Just so people aren't confused... 4G and LTE are 2 different things.

4G = HSPA+ and is around 5-10Mbps.

LTE can be 20-30Mbps and also has much less latency.

Most people are looking for LTE in the USA and these international phones only support 4G (Which is slower than LTE but works good enough for me)
[Asus ZenFone 3 Ultra Questions & Answers] Slbtrb79:
Thanks for your comments. I accept mostly what you wrote for most companies definition of 4G and LTE. I was going by my carriers definition or interpretation of what they call 4G LTE and just 4G. The confusion is more from the caps on the data speeds various companies have. Because to me there is little difference between saying LTE and 4G LTE.

Cricket is the carrier owned by AT&T. They call their data speeds 4G and 4G LTE. AT&T caps Cricket download speeds at what they say is 4G LTE at 8Mbps and 4Mbps download speed cap for just 4G (Referenced from Crickets's website and from www.gottabemobile.com 6/21/2015 article on this topic).

However, my earlier remarks about my Asus phone was incorrect, due to Asus limitations on their 4G/LTE phones sold to individuals in the US, even though the carrier here might support some of the same 4G/LTE bands. It's an Asus thing and probably some others too. I'm probably only getting just 4G or less. My speed tests are only showing 3Mbps and a little better on download speeds on Cricket Wireless with the Asus Zenfone 3 ultra. But I was only getting on speed tests 4Mbps and a little better download speeds with my previous HTC 10 on Cricket Wireless. I have never even gotten close to Cricket's 8Mbps on my HTC 10.

At this point I'm ok with HSPA+ (It's what i've used for years now in the US with International phones)

I'm waiting for root to surface for this phone and then i'm jumping right in :)
[Asus ZenFone 3 Ultra Questions & Answers] Apo11on:
Please do not confuse people with false information. HSPA+ is officially considered 3.5G connection type. Long Term Evolution (LTE) is defined as a 4th generation (4G) wireless connection standard. Those are official nominations, you can find through IEEE site, Wikipedia and many other reliable sources. LTE theoretical max speed are nowhere near 20-30Mbps figure you provided - they are *much* higher. There is also LTE-A (advanced), which is also 4G but doubles the LTE speeds, and the actual LTE speeds depend on the hardware and LTE category of the modem.
[Asus ZenFone 3 Ultra Questions & Answers] omniphil:
Apple calls HSPA+ 4G, Yes i know its not technically correct, but that's what most people associate it with.

LTE can go much faster then 30Mbps for sure, I used to get 60. But nowadays with all the people using it 20-30 is a reasonable average for what most people actually see. (The point is its much faster than HSPA+)

I only bring this up because folks ask if they can get 4G on these international phones (As not everyone is a phone nerd like us) What they are really asking is if they can get LTE on these phones and most of the time that answer is no.

Basically I want people to understand that we are talking about HSPA+ vs 4G LTE and how that relates to international phones.

Is that good?
[Asus ZenFone 3 Ultra Questions & Answers] Apo11on:
Apple or any other hardware manufacturers, as well as phone carriers can deploy any marketing schemes they like and call the lousy HSPA+ "4G" all they want, but it won't make it true. Neither of them gets to decide, and "most people" don't get to decide either. For the record, I disagree that most people think HSPA+ is 4G - most know better, in my opinion. The international governing body for wireless standards gets to name wireless technologies, protocols and classify by generation.

If you want people to understand that HSPA+ is different from LTE then saying "LTE can be 20-30Mbps" is not the way to go, because that would achieve the exact opposite. Theoretical max HSPA+ speeds achievable by this technology are 168 Mbps down and 22Mbps up, so defining LTE as 20-30Mbps connection makes your LTE no better than mediocre HSPA+ link. Some FDD-LTE and TDD-LTE links, based on the utilized spectrum, currently go up to 450Mbps down and 150Mbps up. Theoretical limits are much higher and LTE-A is twice faster.

While your intentions seem to be good, that still doesn't excuse providing inaccurate information, while also saying you dont want people to be confused. Confused is exactly what people would be, if they believe the info in your post. If you want to answer a question "will I get LTE in US with this phone?" - a simple "No" would be much better answer than inaccurate information you provided to "eliminate confusion". Or you could say something along those lines:

"ZenFone 3 Ultra is a GSM phone, so only AT&T or T-Mobile in US could be compatible, because Verizon and Sprint use CDMA technology. AT&T's LTE network operates on bands 2,4,5,17 (recently forced to support band 12 as part of FCC roaming support requirement) and T-Mobile's LTE network operates on bands 2,4,12 (recently forced to support band 17 as part of FCC roaming support requirement). Asus ZenFone 3 international version on the other hand, support LTE bands 1,3,5,7,8,18,19,20,26,28,38,40,41 - do you see any overlapping bands besides B5? B5 is utilized by AT&T in limited number of US regions and even there you will get extremely spotty LTE coverage, because LTE bands operate in conjunction with each other and there are constant layovers and fallbacks between frequencies, based on towers proximity".

Hi!

I bought a Huawei Mediapad X2 7" display phablet last November. I used it for a month on Cricket and couldn't get good MMS service... I wouldn't get group texts or pictures... How is your Ultra doing in that regard (on Cricket)? No good MMS is a deal breaker for me... Also, the X2 came with Google and Google Play Store already installed. I am not a techie but asked a LOT of questions on xda and was walked through a successful setup (I learned a lot from other people's questions, too)... I don't root my phones... So I need good out of the box service. I have been looking for a 128GB Ultra just to compare prices to a 64GB Ultra. Have you seen any? I am waiting for the Lenovo Phab 2 Pro to be re-released but I really would love this Ultra, instead (if it works on Cricket the way I need it to)... Thanks for your time!
[Asus ZenFone 3 Ultra Questions & Answers] Slbtrb79:
I have had no problems with Cricket on my Zenfone Ultra. MMS, SMS, work just fine. No problem with sending group texts and pictures. However, you will not get LTE on the Ultra, in the US. For me, the 64gb on the internal side with a 64 GB SD card, gives me plenty of space. Google and Google play came pre-installed on my Ultra. So far, I have received great service from Cricket on my Asus Zenfone 3 Ultra and my HTC 10. I love the music app, the audio wizard, and the stereo speakers. Takes great pictures. It's like having a 7 inch tablet with 4gb of ram and it's a phone. Due to the size, the music features, the picture features, the huge battery, I use this phone more than my HTC 10. The only down side that I have with this phone, is you can't get LTE here in the US and you can't unlock the bootloader yet. But personally, I was initially looking for a 7 inch tablet with 4gb of ram, stereo speakers, that also took good pictures and has a big battery. I ended up with the Ultra.

If screen size is important to you might look at the Xiaomi Mi-Max, it has 6.4 screen and nice specs. Also Huawei Mate 9 with a 5.9 inch screen with nice specs also.

Hope this helped some...

Thanks so much for your time on the detailed answer!!!
[Asus ZenFone 3 Ultra Questions & Answers] Slbtrb79:
I'm only a junior member with limited experience with these technologies, But I am just a little confused with these previous comments in regards to these discussions on HSPA+, LTE, and even Wimax for that matter. Believe me, when I say that I still have much to learn on this subject. Just because HSPA+ is different from 4G, I was always under the impression from everything I've read, that they are all still labeled as 4G technologies, as defined by the ITU. With all the above, having wide variations in consumer speeds. Also, whether a certain phone manufacturer supports a particular LTE band is just part of the whole part of the 4G technology. (Information taken from, in part, from Android Authority and Tech Radar)
[Asus ZenFone 3 Ultra Questions & Answers] Apo11on:
Phrase "HSPA+ is different from 4G" has no meaning. Those are not comparible things "HSPA+" is an abbreviation for wireless protocol name, and "4G" is a generic reference to 4th generation of wireless technologies, which include several protocols. it's like comparing TV weight to picture brightness.

Judging from the phrase "whether a certain phone manufacturer supports a particular LTE band is just part of the whole part of the 4G technology" I'm not sure you understand how things work. Since approximately 4 years ago, ALL major SoCs (system on chip) support Worldwide Global LTE, all 41 bands. Here is an example of Qualcomm's Snapdragon SoCs, scroll down to "Global Mode": https://www.qualcomm.com/products/snapdragon/modems/4g-lte . So, all major SoC manufacturers have been "supporting" ALL LTE bands for approximately 4 years now. Mobile device manufacturers, who partner with SoC makers like Qualcomm, or produce their own (i.e. Samsung: Exynos) control what LTE bands are actually enabled using modem's firmware, which is purely a software issue and can be changed at any time with NVRAM hack or firmware update. They decide what bands to enable based on the country the device is targeted for. Operating frequencies in each country are tightly regulated, because otherwise there are security issues, surveillance issues, interference issues (that's why they ask you to shut your phone down on a plane) and LTE frequency bands spectrum is divided to over 100 chunks, and each country/region are only allowed to operate on a specific, limited number of frequency bands. Therefore, any phone manufacturer, who wants to release wireless device with certain LTE bands enabled in a specific country, first must abide by the frequency bands international rules and then before they are allowed to sell and operate their device, their device must be approved by each country's wireless regulations governing body, which will thoroughly test the device, to make sure it meets all the required technical, safety and security standards. For example, that governing body in US is called FCC and in China it's TENAA. To sum up, what LTE bands each phone maker enables for which country, has nothing to do with being "part of the 4G technology".

Xiaomi Mi Max is a bit of an old news. This Xiaomi phone is the future. Same 6.4" screen size as Mi Max, but device size is comparable to 5.7" phone, not to mention numerous other innovations, such as ceramic body and audio transmissions via ultrasonic vibrations, instead of conventional speaker.
[Asus ZenFone 3 Ultra Questions & Answers] VillaRegina:
I kept hearing about this MiMIX but just in general so I thought it was a typo of MiMAX! lololol! WOW! What a phone! Is it actually available and what does it cost? 6GB/256GB!!! CRAZY!!! With such a great screen ratio! Do you know anyone who actually has one in the USA? WOW!

Thank you for your time and detailed explanation! I would probably have to read it 10 times to understand every detail (although you did a great job breaking it down for this non-techie). I think that it answered a question that I have always had... Whether you could actually change the bands supported with a software change... But I am not sure that I got it... Yes? I wish the bands were USA bands (obviously) because I had terrible MMS performance from the only Chinese phablet I ever tried (even though it worked well elsewhere in the country - I sent it to a friend to test it before I could - in good conscience - sell it)... The bands just didn't seem to work in my area... And I always wondered if there was a change in law if my phone could be updated with a software update (although wishing for almost any update when you get the phones over here might be moot)...
[Asus ZenFone 3 Ultra Questions & Answers] Slbtrb79:
I believe your talking about the Mi Mix, due to the ceramic body and the audio technology. I did not mention this phone to the person I was responding to, since It will only be sold in China.....
[Asus ZenFone 3 Ultra Questions & Answers] Slbtrb79:
Thanks for the time taken to explain about LTE bands. I had that all wrong. But I will stick to my statement that HSPA+(evolved high speed packet access), WIMAX, and LTE(long term evolution) are all labeled as 4G technologies. Thanks

---------- Post added at 03:42 AM ---------- Previous post was at 03:33 AM ----------

Thanks, but if you look at the post, I was responding to a member looking for a large phone who was looking at the Asus Ultra. I also gave some alternatives to look at with large screens. I believe your post refers to the Mi Mix with the ceramic body and audio technologies you mention, but that phone will only be sold in China. So, I did not mention this phone since it will probably not be accessible to this member or anyone else in the US. But it is a beast.

---------- Post added at 03:48 AM ---------- Previous post was at 03:42 AM ----------

In reference to the Mi Mix. Beast of a phone. But not mentioned in my post to you earlier, due to not being offered outside of China, hence the Mi Max reference.
[Asus ZenFone 3 Ultra Questions & Answers] Apo11on:
Xiaomi Mi Mix already has it's own forum, so you can post your questions about the device there. Let's not hijack this thread - I created it for LTE stuff, related to Zenfone 3 Ultra. To answer your question - Yes, for both Snapdragon 652 in Asus Zenfone 3 Ultra and Snapdragon 821 in Xiaomi Mi Mix US LTE bands can be unlocked by software modification. However, just because something can theoretically be done - doesn't mean it's easy to do, or that someone will actually do it. Official firmware wise, Asus and Xiaomi would never do it, for the reasons I explained in previous post. Hacking wise - only experienced dev, with in-depth understanding of this specific SoC, who has ARM assembly reverse engineering experience, could reverse baseband firmware, and then come up with a method to calculate and manually hexedit the NVRAM values, required to enable additional LTE bands support. Speaking as engineer myself, it's a lot of hard work, trial & error and possibly bricking your test device many times along the way.

[MENTION=6291804]Slbtrb79[/MENTION] Mi Mix is indeed released for Chinese market only, however it supports wide range of LTE bands, including FDD-LTE bands 2 and 4, used by AT&T and T-Mobile in USA. It has already been reported Mi Mix can get LTE signal on these 2 US carriers.
[Asus ZenFone 3 Ultra Questions & Answers] Slbtrb79:
Please, Neither was I hijacking this thread or do I have questions about the Mi Mix. It was in response to your comments about the Mi Max being old news and your Mi Mix comments on this US LTE on Asus Ultra thread. My comments were directed at a member who had questions about the Asus Ultra on the US LTE Asus Ultra thread. I responded with my opinion about the Asus Ultra and gave options on other Big screen phones, but did not include the Mi Mix, but instead the Mi Max due to it's availability. Then your response came with the Mi Mix, even though it's not available in the US, but only in China, which would not help the member looking for a bigger screen phone. I responded on the thread where the question from the member was placed and then where your reply was placed.....Will keep in mind the different forums.... Thanks.
[Asus ZenFone 3 Ultra Questions & Answers] Apo11on:
OK...Since like you pointed out yourself, you're a junior member, and appear to be a bit confused, and quite a bit confrontational for no good reason - I'll clarify a couple of things. First, my comment about thread hijacking was not directed at you. Look closer - I quoted a post of another member, VillaRegina. Here on XDA (and pretty much every other forum out there), when you quote someone it means you are replying to that particular person.

The only portion of my comment, that is actually addressed to you starts after [MENTION=6291804]Slbtrb79[/MENTION] - that's how you directly refer to somebody on XDA.

When I first brought up Xiaomi Mi Mix you said "I believe your post refers to the Mi Mix with the ceramic body and audio technologies you mention, but that phone will only be sold in China." - neither part of this statement of yours made any sense, but I let it slide then, because you appeared to be new and a bit confused. I expressly referred to Mi Mix by it's name, provided a link to the manufacturer site of that phone, so saying "I believe you post refers to..." makes no sense, because it implies doubt, as if there is a certain amount of ambiguity which device I'm talking about. Second part of that argument of yours, which states that phone will only be sold in China, and the following explanation why you didn't bring it up dont make sense, first because Xiaomi Mi Max you did recommend is also not a US phone, and second because you're acting defensive, as if someone has accused you of not mentioning Mi Mix. To react that way made no sense, because no one has accused you of anything and your feeling that you had to provide justification, why you didn't mention Mi Mix is irrational and misplaced. What happened here is very simple: An XDA member VillaRegina seemed to be interested in some phone recommendations. One XDA member (you) provided some recommendations, and then another XDA member (me) provided different recommendation, which he felt is newer and better. That's all there is to it. No need to get defensive, no need to be confused about comments, directed at another member.

I see that I caused a problem with my dumb questions... I posted a lot about the Mediapad X2 to learn how to set it up so maybe I am not a junior member...

[Asus ZenFone 3 Ultra Questions & Answers] Apo11on:
You haven't done much wrong and you have nothing to apologize for. Actions of other members are not your fault. It's OK to ask questions, as long as you follow 2 simple rules:

1. Do your due diligence before asking. Do an XDA, Google etc' search first - it's very likely you're not the first, and your question has already been asked & answered

2. Make sure to post in the right forum/thread. If your device doesn't have a forum on XDA - there is a general forum for Android, and Q&A threads.

[Droid Ultra Q&A, Help & Troubleshooting] lpisme:
Hey all,

For some time now, my camera has not been working...kinda. If I use the regular app or any third party camera app, it comes up as a black screen, freezes, and closes down. But then something weird happened.

I started playing Pokemon GO. On the bits where the camera is enabled (to throw Pokeballs), the camera works! Even more bizarre, if I open the camera app while Pokemon GO is running, it will work just fine! This applies to both the front and back camera, both of which had the issue I mentioned.

Only when the app is open though. When I close it and try to go back to the camera then no-go. I have done a reset on the phone, I have tried all kinds of third party apps, I have tried booting in safe mode. Nothing works except what I just mentioned.

Can anyone shed some light on what might be going on? I'd like to use the camera without opening Pokemon GO but I am OK with it for now since I can use my camera again, albeit in a convoluted way.

I was thinking about trying a custom kernel (insomuch as I can with a locked phone). Worth a shot?

Any help or suggestions would be greatly appreciated. Thanks!

Hardware Problem...
[Android General] NT79:
Thank you for the tutorial. I know nothing about flashing.

However, I could follow the instruction until 4. Flashing the: "G750-U10 to G750-T00" Firmware.

The problem is that after I had clicked the "Download" button, and connected my device, the error popped up BROM ERROR : S_SECURITY_SECURE_USB_DL_IMAGE_SIGN_HEADER_NOT_FOUND (6045).

Could you please help? Thank you.
[Android General] SeñorNeusAap:
That error means that your bootloader must be locked. For me, it was acting weird. They way you want to (try) to unlock the bootloader is as follows:

1. Install ADB drivers. I used a tool made by XDA user Snoop05 (http://xdaforums.com/showthread.php?p=48915118)

2. Connect your device to your pc

3. Open up a command promt from windows

4. type "adb" and check if it returns a big list of available commands (that you know for sure that adb is installed)

5. Type "fastboot" and check if it returns a big list, for the same reason

6. Now type "adb devices" and check if it gives your device, if not make sure you have correct usb drivers installed for the G750-U10, if not just install HiSuite from Huawei (It comes with the correct drivers), then disconnect your device and type "adb devices" again.

7. Now type "adb reboot-bootloader" and your phone will restart in fastboot mode.

8. Type "fastboot oem unlock" and follow the instructions on your phone screen (they are very small and hard to read).

If your bootloader is now unlocked, you should try to flash again. My phone gave an error at the step 9, but I still followed these 9 steps. So the error I got could also have been a visual programming error, or bug.

I hope this helps! Keep me up to date :)
[Android General] Iroh96:
Same error. I tried several times with "fastboot oem unlock" but it didn't work: err 0x7000. I could't find anything helpful on the internet.

The odd thing is when i typed "fastboot getinfo-bootloader" I got "(bootloader) unlocked".

I just wanted to be a pokemon trainer too :(
[Android General] SeñorNeusAap:
That was the excact same error I was getting. Also the same deal with the oem get-bootinfo thingy. Are you sure that while flashing you have unticked the "preloader" and the "usrdata" sectors? That is what did it for me honestly :)
[Android General] Iroh96:
I'm very sure, i tried locking ad re-unocking the bootloader but i get the same error
[Android General] SeñorNeusAap:
Alright, then skip step 3 and go to step 4. I might have screwed up the step orders (It's hard to remember in what order I did all the steps :P) if that works, i'll change the OP. I'm dorry if thats the case.
[Android General] Iroh96:
You mean flashing the G750-T00 fw and then the chinese one? So I have to reinstall the original fw? Cause currently I'm running the chinese
[Android General] SeñorNeusAap:
Yes, flash the g750-t00 one, and then the rom that you want if that worked. I think that I might have skipped that whole firmware downgrage rom :P
[Android General] NT79:
Thank you for answering :)

I tried what you had told me to do, but when I typed "fastboot oem unlock", the phone told me to use Volume Up/Down button. I used "Volume Up" button to unlock bootloader but it failed - err 0x7000 same as Iroh96, I guess. So I typed "fastboot getinfo-bootloader"; however, I got "waiting for device" instead of "(bootloader) unlocked". Then, I tried step 4 but it was still an error 6045. I don't know what to do next.

Why is it so hard to be a pokemon trainer? :(
