Redmi 3s network issue - Xiaomi Redmi 3s Questions & Answers

Hi guys,
I have been facing really bad network issue for redmi 3s prime.. Basically there is alot of people facing this issue.. The problem is when network drop to 2g it will not revert back to 3g or 4g.. One of the facing issue sometimes when i drop it will go to IWLAN..
The workaround tips is we use 2 sims and sacrifice our sd card..which some of us dowan to..one other tip is to open gps and open google maps and let it run on background..which will drain our battery..
Some of the user said it is kernel issue, some rom issue and some said it is hardware issue..
I hope someone here will help to sort this problem..
Thanks and best regards..

My redmi 3s network is also week

same problem here! 3s Prime international

Yeah, I'm facing also quite poor battery life due to this continuous network search / reconnecting problem. The workarounds mentioned above, using 2nd sim slot makes a difference? Don't get the tip with maps... With active GPS the reconnect 2G - 4G e.g. Works? But GPS is a known bug by (most/all) cm based roms? I really hope the official kernel source will fix it. I'm using the international version of the phone as well, with b20 lte (as long as it's connected to it )

I have tried:
- Second SIM - did not fix it, seems to work for a short period, but was down to 2G again.
- GPS - sometimes works other times no.
Issue isn't with 4G for me, only with 3G. my phone will only connect to 4G and if it drops off 4G goes straight to 2G even with full 3G reception. I have only seen it connected to 3G on the odd occasion.
Kernel source is not likely to fix it. Only fix (if software) has to be the modem firmware I think.

I had a similar problem with 3s prime purchased from India. Turns out that the network problem is caused by the lack of bands in the phone. Eg. My network runs on the 850 Mhz and 2100 Mhz but phone had 900 and 2100Mhz. so when there is a variation in the network bands I used to get call drops and no network. Even I phone used to get 2 bars in the remote area but I had no service.
There are so many versions of the phone out there. you need to be careful which one you choose. If you have network problems, my money is on the lack of bands in the hardware.
I have these right now compared to 4G: FDD LTE B1/3/7/8/20(2100/ 1800/ 2600/ 900/ 800MHz), TD-LTE B40(2300MHZ) TD-LTE 2300(band 40) FD-LTE 1800(band 3) / 850(band 5)
3G WCDMA 850/900/1900/2100MHz UMTS 2100 / 900 MHz
2G GSM 850/900/1800/1900MHz GSM 1800 / 900 MHz.
Although some models are "international version" they may not have all the bands. I cant find the links now as I already got my phone 2 weeks ago but I know for sure that I have looked at many international versions not having all the bands.

hello, i had that issue until i disabled B8 GSM 900 band wcdma.
use "Network Signal Guru" to do it. Root is required.
here's a screenshot of what have i disabled.

If i did this I will never have 3G as my network uses the B8 900 WCDMA band.

My operator uses 900 mhz and 2100 mhz
My phone has never, ever connected to 900 mhz band
Your operator must use two bands atleast for one connection
Try to disable it, its very easy to undo the process
Feedback me with results. Regards

I disabled 2100 band instead of 900 and testing now. So far i haven't dropped to edge but lets see if it lasts.

I turned off 2100 band WCDMA and began to operate normally (except data in the lte)

Exactly the same in my case. I disabled the 2100 and it is working better. But also I still dont have any 4G network

I encounter the same problem ! Disabling all the LTE band and 3G band and leaving only the B20 LTE band and 2G band make the phone works properly in 4G.
(My Carrier is Bouygues Telecom in France. It uses the B3 and B20 band for the LTE)
This is really usefull as the phone was really so unstable i coulnd't use it normally to call or receive calls neither receiving or sending sms !
With this trick, at last i can use my phone.

Yes. Quote from the spec sheet:
HSDPA/WCDMA: Europe: 2100 MHz / US:1700/2100 MHz
Up to 7.2 Mbps down-link (HSDPA) and 2 Mbps up-link (HSUPA) speeds Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz (Band frequency, HSUPA availability, and data speed are operator dependent.)

Actual up/down thoroughput is more limited at this point by T-Mo's 3G buildout and network load than the hardware on the G1 at the moment.
Is HSDPA enabled as default? I've only been reaching speeds of 300-400Kbits/s.
It doesn't have to be enabled, it comes under the generic '3g' option.
It depends on whether your local tower is HSPDA enabled. Most are these days in cities, but there's the odd one that doesn't handle it... and if you get out into the countryside you may find there's no 3G at all.
How are you measuring it? The browser rendering speed is limited by the CPU for example, so it isn't significantly faster on Wifi than it is on 3G (you could tether & use a laptop to mitigate this).
Even the speed test programs aren't great, as they test against US servers which means they're measuring the speed of the link between here and their servers in the US rather than the phone speed.. Xtreme Labs Speedtest for example gives a reading of 247Kbps on a 15Mbps link over wireless, and 133Kbps on 3G (My dongle can pull 6Mbps off the same cell).
I've seen a solid 788/113k from my 3G, in Central CA, via XL Speed Test. Much better than the 300k I used to get on my Hermes (Edge only).
I wat to see how the network fairs in SF/LA on my next trip.

There's a way to tell without a speed test. Use anycut or bettercut program and create a shortcut to phone info. It should say "network: UMTS". HSDPA isn't active yet. It will have a big "H" by the signal bars when it's turned on like any other HTC phone. Phone info is a great way to change your preferred networks over such as "WCDMA only", "GSM only",or "WCDMA preferred". Humm... maybe I'm wrong this speed seems really fast for regular old UMTS. I checked my HSDPA CQI Status using the fieldtest shortcut and had some activity. What do you guys think? Could google be foolish enough not to include a "H" icon for HSDPA when all other HTC phones do?

UMTS maxes out at at 384kbps, and your speed test clearly shows faster speeds than this, so you are definitely in HSDPA territory.

I've never seen a "H" appear in the top and believe that it doesn't have one. It is just included under the "3G" symbol and anything slower than that I get a "G".
Getting about 900k in York, UK.
Yeah, I thought UMTS maxed out at 400 kbit per sec also. That's crazy about the "3G" icon not changing into an "H" icon. It's so un-HTC like... on well. Guess it was a WM thing. Weird though, "G" will change into "E" and then into "3G" but that's it?! Oh well, I guess I'm a little too hung up on this, lol. I'll leave it alone now.
Something in the back of my mind wants to say that WCDMA and HSPDA are similar and sometimes interchangable. And because of terminology issues 3G is now used instead to signal WCDMA/HSPDA

Actually depends on the 3G release the service provider is using... for instance R99 would max out as 384 yes, but R4 which introduces HSDPA can max out at 14.4Mbps down and R5 which introduces HSUPA can max out at 2Mbps UP.

Yes, we know! The point is that "standard UMTS" (for want of a better phrase), as opposed to "UMTS with HSDPA", maxes out at 384kbps. This nomenclature is based solely on the observation that many phones represent a 384K 3G connection with a "U" or "3G" and HSDPA with an "H".

The only icons for signals are G, E, and 3G. This seems like a OS issue as it's not included in the framework-res.apk.
Says H
But isn't HSDPA considered 3.5G?
Well since I see this thread here. I know in VA on my HD2 after i put energy rom on it, I DO get a H from T-Mobile. I know they have it here but not rolled it out officially on their phones unless you have your phone modded to access it.
My G1 however is only stuck on 3G so makes me think G1 cant do H? Or does it need a custom rom for it to be enabled? Anyone know?
Why my G1 doesn't switch to HSDPA ??
Sorry to get out this old thread, but I didn't find any informations about my problem ...
My phone : G1 (from Orange, France) rooted with Cyanogen Mod 6.0.0 Stable and radio : 2.22.23.02.
I'm sure to be in an HSDPA zone because when I put my sim in a Samsung Spica (stock rom), it switches to HSDPA.
I didn't manage to make my G1 to switch to HSDPA. Every time I check in "settings/state", it's always in UMTS mode (signal intensity : -63dB)
More : I tried to downgrade to the previous radio : 2.22.19.26I. No more success.
I try to modify the build.prop without any improvements too.
Note : For each test, I always checked the state of the connection in settings, and make speed test with XtremLabs Speedtest. Nevers get download upper than 357Kbites/s ...
Hope somebody have some advices or explanation ...
Thanks for your help !
I tethered my desktop machine to my G1 and then ran the mobilespeedtest website- I was hitting ridiculous numbers that were stupid unbelievable! I blew away the highest rating on their chart be several multiples. I think there was something funny going on with the test since I would get better results with larger downloads. I could be off by a factor of 10, but I think my download speed was in the ballpark of 14,000 kbps. It seemed ridiculous, so I didn't think it was real. I can hit 2000-3000 kbps sometimes with just my phone on mobilespeedtest.com
I was the Chicago when I tested it and hit those ridiculous speeds. I also tested it in Miami, which has the HPSA+ upgrade and it seemed faster in Chicago, but I wasn't able to test it tethered with my desktop machine.
I know these numbers seem off the charts and there might be something that was throwing them off.
EDIT: I checked the results - 7,143 kbps and 26,230 kbps. If my math is correct, that's almost 200MB/min! Again, I think there is something wrong with the test, but the 7K number might be reasonable?

S5 G900L LTE problem in Europe zone

Hi, i have an S5 model G900L but i live in europe and seems it use different band frequency (850 instead of 800?) for LTE.
I'm able to get gms 2G/3G network but not 4G also if i have a 4G LTE enabled plan from my provider.
So i tryed to flash with odin g900f firmware on my g900L it fail for secure check.
I flashed it with mobile from device and SD odin and it worked. but device wont boot and redirect on download skin for odin for boot failure.
I also tryes to flash only modem part of firmware. phone boot but no 4g yet.
I hear the chip support all LTE frequency so it should be a parameter/soft problem.
There is any exploit for enable or costumize LTE frequency of my G900L for my geographic zone (europe)?
My device is rooted and with cwm recovery 6.0.48 working.
Correct me if I'm wrong, but frequencies are a hardware capability, not software. So the hardware you have is not capable of supporting that frequency.
I'm not sure LTE (modem) chip is integrate into Snapdragon 801 processor. Every model T-F-L-I-A etc have same hardware chip "Gobi" should be MDM9625 model.
Chip is able to work with multi-band so if frequency are not fixed into something like an eprom of gobi for each model i guess it just work with drivers/firmware loaded on device boot.
I found a file in root>dev> __properties__
and found a different modem model
"MSM8974PRO"
with all specs and was a row interesting about gms band
Code:
ril.skt.network_regist_status „ÿ baseband
G900LKLU1AND2 gsm.version.baseband operator 8 ´ H numeric 22201
gsm.version.baseband operator 8 match with korean skt operator maybe i should switch it to 5 (european LTE band).
I wish to try replace some file from stock g900F firmware but have few issue to extract system.img.ext4 on wndows.
so i can't test if replacing firmware ans some setting file want let me able to connect on a different LTE band
Hello All,
I have the same phone, SM-G900L and it works properly in France, 2G, 3G and LTE without problem.

and about 2G,3G and LTE are you able to switch data mode from "mobile network" menu?
Mine G900L not show me switch option
can you post a screen of your menu is look like this?
Yes, I get the same screen each time I start the phone and like you, i'm not able to find the menu to switch networl option.
I will take the screen captures asap. But for me i can get the LTE without problem.
Do you mean guys that if I bought a galaxy s5 model SM-G900F I can flash it with another model frimeware like SM-G9008V or SM-G900I and the 4g frequencies will will work fine after the flash???
Hi all,
I am having the same issue with my G900L (on Baseband G900LKLU1AND2) in the UK - 3G is fine but no 4G (SIM is 4G ready). I am getting the same prompts that ramsesxv posted as screen shots. Ramsesxv have you found a fix? Does anyone else have any ideas please?
I just got my s5 g900L. I too had problems with LTE. But I found a fix from another post.

Hi Bimmerboii,
I also have an unlocked SM-G900L which I picked up in Hong Kong and use on the 3-mobile network in the UK. I have changed the Data Setting to Auto and will wait to see if it can pick up a 4G network when I am next in London.
Could you help with some of the additional settings please? The Phone is LG-Uplus branded and is set by them to always be in roaming mode when I am in the UK. If possible I would like to make the UK my home network. Under Data Setting there is a submenu called Roaming Realm. Entering this opens a dialogue box with Cancel and OK buttons. Would you know what to enter here to set the United Kingdom as my home country?
Many thanks,

I'm confused by your query, I've just bought this phone from an eBay seller (wish I'd researched beforehand, but hey oh) and will also be using it on the Three-UK network when it arrives. I'm convinced it should work on 4G though since I believe Three UK is using the 1800mhz (correct me if I'm wrong) band for 4G which this phone definitely supports. Other than that, have you had any other signal issues in general?

Hi,
Overall I am really pleased with the phone, and the reception has generally been excellent but I have never managed to get it working on 4G. I can't say I have spent a lot of time trying, because there is no 4G signal where I live anyway.
It may well be hardware compatible, but the connection settings imposed by the Korean issuer will not allow 4G in any country it sees as roaming (ie not Korea). It works fine with Three in the UK and I have used it extensively abroad on Three's Feel at Home contract without any problems.
If you do come across any sort of firmware update that allows 4G in the UK, it would be great if you could let me know.
Thanks,
Chuffbaby

To prevent more users from paying way to much for a SIM card (sorry @noahvt ) I've created this thread to give some small intel about the used frequencies of the Sony Xperia SP and the use of them on your vacation.
First some small details about the case:
When you use your device as normal it is connected to your own operator. For example; I own a Xperia SP Int. LTE version and my operator is VodafoneNL. I use it normally and I have (almost) alway proper connection.
When (and this means when I win the lottery) I go to the USA I am unable to use my phone with full LTE and 3G. Reason for this is the frequencies from the American operators.
Some intel about our Sony Xperia SP.
We all know its hardware but do you know which frequecy bands it supports?

Most common question:
Q: How can I use my phone on my vacation then?
A: Depends on your location*
* see Intel about DataRoaming
Data Roaming:
Data Roaming is uses by your phone to sent and recieve data from unsupported operators. This is mostly used when your own operator has no coverage in a certain country or location and you need to use your phone.
Data Roaming does cost extra money! So you have been warned!
Roaming only works when the both operators (your own and the one in the visited country) got a Roaming Agreement. If this is not the case you cannot use data roaming!
How it works:
When the phone enters another operator coverage it will be noticed and the operator will try to locate the orignal operator to see if there is an Data Roaming Agreement. If this is not the case the phone gets denied on the network. If the two operators got an agreement step 2:
The other operator tries to get in contact with the original operator and requests intel about the phone. The original operator gives this intel; IMSI number, SIM Number and the services it supports.
When this intel has been delived the phone gets a temporay phone number with the "roaming operator". The orignal operator gives the "roaming operator" one intel how to connect to the original network.
(Ma English is poor sorry 'bout that..)
When your operator has no Data Roaming agreement with the other operator you have two choices:
Buy a temporary SIM while you enjoy you vacation
Turn the phone off and don't use it during the vacation
When you go for option 1. Remember the supported frequency bands at the beginning of this post.
The C5303 does not support certain bands and the same is for the C5302 and C5306.
Some support pages for you:
I need a bit more pages! Please sent me the one from your operator so that I can add it!
T-Mobile USA
3 Biggest Dutch Operators (on one page)
I am still working on this thread but for now you have some small intel about the use of the other operators!
Please be a smart user and ask your own operator (or store where you've got your phone) for information about the supported bands and operators in other countries​
great effort but i got c5303 and my sim which requires band 2600 doesnt connect in my phone

MI Note 2 Users - Please test and confirm WIFI/4G/bands

Hey guys,
As this is a new release, I am keeping an eye out for tests of the stability and reliability of 4G LTE connections (the reception) and also the same for connecting over ac WIFI. Can someone please post some tests/videos/results?
Second. can someone also take a picture confirming ALL 4G LTE FDD bands supported. GSMArena and PDAdb.net both state this supports Bankd 29 700Mhz. is this correct?
Thanks

I have the CN edition rather than the global so I wouldn't expect to have Band 29 so I can't help you there.
In terms of general stability and signal quality with LTE connections.
They're very good.
I'm not sure what kind of test/video or result you'd want to see as it seems like there are always too many variables to get consistent test results, I can quite happily get 70mbps down on LTE using band 3.
As for WiFi - I'm hoping this is a ROM issue more than anything else, I'm unable to set my locale so I don't which nations wifi regulations I'm following (I'm using mi-globe.com as there isn't currently a global release rom).
I max out with a link speed of 433mbps on 5GHz (desktop achieves 1300mbps) and can't achieve more than a stated link of higher than 150mbps on 2.4GHz (desktop achieves 600mbps)
although the range is very good, and the eventual handoff to LTE is very quick too.
Is there something specific you're looking for I can help with?

Thanks for that. Yes, I think there is. Maybe see if you can set LTE only, or LTE/3G (etc)...do you get full reception at work, or in your home? Maybe just monitor it's strength without moving the phone from a typical "full strength location" and see if it changes. You can also run other apps that will utilise more of the CPU and RAM 9not necessarily internet-demanding apps) to see if they are a factor, in any way, on the radio strength.
I am mostly interested in the global version, what ROM it is (hoping different rather than just the CN with extra languages). As it's important to see what bands are supported, usually mentioned on the package... I also need to see the functionality of the dual sim and how the 2 interact when a data connection is active and a call comes in on the other SIM, etc. Screenshots confirming the SIM's connection sin the upper right status bar would also be benefical.
Thanks

Set to LTE only I get full signal at home and I haven't noticed anywhere in the city I don't have 4G, (at least while above ground).
It's not easy to make too much of a dent with that amount of RAM but CPU increased utilisation has no affect. I tend to keep my signal details as numerical anyway, that changed today when I flashed a statusbar mod changing my clock position so it's not in my screenshots.
You won't be seeing a difference in the ROM with global version, there isn't any reason to think they're releasing a separate ROM for the global version. The ROM that's out now is for all versions, I've taken it apart and the support in the current ROM is there for all the bands. I haven't worked out where they're limiting the bands but I've had a tinker. Changes to NVRAM values are lost on reboot and I haven't got any real reason to play other than curiosity.
If they release the phone internationally that would be when they release a global ROM; the differences there are localisations, removal of Chinese local apps (baidu, etc) and inclusion of google apps instead but nothing much more substantial than that. Was there something in particular you were hoping for?
No problems running data on one sim and receiving a call on the other, I tried this a few times downloading on LTE and calling myself via Skype (to my number not Skype -> i.e not local cell or data call). 10 out of 10 times there was no problem receiving the call and no noticeable impact on data speeds at the time.
Not sure how I show you with screenshots that one sim is active for data while another is active for voice, there's no indication when a sim is being used besides for data but I've taken some running an LTE network scanner. It'll only show networks on the band I'm currently active on (no idea why). Searching for available networks to join I can see LTE networks that use must band 7 (I assume, since that carrier has bands 7 & 20 - and well I shouldn't pick up band 20)
Hopefully you can gleam something useful from some of these screenshots, these were taking live as it was running. Since it's just network scanning here's no actual data flow hence why you see there's no data activity in the statusbar.

@StoneTrapper How do you find and rate the UI?
I've heard there's a few who don't like it and want to switch phones because of it.
I can see 4g/3g from your screens, so I wouldn't think using 4g and taking a call over3g frequency would be an issue given the CPU in this. THe lack of Band 28 (or many other bands for that matter) is a bit concerning

I'm used to MIUI, it's not my first xiaomi phone. I don't mind it, it's not ideal but there's nothing really unlikable about it.
People will always have their own preferences with roms, sooner or later xiaomi usually release the source code and the custom roms come flooding.
Yeah one of the networks I'm with only offer 3g, otherwise it supports dual LTE. If you want additional bands they offer a global edition that supports:
B1, B2, B3,B4, B5, B7, B8, B12, B13,B17, B18, B19, B20, B25,B26, B28, B29, B30
TD-LTE: B38, B39, B40, B41
I don't need the additional bands and the CN edition is already available to I went ahead and got that.

(Experimental) Enabling 2xCA support support in RN4 - Mido

Mi Guys,
(Standard word of Caution: Risk of bricking your phone! Only proceed with, if you understand what you're doing)
After becoming very happy to see dev supports on our Mido, I was very desperate onto enabling LTE+ (Actual 4G) on our device over Bands 3/5/40 for Indian 4G only operator JIO.
SD625 - Actual Hardware supports it so if software support is enabled theoretically it should work...
Hence I followed this guide (https://forum.xda-developers.com/lenovo-p2/how-to/enabled-4g-ca-p2-t3707584)
After using 549755813908 value and restarting the phone, I got very happy to see 4G+ on MIUI9. BUT BUT BUT, Phone actually doesn't aggregate with two carriers still! What happens now is whenever the phone is in Band 3 or 5, this + sign just appears.
After that, I flashed NOS ROM and even now, LTE+ appears, but actual carrier aggregation doesn't happen. I can confirm No Data Speed improvement whatsoever and can confirm same using NSG App. Pls, check Screenshots attached. Any leads are most welcome!

Band 5 has slow speed due to its 5Mhz bandwidth. Remove it and try locking on B3 or B40. I am sure it will provide you faster speeds. B3 has 10Mhz and B40 has 20Mhz bandwidth.
So i removed band 5 from my phone to have better speed and it worked.
ChinaTelecom 4G Band1+Band3
Mido Can not use it
is there any trick to use internet on 3g sim and 4g sim volter for calling only, means if i change default internet to sim other then jio , then jio should get network only for calling

While that correct, the point about this post was to enable CA in Mido. Most of the articles point 625 chipset aggregates stably over Band5 with 3/40. Anyways it doesn't aggregate on any bands, as I explained

So far nope..
May be this is due to locked nv values. When was trying to modify nv values for LTE bands i found that many other values were disabled.

So, what is ur final suggestion? Should we unlock ca and b40 to get 10m+ speeds or shouldn't we?!

By NV values did you mean changing RFNV LTE B(x=No.) CA BC CONFIG..? If so thats exactly what I tried and it didn't work to me

You can try to enable 2CA by following my thread. But it doesn't connect 2CA as expected hence no speed improvement so far.., I have no clue what is going wrong. Thus I created this thread to gather some inputs by some experienced guys who know about this..

What about this guys (see pic, attachment) !?? Pic are from MIUI forum post about unlocking CA 4G+ on Mido.
Dont close the thread .It will be a boom for mido users Just some more time and knowledge of others Seniors is needed Please

It was proven it doesn't work, since why OP removed all the files.
It's useless even in those bands the jio speed is capped.
