[Q] Can any genius solve my problem

HI, I am using Micromax canvas 4 from last 5 months. From last 3 months I am facing coverage issue in my home town. I am using Airtel network. The cell doesn't catch good range in my home only. Also many times calls get dropped. But when I tried same sim in other cell, it catches good network and calls to didn't get drop. Same is the issue with GPRS. GPRS too didn't connect quickly and transfer data very slowly but other devices don't give these problems with same sim. I had complained to Airtel and their engineer didn't find any problem in their network. Very interesting is that when I move outside my town, the same cell canvas 4 doesn't give any problem. It works perfectly. And please note other network doesn't give any error in my home town. I asked about this thing to one of the mobile expert about this, he told me that Airtel works on 1800mhz frequency and so canvas 4 might b not catching good range in that frequency. Can anyone help me to solve the issue?

I thought I will get the help here but no one genius replied to my query. I m very upset.

I have never heard such a problem before. I am also a Canvas 4 airtel user but i dint face any issue.
maybe you have not turned your 3G service OFF ( by default 3G service is ON on one of the SIM)
1. Goto settings>
2.wireless and networks> more
3.mobile networks>3G service >OFF
This generally occurs when you are not in a 3G circle or you may have not subscribed to the 3G services.
(Don't forget to press thanks if it solved your problem)
else use a vodafone sim in the other slot.

Bro if u will go by my advice just flash stock v14, I also had same problem solved it by flashing v14 @anupdada

@ashutosh. I m not a beginner my friend. Actually there is no problem in 3g mode. Only in 2g there is a problem. I found that if I am nearer to the tower the is no problem as such. It doesn't catch good net work if tower is at far distance.
@Alok brother how to do it. Hope I don't need to root for that. It's under warranty that's y. Pls provide me stock rom.

Which version are u on? U can check it under settings >>about phone and see the custom build version

@alok singh It's S9111B_MP_F2F3F5F8_B1_IN_MMX_14_FLASHER_USER

Brother I think no one genius here to solve our problem.

Do one thing, select ur network manually, select Airtel 3g if u have 3g plan activated else select Airtel 2g, see if this solves ur problem @anupdada @rahul110

it maybe a hardware problem or your service provider in a particular area. Do you face the same problem with other sim cards too? other than airtel? Maybe there are more number of airtel users in that area and less TDMA slots available. But i am not sure still you can try using a different sim card.
Or you can try flashing the stock rom once again. But it will wipe your data so dont forget to take backup of your phone memory or app memory. http://www.skyneel.com/2014/02/Micromax-A210-Canvas-4-get-new-update-Stock-Rom-V2.html

I have the same problem! You could solve it?

1. This may be obvious but you do have the sim in sim one?
2. Go to settings / more / cellular networks ends make sure you don't have 2g only selected.

Just update to 2.19.40.22 fw update..it has 3G stability and 3G works fine after this update..if you have older version this problem will persist ..

Same problem in my ASUS ZenFone 2 laser 550kl model finally said that customer care service executors better to check in authorised asus customer service centres the problem may occured due software issue...

Still facing this issue on Airtel Network in India at many locations. The network switches between 3G, H and H+ and hardly pages open up. Also, there are call drops when network switches from 4G to 3G/2G and 3G to 2G.

[Question] How to enable 4G+

Hello, I moved from zui to Pixel Experience on february. On that time I didn't have the option to enable 4g+ on zui yet. Is there a way to enable it being on a custom rom, without wiping or reflashing anything?
Thank you

Usually the phone switches between 4G+ and 4G depending on the area. Carriers make their networks interlaced so that the internet connection doesn't drop whenever 4G+ does not work. So it's nothing unusual to see 4G sometimes at the status bar.

You don't have to do anything to enable 4G+, if your location supports intra band CA your phone will automatically latch to 4G+
If you still want to forcibly enable 4G+ then
https://forum.xda-developers.com/lenovo-zuk-z2/how-to/enable-carrier-aggregation-lenovo-zuk-t3702194

How to enable 4G+
4G+ / LTE+ also known as CA isn't only a device related feature. Yes off course the device/rom has to have support for the same but its ultimately on your Career to support & offer this feature. So first thing to ensure the service is available under your Network Service Provider and its available in your locality also
ZUI 2.5 (Indian) having baseband 1.76 do support this feature. I have personally seen it working with stock ZUI or with non treble ROM running over this baseband. So if you are with that baseband of higher (like baseband 1.70 from Chinese ZUI 3.5), your phone probably ready for the feature.
Career plays the ultimate role here, so make sure to test with a SIM Card from a friend or relative to check for 4G+/LTE+ on different network. For me, Jio 4G regularly switch to 4G+/LTE+ in my location Kolkata. But mind you not all cell tower or location shows this icon. So some places offer regular 4G.
Last but not the least, here in my place, that's India, with or without 4G+/LTE+, network speeds are more or less comparable to a proper 3G at max. Often I see 4G+ icon and network speeds are like old 2G age !!

Moto g5 no 3g and no 2g- no calls. Only 4g HELP!

hello, friends. Specially those who are worried about the so many problems with signal moto g5 users face. Im here asking for help. i have a moto g5 (cedric) i was working almost fine with oreo stock. i say almost because some times when i lost signal it didnt recover like any other phone woud, i had to reboot. now from almost a week ago i had lost signal and now i only have 4g. no 3G and no 2G, so no voice calls going out nor incoming ones. i ve done hard resets, flashing stock 7.0 and going back to stock 8.1 and nothing. on saw 3g for a little moment coming back to oreo. i also flashed carbon rom wich is android 9.0 to see if a custom rom helped but it didnt. i only have internet now and sms. and this is very frustrating. ive checked persist folder and everything is correct there. i have my imei right, this phone is like new but not being able to call is like not having a phone at all. also why i have to reboot to recover missing signal? is just a pain. this moto phones are really problematic when it comes to Signal management.
things to consider too: im currently on stock oreo, just rooted to be able to check if persist folder was correct and to backup efs folder. also my operator uses 900mhz band as 2g and 3g wich is an european frecuency not common in latin america. maybe that has something to do with problems im facing. the rom has cedric_latam_cust as the baseband. can anyone help me find one frome europe? im wondering if flashing one from there could help. the weird thing is that it was working before with that baseband.
so many people losing 4g, i could be glad if that was my case and had 2g and 3g only with full internet and calling capabilities.
im sorry i know it is a little bit too much information. but i really need the help

You could get your country firmware from here.
https://mirrors.lolinet.com/firmware/moto/cedric/official/
And don't flash older version firmwares as it will brick your device.and you should try a different sim card in your device to know if there is a problem in sim card or the device.

Thank you friend. I was able to download and flash an euro rom. Just to find that the baseband was not changed after flashing it. I even tried erasing modem and reloading non_hlos but I still have latam baseband on settings.

Not at all. I'm still having 4g only. As I mentioned before, in status it is still showing the same baseband that was in first place. One from Latin America. But I was trying to get it changed to an Europe one by fishing a new rom from O2. But it didn't change.

Maybe you should try pixel experience ROM(pie) or retin firmware as I was on retin and I got many choices such as Europe, United States, some frequency. Maybe you should try pixel experience first as it going fix network problem many times, then you can try retin firmware.

In my country we have 3 mobile operators. Movistar won't work (don't know why), the other works perfect on my phone. Mine from a week ago only work 4g. This afternoon it worked 3g but when I rebooted it stopped. Only 4g again. So no calls.
The first screenshot is with 3g and no signal
The other 2 is when rebooted having activated 4g

I came from a couple of phonesin last 2 months, htc one, Galaxy S3, Galaxy j2 pro, and iPhone 5s just right before this moto and neverb had any problem. Right now I used my sim card with my wife's iPhone 4s and my mom's 5c, even an old Galaxy spica and all worked with it. I'm frustrated

This g5 worked for a week with 3g and 2g normally. But a week ago started this nightmare

It seems the problem is API as you are getting 4g but no calls then it could probably API only, try editing the API or creating a new one. You can get the API configuration from the internet or the device which you get calls.

Did you try a different sim card in the device, does it working??? And does your service provider support LTE over call??? If it doesn't then change the preferred network type to LTE/CDMA/UMTS auto(prl). And switch your sim card to sim slot 2.

Problem 4G+ Galaxy note 10+ (SM-N975F)

Hello everyone, first of all I would like to apologize because I am French and I don't speak English very well, but I think you are my last hope for the trouble I am currently experiencing.
I own a Samsung Galaxy Note 10+ (SM-N975F) with a Rom Surcouche Operator Bouygues Telecom :
- N975FXXU4CTE9/N975FBOG4CTE9/N975FXXU4CTE9
I wanted to remove my Bouygues Telecom Rom Operator to install a Samsung Rom Stock without any overlayer operator. The operation is well finished so I am now on the Samsung Rom Stock:
- N975FXXS6DTI5/N975FOXM6DDTH7/N975FXXS6DTI5
Except that since this change of Rom I have almost no more 4G+ where I live knowing that before I was always in 4G+ So I would like to know why just by having changed the Rom I lost my 4G+. ( Worries which lasts since September 21st, 2020 ) I wanted to go back but I passed from a bootloader 4 to a bootloader 6
Knowing that I'm with the Free operator, I tested my Free SIM card in my wife's Samsung, I'm getting 4G+ so the problem is not my SIM card, I also sent my phone to Samsung, the phone has no hardware anomaly so it's from the change of Rom, I tried to reinstall the same problem, I also made the wipe I tried everything ...
I also have at home a 4G+ router with a 4G+ plan with the operator Free and I am in 4G+ at full speed ...
I hope to get some help from you because on the French forums I don't have a single answer ... Thanks in advance for your help and sorry again for my english

Test the internet speed on both phones using your sim's data plan with speedtest. If the speed is the same in both then the problem of the 4G indicator is only aesthetic.

Hello bigcalvin, unfortunately I have tested but the speed is not the same at all in 4G+ I go up to 235Mb/s while in H+ I go up to 3Mb/s so there is no problem with the 4G indicator

Have you tried in different areas? What it seems like, is that the stock Samsung ROM is not compatible with your carrier. With system on a chip (SoC), carriers can turn off bands that they don't need, or as a means of locking you into their network.

Honestly I'm not going to lie to you I've tried everything I've tried a Bouygues télécom rom (bog) a SFR rom (sfr) a France télécom rom (ftm) and a Samsung stock France rom (xef) with my old Bouygues télécom rom (bog) bootloader 4 I always get the 4G+ since I changed my rom and I switched to bootloader 6 I never get the 4G/4G+ again and I sometimes get the 4G+ logos but there are 10 seconds left and then switch to the H+. ..

Hello, sorry for the double post but I don't know where to find help you wouldn't have a solution to my problem? Thanks in advance
I don't understand anything anymore on this phone knowing that my wife and at free and I can receive the 4g very well. I have a 4g router, I can receive the 4g free and my phone since the update doesn't receive anything anymore, I have to go out of my house and walk a good 100 meters to hope to receive the 4g whereas I didn't have this problem before I made the really strange update...

No one would have a solution to give me or manipulation to do I take all the information.

Try a "reset network settings" if you haven't already.
Clear the system cache on the boot menu; it never hurts to do so.

Hi, thank you for your answer unfortunately I have already reset the network settings I have also done the factory settings system cache also reinstallation of a new rom I had to do it about twenty times but still nothing :/

Yeah pretty basic stuff... that's all I got
Most likely a settings issue but you probably know more than myself at this point to troubleshoot this problem.
Try doing Google searches and view the results for other Samsung phone models and years.
Most times I can find a solution like this or trip over it as an indirect result while searching.
Some of the Samsung software issues have been around for years...

I've already searched everything on google I'm French I've searched on English forums and everything but I can't find anything at all.
I am in France with the mobile operator "Free" which uses the frequencies 700mhz/1800mhz/2600mhz I would like to know if there is a possibility on this phone to choose the frequency that I want one by one I have the impression that it is my 700mhz frequency that has a problem on my phone :/

By using the free App 'Shortcut Master (Lite) from Google Play, you can get access to the Network Settings. In there you can make Band Selection, allowing you to test network connections and performance per band (=frequency) or combinations of bands.
See following thread: https://forum.xda-developers.com/ga...guide-hidden-network-settings-exynos-t3995501
Hope this helps!

Hello OnnoJ, unfortunately I have already tested with this application so it doesn't work. However I compared everything with my wife's phone a Samsung so I have exactly the same settings as on her phone ...
I have to go out of my house and walk a good 200 meters to hope to get 4G, however I specify that before I made this famous update I was always in 4G at home inside and outside of the house and this is not a concern of the mobile operator because otherwise my wife would have exactly the same problem as I have now and I would also have exactly the same problem on my 4G router ...
I think I've done everything and above all I've tested everything and unfortunately I had Samsung on the phone and they put the blame on the operator whereas as explained above my 4G router and my wife's phone have exactly the same mobile operator so they would have the same problem as me ... ...

I would try to revert to the newest firmware that your carrier uses, just to see if the issue is about the bands, search for the latest firm for your carrier, provided that it is of an equal or higher bootloader version to the one you currently have installed, that is what I would do

@thominekevin76000.
Not saying it may help you, but the application works fine for me to access network settings. I use it all the time, as it helps me at home and at work to make the optimum band selection for that specific location to prevent hopping between different cell towers and to have a stable and fastest possible 4G+ connection. CellMapper app allows me to see connection possibilities with the various cell towers and their power.

Hello winol, I can't go back to my old Rom because I had a bootloader of 4 and now I switched to a bootloader of 6 so I can't go back :/)
