 5.1 surround sound button. This actually works. I could hear the sound of the song change and it sounded really good. It felt as if it were coming from behind me.
So yes, the quality of sound through ear-phones is damn impressive. I just tested it now. (also if you're playing music, you can tap the home button or unlock the screen and a small widget/console/3 buttons slide in from the top making it easy to skip, rewind/go back or pause the music)

Thank you very much for the reply, I use a pair of Shure SE210's which I am very happy with. It was just that I had heard lots of comments about the speaker but little about the sound quality through a decent pair of head/earphones.
Thanks again

I can say that both are good. I was streaming off my NAS Box this morning. Sound quality from it was really good. I had it below half volume and the speaker was a surprisingly good quality, and I was listening to rock (which if I tried to do the same on my Desire, would be very distorted)
Of course the loud speaker comes down to a fair bit of personal opinion, the fact that is on the back, but it's on the bottom of the back - the slightly thicker bit - which is in contact with the surface you put it on. I think it's the sound bouncing back off the surface that actually creates a good sound. Used it on a wooden table and table cloth and the sound quality was good on both.

Audiophile? Lumia 800?

Hello guys
I'm planning to get a lumia 800. Since I always use the phone as a music player with my westone, I would like to ask whose bought lumia 800:
1. How's the sound quality of lumia?
2. In what extent the improved sound quality with the firmware update? I read the review in GSMArena and shown a disappointing result
English is not my native language, sorry for my bad english.
Many Thanks!
Audio quality
I am very disappointed with the audio quality.
If it was my only phone and I couldn't compare it to anything else I would probably think it's ok but yesterday in bed with my earphones on watching a youtube video I kept getting interference noise and the quality isn't as good as on my iPhone 4S.
Also I have tested both Lumia 800 and iPhone 4S sending audio via bluetooth to my car stereo (Nissan Connect) and the difference is shocking. The iPhone sounds as if the cable was plugged in and the quality is great but the Lumia makes it sounds like your listening to FM in a bad coverage area.
Don't worry about your english, it isn't my first language either.
If you really love your music I would recommend you stay away from the Lumia for now, also because battery doesn't last even a day. heh
Hope I could help.
Lumia really miss an equalizer

I'm a Westone 3 user and the sound on my Lumia is beyond disastrous. I can totally confirm the GSMArena results. This was such a shocker to me when I first plugged my earphones I couldn't believe it.
Some users though report that their sound is fine (although it's difficult to sort out people who test sound on stock headset and such stuff).
I still haven't received the update, so don't know whether it helps or not.
But definitely try to test sound before buying this phone! I mean, here it's not just bad. It's totally ridiculously awful.
Soundwise you should look at three things:
1 call quality with phone earpiece
2 call quality with phone internal speaker
3 audio quality of internal speaker
4 audio quality to external device
5 mic
All have different character and should imo be included in a review. Furthermore audio is very difficult to objectively review as user experience is based on personal opinions.
anyway, my experiences with the Lumia are these:
1) call quality earpiece: normal phone calls in office, phone calls with a lot of background noise, and sound quality while in call are very ok, what you'd expect from Nokia. the volume level is okay too, the lowest setting is not too loud like on most phones.
2) call quality internal: okay, loud enough, not too much treble which is very please on prolonged phonecalls.
3) audio on internal speaker, what do you expect from a 3 mm driver in a very small cabinet. I think it's fine, not harsh, much treble and don't expect any bass.
4) audio to external:
a) tested on hi end phones, sounds very well, includes all frequencies, converters sound a bit flat but i'm sure most users won't notice.
b) bluetooth i had someone verifiy and this seems good quality
5) I had someone else call me with Lumia800 and this is as expected from Nokia
But, I'm a bit worried about "audio quality updates" like in the latest firmware. I'm sure they fiddle with algorithms, noise cancelling, auto volume, and minimal levels. I live with the philosophy that whatever is good, doesn't need to be changed.

That's a great philosophy, but it's obviously not good for all users. Whether an update can fix anything or this is a faulty batch of phones is another question.

Can't believe this. MANY users say the sound is awful and I can confirm it also. It just lacks MUCH low frequencies.
What is your HW version etc. ?
Many users have reported improved sound quality and better bass after update released yesterday.

I'll definetely check this, but I'm almost on my way to cashback.
Thank you all
You guys do help me a lot!
I went to shop with my pair of hf5 and um2 to test the phone's demo (It still didn't release at my place.... sigh........ and the phone had not updated with the latest patch)
That's my experience
- NO BASS
- Other frequencies -> medicore
- Stereo is good, it felt like the music is surrounding you ( Better than my xperia pro )
- There are some noise when completed silent...
To be honest, I quite disappointed with lumia , its music performance (I should rephase it, lol) even cannot compete with 5800 3 years ago!
I miss my i9000 with voodoo sound... it is so hard to have a phone with nice looking , good music performance and not-a-iphone
If the sound quality is the most need of you, how do you like the mobile phone "Meizu" in China?
vassilihk, with the UM2, are you using loudness or eq on other phones if that is available?
i agree the sound quality of phones has decreased. everything is made smaller, faster, and lighter and you can see this in the build quality

I do not use equalizer, what i believe a good music player is simply deliver accurate output, pure frequency response is the best.
Let the earphone do the job, not the equalizer, that's what i believe, lol~

Actucally I live in Hong Kong and Meizu planned to release MX on 1.1.2012
In fact, I do have a bias on china-brand phone for its built quality, goodwill... I did not know how's the foreigners think about Meizu
Ofcoz, I'll have a try on MX if it is good

true... true ..
so while typing this i listen to music using good, very good headphones. clean and crisp sound, bass included. no overkill in the bass but the frequency are definetely there. just don't use tiny in ear drivers to generate booming bass sound...
My in-ear beats headphones that came with my Sensation XL improve the sound output on the Lumia 10 fold. it's al about the headphones.
i have an a lumia 800 since 1 week and i am also pretty disappointed by the sound quality. there is no bass, even with the update :-(
i really like the phone, but this is a no-go because i hear a lot of music. if nokia diesn`t change this, i'll switch to an apple or samsung device.
i think we're running round in circles or that different phone users have different ears. however to the suggestion above of comparin hw rev numbers, noone replied.
Okay, I have finally replaced my unit and got one that has great audio quality. The difference is massive.
It has the same hardware revision number and everything is exactly the same, the IMEI is different by about 700, so they have been built in the same production run most probably. There's no way to tell apart from plugging in your earphones and testing for yourself.
Is there anyway to manually increase some frequency values?
It's frustrating as the Lumia 800 sounds great using my Denons, but the very low frequencies are flat, very flat.
I really hope there will be some fix for this because as a whole i like the device a lot and the music experience is great. That said music to me on the phone is easily on the top 3 features so it needs to work.

Whats your hands-free call quality like?

Hi guys and gals, please tell me, what is the hands-free call quality like on your S2. My one is rather rubbish and am not sure if it's faulty or they're all like that.
Sounds great using it up to my ear though.
My old phone, it was virtually impossible to tell I was using on hands-free, my S2 has very poor sound quality on hands-free, is not a big issue but is it normal?
Also the wired headset qualities not very good. On both my voice sounds like it's being played back after being recorded on a very poor quality bit rate. many thanks
Any thoughts much appreciated
Great quality for calls, very good for music, with my AKG K390 IEMs, my backup phones.
My main IEMs - Sennheiser IE8 - are wasted on the SGS2 for music, the AKGs are great all-rounders for me.
The stock went straight in the trash - they're crap. IMO...

Audio quality tested on 2012 Xperias

Hi Xperia users!
I've been doing some basic research into which of the 2012 Xperias have the best audio quality, as tested on sites such as
http://www.gsmarena.com/sony_xperia_sola-review-766p5.php
The tests that this site does focuses on: Frequency response, Noise level , Dynamic range, THD and IMD Noise and stereo crosstalk.
I've tried pasting results here but it becomes a mess. If you have one of these phones already, you can click on your phone from here: http://www.gsmarena.com/sony-phones-7.php
and click on skip to review of music player to find out how your phone performs. From what I can see, Sony's 2012 phones on the whole, don't compare well. The audio output through the speaker is generally excellent, but through the earphones there is a significant drop in quality across the board. If you look through the results, you can compare a phone with almost anything you like, but I focussed on the Xperia S, Arc and all the Apple iPhones and the latest iPod classic. A key element in performance seems to be not performing well in just one area, but across all of them, which the reviewers from the site claim is what makes Apple products the best in the business.
Any comments? Any notes?
I'm in the market for a newer Xperia, but unfortunately, I'm not sure there is a good iPod replacement in this list. The more mid-range Go beats the S and Sola high end phones. I would love to hear Sony's reasoning for this. Also, one of my 2011 phones, while not expensive, beats all of the 2012 phones according to these tests which I don't understand. Any guidance or perspective? I really appreciate the results of tests like these which overcome human bias and subjectivity with terribly overused words such as 'crisp' and 'clear sound' etc. but on the other hand, I realise that numbers in a test don't indicate audio pleasure...so personal and practical use is relevant. :victory:
Are these results reliable do you think? Anything else to consider?
XS: the DAC (think 'soundcard') is great, the headphones themselves are ****ty. Get something better and you'll have really nice sound.
i am also interested in this. i am planning to but Xperia S in saturday but have my worries about the sound quality. its using the same sound chip with sensation xe and the sensation. i can tell that from the frequency graph of them all. they all have same vibrating between 1K 10K.. but when i look at the dynamic range (the ability of pruducing the most differet notes at the same time) and the noise level (basicly the loudness without losing the clearity) are worse than sensation brothers. we can adjust them easily with software (because the difference is something like %1).
but the most important part is the distortions. i mean you can listen your music with %1-2 less volume but no one would want to listen any distorted sound. sony seems like doing better on the IMD+ values but the most important is Total Harmonic distortion and it is very high on the xperia S. however, by looking at the positive values of the sensation XE i believe this problem can be sorted out with software too..
in real life? with a lossless music or comparison sound file we can feel the difference by listening to both an ipod and sony xperia s with the same earphones. and luckily we can change our sound chip software by flashing new mods. and we also can use cyanogenmod which enchances the sound capabilities of many devices.
so there is no way of measuring what we can do with a fully sound tweaked sony device (maybe we can ask gsmarena to run their regular test on a tweaked sony device) but there is room for development in sound department too for sure
That's a really interesting point about tweaking devices. I'm not totally sure I can rely on it though - my last Xperia phone had great audio tweaks but on my latest Xperia phone, all of the audio mods that I've tried detracted from quality, not added so I uses stock audio options.
Good to see someone else in the market for a new phone on the same line of thought as me. I was almost definitely going to get the Xperia Sola but the audio tests on that site indicate it is WEAK with audio! Other phones like the GO which are not marketed as multimedia devices have much, much better results. I cannot buy the Sola if the audio is that bad.
I was going to ask can there be any compromise on the performance indicated; there were around 5 criteria tested, would you buy a phone that ranked poorly on one of them, two of them?

Do you have the Xperia S?
This is the first thing that i felt when i moved from Lg Optimus Black to Sony Xperia S: a drop in sound quality. I use a Koss Porta Pro in everyday listening.
I think the Xperia S has excellent sound quality. To give you some context, I used to own a Creative Zen Vision:M MP3 player, which sounded better than all the iPods and iPhones I compared it with (up to iPhone 4). I wasn't expecting my Xperia S to replace the Zen, but to my surprise it actually sounded better to my ears. The general frequency response is a bit flatter and it's a lot clearer.
I also compared it with a Cowon Z2 (which many people believe to be the best-sounding MP3 player out there) and there was very little difference. Believe me, the Xperia S is a very good music player indeed. The review on the site you posted said it: "A solid overall performance, which should please anyone but the most demanding audiophiles."
As the review states, the only limitation is a bit of distortion at higher volumes, but we're talking deafening volumes here. There's also a way around it, if you're really serious: a portable headphone amp (I use a cheap but very good Fiio E6), enables you to take the clean lower-volume signal from your phone and amplify it cleanly through your headphones. However, I can assure you it sounds fine without an amplifier.
That is very interesting ^^
I was hoping there might be people who take the holistic view too; looking at the stats but also just listening to what your ears tell you. I'm truly open to these ideas. I was particularly looking at the Sola, but of all the 2012 phones it's stats are the worst. Is that really something to worry about? That info. on the S really changes things...:fingers-crossed:
p.s. I found another site that does these tests. Some of the results differ a little, I guess different testing equipment and earphones. There are 3 very different results for the iPod 6th gen. With that kind of variance, maybe the results for the 2012 Xperias is one snapshot - and not definitive?? For anyone interested,
here's the list of devices tested: (no Xperias unfortunately) http://www.markuskraus.com/RMAA/rmaa complete - html.html
Here is the 6th gen iPod Classic: http://www.markuskraus.com/RMAA/iPodClassicFiiOE1/data.htm
The iPhone 4S: http://www.markuskraus.com/RMAA/iphone4s/data.htm
Also, on this site: http://macintoshhowto.com/itunes/which-ipod-has-the-best-audio-quality.html they keep talking about the audio chip used in devices. They mention that certain iPhones and Galaxies use the Wolfson audio chip, which seems to very highly regarded.

Just get the Sola, then get the Wireless Bluetooth Pro Sony headphones which have the new Wofson decoder which is about the best mobile decoder around. I have done that and it is great. Best of both worlds.

hey,
just trust your ears, don't see bad or good depend on testing etc...
i have xperia s, arc, w995, aino, iPod nano 4
the best sound quality for me is
1.W995 (but lack of FLAC)
2. XS (can play FLAC)
3.Aino
4. Arc
5.iPod. ipod sounds great, but after i used itu 2 years, becomes crap sound (don't know why) maybe bad capacitor?
i used FLAC or WAV in my phone (85%)
Which phone do you have now? FLAC eeh? That must burn up the battery! Do you still have an iPod now too? Which one? The iPod I'm using now is the 6th generation Classic. I'll almost definitely have a new phone next week.

how can one get better once one've had the best? lol.. imo, FLAC is the best audio compression right now the battery drain isnt that much.. but the quality of the audio, is that much .. remember when talking bout audio, it's "garbage in, garbage out.."
and yeah, just trust your ears, and dont forget that synergy made better sound than all that graphs and frequency.. and what i meant in synergy is the hardware (dac, dsp, etc), the software (in sxs: walkman and its sound enhancement ), and of course the output (earphone, headphone, speaker, etc)
i did a quick test in flac-listening in SXS (unknown dac , walkman) and SGS3 (the so called wolfson dac, stock audio player), with Yuin PK3 (imho, a decent earphone), and i found out that SXS did sound better. well, i've seen there are mods for sgs3's audio, but didnt try them, both phone are at default (in terms of audio )

Its many Sony's software and optimizations that make it sound good. Wolfson is the best DAC when tested, while Sony uses a run of the mill snapdragon DAC. Just goes to show Sony knows sound.
FLAC actually doesn't drain more battery because it uses less calculations to decode.

i think we should not consider "compressed" music files like zip or rar files. because they are compressed in an unusable way and needed to be unzipped to become usable again and once they are uncompressed there is no loss in the actual data. so in order to be able to use (listen/watch/execute) a compressed data you need to make lots of procceses through CPU.
however that is not the case in the compressed audio. when compressing a lossless (just recorded the way it was played in real life) audio the codec (or whatever it is that has the alghoritm to compress) listens and analysis the audio and decides which sound to combine. for example; imagine 3 different waves are present at the same time and the alghoritm creates a 4th wave which has the very similar sound of those 3 played at the same time and it records that 4th one only instead of the first 3. and there are some certain signals that give the impression of surrounding when applied to human ear. finally the alghoritm writes these signals on to the "simulated" waves.
so, basically when we listen an mp3 or any other compressed audio we have the impression of hearing everything but actually we hear a replicated sound which is very very much similar to the total amount of the original sounds for the human ear.
since both FLAC and the mp3 formats are both read only and there is no real time compressing and uncompressing every time the, load on the CPU (or the DAC) should be measured by the "waves" or "codes" that needed to be read. according to this we can say there is much more signal to read and convert to analog in FLAC files..

however that is not the case in the compressed audio. when compressing a lossless (just recorded the way it was played in real life) audio the codec (or whatever it is that has the alghoritm to compress) listens and analysis the audio and decides which sound to combine. for example; imagine 3 different waves are present at the same time and the alghoritm creates a 4th wave which has the very similar sound of those 3 played at the same time and it records that 4th one only instead of the first 3. and there are some certain signals that give the impression of surrounding when applied to human ear. finally the alghoritm writes these signals on to the "simulated" waves.
so, basically when we listen an mp3 or any other compressed audio we have the impression of hearing everything but actually we hear a replicated sound which is very very much similar to the total amount of the original sounds for the human ear.
since both FLAC and the mp3 formats are both read only and there is no real time compressing and uncompressing every time the, load on the CPU (or the DAC) should be measured by the "waves" or "codes" that needed to be read. according to this we can say there is much more signal to read and convert to analog in FLAC files..

I know how it works. Yet, due to specifics of the implementation, FLAC is faster to decode in the specific case of Android.
Ok.. after reading this thread, I decided to compare the audio quality of my SXS with my good old Samsung wave (having wolfson DAC), and my cousin's ipod nano. I am no audiophile here, but to my ear the SXS sounds the best with wave & ipod definitely sounding louder (but bit harsher). I used the default music players and philips shp 2700 to compare them. Tbh my eyes (wrt camera output) n ears (wrt sound quality) really don't go along with the gsmarena test results! Thats just my opinion.
BTW, has anyone tested the auido quality through bluetooth? since i ll be using it with my cars bluetooth i wonder if i ll get any problems with the audio quality or the bluetooth itself..

Thanks for sharing your results! I was beginning to wonder which devices everyone has here, we could mention which you think works best for you and run with it.
I've been using and testing music on various Xperias and iPods over the last few years. My nanos beat my classic and yet my 2011 Xperia has clearer sound with less hissing, especially at higher volume.
As I've been exploring on another thread, to get the best out of your Xperia on Android, it seems we need better class SD cards (I'm now looking at only class 10) to overcome the longer 'distance' that the data has to travel (computer, cable, phone, SD vs iPod 'distance' of computer, cable, iPod) and such an SD would boost transfer speed of course. I want to get each piece right; quality of audio on phone, better SD and perhaps cable and better earphones.

GPS performance (and some other questions)

I'm looking to change my current smartphone for the HTC One X+, and I'm asking myself some questions:
Is the GPS performance any good?
I use it to keep track of my run and use it as a training tool, is it good and performant for GPS and tracking?
How is the sound when recording video?
I know it won't be as good as real equipement, but if you record a video in a loud environement, will it be any good?
How is the internal speaker?
Is it good enough to play a little bit of music on the go or it sounds like a cheap speaker?
Thanks to anyone!
