[Q] Disadvantages N7105 (LTE) over N7100

I received a "N7100" today, which should have been the LTE version aka "N7105". I'm considering keeping it though...
What are the DISADVANTAGES of the N7105 over the N7100? I'm guessing:
- reduced battery life, but how bad is it really?
- higher price tag: I read on some UK forums a GBP 50 price difference on a branded device; anyone has a idea of the difference for an unlocked version?
- availability? I can't find an unlocked N7105 in stock anywhere here in Northern Europe, not even pre-order.
- fewer custom ROMs?
- no root (yet)?
- other considerations?

1. not noticeable for me
2. yes, more price for LTE, let see yr demand for that
3. regional problem
4. yes atm
5. root available at first day N7105 arrive

Hard to say what the disadvantages are between the N7100 and N7105 without owning both.
Currently, I have N7105 and having LTE makes more sense for future proofing (that's of course, if the network has it). I don't see major threads about LTE battery life but am used to charging each night.
There does seem to be less custom roms at the moment.
I got my N7105 on contract and didn't even see the option for N7100 so cost wasn't an issue. You may need to reconsider your plan though as running at 4G.
Just my 2c.

Sorry to say but LTE version has no FM radio...

in Singapore, we dont hv the option of N7100... so price vise is not an issue. matter of fact, i don't see any disadvantages between them. but for sure, N7105 gv u an option to use 3G or 4G in which... i hv tested, 4G can perform 5 - 10 times faster by using speedtest apps... as for more custom rom for N7100... that i hv to agree, at this moment... but i'm very sure... soon either existing roms to be compatible both version, or more new roms for N7105.
battery vise... i hv no problem at all. previous version i use, s2,n7000,s3...all also i use that bulky extended battery if i don't want to worry abt running out of juice. but this N7105...same usage as the rest... remarkably it can last me morning till night without using any extended battery.

I believe you can disable 4G and just have it on 3G/HSPA+ to conserve battery AFAIK.

I have owned both. I currently have the 7105 for future proof. My initial observation is that battery really drains quicker, but that is with 4g enabled eventhough I dont have 4g connection. I will observe more.... no need for roms because stock rom is excellent for me. For root, search for chainfire root guide for 7100, there is also a download specific for 7105 there.
What I dont understand is the settings for changing networks have only 2 options. 2g/3g/4g (auto mode) or 3g only. There should be 2g/3g mode as well.

I choose the N7100. Convincing arguments for me:
- battery drain (even though you can switch if off, just like 3G in the old days was an issue)
- FM radio (I'm streaming 99% of the time, but I still like listening to radio once in a while)
Ultimate argument: what is future-proof really? by the time 4G coverage is up to par (in my country at least), I'll probably be using a Note IV

I intend to keep my Note 2 for 3-4 years... can't really think of anything else I need on a phablet, and LTE will make it future proof...

LTE as standard in the UK
I believe the LTE version will become the norm in the UK at least. EE (The new Orange/T-Mobile) is now shipping the LTE version only and the other telco's will follow suit for "we are 4G ready" marketing purpose if nothing else. I would expect Samsung to push this model in other countries as well.
Not noticed any battery problems with my 7105, even with 4G enabled (I'm not in a 4G area though). I didn't realise about the FM radio which is a shame, but like I say, I had no option but a 7105 with EE.

Network (Singapore, M1)
Im using N7105: Here's my personal review on battery both 3G & LTE
Network on 3G: Battery time - 16 hours (Pure 3G) - 20 hours (With some wifi connection)
Network on LTE 4G: Battery time - 10 hours (Pure LTE) - 14 hours (With some wifi connection)

I've got the lte, I can't compare to non lte note 2, but the battery lasts a lot longer than my non lte s3(mostly because of increased capacity I know, but I never put my note down whereas I was bored with my s3).
The main advantage of lte version for me is faster downloads even though I'm on 3 and dont use lte, the hspa+ dc gave me a download speed last week of 20mb!
It should also have higher resale value next year when I buy the s4 or note 3

Stefan, Im from SG. Yes, Singapore only has GT-N7105 model. No FM. Unlock set. Around S$890+
So far, the stocks are very limited in SG. Good sales.

I only have the non LTE version, bought it sim free. Do I regret not getting the LTE model? Not really.
Yeah it will be worth more second hand but most the time I use the likes of mazhuma to sell my phones too and they will be little difference at sale time.
Also I'm on tmobile (ee) but am on an unlimited data plan that includes tethering so won't be in a rush to change to a ee 4g plan. If tmobile used dc-hsdpa which I don't think they do then maybe that's the only advantage for me but even with that, what I use data for either on the phone or via tether the speed given by dc-hsdpa isn't that important to me.
Then, although I'm locked into my tmobile contact for another 18 months I'm likely to swap my phone within 8 months anyway so the 4g picture will be a lot clearer then.

I had FM radio on my Galaxy Note N7000. And I think I used it twice in 12 month. I easily trade this for the LTE capability in my N7105.

I would rather have lte for future proof rather than manual radio. It is fiddly and you need the headset for it to work. I have tunein radio pro which allows me to listen to any online radio station in the world. Digital radio will take over analog radio anyway just like the tv signals.

Anyone has VoLTE on EE or Three UK?

Live in Edinburgh and just got my OP3. After put Three and EE sim cards into phone, I can't find "enhanced LTE" option in the setting menu. Does it means that VoLTE is not supported on EE and Three?

Yes, I can confirm that VoLTE and WiFi calling doesn't work on EE.
On Three you can probably use their app for VoLTE and WiFi calling (if you are not rooted).

Hi there. I can connect to the 800MHz LTE on the Three network, however there is no option for me to use native VoLTE or VoLTE via their InTouch app at all.
I doubt we'll see VoLTE natively on this device, but there may be a chance that a future update to inTouch would let it work there, but damn I hate their app.

Hi, how did you check you were on 800mhz on Three?

You can use this app to see your signal type: https://play.google.com/store/apps/details?id=com.wilysis.cellinfolite
Or use the dialer and use *#*#4636#*#* to view additional signal information.
It's somewhat of a guessing game also. I only get LTE signal here if its 800MHz as they recently rolled it out.

I have LTE on Three, but not VoLTE.
I also hate their awful app.

I'm trying to get VoLTE working with 3 on my OP3 too. From what I can tell, we need the APN settings for the 3 IMS APN. Damned if I can find these listed anywhere though. If somebody has an official 3 phone with working VoLTE then we can copy it off there.
I'm wondering if the Enhanced 4G voice option will show in settings when a compatible APN is detected? Other people seem to have VoLTE working on their OP3 (looking at posts on xda), but I'm not sure if they're using the stock rom or not.

The issue is that EE/Three really have no incentive to support the OP3 because they don't sell it.

Same goes for all UK networks none of them will enable VoLTE on the OnePlus 3

Just want to bump this thread as 3G coverage is rubbish around my home area. For some reason I only get 4G and am not able to get 3G. I have to use the Three In touch app to even receive calls

I'm interested too. My wife and I are both on three UK. She gets VoLTE on her Xiaomi Mi5 Pro but I don't see any options at all on my OP3

How do you get VoLTE on that? According to gsmarena it doesn't support band 20, and as far as I know Three only has VoLTE on band 20? It would be interesting if you could let me know if a) Three are now running VoLTE on band 3 too, or b) It actually does support band 20. Here's the gsmarena page: http://www.gsmarena.com/xiaomi_mi_5-6948.php
Thanks!

I've no idea. We were just sat in a pub and she asked me what the VoLTE in the status bar meant. Sure enough the icon was there and she gets it quite often

If you're on EE you probably won't get VoLTE; they're having trouble supporting the S7 so the OnePlus 3 is pretty much a lost cause. I know that kinda sucks for you guys on the better performing network
Three are more likely to; they support a lot more phones on VoLTE and are generally a lot more Android friendly than EE (EE always release Android updates very late, and everything is given to iPhones first).
But I'm obviously just guessing here, until VoLTE is more mature in the UK it's likely VoLTE support will be the complete mess it is now with only major phones getting it.
Hope that helped

why would you want 3g if you can get 4g ?

Last time I checked with Three they told me that only some phones approved/sold by them support VoLTE.
A few months ago they whitelisted the Oneplus 2 to use VoLTE though their app. The Oneplus 3 is not supported yet (not sure if it will be in the future).

Sorry. If you don't know voLTE (on the three network) only works on 800mhz, which only works on 3 carrier bought phones. 3G is the only way you can call apart from that, and as I already said, my area does not have 3G coverage.

4g calling now works on 3.5.2 on EE

Mi Mix 2 on Verizon 4G service

Has anyone been able to get 4G service working for the Mix 2 on verizon. I have googled and entered in all the APN's I could find. I keep getting the error message Access Point Name settings are not available for this user. I can get 3g service to work just by inputting vzwinternet and leaving everything else undefined, but I cant get it connected to 4G. Any help would be greatly appreciated

Hello...Yes. Verizon LTE works fine.
If you have the APN set correctly, try going into the testing menu (Dialer -- > *#*# 4636 #*#* --> Phone Information 1/2 --> ), entering whichever "Phone Information" relates to the Verizon SIM in use, and manually switching off the "Cellular Radio Power" setting (you may have to toggle it twice as it likes to turn itself back on)...waiting 20 seconds or so...and then switching the radio power back on. I can absolutely confirm that LTE on Verizon works fine though there does seem to be some funniness with respect to the Mi Mix 2's radio firmware when it has a CDMA SIM installed.

Arghhhh...how frustrating. The APN I'm using is "vzwinternet" so it's the same as the one you'd mentioned above...plus the LTE connection should work (though it may be inactive) even with the wrong APN.
I did run into this exact same scenario when I was messing around with two Verizon SIMs just for testing purposes and it seemed like the radio toggle worked...maybe keep trying it...and doing some reboots and stuff? The only other thing I can think of is maybe trying a GSM SIM temporarily (AT&T or T-Mobile) in place of your Verizon SIM to sort of "reset" it...and then putting your Verizon SIM back in...the other possibility is toggling the network types a bit in the testing menu? Mine's on LTE/CDMA/UMTS (auto) but maybe try going to CDMA only...LTE/CDMA auto...etc. to see if you can kick the radio in the butt a bit. I swear the Mi Mix 2 can connect to all of Verizon's LTE bands just fine...I've definitely seen mine on B13, 4, and 2...so it really can work...but there's some weird thing going on in the firmware that creates this issue I believe. I also had it when I first put my Verizon SIM in though a reboot initially fixed it...sounds like yours is more persistent...
Also - try untoggling VoLTE both in the Dual SIM menu and the testing menu - I think sometimes these dual SIM phones have some issues with VoLTE sort of holding the LTE connection "hostage," even if only for emergency calls...though this is just speculation. My old Axon 7 from ZTE had this same sort of issue from time to time.

Does the bootloader need to be unlocked &/or TWRP installed to move from factory stable to the Developer ROM,or,just follow the guide in the link you provided?
With my previous Xioami devices,I never used the Dev ROMs,went straight to the Bootloader unlock > TWRP> Root > ROM of your choice route,so,just wanna get the methodology correct before proceeding.

No you don't need bootloader unlock to switch to the beta ROMs. You just need to download the relevant zip file and place it in a particular folder on your SD card (downloaded_rom) and then run the update manually from the settings menu. The instructions at the following URL work quite well except that I just downloaded the zip file directly to my SD card from the browser versus using a computer and then transferring it with a USB cable.

Though the developer Rom may fix the problem, I'm wondering if the Mi Mix 2's dual SIM setup is as buggy as the ZTE Axon 7's when trying to get Verizon CDMA working. With the Axon 7, you had to set it up initially with a working GSM Sim in slot 1, before you could switch over to a Verizon SIM and get it to hold the new APN and function properly. The Axon 7 was also configured such that your CDMA SIM must be in slot 1. It would not work at all in SIM slot 2. I'm thinking that these Chinese made dual sim slots may be birds made of the same feather.

Hello...I have an Axon 7 A2017U and a Mi Mix 2...I'd say the Mi Mix 2 is a bit better in this respect (I ran Verizon on my Axon 7 as well). But, I did have some of the same issues as the OP when I initially put my Verizon SIM in and a reboot and radio settings dance seemed to fix it.
However, the Mi Mix 2 generally does not have the CDMA roaming issue that the Axon 7 had, nor the '123456' carrier issue that the Axon 7 had (i.e., it shows Verizon on 3G and 1X).
So, there is some of the oddities that I ran into with the Axon still sort of present in the Mix 2 but it's not bad...I think it's related to VoLTE but that's just a guess...but all in all the Mi Mix 2 does work a bit better than the Axon 7 did with Verizon...though I never had a great deal of trouble running Verizon on the Axon 7, admittedly...I think some people had a lot more difficulty than I did for some reason.

Oh! And one more thing...you can use either SIM slot 1 *or* 2 in the Mi Mix 2 for Verizon...you can actually run two CDMA SIMs but they won't be able to work at the same time...only one will get calls and texts.

When you loaded the Developer ROM did it wipe all the exisiting data and accounts on the phone.
I just spent two days setting the phone up, don't want to do that again.

Same here, basically just finished setting up & get to do it again.

Did the backup restore anything from the cloud.

I didn't use Mi Cloud, or, any cloud backup service.
I just manually set up, after disabling as much Mi/MIUI bloat/snoopware as possible.
Most of my needs are met when I log in to Google. The rest is just downloading apps & installing Nova Launcher Prime.

Hello...I have an Axon 7 A2017U and a Mi Mix 2...I'd say the Mi Mix 2 is a bit better in this respect (I ran Verizon on my Axon 7 as well). But, I did have some of the same issues as the OP when I initially put my Verizon SIM in and a reboot and radio settings dance seemed to fix it.
However, the Mi Mix 2 generally does not have the CDMA roaming issue that the Axon 7 had, nor the '123456' carrier issue that the Axon 7 had (i.e., it shows Verizon on 3G and 1X).
So, there is some of the oddities that I ran into with the Axon still sort of present in the Mix 2 but it's not bad...I think it's related to VoLTE but that's just a guess...but all in all the Mi Mix 2 does work a bit better than the Axon 7 did with Verizon...though I never had a great deal of trouble running Verizon on the Axon 7, admittedly...I think some people had a lot more difficulty than I did for some reason.

Oh! And one more thing...you can use either SIM slot 1 *or* 2 in the Mi Mix 2 for Verizon...you can actually run two CDMA SIMs but they won't be able to work at the same time...only one will get calls and texts.

Great post! This is really good to know, since I will be running a GSM and CDMA Sim simultaneously in the Mix 2, just like I did in my Axon 7. My Axon was very slow and flakey switching between Sims and yea, that 123456 carrier thing was for the birds. The other issue with the Axon 7 was cellular signal strength. I was getting 5 to 15 db lower signal strength everywhere and since it didn't have LTE band 12 for T-mobiles 700 Mhz channel, the in building reception was even worse. How are you finding the signal reception with the Mix 2?

Hm...my Axon 7 did have band 12 support - did you have an A2017U?
As far as the signal strength, on CDMA/EvDO and also LTE I do notice about a 3-5 dBm increase in the signal in the Mi Mix 2 vs. the Axon 7 (pictured below - Mi Mix 2 on left, Axon 7 on right...opposite in the last two pictures in case positioning had an effect on signal). Of course, the test is highly unscientific! But, yes...there does seem to be a bit better reception which maybe is due to the use of ceramic vs. metal? Not sure...or just better engineering or modem firmware optimization...not sure.

Yes, that's the model. I guess I was confusing it with one of my other phones. The LG V20 I used right after selling the Axon 7 had WAY better reception indoors so I thought it was a band 12 issue. I think the Snapdragon 835 chip with the X16 modem does a better job of optimization in the Mix 2, but I don't know if it has all the hardware- like 4 antenna mimo- for LTE CA. The ceramic is certainly more transparent to cell signals than the Axons metal chassis. Thanks for your informal "scientific" study.

How's the data (LTE) connection?

So I am planning on ordering one of these soon but having read the forum there's been some concerns around LTE connection. I was quite pleased to learn that 20x was supporting a a lot more bands than any other "normal" Chinese phone would. That said, I am getting second thoughts now to learn that people are not getting the best LTE connection (HSPA + on Att?) and a lack of band 28 which may not make for an ideal LTE experience.
What are your thoughts and how's your experience been when it comes to data (particularly the LTE) connection?
Thanks in advance.

The icon shows 4g lte. The phone loads lightning fast. Im on band 17 which is the 700mhz. I average 12 to 20 DL speeds.

So which model number that you have? I assumed not the Chinese one but the Global one correct?

AL00 (Chinese Version) Seems fine to me:

Been using the EVR-AL00 version in Canada Dual sim and I am able to get the best speeds on both my sim cards LTE+.

Many things, read through the forums, for me the differences are livable, to others its not. Buts all based on what you want from the phone and what you use. I dont live on my phone, so for me for example, "whatsapp" is useless, to others they cant live without it. But for everybody the need is different.

LTE+ on bands 4 and 7 in Canada, New England, and New York. Very fast data connection. L29 model.

I was worried about speed too before I bought. Band 28 is very common in Australia so the fact it is missing from this phone had me worried.
Thankfully my experience has been wholly positive - check out my up/down speed on dslreports here: (I can't post links so you'll need to take out the linespaces and add back the periods)
www
dslreports
com/speedtest/44320783
Notice that mine is currently the fastest speed in the last 400,000 tests nationally using my mobile provider (Telstra Bigpond). The second fastest is an iphone, clocking in at half the download speed I'm getting using my Mate 20 X.
(Note: I have the "LTE high-speed mode" enabled in settings)

I'm in the UK and use bands 1 & 20 on Vodafone, very quick speeds and never noticed any issues with connectivity

ATT 5G nonsense

I was with a friend who has a new iPhone that was showing 5G. I have the dual SIM international version on ATT and I know it misses band 30 so I was interested to see just how much faster his network speed was. We both ran SPEED TEST and I got a miserable 15MB download and 10MB upload. Meantime.... He couldnt even get more than 2MB on both. He wasn't very happy! We tested web browsing and mine was faster. What a con!

It's not true 5G, it's 5GE it's just a fancier albeit deceptive way of saying 4G LTE+ (if I'm wrong on the LTE+ part my bad I know it's still 4G though) real 5G still has a little bit to go before it's full 5G

The 5gE will show up on the S10+. I saw it show up on my 9+.

You're absolutely right. They're basically pulling the same Stunt they did when the started labeling HSPA+ as 4G when it was in fact more like 3.5G. Total sham. In order to be considered 5G you need to have a minimum speed of 1Gps. I get about 540Mps on LTE+ in Canada. I don't think AT&T can even come close to those speeds. And it's not even 5G.
Sent from my SM-G975W using XDA Labs

My wife has an Att S10+ and I have a G975F variant.
the status bar shose 5G - but speeds are just typical - however, I have noticed that it is faster than my phone/ I was outside the other day and my wifes phone got 120MB download and 75 MB upload - I did a speed test on my phone at the same spot and I only got 60MB down and 30MB up.
I think it might be because the G975F varient is missing one band that is on the ATT Variant. It isn't reallt 5G but it is a bit faster on ATT phones. I think becuase it is Enhanced LTE....hopefully some day we will be able to flash ATT CSC on the G975F phones....I
don't remember which band is missing from the G975F variant, but it does definately mean that devices that are from the F Varients are not as fast on LTE as the ATT PHOnes.

Yeaaaaaa I was right. But in all seriousness it's shady as hell business practice (but then again almost all the carriers in the US were guilty of it at some point)

AT&T should be held accountable by somebody for their scummy practices - or at least called out for it. It's ridiculous!

My phone got 7g's on att

Are you living under a rock? The other 3 major carriers called them out on it already, months ago. There's even an xda article from earlier today where Sprint and ATT settled a lawsuit about misleading customers about 5g "E".

No. I just haven't seen it. Have you seen everything, everywhere?

This 5G stuff is fluff anyways. I live in a rural area with barely any LTE coverage. Will most likely never see 5G here. I deploy IOT hardware (autonomous air quality/meterological arrays, for example) and they all use 2G GSM hardware. They just post data to an offshore server. Point is not all applications need low latency gigabit wireless. That's what my Xirrus wifi is for.
And where LTE service is good, I'm seeing nearly 200Mbps /50Mbps (down/up) speeds with latency averaging in the mid 20s to low 30s. That's good enough for me. Just remove the stupid wifi needed to get big updates and we're good. With unlimited plans these days it's ridiculous to have to tether off another LTE device to get larger updates.

Att recently updated to 4x4 bands and 5ge is their way of showing it instead of something like 4g+
