Hi there
I recently bought an Alcatel 991d and replaced it a couple of times due to signal loss and sim freezing (no internet, sms, and calls on either the sims). I passed to a Samsung Y duos which is more stable although it seems to still have some signal problem (when this signals is lost it does not come back although a good coverage area is reached, 3g icon disappear and no internet surfing is allowed, sims freezing (rare). With the Alcatel other people experiences serious problems expecially under poor coverage areas and hypothesized the problem could be related to the continuous jumping from 3g to 2g cells. Actually my Samsung y duos goes nice and smooth when I only use the 2g network. Do you think that countinous jumping form 3g to 2g can cause problem to android smartphone in general? Can you think to a solution for this?
thanks a lot!
my friend have similar problems on Gigabyte dual sim phone (I forget model name). didn't found solution yet
my xperia l's network reception is weak and while speaking in the phone, it get heated up and call also get cancel sometimes. Is it a hardware issue???
I just got a new xperia z5 and I'm using it on att but my phone signal is always showing zero bars.
I get data but incoming calls sometimes don't go through or go through after 2-3 rings.
The signal shows bars when I make outgoing calls but then disappears quickly thereafter. I thought it was maybe WiFi calling enabled but I don't even see that option anywhere in my phone and this happens when WiFi is off too.
This is a very strange phenomenon and can't find any answers anywhere. There is also a small circle with a line going through it on the notification bar, not sure what that is.
Does anybody know what's wrong ?
Small circle with line indicates "do not disturb" mode is active. Its under sound or notification settings, can't remember which. For signal status, check APN. Also, is your IMEI for this phone the Z5 one or an old AT&T phone? If AT&T has your IMEI for the Z5 it will register on their system as an old phone since they don't have Z5 in portfolio. I had to give them an old IMEI off a LTE device from AT&T because it was showing as a P series phone in the system and I was only getting 3G, no LTE.
Just noticed the small circle was for sounds. Thanks
I am getting LTE which is weird because it just not showing any bars on top but the lte works.
No one else has issues with their signal bar on their xperia z5?
This is really strange and can't figure out what's wrong with it.
No issues with the bars per say but definitely issues toggling networks, especially with 3G prefered mode. When 3G prefered selected I only get mobile data when H+ icon shows next to the bars. 3G, 2G and H don't work! The phone sometime takes up to 10-30 seconds to toggle to H+ and be connected. This drives me nuts! Do you guys experience this as well? Today I got no signal at all (no bars, nothing) for two hours.
Stamina is off and I have proper signal.
SFR France btw.
Try to toggle LTE off.
This sounds like an issue I had with a data only SIM in Japan with my S6, except no 2G network was the cause I think, not sure what would cause it on AT&T.

It's strange because I show full bars when I make an outgoing call or right before someone calls me, all the bars fill up. But it takes 2-3 rings on their side for it to ring on my phone.
And after the call it goes back to zero bars. But I still have the lte sign there.
Is there a way to update the gsm radio?
Same issue here (Z5 on ATT). I get one bar consistently when the phone is idle with the bars filling up when making calls, sending texts, etc., but I do get full LTE speeds and haven't noticed any other problems... I did look at my account, and the Z5 does show up as an "unknown device".
I tried changing APNs from "Attnextgenphone" to just "ATT Phone" but it didn't make a difference...

I am glad I am not the only one with this issue. At home I get one bar with wifi off and with wifi connected I get zero bars until a call is made or received.
I am located in NYC and have the 32.0.A.6.152 rom and the baseband is 8994-FAAAANAZQ-00029-16

Exactly the same here (FW and baseband). I'm in CO and I do sometimes get full bars outdoors, but it happens randomly... It's almost for sure a problem on ATTs end considering that they don't even recognize the device on their website.

Is there a newer baseband that we can upgrade to that will fix this signal issue?
Or de we have to wait till the marshmallow upgrade comes out.

Hi, it's a high probability that you are seeing bar fluctuations as you suggest because your phone is actually changing bands during this time, because the cell tower pushing your call etc doesn't have the signal strength to push LTE.
As for the OP if his LTE/4G shows higher bars as soon as he is using the internet this is a different issue, and strange maybe faulty hardware.
I would recommend you all go somewhere where you know there is good coverage, even with another phone if possible and see if you still have the same issue.

Mate I am not sure the phone suffers from signal issues, I have had most of the Z series phones, all have the exact same signal strengths for me at various locations, and the phone has better coverage than other manufacturers as well, when I compare to other friends in super low coverage areas
Hey @bigneeker,
Just wondering if the MM update has fixed your signal issue.
For me it hasn't, but if it did for you then it might be a region issue (mine was Singapore, but I flashed the MM update for Germany).

It didnt for me
I noticed it too. Sony xperia z5. I use the quick LTE toggle and when LTE is on, all my bars are greyed out, but when LTE is off and I'm on H+ and 3G then all my bars are lit up.

Same here. Also, whenever I lose signal or inexplicably switch to Edge, toggling the LTE switch off and on seems to fix the issue.
I compared the specs of the Z5 and the specific bands/frequencies AT&T uses, and the problem might be the frequency that they use on Band 12... I don't know.
I don't know about European carriers, but since T-Mobile uses a different band for its LTE, then that might explain why this issue is not that well-covered in the US (though I can't confirm that).

I'm in Ireland and my signal suddenly went from H+ to Edge then no service. I haven't came across another person with the same issue, my signal goes between H+ and no service most of the time is no service. Tried 5 different firmware and custom rom nothing changed
hello dear friend
currnetly my z3 lost signal and third party cant hear my voice however i hearing him/her well, actually i tried all ways like sim card changing, network testing or changing from gsm to LTE and finally i found out the my mobile has some malfunction
So the only way i think is about software downgrading
Is there anyway to fix this problem, sometime my antenna lost completely however my frined z3 is fully ok
please help me about this issue :crying::crying:
stock marshmallow 6.0.1
I have a similar problem. Everyones hears me right but my network signal is much more poor since Marshmallow update. Suddenly, when i'm calling someone the signal of both sims gets lost and the call gets cutted. After that the data conection desapears and i need to restart the system to get data conection again.
very disapointing.
yeah i have low bars and patchy voice quality after mm in my flat.
Same issue on D6603. Maybe a restore with pc companion is necessary
Guys,
I bought an Sony Xperia 5 mark ii Docomo (SO-52A) from a near by shop..it's showing less network signal (no of range bar) compared to other Indian smartphones..does flashing a global rom resolve this problem?.or any other solution for this?
There are many discussions about the way Sony phones show the signal strength at the top bar, which is much more sensitive than other phones. This means that the icon bars change a lot (maybe too much?).
But the reality is that the signal is strong just like in other phones and you are good.
So the question is: Do you **really ** have signal loss ?
Bro sometimes it shoes even no signal..while others are geting 1-2 range bars
Yes, but the question is if you really cannot make reliable calls or use data in a speedy manner.
As I mentioned, many users saw the icon signal strength fluctuation but with no impact at all in reality.
I'm not saying it should be that way, but it **may** be a false problem.
I can't share a similar experience because I have an European 5 II and I live on that region.
No problems with signal reliability at all.
