[Solved]F5121 Unable to call - Sony Xperia X Questions & Answers

So during the last few days I've been unable to make any phone calls, and I don't understand what's actually wrong. There's nothing wrong with either the microphone nor the speakers, as they work in other apps. The problem is that I don't hear other people and they don't hear me I don't appear to have connection problems either since other apps work as usual, with or without wifi. I'm running the Concept 4.0 rom.
It's possible that it might be some sort of water damage because I dropped it in snow the other day but that seems unlikely.
So far I've tried:
-wiping and re-installing the rom
-wiping and installing the Poison rom
-formatting and re-installing
-tried installing without fast dormancy
-restoring back to old backups, where there was no problem, using TWRP
-I tried my SIM-card on an older smartphone and there was no problem.
So does it seem like some sort of hardware failure or some software bug?
Edit: As of now, the phone works however, I've yet to discover why it didn't work in the first place. If you know anything I'm still interested.
Edit 2: So it's been nearly a month since I posted and I'm writing this because I want other people who might have the same problem to be able to fix it. The problem with alot of the roms for the F5121 is that they lack options for controlling exactly which networks to operate on. The fix for this is to enter the "hidden" menus by entering *#*#4636#*#* in the dialer, from there you can fine tune alot of the settings.

On Mobile network settings > Prefered network type.
If you force LTE only and go to a location with no LTE, you won't be able to call also people won't be able to call you.

[Q] Market and Youtube problem

Hi Friends,
Few days a go as I was watching youtube videos for around 45 minutes continuously through the youtube app. The streaming suddenly paused and never continued from that point. I tried other videos but it kept on buffering (the circle kept on spining and nothing happened, as noticed on the leds of wifi router it seemed youtube app is not using the net but when i search for more videos the thumbnail do showup normally).
To over come this issue i tried reflashing. This happened when i was on the new HyperDroid_v4.0 with Pongster's MattedBlack v4.0 Surgeons which is amazing for battery saving.
I then tried reflashing HyperDroid_v4.0 again after formatting /cache /system /data /sdcard /emmc which wiped everything, but still no avail.
Then i again tried reflashing DarkyROM2 XXKH3 BASE (2.3.4) formatting everything but still no luck at all.
I even tried these flashing after Factory data reset selecting Format USB storage as well .
When i do the flashing everything else seems to be working fine as usual except the youtube playback and android market doesn't download, like i said for the youtube app, everything like searching the apps, browsing through apps details works fine except it doesn't download at all. It shows as if it's downloading but it stays as is forever.
Very sorry if same question was posted before this as i couldn't find like it.
I have been trying to fix this for 2 days in a row but still no luck.
Has anyone come across this same issue.
Please help.
Thank you very much in advance..
Update:The problem was finally solved after again formatting /cache /system /data /sdcard /emmc and flashed stock ROM though Odin and then I installed DarkyROM tool and then flashed DarkyROM2_KI3_Base ROM.
I will soon jump to HyperDroid_v4.0 with Pongster's MattedBlack v4.0 Surgeons again as it has superb battery life.
I will be updating you guys if the same problem persist.
Thank you all
Hello everyone!
Although I am not using GS2 (I have a Galaxy Note), I chose to post here because I didn't want to create a new post and I believe this is not a device-specific issue (see below for why).
I have the exact same problem as OP (as far as I can see). When I got my note less than a week ago, everything was working great. Then, last Friday I noticed that I cannot download anything from the market. After choosing to download something (both paid or free), after clicking "accept & download" at the permission screen, the screen goes back to app screen and market shows the app as "downloading..." with working, yet empty, progress bar. Everything else using the internet works fine - browsing from different browsers, notifications, email etc. I even tried installing an alternative market app, and it would download/install apps no problem. Also, downloading straight .apk files works as well. Later that evening I also noticed youtube app doesn't work - just the "loading" circle keeps running, until it times out. Browsing/searching market/youtube works without a problem. I am using the stock ROM and it isn't even rooted. Later, following some suggestions from google searches on the problem, it turns out that downloads work when I disable network and let it use mobile internet. I also later found out that it works on other wifi networks, just not my home wifi (which used to work perfectly, with no configuration changes to the router).
Next day I also found out that my girlfriend's android (LG Optimus Me P350) has the same exact problem, therefor it is not a phone model specific problem.
Here is what I tried so far:
Factory reset - left me with no apps and no way to re-download them. The market download did work ONCE after the reset, but that was to download the update to the market itself, nothing else;
Clearing Download Manager data - worked for ONE download. At first it worked for one download every time, meaning, after clearing download manager data, I was able to download one app, after that it would go back to the problem. I could then clear data again, and it would again download one app. After about 5 apps downloaded this way, this solution won't work at all anymore;
Force closing/clearing data of market, gmail, talk (in combination with above step) - didn't work;
Signing out/in to gmail and/or talk - didn't work;
Changing google account in market - didn't work;
Stopping/starting download countless times - didn't work;
Switching wifi on/off - only starts downloading briefly when phone switches to 3G while wifi is off. As soon as it gets wifi connection back, the download stalls at the position it was until I switch wifi off again (so it can continue to use 3G);
Switching phone to airplane mode, off/on, then disabling airplane mode - didn't work;
Changing phone's DNS records with an app to OpenDNS - didn't work;
Updating router firmware - didn't work;
Resetting router firmware - didn't work;
Setting port triggering on router for port 5228 - didn't work;
Port forwarding to Note IP for same port - didn't work;
Disabling router firewall - didn't work;
My router is Linksys E1000.
I think that is all I tried. I have been trying to find a solution for the whole weekend, and nothing as far. Searching google makes me believe that many people have had the same problem. I have found many solutions, which don't work, or only work once. This problem is really, really irritating. Also, I have found out that for many people the problem seems to randomly disappear without doing anything after some time (days to months), sometimes coming back and sometimes not. I experienced this myself when after going to sleep, I was able to download one app in the morning with no tried "fixes" at that time. This also makes me believe that there are many "fake" solutions, which did work for some people, but not for others - quite possibly, while these people were "solving" the problem, it actually solved itself, yet because the person did something, he/she believes that was the solution. A notable example of this could be "google account 24-hour reset" where users experiencing the problem are suggested to log out of their google accounts everywhere and not use the account for anything for 24 hours. Seeing as this is possibly a problem somehow connected to another device, not just the phone itself, I did consider flashing DD-WRT on my router, but I wouldn't really want do do that since my router is not that powerful and with all the DD-WRT features my broadband speed gets capped at about 65Mbit/s. Still a lot, but I have a great internet connection and am able to get real speeds of about 90Mbit/s with stock router firmware.
If anyone has any ideas, please share Thank you in advance!
Just a quick reply - I contacted my apartment building network tech, and he said that they didn't do anything regarding the internet that day, but they did however do something to offer TV service to residents (edit: The TV network shares the same hardware as internet's). He said that it shouldn't have changed anything regarding internet, but he would look into it. A few hours later everything is working.
Of course, it could be one of those cases where the problem disappears with no apparent reason, but I guess they did something to fix it. So, if you are experiencing the same problem (market downloads not working and youtube app not playing videos), and you have tried everything else (preferably confirmed the problem persists on someone elses phone), I would suggest you start going up the chain to whoever is managing your network (after yourself). If at all possible, try getting wifi access through someone else who is using the same ISP/network - if the problem persists even when connected to another AP/Router, it's pretty sure the ISP or network is to blame.
Hope this helps someone, since I wasted a few days on this

[Q] Can't get internet to load?

~So I haven't really seen anyone else with this issue so I don't know how to fix it.
My phone likes to randomly not load things via internet. Mostly happens with ATT Data connections, but sometimes it happens with Wifi as well I believe (hasn't happened with wifi in a long time).
I can try and load a page and it will simply not load a thing for a good while (sometimes hours), then all of a sudden it will load like it's on a 10MB connection.
Happens with the internet browser, facebook, and any internet apps. Really gets annoying when I'm trying to browse the internet
I have tried different APNs to no avail, tried turning wifi on/off, changing all wifi settings, etc.
Anyone got any suggestions? (Maybe I'm just retarded and there's a well-known fix for this... at least I can hope right?)
Thanks
EDIT: It also used to never send MMS until I changed APN's if that makes any difference. Just not sure if its a software/setting issue, or if its hardware that needs to be replaced.
There are two APN settings, one of which is used by MMS. It sounds as if your APN settings might have been wrong at one point. What are your APN settings now?
Are you on a different ROM? Do you use a 3rd party app to disable and enable the data connection (to save power)? I know my app sometimes doesn't turn the data back on, so I have to go in and do it myself.
Is this your first phone with AT&T? If so, where did you transfer form? Did you have a data plan with your previous carrier? Did you buy your phone from Amazon?

My APN settings are the "phone" HSPA and "phone" MMS settings from the large thread in this forum.
The phone isn't even rooted. No different ROM, just a stock phone. No 3rd party apps that disable/enable data.

I've had ATT for a decade or so now. Phone bought and activated in an ATT store, and last phone I had was an iPhone, so whatever data plan that used was what I was previously using. I would assume they changed the plan to reflect the android device (if there is any difference), but I wouldn't really know because it is on our family account.
Anybody got any clue? This is really annoying the **** out of me. Also found out my brothers phone (on same family plan) is doing the same thing.

Maybe download Tweakker from the market; it automatically rewrites APN settings for your phone and carrier. CM7 uses wap.cingular, and I used Tweakker to change it from that. Worked, no probs, loved me long time, yada yada.
Thanks, just downloaded it. We'll see if it makes any difference.
Worked great until just now. Lost internet again. Thanks though.
Any other ideas?
i am on AOKP, not sure if you have the options to do the following in stock but try.
1.do you have the option of deleting APN? delete all...
2. force the phone to look for wireless carriers (takes like 4 minutes).
3. click on At&t to registet on it.
4. reboot and the original apn should be there.
I reset it back to the original APN but I dont expect it to help... I had the problem even before I started messing with the APN. We'll see how it goes though.
Any other suggestions are still welcome.
I have a similar, if not the same problem. I have concluded that it's either a modem/hardware issue or network issue. Every one and a while, I'll have to wait ~20 seconds for the internet. This always happens on AT&T data. Once the connection is made, the green and orange data indicators light up and the page loads just fine. Changing the APN's increases my internet speed by a lot, but does not fix the latency issue.
Someday I'll get around to calling AT&T.

Sounds like the same issue to me.
I keep thinking I should go to the ATT store but I really dont feel like having them do a reset of my phone then send me home without actually fixing anything.
Have you noticed what kind of connection you have? I don't use stock, so I haven't thoroughly tested this there, but I believe I experience the same issue. I'm running CyanogenMod 7, and what I see is that whenever the phone drops to 3G, I don't get data. I can force 2G (Edge), which works, and if I pick up HSPA+, I get data. If I'm in fairly sketchy signal areas (bad parts of buildings, fairly far from towers, etc.), I'll notice it flip-flopping back and forth between 3G and H+, with no data. I've never had an issue with wifi not properly loading anything.
I did try switching back to stock for a couple of hours, and it appeared my issues were more along the lines of what you describe, without actually displaying a flip to 3G when I can't get data...but like I said, I don't use stock on a regular basis.
NINJA EDIT: I'm on my second phone with this issue, after getting a refurb due to a USB port going bad. I've tried flashing multiple modems, and have been able to increase my speed, but have not been able to fix the issue when I drop to 3G.

Im in an area where I constantly get 4G or LTE... I haven't really noticed a correlation between the drops and whether or not its on 4G/LTE. I haven't experienced it on Wifi in a very long time though.
Also, the stock APN seems to magnify the problems greatly. Switched back to the Tweakker APN and it runs much better (although it still happens occasionally)
Had the same issue as you, try my guide here: http://forum.xda-developers.com/showthread.php?t=1576199 it seems to have helped many!
Sent from my AT&T Galaxy S II (I777) Killin' it with Task650's awesome AOKP ROM port!
Thanks but the Tweakker APN seems to have solved the internet issues. Only problem now is that MMS doesn't work with the Tweakker APN. Anyone got any suggestions on that?

Data / Wifi / Bluetooth not working

I have read thru a few threads, but they all vary so I am not sure if this is the same issue so i apologize in advance if there is a thread with an answer somewhere...I certainly hope it is not a hardware issue!!...ugh..
I recently flashed Nottach's ROM to my Atrix 4G (excellent ROM!) and was in the process of loading apps and "fine tuning" it to my style and preference when I noticed that my WiFi, Bluetooh and Data are no longer working. I didnt install anything other than a couple of apps that I have been using (GoLauncher, ADW Locker, etc.) so I am not sure why everything stopped working.
I can still make and receive calls and text messages, but I am unable to connect to WiFi ( it sees WiFi signals but it doesnt get past "Obatining IP Address"). Bluetooh enables and disables right away. And I dont see any activity from the Data icon.
I have tried reflashing the ROM, Factory Reset, Wiping Partition/Dalvik, Resetting Permissions, etc. but none of these seem to have an effect on the issue.
I have seen other posts in various forums where some one mentions similar issues and they talk about flashing the antenna via RSD to get it to work, but links to the antenna ROM all seem to be broken.
Any help in getting this resolved would be GREATLY appreciated!
FYI - My phone is Unlocked and I believe it is still Rooted.
Thanks!
Well.. after playing around with reinstalling the ROM I set the Kernal back to Stock AT&T and everything appears to be working again.
So I think the fact that I was using the Faux 1.3Ghz kernal may have caused the issue, which is odd since everything was working fine for about a day before the problem started happening.
Oh well.. i will play around with different kernals to see if there may be a compatability issue some where.
Hopefully this info helps others.

RS988_10h_little or no mobile internet(data?)_seek advice re: rollback/flash forward

You needn't read this thread. There is nothing of any import here.
I was unable to learn how to delete it, or I would have.
As I mentioned below, I manually updated this phone to Nougat using the LG Bridge program. It complicates matters that I can't remember the exact time-frame for issues. I do remember getting real-time traffic updates using google maps even after I upgraded to Android 7. And I did stream Netflix once while on a 12 hour roadtrip, but I can't remember if that was before or after the road-trip. I have found and tried many APN's for the H2O service. Some are supposedly specifically for the G5, others just for mms or internet. Most recently, I did a factory reset after backing up my personal data and media. Twice now actually. The first time, I ran the backup software soon after resetting and when things hadn't changed, I surmised that maybe I was just importing the problem back onto the phone in my settings or something, so I reset again and this time only chose two of the settings categories near the top of the list since they seemed separate to the navigation programming.
I'm going to reset again now and see if the maps work with a stock setup, then see if I can slowly add things one at a time and continually monitor the data functionality.
If a moderator sees this and can delete this post, I would appreciate it since it doesn't seem like it could be helpful to anyone else the way it is. If I am successful in getting the data working and this thread still remains, I will post the process I had followed to achieve that in an "Issue Solved" heading at the bottom. Everything between the snowflakes (*****) is the older post and edits.

> Bought phone used off swappa running MM 6.?
>Have owned phone for around 8 months
>Volume down button wasn't working, figured I could live with pressing vol up and moving it down manually.
> Thought it would be good idea to upgrade manually to Nougat (10h update) Using LG bridge (about 5 months ago?)
> My carrier is H2Owireless, an AT&T MVNO

> Could make calls, send texts, listen to Pandora or Spotify and use my Maps for commuting to work.
> Couldn't send MMS pic msgs.
> Began to learn about APN's and what the different network settings did.
>Tried many APN's and fotzed around with Global, LTE/CDMA, LTE/GSM/UMTS and the submode settings
>Can get 4G and LTE , often have to switch back to Global setting to send SMS/MMS
> Had H2O set up APN as best they knew and network settings to what they felt would work best
> Can do anything and evrything when Wifi is enabled (that's never been an issue)
> I thought phone had bricked about 2 months ago while on a roadtrip.
> Discovered on forum that I could swap cam plus for chin and power on that way.
> Turned out power button was no longer functional
> Learned about vol up + charger to power on phone (use an app to power off and restart phone)
> took off cam plus so I could have phone in case.
And now, I'm standing at the edge of a very deep rabbit hole with a phone that can't use mobile data for most internet access (spotify works, Pandora never worked very well). I've discovered that the version of Nougat I'm running is problematic (update 10h Brightpoint) and that my forcing the update to Nougat might be largely responsible for these issues.
I see myself having a choice between learning how to flash the phone back to Marshmallow, or learning how to flash it up to update 21c... or live without mobile data for most of the functionality I wanted from the phone...
I seek advice from the the forum for which of these options people think I might best choose. Do I need to acquaint myself with these programs used to flash the ROM? Does it seem to you readers that my problems are symptomatic of those which are best rectified by flashing up? Or rolling back to Marshmallow...
I just want to be able to google something while I'm away from wifi.. to get traffic updates while I'm using the navigation.. to listen to spotify.. maybe even watch something on netflix... (calling, SMS and MMS functionality is a given, but I do still have them for the most part).
I can pick things up if I read tutorials / guides... I've flashed PC BIOS before... I could figure it out if I needed to...
But maybe I just need a new chin or clean it? Maybe I should factory reset? Maybe there's other potential causes I'm unaware of?
Any and all suggestions are welcome. It's late here and I won't be reading any responses until tomorrow at work.
Thanking you very much in advance. --Wayne
Edit: I was about to check LG Bridge to see if there was an update available for nougat.. thought I would get this out there first since I was pretty sure I wouldn't get both done tonight..
3rd edit: I checked for LG update, nothing available. I finally decided to factory reset before getting into flashing. That seemed to fix the google maps issue as it seemed to be working without WiFi enabled (I say 'seemed' because my office is slightly below grade and getting a good signal is tough. If it's not working, the address remains grayed out and the connection just buffers, the address filled in after the reset. Then I decided to move some of the things I had backed up from the SD card but neglected to deselect the settings box. After restoring much of what I had backed up, It seemed more like how it had been before the reset. I noticed a small icon next to the signal type and strength meter at the top which hadn't been there before the reset (a small white square with rounded edges that has a zig-zag line going through it that kind of looks like a jagged "N"). Instead of saying offline, the app says poor connection, so I will test it on my way home.. I am hopeful. It seems promising. If I have to reset again, I will deselect settings and set things up fresh; I think that will help. I am beginning to think this isn't so much about my OS or any hardware failure as it is the H2O at&t mvno being throttled or something similar. Even when I'm getting 4 bars of 4G, the maps loads very slowly.. nothing at all like it does on WiFi.
I'll post a final edit after I try it out on the ride home this evening.

MIUI 11 - suddenly lost ability to use mobile data

Happened today. Was peacefully browsing internet with Chrome using my mobile data when suddenly I lost access to the internet. No messages shown on screen or anything.
Chrome won't load pages, showing the DNS_PROBE_FINISHED_NO_INTERNET error code. All other apps that use the internet immediately show an error saying theres no internet access. Additionally, when I ping a remote address (eg. 8.8.8.8) via terminal, I'm getting spammed with "Destination Port Unreachable" so much that the terminal app hangs and I have to force close it.
I already confirmed it's not a carrier issue, other SIM cards show the same issue on this phone, when all of them works on a different device. I tried changing between 2G/3G/4G, reinstalling my carrier's VPN profile for internet connectivity, staying in airplane mode for about 10 minutes (per carrier's recommendation), also tried restarting the phone and even wiping the cache partition.
WiFi internet works fine, so does the rest of my mobile functionalities (SMS, calling). Any ideas about that one?
There are many reports of this happening. It has something to do with the fragile antenna connector/wire. You'll have to open the back cover and check if the wire integrity and connector is intact.
If you are in warranty, send it straight to service center.
WiFi and Bluetooth are on one chip. So if one works, the other should work too.
Cellular is on separate chip.
Good luck my friend. I hope you can get your phone fixed.

That's strange, I'd think a loose antenna connection would not be picky about only impacting internet connectivity but not phone calls and messaging?
Either way I can have a look at this, never opened the back cover on this phone, I assume it doesn't void warranty?
Okay, since I was only evaluating MIUI 11 (flashed it a few days after release) and there were already a few things that annoyed me with it, I decided to pull the proverbial trigger and switch to something else.
And I'm glad that I did, giving LineageOS 16 a try (build 17.11.19) and mobile data is now working exactly like it used to do Good news, since it doesn't seem to be a hardware issue, but also bad news, since it seems like MIUI 11 has some sort of an internal issue that can permanently (?) break mobile data. Well, I'm not willing to put up with it, hopefully somebody else more skilled than me can discover what could have been wrong
guys, i just lost my data connection. 4G logo is available but no internet. I swap from Sim1 to Sim2 slot also the same. I have tested my simcard with iphone 6 and it is working.
