[Q] Random network unavailability/emergency calls only - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Hi guys so i was looking for answer for this but to no avail. im starting to wonder if i am the only s4 mini (i9190) user with this issue. i happened occasionally even when i was on stock rom. I'm using Resurrection Remix rom now but still the issue persists. it bothers me a lot because people cannot reach me when this happen and i have to fix this either by rebooting or turning the airplane mode on and off. anyone else with this problem?

If you tried different ROMs and are doing the same thing, maybe it the radio module. Return to stock and bring the phone back to Samsung.

Once you get your device and the report could you please let me know what's the cause of the problem. Thanks

Yes, i'll post here again when i get it back.

I also have this problem on my s4 mini(gt i9190) too. And I also don't know how to fix this.But I think it would be IMEI problem, because the IMEI that displayed on my phone did not match the IMEI that label behind bettery.

No sim card error?

Hello all,
Lately I've noticed that my note suddenly gives me this error at random times but usually a couple of hours apart "no sim card" and I loose connection and I have to restart the tablet for it to work. Is anyone experiencing this same problem? Does anyone know how to fix such an issue?

Well I've updated my tab to the 4.2.2 update that's been floating around and that seems to. Have fixed it, or at least I hope so... u should give it a shot if before going with a custom from that's still in alpha phase.
Good luck.

Random sluggish performance that requires reboot?

Hello everyone. I've been experiencing a problem lately that has me scratching my head. The phone for no reason and at random times because super sluggish like the frame rate or something is super low.. It seems to be most apparent in the launcher.. It happens at random even if the phone is cool or hot. Happens on touchwiz launcher as well as nova launcher.. Clearing ram and open apps doesn't work... The only thing that makes the phone go back to normal is a reboot. This also happens on any custom ROM. With stock or custom kernel.. So.is this a CPU hardware problem? Has anyone else had this happen? It's already been happening quite often and its becoming annoying. Factory resets don't solve it either as it comes back randomly. If anyone can shed some light please do.

I would contact T-Mobile it could be a phone problem if you are seing it after an Odin back to stock. That would be my only suggestion is an Odin back but since you already did that I would see about getting the phone switched out

How could I prove to them that this is worthy of a warranty replacement? I can't seem to reproduce the problem.. It just happens..I thought Odin would solve the problem too but then it just randomly happened

Explain to tmobile what's happening and let them know you want a new device. they are very easy to work with and tmobile won't make you prove anything. Ive been with tmobile for ten years now. Trust me they are easy to work with if you explain the situation and let them know it clearly interferes with your ability to use the device as it should be used. You should have ZERO problems with returning the device. By the way sounds like your device DOES have serious problems so id call tmobile as soon as possible. They MIGHT try trouble shooting it FIRST as this is procedure they HAVE to follow simply let them know after trouble shooting that your issue IS STILL PRESENT and they will exchange your device for a new one without issue...so call them asap. You won't have any trouble. You will see. They are very EASY to work with so NO WORRIES. Call and get your device exchanged NOW. Hope this helps you out. I've had a LOT of expirence working with tmobile. It won't be a problem. Youll see. Best wishes to you and hope you get this matter resolved today.

I'll have to agree here. I've had many issues over the years (anyone remember the LG G2X?), and they will stand by you. Sometimes you have to squawk loudly, but they want you to be happy...
Unlike Sprint.....I hate Sprint
Edit: If you're not happy with their response, just escalate it to Customer retention...they have the real power.
I had bad lag when I was trying to text, send an email, or anything involving using the keyboard. I flashed a ROM thinking that would take care of the issue . It didnt, still had hang ups and lag. I flashed back to stock and received a new phone and havent had an issue yet.

I am using H818N , and there is some issue with my camera and cellar.

I just buy a H818N two months ago. But some issue happened , I can't access my camera sometimes. And when it happened I noticed that my network also has some problem. The signal always unstable .
But this is issue happened only few times , but I have completely no idea what it cause.
I just try to flash my device with KDZ but I am not sure if it will work.
Anyone knows anything about it?

[Q] Random restarts

Hi there,
Apologies if this may be a bit of a superficial post but the phone in Q isn't mine so I'm working on second-hand info here. A friend of mine got a G3 off ebay that's t-mobile branded and is supposedly the European model, I haven't checked. (She's using it in the UK nonetheless). Also it has "the latest software updates" (whatever those may be) installed. The phone is not rooted or otherwise tampered with.
Her problem is that occasionally, the phone restarts apparently randomly, though she noted that this happened more when she was in the countryside and the internet connection was coming and going. My guess is that this may have to do with the modem, but not sure. She did some googling and apparently the problem is relatively common but there's no good solution to it.
My two (three) questions are:
- has anyone else encountered this issue?
- any solution to the problem?
- is this a stock firmware issue, ie would installing CMod solve the problem or is this a hardware problem?
Thnx
If it's second-hand phone it's battery issue.
Rushing toward CMod isn't going to solve your problem.
I am also facing the same issue. This also occurs when I'm at my village home. Mostly happens at the same place.
So instead of installing CMod try to change battery because stock Rom is also best and therefore any problem in it means problem in hardware not in software.
But you can still try different techniques. Also tell me if you can solve it.
Installing CM brought no solution for me and still faced random reboots.
i have faced this problem, adter everything i tried then i decided it is battery issue.
i mean change your battery

of course it works now like a rock
I've been having the same issue. My I've used a new battery but my phone acts the same as it did before. Reboots randomly after the wifi, bluetooth, and 3g crash and attempts to recover. The reboot never succeeds and I have to physically pull the battery. Currently using the latest nightly of CM13.
I have had the same issue. I have a stock ROM, fully updated TMobile G3 phone and when i would go to europe, the phone would randomly crash. When it was in airplane mode it would not crash, so i kept it in airplane mode unless i needed to call and i used the wifi calling feature. I thought it was the battery but i have the stock battery and an anker battery and i have never had this problem in the US, it only happened abroad.

Oneplus 5T suddenly lagging

Hi, so i've been using the Oneplus 5T for a year and just recently it started having issues with lag, making the phone unusable. I tried installing different roms without success(Oxygen OS Open Beta 23, Lineage OS 16, and Oxygen OS 5.1.4) and i have no idea what is causing it. This issue began while i was on the OOS beta 23 and it wasn't rooted, it just started behaving that way suddenly i didn't drop it or anything, also the screen blinks and start doing weird things sometimes. Did anyone had this issue? And what can be causing it? Thanks
Link to a video of my problem: https://youtu.be/17LOiftTf8w
Found the issue. Apparently it's caused by google play services, if i clear the data of the app the phone works fine and as soon as i install something from the store it starts lagging again
I always have this issue after finishing a clean setup on oxygen os beta. One restart for me solves and never returns.
same here

What the hell is that lag issue seriously ??
I was thinking to flash a custom kernel and ROM but would it solve the issue ?
And the issue is completely random as well.
I have the exact same issue. Starts when i download something from playstore, open camera after a while or transfer big files e.g transferring data through oneplus switch. I have tried everything i could and didnt help. Upgrades, downgrades, root, trimming storage, clearing cache etc. Nothing is helping. If anyone finds a solution please tell me too. Really frustrated ?
The problem occured on official ROM but it comes back even on Lineage OS 16 (official too).
Do you think it could be a hardware issue ? If not, how come this problem happens even when flashing an other ROM ?

For me it lags all the time, the phone is unusuable. I can reboot, flash a new ROM ... nothing will solve it.
I had this problem for almost 3 weeks and no fix from Oneplus, so I will buy a new phone.

I had the same issue 2 months ago, I tried everything to fix the problem even did hard reset using oneplus' official program and it didn't work.
I came to a conclusion that it's a hardware issue so I sent my phone to repair and one week later I got my phone back fixed.
I recommend you to do the same if you still have warranty, the whole process took only one week. The customer service is really good.

Maybe try to reset your phone by using MsmDownloadTool, if that doesn't fix your problem then it must be a hardware issue.

The problem is that (not only i lost the warranty) but i'm not from the USA and sending them the phone is kind of hard and expensive, to the point that i think buying a new phone is cheaper. I reached to support anyways but i'm still waiting for a response after 3 days. What did they change on your phone?

I don't know what did they replace I didn't get any information about that. The screen is the same though they didn't change it, my guesses are either it's the motherboard or the motherboard to screen connector (it's called main flex I think, you can get on for about 3$)
