No Service but 4G works - Galaxy S 5 Q&A, Help & Troubleshooting

I live in Pakistan and have an S5 G900F, I've been using 4G LTE on it for a few months now.
For the past 2 weeks I've been in the UAE, I switched out my local Pakistani SIM card, and put in a local UAE SIM card and was using 4G over there as well. It worked perfectly fine.
Last night, I got back to Pakistan and put my local Pakistani SIM back in and instantly the 4G data started working, however I was unable to Make/Receive Calls or Texts.
My phone is on LTE/WCDMA/GSM (Auto) mode so when I send a text, or call someone it automatically switches to EDGE (2G), because we don't have VoLTE in Pakistan.
However, when I send a text or try to call someone now, I can't. It stays on 4G, the signal bars disappear and it shows a Cross Icon next to the 4G one. Only data works but I can't call or text.
I was running CM12 all this time and the problem was with that.
I flashed Stock 4.4.2 this morning and it started working normally for about 10 minutes, until the same problem started again.
How do I fix it?
cache wipes and countless factory resets aren't helping. What do I do?
Here's a few screenshots for you guys:

I looked it up, other people on XDA also had this problem but no solution. However if there is one now, please let me know.
Thanks.

I returned the phone, however I lost some money on it.

[Q] WTF SO MAD. Physically cannot insert Sim card into my P8600 that I got TODAY.

I've taken it in and out a few times without any issues. I've been rooting etc. today so i decided that ill keep the sim in my phone while i get things situated. So, I get things situated, and apparently I've broken it. I don't think its my fault at all... the Sim card just simply will not click into the device. I'm pretty sure its because the mechanism is in "SD Card Inserted" mode, but i have NO IDEA how to fix this. I might just send this back and not get a tablet.
Can anyone help me out/give advice.
edit: NOTE: Yes, I have checked to see if im inserting in the correct orientation. I even checked verizons website for a photo simulation.
The pins on the 7.7 are EXTREMELY sensitive. The same thing happened to mine. I ended up setting up an RMA however I just got an email today from Negri telling me that the unit is considered "damaged" and they will not honor the RMA.
I believe this is a design flaw as there is no reason that normal use with a SIM card should cause this sort of damage.
Has this happened to anyone else? We need to make sure that Samsung is aware of the issue.
I believe majority of us here would recommend you taking it to Samsung for repair. While you might have to part with your beloved device for couple weeks but this is possibly the best option.
If you were planning to send it back for repair, I also recommend you to have them calibrating the electronic compass as well if you found it display incorrect reading like mine, which has almost 90-degree off-course.
Happen to me once, push the sim card with something sharp.
hi !

Hi, this happened to me last week. I wondered what the hell was going on. The sim would phisically not push down where it once clicked in place.
I only got mine in January. Luckily I got mine from Panamoz with the £12 replacement warranty. Sent it back to Panamoz last week and they agreed it was faulty and sent me a brand new one which I received today

[Q] Wifi & Blutooth issues

Took delivery of my S4 I9505 in May very happy no issues & had not yet decided whether to root or not .......... I was prompted for an Android update approx 2 weeks ago which i completed with no issues then Yesterday My wifi nor my bluetoooth will activate ...... on the pull down the icons go green but appear 'greyed out' & starting from the settings connection menu has no effect either
After telephoning EE UK tech support was advised remove battery then restart .... no change ....... factory reset ..... no change take too nearest shop for a 2/3 week repair service with a dalek for a lend phone .....
Since then I have tried a hard reset several times ,,,,, I have also flashed the 2 stock roms available through here via Odin with still no change ..... I do not wish to try any rooted roms (I got done with a£120 bill for my s2 from samsung last year ) any other suggestions before I have to succumb to EEs yet to be proven repair service ........
I've got the exact same issue. I've had mine since launch day and no problems at all until two days ago this randomly started happening...

Notice how the buttons are dark green rather than bright green to indicate "on" or grey to indicate "off".
When you go into Wi-Fi settings this is all you ever see...
I read somewhere that this is due to early models having an issue with the wifi/bluetooth chip or the board itself. Unless someone has an idea what is really causing this, I'm going to have to send this back tomorrow which will be a pain in the backside.
Thanks in advance
[UPDATE] Both Wi-Fi and Bluetooth appear to have come back on after ten minutes of constant restarting of the handset. Left the handset on for at least 6 hours, restarted again and then I was back to square one again as they were struggling to switch on. Got it up and running again for the time being though.

Strange mobile signal connectivity..glitch?

I'm not sure if this is a glitch or not. I "think" my signal is fine. WiFi always shows
on, even if I'm not home. I always have a wifi turned on though, just don't always have a signal obviously. My mobile network signal has gaps in it where I would assume it always be green or tan or whatever. My phone seems fine, unless of course ppl are calling me and I'm not realizing it. Any ideas. Here is a pic.

Nobody?
Unplugged my phone an hour ago, have been using it on wifi the whole time, but WTF at mobile signal ??

....?
Looks like signal drop outs for X periods, or the device is trying to search for it.

Wouldn't those times show up in red? It's almost like airplane mode in and out, without effecting wifi. I'm wondering if it is not a glitch though. Bc time on for cell stand by is the SAME as time on battery. And time without a signal is 0%. Would that not mean that is a glitch then in the green bar. Also, before this started I would get green and yellow/gray bars in the status thing. Now it's green or nothing.
Signal drop out don't show up in red for me, - but it would seem a weird anomaly for sure.
Hmmm...I think it's fair to say this must be a VERY rare issue.
Not exactly the same issue, but similar sort of thing. Shows as no signal in known good areas, or shows as having signal but often won't send or receive txts or calls. Oddly enough, when signal cannot be found the data will often still work.
The phone is branded to my carrier so there should be no provider issues. Sim card has been swapped, factory resets done and even had the handset exchanged for another S5 - still no change. It's pretty frustrating to not know if you can use your phone as a phone.
Is anyone else having this issue or is it time to go back to my N4?

[Q] Galaxy S4 connection problem

Hello,
i have an unlocked Samsung galaxy S4 and I keep getting a no service stop sign (see screenshots) at the top of my device. I cannot make calls nor receive any sms messages. However I can connect and use a 4G network.
Things I tried to solve this:
Use other simcards
Switch network operator
Factory reset
Flash Cyanogenmod
airplane mode on off/restart phone
Send my device to samsung for a repair
None of these things helped me out and I really am stuck here, none of my friends who also have a galaxy S4 and are on the same network have these problems and even the Samsung technicians didn't solve it. please see the screenshots below with my network status.

Is there anything else i can do to solve this?
Thanks in advance!
Did the Samsung techs explain what they did? I'm assuming they restored the device to stock and weren't able to resolve this. Since you've done virtually everything software related and the problem hasn't been resolved, you need to look at the hardware.
Yes, I was thinking that too... But what hardware problem could this be? The antenna? Are there any guides on what I should do/check?
There aren't any guides I'm aware of. The two easiest fixes on the S4 are the antenna wire and the SIM card tray. I'm more inclined to believe your SIM card tray is the culprit here, as you are getting 4G signals that you wouldn't get if your antenna was bad. You have tried different SIM cards and had the same result, so we can rule out the SIM itself as the problem. I'd replace the SIM card tray. Replacements are inexpensive at about $10USD off Amazon and replacing the tray is about the easiest thing one can do on the S4.
When you do the replacement, the new tray likely will not have the rubber pad on top of the motherboard connector that the original has. Simply peel the rubber pad off the old tray and put it on top of the new tray's connector. This ensures the connector doesn't loosen during use.

Mobile Data/Network/Internet Issue

I did not have this issue before change my charging socket.

Issiue:
My phone gets H/H+/3G mobile data so hardly.
Even if I inside a building it only gets "Edge" signal or non!
In a building with same phone and gsm op. others get 3G etc. but mine phone gets Edge.
I set APN, wipe cache, reboot etc.. Nothing changed.
PS: If I change WCDMA/GSM(auto) to Just WCDMA, I get H+,3G sometimes in a building but it turns to no service or no data at frequent intervals. Not stable to use..
Reads like you have damaged a component .

Which component you think?
I have seen reports where people used a cheap third-party USB replacement and the phone started to suffer charging, sync, and/or signal issues.
If the phone connects at 3g before the part change, install the old part and see what happens.

I don't have the old damaged part.
Otherwise phone connect the 3G but not everywhere. It doesn't connect in a building but connects out of the building or connects very normally at popular squares.
Is the signal worse with the new part? If it is, maybe buy another one and try? I got cheap one from Aliexpress and it worked very well for a Note 3 n900w8.

Signal is the same like first time no problem.
Simply it doesn't connect 3G or H/H+ in a building connect EDGE.
I guess the only way to know for sure would be to buy another replacement.
Anyone thinkin something else?
Thinking aerial .
