Low Jio network coverage on custom Roms - Xiaomi Poco F1 Questions & Answers

Hey all. This is a peculiar one. Bought the Poco a month back and really happy with community and the support.
Got the bootloader unlock and flashed a couple of custom roms including LOS, syberia,omni etc
All was great but only issue i face was low network coverage. No matter whatever i was,i will get 1-2 bars max. With stock room, its full coverage at those places.
Not sure what going on but I'm back to stock.
Will be happy to check if someone has an idea on what's going on.

Probly a difference in the visual representation rather than the actual signal strength in db

I have confirmed the same from the *#4636 menu and see the signal strength is way too less with custom roms

TrickDroid 5.3.0 fixes AT&T LTE signal/speed issues on International based ROM

Just a heads up for the unlucky AT&T HTC One owners that are in particular markets where their LTE speeds and signal are significantly degraded when using International based ROMs - I have verified that the problem has been fixed in the newly released TrickDroid 5.3.0. LTE speeds and signal strength now match the stock AT&T ROM. The signal strength was probably cosmetic, but data speeds are indeed much better.
good to know- i'll re-post this in http://forum.xda-developers.com/showthread.php?t=2245952

Never had a problem with speeds before the release and the "messed up" signal bars wasn't that big of a deal

Good for you. The LTE speed problems on previous International ROMs are well documented on this forum. If you're in a strong signal area, the speeds are fine. If you're in a weaker area, the LTE speeds in the stock ROM were much faster than the previous International ROMs.
edit: I see in your sig that you're a team Venom/TrickDroid beta tester.
Maybe this is a dumb question.
Unlock the bootloader.
Install CWM.
Flash Trickdroid.
Is that correct? Or is there anything else I need to do? I'm coming from Samsung, so I just want to be sure.

There were no problems...
There was a visual display issue. My signal showed 1 or 3 bars. It was always green in my settings, it was never yellow, or absent. I also only had 3 bars when I got a 52mbs down and 28mbs up speedtest while in Austin.
Ya'all just don't know what a visual display issue is.

I had always assumed the signal issue to be cosmetic, but how do you explain the lower data speeds?
Here are my previous comments on the matter I posted in another thread yesterday:
My LTE speeds are consistently lower on International ROMs versus the stock AT&T ROM. I've done quite a bit of testing at various times throughout the day to try to minimize the effects of varying network conditions and such (I've got 2 ROMs that I'll nandroid back and forth between). In areas of strong signal, the LTE speeds are the same between the AT&T and the various 1.29 International ROMs I've tried (ARHD and TrickDroid). However, at my home where I get just an "ok" signal, on the AT&T stock ROM the signal strength is usually 3 bars and my LTE speeds are 10-30 Mb/s. On International ROMs, the signal strength is 1-2 bars (usually 1) and my LTE speeds are almost always under 8 Mb/s. I realize that silly cosmetic signal "bars" are not as good as decibels when discussing signal strength, but using the app Network Signal Info, the signal strength just stays stuck at 85 dBm while connected via LTE, so I don't know what the real signal value is.
I thought there might be a difference in the RIL versions but the AT&T ROM and the International ROMs are all reporting "Qualcomm RIL 1.0" when queried with the getprop command. I checked the APN's and they are the same. I've tried the AT&T stock radio and the radio that came with 1.29.401.13 just for the heck of it and there was no change, then I saw that someone verified on this forum that the radio.img files in these 2 radios were the same and had the same CRC.

I honestly never had any of these, and I've ran 7.0/7.2 of ARHD and I've seen just low bars. My battery was at 10% with 1d 23h time on it, and over 3 hours screen time. I was able to get fine data speeds at home, at work, and downtown Austin. I live on the fringes of austin, about 10-15 miles E of the city, and I work about 5 miles SE of downtown and had signals that were comparable to my One XL. Didn't notice anything switching to ARHD, tbh.

One thing I learned from my HTC Inspire days that seems to have been forgotten around here is that all AT&T markets are not the same. Judging by a couple of posts in this thread, apparently Austin, Springfield and NYC don't have this problem, where as my market (Tulsa) did have the speed problem on International ROMs.
Back when I had my HTC Inspire, running International ROMs would cause my HSPA data speeds to be under 1 MB/s. A lot of other people thought I was crazy because they didn't have the same problem on their Inspires, but a few people did have the problem. After a long thread I created it was finally determined that the "wap.cingular" APN that came on all the international ROMs was the fault, but only in certain markets. In some markets like mine, you had to manually configure a "phone" APN to get full HSPA speeds.
The only reason I brought up the previous paragraph is because apparently a similar situation existed where there was some configuration setting in the HTC One International ROMs that was causing slowdowns in some markets, that apparently got fixed in the new TrickDroid. And history has repeated itself here today, where people come in here saying the problem didn't exist and "ya'all just don't know what a visual display issue is".
I've had no issues with data speeds here in NYC. I get the same speeds on an international ROM as I do on the AT&T ROM. I've been using the pta apn on both.

Noted. Unfortunately that wasn't true in the Tulsa market. Same thing happened on the HTC Inspire two years ago where some markets needed a fix. Unlike the Inspire however, the One fix doesn't seem to be APN related.

Does torxx even claim to have done something to fix the speeds? If he said he did nothing, then I'm guessing it's just placebo.

I wondered why my signal was lower. Hopfully renovate rom does the fixes too.
I personally havent had speed issues w/ international roms,
however I do have some major status bar issues with the new version of trick droid.

Just out of curiosity, seems there is a lot of problems with Aroma on this device. I know lots of Samsung ROM's used it, and lots didn't. Is there a reason most the ROM's use Aroma on this device? Or is it just a convenience thing?

Supposedly the troubles with Aroma are common on phones with 1080 displays. Even though the international HTC One has been out for 2 months (and other 1080 phones even longer), the problem hasn't been fixed yet because the main developer of Aroma doesn't have a 1080 phone to troubleshoot and fix the problem. I imagine that the developers are reluctant to go back to the old method since Aroma makes customization of the installation very easy for end users.

Nope, during my very first ROM flash, Aroma locked up immediately when I hit the first onscreen button. I thought maybe I had a corrupt zip file, but after verifying MD5 then I started checking around and noticed that almost everyone was having Aroma issues. I was surprised because I had been flashing Aroma ROMs for a year on my Galaxy phones with no problems, and then I read about the 1080 problem. If the issue really is related to the 1080 resolution, then chances are the S4 folks will be having problems as well. I've tried all the suggested workarounds with inconsistent results. It really comes down to just retrying the ROM installation over and over again until it gets through to the end of the installation without locking up.

Bad reception

Hi all! First post in the Alpha section... Got my Alpha the other day. And i love all about it. But there is one thing thats gets me wondering. It's the reception. All my previous phones got good reception at home.. i get 1-2 bars. So my question is. Does anybody experience this issue? I have experienced SMS delays and chipped calls.

Look at actual signal strength in dBm. Bars are arbitrary and vary from phone to phone.

It could just be a faulty device... I'll try replacing my sim first. If that's the issue.
If that's not working. I'll have it replaced.
Edit: Had my sim replaced. Still experiencing bad reception. It goes as low as -105dbm... where my z2 had around -70 (same network, same location)... that's bad. Any ideas what I can do to solve this?
Yeah keep me updated - my Alpha also seems to have noticeably weaker reception than my iPhone on 4G (800mhz band).
Hoping its a modem firmware/software power output thing and not a hardware thing.
Same here, looks like the reception is 1-2 bars worse than other phones.
But I have no experience of delayed SMS or failed calls and the speeds on internet is very good.

Signal problems
Hi, I'm on my second Alpha and first sim, I have an alternative sim yet to try but have chated on Twitter with another user who found no improvement with a new sim and changed phones completely. I'm with three. My signal goes completely when I'm sitting with other three users whose phones work fine. I think it's a phone fault and am considering sending it back now.
Hi guys,
I noticed something interesting with my Alpha:
As you, I have a poor signal strength. But when calling someone then the signal bar jump to full force instantly!
Could it be a link with BIG little technology?

Well, for those who have the same problem, I deactivated the 4G. Then the signal strength is better. I made the test: 2 bars with 4G enabled in network settings, full signal when 3G only.
As a possible future Alpha owner, question.
Are you on a USA Network with the Qualcomm Alpha ?
Or in Europe on Exynos Octacore ?

The alpha is my second LTE able phone. Both showed a completely different signal bar reading when using LTE (and checking in lecture, how Signal strength is meassured for GPRS/EDGE/UMTS/LTE it shows, that LTE uses a completely revised scheme to calculate the signal strength)
I haven't made any speed measurements yet, but my feeling is:
(4G) With LTE, even without any highlighted bar i can use internet, webpages load fast, other lookups work.
(3G,3.5G) With H/H+ , and at least 1 bar highlighted, internet works
(2.5G) Edge and at least 1 to two bars, internet is available... three bars are better for it to be worthwhile
(2G) G only - forget it. I'll need 4 bars to surf the web, and i must wait. Chat works if i'm lucky and got at least 1-2 bars.
Apart from that: the signal bars in 2G and 3G show the strength of the signal - but aren't any measure of the quality of the signal. They show anything that sends on the frequency/timeslot of the 2G/3G signal you're receiving. If you've got heavy interferences, you'll get full bars but it all is static.
(Like - in a disco, you've got loud music, and people speaking very loudly to you - that would be full bars, but not the best place to speak to each other....)
I don't understand exactly what the value used by 4G exactly means, but it sounds like it only represents the LTE cell you do want to receive - so it should be more accurate and cutting out the noise somehow
I think you're right ! This is my feeling too. In 4G calls are always perfect for me even with one bar.
In settings we can also have a more accurate highlight on to the signal strength in Db.
Guys this alpha is full of mysteriousness !
I think samsung did it ON purpose.. ! Save battery??
I have weaker signal too.. on iphone 5 is full and i had on my former Honor 6 full as hell..
But I dont konw IF samsung wants to save power by this .. I think it has no much influence as iphone 5 nor Honor 6 had full signal and battery never got down fast.. when I had Honor 6 100% at night it was 98 % in morning..
Another thing with aplha ,when i leave phone in sleep half hour or longer , th emobile network stops and wont come up...
I have to restart phone or turn airplane on ad off.. then H+ or 4G appears..
I have the issue with mobile data too, it seems to also do it when it has been on WiFi for a while and you change to mobile data.
no service
Hey guys,
I have a very bad reception with my Samsung Galaxy Alpha when i'm in the subway in Paris. To be honnest I have no service, no sms, no calls, and for sure no internet...
I can see people using their smartphones inside the subway without problems.
I had an iPhone 4 during 3 years, and didn't have any problem with it when I was in the subway.
I'm using the same phone carrier "Bouygues Telecom"
So what's wrong with this Galaxy Alpha ?

Hey people,
I'm also having connection issues:
When I boot the phone it's working is at should: Switching between 4G/3G/EDGE etc. After a while the connection sort of times out. I can only make emergency calls. It works flawlessly for up to a day, or it can only work for like 5 minutes.
Rebooting the device fixes this temporarily. My service provider (Hi in NL) has already sent me a new simcard which doesn't help. They are now saying I should send it over for repair.
Btw: When i leave it in CDMA only, the problem takes much longer to arise (like a couple of days).
I can see that people who have posted in this thread are having the same issues. I'm wondering if this is firmware or hardware related, as I want avoid sending over my phone. If it IS a firmware bug, sending it over for repair obviously isn't going to fix this.
I have sent an e-mail to Samsung BeNeLux. Like Simona Simmy says, we should all write to Samsung

Poor reception

Hi,
I recently bought a black z5c from handtec and I'm currently using it on US T-Mobile.
I think I have the apn settings set correctly but I'm only getting one bar for LTE here in LA, even outside with no buildings.
HSPA, however, has strong signal. Any recommendations?

I get very good signal with mine. Even with one bar I get good speeds (tested via speedtest).
You can just use the download internet settings under networks/more if you are worry about using the wrong apn settings.

Reception issue or perceived reception
I am having the same issue, but on AT&T. My model is the E5823, black. I have been swapping my sim card back and forth between the z5c and my Nexus 5 and have noticed that the nexus will have full bars of LTE while the z5c will have maybe one bar. More importantly, though--the db reading from the phones are almost exactly the same and the download speeds are very similar as well. So I think this may not be a reception issue in my case, but an issue with how the z5c displays reception vs how the nexus 5 does. The nexus 5 with full bars should having blazing LTE speed. Sadly, both of these phones are giving me barely 3 mb download speeds. I think AT&T may be having an issue in my area but I can't get a customer service rep to acknowledge it.
I hope I'm right--I'm loving this phone despite the terrible (possibly perceived) reception. I have downloaded an app called real signal and it shows a more accurate reading of actual reception and it is confirming my suspicion.

I'm glad to hear that. This was driving me nuts thinking I'd have to return a phone that I imported and eat a 15% restocking fee. It's also really the only small phone I had my eye on once I saw that the Nexus 5X would be just as big as the regular sized Xperia Z5.
I'm experiencing something similar. I think I have 1 less bar of 4G signal in every place compared to my previous phone. But the phone still works great and seems to not drain more battery regarding this.
But the "time without signal %" is considerably lower than before. (Still. This could be just because of the bad 2G/3G signal at home, which is terrible and is improved now).
Also. Im now getting 4G+ signal (I think it's based on CAT 6). But maybe the strength is just the same as with 4G.
One more thing:
I bought my phone in Italy but I'm using it in Spain. Could that be an issue? I dont think so...because in Europe the LTE bands are almost the same everywhere.
Also. What would happen if we disable all other LTE bands from other countries? Could that help?

107 is pretty weak but without having another phone to compare it to it's impossible to say if it's the phone's fault or if you are just somewhere with a bad signal!

I got a Z5 compact and I'm definitely getting poorer reception than my previous phone (2013 Moto X) on AT&T. Not just the display, but I find more calls going to voicemail from my apartment than before.
I think it's just the way sony is translating actual signal strength to bars displayed. On WCDMA it looks correct, but on LTE bars are always low even though reception and signal is fine.

Cellular LTE signal strength on EU A2017G

This is my second ZTE Axon 7 and I've had it for 5 days. I am located in the UK. The first was returned to Amazon UK due to short battery life in early August.
This one was purchased from Amazon Germany.
When I get an LTE/4G signal on my EE UK mobile SIM in my new AXON it can stay connected to 4G for several hours.
This is sitting at the same location in the office where I work, suddenly it then goes straight to slow GSM and stays on it for some time. Then it may go back to 4G after some time.
Whereas the same EE SIM inserted in my OnePlus 2 phone in the same location gives a consistent LTE/4G signal all the time.
Since the AXONi can maintain a 4G signal for several hours surely that implies the 4G reception hardware is OK.
I hope a firmware fix is possible to improve the reception?
No I don't think that this fact alone would mean any problem. All my other phones behaved in similar way in my office. Whether a phone can stay connected to a tower depends not just on the phone. Rather it depends on the provider. For instance if it think that other needs more bandwidth in that moment it can drop you to another tower. I don't know the full details but I know that there is sophisticated logic behind this behavior. On the other hand I don't want to stay that everything is OK with the software in Axon.
This phone has signal strength issues compare the db to another phone you will see it is much worse on Axon 7
People who don't have this problem are still taking the trouble to log in and write a little message telling people who do have the problem that they are imagining it or that all phones have signal issues. The person who told me it was quite normal that my phone was defective when I was asking about other people's experiences has posted quite a few times about this. Why? God knows, maybe nothing good on Netflix in his or her region.
You know, the ones that tell you they get 9 hours screen-on time when your battery drain, that professional photographers think the rubbish camera on such and such a phone is great and that they dropped their phone on concrete from ten feet up and it didn't smash...
Ignore them. I sent mine back because the signal was bad, booting me off LTE and on to Edge far too often. I'll buy it again in a while and see if I get a better one or even sooner if ZTE announces a fixes or admits they had quality control problems with a minority of units
I'm inclined to agree. There is a reception issue at least on some phones. Hard to know if it applies to all phones, with some people finding it good enough. I'm holding out for the next firmware update to see if it is worth buying again.

I have the A2017U on Straight Talk - buy the 99 cent "bring your own phone" sim card from the straight talk website. Once you put the sim card in it update the APN and (I cannot stress this enough) TURN OFF VOLTE in the settings menu. Far and away this is the best phone I have ever had as far as reception goes.

I had weak signal reception issues with VoLTE turned on - I think the phone just wouldn't switch over from LTE to HSPA with VoLTE on. Without it trying to use the VoLTE it switches over just fine. Since I shut off the VoLTE I can't find a spot anywhere I go now with no signal, and I go out into rural areas without reason for coverage in them A LOT. My Zenfone 2 use to lose signal all the time. My Axon 7 never seems to.
I just switched it off I'll shall see how it goes. Hopefully it works better than it did. I would like to stay with AT&T. The extra data is nice.

I was just searching the forums since I just got the phone on vzw and noticed sometimes I'd have no Internet. I'll try turning off volte for now and see if this helps.

On the A2017U it is located in settings - wireless & networks - more. Don't know if it is in the G model (Is it just me or is 99% of the problems with this phone only on the G model?)

I could be mistaken but I seriously think with VoLTE turned on that it only looks for LTE signal - once I shut it off it started working a lot better
i notice it's showing numbers instead of who's calling.. even if u saved your contacts in the phone

Question S23 Ultra - Phone signal poor?

Hello,
What is your experience with the GSM reception of the S23 Ultra? Mine is lower than my previous phone(S20 FE 5G); I don't have 5G in my region atm, and with S20 in my apartment had like 1/4 strength 4G, with S23u I have the 4G sign, but not most of the time it's 0/4 lines of strength, and also when I get a phone call half of the time I get small interruptions and this is annoying.
EDIT : after march update ,signal reception seems a bit better and also the battery.
G...S...M? What's that? (jk lol)
I don't think many of us really bought this phone for strong GSM performance and it's not really a focus of manufacturers either. Have you tried switching carriers?
You are right...but...its a phone first of all,we should have a great signal fir this miney. Its annoying to have poor recetiin at home and ppl make fun at you "omg you git a such expensive phone and Such a poor signal"
For me compare to S22U (Exynos) is a lot of better and little better than Fold 2 - so overall is good (snapdragon here in EU). I work where is poor cellular strenght.
Signal definitely seems worse than my S21U. I live in an area where indoor coverage is poor and I'm having to rely on wifi calling a lot more than I did with my previous handset.
Personally, I have always found Samsung modem and radio reception to be weak compared to OnePlus. The same place my OnePlus 8T can get 4 bars, my s23 Ultra gets 2. At our last apartment, we both ditched our Samsung devices because we got no service in that apartment but has 1-2 usable bars of service with our OnePlus 7 Pro's.
Hi all!Today I noticed my S23 Ultra network signal is poor as many of your phones.Before I had a Pixel 6 Pro but the network signal was much better than this Samsung.I don't know why ,I have 2 network bars or even no one ,then the phone connect through wifi calls!I am living in UK,Lebara network!Thanks

I don't know how but I check the signal reception and during travelling by train to work and is worst with S23U than P6 Pro.I wasn't happy with P6P,some things but the signal was better than Samsung for me!Even now the Wifi calls is connected because I have a poor network signal.
I hardly got any signal at home on my pevious phone (s9+), but all great with s23 ultra, tbh

Maybe a silly question but why do you keep posting screenshots of yourself commenting
Just keep asking and maybe you can answer yourself!
I found opposite. My old 10+ have much worse signal than my 23u. Inside my house i still have 4 bars of 5G.
Very strange. My S23U is night and day better than my P7P was.
Mine is better than Pixel`s I had been using, the pixel 7 pro I was using was horrible, the S23U is way better.
Signal is all over place, wh3n in low 4g reception it falls back to 3g and when im back in well covered 4g+ it will stay at 3g until I flight mode it. Seems even worse than puxrl 6 pro I had.

That sounds like your carrier is the problem and not the device.

My oneplus 8 pro and Pixel 7 pro had no problems at all with the same sim card installed, its just this samsung that drives me crazy
I don't see any difference, and Im in a very low signal zone. Both s23 and op5 didn't loose signal , but 1 bar and no way to make a call.
