Poor data signal - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

I am having really bad data signals here in London , to the point that I might sell and get another phone. I am currently on Syberia Project Rom(Android 10,global firmware).
I am on the Three Network and did not have much problems with my OP 6T , yet with my 9T Pro I get poor data signal in some areas in Central London. I work around London Bridge and have hard time with data signal with 4G and 3G.
Does anyone know what I can do improve this?

Any US users who can tell me about the signal Diamond's getting?

I'm thinking about getting an unlocked Diamond and use it on T-Mobile network in the States, but i heard the Diamond doesn't get good signal strength in the US due to the lack of support of 850 or sth.
I have very very poor signal in my apartment, I only get 1 bar with my Nokia, and that's when I put my phone right beside the window. Anywhere else in the room, nothing.
I just want to know if the tweaks would help me get a good signal strength, at least as good as a Nokia. Thanks!

Radio Recommendation Please

Good Afternoon everyone,
Having great fun with my Touch Diamond and T-mobile :-( Having a few problems to say the least...
Anyway could anyone please recommend the best Radio for picking up the Strongest 3G signal. I don't care to much about battery life or anything I just want the best 3G signal I can get because both my Work Location and Home Location reportdly have a 'Good' 3G network available. I can not get 3G inside a building outside at my work location on good days it picks up or just up the road its fine while other users on T-Mobile get 3G inside and outside the buidling fine and at my home location I have to go out to the beach to get a one or 2 bar signal.
So I am guessing if I go for the best Radio for 3G reception I may get a low signal which will be better than now
Thanks,
Max
the 1.15.25 14 seems to be what you want (good 3G and fast fix gps), I don't use this radio, I tell you what I read here :
http://htc-touch-diamond.forumactif...mond-f5/nouvelle-rom-radio-1152514-t12995.htm
Thanks I will give that one ago, I have also logged a complaint with T-Mobile because they say Good To Very Good 3G strength in my area but we can never get it, on absolty perfect days I might get one bar of 3G on the beach but thats it and its not just my phone there is generally a problem somewhere.
I currently get a full strength GPRS Signal just won't pip over to 3G.
Regards,
Max
There's a good thread over on ppcgeeks.com about this. If you go search for "best radio" in the Diamond forum I'm sure you'll find it. Popular opinion is that it depends on your location. Personally I use the 1.03.03V Good luck!

I've got the same problem here in west london. Only with the p3700, samsung tocco has no prob in picking up H oh thats with vodafone.
Funny Thing:
My problem has just gone. I didnt do anything apart from leave the area and pick up a signal from another mast which gave me the full H. When I returned to west london the area of which I was having the problem, the problem was no more. I get a full H no matter where I am.
I don't understand it's like the phone was given a kick up the backside.
Maybe someone has an idea!!

[Q] O4X Weak Cellular Network Reception (Particularly 3G)?

Hi,
I have my O4X since Feb in India. My room is in corner of my house so reception is generally on weaker side. But I have noticed that my O4X has weaker reception as compared to other phones, even cheaper Chinese android phones get better reception than this.
Coming back to problem, using same network sim in both my O4X and my Xolo (cheap android phone), at same place at same time I get 3 out of 4 bar of reception in Xolo, whereas my O4X shows either no bar or just a single bar out of 5 bars. I tried different operators, different sims but this reception scenario remained same, all are 3G network sims. While on 2G network I don't really see any issue with reception. I am getting insane as to what is causing this issue, I have noticed this thing since day one, with ICS, JB, now I am at CM 10.1.
Is this a common issue with this phone? Does it have weaker radio/reception? Or is it with my handset only? Shall I give it in for repairs? What you guys suggest?
Thanks in advance for all the suggestions that will come my way..
I am from India too. I think you are using any phone cover, maybe. It makes problems. For me it happens. I always remove my phone's cover when using net. Also, there are some network frequency that receives low signal. I am using Reliance 3G. I am in west bengal state. In my house west bengal network works well. In my friend's house kolkata specific signal receiveing is well. Also, in his L5 kolkata network's frequency works out well and in my 4X wb is better. When he came to my house he has no signal reception in wb network but I was using it well and I got to his house I had no signal or bad signal reception in Kolkata network.
In short everything is device specific but our device has better network reception. You can try to set network manually.

I do use a mobile cover, will try it without that. I have used Reliance 3G, Airtel 3G and MTNL 3G all in this phone and generally notice a weaker network as compared to other phones at the same place using same network. I have also noticed lately that generally it gets a normal signal when its kept on bed but as soon as I touch my phone signal drops significantly, sometimes from 3-4 bars to 1 bar immediately. And as soon as I take my hand off of it signal improves.
Well, I am not sure what to do now, will try to use without cover and see. Else it will go for repairs. Only reason I havent sent it for repairs yet is because of unlocked bootloader, will have to relock it and flash to stock before I do. Thanks for the suggestion though.

4G doesn't stay, always return to H+

Hello everyone,
I just bought a Oneplus 3T and it's a really good phone, but i'm facing an issue : 4G only appears a few time (with almost full bars) but it's just coming back to H+ every time, i mean every time.
Usually i have 4G in that place, even with my old ****y Samsung Xcover 3 and its the same with another phone operator sim card.
What do you recommend for me ?
Thank you very much
Details :
French version
Up-to-date (Android 8.0.0)
Phone operator : Sosh (tried B&YOU)
Fix
*#*#4636#*#* use the diagnostic under phone information and move it to 4g/lte only
I've seen this solution but it's not a real one, no ?
If I put LTE Only, i will not have 3G/H/H+ and stuff if there is no 4G around me, right ?
Perhaps your ISP radio tower is far away, doesnt mean its phones fault
I had some issues with sim. I've to get new sim and 4g service reactivated
Well, as i said before, i was able to have 4G even with my old Xcover3 in that place, so it's not the network provider's fault.
4G is working on my Oneplus 3T, it's just that it's most of the time, like MOST, on H+ and not 4G even if I had 4G in thèses places before...
It looks like he phone auto balance between 4G & 3G as soon as 4G is a little bit weak (even weak, it's still beter than 3G anyway...) and I noticed that sometimes the data are just turned down (nothing DL, charge, but H+ still on status bar).
Im on Oreo stock OOS, do you know if there is any issues on this new version ?

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.

Have terrible signal strength everywhere with my s21 ultra
I often find if I cycle airplane mode on and the off again it reconnects to 4g and is less terrible but still find my older mate 20 pro Huawei got much better signal strength everywhere than my brand new Samsung
4G Performance on Exynos S21 Ultra is waaayyy slower than an S10+ or S20+
Hi Has anybody else noticed that the S21 Ultra doesn't seem to deliver consistent and reliable 4G speeds, particularly in terms of 4G uploading. I've done a comparison between my S21 Ultra and a S10+ both on the same network (EE) and the results are shocking. The S21 Ultra simply doesn't...

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.
Has anyone ever found a solution to the abysmal signal strength on this lemon
s21 poor signal strength
I've just upgraded to the s21 from the s10. Problem is that I now only get 1 bar showing on the signal strength most of the time (including home). On the s10 it was on 3 bars most of the time using the same network and SIM. If I swap the SIM card back to the s10 I get 3 bars showing again I...

Haven't faced any signal issues so far. I get fantastic LTE signal on my S21U, same as my wife's OnePlus 6. No issues with call quality or network speed either.
Congrats
I'm guessing your not in an area with iffy coverage then or your just lucky
Most are not
Which is quite evident if you bothered to read any of the thread I posted as an example

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".
