Question Mobile Signal Module - Xiaomi 11T Pro

Hi All,
I moved over from Samsung to the 11t Pro and am loving the phone so far. A few tweaks needed here and there, but generally its a cracking phone for the price!
The only thing i do have an issue with is mobile signal. It fluctuates constantly between strong signal and no signal. This could be related to the network, but I don't have another SIM to test this with and never had the issue with the Samsung, although that wasn't a 5g phone.
I know with Samsung you could flash independent mobile modules. I cant remember exactly what they where called. Basically some would have amazing battery life, but rubbish signal and others have would give amazing signal at the sacrifice of the battery. Some where perfectly balanced.
I'm not sure if anyone knows what I'm talking about or could shed any light? I'm wondering if there is something similar for the 11t Pro?
Cheers!

Just remembered it was the modem modules! Are these available for the 11t Pro, so we can flash and test different ones to increase battery life or signal etc.?

I've the exact same issue and I can confirm that the issue is caused by some networks only because I tried multiple sim cards and I got the issue with only one network and the others are working fine, but this specific network has good coverage and works fine with other phones, is there anything I can do to fix the signal drop with this specific network?
Thanks.

SE Responds to Signal Strength Problem

Hey guys ... I was just reading on the SE X1 blog (http://sonyericssonxperiax1.blogspot.com) something about cool X1 accessories and was very surprised when I read this:
"Other accessories include things to boost the phones use, like memory cards, an easily applicator chip to boost signal strength, car chargers to keep your Xperia working while travelling, and many others..."
Now I know that I m one among many here that think that x1 signal strength is very poor .. has anybody heard about this chip before and where can I get it, how much does it cost, how effective is it and how do you use it?
regards
I don't think that blog is official, and I highly doubt those "chips" actually work.
reception on the phone is poor. driving, building, walking... you never know when it's gonna go. pain the jane.
Those signal chips have been around for almost a decade. They don't work but don't take my word for it. Go to ebay and order yourself one.
well .. this blog isn't official ..
plus , i haven't ever faced a poor signal since i've been usin my X1

u will, i have fall signal whilst writing a text and by the time i have finished its trying to find a signal, even though i have not moved. im hoping that the r3 firmware improves this in some way, maybe release a new radio for the x1
I have any X1a on ATT and the signal sux. What's really weird I noticed is that the call is never handed off either (3G to E). Instead, it drops the call completely and then goes to Edge.

I've heard complaints about this with the iPhone 3G too. Probably an AT&T thing rather than the X1 in particular.
I'm on T-Mobile (so EDGE only), and it's been as reliable as any other phone I've had (aside from T-Mobile coverage sucking in general).

As far as I know, the signal strenght problem only affects some countries (UK, some part of USA, ...). It much depends on the operator infrastructure.
Here in Netherlands i dont have any problems with signal on 3g i can browse every where i want

i am in the uk, but my old sony w960i never had a problem. sony has already said that the signal is weaker due to the metal housing of the handset but there is a signal booster in the handset that comes on if it looses signal but sony says if drains more battery
I've the same problems too. I have to switch off the 3G/WCDMA to get the strong signal..btw, I'm from Indonesia..
yeah the signal is bad all my old SE phones had no problems but x1.....
Reception is fine here in Austria too.
And please, stay away from these chips. Only thing they do is stealing your money out of your pocket.

The problem is not with browsing... you barely notice a drop in the speed or change from 2.5G to 3G.
The problem is when calls drop or everyone else around you seems to get reception and you're still tapping 'please resend message'.
Might seem like a small problem to some but I'm doing around 2000 minutes a month and it get's on your nerves.
I like the phone so am looking for a fix / update.

Same in Belgium... No problem with the signal Strenght, often I am in HSDPA mode

This really seems to be an AT&T Problem. My X1 hands over 3G (actually 3.5) and Edge quite well during calls. I have here a low 3G signal, but good Edge signal. 3G is prefered so I´ve an handover quite often.
I'm on Vodafone in the UK and while my colleagues on the same Network have a signal using other phones, my X1 invariably does not. I usually have to go to the other side of the office to get a signal. Hope new firmware can sort the problem out.

I've got ATT/X1A in NYC and have no problem unless I'm in some basement. Perhaps the OP has limited himself by selecting a particular band and/or network type? I know if I purposely select WCDMA my 3G will drop because it's pretty spotty out here. Call quality is perfect if I have them both on Auto.
New firmware isn't going to fix it. It's a hardware issue caused by the build of the device, structure and materials used etc - they are blocking the signal slightly.

Signal strength bars fluctuating

Hi guys, I just got my Incredible S yesterday, and I absolutely love this phone!! The only problem so far is the fluctuating signal bars. I'm not sure if this topic has been discussed here, but it seems to me that when I hold the phone...my signal gets weaker. When I put the phone on down..the signal gets stronger. Does a rubber or silicone case help as far as limiting signal interference?

I'm talking about 3G/H. It's such a shame. I really liked this phone, but designing the antenna on the battery cover is a huge flaw. What were they thinking?!!??
I also have the signal strength fluctuations. I have tried everything: changing the SIM card, changing operators (Swisscom and Sunrise), changing settings GSM alone, WCDMA alone, and GSM/WCDMA auto, and soft reset. The only thing I have not yet tried is a hard reset.
I wonder if somebody else has the same problem? The consequence of this problem is that often times the quality of the calls is lousy and/or the calls are dropped.
Please help me..
Have to say, my signal level is dreadful compared to my bog standard Nokia mobile phone in low signal areas, I get no signal on my Inc S while 2 or sometimes 3 bars on my Nokia. It's really spoiling an otherwise brilliant device. One thing I was wondering is if changing radio from the 22_M to the 27_M might help, anybody know what the difference between them is ?
and, data does not work over 50% of the time on gprs, but fine on hsdpa/3g/edge, don't know if that's also down to poor signal reception ?
I had the same problem with my IS. when the internet connaction GSM/WCDMA auto i had many unexeptable call ends. I put the internet connection to GSM only and every thing is ok. Acording to info i have the problem is in some operaters new software when the network type changes the telefone cannot change it normaly.
After visiting other fora, I have a crucial question to ask: is the reception problem (fluctuating bars, dropped calls, WiFi disconnecting) a generalised problem, or, rather, is my phone faulty, and therefore should I have it repaired?
HTC update the radio module immediately....

I also believe that the desire s has this same problem they are similarly designed devices now running with very similar software.
even though at times signal can be great without moving it can drop to nothing and I'll lose all signal, which I believe has caused me miss several calls as they've gone to voicemail rather than ring on the phone.
I'm hoping that an upgrade to the phones radio will fix/improve this over time (the optimistic outlook)
Sent from my HTC Desire S using XDA Premium App
signal
its the antenna design =Fail , put it flat on a desk and dont hold it and watch your signal go up pick it up and its like an hour glass going down
I am now arriving at the conclusion that sound quality and dropped calls (and bars fluctuating) can be explained by a connection problem when using GSM/WCDMA Auto. The problem disappears when using GSM Auto. Any views?
Same here, but it is better on "wcdma only" either. I'm suspectinig it has issues only when switching between wcdma and gsm

Losing signal reception for couple of seconds throughout the day

Hey guys, my OnePlus 3t is losing signal reception for couple of seconds throughout the day. First the Internet cuts off ("4G" mark disappears from the status bar) then all signal bars are goneand after a second or two it comes back just fine. Did anything like this happenes to you?
The same SIM card works fine in Samsung phone in the same spots.
I sent my phone for repair, it came back with replaced PCB but the issue is still there.

Hi,
Did you ever find a solution to your problem? I'm having the same issue. Random complete drops of signal for a few seconds.
I'm also having issues with the radio in the phone. This last week I purchased a different phone to see if the issue was my cell connection. The replacement phone worked much better and faster on a LTE connection in the same locations. My issue is same as OP but I also lose LTE+ frequently and the speed and throughput drop to <1mb/s. Love this phone but getting frustrated with it. I'm running stock OOS, unlocked bootloader with root.
I have also same problem and I tried
this
1. Open dialer
2. type *#*#4636#*#*
3. Select phone information
4. Select "LTE only" from
"set preferred​ Network type"
5. Back
6. Done
Now I don't have this problem
Signal an Internet running great.
Maybe it's caused by inability to talk correctly with closest mobile station, does this happen everywhere you are or just at a certain place or country? Same with different operator/SIM-card? I'm not having these problems here in Sweden using Vimla/Telenor as operator (unless I of course step into a bunker ?)

I'm in Romania and using Telekom as operator. I've checked that the LTE bands that the operator uses are supported by the phone. I would get the signal drops even when having full reception. For now I've tried setting LTE only as suggested above, and am currently waiting to see if the issue persists.
I was able to resolve this matter. It was down to incorrect network settings (APN and such). It turned out my mobile operator didn't have the right defaults for OnePlus. I called them, entered manually the settings they gave me and the disconnects stopped.

Are you guys having this issue on OOS or on LOS Roms? Any Los ROM I try, my signal bar seems to fluctuate. Doesn't seem to cause a drop in data, but it does drive me insane

That's normal and caused both by external factors like the cell towers and their power management, and also by the phones chipset/radio power management. Having maximum signal strength at all time would cause extreme battery drainage on the phone.

Yes, but it's not normal for on Los my signal to disappear. On OOS, my signal bar is always solid white, on LOS I can have LTE, and then the signal bar will grey out. Pretty sure it's ROM related since it only happens on LOS

Then it's probably a bug in some subroutine, yes. Not much we can do about it, other than hope someone discovers the fault in the source code, probably somewhere in the RIL integration code.

This is not about poor signal, it's about losing signal completely, like going from full to none instantly, and the inability to access the internet or make a call for a few seconds.
You're right, that sounds more like the RIL crashing and restoring itself.
I've tried all tips and tricks mentioned in this thread but the problem persists. I'll send the phone for repairs.
I had the same - going from full bars to grey and back in 20 seconds. None of the repairs worked, it was down to network settings causing some recycle process every 2 hours or so.

For anybody still having such problems, I got my issue fixed in the end also. It was a network-related but not caused by wrong APN settings. I filed a complaint to my operator and after whatever magic they did there, I didn't encounter this issue anymore.

I've had this on all CM/LOS roms on all my OnePlus phones and Samsung phones. I've been complaining about it for such a long time but no one cares or blames the carrier.
I just stick to the original os now as I cannot rely on my phone if it constantly drops signal.
I think it has to do with the way LOS interprets the signal detail from the chip vs OOS.

Question S21 Ultra 5G - SM-G998B - Exynos - Problems with mobile data and signal.

Hi, I have an S21 Ultra 5G, (SM-G998B), the software update is up to date, and for a few days, I started to encounter various problems, sometimes I lose the signal altogether, I can't call, and I can't be called, I receive a message after 10 minutes that I have some missed calls, other times my mobile data does not work, it is set to 5G / 4G / 3G / 2G, I switch to 4G / 3G / 2G and it recovers for a while, then again to 5G / 4G / 3G / 2G when it has problems, to recover.
I thought it was because of the card, but it's not because of it, I changed it, and it still does.
I don't know what else to do, has anyone encountered this problem?
Thank you!
I assume that you compared with another phone at the same location, etc.
Also, get Network Signal to check what levels is the phone reporting.
If you see very low signal levels ONLY on this phone, a trip to the Samsung rep is probably needed as the modem might be fubar.
I have an open case with EE over the fact my Samsung gets 0-1 bar in what they claim is Excellent coverage indoor and outside. My son (PIxel) and daughter (iPhone) have a good signal so I'm wondering if the S21 Ultra has a signal issue.

Do you have better 5G reception? I had similar problem with 5G reception as my provider still working on expanding it. I am running on 4G for now.
I'm avoiding 5G for now as battery drain is worse having to keep two networks connected. 5G is data only so the phone has to keep a 4G connection for calls/texts and 5G for data.
I have followed EE's instructions: Reset network settings, remove clean SIM, airplane mode on/off, connect to the wrong network and connect back to EE. None of helped
I have the same problem as you. Any solution? I have s21 ultra exynos.
I have since spoken to an EE network engineer about my problem with the signal strength on my phone. So I opened a case due to being in an excellent coverage area but always having a 0-1 bar signal. They did various checks and reported back that everything was fine. I still had a low signal outside with a mast just up the road so they raised it up to an engineer to talk to me. He gave a better answer to my problem, I was near a mast and should have excellent cover. But years after the mast was installed Aldi opened a massive distribution centre right next to the mast and he said the number of phones connecting to the mast was very high thus reducing the signal quality. They are upgrading the mast to 5G so that should improve the situation for me. My original thought was the phone aerial was not up to much but after checking with others in the street they had the same signal problem. So it was Aldi's fault
Signal on my S21 Ultra is fantastic, Vodafone UK. I'm on Vodafone with my work iPhone Xs and the S21 Ultra always has at least one bar more.
I anticipate that you in comparison with some other smartphone at the equal place, and so forth.
Also, get network sign to check what degrees is the smartphone reporting.

If you see very low sign tiers best on this smartphone, a ride to the Samsung rep is probably needed because the modem might be fubar.
I have signal issues with EE too with s21U. Never had problems in VODAFONE UK. Glad that it is not just me on this boat.
Do let me know if any of you guys sort out this. I know it is not to do with our devices, it might be to do with a config issue either at our or their end.

I'm sorry that you have problems with your device, but do you know most people? The vast majority of people who bought this phone, doesn't face any issues with the signal, so they don't go to post on forums about it. There is always that loud minority who think that everyone has this problem, just because they have it.
And it's "you're", not "your".

Question Benefits of the Samsung 5300g modem over the Samsung 5123 modem?

I had poor signal and stability with the Samsung 5123 modem in the Pixel 6, and the updates never solved my issues with mobile network standby using about 30% of battery charge. I anticipated significant improvement with the Samsung 5300g modem. I've only tested my sim briefly, finding signal strength is virtually the same. Does anyone know whether signal strength would be expected to be unchanged, and it is only the stability that is supposed to have improved?

no there is definitely an improvement...My data is much more stable now, in spot where it ussually lag, and 5G is much stronger, less drop to LTE.

Definitely a change from my p6p, my p7 just works now, no signal drops and seems to be stronger, reliable now, I still have my p6p, so later I might run a few tests to check strength and speed
