D5803 AT&T LTE sticking on 1700mhz when 700mhz is available - Xperia Z3 Compact Q&A, Help & Troubleshooting

Loving my Z3c so far, but I'm having one weird issue.
My APN settings are correct and I'm getting LTE, but I noticed that I was only getting two bars at home and my dBm was super high compared to my other phones (I normally get full bars with every AT&T phone at home). I rebooted the phone and it came back at full bars, with a really low dBm. Today, I went to work and after I came home, it was down to two bars again with a high dBm. I toggled mobile data off and on and it returned to full bars and low dBm.
Here's what I THINK is happening: I believe that at home, it gets on the 700mhZ LTE network and all is fine, but at work, it gets on 1700. Then it gets stuck on 1700mhz and stays that way until I toggle the connection off/on. It still gets LTE and decent speeds, but the dBm is high and the bars are low. I don't have any other phones that do this.
Does anyone know if there's a way to disable certain bands. On the LG G3, you can turn off LTE bands that you don't want in the phone menu. I'm wondering if there's a way to disable 1700 so this won't happen. Also wondering if anyone else on AT&T is experiencing this. I'm stock, not rooted.
Thanks!

X1 Band does not switch

i'm having a problem with the band not switch when its low on signal. for example i will get the H and when it drops down to 1 or no bars it doesn't switch to E. also some times when the reception is around 2 or 1 and its on H, i would drop calls or can't call out at all. for some reason i've noticed that the reception issue happenes a lot and i would have to change the band to GSM and 850, 1900, then it would stay on E.
anyone has this problem or know a fix?

I was about to suggest you flash a different radio, but then I noticed that you're on AT&T. It's just your network being crap.
I believe the network sets the rules on handing your cellphone signal over to another tower. Only thing you can do is tell your phone to force EDGE or HSPA.
yea when ever i have no signal i have to force it and the best i can get is edge. but this wasn't an issue before? could it be a hardware issue?
Depends on carrier too. I have such issues sometimes.
But X1 also tries to keep 3G/HSDPA as much as possible...
YEAH I BEEN GETTING THE SAME PROBLEMS WITH MY XPERIA, I HATE IT BECAUSE IT IS LIKE IM BEING LIMITED OFF GOOD RECEPTION SIGNAL. SOMETIMES I CANT MAKE CALLS AT ALL. cOULD AT&T BE DOING THIS TO ALL CELLPHONES LIKE MY X1, SINCE THEY WANTED TO CHARGE ME 30 DOLLARS A MONTH FOR UNLIMITED INTERNET,SO I COULD GET 3G SPEED, SOMETHING I DIDNT HAVE BEFORE, BUT I STAYED WITH MY REGULAR INTERNET SPEED, AND NOW I EVEN GET FASTER INTERNET SPEED THAN MY BROTHERS AT&T HTC fUZE 3G PHONE.
Well just a FYI, but AT&Ts network isn't the great in San Franciso anyway.

(Q)HTC one low signal bars UK EE/Orange

i recently unlocked, rooted and s-off my htc one, on stock i used to get around 5/4 signal bars and now i only get two/three.
im currently running trickdroid 7.5 rom 4.2.2.
so im looking for a radio which would work for orange/EE in the UK.
please can someone help, or point me into the right direction
this is the one for the 4.2.2 firmware

Are you sure that it is not the same level? Don't be fooled by the bar looking different, remember that it might show 2 bars of LTE but that could still be better than 5 bars of H+ (as an example).
So if you used to get 5 bars of 3G but your now getting 2 bars of H or H+ then you are better off even though its less bars.
Please do not take this as me treating you as if you are stupid, I am not, I have come across a lot of people recently who thought the same, and it turned out to just be a different type of signal.
fixed
okk i just flashed 1.29.401.12 Radio and it's back to normal.

thanks for the input but!
i never said i was using my data connection,
Same principle applies even with data off.

So if I have 5 bars when set to "GSM" only but 2-3 when set to "GSM/CDMA" .. that's as good?
I'm being serious btw, I normally set mine to just GSM as I seemed to have more signal but if there isn't any point then I won't bother lol ..I'm in the UK btw and on a network that doesn't support LTE (I think)

You can confirm the 'type' of signal you are getting at any time in the menu > settings > about part of the phone.
Your phone will automatically switch to whatever the best signal is available at any time, you don't really need to change your GSM/WCDMA settings, unless you really want to force it away from 3G connections (again this does not mean you have to have data turned on).
Cool, I'm not too fussed about what data type it uses as I rarely have data turned on, I just naturally assumed that by switching it from GSM'CDMA Auto to just GSM, meant that I'd have better reception, being that the signal bars went from 2/5 to 5/5 ... You learn something new everyday lol
EDIT: I checked my signal, and I mean my reception, not the data connection type, when switched between GSM/WCDMA Auto and GSM Only and there is a huge difference. I found this guide:
dB Signal - A basic guide
-50 to -60 (very strong, near a cell tower)
-60 to -70 (extremely good, rare)
-80 to -85 (normal downtown)
-90 to -95 (getting on the weak side)
-95 to -98 (weak, dropping calls)
-98 to -100 (bad, hard to stay connected)
-100+ (basically no usable signal)
When I set my phone to GSM Only I hover around -70, which is good, when I switch to GSM/WCDMA Auto it is a different story. I know it changes and finds the best signal, which I might add drains more battery on an already power hungry beast, but I was hovering at -100 which is terrible and often calls were dropping or people were saying it was engaged when infact I hadn't used it.
It's clear to me that in my case, GSM Only is the far better option if I actually want to use my phone to make calls ... Data speeds I'm not arsed about so EDGE is just fine with me.

[Q] Access to more Network Mode options? XT1053

I saw a few screenshots of people's Moto X's from sprint with a bunch of options under Network Mode. I have the XT1053 (TMO unlocked, on ATT network) and the only options I see are "Auto" and "2G."
I browsed around and found that there's an LTE OnOff app, but I'm just wondering if there's a way I can get those options for 3G on my device's Network Mode option list?
The reason why I even care is because for some reason at my workplace, I can't seem to get any data through LTE. My signal will display 3 bars of LTE, but it absolutely does not work. While it will turn off LTE and just say 4G since it's on auto, I find that a majority of my day, it WON'T switch. It stays on 4G LTE 99% of the time and does not function at all. When I walk outside the building, LTE works perfectly fine. Would I be right to assume that the auto mode is literally on borderline between switching, so it never establishes a stable connection?
I guess it brings me to the question, is the Auto mode inefficient / will I have to live with manually turning off LTE every time I get to work? :/

3 bars of LTE is an excellent signal. With 1 bar of signal I can still get 15mbps down from my provider. If your phone is detecting such a strong received signal it won't be switching back to HSPA on its own. For some reason the building you're in may block the phones transmitted signal more then it blocks the signal from the cell site. I am guessing you're on band 4 LTE which has quite the frequency difference between uplink and downlink. Your only option(assuming the phone or cell site isn't defective) is to manually switch to WCDMA with a third party app such as the "LTE setting" app in the Play store. Or unlock your bootloader and flash firmware from another provider that has more options. I know the Rogers Canada firmware has an LTE on/off option, it also has a 2G only option. Sadly Rogers has not yet approved the release of 4.4 (kitkat).

That makes a lot more sense to me now. So basically the "Auto" mode only considers my reception and not transmittance strength, so it never saw a need to switch me off LTE. I am almost sure it is not my phone because I started experiencing a signal loss issue with my S3 a few days ago. I doubt it's the cell site because as soon as I step out of the building, LTE works with no problems.
I did ended up using LTE OnOff to force CDMA and I can actually do stuff now. I went and did a speedtest ...
Ping: 114 ms
Down: 4.06 Mbps
Up: 0.77 Mbps
I guess with the lack of options, I have yet another reason to roll up the sleeves and get my hands dirty. Haven't touched ABD since I had a samsung captivate!
Thank you

Force HSPA+ instead of 4G?

Does anyone know how to force the note 4 to use HSPA+ instead of 4G?
The reason why i ask is because in areas where i cannot get 4GLTE the note 4 goes into 4G and its basically unusable (~1mbps maybe, most of the time i cannot even perform a speed test) eventhough the 4G is with 5 bars. In the same exact area HSPA+ gets very good speeds of 6mbp+
To test this, i forced 4G on my note 4 at my house and got a 1mbps speed test. Before upgrading to the note 4 from t-mobile i had an old note 2 from verizon running H+ getting 6mbps+ at my home.
Update: i really think the note 4 or the modem is causing the issue. Testing again my my house. When i first force the 4G connection the speed test are horrible. (< 1 mbps). After some time it seems idling in 4G it seems i got pushed into H+ reframed?(but still 4g icon) and getting consistance 6mbps.
I also noticed that the note 4 drops LTE to 4G at 2 bars or so when LTE speeds is definitely present and running at 20mbps
Hspa+ shows as 4g. If you go to other network settings where the apn is you can select lte,wcdma, options. In remote areas my 4g speed is better than my lte . The lingo is kinda weird so every carrier has different definitions of 4g. Hspa+ is technically 3.5g lol.
The app Advanced Signal Status let's you choose your network type.
Install it from play store and lock it to what you want. Try phone calls and SMS for the modes you try because some modes will be data only.
I noticed this today at home. I forced it to WCDMA mode only, it took like 10 mins for it to eventually show "4G" at my home office. The signal and download speed were terrible when forced into WCDMA hspa mode+ (4G) . In the same room and home my Note 3 would get a very good signal this time last year when I used the Note 3.
Perhaps T mobile has done something to the cell site here? Or The Note 4 isnt working as it should?
Ive had the same issue. So i work in one city and live in another. So when i get to work my data is slooooow. I force it to 4g and after a while back to lte. Speeds are fine. Same thing happens when i get home. Tmo told me to just restart my phone but that doesnt always work
Same situation with me. LTE tower doesn't reach my room but I got 10mbps in my living room....and my room I get less than 1mbps and goes to lte to 4g often with very slow speeds. I even have a LTE booster which doesn't really help much with speed. Without the lte booster I get almost 0 signal in my room
I used to have same problem during lte upgrade in my area. On lte around 8+ up and down while on 4g speds were 15-20 down and less than 2 up. Ping times were longer on 4g. After upgrade I no longer need to switch between lte and 4g

But is T Mobile removing their 4G HSPA wcdma towers? I used to get a very good db signal in my office, now -115db at best for 4G in same location but band 4 700Mhz is now present? Any relationship between these ...
See the below screen shot. On that menu you can pick the non LTE function and force H+. You can also switch back to LTE.

Thanks I had already figured out how to.force a specific data connection , hence why that thread I posted was asking what the default option is, since I didn't write it down.
But back on subject, 4G next to non existent now at home after 700mhz band 12 availability.

What is UMTS? I never get Hspa+
I've found that my data is ridiculously slow (I'm talking edge speeds) when I turn WiFi off, even when I am in an area that gets a strong LTE signal. I feel like my device does not automatically connect to the best available tower; rather, it seems to try to latch on to whatever tower it was connected to before I connected to WiFi. Toggling "mobile data" off then on again seems to reconnect my device to the closer/better tower and the speed improves drastically. (It's possible that toggling airplane mode or network modes will do the same thing). When you are in an area that has poor LTE, you might consider keeping it off. Change the selection from “LTE/WCDMA/GSM” to just “WCDMA/GSM” and you'll be on the slower HSPA+ network (though, I believe it still shows the 4G icon). You can always change it back when you are in a better area.
4G is back up and running in my home location. Must have been temp disabled when they rolled out 700mhz band 12 LTE in my area.

5.1 giving better radio signal?

I have noticed that with 5.1 while I normally got just 1-2 bars at home of signal I am now getting 3-4 and better speeds. At first I thought I was now getting Band 12(tmobile) but LTE Discovery says that I'm still on Band 4.
Anyone else seeing this?

When I am in a very weak signal area, I am definitely getting a better LTE signal. But voice/calling (GSM) is worse on AT&T. Where I could make a call previously, on a very weak signal, now I get nothing.
Just finished flashing 5.1 and setting it up - and I'm definitely getting higher single indicators for LTE now (T-mobile Band 4) - I rarely used to get 1 bar in my house, but now it constantly shows 2-3 bars. Whether the coverage is actually improved is yet to be determined...
5.1 is definitely giving me a better radio signal in my house as I usually only had 0 to 1 bars. Now i'm getting 3 to 4 bars and my messages are sending without without delay now. I'm on AT&t.

Not for me!

I'm getting better "signal" on 5.1 (more bars) However my lte speeds are horrible now Was 15-20 mbps and now its consistently 3-5 mbps on Tmobile.
Indicators can be changed to always look good. Actual signal probably didn't change.

This.
Its showing 3-4 bars of LTE in my house now, where before lucky to have 1.
But dbms are literally the same for me at least.
At work, inside thick concrete walls, inside of more thick concrete walls...I used to be able to keep a solid 4G signal. Now it barely keeps connected, and when it does it never goes off of EDGE. I'm on TMO btw.
I think I'll be switching back to the last radio. Not impressed with this new one from the 5.1 update.
Another thought is the transition from LTE to HSPA might be improved. I wasn't able to make a phone call in my basement at my desk. Now after the 5.1 update I was able to call and hold a conversation in the same spot.

The 47E radio is the best radio so far (for me at least).
