Hello to all
is almost three months that I'm struggling with an annoying problem
the tablet I lose the signal gsm, it appears the rod antenna and it does not work, sometimes it takes a few minutes sometimes hours
initially I thought it was problem of SIM, I replaced the SIM but the problem remained, always recurs every random and in different places
After all the tests I took the tablet into a service center if you are required a month, just access the tablet has presented the same problem
any of you have had these problems, I would avoid staying for another month without a tablet
Thanks to all
Francesco
Hi,
From past three days, signal is not showing up on the phone. And it only shows a red triangle with a white plus sign on it.(Emergency Calls Only)
I didnt do any changes to the phone, it just randomly started three days ago.
I am on Indian version of unlocked Motorola atrix 2 MB865.
I am on jellybean 4.1.2 for past many months. So I dont suspect the ROM.
I have tried using some other sims also.(It is NOT the problem of the Sim)
I usually get full signal at my place.
I have searched internet thoroughly and read almost all the threads related to this topic, but it didnt help me much.
Things I have tried till now.-->
- Swapped sims with many other phones.
- Installed the "Network" app and many other similar apps which was suggested in some other threads.
- Switched Flight mode on and off.
- Factory reset the phone.
- Kept it off for hours and then checked again.
- Prayed that it will get fixed soon
Q) Did you try turning it off and on again?
Ans) Yes..yes.. Many many times. Sometimes, after reboot it shows signal for 2-5 minutes, but I CANT make/receive any calls/sms(The call just drops two seconds after dialling)
PS:- I think that when I received the last call, I was listening music on my headset and I had received the call with the headset.
Thank You very much.

Baseband version is showing as 2012-0712 09:44 Off Blf LUD_EDISON_R1E_PATCH_36_120712_0920 ch1090280_M570_PC_CARD_RAINB
I have now found that it is due to very very poor reception.... For some reason, this phone's signal reception has drastically reduced.
I can get signal only if I go out, still the signal strength is shown at maximum -75dB and frequently dropping to -100dB. I was able to make one call and it dropped as soon as i entered inside the house.
(The same sim on other phones have full range even inside house)
What is the suggested solution?
Thanks

Seems to be a hardware issue then. Is your phone within warranty, by chance?
Nop it is not in warranty.

If you can't afford to help, then what's the point of this post?
Increasing post count I guess.
Might be a loose connection after a drop ?
Your best bet would be to dissamble the phone and assemble again. In the meantime check the connectors and others if they're in their place. There're good disassembly videos for atrix 2 in youtube.

K s h i t i j s, who is your network provider? EDIT: Just saw that you're on MTNL.
I have been having a similar problem for a similar length of time with my Atrix 2 and I'm on stock ICS. I got my sim replaced by Vodafone but the problem persisted so I asked the guy who originally sold it to me to get it checked out (warranty is long gone).
He mentioned that another customer of his with the same phone also developed the same problem around November or December 2013. Both that guy and I are on Vodafone, Mumbai.
In testing, his phone worked perfectly with an Airtel sim and mine worked perfectly with a borrowed IDEA sim. Both our sims work perfectly in other phones. Both were then sent to the official service centre but they essentially threw their hands up.
The coincidental timing of the problem for two (maybe three) phones of the same model leads one to think there must something with the network broadcasting? Could someone with better knowledge of the subject (mine is approximately nil) comment?
Hello.
I bought this phone about an week ago, and after two days i noticed that i couldn´t make or receive phone calls, after a litte bit of research i noticed that the phone only has network signal on 4G areas and when i try to switch to 3g or 2g it takes a lot of time (about 2 minutes) or most of the time it doesn't get any signal.
I´ve already done 2 factory resets , switched the sim card and i still cant make calls.
Is there any way to solve this?, because if i activate the warranty it will take a lot of time to get my phone back.

Seems like manufacturing defect. I guess you would have already tried network mode and automatic search.
I have a dual sim setup, one on Telstra and one on Vodafone. At random intervals and probably at least 5 or 6 times an hour both Sims will disconnect...the signal icons show no signal. After a few seconds the signal returns to full strength....I'm sure this has only started happening since upgrading to 10 but I can't swear to it.
Does anyone have any ideas?
Cheers
So I found the solution. My company has recently mandated work profiles and uses VMware MDM.. The dropping has been ever since I installed this. Uninstalled and got rid of the work profile and now it's working again....
This happened very often, when mobile signal is weak the phone will stuck in HDPSA (H/H+) with no internet and finally lose its entire signal, even later moved to a better signal area. I have missed a lot phone calls / messages when this happens, have 3 different brand new Note 20 ultra replaced by warranty all have this problem. Can confirm this is not network or SIM card related as when swap the SIM back to Note 10 plus it is just working fine as it should be (3 days while waiting for replacement using the same SIM living in the same area). Put the phone into flight mode and turn it back can solve the problem however the difficult thing is you won't know when this will happen and for the price tag, it seems it should be this kind of problem with it.
This issue seems also with S20 release too, for years the issue is still there, anyone have the same issue or can help?

Hi Thanks for the recommendation so dose that mean to use this tool to manually force the phone to stay on a certain type of band? (eg not using HSDPA?) . I was thinking this would be fully automatic as it is a basic function of a mobile phone
I've installed and will give it a try next time the signal is lost.

Yes you can force the phone to use a certain band, and yes the phone should be doing this automatically but you can use this as a workaround and maybe a future update will solve the problem for you
