Hi everybody,
It past 2 mounth, more or less, where every rom I flash (aicp, RR, cm13, BlissPop, xost etc) has problem as 3d title says.
Very very long time to take signal (before only few seconds) and when I start running I quickly lost the signal and it goes away for ever.
Does anyone know if there are problems with android or cm13 (all others roms are sons of it)?
Or maybe my mobile has gps problems?
Thank you all
Just got my new Redmi Note 3 Pro (kenzo) last week. Decided to jump onto a custom ROM after using MIUI for a few days. Here's what I've done:
1. Official bootloader unlocked
2. Installed alka TWRP
3. Wipe all partitions
4. Installed CM13 Radios.zip , then installed official CM13 ROM + OpenGapps + SuperSU
Booted into the ROM fine, used it for a few days and everything works well (including fingerprint). Problem is, I keep getting orange/yellow/red signal bars under battery stats. It's not constantly either. If I leave the phone at the same spot, the signal fluctuates between orange and light green constantly. The entire cellular network signal under my battery graph looks like a traffic light.
I'm not using LTE, just standard 3G. I get about -85db to ~91db, which is high. At the same spot on a different phone (also on 3G), I get about -75db (the lower the better). The thing is, on my kenzo, the signal bar is usually full or almost full, so I don't understand why the signal is so bad. So I thought, maybe I just need to flash another radio/modem. I then took the official MIUI 7.x ROM and flashed the NON-HLOS.bin via fastboot, but the result is still the same.
I've tested a different ROM as well, but same result. I don't seem to have any issues with call qualities and battery seems to be OK and unaffected by this. Not sure if it's a bug (unlikely, as I've tested both a CM and AOSP ROM), or perhaps an issue with the modem/radios or more likely a hardware fault with my phone? Someone else reported this issue as well, but apparently it works fine for them on ZephyrOS or something (I haven't tested this).
I must also point out that while I was on stock MIUI, I don't see any bad signals on my phone. It's always green.
Anyone?
Hi, I'm the one who posted it works on Zephyr. But it doesn't, actually. I solved this problem by putting it on airplane mode, waiting ~10secs and the problem stops(mostly, if it didn't, try again). You can check in *#*#4636#*#*, it doesn't drop to -113dBm. I thought it might not drain battery but I'm on ressurection remixed and there's a phone idle drain of about 131mAh.
Hi mate, thanks for your reply.
I've noticed that as well, tried putting it in airplane mode and then back to normal mode, the signal seems to be a lot more stable. My phone has never went to -113dBm though, just averaging high -80dbm ~ -95dbm. I've noticed that if you hold the phone with your left hand, the signal is much better. I think this may be similar to iPhone 4's signalgate issue, where the modem chip/band is sitting at a bad spot that is blocked depending on how you hold the phone. Disappointing to be honest.....but anyway, signal seems to be stable so far on the leaked 5.1 Qualcomm AOSP ROM. Same thing on MIUI.
Update:
BTW, it's not just the phone signal, even GPS is affected as well. When I'm inside buildings, I can't get any GPS signal at all using Device Only. If I select High Accuracy (which uses GPS and WiFi for fetching signals), I can then lock on a signal. In other words, the Device Only option (which solely relies on GPS itself) will fail when I'm inside buildings. This tells me that the chip for fetching phone and GPS signals is either crap, or that Xiaomi has packaged them in a bad layout design or position within the phone. It doesn't matter what ROM I try, the result is the same. Even using apps like FasterGPS (which downloads the gps.conf file for your country) doesn't help.
However, it's not really a big deal. I can get a lock on the GPS signal inside buildings if I use High Accuracy. Once a signal is locked, I can then switch back to Device Only and GPS will continue to work. Also, when I'm outside of the building, I can get a fast lock on using Device Only straight away, so it's not really a problem. It's just that compared to my Galaxy S5 (a 2 year old phone), the Redmi Note 3 doesn't seem much better. I know it's a budget phone, but the specs of the phone should be a lot better than my 2 year old S5.
One last thing I should point out is that the building I'm in isn't a big building with multiple floors. It's actually a small house and I get about -75dbm for my phone signal. So it's not like I'm in a bad spot with no reception. GPS just doesn't work well when you're inside a house/building on this phone.
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.

M also using rr but finding difficult for the networks to stay connected.
Clean flash it a couple of times, I had to do it thrice before getting it correct!

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.
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
Go back original stock rom to resolve your problem....
Solved

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?

Yes. Both sim slots support LTE (but as every phone, not at the same time of course)

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?

No, but I will let the battery change. I can update you if this is successful or not!

Please add me to update.
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.
Hello,
I've noticed a strange thing, that the more my battery discharges (starts at around 75% battery) the more unstable my network signal gets, and i start losing network data. at 100% battery 4g network and signal is quite good, in speedtests i get ~30mbps download and upload speeds. and at around 30% battery and below, i start having only 3g data or even 2g data and those are unstable, i get no connection and cant call/receive calls.
My problem is similair to other problems posted on this forum, but no clear solution was offered. Also, there was mention of this kind of problem on xda and some german forum when battery voltage is below 4.0 v network signal gets unstable
What i have tried:
- Flashed alternate modem files 466d, s26 , 18s etc. (almost all of them),
- tried a lot of different roms, small eui, stock 26s, stock 18s, small7 nougat, lineage os, remix 6.0, aicp etc.... ressurection remix, nougat, by andr68rus, it has 416d modem. I had best results with this rom so far, but quite not there yet (maybe it's because of custom kernel)
- Entered *#*#4636#*#* switched and set band to automatic, american, japan, pcs (all of them ) . no difference
- renewed APN settings. No difference.
-Entered APn settings mannualy
- fastboot erased modemst1/2 - no difference
- tried unlock and locking bands in QTOOL in diagnostic mode (maybe i did something wrong? but i doubt it)
-I have no case on phone, or other materials that could interfere with signal
currently on latest build AOSIP rom by moto9999999
Should i provide somekind additional logs? Please help a bro out i like the le max 2 very much, but the data and signal problems are driving me mad.....
Hey, it sounds like we have the same problem. I have to frequently charge my phone when the battery level goes down to around 70% in order for voice and data continue to work.
Maybe someone with stable network data and signal could tell me what is your battery voltage on different battery charge states? (100% , 75, and maybe 30%)
Using ampere app my battery voltage when 100% is 4.2-4.3V , 75% - 4.0-4.1V and 50% 3.9-4.0 V (this is where network data gets completely unusable)
Well, googled a bit, seems like this is normal behaviour fully charged battery with 4.2V seems to be normal and desireable, and 3V at low battery is normal. So i guess tinkering with the voltages won't save us
here is a catlog with modem filter. Maybe this causes the problem?
it looks like the battery can't get modem info, so it bugs wakelock, and keeps shutting down modem? What command shuts down mobile data, or restricts from going to 4g? when i try to reconnect log says action_any_data_connection_state
Ive tried to spoof battery parameters via terminal command dumpsys battery set status, to cap the status at current state. Unfortunately it didn't work ?
So i guess this is a hardware issue. Im hesitant to change the battery because its so much hassle to open the phone ?
Please share your ideas bros...
It does not make sense to me it's the battery issue. All functions I need work including WiFi that gives me very good connectivity even at 5% battery level (without the charger connected, of course).
Use the paid version of LTE Discovery : https://play.google.com/store/apps/details?id=net.simplyadvanced.ltediscovery its 2 bucks and worth 10 times that amount.
I also tried everything when testing Miui v9 roms and It was widely acknowledged that there is a miui bug when installed on Leeco devices. LTE discovery sorted that issue and it's now my go to program whenever I flash a new rom. ( I haven't researched the specifics of what it does, but it works.)

I doubt it will help. Did you have the same issue as described?
Out of curiosity I bought and installed LTE Discovery. It has the “restart cell radio” function that resets the data connection and you can set loop it e.g. reset the radio every 30 secs.
Short story, it doesn’t help at all.
