Please help me - Galaxy S II Q&A, Help & Troubleshooting

Dropped my phone and battery fell out turned it back on with a pink screen and I turned if off immediately when it came back on the phone was in plane mode I turned it off. Nothing happened reboot airplane mode again turn it off. No sim but there is a sim, try another sim still no Sim. Now after 20 rebooted there just is a no sim icon and when I try to go into dialer says no network. I flashed another modem to no avail I honestly believe I have broken the internal antenna or ruined something else to disrupt all cellular network.
Note that wifi work's still. I don't have a vast knowledge of the components in the s2 does anyone know if it shares the antenna with another radio like wifi or Bluetooth so I can narrow it ddown.

PS the pink screen went away after reboot. And by pink it wasn't a solid colour it was the normal display with a pink tint

Guys after many reboots and slipping sim in and out a dozen times I've got cellular back. Thanks God

Looks like it´s broken, sorry to say.

Doesn't sound good at all. Even if you can get it to recognize the sim sometimes I think there's a good chance it will lose that again at some point in the future...

Sound distortion (electric surge)

Hey guys
I have a very strange sound distortion (not a regular one). Sometimes at a very random frequent, my phone produce this strange sound distortion its like an electric surge sound. It happens during calls as well as when playing media files. It just block the source sound from media files or voice from calls. Sometimes it goes by it self (it stays for some seconds) and sometimes I have to pull the battery to fix.
Things I noticed,, it happens on stock rom as well as cooked roms. My evo is GSM version bought from UK. I have a feeling that it happens from the network but im not sure
Any help would be appreciated
edit: It happens when I touch the screen, the sound distortion comes if I flip my finger left and right the distortion get stronger until there are no sounds at all.
edit2: It seems turning airplane mode on then off solve the problem for good period of time (phone been working good for more than 10 hours now without this problem occuring again, but I know it will come back :S )
come on guys

You're upset because people didn't respond to you for two hours in the ass hours of the morning?
But seriously, it sounds like poor grounding on a speaker or the touch screen or something. Might want to get a replacement. It'll probably get worse over time.
We have different time.
Anyway I found that turning airplane mode on solve it for a while.
I'm not sure what is it right now :S
Is it touch screen, radio, speaker or even stock kernel.

I would still look at getting it replaced. That could be some bad shielding on the speaker if you're not getting buzzing when the radios are off.

Thanks m8,
It's hardly reproduceable after turning the airplane mode on and off. It's working good from my last reply.
I don't know what to do when I ship it back. As it may not happen without a sim card.

You should be able to exchange it under warranty. Usually they don't require you to send the sim card back, I don't believe.
Second day with no problems after using airplane mode.
I can't return this device if I can't reproduce the problem.

keeping it on airplane mode doesnt solve the problem and besides you can make or recieve text messages or calls? Pretty much rendering the phone useless. take back to store sounds like a hardware problem.

[Q] S3 died in pocket - wont switch on, no download mode/recovery no nothing

This morning my S3 was working fine, fully charged over night and functioned as normal. Sent a text, put it in my pocket and went about my business. Checked the time half an hour or so later... still fine. Came to make a call an hour after that, the screen was off and i couldn't get it to switch back on.
My first thought was that it must not have charged over night, plugged in charger and tried again but still nothing. Luckily the misses has an S3 also so I tried her battery in mine and vice verca... her phone switch on with my battery and was still charged... mine still did nothing at all with her battery in. Absolutly nothing!
I can't get anything out of it... wont switch on, no download mode, no recovery, laptop wont pick it up via usb. Its not like it banged anything whilst in my pocket as i was just sat watching TV and an hour ago it was fine.
Anyone had this or know what to do? Is it worth making a JIG to try and force download mode even though no button combo does anything at all? (believe me i've tried them all!)
Phone is rooted and *was* running a custom ROM with no problems. Does it need a trip to a service center? If it has to go for a warranty repair is there any way they can tell root/ROM if no download mode/ recovery?
I could understand if I f***ed it up when flashing something but as I say I was doing nothing at the time.
Thanx in advance for any info!
Theirs a thread started called "borrow a jig near you" if you cannot access download, recovery or anything I think that's the only option you have or the dreaded service centre lol

Happened to mine. Totally dead, was sitting on desk so wasn't touched between last use.
Sent it to Samsung (Regenersis) who replaced a power management IC and the main board.
Sadly it returned with very poor cell reception so went back, and has since come back still with poor reception, scratches, and lint under the camera glass! Not too happy with Samsung's repair centre atm!

If it returned with more problems, you can ask for a replacement.
You don't think I have already?! Haha
So far my pleas are falling on deaf ears. Spent several hours on the phone to them when it come back, before I got someone who would escalate it further and am waiting for their response
Sent from my Nexus 7 using Tapatalk 2
Cheers for the replies. Looks like it's off to the service center for a fix and some added problems.
Just hope they can't check the flash counter or ill be paying for it!
EDIT: just spoke to my carrier and because its only a few months old they will replace if free of charge!
Anyone know if it will still have all my personal info on it or is it too dead to talk to anyone?

If they replace it, they will send it to the service centre at their expense so it will be wiped anyway

Well funny story really, i ride a motorbike to work and back each day and i have my phone in my jacket pocket as i use it as a mp3 player and listen to music while im riding, basically i was going down a private road at high speed and my music stopped i looked down felt my pockets and swore rather loudly. Turned around and after about 5 mins found the phone and its case, (still missing my sd card and battery,, it was about midnight) went back the following day and found the sd card and battery, unfortunately the screen was smashed and the lcd was also cracked it powered up but there was no picture, i have noticed after further examination that along the bottom of the handset on the back just above the charging port there is a crack in the plastic and a bit is missing and you can see two springed metal connectore, now whether these connect to the antenna for network or not i do not know, ive been googling non stop and the general idea seems to be imei problems??

Mobo could be damaged. Either that or the antenna is missing. The antennas are located on the right and top of the moon. It is exposed when you change the LCD. If you switched it yourself, check those connections. It's pretty easy to check it.
Right and top of the moon? Also the phone works perfectly if not faster than it used to wifi Bluetooth etc all works is the antenna with the wire that runs down the right anything to do with it ?

Exchange/Replaced

Hello,
So my T-Mobile HTC One has two problems.
Firstly, while restarting the two buttons at the bottom will keep flickering for about five minutes before the phone turns on.
Secondly, the phone's 3g connection (while abroad) keeps going on and off. This doesn't happen on any other device. Also, the battery life has really gone down recently.
What are my options for this getting replaced for a new phone and not one of their replacement phones? Last time, I had the HTC Incredible and went through like 6 replacement phones.
Thanks,
Crazysah
First off when you hold the power button the lights will flash and then it will power off.
That's just how the phone works.
The battery life sometimes can take a day or so to adjust. Mines is pretty good.
And on the 3g I wouldn't know since I get 4g or 4g lte 99% of the time and the other time it's just bars and edge data
Sent from my HTC One using xda app-developers app
No no. When turning on the phone, the two capacitive buttons on the button will flicker for a good 3 to 4 minutes before the phone turns on. Never used to happen.
The battery has been going down ever since I started using this phone in May.
3G going in and out only happens abroad, not in the USA.
3g is probably network related if it only happens abroad.

Yeah but doesn't happen on any other phone. So it is definitely a phone problem. What can I do?

I had the Purple tint issue with my first HTC One, and just got my replacement. The camera is definitely way better, no purple tint whatsoever, build quality is better than my first device, no gaps and the power/sleep button is not excessively recessed. But, I do notice the screen of replacement device, the second HTC One, is yellowish compared to my first HTC One. I have been on the fence if I should contact T-mobile, but sorta do not feel the need to go through the process of unlocking, unrooting, s-off, cid, firmware update and running a custom rom.

[SOLVED] - Xperia Z Ultra Poor Signal Reception Indoor

Hello,
I have bought an used xperia ultra off the internet.
The problem is that outdoor I have no issue with my signal. But when I go inside the signal drops and it shows me NO NETWORK.
Is there any solution for this ?
Thank you in advance !
I have tried software update and hard reset with no luck ...
Depends on the type of house you're living in and the general coverage in your area. I live in a concrete apartment and i have excellent coverage, so it might be the coverage in your area? How many lines do you have when you're outside?
Now I am using my sim card in a nexus 4 and i get full signal in the same place where my xperia doesn't.
The cell tower is not very far away ...
So, the house is not a problem ...
P.s : nexus 4 has full signal on wcdma but xperia has no signal/poor signal even on edge/gprs ...
As you can see in the picture, every phone tested with that sim has full signal in the same place. But not the xperia ... I think it's "blessed" ...

Weird. I get better signal than ever with my Z Ultra. Inside on the countryside right now where my signal always was 1-2 bars with most of my other Androids and i often lost the signal temporarily. I'm sitting on full 4 bars now with my Z. Amazing!
Sent from my Z Ultra
Well you are a lucky man, congratulations. My problem is that I bought the phone in a different country and I'm pretty sure that the folks here in my country will deny the warranty ... And going back in the country of purchase is not an option.
Does anyone have a Modem/Baseband that could be flashed to see if the problem still persists?
Thank you !

Problem solved ...
For all of you that experience the same problem, take a hot air gun, heat up the back of the phone, and slowly take it off with a suction cup.
After doing that, check the cable that comes from the antenna to the motherboard. Mine was loose, and I hat to fit it back in it's correct place.
After powering on the phone, the signal is OK !
Attached a photo below:
And a video with disassembly instructions.
Hope that helps you.
Hi there - by antenna, do you mean the whitish cable on the right-most section of your picture?
Another thing, did the back cover stay attached perfectly after you've re-assembled it? I mean using the heat gun on it didn't make it permanently loose?
What about water-proofing?
Thanks!

Same here. Will this solution not affect the waterproof of the phone? Anyone has any other solutions?
Sent from my C6833 using xda app-developers app
Wouldn't it be easier if you just send it in to Sony?
It would be, but I bought it on ebay and I don't have receipt for it. The other thing is I noticed when the phone is in standby it has full signal when i start using it the signal bars are going down.

Hi. Finally it's working and yes the cable was loose. It's really easy to open the phone. It's the cable on right it's grey and silver ( like on picture) You can buy new original adhesive tape on ebay for £5. I don't know about waterproofness after. I will try when I will get new phone. Hopefully ultra2
Sent from my C6833 using xda app-developers app
I'm surprised you'd even want a new one after dealing with that. Hopefully I don't need the original receipt to get warranty service. I hate the idea of opening up a new phone to solve a problem with a home remedy. As you can tell I am suffering from the same issue.
3G and 4G can have poor reception indoors. See if switching to 2G only helps, even if you don't have mobile data enabled.
It was the only way to normally use the phone. It took 5-10 min and now it's working perfect. Try with Sony service centre, I hope they will do it for you. It's best phone ever, I hope they will make ultra 2.

I have exactly the same issue
aaand now I have the same issue. ****ING hell...*****phone ...eh gonna send it in someday next week. I don't have the receipt here so got to go to my other apartment first
a weird solution that worked for me
Hi guys I had the same issue and solved it finally
First I tried your method and checked the antenna cable mine was already in place and fine so I was depressed and closed the phone back.I tried every thing else rebooting,repairing through companion,updating the rom, changing sim, changing network and every thing else. Finally I took phone into service they returned it without the issue and I was pleased too much, but same issue returned after 2 weeks
So I tried a stupid thing that worked like a charm I put 2 pieces of paper under the sim and above the sim metal holder and inserted the sim back then the issue was solved and network is like any other phone finally
It worked for me and I think it may worse a try
Mindgasm
I Just bought my New Z ultra Last month. At beginning i thought that my Z ultra poor signal were normal (90-110 dbm) until I compare to my friend's Z ultra. I realized there's something wrong! I was hopeless till I found this thread. Thanks to Al3xxxinho it worked! The antennA were loose also. Easy to open and I didnt see it Will break the warranty seal if you open, and the back cover still fit perfectly. Now I enjoy full signal bar. :laugh::laugh::laugh:
What I did was chanel the preferred network type to wcdma
