[Motorola Photon Q 4G LTE] Loader009:
I tried to figure out, if our Photon Q is supporting more LTE bands than 1900 MHz (#2 or/and #25).

-> http://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths

On some sites there are reports for having another band. (Have to search again, I think it was 850 MHz, #26 or 700 MHz, #12/#17/#29.)

I have also searched for supported frequencies for MSM8960.

I found some BlackBerry devices based on that SoC and 2 different versions of supported LTE bands.

One version (UK) supported 4 in europe used bands und the other version (US) supported 4 in US/Canada used bands.

I think that the Photon Q is like the BlackBerry US version and supports 4 LTE bands in US/Canada.

If you need a few sites, I will search again and show it to you.

The strange thing is, if I set to LTE only (via 4636) I can see all 4 carrier (germany).

We have 3 bands with LTE on it, but I can only get signal to max 2 of them.

Band 3, 7 and 20 (1800, 2600, 800 MHz).

The weird thing is, that on band #20 (800 MHz) only 3 carrier are active, so it has to be band #3 or #7.

Maybe I'm missinterpreting things and thats just a sideeffect of crossing bands of LTE US and UMTS Germany.

On stock ROM there was another "secret phone code" to see what the phone-part is doing. (From qualcomm I believe.)

I think I will test it some other day, to see which band is active.

At last, I was never been able to "login" or "register" into my carriers network within LTE.

Please discuss about that possibility, I really want to find out, which frequencies are supported by our phone on LTE.
[Motorola Photon Q 4G LTE] disablewong:
Dear Loader009,

Thanks for your information! I'm really impressed that you could actually search the carrier in 'LTE only from Germany!

Could you please share the version of ROM you are using?

And if possible, any screenshot? I really want it can be used in HK with LTE(1800, 2100 & 2600Mhz)

Also do you have more information about the secret phone code? I think it would be interesting

Actually, I noted that xt925 and xt905 are using the same chip MSM8960 with LTE usable in HK.

Is there anyone can locate the radio/baseband of their rom and port it for XT897?

I am willing to try it with my machine.

If this work, I think we could use this photon q all over the world!

Any idea?

Regards,

Vasco
[Motorola Photon Q 4G LTE] disablewong:
Of course, I was just blind guessing the hardware for xt926 and xt907 are using the same hardware.

If not, there should be one chip controlling the modem channel of the device to be replaced.

But WHICH ONE???

Any expert in this area can solve this question? I am a dummy for radio stuffs
[Motorola Photon Q 4G LTE] xLoveHateLegend:
This seems like it's getting pretty interesting.
[Motorola Photon Q 4G LTE] jhgfjhgf1:
Dear all,

I'm also very interested in this topic since I imported a Photon Q to Germany and was wondering if it's possible to use the local LTE 800/1800/2600 bands.

I think the first thing we have to find out is whether the hardware is capable of using other bands than the 1900 band listed on the Motorola website. As Loader009 states he could see LTE carriers which are known to use different bands I assume the hardware can do it. Otherwise the carriers wouldn't have been listed, right? Maybe someone from another country with different frequency bands can check and confirm that he can see those carriers as well?

Thus, the limitation to the 1900 band should be software-made and could be modified by a developer. I hope someone can participate at that point as I don't know much about coding...
[Motorola Photon Q 4G LTE] Loader009:
I'm using CM10.1.

I can't remember the secret phone code, I have to do research again.

This secret phone code only works on Stock ROM. (I stupidly deleted it, when it wasn't working on CM10 anymore.)

The one secret phone code I used to force "LTE only" was *#*#4636#*#*.

Please DON'T change the baseband (don't even tap on it).

This can do problems to you. (I had to use QPST to recover the supported frequencies.)

Also, developers (afaik) can't modify the modem firmware.

We also don't even know, which LTE bands the Photon Q is capable of. (Except 1900 MHz)
[Motorola Photon Q 4G LTE] Loader009:
I've got my 32GB SDCard back and will test it in the next few days out.

I hope I'll find that secret phone code, I'll also make a few screenshots.
[Motorola Photon Q 4G LTE] Loader009:
Got the code!

##33284# <- ##DEBUG#

It only works on stock afair!

I'll test tomorrow, it's about 3am now >.<
[Motorola Photon Q 4G LTE] Ronin2012:
I have read the "QU_SnapdragonS4_White_Paper_FNL_Rev6.pdf" and found there following entry:

-----------------------------------------------------------

• Industry’s first fully integrated 3G/4G world/multimode LTE Modem: <<<Supports all of the world’s leading 2G, 3G and 4G LTE standards>>>.

It also includes integrated support for multiple satellite position networks (GPS and GLONASS) as well as short range radios via Bluetooth,

WiFi, FM and NFC.

• Designed for speed, compatibility and power savings:

Snapdragon S4 Processor MSM8960 chipset includes the industry’s only complete platform that integrates all of the world’s leading 2G, 3G and 4G mobile broadband modem technologies on a single chip. This new integrated multimode modem is based on an advanced, programmable architecture that is performance, size and power optimized for the fastest combination of modems available for:

- LTE FDD/TDD (Cat3)

- 3G (DC-HSPA+ Cat 24)

- EV-DO Rev. B

- 1x Advanced

- TD-SCDMA

- GSM/GPRS/EDGE NFC.

Multimode/Multiband Means Worldwide Coverage.

• Support for multiple radio frequencies: Mobile broadband technologies are growing increasingly complex in their implementation. LTE is currently being implemented in over 40 diff erent radio frequency bands throughout the world. To complement its wide range of modem standards supported, Qualcomm has designed the Snapdragon S4 Processor MSM8960 CHIPSET platform to <<< address all commonly-used frequencies (from 700–2600 MHz) and bandwidths up to 20 MHz>>>, allowing its customers to address any mobile network opportunity whether the simplest single frequency implementation to the most extensive multi-frequency global mode, whether 4G, 3G or 2G.

-----------------------------------------------------------

Based on the document the chip can handle all LTE Standards, but it depends on his "advanced, programmable architecture"....as written there and how Motorola / Sprint implemented this, maybe they reduced LTE only to one Standard.

I don't have LTE in my area and so I cannot test this.
[Motorola Photon Q 4G LTE] Loader009:
That's possibly right.

Something else:

If I remember correctly, somewhere in this forum have been said that for CDMA the internal Sprint "ID"(?) is used.

Maybe that's also the reason why I cannot connect to LTE in my area.

The phone is trying to "login" with the Sprint ID and this of course won't work.

The ##DEBUG# menu wasn't helpfull. It shows frequencies for american standards and not for GSM/WCDMA.

Also the LTE menu is also not very helpfull, it doesn't show frequencies at all.
[Motorola Photon Q 4G LTE] jhgfjhgf1:
Any News on this topic?

Maybe one of the developers can give a statement?
[Motorola Photon Q 4G LTE] Loader009:
Yesterday I tested a LTE compatible SIM card.

My Bro has a Samsung Galaxy S4 with 4G/LTE in my area.

So I've put his SIM-Card into my Photon Q and set LTE only.

I had no luck, the Phone couldn't register into the network for this SIM.

I guess either it has the wrong frequencies or LTE is for inbuilt "SIM" (Sprint SIM?) only.
[Motorola Photon Q 4G LTE] Skrilax_CZ:
The latter. LTE is configured only for 1900 MHz which Sprint uses.
[Motorola Photon Q 4G LTE] zodiac12345:
LTE is configured only for Sprint's frequencies, however, it supports the United States frequencies of PCS blocks A-G. The G Block is Sprint's current LTE channel, and they may deploy it later on Blocks A through F, depending on if they own the spectrum in a given market. The reason you see EU networks when the phone is in LTE Only Mode is most likely because the Phone still sees GSM signals, but will only connect to LTE ones from those GSM signals. Likewise, in the US, if you force LTE Only and then search for networks, AT&T and T-Mobile US will come up as the GSM carriers the Photon Q sees, rather than the LTE signals it sees.

Setting the Photon to LTE Only will not do anything for LTE in the EU. I suspect that if another carrier in the EU uses the 1900 MHz for LTE, the Photon Q will have no issues connecting to LTE in Europe. But until that time, be happy with HSPA.
[Motorola Photon Q 4G LTE] jhgfjhgf1:
Can this configuration theoretically be changed / other frequencies be added?
[Motorola Photon Q 4G LTE] Skrilax_CZ:
Only if you break BP security.
[Motorola Photon Q 4G LTE] jhgfjhgf1:
Sorry, what's that?
[Motorola Photon Q 4G LTE] hfase:
IIRC The only place with 850mhz LTE available is the Chicago market and currently no phones at all support it. :crying:

Not only does your phone need to support it, your PRL and cell-site does too...

Just bought one from HK. Quality is not too bad for what you pay for. Came from a nexus s, so speed is definitely good. Not much lag. OS is almost stock with some essential mods which is cool. All china apps can be removed. Still trying out the battery.... it's okay, but could be better I believe.

Wifi is **** though. My 3 year old Nexus S wifi speed is 4 times faster if it's not next to the router.... something wrong with either radio or the engineering.... 3g is pretty darn fast.
[General Questions and Answers] drugo84:
I also noticed that the wifi if you are not very close to the router does not work well.

Do you think you can improve with modding?

If you have additional information to improve the device please tell me.

[General Questions and Answers] tssphysicsboi:
How long does your battery last? I found that the kernel isn't very good and that it seems to be eating quite a bit of power.... At least that's what android and battery indicator apps are telling me.

I haven't done much modding since I'm not that pro yet. This is completely different than a nexus... I'm rooted, but I'm do scared to even install twrp or cwm. Have you done it?

Rooting the phone was a very simple task just a click of a button.
[General Questions and Answers] drugo84:
the battery is giving me many problems _ I also think there is some problem nell'indicattore or in the kernel.

It lasts up to 10 hours (usually using it) but the sudden falls of up to 20% which makes it difficult to predict how current direrà and then the system unstable.

I'm not an experienced user q do not know the root await instructions from someone willing to take enlighten us.

Hello
[General Questions and Answers] tssphysicsboi:
I had problems with one of my batteries. I have changed to the second battery and the battery life was actually quite good.... Was able to last 30 or so hours with sleeping of course. But I had wifi running during sleep. I believe it's quite okay as long as the battery isn't defective.
[General Questions and Answers] tssphysicsboi:
I have finally found out what is saying that the kernel is using a lot of the battery. Try disabling the auto brightness from settings and you'll realize that the kernel will no longer be using a high amount of battery anymore. I believe star has made the refresh rate way too high, thus the major drainage comes from the sensor always bring active changing the brightness of the screen.

This has a lot got rid of the problem of the flickering screen when using SwiftKey for typing.

In terms of wifi, it's still pretty slow unless really close to be router.

Hi Integralac,

Just tried it out, but I am having problem even typing in the first command...

" wlan_cu -itiwlan0 -b"

the error says that wlan_cu not found... any help?

actually fix the problem for you? My phone is rooted already so I think I'll give it a try....

---------- Post added at 06:18 AM ---------- Previous post was at 05:46 AM ----------

For those of you with a battery issue with this phone (suddenly falling after ~ 40%) there is an app that will help with that. Yes, I've tried calibrating and all, but never works. After installing this app, it has seemed to fix the problem. It'll also help save a bit of juice. Give it a try:

[General Questions and Answers] integralac:
The problem is that there is now such file on the phone (wlan_cu). I was downloaded several files wlan_cu from the internet and there are differences in size. You can see here: ####dl. dro pbo xu serc onte nt . c om /u/788157 /wlan_cu.zip

Just retype #### with ht tp s:// *without spaces (stupid forum rules)

But when I tried to do step one I received some errors that I'm missing some more files (libraries) and it was dead end for me.

I didn't typed in these commands in the phone directly. I started ssh server on the phone and I tries everything through PC ssh client.

Anyway, I think that I have 3 issues on the phone.

1. uncalibrated wi-fi with constantly MAC address changing upon reboot-on/off swich

2. my Bluetooth does not remember the pear devices upon reboot-on/off swich

3. wrong battery mesuring

All in all I think that ROM which is currently in my phone is bad. My data is:

Android version: 4.2.1

Baseband version: MOLY.WR8.W1248.MD.WG.MP.V7.P1, 2013/04/10 00:41

Build number: S4 20130428-12004

What is your data?

I think that this phone is generic device which use several sellers. I find out some more names:

1. Pulid F13

2. (Star S4), sku46020.

I'll check it out right away thanks!

Installed with no problems, but the wifi speed is still quite slow if away from router (not fixed), but connection is better than before . . . I believe it maybe a hardware issue then.

My screen had the problem of going no backlight if in auto brightness, will try the new rom to see if it's fixed.
[General Questions and Answers] integralac:
Besides those WiFi rapidly decreasing of speed when you're going away from the router I didn't noticed any other problems at all.

It is much more stable version.

Correct, much smoother for sure. However auto brightness is still draining battery as it was earlier. The battery reading still has a bit of problems.

Issue when charging

Hello again everyone.

Would like to report and give some feedback now that the phone has arrived. Using ROM 2013.06.04-182644 there are absolutely no problems with WiFi (although it could be better) or battery, all working well and very smooth. BUT I want to ask if anyone else has had this very strange, weird, scary issue!

When the phone is charging, when I touch the screen or the touch buttons at the bottom or just "touch" around the phone, it goes crazy! It enters applications on its own, exits them, does all sorts of random things! This is only when the phone is charging and if I touch it.

Has anyone had this issue or read somewhere others experiencing it?

How to improve GPS and Wi-Fi reception

Dear fellows sorry for my bad English,

I was bothered with poor GPS and Wi-Fi reception like all of you so I decided to open the phone and see where is the problem.

On the motherboard for both antennas there are contacts for ground and hot-end.

The problem is that a factory antennas are constructed as self-adhesive foil on which are printed antenna lines and they are

actually making short circuit.

It is necessary, on the bottom of plastic you removed when you opened the phone, right below original antenna to stick the some

ground surface about 10mm wide.

I used self-adhesive aluminum foil. You must do so that the factory antenna make contact with the hot-end only and not with ground

contact from the motherboard.

When you open the phone and the screen is upside down, the battery compartment is under the motherboard, and on the left you can

see the GPS contacts and on the right Wi-Fi. For GPS upper contact (further from the battery) is ground, and for Wi-Fi bottom (near

the battery).

Isolate parts of factory antenna (that one for ground contact) and tape over the aluminum foil that will have a hole at the part

where the hot-end have to touch the factory-antenna. Finally you have to tape the duct tape over the aluminum foil or isolate with

something, so when you close the phone that ground foil will not touches something inside.

For GPS you should set all A-GPS and EPO settings but I will not explain it here because you can fined it on Internet.

For more better Wi-Fi signal or let say even better data flow, especially when you are away from the router, you should attach over

the factory antenna, on the outside, L-shaped aluminum foil.

Unstable work of GPS and Wi-Fi was caused because contacts were shorted and there is no ground surface.

If someone is interested in matter I suggest to look on wiki dipole antenna.

My final results are:

- 10 sec to lock GPS signal and SNR is around 33 dB, accuracy 3m = no more problems with GPS software I had

- at point away from router where I had 0,001 Mbps I now have 30+ Mbps down/upload

Problem WIFI and GPS Fix

Hello again. I modified the wifi and gps antenna. I still do not know how to catch fixa. The wifi signal is still weak.

I made measurements of the meter. On the motherboard for wifi I have shorted pins. while I'm on pins GPS break.

Please help attach pictures modification.
[General Questions and Answers] integralac:
In first pic there is some wires solder to MB on left side near power button? I don't know what is it?

On second pic I see that you have aluminum foil for both antennas. It is wrong. For GPS use original antenna just cut it as I posted.

For Wi-Fi you need to use original antenna, but to put from bottom side aluminum foil and to connect it only to the "-" contact on MB. You need to have hole on foil in order to "+" contact from MB can touch original antenna. After that you can add self adhesive aluminum foil on exterior side in "L" shape but not to touch shiny part around camera.

For third pic I don't have comments.
