Hoping you didn't get a fake China S6.

Those are the ones that usually behave like that.

But try Settings > more > Cellular networks > preferred network type.

If this doesn't work it's probably fake.

MarkWayne89:
It also depends on your network and if its support 4G, I know the phone will keep staying on the most performant signal.

You can check if this is true by inserting a sim card from another network and check if it behaves the same.

selflover:
thanks I will try that just that my phone uses a nano sim. but is that how all smg s6 phones are?

Stormyweather:
what is the model number? I'm guessing most branded s6 does that

selflover:
I don't think it's branded or how do I check if it's branded. the model is SM-G920F

Stormyweather:
it's unbranded then. did you see this at the back of the phone or. the settings? Go to settings and check about

selflover:
that's what I did

Stormyweather:
screenshot your about device. When last did you do a software update? What android version are you currently on?

Stormyweather:
do you have any update? I didn't see what I'm looking for. If you do have update, try to update it let's see how it goes. Connect to Wi-Fi and open that software update. Let me know what you see there

selflover:
I guess this is what u were looking for

Stormyweather:
yes, update and it should be better

selflover:
the funniest tin is I can't update it. The option for software update doesn't click whenever I tap it. I wish I can get a solution

Stormyweather:
it doesn't click? That's strange though. You can use Manual update then

selflover:
how do I go about dat

Stormyweather:
it's using Odin. Somewhat complicated but it's nothing you can't handle

selflover:
hello nairalanders,
I was gifted this phone some weeks ago, a Samsung Galaxy s6, but the problem I have with this phone is that it doesn't change to 2g or 3g it's just stuck on 4g, whenever I try to try to change it, the fone restarts and still remains in 4g and it seriously is affecting the battery life. pls does anyone have an idea on what I shud do abt it. thanks

selflover:
thanks

Try using this code *#*#4636#*#* then select either GSM only or WCDMA only under phone information

selflover:
I tried it, it's not working

Abeos:


Make sure it's completely typed out not copy and paste, pls let me know if it works

selflover:

Abeos:


OK it seems the carrier on the phone is not the common ones. You may try this code *#0011#

selflover:
