Slow lte speed in s6 - Galaxy S6 Q&A, Help & Troubleshooting

I'm facing slow lte speed on my s6. I'm using reliance jio in India and it support only lte network. When I checked the speed using ookla the speed ranges from 100kbps to 1 mbps in my s6. Im using galaxy s6 g920f purchased from UAE and now it runs on nemesis 7. 0 s7e port os. My friends using j7, moto e4 are getting good speeds ranges from 10mbps to 20mbps at the same place. I inserted my sim in other phobes and the speed is very high. So the problem is not with the sim or operator. The APN is also same as theirs. Can anyone help me to troubleshoot the issue? What might be the issue? thanks in advance

[Q] Telstra 4g reception issues

Hi just wondering out there how many ppl in general with the note edge are getting low 4g or lte signals. Recently just got mine and my signal is real low between 1-2 bars sometime in the city where 4g is strong i still get 1 or 2 bars. If I compare it to my old phone I'm getting full reception and real 4g speed. Not sure if it just my phone or is it a common problem everyone else has. Any feedback wil be good. I am in Australia on the telstra network. My edge is N915G running on baseband ANK4.
Same issue i think
I have the SM-N915S model from Korea and i am in The Netherlands on T Mobile.
My note 3 works on 4G yet when i install same sim card into Note Edge i dont get 4G (Or LTE as its called on phone)
I am wondering if its because the network frequency in Korea is 850/900/1800/2100 and Netherlands is 800/1800/2600??
There is also no option to make it automatically switch between the 2. It only has the option for LTE or 3G.
I am also wanting to know if rooting the phone would enable the access?
Is there a way to root the phone and turn it into the SM-N915Y model for Europe in the hope this will fix the issue?
I am new to this and studying up on rooting phones.
Any help would be appreciated...
i am hearing it is a known issue with the Note Edge across all platforms. I am suffering from the same thing.

4g+ problem

my oprator 4g+ work on band b3 & b7 but my phone just show 4g on statu bar but other phone like samsung show 4g+ on same area.my rom is 8.2.2 global stable.
is mi 5s plus suppport 4g+?
Maybe don't support
But I cannot call or receive calls only one SIM card work for call I use two operator
Irancell SIM card on slot 1 have internet and call other slot don't work internet and call then change sim card in slots HAMRAHawal can call in other slot irancell only have 4g internet and cannot call
When say problems with this phone in Miui forum manager banned me and don't help
I very very angry when saying problems and manager miui banned me why ?!!!!!!!!!!!!!!!!!!!!!!!
The xiaomi is cheating and cheaters the people of word and don't help the rubber is better than xiaomi
Pretty sure only SIM slot 1 supports 4G, slot 2 is 3G. I didn't buy it for the dual SIM stuff so I have only tested the first SIM slot and have had no problems with 4G.
As for 4G+, that is just a branding thing. 4G+ is 4G. there is no difference. The only reason that some phones put 4G+ on their status bar is just that they modified the icons in the ROM.
see - https://en.wikipedia.org/wiki/4G
If the phone says 4G, you are gettign 4G. The important quote on that page is:
Confusion has been caused by some mobile carriers who have launched products advertised as 4G but which according to some sources are pre-4G versions, commonly referred to as '3.9G', which do not follow the ITU-R defined principles for 4G standards, but today can be called 4G according to ITU-R. Vodafone NL for example, advertised LTE as '4G', while advertising now LTE Advanced as their '4G+' service which actually is (True) 4G. A common argument for branding 3.9G systems as new-generation is that they use different frequency bands from 3G technologies ; that they are based on a new radio-interface paradigm ; and that the standards are not backwards compatible with 3G, whilst some of the standards are forwards compatible with IMT-2000 compliant versions of the same standards.
4G+ is just true 4G. So if the Mi 5S Plus says 4G, you are getting 4G (or 4G+ as they are identical).
You can verify this with any LTE bandwidth monitor apps (such as signal spy) which will tell you that you are on LTE and which band you are on and you will know then that you are on 4G.
Hi mates. I'm living in Netherlands ...have problem with 4g..
My phone doesn't support band 20 ( 800 mhz )..
Is there an option to access 4g?...
Maybe flashing a custom ROM ?...
thanks
bmg002 thanks for your help.the app like signal spy does not work on my phone because of my phone is not rooted.do you know any app that i see network aggration without root?
offhand, I do not know of any non-root tools for getting any information about what network you are on.
My next best bet would be to get some bandwidth testing tool (speedtest for example) and then check what speeds you are getting out of 4G and compare that with what your provider claims you should be getting. My provider gives me 750 Mbit/s as a peak speed, and 250 Mbit/s average. If your speeds are close to that, then that is all that really matters. If it indicates 4G or 4G+ or 4G LTE or whatever indicator it says in the top, if your speeds are slower than what you are paying for, you will want to look at rooting and opening up some of the 4G channels which will likely give you better speeds.
If you still have your old phone, do a speed comparison in speedtest (or equivalent) and see if it is faster or slower on the new phone. If it is marginally slower (or faster) that can likely be ignored. If they are drastically different, then I'd look at rooting and unlocking other channels.

If you need to access 4G and your operator only supports band 20, then your only option is to use a different phone. From everything I've read on this forum, the hardware has been modified to not support band 20 due to licensing concerns. So a custom ROM or custom Kernel will not affect being able to use band 20. There is no way around it at this time that I am aware of.
Now, if your provider uses a band other than band 20 (or uses 20 and another band), then you can open up the other bands. There are several posts about doing that.

Everything you say is just false.
it is really easy
4G : 150MB/s max
4G+ : (phone connected to two 4G frequencies) 300MB/s max
4G++ : (three 4G frequencies) 600MB/s max
Xiaomi MI 5s is supposed to support up to three 4G frequencies at the same time BUT, in a lot of case, like here, in france, band 3 (1800Mhz) and band 7 (2600Mhz) are the two compatible 4G freq, BUT Mi5S Plus can't connect to 2 freq simultaneously and we don't really know the reason, in china it's not FDD LTE but TDD lte and it works, maybe it just doesn't work on FDD...
This is what we are asking to dev, find a way to enable dual or triple 4G freq in FDD LTE to acces high speed 4G.
I'm sure it's somthing to do with modem or kernel modification :S
Best regards
At the risk of starting a flame war, could you cite your sources on that?
I believe the speeds you quoted are wrong. Telus up here in Canada operates on 4G LTE version 8 which supports up to 750 Mbps max, but to expect average speeds around 200 Mbps (http://www.telus.com/en/sk/mobility/network/). NOTE - 750 Mbps is 93 MB/s approximately. Mind you, independant studies show that average speeds are closer to 20 Mbps for telus ().
Now, correcting my previous post - I was incorrect about our phones supporting 4G+. I misinterpreted the wikipedia article.
Looking at GSM Arena for our phone, it only supports LTE and thus not 4G+ (http://www.gsmarena.com/xiaomi_mi_5s_plus-8350.php). If you look up the galaxy S8+ for example, it supports LTE-A which would be 4G+.
We can read about LTE-A here - https://en.wikipedia.org/wiki/LTE_Advanced
and you can see which speeds different carriers offer here - https://en.wikipedia.org/wiki/List_of_LTE_networks
For example, Telus, which I am on, only recently added support for category 11 - 600 Mbps.
The 4G++ that you speak of I believe is LTE-A Pro (https://en.wikipedia.org/wiki/LTE_Advanced_Pro). But they are not referring to it as 4G++ but as 4.5G or 4.5G Pro.
Looking at this article - https://en.wikipedia.org/wiki/List_of_devices_with_LTE_Advanced#Xiaomi - it appears that our phones do not support 4G LTE-A. What is a little confusing is that the 5s does support LTE-A.
I could be mistaken, but I am pretty sure it is a hardware restriction to not support LTE-A.

After some search, Mi5S Plus is only 4G+ intraband and not with interband 4G+
I sold mi5s plus and buy redmi 5 plus better
I don't say mi 5s plus used for 4g or4gplus
I say only my phone don't getting call
Or internet in sim1 by one operator change operator in sim1 to irancell operator only have internet cannot call or get call
The problem is from www.hamta.com must phone registered in this site in Iran for use
Hello dear u should unlock all lte band for using 4g+ in iran i tested this phone in uae and china have 4g+
How can I do it? I just installed Lineage 17 and only appear LTE. I am in Italy and with a brand new P40 Pro Huawei peak download is ~150 mbps but with mi5s plus this is the best can achive.
While Qualcom specs speak of 600mbps for the X12 modem inside the Snapdragon 821

Thanks to this thread https://forum.xda-developers.com/t/guide-how-to-unlock-bands-and-5g-on-700mhz.4114679/post-84040943 and Network Signal Guru app, I know that available bands for this phone are unlocked.
Why only poor performance on this phone? How to improve them?

S8+ not giving LTE on Rogers

Hi everyone,
I have an S8+ I bought abroad, when I use my Rogers sim I get 4G not LTE. However when I use the sim on my Priv, I get LTE. I am using the Rogers APN.
Is there anything I can try?
Thanks
What country code/model is the phone? It's just an icon - whether you see 4G or LTE icon all depends on the CSC the device came preset with.
The only potential issue is with the European models (G95XF / G95XFD) lacking band 30, which some carriers (like AT&T) use for Enhanced LTE. While Enhanced LTE does work, it doesn't support the full speed that comes with band 30.
Do a speed test. If your S8 and Priv report the same speed, don't think about it too much.
The phone I bought from Saudi Arabia. Model is SM-G955F.
I do get similar speeds.
Can I change the preset without rooting the phone?
Thanks again
Usually f models shows 4g icon rather than the LTE icon.....so you are perfectly fine
Signal icons are usually csc dependant... you can see what csc is on the phone and search online to see which csc has the icons

Mine works perfect on rogers.
Its a device from panama and it displays LTE. A few of my previous F versions did show 4g....but same deal
sent from my Note FE, S8 plus, S7 edge or S6

Mm, yeah.. I know it's some cscfeature, just can't figure out which one. When using BTU, it shows up as 4G, but switching over to a XAA csc changes it to LTE. Speeds are the same.

Middle Eastern phones like the one you bought don't show 'LTE', they show 4G in the status bar, but to confirm you can open the dialer and dial *#0011# and see LTE-BASIC Info, like what LTE Band your phone is using and other detailed information about the cellular connection.

LTE / 4G problem

In quite urgent need of help. Got 2 Galaxy S8+ phones here. I am in Australia. Australian Galaxy S8+ Model I have is the G955F, the other model which I think is USA is a G955U1 or UI I think. It was sold on eBay as an Australian model and I don't think it is after doing some research.
I have noticed that when putting the sim card in the Australian model it shows up on the top bar as '4G' for the network and on speedtest I get a down link rate of 94 mbps.
With the American model I use the same sim card which shows up as LTE instead of 4G and when doing a speedtest I get a rate of 20 mbps.
Bit frustrated about this as it seems it is not able to get the full use out of the frequences here in Australia which is affecting signal, calls and network.
As you lot seem very clued up on this can I ask if you know a fix? Software wise or hardware? Without having to replace the actual mobo and phone.
Thanks

T-Mobile Users

Hello, so I'm currently looking to replace my phone and the only phone that fits my needs is the z6. My only concern is comparability with tmo. Do any z6 owners use tmo? And if so, how is the lte? If anyone can help I would really appreciate it. Thanks in advance!
My last phone was oneplus 3, and I'd say speed is about on par, both get LTE. But no voLTE for zenfone. There are places where I'm getting receptions and oneplus 3 didn't. I don't think you will notice much difference, unless you are in a place where band 71 is normal.
I get better data speeds than my gfs Galaxy s9. I'm in Chicago
For the most part it's ok speeds could be a tad faster at times but 90% of the time coverage and speeds are fine
No volte or wifi calling

works well with TMobile
All good for me. As above, only thing is missing volte and wifi calling. Using the phone successfully on tmo in Southern California and roaming in Taiwan and China.
