[Q] Strange vibration issue - Galaxy S 4 Q&A, Help & Troubleshooting

Hi all,
Yesterday i bought my new i9505 Vodafone XXUAMDC. Today i found out that during vibrations there are some strange sound at the top of the phone, like electrostatic discharge. What can it be? It has ever happened to anyone?
Also this only happens with high levels of vibration intensity.
Help me.
Thanks

Iv noticed this too. Has anybody else had this problem ?

Yeah like an ufo in your pants

Galaxy tab Bootup sound problem

Has any body noticed that the bootup sound is very low. I can hardly hear it on stock rom. Is it normal or it is only my problem? And does rooting causes this problem.
Thanks and regards

Hi I currently have Overcome ROM which has a different bootup but when I first got my tab the bootup sounded pretty loud, even after rooting it. btw I have GT-P7510 and not 7500
TBH, I didn't even know there was a bootup sound. :S

Finally I've found a solution for this problem. They have separated. System volume adjuster and the media volume adjuster( they were one thing on gingerbread ). So go to settings / volume and increase the system volume

In call Sound crackling/distortion in receiver

I purchased the Samsung Galaxy S4 GT-I9500.
I'm facing a crackling/distortion during calls.
I got my handset replaced twice. My 2nd and 3rd handset after replacement also face the same issue.
I have given my handset again for replacemnt.
Anyone facing the same issue?
There's a crackling/distortion during calls at max volume.
+1
I have noticed that too. Beyond a certain sound, there is cracking sound. Happens on Airtel Network.
Yup!!!!!!!!
Same here. More audible when you hear the ring back tone. its like some thin film vibrating over the speaker.
btw I am on airtel too
Same here, when having a call I can hear a crackling sound, it's minor but somehow annoying. Right now I'm not worried but I'm thinking about how it might become a bigger problem in the future.

Are you airtel too? My collegue has an s3 on airtel.. high volume has the same effect on it.. on 75-80% of the volume its fine

Best time to test it is while dialing 121 customer support number on full volume

Take it from me, it is normal.. my colleague who has the S4 told me that he does not have this problem. I personally checked it and realised that the problem is actually there.. but only some of us notice it.. keep the volume above 3-4th level and you should it be fine..

There is a new update on galaxy s4 india today. Update it and see if the problem has reduced. I feel it has reduced but it could just be a placebo effect..
Sent from my GT-I9500 using xda app-developers app
i'm using MEA f/w and still have the crackling sound, but it's much better when using "clear sound" setting
Same here.. with clear sound enabled it it greatly reduced.

Fixed on MF3 :good:
Sent from my GT-I9500 using xda app-developers app
I can also confirm that samsung has fixed the problem. I am using MF8.
I don't think this is a software issue, but a hardware one.
I disassembled an S4, I unmounted the earpiece speaker. It comes attached with 2 more sensors.
I made a test call with the back case disassembled so I could press with my finger against the earpiece speaker and the crackling noise dissipated away.
Its like by pressing on it the vibration of the speaker was limited and it sounded pretty normal at max volume.
As a workaround, I inserted a piece of low density foam (found in many packaging boxes) between the earpiece and the front speaker grill and the distortion appeared again, but fainter, after I mounted the back case (speaker assembly) and tightened the screws. Indeed, like others said, its best heard when ring tone is playing when calling someone.
The earpieces is found for $3 on ebay as spare parts, maybe I'll try a new one.
I really hope its not a Samsung design flaw. Check the pics. Thoughts?
I'm pretty upset. I paid a lot of money for this phone, it has a problem and I don't like to send it to service to get it raped by some uncaring hands. I would like to have it changed, I hope its not going to be a difficult process as many things are in my country after you pay the money. How hard was it for you to get it changed?
Has this issue been treated in other threads on the internet?
Little offtopic: the best in call sound experience I had was/is with Blackberry Bold series. They have a clear sound, crisp, no distortion, even with a little bass. Sounds solid. Too bad is that limited.
The problem is with Adapt Sound!, disable it in sound settings [Call Sound] and everything should be fine. Hope this helps:good:

GREEN TINT IN S4 i9500

I am using my s4 from past 20 days but today i noticed whenever i open keyboard to type something a slight green tint occurs on the display it is very visible while using the phone in dark environment with zero brightness and with higher brightness levels its not that clear but still it is there ... i got rid of smearing issue courtesy screen adjuster app but this issue is bothering me .... anyone else having the same issue plz let me know.

Haven't noticed this on my I9505, try using another keyboard
Sent from my GT-I9505 using xda premium
I'm having this issue and it's doing my head in!
Every time I bring up the on screen keyboard the hue changes slightly to greeny tone. Then back again when keyboard goes.
I'm surprised not more people mention it.
The easiest way I found to see it was ten brightness right down, go to a dark room and open play store. Touch on the search bar to bring up recent searches and keyboard, then hit the back button, then touch touch bar again, then the back button. Keep doing this so your toggling keyboard on and off and watch the whole screen shift tone.
I'd love to know if it's an issue across the board or if only a few phones are affected.

I am facing the exact issue bro but i hope it will be a software related issue but i am also worried that may be we have defective handsets because very few people raised voice against this issue so it means that most users are not suffering from this issue.

Is this for the stock keyboard? I'm using SwiftKey though.
Sent from my GT-I9505 using xda premium
I tried with other keyboard and its still there
Sent from my GT-I9500 using xda app-developers app
It's got nothing to do with the keyboard.
If you watch a movie on you tube (black and white is best) put to full screen and wait for slider to dissappear, then tap screen to bring it back. The hue changes to green!
It's whenever the screen has to bring something up like a keyboard, menu, slider etc.
Come on guys please can you test this so we know it's a problem on all handsets like smearing or if it's a hardware fault in a few handsets.

Sent from my GT-I9500 using xda app-developers app
Lol there is no 'auto tinting' option. If you mean adjust screen tone, it makes no difference.

This happens on kernels based on MDN below,
anything above MDM the tint issue is fixed.
On ME2 firmware and I experience the same issue. It feels kinda like a 'flicker'.
I have same keyboard tint problem too and its bugging me. Is it a sw or hw issue? Can it be fixed?

mostly all people have this problem & I was worried too about this. But update your phone. you should get a new update notification by now.! I already updated and it fixes this problem. and the smearing issue as well. And then you can also move your apps to sd!!!!!:victory:
Hi, just got my replacement after having some overheating problems and noticed this problem on the new one. I'm pretty sure is the screen, and not a software problem. Mine looks yellowish/greenish on the bottom. I downloaded Screen Test app and notice the problem. I have some pics showing the color differences along the screen. I'll go for another replacement tomorrow.

Check your brightness settings or check the temperature in developer options.
Maybe your screen is too bright or maybe it's a battery issue?

Crackling sound when vibrating on calls or notifications

My GS4 I9500 had a weird crackling sound when the vibration is set to high in calls or notifications. If I bring it down a step or two the sound stops. I have shaken the phone and don't hear anything lose. I have taken off the cover and the sound still persists. Anyone have this experience. Is this just the case cracking cuz is flexing or is this a bigger issue at hand?

Any ideas about this? Can anyone help?
Sent from my GT-I9500 using xda app-developers app
You may have a defective unit. If you are able to exchange the phone for a brand new one, why not give it a try?
