I use a X829 4/64 GB and i recently noticed that i DO NOT HAVE ANY MOBILE NETWORK SIGNAL on Sim 1 (no data no calls). The truth is that during the last time i stopped using my le max 2 as my daily phone, so although i flashed many different " eui" roms i did not tried to insert my sim cards in the phone and try make any calls as i had no problem in the past. Yesterday i flashed AICP - Oreo - X2 (very good by the way) and this time i have the same problem with Sim 2. Some members have created similar threads in the past but i did not found any solution. I really wonder if someone here has any idea or any solution

I really appreciate your reply. Thank you. To be honest I already had this in mind but i finally solved the problem after flashing the zip file that andr68rus gave at this post:
https://forum.xda-developers.com/showpost.php?p=71130265&postcount=5
Just to notice that, although i am not totally sure (since i had to use my phone for a long time), i think that the network quality is also better now as i think that i have better signal than before

You used the patch from andr68rus with the Oreo ROM?
Or did you first got back to stock?

I did not went back to stock. I flashed the zip when i was on latest Cuoco92 23s rom (coming from Oreo, as i was trying to find a solution) and then i flashed Oreo again. In both cases i had both sim cards wotking with a better (as i belieeve) network signal than the previous months i used my phone
I had the same problem with my network and the newest cuoco92 rom, but flashing the zip-file of andr68rus seems to have solved the problem! At least at the moment, the networks works again und I also have the feeling, the strength of the connection is much better than ever before!
Update:
The flash somehow only worked shortly. After a day or so, I had the same problem again. No network at all ( (neither data nor for phone calls), although the phone shows good network connetction! Strange.

For testing reasons i'm using the phone continuously for more than two weeks and i have not any problem at all. Considering that the network signal is better either at my home and at my work i believe that the zip from andr68rus made the "miracle". Of course i do not know what the zip file really did after flashing it (and if the better network signal is because of it) but i can "enjoy" the results
can i flash this on oreo

My sim sometimes shows no service when I switch data from 1 sim to another sim. After restart or several times turning on/off then it shows my sim.
Don't know if it's rom related issue or not but I want to try this zip as users reported that it works like magic.
Is it OK to flash?
Thankyou for your response

When you switch data from the one sim to the other it is normal to loose the signal for a while . It happens with every phone but normally the signal "comes" back again in a few seconds. I don't know if the zip will work for your problem but why don't you ask andr68rus "directly"?
So it's normal?
Yup that exact scenario. So if it's normal then I think it's ok.
I have already flashed this zip and now my data works better then ever. I have sent him pm but he didn't reply. Now you already cleared things up for me. Thanks for your response.
Can someone tell me does both sim slots supports LTE or not?
I am wondering if it might be possible, that this data connection issue is related to the battery status of the phone?
At least, with a fully charged battery fresh from the charger (for example in the morning), I typically always have good connection. The same when loading during the day. But then, and after a while without charging I loose connection or it gets more unstable at least.
Did somebody observe something similar?

It "sounds" strange. Personally i never had similar problems nad i think that this is not a common problem
I found that on a German website, the same problem that I observed concerning the network connection and the battery was also reported. For everybody able to read German, you find it here:
https://www.android-hilfe.de/forum/leeco-le-max-2-x820-x821-x822.2715/lte-bricht-zusammen-keine-verbindung-bei-akku-unter-60-mit-netzteil-ok.860971.html
They report that the network works very stable as long as the battery voltage is above 4 V. Once it is lower, the phone loses connection. If this is generally true, then this might be the problem in my case. With the phone coming from the charger, the voltage is about 4.3 V, but relatively quickly if falls below 4 V.
Is this purely a battery problem? Or could maybe some software modifications somehow help?

As mentioned in another thread, I have been experiencing the same problem when the battery level goes down to 70% or less (~4volt) the mobile network indicator still shows good signal but both voice and data stop working ie. cannot make or receive phone calls and no internet connectivity. But as soon as I plug in the charger, everything works perfectly.

Where did you get the radio from?

Works fine for me. Flashed without any problems.
Now to monitor signal strength and battery life.
Strange. I tried three times and one time from bootloader with same error.
Could be because of SPL 2.60? But I think I flashed other radios with it, but I don't remember.
Will investigate it and try a downgrade.

I've SPL 2.60 installed as well but it flashed without any problems. Only thing is you need to manually soft-reset your device after the upgrade reaches 100%. It is a known 'inconvenience' of the latest SPL.

Downloaded it, flashing took less time then usual. GPRS and 3G works fine on T-Mobile in the Netherlands.

ATT - (Washington DC) - 3G
Picks up signal extremely fast, I would say faster than 1.54.07.00. GPRS is also quick, but I believe it comes with the cost of battery. Battery dropped 20% in an hour from regular browsing and couple of phone calls. This is noticeably higher than 1.47x and 1.48x radios.
so far so good in Rogers/Fido networks, I'll come later with details, still under observation
works good on orange israel

Better signal strength and 3g where I used to get strong Edge. I like it much better. I used to think that people were just making things up about one radio being better than another, however this time I can really tell the difference.
Good upgrade from 1.54.07
Hey XDA
I've a problem with my SGSII.
I've tried a lot different roms like CM7, CheckRom, Oxygen, miui to find the perfect rom to fix my battery usage(my phone usally last for MAX 1 day, even on low usage. (Is this normal??, my friend get like 5 days with his SGSII)
Anyway, on pretty much all of the ROMs above I've occurred a problem with my internet connection - When my phone is idle for a while I looser internet connection and then I have to restart my phone to fix it.
Anyone with similar problem?
Is my phone defect?
Any way to fix this?
Thanks in advance.
This is my first thread on XDA, I hope I did it correctly (I've checked out suggested threads btw)
the problem with the internet connection is because of the signal is not resetting itself. You can use signalreset (market) app as a solution otherwise flash a stock firmware ROM from sammobile and see whether the problem is solved!
My Wi Fi stops working the same way too. All I do is that I reconnect WiFi from the notification bar.

I will check out Signalreset asap, however if it just en/disable flightmode I am not sure if it helps. Because when it happened I always try en/disable flightmode, without luck - I have to restart to make it work :-/
Soo... it's a generel failure in some deeper laying hard- or software, that's not dependent of the generel software-version.
I'm starting to hate my phone, as it is loosing connection again and again, but only after updating to KI8_NEE. There has not been ANY problems with KI3_NEE, which worked perfectly and rocksolid - and solved the same problem from the previous versions... KI8 may be smoother, but i prefer stability over this generel failure (there's a lot of generel faults, not just lost data-connection).
If that the case, i'm going to smash this phone, or put KI3 back on it... i have been so happy with it, but after upgrading to KI8 - i'm starting to develop a hate-relationship with it...
My old HTC might be slow - but it is dead-on stable...
After trying the signalreset it still doenst work properly.
Any suggestions?

Hello all.
I've been having a strange thing in my XPS since I've updated (officially) to ICS.
Randomly the data connection simply stops working.
Basicly I've got full signal, the 3G signal is there, but the H stops showing and no connection at all. I never had this problem in GB...
The only solution is to reboot the phone. As soon as I do that is working again, till the next failure.
Any ideas what might be happening? And the web brwosing in ICS is so much slower... In GB is was almost instant, in ICS is... Awfull. Should I go back to GB? None of the new things in ICS really interest me.
There is some reports about this bug,you have to wait for an update or try another firmware.

Same here.
When I leave my home network in the morning I have to reboot my phone because data is not available until reboot.
If later connect to any wireless network the data traffic comes back like always before.
Same is with my home network. If the phone is connected to home network and I force data, it's always working, only the morning is problematic.
I'm using ICS 4.0.4

Same problem here.
It just randomly stop to communicate even if the 3G or H icon is there. A samsung guy told me it may be an incompatibility between the ICS kernel and the modem firmware. No issues while connected to any WIFI.
Fixed with a reboot. Never happened to me with GB.

I would actually agree with what Sony say here, I was away for a few weeks and used a forign SIM card for that duration. Not once did the Data stop working, that included hopping between Wifi, H, 3G, E, etc.. So Maybe it is a SIM issue ? SInce I came back I also updated to the newest ICS release and haven't seen the issue yet.
I have the same problem and it's extremely annoying. I lose data connection after about couple of days. It doesn't make sense that this is a sim problem because GB was fine.
I have ICS 6.1.A.0.453.
Same here, I am sure its not the sim card, comm'on!!!

Is there any rom with no network drop issues.?
The network drops are not consistent. Some people experience them some do not. You can choose any rom and just clean flash it a couple of times until you no longer experience network drops. Also a kernel like Arsenic would help. Personally using RR 7.1.1 with no practically zero network issues.

Sorry to necro, but this actually works? Clean flash multiple times and the random network drop bug that plagues every single oneplus x rom except oxygen will be magically fixed?
I tried flashing multiple time different rom (stock included). Nothing stopped the connection drops. I will try flashing different kernel and see if that makes any different. I hope to solve the issue this way. If anyone has any replicable working solution it would be very appreciated.
I'm using LineageOS from 20171026 and don't experience any bugs or battery drain, except for rare Tristate-Bugs.
I recommend it, but as said; it isn't the same for everyone.
Hello everyone,
I come with a problem that I've been having for two months now: every custom ROM I have installed (unofficial LOS13, LOS14.1, Omni 7.1, RR) has a huge battery drain of about 4-5% per hour in idle state if it's using data. It's 3G HSPA+ with the signal being mostly on the green side, mind you. This is not a problem of the battery itself, because I have switched back to MIUI and the idle battery drain is reasonable (around 2% every three or four hours). It doesn't seem to be a deep sleep problem either, as wakelock detectors have detected the phone in deep sleep and I've even used ForceDoze. I also turn off most sync options by default.
The problem seems to come when I install those ROMs with either GApps or MicroG; the battery stats show Google/MicroG Services making this huge battery drain and it's attributed to it being Mobile Radio Active.
I have tried submitting a bug report to LOS14.1's bug tracker a month and a half ago, but I've got no response at all from the maintainer, only people mentioning they have the same problem. The developer of the Radon kernel also tried to help, but in the end it seemed like this problem may not have to do with the kernel (tried his kernel on MIUI and there was no drain, but I got drain in any Custom ROMs with it, same as any Custom ROM default kernel).
I've tried everything I can think of, but I'm at a loss of what to do. I'd like to stay far away from MIUI, but at the same time I don't want to have to charge my battery every day with a very light usage. Can anyone with some technical knowledge help?
Thanks
EDIT: Should add that I've done the tests with no other app installed besides the default ones plus Open GApps Pico/MicroG.
1% every two hours isn't good either, maybe your carrier doesn't have fast dormancy and that's why you get battery drain. Might be a long shot but worth trying to disable it.
Can't help with how to do it though since I didn't look into it.

Well, MIUI is kinda very bloated, and I'm using dual SIM (GSM connection to the second one), so to me it seems normal it has drain when there's so much stuff waking the device up. Anyway, I'm trying the disabled fast dormancy now on RR, but it seems like the mobile radio is still very active during doze (although it seems to me to be a bit less active than with it on). It's just a bit, but thanks for the help!
I have the exact same problem the standby time for me is great but the battery life is bad when I use my phone (SOT) with or without 3G/4G or wifi on
I'm on RR

I think atm android is reporting play services drain wrongly.
Mine shows play services kept the device awake for 2 hours but GSam shows play services held it for 47 seconds and total is 42 minutes, at least half of it was Bluetooth streaming.
So use GSam and maybe bbs to figure out what's going on and if mobile radio drains too much.

Well, the battery drain is definitely there, and it only happens when I install GApps (Open GApss Pico)/MicroG. Also, I've done these tests with no other app installed, so there's no other possible culprit that I see besides something from the system, which seems to be the case, as I only have the drain in custom ROMs and not official MIUI with Google stuff.

@Nowowo
So I'm one of those which have this exact problem.
So I have two main theories about this problem:
1-I'm beginning to think that this is not related to some kind of bug that is in the custom rom's firmware, but to SOMETHING THAT IS MISSING in every custom rom, in every kernel and in every firmware later than a certain time, that was supposed to always stay in the phone from the factory condition.
This missing thing might be the DRIVERS for the MODEMS that drive the antenna in our cell, that connects to the carriers bands.
2-It might be that our cellular carriers are switching things around (like updating to 4g networks), and since our phone is not compatible with band 20 (800 mHz) our snartphone can't receive 3g as well as before.
So, for starting to organize a real troubleshoot guide for this big problem, we need to start with small steps.
The first maybe to ask each other (the ones who refer to this exact problem) some questions, for clearing the path of trouble shooting:
1-Which is the country where you live (approximately)?
2-What carrier do you have?
3-Have you ever unlocked the phone using the unofficial way?
.Carlocarnev2000: I live in Italy, I have coopvoce carrier (a vitual carrier under TIM networks, which are most powerful here in Italy), I have always unlocked the phone with the official way.
We can stay strong and find a way to solve this!

Well, MIUI is kinda very bloated, and I'm using dual SIM (GSM connection to the second one), so to me it seems normal it has drain when there's so much stuff waking the device up. Anyway, I'm trying the disabled fast dormancy now on RR, but it seems like the mobile radio is still very active during doze (although it seems to me to be a bit less active than with it on). It's just a bit, but thanks for the help!

How did you disable fast dormancy? Can you please share the steps. Thank you

I have tried to disable fast dormancy too... But trust me, it will just reduce your battery drain a bit, but because it's a forced way to make the cell modem to connect always with the same frequencies without changing them. Fast dormancy these days is integrated in every phone and in every firmware, and it is a wide spread technology in all over the world. It is useless to try to disable it.
We need to find why this problem affects our phones.

So I'm one of those which have this exact problem.
So I have two main theories about this problem:
1-I'm beginning to think that this is not related to some kind of bug that is in the custom rom's firmware, but to SOMETHING THAT IS MISSING in every custom rom, in every kernel and in every firmware later than a certain time, that was supposed to always stay in the phone from the factory condition.
This missing thing might be the DRIVERS for the MODEMS that drive the antenna in our cell, that connects to the carriers bands.
2-It might be that our cellular carriers are switching things around (like updating to 4g networks), and since our phone is not compatible with band 20 (800 mHz) our snartphone can't receive 3g as well as before.

I agree with your point 1, maybe Xiaomi added something to their official ROM that custom ROMs are missing. As for 2, that should be a problem only with 4G in Europe, I believe, but it happens to me in 3G with voice over LTE disabled and the connection option being one of those that don't have 4G.
As for the questions, I'm from Western Europe, my carrier uses band 900 for 3G (Orange), which is the only connection I use and my phone has been officially unlocked.

I just edited the build.prop to add a line about it (don't have my phone at hand right now), but in the end it doesn't seem to really help with battery life.

It is definetily the fault of the modem drivers that are baked in every single rom.
It maybe that our modem antenna in our device is different (by version or manufacturer) and that the drivers right for our antenna are missing. @Nowowo @{s3rious}Where did you buy your kenzo's from?
I personally bought it from Gearbest almost a year ago (20/07/2016).
I'm doing some research on the antenna versions...
Oh I forgot to mention, firmware from official roms suck.
That's the one posted in official Los thread too.
I extracted the firmware from a Xiaomi. Eu rom and got a more stable signal, maybe it will solve the drain.

Yeah I think that, since we live in europe, and the developers live in eastern and western countries (like arabia and america), they have totally forgotten our device from europe, and they stopped putting in the right versions of drivers for europe.
@vkass But the point is: since TheStrix's firmware is extracted directly from the xiaomi global developer firmware without any changes.
This all means that the official Xiaomi firmware has forgotten the european users!
So now we have to tell TheStrix to somehow include the firmware from Xiaomi.eu into his version, so that in the future it will be integrated and we will not have the need to flash the one from xiaomi.eu.

I don't think that is the problem. I did one of my installs over a xiaomi.eu ROM and it stayed the same. Also, my signal is practically the same both in MIUI and LOS (as per *#*#4636#*#* phone command). It stays in the green side, don't listen to the signal bar thing because in MIUI it requires less signal strength than on LOS to show a full bar.
If it were something from the bundled firmware, I believe it would affect the official ROM, but it doesn't. I think it is the ROM, that maybe can't make full use of the firmware or is missing something.
As for me, I bought my phone off some aliexpress shop with good rating around 8 months ago.

@Nowowo What I am trying to say is that the signal fluctuaitions are a bad bug that afflicts us european users that try to use custom roms as a whole. And it's because the official miui software lacks the support for europe. In fact now I'm on miui beta (global developer) 7.6.29 and the 3g signal reception is as bad as the one from the custom roms (if not worse).
The only ones that support in some way the our device (kenzo) at a european level is the xiaomi.eu team, in fact there not only the antenna sensitivity is improoved, but also the gps and the compass is optimized for our satellites far better.
What I am trying to say is that the official xiaomi software leaves out on the most important parts such as those said before.
If it isn't at firmware level what is it then?
@vkass I'll try the latest xiaomi.eu firmware.
I bought the device from HonorBuy. So you think that it has something to do with the firmware. Have you seen any improvements after you flashed xiaomi eu firmware?

Now I'm on holiday for one week! When I will be back I will try vkass's firmware and xiaomi.eu firmware and do some tests!
Can you upload those firmwares online, or share the steps how to export them from rom?
