Loses 4G Signal After call - Sony Xperia Z Ultra

My XZU loses LTE signal after every call comes in and remains in 3G for long time before re-connecting to the LTE signal again.
Is there anyway to rectify this?? Its very annoying because 3G is extremely slow on the device.

you could add some settings into the build.prop to enable 4g to kick in sooner.
Sorry I'm not sure what they are...
But by default 4G is set to óff' when making calls to save battery.
The following enables 4G all the time. But that would reduce battery life. Probably only 3-5% depending on how often you are on a call.
"lteOnGsmDevice=1""
The next settings will increase the download /upload speeds
ro.ril.hsxpa=3
ro.ril.gprsclass=12
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=20
ro.ril.hsupa.category=7
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
If youre not sure how to make these changes to your build.prop just post another question here... I.. or someone will help you out.

Thanks....so any kind soul can assist to find where the build.prop file is?

sorry thought you may have known...
O.K. are you rooted??
yes - lets continue
no - lets stop. You wont be able to access this file unless you have root access
I'll assume you are rooted.
a) Do a backup. Sometimes (not often) modifying your build.prop file causes boot issues)
b) Use a file manager and navigate to your root directory. just go back as far as you can. There will be about 5-10 folders, and a file called 'build.prop'
That's the file you want.

Nope I am not rooted. Anyway to do so without roothing? I am a simple user.

No unfortunately...
There is no way to access these root files unless you are rooted.
This is the reason why users want root access. To change some default settings and make a few tweaks.

[mod]Boosting Signal Strength (hspa/gprs)

If anyone has anymore info on the ro.ril. properties, I would greatly appreciate it.
It would also be great if every shared the script they use with which network.
You'll need a rooted Streak and Root Explorer.
Add/edit these entries to "/system/build.prop" (you must mount to r/w and open with Text Editor). Make sure that these are not already in your build.prop, if they are, then just edit the values.
ro.ril.hsxpa=2 (higher values are invalid until proven otherwise)
[0=UMTS] [1=HSPDA only] [2=HSPDA & HSUPA]
ro.ril.gprsclass=10 (Class 10 to save battery)
The Streak supports Class 12 GPRS, set to 12 to increase EDGE speed
ro.ril.hep=1 (no info available, no change when turned off)
ro.ril.enable.dtm=1
Enable "dual transfer mode" on EDGE networks; requires different GPRS class setting. Only set this to 1 if your network allows simultaneous transfer of Circuit switched (CS) voice and Packet switched (PS) data over the same radio channel (ARFCN).
ro.ril.hsdpa.category=8 (Cat 8 is the Streak's max)
ro.ril.hsupa.category=6 (Cat 6 is the Streak's max)
ro.ril.enable.a53=1 (enable increased ciphering on HSDPA/HSUPA)
ro.ril.enable.3g.prefix=1 (Adds the 3G prefix e.g. Optus 3G, etc.)
All Carries have their own specific settings they should use.
As Im using Optus Prepaid in Australia these are the setting I use. Lots of experimenting went into these and my 3G works better than ever. Best SpeedTest I've got was D2.98/U1.52 48ms ping on 4 bars, average is about D2.5/U1.0 80ms.
Code:
ro.ril.enable.dtm=0
ro.ril.gprsclass=10
ro.ril.hep=0
ro.ril.enable.3g.prefix=1
ro.ril.hsdpa.category=8
ro.ril.hsupa.category=6
ro.ril.hsxpa=2
ro.ril.enable.a53=1

This will not increase the power of your antenna or increase radiation. All this does is choose the best profiles for EDGE/HSDPA/HSUPA. Its proven to increase speed and connection strength.
Wow! This is cool - am definitely going to give this a shot

No offense, but you sound like a novice at Android development. Where did you hear about this build.prop tweak? Do you work for a cell tower contractor? Seriously I'm not trying to offend you, just confused.

It sounds make sense, modifying the RIL parameter. However I found those 3 lines a little bit .... maybe the first two lines are unnecessary due to our device is not HTC? And for all those lines, i think there should be no blank spaces between characters. I might be wrong though
dw I did my research and testing b4 I posted and every entry has some effect on signal strength
I posted em ages ago, they are in steves streakmod rom
the bitmask ones won't make a difference, as they aren't valid for the streak..
If you're seeing a difference its placebo I'm afraid
Aw snap... good lookin out. No offense to the dude that posted the tweak.

Hey, I'm on SD 1.7.0 and I don't see them in my build.props? Should they be in there or did Steve already include it somewhere else in the ROM and therefore no need for me to add it to the build.prop?
Thank you.
When I saw this on DJ_Steve's StreakDroid thread, I tried it. It broke my data connection. I had no WiFi and no 3g. I deleted the edits, and everything worked fine after that.
I might go back and try it with the double - reboot, though.
they arent in 170, they dont work for everyone..
in earlier roms they were in /etc/local.prop
but I guess we'll have a new thread with someone proclaiming they found local.prop works for prop settings as well
So, to try these out, put them in build.prop, do a double reboot and if it didn't break anything, then keep them? Else remove them and double reboot again?
Worked on my US unlocked streak on 1.7.0. Don't know if it really changed anything. Speeds are about the same and signal strength looks the same. Wifi still works fine.
UPDATE: Spoke too soon wifi broke. Connects to my router but no data. Uninstalling.

Cell data connection stalling - anyone else experiencing issues?

Hi!
Is anyone else experiencing problems with the mobile data connection on this phone? It frequently stops working. Being in an area with excellent HSPA+ coverage, this can't be a signal issue.
The phone will suddenly stop loading anything, while displaying "3G" and an active upload indicator in the notification area. No internet usage is possible in these situations.
The only remedy: Cycling "data network mode" off/on. The phone will then immediately pick up HSPA+ again, working as intended.
My previous phone (Nexus One), which I used pretty much identically and at the same places as my Galaxy S2, did not experience these stalling issues. Is this a general (firmware) problem, or should I possibly look into getting a replacement unit?
I also have this problem. My SGS2 is on O2 (UK), got the phone from P4U.
Exactly the same problem, connected through H+ with good signal, suddenly the phone will switch to 3G and I will lose my connection, this can last for minutes unless I toggle data on/off. I am on KE7, but had this problem with KE2 as well.
It sounds similar to a problem mentioned in other threads, but this is the exact problem that I am facing.
I am also considering replacing the phone (if it is a phone issue, and not a firmware issue)
Happens to me also. Very annoying
Sent from my GT-I9100 using Tapatalk
Same problem here, but i also have problem with communicating via phone. Every time it starts in home, usually morning. I cant recieve any phonecalls or sms, also i cannot call or send sms. Need to reboot, signal is -113dB and i cannot choose plane -mode, it doesnt go there. Also i cannot select operator manually. Reboot is needed every time. This scenario has been over 3-4 mornings and i have owned SGS2 about 1,5 weeks now.

It's good to know I'm not the only one experiencing intermittent connection issues - as this appears to be a firmware problem, I will wait for Samsungs next few releases to solve the problem. If the bug won't go away I might get a replacement unit.
In any case, please report back - if someone got his phone replaced due to this issue, did it fix it? Any other possible solutions?
I've spoken about this issue, the 3g itself doesn't want to work.
I've tried uskr's fix and it seemed to have worked. Also root needed.
The fix involves editing /system/build.prop
adding to the bottom.

ro.ril.hsdpa.category=28

Same problem with my phone
Just to let u know guys i'm facing the same issue with this phone. My data connection disappears completely bringing up a circle sign. I also lose the ability to make or receive the call. I sometimes get calls going to voicemail with full reception, when this happens I can't browse either. I am debating whether to replace the handset as I have about 4 days left to get a replacement. I bought the handset from carphone warehouse. It is a sim-free unbounded handset running the latest KE7 firmware. Any help would be appreciated as i am absolutely in love with this handset. By the way could u tell me if anyone is experiencing jagged lines while scrolling in the browser.
That's something new.
Try factory reset.

hello iznee,
so how did you disable fastdormancy ?
i tried the hidden menu *#*#9900#*#* but it didn't work.
or did you do uskr method posted about how to disable fast dormancy ?
what about the method of editing the system.prob ?
which one of them?
please clarify
and did that solved your problem about switching from 2g to 3g ?
regards
It's not really a 2g/3g problem, more 3g/HSDPA and up problem.
And there "could" be two fixes, one I mentioned above (editing build.prop) lets call it data fix.
And the other requires deleting or editing the actual fast dormancy file as explained here
http://forum.xda-developers.com/showthread.php?t=1086599
Both are actually uskr's fixes. I did the data fix, which worked, but to make sure, I also deleted dormancy file.

[Q] No0b question to Atrix (EDGE network)

I'm new to this phone coming from the (facetiously said) jailbroken "God Phone" 3g. I had the option in that phone to switch from 3g to EDGE with a softswitch via SBSettings. I used this quite frequently as 3g coverage in my house is 1 bar and dropped calls. Is there a way to manually switch the Atrix to the EDGE network. I can't figure out the way to do that on this phone. I'm running 1.8.3 jail...errr...rooted with Gingerblur (if any of that makes a difference). I've done searched but I'm not doing it properly I guess so I'm finally asking. Thanx much

Seems ATT and Motorola don't want us doing that because it's disabled. Every other android I've had has had this ability. And it really annoys me because 3g sucks at my home and office.
I spent an hour on the phone with ATT over this. All I accomplished was wasting my time.
you can unlock that option, go to system\etc\motorola\com.android.phone
open the defaults.xml and change the
<boolean value="false" name="network_select_menu"/> from false to true.
reboot device
you should be able to manually change 2/3g than. I have it working on my att atrix with gingerblur 3.1, however im not on an att network, it still should work for you tho

also did it under /system/etc/motorola/com.android.phone

this didn't work for me until I deleted the backup files created by root explorer though. For some reason it was defaulting back to the original files. After I deleted the .bak files (in the data folder) it worked.
It doesn't seem to make a difference I've noticed. (Keep in mind I'm new at this) but I'm pretty sure my icon should change from H to E when I switch to the 2g network (options in network select are 2g, 3g and auto) Am I thinking correctly here? Or does Gingerblur override the icon?

[Q] Having some issues with aggressive wifi to cellular handover

My issue is that I am constantly stepping outside, out of reach of my modem, and I'll have to turn my Wi-Fi off or my phone will stay connected to the the incredibly weak wifi signal.
So, I tried turning the dev option for "aggressive wifi to cellular handover" on thinking this would help and allow me to just leave wifi turned on while stepping outside and have it switch over to data without my assistance. And it worked, for the most part (it still held on to wifi signals *I* would deem too slow, but not often), BUT whenever I reboot the option in dev settings un-ticks so I have to go back in and turn the setting back on.
My question is, is there a way to prevent the aggressive wifi to handover from turning off on reboots, or is there another option I could try that may even be more aggressive?
Thank you in advance!

I have the same problem, discovered the same solution, and have run into the same issue with no persistence after reboot! I'm googling now for a solution because going into developer options every reboot is incredibly damaging to the smoothness of the user experience I've worked so hard to customize.
Whether I find a solution or not I'll post in this thread again to let you know. If the latter is the result I will personally either write a tasker script, init.d script, or if nesseceary an Xposed module depending on factors I've yet to research. Can you Beta test for me if it comes to that? Maybe it's as simple as editing build.prop, I don't know yet, but I wanted to make this post ASAP so that you know you aren't alone on this and someone capable is working on the issue. For a developer like myself tapping menus every boot is unacceptable! Hopefully there is already a fix out there in the wild and I won't have to do any work.
P.S. Don't forget to also enable cellular radio always active for fast network switching at the price of some battery life. It's a few options below aggressive handover in Developer Options and thank jolly the setting is sticky unlike it's counterpart. Also, sorry for the poor turnout on your thread. I figured there'd be 100 posts by now, but at least you got my attention.
Edit 1: "setprop persist.{i-dont-know-yet}" in terminal emulator may do the trick. Checking for variables for the setting we want now. Hopefully they exist!
Edit 2: :laugh: I FOUND EVERYTHING I NEED FOR A FIX!!! However, an Xposed module will be required. I need some sleep but I should have something by tomorrow night. In case any other developers are reading this, here is the information required to make things work the way Iwe want them to:
http://android.stackexchange.com/qu...-cellular-handover-option-in-developer-settin
https://android.googlesource.com/pl...ndroid/settings/DevelopmentSettings.java#1061
Edit 3: Now that I know how this setting actually works together with wifi_watchdog (see source code WifiWatchdogService.java) I think I may have changed my mind regarding how to go about solving the root problem at hand (network switching) which this setting really does a "hack" job of taking care of. The developer that made it decided on a arbitrary, static number to be used for decreasing the connected WiFi AP's RSSI value (thereby making handover more "aggressive") instead of exposing any kind of grainular control to the user. So yes I could easily make the developer options setting stick but a much better approach would be to hook the method android.net.wifi.WifiManager with an Xposed module and implement additional logic to the network switching. The great thing about this method is there is the possibility for adding additional checks besides just periodically pinging the current primary dns server and monitoring the delay and timeout of the result. I also know for a fact modding the framework persists after reboot which is afterall all we originally wanted to have. The second or alternative route would be to edit the secure settings database using SQLite. The pro of this method is it is guranteed to be compatible with nearly ANY rom, won't break anything after an update, and doesn't use resources like an Xposed module. The con is that you are limited to the variables built into android, can't implement any new logic, and the worst is that I'm not even sure the modified tables would even persist after a reboot (or network state change for that matter) which if true would defeat the original purpose of this expedition. I'll make a fourth edit to this post after I've thought about and considered how to best proceede to reaching the goal of having a solution to our problem. :victory:

First of all, thank you so very much for looking into this!
I'm sorry for not responding sooner, but I had honestly lost hope of finding a solution to this issue mainly because I am not a developer myself and haven't the foggiest how to get started with it on Android
But when I opened my notifications and saw a response to this post (!) I got *extremely* excited, and as I read through your post, my excitement intensified to great happiness!
I can't express my gratitude, but I would be more than happy to help with anything that I can!
Any news on this?
Has anyone found a solution?
Had anyone found a solution that doesn't require root access?
Can we expect that fourth update any time soon? Any solution without xposed?
I'm following this thread in the event that someone finds a non-rooted solution. The Galaxy S7 really cannot be rooted without a serious performance hit (and yes I've gone through the two or three best/popular lag-fix solutions) but it works best in stock :-/

[SOLVED] Fulmics 7.0 hidden menu caused phone to lose cell/text connectivity

I really need some assistance ASAP on this one, folks. My phone/text is not working at all ever since I did the following stupidly today.
I tried to see if there was an option to get 2G/3G/4G working on the VS985 on 7.0. Guess I shouldn't have been so curious.
The only real steps I took to see was going to: Settings>Fulmics Tweaks>Advanced>Hidden Menu>Modem Protocol>Changed to Automatic..........now I have NO talk/text. Only 4G LTE data. Does anyone know what I'm referring to here? How do I get back to the original settings which worked fine!?
There must be a way out of this mess.
EDIT: there is! seemingly random combo led me to a solution.
Under the phone settings for mobile network - network mode: select CDMA+LTE/EVDO, and under the access point names: use VZWINTERNET. Make sure both of those are also the same in the hidden menu as well as selecting AUTO under Modem Protocol. That seemed to fix it for me.
Mods can close this one up.

Glad you got it figured out, do you have consistent 4g Data with Fulmics?

So far, so good. I haven't been to any areas with 3G coverage, but I hope to have that working as well now. I'm traveling halfway around the US this week, so it should make for a good test. Also installed Greenify - does voodoo magic for the battery life.

Thanks! If the combo above doesn't work, you can also try auto under the hidden menu frequency, and auto (or global) in the phone APN settings if LTE/CDMA don't give you a good signal or only give you data but not voice. For some reason the phone APN settings may look different depending on what you have previously selected or when you reboot. The access point should always be VZWINTERNET and you should not change any of those values in either the hidden menu or the phone network menu.
Once you get it figured out, you should not have any further issues or need to tweak these values unless traveling internationally. If that is the case, check the LTE bands carefully 1st and adjust frequency 2nd.
I'd be extremely cautious about changing any of these values. If you make any mistakes, recovering can be a slow process as these are system level changes that will impact the phone - no matter what version of android, rom or nandroid backups you had previously - cannot override these changes. Also, screenshots won't help because the changes in the hidden menu aren't reflected in the UI.
