It sounds like you have a different issue. Have you tried checking what your signal is in the service menu using *#0011#?

Here in Italy very bad signal with TIM also with 3g. Where my Iphone and Note 4 get full signal only 2 bars on my GS6. What the hell Samsung always release buggy phone!!!:)
[Galaxy S6 Q&A, Help & Troubleshooting] duckstardeluxe:
I forgot to mention that I was running the Lite version of the stock rom found here on XDA. The service code don't work on that rom, which made me downgrade to my backup of the stock rom.

I'm getting RSRP:-98 RSRQ:-6 RSSI:-71
[Galaxy S6 Q&A, Help & Troubleshooting] Japultra:
That matches your M8.
[Galaxy S6 Q&A, Help & Troubleshooting] duckstardeluxe:
Yes but the S6 continusly downgrades to 3G, even Edge. OpenSignal states that I have 4 g for 30% of the time the last 24 hours, everything else worse - like 35% 3G the rest lower. Faulty unit?

Possibly not, my Galaxy s6 service menu shows the same signal as my S4 but the S6 will drop to 3G while the 4G signal is still good, the S4 will only drop the signal when it gets bad.
[Galaxy S6 Q&A, Help & Troubleshooting] duckstardeluxe:
It's a dealbreaker for me. I'll demand a refund from Telia where I bought the device. Their network is the best 4G network in Denmark, and on my M8 or any other 4G device we have in the family, we can use the handsets anywhere inside the house, including the cellar. I've out my SIM card back in the M8 and will do a day with Open Signal installed and document the problem with the S6. A Samsung problem maybe, but I have no real interest in being a customer at Telia without proper 4G.

Just did a Speedtest with the S6 and then the M8 sitting at the same spot inside the house. 50-70 ms roundtrip and max 20 mbit download and 12 mbit upload on the S6. 15 ms. RTT, 46 mbit download and 27 mbit download with the M8.

Bummer.
[Galaxy S6 Q&A, Help & Troubleshooting] Japultra:
Something strange happened this morning. I am sitting in my office and was getting an H+ signal, so I turned airplane mode on and then off. It registered onto H+ again and then switched to LTE, but this time, I could actually see the correct signal dBm showing. Then a couple of minutes later, it switches back to -113. Someone in another thread said that he couldn't use certain apps due to this signal indicator being wrong. I wonder if it affects battery life at all - if some internal app thinks it can't get a signal and continues trying, thus resulting in worse battery life.
[Galaxy S6 Q&A, Help & Troubleshooting] Japultra:
Why don't you just ask them for another unit?
[Galaxy S6 Q&A, Help & Troubleshooting] duckstardeluxe:
I've spoken to both Samsung Denmark and Telia today. Samsung told me a story about the device being capabel of Cat 5/6 LTE and the implementation of Cat 3/4 which is currently the highest available here, might be with worse signal reception than if the chipset was only Cat4, like the HTC One M8. I think that this is really a terrible way of disregarding my statements and not listening to my points and observations.

Nevertheless I think that the real problem is, that the radio/modem in the S6 (taken the -113 dBm 0 ASU static value into consideration) thinks it need to prioritize 3G reception over less strong LTE in my area. Because right now I'm on H+ which the signal indicator in the status section saids have -75 dB, 20 ASU (4 bars in the top of the screen). In the service menu on LTE it saids -85 to -100 dBm which on my M8 is sufficient to stay on LTE.

I personally think the developers need to look into the code of the firmware/base/modem to implement a more robust interpretation of the signal strenght. I'll give it another go tomorrow but are hoping other than me contacts Samsung to tell the story also.

Telia thinks I'm right in my observations but could not really say that they have a way to adress it with Samsung. Other Cat 5/6 capable handsets are doing just fine exactly where I'm located.

If I'm right there is a hope that Samsung could release a new software, and the problem isn't unable to be solved (hardware related).
[Galaxy S6 Q&A, Help & Troubleshooting] Japultra:
I turned off LTE today and found that I got about 55% more SoT with my first 10% of my battery. I've tried for days to get more than 30 minutes of SoT before I reach 90% but nothing helped. I even tried it in a completely dark room so that my screen would be at the dimmest setting. The most I could get was 27 minutes at 90%. After I turned off LTE, I was using the phone in a bright room and got 42 minutes of SoT at 90%. Of course, it's just one test to get to 42 minutes, but a 55% increase is still significant. I think something is wrong with the way this phone handles LTE.
[Galaxy S6 Q&A, Help & Troubleshooting] duckstardeluxe:
I'm getting comparable results in regards to battery usage on LTE. Actually the phone works best with LTE disabled and forced WCDMA because the phone doens't change between 3G/H+ and LTE all the time :(
[Galaxy S6 Q&A, Help & Troubleshooting] Japultra:
You're getting about 40 minutes of SoT with the first 10% of use on LTE? This has not been possible for me on LTE.
[Galaxy S6 Q&A, Help & Troubleshooting] duckstardeluxe:
No no! Comparable to your experience. Sorry for my unprecise english ;)
[Galaxy S6 Q&A, Help & Troubleshooting] Japultra:
No worries! So you see a dramatic increase in SoT when on 3G vs. LTE as well?
[Galaxy S6 Q&A, Help & Troubleshooting] duckstardeluxe:
Si seniõr. I've just set the static 3G setting, doing a full charge (nice to know that the fast charge at least are working) and will report back in regards to SoT tomorrow.
[Galaxy S6 Q&A, Help & Troubleshooting] Japultra:
Looking forward to it! I am doing the same test myself as well and will report back also.

S4 (left) vs S6 (right) LTE signal strength:

http://i.imgur.com/PBKBrbc.png

Same network, same cell tower. The signal is always worse on the S6, disappointing.
[Galaxy S6 Q&A, Help & Troubleshooting] duckstardeluxe:
I found the battery life somewhat better on 3G only. Got around 50-60 minuttes more SoT.

In comparison to my all-metal M8 the S6 is just a LTE dissapointment especially taken into consideration that Samsung went over to use FPSB antennas according to http://www.androidheadlines.com/201...-system-ensure-galaxy-s6-stays-connected.html

At some point I get the same dBm on my M8 around the house as the S6, but the S6 more agressivly is selecting the more strong 3G+ signal than the M8 does. I think that it could be optimized with a new baseband. I'd really prefer that it stays on 4G because even with low signal I get like 20-30 ms. RTT and 30-60 mbit download. Also the shift from 4G to 3G and back uses more battery as well worsening the responsetimes.

Check my attactments. Screenshots taken exactly the same location with a few minutes between them.
[Galaxy S6 Q&A, Help & Troubleshooting] Japultra:
I've found having the phone on 3G helps with SoT as well. I got 2h5m with 71% battery left. Never had that before. I'm going to leave it on 3g for a few more days to test and then revert back to LTE to see if there really is a difference. It sucks that the radio on the S6 is not so great. Hopefully an update to the radio will help?
[Galaxy S6 Q&A, Help & Troubleshooting] duckstardeluxe:
Considering that the S6 isn't that far away from the M8, compared in the *#0011# menu, I think that the thing I mentioned about the device flucturating between 3G and LTE, I think that the baseband/radio could be optimized yes, but how do we adress it to Samsung?

The Samsung Denmark wasn't really interested in the issue, given the fact that they told me a story that shouldn't be true for at top-spec device like the S6.
[Galaxy S6 Q&A, Help & Troubleshooting] flycap:
Hey guys,

I got the same issue. Changing a "weak" 4G signal (which should not be considered weak) to 2G/3G . I have the same reception with my old Z3 Compact. Also around -105 to -110 [MENTION=313982]home[/MENTION]

I did some speedtests while being constant at around -110dbm. 20-30 mbit/s in a moving train. Even whooping 50-80 mbit/s [MENTION=313982]home[/MENTION]. Mhhh :confused:

Here is something interesting: ww w.lte-anbieter.info/technik/rsrq.php (german website)

There you can find some formulas, explanation and how you handle RSRP, RSSI. You need them to calculate the RSRQ.

The RSRQ is a calculated proportion, a scaled value to judge the reception: RSRQ [Watt] = N × RSRP [Watt] / RSSI [Watt]

N = number of resource blocks (depending on channel bandwith)

RSRQ in dB:

RSRQ [dBm] = 10 x LOG (RB [dBm] x 10^(RSRP [dBm] / 10) / 10^(RSSI [dBm] / 10))

RSRQ[db] can be split in grades:

-3 dB (very good)

-4 … -5 dB (good)

-6 … -8 dB (average)

-9 … -11 dB (pass)

-12 … -15 dB (insufficient)

-16 … -20 dB (fail)

So, in my case I still have a good connection DESPITE the -110 RSRP.. I think this is the flaw. Samsung needs to take the RSSI more into account.
[Galaxy S6 Q&A, Help & Troubleshooting] Japultra:
Mine fluctuates from -7 to -12. Would this be a reason why my battery drains while the phone is idle?
[Galaxy S6 Q&A, Help & Troubleshooting] phositadc:
Was this issue ever solved? Or did we determine if it affects everybody, or everybody in a certain region?

I'm using a G920i on AT&T in the U.S. If I do *#0011#, the RSRP gives an accurate signal reading. However, in Settings -> About Device -> Status, it ALWAYS shows "-113 dBm 0 asu" for signal strength. It just seems to be stuck on that. Like I said, *#0011# will show say, -85, -90, -95, whatever it happens to be, and it will fluctuated as I move around, as expected. The signal strength icon in the status bar will even fluctuate from 0 bars to 4 bars depending on where I am. But the "signal strength" in the Status menu will always read "-113 dBm 0 asu" no matter what I do.

Thoughts?
[Galaxy S6 Q&A, Help & Troubleshooting] mupet0000:
Yeah the service menu you can access from the dialer does show you the correct signal. But because for whatever reason the software isn't reporting the correct signal to android, apps like network signal info can't read your signal and the Android settings can't read it either.

Hi Everyone,

I am having an issue since last one month. Researched a lot but nothing helped me.

I tried to flash my xperia m2 dual (D2302) with a custom rom (MIUI V5, from ROMs section). I got the devices booted but when I realized lots of bugs in the ROM, I planned to switch back to stock ROM. I had flashed stock ROM couple of times earlier and so I follow the flash instructions again. I then realized the device is not booting in flashmode. Whenever I am connecting the device while switched off with holding the volume down button, A green led flashes and goes off. The flashtool says

Device connected with USB debugging off.

For 2011 line devices, make sure you are not in MTP mode.

I tried a lot but couldn't resolve the problem. Then I found CM11 nightly build. With that ROM I am using my device but it also has two major issues.

1) Sudden reboots (while chatting or while playing games)

2) No audio after using device for an hour or so after reboot. Reboot solves the problem for an hour but audio goes off again after one or one and half hours.

I want to go back to stock ROM. But unable to do so because of no flash mode.

For information:

1) I am using 64Bit windows 8.1 (I had flashed my xperia d2302 with this machine a couple of times before I flashed MIUI V2)

2) Drivers are properly installed, USB cable changed but not luck

I request everyone with the android development knowledge, please help me out. I am a newbie in this area and so don't know much. Please let me know how can I resolve the flashmode problem or can I revert to stock ROM using a way other than flashmode.

Or if you can tell me how can I fix the CM11 sudden reboot and no audio issues.

Please help me out. Please
[Sony Xperia M2] MrMaddTraxx:
The way to get in to flashmode is to make sure your phone is turned OFF , then you just have to connect your phone to a USB while holding volume down.

If you can't get it right this way, you could always try to flash trough fastboot, first of all go to your device information, where you can find your Android version etc. ... tap the build number for like 5-6 times , so the developer options become visible in the options.

Then in the developer option , turn ADB debugging on, connect your device with your computer.

Make sure you got the adb drivers installed and fastboot drivers also for your device.

Whenever your computer connects trough adb with your phone, you gotta allow the connection by allowing it on your phone. (There will be a pop-up screen).

Then you gotta make sure you got Android SDK installed, there will be a map called SDK, open it and then open the platform-tools map.

Move your kernel, recovery, and system images you want to install into this map too. ( Take one which is able to boot in Flashmode)

Then you gotta open up a command window. My path to the map is C:\SDK\Platform-tools, to get to the map you use the cd command, like this:

cd C:\SDK\platform-tools

then first of all make sure you got a backup of all your images etc. just in case....

in the command window type,

adb reboot fastboot

then these ones (all seperatly):

fastboot flash system system.img

fastboot flash boot boot.img

fastboot flash recovery recovery.img

After it is done succesfull you can type

fastboot reboot

You can try to be quick and allready press the volume down button to boot in flashmode.

Otherwise you gotta turn off your phone and try it again.

Hope to hear it works....
[Sony Xperia M2] markandeyp:
Xperia devices use FTF files for flashing. I don't have the stock boot.img and I am unable to get it.

I extracted the FTF but I got lots of sin files. I don't know how can I create boot.img from these.

Do you have any idea about it? Or if you have boot.img for Xperia D2302, please post me link for the same.

Thanks for the reply.
[Sony Xperia M2] Dzepar:
You don't have to extract anything, load whole ftf in Flashtool and leve unchecked Kernel (if that's what you want to flash) you'll flash only Kernel.

[Sony Xperia M2] Dzepar:
What's the problem? What Windows you use? Does your phone get recognized by pc(do you have all drivers instaled)? Do you have PC companion installed?

If you do, there is power off button by the sim card, press it then try to connect usb while holding volume down.

Try to repair your phone with PC companion. Then see if the problem is solved.

Good Luck! :)

Xperia M2 D2303 on K.K. 4.4.4
[Sony Xperia M2] markandeyp:
Yes. The phone is being detected by PC. I am able to get into fastboot mode but not in flash mode.

Pc Companion is installed. I am using windows 8 64 bit. Drivers are installed properly. I tried repairing the phone with pc companion but it is not detecting the phone while repairing.

May be the boot partition is corrupted. What recovery are you using? If you are using cwm then can you send me the boot.img from the stock rom cwm backup?

This may solve my problem.
[Sony Xperia M2] Dzepar:
I'm using This recovery and i have D2303, but i fi it help you here is my boot.img.

I think you have problem with flashmode drivers or your usb cable. I had problem with stock Sony's usb cabele now i'm using 10cm cable from Nokia that i had :)

Good Luck.

It's useful when driving and the phone's in a dash mount. Nothing like trying to get a fingerprint unlock while driving. With smart lock I tap the power button and swipe the screen all without looking at it. Also at work I wear gloves so I can't scan my thumb, again swiping is easier there.
