N7100 keeps dropping network - tried multiple carriers. Faulty? - Galaxy Note II Q&A, Help & Troubleshooting

I've had my N7100 for 2 months now and ever since I received it the network will be showing full bars one minute, then completely disconnect the next (the little circle with a stroke through it symbol). It will remain disconnected until I restart the phone, at which point it will reconnect again.
This is an intermittent problem, which occurs on average about 10 time a day. Sometimes it will keep disconnect after only 5 or 10 minutes.
I have tried different sim cards, from different service providers - all have the same problem. When I put the same sim card in a different phone - no problem. So I've definitely isolated the problem to the N7100.
I've tried factory resetting the phone but this hasn't helped.
Is there anything else I should try or does this sound like a fault for which Samsung should send me a replacement device?

Which model are u using? I had the same problem when I just bought the phone.
I realized my phone which is the Lte model was searching for 4g network at times when the reception is poor and toggled to search for 4g network which caused the phone to cut the network because my phone plan only supports 3g.
Maybe try going to mobile network and select WDCMA mode only. See if helps. Otherwise its problem hardware problem

Mine is the N7100 - 3G only (not LTE) model.
Tried that, and it hasn't helped.
Has anyone else been having this kind of problem?

Did you find a solution to this problem. I am experiencing the same issue.

Can't find operator

So I am using non rooted, vanilla htc one v. Installed the updates regularly. I didn't messed with my device bcs. it's my work phone.
Yesterday, I had a plane trip back to my country. While I was in plane, afaik the phone was connected to the operator (local operator of other country). I enabled airplane mode and put it in my pocket, didn't turned it off. I did same thing to my wildfire s also.
So I came back to home from airport, put back my original sim card and now it says it can't connect to network. I choose automatically network search and it says error happened, I tried manual search and it only found one operator (vodafone) not the other 2 operators in my country.
I tried resetting the device with factory data reset. Now it can't find any operators at all, and just says error occured when I try to search networks automatically.
I have no clue about how it happened, it's brand new phone not even a month old. I am wondering what should I say to my company and I also wonder what may be the cause.
Anyone have an idea? or maybe solution to try?
edit: It have some problems with wifi also I guess, it disconnects from wifi frequently and shows signal level too low even though my wildfire s shows full bar for wifi.
Take your phone to service center. That's all I can say. There are network issues with One Series bt I think its been solved.

[Q] ace 2 network problems

Hello
I've just bought a new galaxy ace 2 and I am experiencing some problems.
When I'm using only gsm network type (i think, now I'm testing HDSPA), typically, when I'm logged on icq, mobile sometimes loosses signal and displays there is no service. After few seconds is everything OK and network is back at full singal. This can be seen also in battery usage view, when I'm having always yellow line with thin red places.
I'm now using it with mixed mode on HDSPA and there are no problems with network.
The phone is under warranty, so there is no problem, but I dont have much time and first I would try other solution. I tried to flash it with odin to same fw, but no change. I tried to google it but I didnt find any solution. Could you give me advice?
Thanks for answers
Odp: [Q] ace 2 network problems

Well the "train" issue is due to the train being like a faraday cage, blocking the various microwave signals, the reason you get a signal on a train is because they have amplifiers to retransmit the signal into the train and vice versa.
...what network?

[Q] bad mobile data

I'm having this connection issues where the phone would show the 3g/4g icon but the connection is really slow( slowest speedtest gave me was 0.01mbps). Im testing with a different provider now but is it possible this is a hardware fault?
Same Problem
I have a similar problem, when I enable Mobile Data, it could not connect, I have to turn Airplane mode ON and then OFF and then Mobile date On to get the Mobile Data... Very Irritating... I hope its SW issue
I have slower connection on 3g and h then previous devices
Well its only 4g giving troubles now, is 4g and 3g on one chip or a seperate chip?
Try cleaning cache of your browser
Don't think its browser related because its systemwide. Plus i tries a factory reset already
I've gotten this as well from time to time. Doesn't seem related to whether or not I'm transitioning from Wi-Fi to 4g or not.

I'm getting the same and came on here specifically to see whether it was just me.
These are the symptoms: it seems to happen when I transition from a WiFi network to mobile data network. The data icon still shows activity and good signal but internet access is incredibly slow or non-existent in all apps. Toggling in and out of Aeroplane mode fixes it. I am on a 3G SIM, so for now I have tried to turn of 4G mode and see if this fixes it. Will report back.
This is really annoying - my £100 Acer Liquid Metal did this like 3 years ago... I don't expect a modern £500 phone to have this issue.
I love the phone but issues like this aren't acceptable and I'm getting really frustrated to the extent I might even send it back for refund under not fit for purpose.
Also I have problems with unstable network. Has anyone tried to restore the firmware?

I've turned off 4G as I don't have a 4G SIM, so I'm gonna see if this helps resolve the issue. If not, then I'm going to try and flash a different firmware as my handset came with a EUR firmware and there seems to be some differences between this and the UK firmwares. If that doesn't fix it, I'm going to try the AUS firmware which is a later version.
If I get an success or otherwise I'll post back.
I'm noticing that HTTPS traffic always seems to work fine, but standard non-encrypted traffic doesn't. Anyone else? Seems a bit weird.

Problem with LG G3 858HK.

I have a problem with LG G3 858HK (dual sim).
Sometimes (once/twice a day) phone loses all signal, tries to connect, connects and loses signal again, again connects, loses and so on, and so on. It’s not only data, it loses mobile signal as well. And it happens in all kinds of areas, even where signal is full 4G. Usually nothing helps, except switching the phone off/on again or pulling the battery. Sometimes when switching it off while having this issue, it wouldn’t switch on again pressing power button. Again, opening it up and pulling the battery helps. Sometimes only connecting wifi/ disconnecting wifi helps.
Phone is running rooted android 6.0 (tried few ROMS, rooted/non-rooted - same thing). I tried everything to solve it: factory reset, changing sims, running with one sim, running with 2 sims (its dual sim phone), un-rooting, rooting again, multiple ROM's, tried all kinds of settings - nothing helps. The issue is probably with the phone. Sadly, warranty is expired.
Video of the issue: https://www.youtube.com/watch?v=qq7_jm0-Hp8
The signal in the area where video was captured is really good, full 4G normally.
Anyone got any idea what could be wrong with it?
Any help would be appreciated. Thanks.
Anybody?

It wouldnt be worth using my smart phone for GSM mode only. Then it would be better just to buy some old Nokia 3310 But I'll try.

Network connection drops and squeeze for assistant stops working

Just checking to see if I am the only one having these issues.
I have the 3 XL on ATT, and I randomly have no internet access over mobile data, even though the notification shows LTE and decent signal strength. Screenshots attached to show what I'm talking about. This has happened about 4 or 5 times since I received the phone a few weeks ago. I went to ATT and got a brand new sim, thinking that my old sim may have been going bad, but that did nothing. Only way to get the mobile network connection working again is to reboot the phone.
I have also noticed a few times that the squeeze for google assistant feature will stop working, and I have to reboot the phone to get it working again. Anyone suggestions? I am leaning towards just doing a factory reset this weekend, but I would like to avoid that if possible.
Thanks
dont know about the edge squeeze assisit not working (i use edge sense module and app) but i have to reboot or go into airplane mode to get data to work when i get the x. maybe using a different apn would help... im on att too
AT&T issues
This is now a problem for me. I have to put my phone in airplane and then back to lte at least once a day in order to get mobile data working again. I'm not really sure if it's a network issue or a phone issue.
Issue for me here too, but I'm in Australia on Telstra network.
