[RAZR i Q&A, Help & Troubleshooting] tomrazri:
I've been having a problem with my Razr I which was purchased around the 11th October from Handtec, and I'm just trying to work out whether this was a faulty handset or whether it's common for the device, or affects a certain batch.

The issue is high levels of hiss / interference when a speaker is connected to 3.5mm jack while audio is not playing. Hard to describe the sound as it changes, however it's somewhere between hiss, ground loop and EM interference.

There's also an unpleasant thump when audio output turns on (i.e. just prior to playing audio) or off (a few moments after the audio output is stopped).

The hiss/interference noise reduces significantly immediately before and after playing audio i.e. it seems to go down to an acceptable level once the audio chip is taken out of 'sleep' mode and made active. I can only assume that this is because a noise cancellation circuit is removing the interference once the audio chip is activated, but that while it's inactive the unwanted signal is making its way down the cable connected to the 3.5mm jack.

This happens regardless of whether the device is connected to wall socket - and I've tested with a battery powered speaker - so this isn't a ground loop issue as far as I know. It is most noticeable when connected to an external speaker that's turned up to a decent volume, but is also audible through headphones. Please note that different headphones will show the issue to a different extent, as the impedance of headphones can vary quite widely. Through small earphones, the sound isn't too offensive, but through an external speaker or decent headphones it's completely unacceptable.

I tried temporarily disabling the MusicFX app and doing a factory reset – no luck with either unfortunately.

There is a report on gsmarena from someone who noticed the hiss. They got a replacement and there was no hiss on the replacement handset.

The thing that's confusing me is that this seems like two separate issues - though I may well be wrong.

1) poor EM shielding and/or cancellation circuitry inactive when audio is not playing and

2) no soft-start / soft-stop when capacitor(s) on the audio chip is charged/discharged and/or DC offset on the signal coming from the audio chip.

The phone's in the box ready to be posted back to Handtec, but just wanted to try and understand whether anyone else has experienced this issue? Just to note that although I haven't been through the returns process just yet, support from both Motorola and especially Handtec so far has been great.

that was me. the replacement was much better. still not upto gnex audio via headphones standard but the positives elsewhere on the phone (vs the gnex) mean i can live with the slight drop in audio quality.
[RAZR i Q&A, Help & Troubleshooting] tomrazri:
Ah ok that's promising cheers. As you've mentioned in that thread, it's only really a problem when music's not playing and when the audio chip is activated/deactivated. No realm qualms with the quality of the audio chip itself as i wouldn't expect a studio grade dac in a phone, just the interference / lack of soft-start that was the dealbreaker. Fingers crossed my replacement will be from a different batch :)

my first unit came from clove. my replacement from amazon uk. good luck :)

Sent from my XT890

---------- Post added at 04:43 PM ---------- Previous post was at 04:28 PM ----------

build date on my replacement unit is sep 22 if that helps
[RAZR i Q&A, Help & Troubleshooting] denny76:
I'm having exactly the same problem with my XT890 - bought from Amazon round 10th Oct., device build date is 22 Sept.

In my case the hiss is present only in sleep mode with no music on. I can hear silent thud roughly 3 secs after pressing power button to enter the sleep mode followed by the annoying hiss (only on left ear though). It's not loud at all, in fact it's barely noticeable during the day. It only drives you insane if even subconsciously.

---

I think this is where the problem lies. First I thought its down to frequency response or even impedance. I think its due to different 3.5mm jack layout. I have no problem what so ever on my Klipsch S4A (10-19khz, 18ohm, 4 rings jack) but on my Koss PRO 4AAT (10-25khz, 250ohm, regular 3ring jack) its simply unbearable.

Shall I try to send it back to Amazon in hope the new piece will be flawless?
[RAZR i Q&A, Help & Troubleshooting] alpha beta gaga:
i 'think' i had the same hiss you are talking about on my first device. it was certainly noticeable as i mentioned before and unnacceptable i have no hiss on my replacement unit.

3 secs after any music has come to a stop, it sounds as if the internal amp (?) 'clicks' off. that 'click' is/was present on both devices i had but as that does not interfere with and music playing, i don't see that as a problem.

who knows if we are all talking about the same 'hiss' or not :)

Hiss on Razr I

I had exactly the same problem on first device but on replacement that hiss gone but not all together but 10x better . I have got 64gb micro sd card full of music and I love chillout stuff where any extra noises spoils listening pleasure . Btw my device was prom phones 4 u
[RAZR i Q&A, Help & Troubleshooting] tomrazri:
Replacement received. Hiss/EM interference and the pop still there :crying:
[RAZR i Q&A, Help & Troubleshooting] alpha beta gaga:
ooo that is bad luck. as you got both from handtec, i can only assume they had a faulty batch that moto fixed on newer builds.
[RAZR i Q&A, Help & Troubleshooting] buttgoblin:
Well, you first thought it could be the impedance but you forgot it or what? It's quite common problem that not all the amplifiers like all headphones. Can happen with hifi equipments too, but mostly mobile devices just don't have good enough output for high impedance headphones. Low impedance headphones are a bit more battery friendly.

I think people just looks silly walking around with big-ass-headphones. About the same as using tablets as cameras.

Anyway, my phone does have slight hissing noise with 18 ohm headphones, but I can live with it.
[RAZR i Q&A, Help & Troubleshooting] tomrazri:
Sure I think this is probably not an issue for a lot of people, as I want to be able to output to speakers rather than just listen on earphones.

Agree big headphones look silly, I'd only wear them on long train journey's not strolling around :)

If it doesn't affect the way you use the phone that's fine, and for those people I don't think it should influence their buying decision. The gsmarena review calls out aux audio quality as an issue though and measures it in comparison to other phones, and it doesn't fare so well. It'd be interesting to know whether the situation's improved in later revisions.

If the interference and pop happened with other devices I'd understand it, but I've had no issues with various other mp3 players, smartphones and tablets feeding the same headphones and speaker systems.

Oh well, hopefully be able to buy in a month or so when I'm reassured they've fixed it.
[RAZR i Q&A, Help & Troubleshooting] alpha beta gaga:
i'm confused by what you say above 'not having issues with other smartphones'. i thought this was your first smartphone purchase according to your review on amazon...

[RAZR i Q&A, Help & Troubleshooting] tomrazri:
Yep, phones of friends don't have the same issue. It hasn't been a problem with some models of HTC, iPhone and Samsung that I've tried with the same speaker systems. I imagine there are plenty of older Motorola handsets that don't have the same issue too so it's nothing against them.
[RAZR i Q&A, Help & Troubleshooting] Porkeno:
Posted this question on Motorola customer care, but recived a useless anwser. I don't know phone internals, but my guess is problem lies in incorects volume regullation. Just like with with connection of PC with amplifier, if you would turn your amplifier to maximum volume and try to regulate volume only with PC volume controll, you would get similar noise.

I just want to know can we install apps (.apk format) from recovery menu.

And if yes .how?

Or how to convert the .apk apps to .zip format to install.

Or

Create a zip file
[HTC Pico (Explorer)] #define:
Either create a flashable zip file, or install them through adb... search xda on how to set up adb and fastboot on ur computer if u havent..

If u choose adb, run the following comand to install apks..

"adb install <path to *.apk file>"

ignore the quotes.. run it as many times as u need..

no need to go to recovery for adb.. u jst need usb debugging enabled on ur phone..

and VOILA!!! all ur apps installed widout any hassle..

u can do loads of stuff wid adb.. you can even bypass the pattern/pin lock on ur phone if u knw the right commands.. just an example of the power of adb.. :muscle:

There is an option to create update.zip in titanium backup, do that

Put output to pc, open it from pc( dont extract, just open using winrar) go to data/app

Delete titanium backup apk, drag. Apks from pc in that folder

Copy. Zip to phone and now flash it from recovery, the apps you added will get installed
[Atrix 4G Q&A, Help & Troubleshooting] moeburn:
For some reason, every night when my MB860 is plugged into the charger, the tegra_spi.1 system process goes nuts with CPU usage. With a name like "tegra" I assume it has something to do with the GPU, but a quick google and forum search gave me no answers other than a few people with a Photon having a similar problem, but no one seems to know why. I have no live wallpaper, or any other apps/widgets running that I can think would be using the GPU. Very strange that it only goes nuts when I'm not using the phone.

It isn't terribly important, because it only seems to happen when the phone is charging, so I'm not worried about battery drain. But I am worried about wear and tear; my experience with PCs is that the more you use a component, the shorter its lifespan will be.

Here's a couple screenshots from System Panel:

[Verizon Samsung Galaxy S III] rfranken:
Solved!! see last post

I've been trying to figure this out for sometime now....with no luck.

When...and only when I'm on my works Wifi connection, certain apps won't automatically sync (I can still manually hit refresh and sync them). This goes for gmail, google talk for sure but probably others as well.

My apps all automatically sync just fine when on my Wifi at home, or on 4g, 3g, and 1x.

So what's the deal with my works wifi? (I'm the IT guy here so any changes that might need to be made on the Firewall or Access Point I can make if needed)

We have a 5510 ASA Cisco Firewall and I'm connecting to a Linksys WAP54G access point.

thanks,
[Verizon Samsung Galaxy S III] x714x:
Are you manually refreshing from the apps themselves or from the acct and sync tab in the settings? My dad wasnt getting anything and when i looked he somehow turned off the global sync

Sent from my CleanRom'd Galaxy SIII
[Verizon Samsung Galaxy S III] rfranken:
Either one will make them refresh. But they won't sync automatically. If I turn off wifi at work....within a minute everything syncs up. It's only wifi at the office other wise everything syncs with no issue.

So its not that i have any settings for sync turned off or not check marked. Every other wifi i connect to syncs.....its Only the wifi at the office.

It doesn't matter which Rom I run either. aosp or tw. They are all the same.
[Verizon Samsung Galaxy S III] rfranken:
SOLVED!!

I've been researching this for awhile and finally stumbled upon the answer.

If the problem persists only on WiFi, ensure firewalls aren’t blocking access to ports required for Google Talk and Google Play (TCP and UDP 5228).

I logged into our firewall and opened those two ports and now I'm syncing on wifi as desired.
