Tmobile and Band 12 (700mhz)

Can anyone using this phone with Tmobile sim confirm that band 12 (700 mhz) is active on LTE. Specs says it's there but is it active now?

It's not activated yet. It will be in an OTA tho

Thanks, hopefully not long!

Can you manually turn things like band 12 on with tweaking firmware or root access? Even if you could, would that guarantee you could actually use whatever band you just turned on?

No its in the firmware and radio imgs. Maybe if someone is good at those hacks

im using phone now and there is no VOLTE on device....from what ive read, it wont be coming either.....smh @ tmo and motorola not gettin they minds right for this beautiful device...get great lte data speed where i live and work though. i dont think band 12 can be activated unless tmo sends the update...prolly gonna retirn the phone tomorrow because of this ....smh

Please link this "from what I've read" infomation because I know I have read at least 3 posts on the Motorola forum (and a couple of Moto rep tweets) where it will come in a future OTA.

Purchased US version but have WW ROM?

Hey all,
I picked mine up from BH Photo and the model on the box says it's ZE553KL-S625-3G32G-BK which should be the US version but my current firmware is WW_11.41.87.2_20170514.
Did they load the wrong firmware? Send the wrong phone? Or something else? I'm not getting amazing battery life on AT&T so I'm worried I'm missing some bands...

I got mine from Amazon and it's the same build number. I think we both have the WW version and I'm also on ATT but have really good battery life, so I'm not sure why yours is lacking.
You can see what basebands are offered by each version here:

Okay, cool. I guess I'm confused how some people are asking and verifying if a version of the phone is WW or US if even the US one comes with a WW rom.

Yeah honestly I'm not sure. I read somewhere that both versions have the WW and that B&H had the US one and Amazon sold the WW one, but since I think I have the same version as you that makes that even more confusing.

Hi everyone, I'm on the same boat, I got a Zenfon3zoom from Amazon USA and I'm using it in Mexico and currently working fine under VirginMobile with B2 for 4G.
I've not tested other SIMs to see if the other operators work under 4G BUT I've tested searching for other cellphone networks and AT&T which in Mexico works under B4 for LTE shows up, so I've come to the conclusion that my phone in fact is the US/BR version since that's the only one that supports B4.
Maybe you could do the same test?

I used the app "LTE discovery" on the play store. It supposedly tells you which band you're using on at the moment. It appears to have good reviews, and thats how I saw that I was on band 2 or 4 depending on where I was in the city.

.
Sorry I not good at explaining things,
Basically go to: "Settings->More->Cellular Networks->SIM1->Network operators->Search networks"
That will show all networks supported by the phone, after that I just search what bands those network operators work with in my city/county, since the phone can see them, it means those bands are supported by the phone.
My phone can see Mexico's AT&T 4G networks, AT&T 4G LTE in Mexico works with B4, since the ASUS website list BR/US the only version to support B4, my phone is BR/US version.

So I figured out a more definitive way to test which version you have (I have US/BR after all). When you go to fastboot mode it says it under RF_NAME. To do that hold volume down as the phone boots.

I just went through all the firmware on the Asus support page and they are all either for the WW or cn version. There is no update for any US version. So I'm thinking the WW and us version firmware is identical.
I'm also in need of Lte band 20 for when I'm in Europe 3 months of the year. I wonder if Asus could make adding Lte bands easy for all of us like the Samsung phones with a hidden menu so not everybody messes with it and bricks their phone.

So far the conclusion is that Amazon version is US (https://www.amazon.com/Zenfone-ZE55...Warranty/dp/B06XW6SJF8/ref=cm_cd_al_qh_dp_t)? I need band 4.

I purchased mine on Amazon and it is indeed US.

I have the US version. Didn't update to Nougat yet. Can anyone tell me if the battery performance, screen etc. is any better or worse after updating to nougat?
Also are there any easy ways to roll back to original marshmallow if we are not happy with nougat?

I've upgraded and haven't noticed a difference in battery life. There is no easy way to roll back your phone to marshmallow though, Following the post about converting from CN to WW rom would probably be the best way.

I purchased mine from offer up and I can't update mine the rom is WW but idk which variant I have?

H918 - signal strength cuts out and searches for network

I've just bought a used H918 (unlocked T-Mobile) and tested it and everything seemed fine. I'm in the UK. I tried to make another call this morning and it wouldn't connect. When I looked, the signal indicator showed zero bars and 2 little rotating arrows above. Eventually it would jump to 2 bars and then 5. I tried with a different sim and the same happened. I put it side by side with an LG G2 with the other sim (same carrier, iD mobile) and the G2 showed full signal with both sims while the V20 kept dancing around.
It's not rooted or modded and has just been updated to the latest security patch (still on Nougat)
I need to decide what to do - the seller will accept a return but the phone is mint and was great for what I paid. Is there likely to be a fix I can do or is it a hardware issue that's beyond my control? Time is of the essence as I need to let them know.

Thanks for letting me know, but that's terrible news! I looked into potential issues and thought it was only potential GPS or heavy battery drain. I guess it's not going to be any better with a Korean variant?

Caller ID and spam protection setting

Is anyone else noticing the caller ID and spam protection setting turning itself off?
it's very annoying anyone solved the problem?
just tried clearing the data for the hiya system app will update if this seems to clear the problem

Just noticed it after seeing your thread, mine was turned off as well. I remember turning it on couple of days ago. Perhaps it might be controlled by the carrier end ?

Yes, noticed it a while back and I have the same speculation that it's being turned off by carrier settings even though I bought the unbranded unlocked model. I'm on T-Mobile.

Same issue here as well. It was the same way on my s8 plus with the pie beta. Both are unlocked devices running on cricket. I've noticed it everytime after a restart. I think that's where the bug is at unfortunately.

Same

Lol just checked mine after reading this, and mine is off too. Mines bought direct from Vodafone UK . Wow I know I switched it on its one of the first things I set up.

I've noticed mine off, but additionally I haven't noticed it doing anything when I get a call. On the unlocked S9, it would provide basic caller info and possible spam warnings. Now I get nothing if the number is not in my contact list. I'm running a factory unlocked s10+ on Sprint. No Hiya installed.

Yup can confirm mine shut off itself after I turned it on during initial setup, unlocked galaxy s10+ on Verizon

Something I have noticed is that after turning it back on and receiving some calls from unknown callers it has remained turned on, usually the setting just turns back off a few times a day.

Is there anyway to enable this on tmobile branded s10+?
Or only on the U1 unlocked firmware?

I think T-Mobile disables this feature on their variant. You can get it by flashing the U1 firmware tho.

Nope, still happening to me on my unlocked...

I can confirm the March update fixed the problem for me. Exynos UK Vodafone.

And our unlocked Snapdragons are still the red headed stepchildren with no update.

The pop-up came some days ago but I didn't turn it on because of :
- if the call isn't from one of ùy contacts, it is masked or unknown, and I know what to do about the former.. not answering.
- As it is obviously a samsuing service, I don't see the point of putting myself more in the hands of a conglomerate than I'm already and I don't see how reliable might be the said service, considering that the official callers black list is a mess here in france (I let you decide for you guys in your respective countries).
My point is : are we SO busy, SO amateur, SO lazy and SO mobile enslaved to jump on every notification from our devices ?

can someone point out where this setting is? I searched for call, caller, and spam in settings to no avail.

Open the Phone App, tap on the 3 dots on the search bar and then open settings. If it isn't there then its disabled by your carrier if you have a carrier branded phone.

give the man a cigar, verizon calls it caller name ID, but the real head trip is that their customer service people typically don't know it exists until you explain it functions like the old landline automatic caller ID, it costs $2.99/mo, but i've had it literally ever since i bought the moto z and it still mostly worked on the s10+ to this day, i love having it too, people call at random i answer "hi steve, don't spam me again you prick" and hang up, dude calls back later freaked out i knew his name already, worth the $2.99 easy for the giggles.

Well, everyone is different. In my case I also prefer not to pick up when a number is blocked or the nr is not in my contact list. However, I regularly get calls from Dr's, hospitals or other people related to the care of my parents, so I like the opportunity to be able to distinguish one of those calls with that of a recruiter or some company that wants to sell me something.

Flash IN2020 to IN2025

Do we have a clear, step by step on how to do this? I've tried flashing the IN2025 firmware via local update but it still shows as In2020 with disabled camera.

Might want to back up your persist partition before you do that. May break it

Well yes, but I'm trying to get it to flash to IN2025. It's just not doing it.

Flashing software does not change the hardware. You're on an IN2020, and OOS will report as such even when you flash intl OOS.

So essentially, there's no way to get it to re-enable the IR camera.

Well, that thread was locked before there was a magisk link posted. The other guide is to either enter a debug mode or to use a GCam hack which unfortunately crashes a lot.

If the phone does not support your radio bands, changing the firmware to the unlocked Global FW won't enable them.
If your carriers radio bands are supported by the IN2020, you may need to add their band combos as per this guide:

He hasn't changed the hardware, he has changed code to trick the phone to get the photochrom filter back, this will not work on band's for 5G

i have a Photochrome option when i use my camera, does that mean that it's still in though.

Yes if the option is there you will have either a phone that isn't IN2020 or 21 or if you do you have one of those phones you aren't running the latest firmwar for that phone.

Where To Get This Model EDL Mode Firmware , One Plus 8 Pro China (IN2020)

My understanding of 5G support by these different phones is in the link here, https://drive.google.com/file/d/1mgz7Z6TADnXZgpCdCoLeRHX22wC_vLq8/view?usp=sharing . I am currently in the U.S. and a T-Mobile customer but planning to move to Europe one of these days. Though T-Mobile only supports the n71 band today (not supported by IN2020), it will be rolling out the n41 band (supported by IN2020) soon with the merger of Sprint. On the other hand, n78 (supported by IN2020) is quite common throughout Europe. With that said, the Chinese Model, IN2020, seems to be the best compromise if one travels extensively. It overlaps with the European bands over several different frequencies and one US band that I know of (n41).
Unless of course you are an AT&T customer, then IN2025 is the only way to go because they use n5. In this case, you won't get 5G coverage while you are traveling internationally (except on n41 in China) because the US 5G is just so different than overseas.
None of these models support mmWave, and these phones will become antiques first before mmWave is ubiquitous anyway. If even fingers can attenuate the mmWave signal, we are talking about at least several transmitters on every city block to make it practical! That said as of 2020, I wouldn't spend extra $150-200 USD for a phone that supports mmWave. Google's new Pixel 5 could have been $150 cheaper without it.
Other than the radio compatibility, I can't really think of a good reason to convert an IN2020 to IN2025. If I'm missing something, please enlighten me.
The method described by Whoareyou sounds very interesting. I may try that one of these days.

Here's my story.
I got my OP8pro in China, and once it's in my hand I flashed it from H2 OS to Oxygen OS. Through the past two years my model was showing as IN2020 with no issues until I saw a Beta version of Android 12 Oxygen OS. I flashed it and the model turned to IN2025...I googled the difference and that's how I get here.
