SCG02 Network Issue - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

During university, my network signals are absolutely horrible. My phone sips battery like crazy. I barely get 3-4hr screen on time if i am using internet from network. My solution to this is that i force my phone to use 3G but because of that i stop receiving calls and SMS. My friend on the other hand has an S21 and he gets 4G+ whereas i only get 4G with 0-3 bar varying. I don't understand why i am not getting 4G+ when we have the same carrier. Any solutions?

[Q] 3g everythere but at home????

I have a problem with my Tmobile g2 running 2.2, it is all stock no modifications whatsoever other than handcent and fancy widget.
The problem is I can not connect to 3g or hsdpa network when I am at home. By this I mean the cell tower that provides service when I am at home. I have txt and calling capabilites but I have no data whatsoever. I have to manually switch to 2g or edge to check email or use the browser. I have called tmobile and they keep telling me that the problem is with my phone, however when I am 2 or 3 miles from my house and it goes to any other tower on the planet everything works fine.
I have searched the g2 forum here but could find no answers. I apologize in advance if this has been indeed covered or discussed to death and I have just failed to find it.
I did find the *#*#4636#*#* option and when it is on 2g I can run a ping test and it finds the server just fine, but on 3g it always fails to connect. Again this only occurs of course when I am sitting at home!
Thanks to anyone who can shed some light on this or point me in the right direction because leaving it up to tmobile has proven to be fruitless.
It might also be worth mentioning that i replaced the sim card today as well, this too had no effect on this phenomenon.....
My mom's nexus s has the same problem. Only difference is that when i walk out the door i get 3g. Once i walk back in, I get edge...... I think its might be just tmobile frequencies poor ability to pentrate walls.
Sounds like a problem with the 3G network in your area, or just a weak signal there.
I know its not the signal strength, I always have full bars at home Its something to do with the network....

Full bars on 3G or 2G ? If you have full bars on 3G then it sounds like a network problem.
I have the exact same problem, but my building is probably over 100 years old with 300 coats of lead paint on it. It depends on your building. Signals can bounce off of mirrors for example and other materials. The more material the signal has to go through, the more attenuation happens.
I have a similar problem, my G2 can't maintain a consistent connection, I will go from 4 bars of HSPA+ to 4 bars of Edge to nothing (lost connection to network) and it will jump around wildly between these three states (every few minutes). My wife's MyTouch 4G doesn't do this, my G1 did not do this, our kids (dumb) phones have consistent connections.
I know it's some interaction between my phone and the TMO network, I'd say it was a defective phone except the only place it happens is inside my house.
I wish that TMO offered a microcell.
There is no reception problem, I have had the phone working here for awhile and it always has full bars, like I said I can hop in the car and drive a couple miles and it works just fine. Tmobile finally got back to me today and said they are having their Engineers troubleshoot the tower that provides service when I am home. I hope they get this fixed soon, they said 72 hours.......
It's that anti-cellphonereception chemical they put into paint!!

[Q] Very poor signal

in my room my signal is always gprs or edge, i rarely do get either 3g or hspa, outside of my house, i get 3g and sometimes hspa, but i get only 2 bar of signal, it's really annoying, i don't know is it my phone or my carrier, but i think its my phone
in addition, sometimes my phone can't get an internet connection for no reason, im have an internet data but my phone just won't connect, the signal bar color changes into white
Carrier?
Data plan?
The right apn settings?
Do you have another phone to test?
Can't just point fingers on the phone or your carrier without concrete evidence.
Check the signal using any other phone in the same places to confirm if it is only your GNex suffering this poor signal or every phone around. Maybe the coverage of the 3G Tower is already poor in your place.
If you really confirm that it is your phone after trying what I suggested above, then it worths to mention the radio baseband you are using. You may also like to check this thread for a list of radio basebands
Regarding the white (or is it "grey"?) internet signal, this is related to whether you are connected to Google servers or not as far as I know. If connected then it is blue, otherwise, it is the other color.
Update: Oh guys you were faster than me although I started replying while no one did already

[Q] LTE/Wifi reception worse?

I'm coming from a HTC Droid DNA, and I've noticed since getting the phone that the 4G and Wifi data connections seem to hiccup when waking the phone. I can't always reproduce it, but I've had the 4G/LTE icon shows up with up/download icons active yet apps hang up on their connections and even speedtest shows poor speeds. It seems as though it sometimes gets better if the phone has been awake/screen on, but that could just be my perception. Overall, it seems that I had better 4G/LTE and Wifi connections with my old phone.
Anyone else have thoughts on poor speeds/reception with their Note 4? Thanks,

LTE and 4G (ATT H810) issues

Anyone else on the ATT G4 having problems with LTE connectivity? In areas where I'd usually get 5 bars of LTE service, a majority of the time I get 2 or 3 bars of Edge service. Putting it into airplane mode and back out doesn't help, turning mobile data on and off doesn't help, and neither does removing the SIM card (and reseting the phone in the process). It seems to come and go whenever it wants to.

All I can guess is, it's probably just the ATT network itself. They did some upgrades around here a while once Cspire started hyping their fiber optic network and I noticed on my older phone that in areas where I used to get 3G I was stuck getting edge. Even with my G4 I can park in perfect view of a known ATT tower and it'll hit 4G and within a minute be down to 3G - same with strength. Get 5 bars, don't move, no data, no call, and it'll drop down to no bars but still connected and bounce around, usually settling at 2 or 3. Even though ATT says they have full LTE out here I rarely actually see the LTE logo display in the status bar.
I've been using OpenSignal to try to map out coverage areas though, been pretty handy in finding towers and chasing stronger signal
Hi sir
I m using lg g4 h810 AT&T it was working well one day i put a memory card in it signal disappear never came go to software and hardware experts but nobody has solved my problem all other functions of cell phone working properly

Wifi calling issue

My wife and I both have a sprint / now tmobile s20 with the same issue. At home I have poor cell signal, 1-2 bars. When I'm on a call using WiFi calling, as soon as I get 2 bars of signal it switch's to volte, and almost always drops the call. The only "fix" I've found is switching the network mode to 2g only, then it will always use wifi calling. Sprint has been no help, and they no longer offer a signal booster. Anyone have any ideas what I can do to stop dropping calls at home?

Since both you and your wife are experiencing the same problem it's likely you're in a dead zone where a decent signal isn't possible due to poor network capabilities. I doubt it's a defect in your devices and T-mobile isn't going to invest in additional equipment for a handful of customers. Your best and realistically only option is switching service providers. If you entered into a fixed term agreement you can terminate it for cause however if your devices are included in a promotion you may have to return them to cancel the agreement. If T-mobile refuses contact your local BBB, that will get their attention.
