Redmi 3s Prime data speed dropping to E and G - Xiaomi Redmi 3s Questions & Answers

Hi all,
I have bought a Redmi 3s Prime last week. One problem I am facing is that if you turn on data services, if it is idling, speed drops to E and even G. The only way to get it back is to manually change network preference type from settings. What could be the problem? Is it a hardware issue?
Android version 6.0.1
MIUI version 8.2.5.0 (MALMIDL)
Please help.

This is a known issue.
Is you have root, try to install Networl Signal Guru, then disable Edge (2g) frequencies.
Some people solve it using a second sim...

Second SIM even if dummy one will solve this problem, I'm using this option and managing my 32GB wisely as you will lose your sdcard slot. Nothing terrible for me as I need it the 2nd SIM anyways.
slds,

Your problem is well known, but still no solution from xiaomi.
Best i can suggest is that u check which frequencies your carrier uses.
If u got root, install Network Signal Guru.
Try disabling one of used WCDMA frequencies and then force 3G. if it doesnt work, try to disable the other frequencies
IT WORKED FOR ME D

Switch to global dev rom you will get the latest one. Miui 9 v 7.9.8
Better you make clean install with MiFlashTool via EDL.
Search fastboot rom here.

CM13 for G900FD

CM13 is available: http://www.cmxlog.com/13/klteduos/#
Seems to be quite stable for its early state.
Known issue is that most apps can only read from external SD, but not write because of changes in storage management of Marshmallow.
There are also voices saying LTE & 3G are not working.
Please test and report
Not working LTE and 3G , clean install....
Yeah same here, no LTE 3G. Clean install
Bad news 1st: LTE not working seems to be a known bug, too: http://forum.xda-developers.com/nexus-4/help/cm13-switching-to-wdcma-t3280353
Good news after: It seems to be already merged since yesterday : http://review.cyanogenmod.org/#/c/125897/
I have already flashed today's nightly and maybe, later on, I can sort out if it has been already fixed...
I hava had no problem with LTE/3G since day1.
I only get either G, E, H or H+ connection, but not yet 3G or LTE...
I had no data with 31st december nightly, came back to cm12.1.
I look forward this cm13 is stable !
LTE in Germany works (T-Mobile).
Really? I am German, too, but only G, E, H or H+. Provider is Vodafone.
Really! Perhaps another band?
No problems here. But using external SD is a problem. Any solutions?
No, not yet. Marshmallow has completely new memory management...
Mi Band no works on Bluetooth.
My xiaomi Mi Band no longer works with the cm-13.0-20160112-NIGHTLY-klteduos. Just can not be detected by ROM. Someone with the same problem?

You have to switch to other sim and turn that sim to 2G ( u may not turned to LTE before but it automatically turned into LTE) then switch back to data sim the ntry to change it to LTE or 3G..

Possible the same Problem in my reason. The mifit APP detect the miband but can Connect with it because the miband think its still connected with an other phone.
Next update i unpair first.

Hello everyone,
I just flashed cm13 and found 2 bugs so far.
1: no setting for disabling either sim cards.
2: no setting for not pressing ok after inserting pin to unlock phone.
Anysolutions yet??
No. CM 13 has not been officially launched yet. It is still under development and proceeds step by step.
I have updated to stock 6.0.1 and updated Bootloader and Modem accordingly.
But from then on, I can't install CM13!
it gets in boot loop.
Has anybody been able to install CM13 after updating bootloader to 6.0.1?
@pc boy: it's not working atm, see https://forum.cyanogenmod.org/topic/125006-cm-13-wont-work-after-official-mm-upgrade/

Android 6...
Anyone having a 5GHz Fix for K3 Note with Android 6 (Marshmallow) ?
The one above doesn't work with the latest version.
lenovo k3 note android 6.0 MM 5ghz support???
i have the same problem with my k3 note: i want to use the phone as fpv-goggles for my yuneec q500-drone, the drone camera cg03 only connects to 5ghz-phones as my old galaxy note3. but now i want to use the k3 note and its "vr switch mode" for fpv-flying....but the k3 note does not receive the 5ghz-signal. the apk download MT6752 5.0GHz Enabler does not support android mm 6.0...
who can help me,please!
I have S424 rom, and the 5g wifi does not work. my phone cannot see it. anyone who has a success can share some ideas? also , the S424 rom has very good battery life, but the wifi is pretty slow than 1613 rom. if you run a speedtest, most time, the s424 rom has only half of the speed in the same test conditions in my house.
Hi!!
Same problem Android 6.0 dont work.
Any idea?¿
Also need help with this.
I know this phone supports 5Ghz networks, but it doesn't show.
I tried fixing it trough Engineering mode, but it crashed on me. :/
I'm running android 6.0. Anyone found a solution yet?
I follow instruction from this link: http://www.needrom.com/download/enable-5ghz-wifi-with-sp-meta-tool/
and did successfully enable the 5Ghz WiFi permanently. Follow each step properly til the end, make sure step 12 and 13 are done, otherwise you have to redo again.
but 1st, you need to have root and a custom recovery TWRP.
I accidentally wiped out my nvram partition when upgrading to a Marshmallow rom with SP Flash Tool and wanted to re-enable 5ghz wi-fi.
Unfortunately, I couldn't get the needrom.com tutorial working due to the SP Meta program not detecting my phone properly (probably due to a driver issue).
I did find a workaround if you are rooted. View this link: https://www.android-hilfe.de/forum/...recovery-root.739625-page-2.html#post-9457294. The page is in German so you'll need to use Google Translate.
Anyway, to summarize, the solution is to modify the following file with a hex editor - /data/nvram/APCFG/APRDEB/WIFI. You will need to modify the C5 and 106 byte offsets from 0 to 1. Next, you will also need to delete the last two bytes of that file. Then save and reboot your phone and the next time you turn on wifi, you should be able to see your 5ghz wifi network again.
The problem with this approach is you might need to redo this if you ever wipe out your /data/nvram/ folder.
I just wanted to write this up just in case I ever run into this problem again

Still on B124. Huawei is slow to roll out updates it seems. Not even available as an 'early update' through the HiCare app.
I am still on B121 and no notification of updates even though I check every day.

Guessing it depends on your country region .Anyway there is not much diff notice before and after update .
Ppl, does anybody had problems with this phone, now it's a little bit better, something I'm not doing anymore probably, but when I changed predefined apps on my phone I had to restart 2x a day the phone, huge lag and locking.
Had to shut everything to keep it simple...
I really need a CM rom on this... as Stock android as possible.... EMUI is destroying the performance.....

MI A1 Network fluctuation with custom ROM

Hey Folks, as we all know how stock ROM sucks, I remained on custom ROM to max extend. But sadly I have to revert to stock due to network fluctuation issues. I use Jio as my primary and Airtel in SLOT 2. Fluctuation is widely seen in slot 1 which is reported by many others as well in respective ROM thread.
I have tried methods flashing custom modem image and network signal guru. But none seems to fix the case.
Anyone aware of other methods to fix the network fluctuation issues seen in custom ROMs? May be using any custom kernel?
Please help me to remain in custom ROM!
Cheers,
Hari.
Same here all cust rom has this network fluctuation issue and it is to do with the code. It seems if any one can fix this. It will be great..

The same, please helppppppppppppppppp!!!!
Noticed the same on Vodafone AU, no matter what network mode I set it to. Even on 3G only I get drop outs and fluctuations.
I'm hoping it's just some extra modem related package or service missing from the vendor blobs, but I've not had time to look into it yet (with my limited skills in this area).
For me also lot of fluctuations. Sometimes totally black signal bar. Hope somebody can fix it. I fixt it for now with automate and set network to 2g when on wifi and after lock screen when I am on mobile network.
Modem zip in forum don't solve it for me and also lock some bands with signal guru didn't do the trick.
Hope somebody can solve it a lot of people are suffering this problem.

Has anyone tried using custom kernel? Just curious on if any custom kernel fix this.
Same issue I have been facing, I had re-partitioned my device for Treble using CosmicDan's guide so that I can try all the best custom roms out there and get all updates as they are released but when I faced this issue, I had no choice but to revert back to Android One rom, undoing all the process

Probably resetting modem settings, assuming you've made any.
China only uses maybe 5 bands, and most of the population doesn't often travel far from home; so roaming and tower switching isn't an issue. That, and a power management issue I think are responsible for our network issues.
My money is on these devices working perfectly in the motherland.
Faced the same , almost on every custom ROM .Jio 's volte doesn't work most of the time. Switched to January stable stock twrp with magisk . Now everything is stable , no volte issues at all .
Now my question is , the issue is with ROM or modem file ? As you guys are saying that it is a modem issue ..as now I am on January stable modem , I will try to flash a latest build of any custom ROM and will report .

There's a TWRP flashable May modem patch somewhere in the MiA1 forum. I've flashed it and the results aren't perfect, but circumstances have improved.
I have tried all March, April and May modems and all have problems with custom ROMs and network fluctuations for me. (IND Airtel operator) and even 3G is fluctuating with state owned BSNL. January is the only one I haven't tried which I will after getting a reply from sikoo1996.
I have very limited knowledge of these matters and so far all my attempts with dialer code menu or settings or Network Guru have all failed. Guess I will ditch this phone and stick to my S5.

I dunno if it actually works for everyone but,
Swapping the SIM card slot worked for me.
Using RR latest. I also flashed stock modem.img but that didn't fix the problem then. It's fixed now by swapping SIM slot.
Hey guys. Try flashing the latest modem and then, go oh ahead to *#*#4636#*#* and select network mode to TD-SCDMA/CDMA/UMTS . ?

Xiaomi Mi Note 2 does not search LTE

hello, I have a problem with my Xiaomi Mi Note 2. Once I wanted to unlock the LTE 800 band, unfortunately it failed. And now I have a problem because the phone does not log in at all and does not find any of the LTE network. I did something wrong in NV Ram. How to fix it now? Reinstalling the kernel will help?
No. That is not part of the kernel. You need to get those settingsthat were changed reversed... This is my opinion...

Yes, which one you want to use depends on what version phone you have and what you want to do afterwards.
here are the Global ones:

Sorry, I have no more good ideas.
You should try some different simcards, from various operators, of course.
