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.
I recently switched from lollipop (slim 5.0) to marshmallow (slimm 1.1).
I noticed that the mobile network signal is not as good as it used to be. What software related things determine the signal strength and can they be tweaked?
I assume all basebands are functional and that the broadcasted signal has not magically reduced I strenght at the exact same time as I upgraded.
Currently I am on Jio 4g roaming in other state. I am facing signal issues. There are frequent drops in signal while it is present on other phones at the same time. Any solutions?
All z1s have this problem. This phone isn't good for remote areas/ the areas with weak signals.
And its jio's poor service too
So nothing can be done?
Yes
Does anyone notices unstable signal bars on this phone? Same spot, same mobile network, my pixel 2 xl gets full bar while xz2 only hover around 1-3 bars.
This may also contribute to mediocre battery life I've been having. My mix 2s (sd845) certainly fares better in that department.
I can only compare it to Z5 on same location(basement,) which had none or 1 bar signal and no lte/4g, now i have 1-2 bars and lte/4g on xz2
I have the same issue. But it's everywhere. Not just in limited areas. Sometimes, I have LTE+ and next thing you know, it just says LTE with full bars but to internet. It's been doing that all day. might need a new SIM so I'm going to T-Mobile today.
Maybe it is a software related problem.
I had the same problem on LineageOS 14.1 and 15.1 on my Nexus 6, too.
i have the same issue with my xz2, the LTE network is unstable , sometime it goes to 1 bar or no HSPA instead of 4g , is it hardware or software issue ?
I've just tested a z3, xz2 and p8 lite 2017.
At home, weak signal sometimes, p8 has 4 bars, z3 3 bars and xz2 jumping between 1 and 2 bars.
At work, strong signal, p8 4 bars again, z3 jumping between 3 and 4 bars, xz2 2 bars and switching between 4g and 3g a lot.
Really hope they sort this.
Actually, my signal have always been pretty stable, coming from Z3. When I say stable, I mean 3 bars at LTE (4G reception in my location is still not that good, this is the location's fault, tbh). I got 1 to 2 bar(s) at LTE with my Z3.
I have noticed the opposite. My XZ2 has more stable 4G than other phones in my household consisting of iphones and samsungs and its way better than my previous xiaomi.
I get the feeling that the XZ2's signal bar is showing the signal quality rather than the signal strength. For example, when I'm in a congested area I can see that in apps like Cellmapper I have a strong signal to the nearby mast, but the signal quality is poor due to the high number of users and interference.
Overall, it is better to show the quality of the signal rather than the strength. Ultimately it's the quality that has the most impact on data speeds.
I have better reception on LTE/4g on the XZ2 than I do on my Nexus 5X, that sits around 2-3 bars and the XZ2 is constantly on 4 bars...so no complaints here ?
Same problem with my XZ2C
I get 2 bars on average on my XZ2 Compact. But it's very jumpy. When i take it out of my pocket it goes from 1 to 2 bars. No problem with other phones.
Signal Quality Issues here too
Have had my XZ2 for a couple of months and yes, signal issues galore. I commute for work on same highway almost every day and know where I would get some signal issues with my previous samsung phone but with sony its everywhere..even when I'm home its unpredictable. Sometimes I just get a voice message indicator but I did not hear it ring at all. I am aware that not all signal issues are the phones fault..the provider also is not perfect at times but I just cant help to compare it with my previous phones (many brands) and Sony falls short in that area... I was very optimistic being a nice top-tier phone, great pictures and video, the included software is not bad either, great sound from internal speakers including a nice display but fails to deliver on its most primal and basic function...voice calls. Will keep waiting for that much awaited OTA upgrade where Sony tends to this signal issue problem. If not, its off to craiglist.
Hello.
I have noticed that mi9 has weak antenna or something is going bad. Previously I was using OnePlus 5t and I haven't noticed any significant battery drain from signal reception. Now in battery stats signal takes most of the time 1st place on the list of battery usage.
I was trying to figure out something with *#*#4636#*#* in dialer but I haven't found anything suspicious other than Sim 2 was even though not used seems like it's trying to connect to antennas.
Any time I am in "2 bars" or less on any of the phones I have had I notice significant battery drain from signal.
That said, the Mi 9 seems to have better signal reception than my roommates old iPhone or her new Pixel 3. There are areas with bad LTE coverage and I can often maintain LTE when she cannot, and I typically have higher cell signal strength.
I have week signal reception on 4G compared with my other devices on the same sim and in cases where I am in spots/places with weak 4G coverage it changes to 3G although my other device remain in 4G.
I have tested against some more devices but always MI 9 is weaker.
I can force it to keep the 4G with "LTE only" option but that's not really a solution.
