hey guys i have a N910c here with a strange problem when i insert a sim the phone detects it but i get no signal at all any possible way to fix this??
Hi, my i9505 has dead power button so i searched on the net and i i bought a not-working i9505 motherboard.
The problem was "sometimes it doesn't connect to the cellular network".
I installed the motherboard, sim was read correctly, insert pin.
All seems fine except it has serious problem registering to the network, and when it does ( maybe 1 or 2 times every 10/15 try ) it can only work in 2g mode, so only edge connection.
When it connectes in EDGE, after a few seconds, it disconnects, i see signal bars change and i understand it's connecting to 3G or 4G. Signal bars comes, but it acts like if it doesn't know how to communicate in that mode.
Using *#00111# i can see LTE freq. which is using.
I already tried unlocking using PERSO SHA256 OFF... unuseful try
Can you help me?
P.S. I forgot to say that IMEI seems fine, efs too.
Hello
I have buy St i959 unlocked
I used it for month with 4.4.2
But when I updated it to lollipop 5.0.1
Signal (cdm)) stopped and back, menu button stop also
I tried to solve this.
The signal when I restart phone appears for 30 seconds
and a message comes saying (refreshing uim card data)
and signal then disappeared.
I tried to inter sim uim setting but I can't because the setting page can't be interred (it say no sim uim card)
What I can do
Restart phone and quickly go to sim setting and sllect network manually
Can't search cdma it automatically
But I sheached GSM in this slot (3 networks avillabe)
as always signal listed
But the page setting still and I choose this time searching cdma networks
In this point the signal comebacks
And I can dial send messages
..
What happens. I will wait days to see
But back, menu buttons don't work
UPDATE:
after restarting phone or use airplane mode
the network lost again
And i must repeat the search as explained above.
Oooooooooooopppp

Hello,
my note 4 - n910G recently started acting weird. It would register to the Vodafone AU, but if i try to call, it would show "Not registered to Network"
Also, sometimes everything works fine for like few minutes. 4g, calls, sms, everything sim related works. and then it would stop working again. it will still be connected to the network, but nothing works. the mobile data sign on status bar shows that Sending is green, but Receiving is nothing when this happens.
EDIT: Sometimes it wouldn't register at all too.
I have tried, factory reset, changed sim, and even done Device Initialization from Smart Switch, because for some reason, ODIN with re-partition pit was not deleting the data in the phone.
Thanks in advance.
UPDATE: so I can use 2g all the time. it's only 4g or 3g which is not stable. 4g network gets registered fast, but doesn't work most of the time. 3g takes way too much time to register, and works a for few minutes before going down.
Is it the network cable or something else? please help.
Same with me when I am in low network coverage area. In the same place same sim card works no problem in another phone.
I did:
1. Restart device and switch on/off airplane mode
2. Change different sim cards
3. Factory reset device
4. Installed root and custom rom (LineageOs). Problem first time occured on stock rom, without root, knox 0x0...
I am not sure, since I am first time using Note 4 in this area, but I think problem might happend sincet latest update...
I was thinking to buy S8 or Note 8 but after this I am not sure...
Some more update:
When 4g sometkmes works, it switches off the phone completely and have to replace the battery to turn on the mobile. Cannot just press the power button to turn on the mobile after it switches of

So, did you fixed this bug?? I have same thing time-time.... ((
The issue is because you have a US Carrier variant of the Note 4, which isn't designed to work on GSM networks.
hi everybody,
My Xiaomi MI A1 32GB lost data connection several times a day. I have only a visual notification - X symbol within signal strength bar(not above like should be in this case). This symbol in general is regarding roaming connectivity, but i am at my home network. When i enter in Settings and deactivate/activate the SIM, the data starts again. All the time i dial and answer the calls, it is only related to data connection in my home network.
Any idea how to fix it in other way, may be to install network signal booster app?
This is an Android 8.0 bug, not a phone one, right?
Regards,
I've had the same issue when using two SIMs. To fix the issue temporarily, I switched to flight mode for a few seconds, then it worked for a while.
Now I've switched of the second SIM card and since then the issue never happened again. So if you don't need two SIMs, I'd suggest to turn one SIM off temporarily till the problem is fixed. Maybe it is already fixed in the February update.
