[Q] Samsung SG4 SGH-1337 Sim restart - Android Q&A, Help & Troubleshooting

Hello so I have been having issues with my sim card. A message pops up asking to restart my phone because no sim card is detected. But I changed my sim card the issue didn't appear as often now it began to appear more often. I read somewhere that certain apps are causing that issue. Is there a way to find out which applications so I can delete them?

[Q] sim card does not lock in place

Hello,
The sim card does not lock in place, when I push it down it
just pops up again. Is it defect or am I doing something wrong?
EDIT: Solved it, had to use a scissor to push it down all the way

[Q] Call history lost when changing sim :S

Hi there, I have a SIM card that supports two phone numbers. All I have to do is go to the Sim Toolkit, select the 2in1 menu and it swaps from mobile #1 and mobile #2. Basically, it forwards call from one number to the other.
My problem is that everything related to calls (timers, counters, history, etc.) is lost when I swap between the 2 lines. Also when I go to see my contacts, every time it says that a new SIM has been detected and if I want to copy the contacts from the SIM to the phone.
Is there a fix about this? The phone is the Alcatel 995.
Thank you in advance.
This phone is Dual SIM or works with one only? Maybe it's SIM problem because is 2 different numbers. Android thinks there is a new SIM on the phone, so this cannot be fixed.
Sent from my DEV main phone, Motorola XT316
No, the phone is not Dual Sim. Its just one sim and with the SIM Toolkit you can change between the two phone numbers. Is there at least some application that keeps its own call history and doesnt read it from the stock android app?
Thanks.

Call log history app that has own database?

Hi there, I am searching for an app that can keep a call log in its own database and not read the one off the phone.
My problem is that I have a 2in1 sim card and whenever I switch from one phone number to the other with the Sim Toolkit, the phone thinks that the sim changed and resets my call log.
Another problem it has (for which I dont really care) is that whenever I enter the Contacts app, it says, new sim detected, copy new contacts to phone? but thats nothing.
Thanks.

Preferred SIM toggle not persistent

Hi,
Having issues with setting preferred SIM on individual contacts? It seems to remember when I set SIM 2 for some time, but then everything just defaults back to SIM 1, regardless of which SIM that contact usually calls in on. All of my contacts are either on Google sync or Exchange sync.
Anyone else? I'm on stock ROM v1.72.
I have the exact same problem. Came here searching for a solution after two weeks ago I put a second SIM into my Z7 mini. Although I select SIM 2 as default communication card and I select the switch in all contacts to card 2 it stucks to card 1 and ignores all the settings. Only disabling card 1 lets me call with the second card.
In my case I have a Z7 mini with stock ROM 1.76
Has anyone found a solution for this?

Yes. Apparently one of the apps for my workplace insisted on synching all contacts every 24h. I fixed it by exporting all contacts to my Google account and the problem disappeared.

Not an option for me Actually I have to set card 1 and card 2 back and forth for every contact until I see that I'm calling with the proper card. Either that or disable one card, call and re-enable it and re-set all card configuration. Not the way it should be but...

Phone Registers on Network but "No SIM detected"

I'm having a weird problem with my OneX+ where I can make and receive calls, send and receive texts, view SIM messages but when I go to the APN menu to add a new one a toast message pops up saying there's no SIM detected. Due to this, I can't turn on my mobile data
I've tried the tape behind the SIM fix and that didn't work (The SIM is being detected anyway).
Thoughts? Software or hardware related? Anything else I can try? I'm on the stock ROM, unrooted.
