Constant problems with 3G Internet on my SGS

Hello guys!
My Galaxy S is constantly losing I-Net connection in any of apps which need it. For example sometimes my Tapatalk or Facebook app show "Connection refused". On the next day they are working fine again and few hours or days later the problem appears again... what is causing this in your opinion? Is my Galaxy faulty?
The interesting thing in this case is that the browser is not affected by this problem and works all the time.
It is only in my apps- Tapatalk, Facebook, Translator sometime, Gtalk...

it sounds like just plain reception problem
how many bars do you get when you get those errors?
3G or 2G?

3G and I have in most cases full bars signal...

how about WiFi does it work fine when you are on WiFi or do you also get disconections?

No, on WiFi it is working perfectly!

next time you are on 3G
dial *#0011#
and check what it says on the WCDMA also on the tower CELLID
if it keeps switching a lot, then that's your answer

Only RSCP and ECiO are switching a lot, what does it mean?

Improve WiFi Reception

My GT-I9070P seems to have weak wifi reception. Next to a laptop receiving 5 bars from a hotspot, my phone is only getting one or two bars from the same hotspot. In addition, many other SSIDs that my laptop see my phone does not. Is there any way to improve the wifi reception?

Well , I have no problems here , perhaps your WiFi hardware is defective ?
Might also be a software issue .
I'm the only guy b*tch you'll ever find in XDA.

Your phone receiver is smaller than the one your notebook, so seeing difference in reception isn't a fair comparison because your notebook will always win.
The same about not seeing all ssids.
Nothing much to do about reception, but there are a couple of tweaks for networking posted on the forums.

Mine has issues too. I noticed it improved a little with custom rom JetMod But then I upgraded to JB stock with latest CoCore kernel and its back again to where it started.
I once found a website where it said that of you enter maintenance mode you can adjust the power saving mode of the wifi But when I tried That stock ROM wouldnt let me change the setting. I hope my experience is of any help.

[Q] LTE connection drops every 30 minutes

Hello!
I've been facing some problems with my LTE connection using TIM in Brazil. My 4G LTE speeds are great (about 50/50mbps) and the connection is pretty stable with about 40ms ping. I even use it to play online games in my computer, as it's faster than my home network. But recently after getting random disconnects when playing, I started to take notes of the time the connection was lost, and I found out that it disconnects every 30 min (the 4g icon also disappears and appears back in something about 3s). It didn't use to happen 1 or 2 months ago.
Wanted to know if that's a carrier-sided problem or it's my moto x, and if it's the second option, I also would like to know if there's something to bypass this half an hour limit (I believe it's some connection timeout).
Hope you guys can help me out!

My guess is carrier-side issue. Nothing you can do about it unless they do something on their end. They probably implemented a tcp or udp timeout of 1800 seconds (30 min).
Call and complain...

The problem I am having a similar problem on Verizon. I have to tap the airplane mode to get 4g back. It drains my battery searching for signal.

Sometimes I face this too... Mostly when I get home and it gets stuck in EDGE or HSDPA (I get a poor signal here because the tower is 7 floors above my apartment) and I can't get LTE back... I need to select GSM only or WDCMA only, wait for it to connect to the data network itself and then switch back to LTE. That's weird.
My cellphone wasn't doing this kind of thing before (timeout). I remember playing an entire match of League of Legends w/o further problems. Gonna try calling my carrier this week and see what's going on.

Nexus 6 WiFi issues

Well I've recently started getting issues with the WiFi connection.
I'm sitting a few feet away from my router and should be getting full signals. But what I really get is full signals for a second, then 1 signal, then 2, 1 again, and then the WiFi disconnects and then reconnects.
I'm able to browse the internet fine ( with small breaks when it disconnects and reconnects ) but my phone has started to heat up. I've noticed it only heats up this much when using WiFi.
Any fixes or causes for this problem ?

Your Wi-Fi router is compromised. Do a Google search for chameleon. That's all I can tell you do to NDA.

Ya I agree router issue I had similar problem were I would drop wifi signal at home and had to restart phone to reconnect... Exchanged router and all is well.... AT&T n6 stock

I'll check this out. Thanks.

I agree with others. Definitely a router issue I'd say. No problems for me.

When the phone had root access, you could change the WiFi interval.
I changed it with the build.prop editor. I changed the value of wifi_supplicant_scan_interval from 10 tot 200.

5.0Ghz wifi not showing after pie update.

So I bought note 9 two days ago and it was on Samsung experience 9.5, oreo 8.1. I have a dual band D link router which has both 5.0Ghz and 2.4Ghz wifi. But after pie update the phone is not picking the 5ghz band at all. I have reset the phone clear cache and also changed router settings.
I think its a software problem of one ui. Is any one facing this issue? Anying I can do to get back 5.0Ghz?
Any suggestion will be appreciated.

Not sure what is causing your problem, don't think it's anything to do with Pie update.
I have been using Pie for months and use 5Ghz wi fi without issues.
Also haven't read of others having similar issues on this forum .
Have you tried wi fi analyser app
https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer

Tried with app and still nothing. I have reset the phone, cleared cache and still nothing. Mine is a exynos model and it's update handled by Malaysian samsung team.
After One ui pie I don't even see 4k 60 fps recording in rear camera option. It's an awful update. So many things are missing. They need to work on one ui.

The 4K option is there. Click the 16:9 ratio then click the 1080P option. You're welcome.

Thank You . But I really want the 5.0Ghz band as my speed is super fast. I can download 2 GB in less than a min. 2.4Ghz sucks. I have just reset my router and still not picking 5.0 Ghz up.

Not sure what to tell you. 5.0Ghz works just fine on mine. And I've been on the beta since it was released and now on the official Pie. Never had an issues with it.

Try to change the channel and check.

I have had a similar problem before and since the Pie update. I use 5 ghz band in the same room as my router. 2 Apple devices and my LGV20 are connected to the same 5ghz band. I used wifi analyzer to choose the best channel which for me is channel 40. The other devices hold signal even after sleeping. My Note 9 (unlocked American version) sometimes just loses internet. There is an exclamation point next to the wifi icon. When I check wifi analyzer the signal strength is fine (lower absolute value than 60 or higher value than -60 dbm). The worst thing is once the exclamation point appears (meaning no internet despite retained connection to router) it will never reconnect to internet unless I turn phone wifi off and on. Resetting router has no effect. I reserved an ip for the Note 9 and put the phone on fixed ip so it won't get booted by another device. I'm at my witts end.

If you search the internet you will. Lots of us have wifi icon suddenly show an exclamation point next to it
This means good connection but NO INTERNET! This despite other devices on same 5 ghz network have no problem. Wifi analyzer shows good signal and no competing networks.
The temp fix is wifi off wifi on now it reconnects and everything is fine for 20 minutes or several hours but eventually the exclamation point is back. If it would reconnect or at least try to reconnect it would work but it just sits there waiting for me to do manually.
If we had Bixby routines like the GS10 I would write a routine to toggle wifi when there is no internet but the problem is the wifi IS connected to the router so there is probably no way to write that as a routine... and we don't get routines anyway.
I agree it isn't due to Pie in fact mine is slightly more stable since pie but still that damn exclamation point!

Every time I turn off my snapdragon U.S. version note 9, I have to stand very close to the router for like ten minutes before going upstairs to my room. I have to be standing close to it before it gets picked up by the 5gz wifi. If I do not stand next to it for 10 mins after turning my phone off then on, it will not pick up the 5ghz. I know that sounds simple, but it worked for me.
(I tried first: changing wifi channels, restarting the router, turning off the 2ghz and not the 5ghz, changed passwords for each, I mean everything.)
Hope that helps!

That might help the op who posted months ago and likely solved his problem or returned his phone.
No, as I explained mine always connects and may remain connected for hours or for minutes. It never disconnects. It remains connected to router but stops receiving internet randomly at any time (connected wifi icon with ! next to it
I only use wifi in the same room as the router. It is my mancave and I spend all leisure time at home in that room. I shut off the wifi and the phone before bed. I have unlimited lte data but 5 ghz wifi is way faster. 2.4 ghz is perfectly stable but no faster than LTE+

5ghz AC wifi has always worked for me on any channel, running openwrt on my tplink archer c7 router.
N960F running latest devbase pie rom.

That's good for you but no help to the rest of us. I guess one might deduce my phone is faulty but if so a LOT of Samsung phones have had this flaw for years back to the s7.. I figured if anyone in the world knew the solution he would be in XDA

What roms have you tried?
Why don’t you downgrade to Oreo and see if it works again?

It was the same in Oreo. My phone is stock unlocked Note9 on VZW.
