Let's state all the possible letters in the signal indicator, in descending speed (indicated speeds are roughly theoretical maximum): 5G = 20 Gbps LTE+ = 300 Mbps LTE = Long Term Evolution (commonly and falsely known as 4G), 100 Mbps H+ = HSDPA Plus, 10 Mbps H = either HSDPA (3.5G) or HSPA+ (3.95G), depending on your network provider, 2 Mbps 3G = UMTS (3G), ...

I did not find a way to reliably do it without an app. I often use OpenDNS Family Shield, but sometimes it blocks me to visit some particular hacking site and then I need to quickly and easily change the DNS servers. I used to use Set DNS but it stopped to work in Android 4.3 and further, so I created Override DNS, a new app which mimics Set DNS' behaviour,...

Starting with Android 9 Pie it is possible to change DNS globally, provided they support TLS. Just go in Settings → Network & internet → Advanced → Private DNS

Simple answer: No. 3G (also called UMTS) is a different techology than 4G (also called LTE). Both technologies don't share any common base technology (starting with the frequencies and going over to the encoding technologies). So your carrier has two different nets, one with 3G and another with 4G. If you are lucky being near a 4G base station you have an ...

The Short Answer Nope, not possible, or at least compicated & tedious, because Android defaults to WiFi since it's generally faster, more reliable and has no data cap However You may want to look into this app. While it requeires a rooted device, it allows you to leverage on both your WiFi & 3G to download at the same time. The Long Answer As ...

Just disable captive portal detection. In the terminal, or in adb shell, issue the command settings put global captive_portal_detection_enabled 0 and reboot.

I had the same issue. Found this solution on another site: Open "Settings" App Go to "SIM Card Manager" Tap on "Data Service Network" Choose the SIM as the Data SIM Note that only the first SIM slot supports 3G Internet. So if you want to use 3G you must plug your 3G SIM in the first slot.

Parts of those build.prop tweaks (and several you did not mention) are explained in the attachments to this XDA post. Let's see what of yours is covered – which are mostly the RIL settings (Radio Interface Layer): ro.ril.hep : unknown and undefined … may not even exist ro.ril.hsxpa : 1:HSDPA, 2:HSDPA/HSUPA, 3:? (HSUPA only?) ro.ril.gprsclass : see: GPRS ...

your phone doesn't support 4G it supports 3G++ which almost 4g and supports high speed downloads , the short unswer to your question is you can't use the 4g plan proposed by your carrier due to your phone's hardware limitation. the bright side is HSPA+ is not so bad you will not notice the difference.

Apps that use push notifications, such as the official Facebook app or Google+ Hangouts, don't need to repeatedly check for new messages. The server sends new messages to the phone when they arrive, without having to be asked. My answer to 'How do push notifications work?' describes this in more detail. What you're asking about is apps that poll for updates,...

Turning off 3g and reactivate it later would consume less power, as all the data can be fetched once the 3g radio is in the high power state When it is left idle, even for the most trivial data transfers, like checking the weather, the same cycle has to be repeated. Because of the long tail time that holds the device in a power mode, transmitting data as a ...

If you get a device working on a specific carrier or not depends on the following factors: cellular standards and frequency bands artificial locks on the device and sometimes willingness of the carrier First, check what your future carrier and phone have. For carrier networks and frequencies Wikipedia is the most complete source I know: http://en....

This info is from 2014. But it might still work. I am not in the position to test it at the moment, but since you are rooted. You could try adding the dns settings to the build.prop file and see if it sticks. Adding the following to the build.prop file should add google as your DNS server. net.rmnet0.dns1=8.8.8.8 net.rmnet0.dns2=8.8.4.4 net.dns1=8.8.8.8 ...

I figured them out thanks to here and here. GSM is 2G (on GSM networks) WCDMA is 3G (HSPA) CDMA is 2G (on CDMA networks) EvDo is 3G (on CDMA networks) TD-SCDMA is 3G (UMTS) LTE is 4G (LTE) This PDF (page 16) explains the evolution of the different technologies. Warning: A lot of this terminology is conflated (e.g. "CDMA" can refer to both the channel ...

With Xposed module and Gravity Box installed, the pull down status bar can be customised even on stock ROM (of course it has to be rooted). I have a Nexus 5 running stock 4.4.4 and following is how it looks: With these installed, one can swipe down with two fingers from top and just tap the last tile shown as "3G" in the image. Though this nearly misses ...

To limit the bandwidth, switch from 3G to 2G. You will still have internet connectivity but It will be slower, hence taking a longer time to use up your monthly internet traffic. The bonus is that using 2G will probably also increase battery duration as it consumes less power than 3G. On the other side, you can install a browser that has an option to load ...

Depends on network provider. From Nexus 7 2013 LTE Variant Available Now for $349: Keep in mind that you won’t be able to fall back to Verizon 3G at any time, but you can fall back to AT&T and T-Mobile HSPA should you choose their service. From Google's Nexus 7 with 4G is now available in the UK: Buying from O2 is a different story, however. The ...

I programmed Llama to do exactly that. You'll need two events: 3G auto on 3G auto off and one Llama variable: auto3G Event 1 (3G auto on) when airplane mode is disabled [prevents the system to work if airplane mode is enabled] when mobile data is not connected [this ensures there will always be a break of 60 minutes after each (manual) data or wifi ...

Keeping your IP address and using a VPN is the complete opposite of what VPNs are invented for. VPNs make you part of a network through a tunnel connection so that your phone is on the same level as locally connected devices. This means your IP address will be the one of the VPN. If you don't like this, then you should not use a VPN. Also check your IP on ...

The default setting provided in the Phone settings menus is Setting > More > Mobile Networks > Preferred network type > 3G Screenshot - Preferred Network Type selection(Click to enlarge image) This is a WCDMA(3G) preferred setting and that means it switches to 2G network if you have a weak 3G signal recepition in your area. For enabling 3G ...

If you keep your mobile data off, it rather depends on coverage: Good 2G coverage? Use that. Your battery will last much longer. Shaky 2G but stable 3G? Use 3G. Same reason: shaky coverage makes the phone permanently switch cell towers, which eats your battery. 2g & 3G shaky, but stable LTE? Well, you guess it. For a more detailed answer backed by "...

The "Smart Network Switching" is available since Android 5.0. You can see it in the official changelog here (in "see all features", "connectivity" : «Improved network selection logic so that your device connects only if there is a verified internet connection on Wi-Fi»).

I'm not sure if your issue was the same as me but I found your post because I had a similar issue. My 4G/LTE not working on my new FairePhone3 running LineageOS. I fixed my issue, here is the solution in case someone has the same problem. My phone would show the 4G/LTE as working but zero bytes transfered and no apps could access the internet. I double-...

Apps are incapable of switching moblie networks on/off as this uses up minutes. To bypass this you require a root. However I believe apps can detect if wifi is in range. So when you get near wifi you can have an app notify you. Although I don't think there is a specific app that will check if wifi is in range. I recommended requesting an app like this ...

Disabling Motorola OTA should do the job. Just go to the Apps section in your Android preferences and find the Motorola OTA entry under the 'All' tab. Disable it from there and you shouldn't get any more update prompts. (Click image to enlarge)

With regard to "Note that only the first SIM slot supports 3G Internet. So if you want to use 3G you must plug your 3G SIM in the first slot." In Settings --> More Networks --> Mobile networks You can set the "Network mode" for both SIMs separately, but only one card can be set to fast internet (WCDMA) at a time. This can be especially bothersome if you ...

If you are on Jelly Bean (MR2) or KitKat, you can use my app: Override DNS for KitKat. For lower versions of Android there are tons of free apps which do the same.

You might wish to take a look at apps like Network Signal Info and RF Signal Tracker, which allow you not only to monitor signal quality, but also show you which cells you are connected to, plus what kind of connection you had (3G/H+/...). You can follow that on-screen (to find the currently best place), and also log it (if you notice "drops", that might be ...

What version of Android you currently have on your Nexus device? I have (I think) exactly the same device, as you (ASUS Nexus 7 II (2013) LTE) and three days ago it was upgradred from 4.3.0 to 4.4.2 KitKat (I issued manual upgrade, by connecting to WiFi network and going to Settings > About phone > System Updates). After upgrade, option you're ...

After some testing over the weekend with a service provider who provides DC-HSDPA I can confirm that the Samsung Galaxy S2 does not support the protocol.
