This there a way on the Nexus 4 to stop the phone from connecting to particular mobile network cells?
As can be seen in the screenshot entitled cells.jpg, I can pick up eight cell sites at my home location, however one or two of them are very slow (<1mbps and high pings), yet some of the other sites are very fast (see speed test attached). Obviously the quickest way is for the network to fix the fault, however since the issue has been on-going for a quite some time, I'm thinking that I should take some action myself!
As I am a heavy data user, I'm not too bothered about cell handovers and such (and I'm willing to accept a dropped call - if need be), but is there a way I can force the phone not to connect to cells with particular IDs?
Many thanks.
We have many different devices here... Galaxy S2, Note 8, S3, Note II , S4 etc... Over the past few weeks we have had our Galaxy S4's start to run jittery, frequently begin displaying a message, "Can't play video" when attempting to play video loops in VideoView and random crashes/device reboots throughout the day. The strange thing was that we had many different S4's that mostly appeared to reboot at the exact same time. It also seemed like at about 4pm every day all of the issues would go away and return the next morning. It really had us banging our heads off a wall since this was effecting so many devices, however only S4's.
Eventually we found out what seems to be going on, although we are still unsure of why it is happening or why the other devices aren't seeing the same symptoms. We are convinced that this is two issue acting together... One with our network and the other with the S4 device itself.
We downloaded the app SystemPanelLite which shows us inbound and outbound network traffic as well as cpu usage. We ran numerous tests on many different networks and what we found was when we were our main company network the inbound traffic on EVERY device would constantly spike from 2.2mb/s - 3.2 mb/s which would cause the cpu to jump to high levels. We put a VideoView on a loop on one device, and on another device we would watch the inbound traffic on the network. Whenever the traffic would spike the video would start getting very jittery and even sometimes throw an OnError event with a what parameter of -1(Error unknown). Eventually if the traffic spiked high enough the device would simply crash and reboot. Occasionally we'd see the inbound traffic fall to 12kb/s and all devices would start functioning perfectly. We have a few developer S4's and we even have a few employees with consumer S4's who reported the issue of their devices rebooting when on the company network.
So we were seeing this traffic on ALL of our devices yet it would only cause the S4's to behave this way.
So I have a few questions:
A) What the heck on our network could be broadcasting in such a way that all android devices would be receiving so much data.
B) How could network data literally crash an entire android system? The system should be protected from such things. (this leads me to believe there is currently an undiscovered bug in a recent software update for the S4, since even my S2 seems to gracefully handle these network spiked without a hitch.)
I'd love to try and set up a test bed to duplicate this issue on a network but I literally have no idea what could possibly be broadcasting in such a way that would cause all android devices to accept such a huge amount of inbound traffic. Any insight into what could be going on here would be very much appreciated!
Thanks for your time!

So we've actually found that there is a device on our network that is blasting crazy amounts of "Neighbour Advertisement" packets. We've tracked it to an iOS device but are unsure who's it is. Anyway, network traffic should not be able to completely crash devices into a reboot state, not too mention the amount of battery is being used simply by having the device on the network. This seems like a pretty big security flaw to me.

I would start by changing your WiFi keys, that should prevent the traffic. Then - before granting access to WiFi via the new key - All devices should be checked for Malware and anti Malware installed.
This traffic is a warning - what if it was a virus that the iOS device was transmitting?

We have actually found out that it was instances of Hyper-V reacting badly together and sending out these packets due to the bug here: [grrr... apparently I'm not allowed to post links as a new user]
Regardless network traffic should not be capable of fully bringing down an Android System. All other devices even as old as the S2 did not crash under this load, why does the S4?
Hello. First, great forum- I can feel the love, as well as the collective genius at work here. It's refreshing to find a forum where people actually know their sh*t on a real, technologically advanced level. It's relieving as well, considering the headache that my new G2 is causing... as follows:
This is a Sprint device and I am still within the time frame to return if a resolution is not found.
Issue:
1.) While wi-fi remains connected (doesn't drop), it is terribly slow, averaging .8 - 3 mbps. Whereas, other Samsung android devices are averaging 15-20 mbps. Internet is cable, and I have reset the modem without experiencing any performance increase. (technicolor TC8305C, bgn)
2.) 4g is no better, averaging a mind boggling .5 mbps. (Don't even get me started on 3g- .1-.3 mbps)
3.) If 4g is even able to connect, which is rare... it disappears and and is nowhere to be found, or be (re) enabled.
Attempted (unsuccessful resolutions):
1.) Performed Sprint recommended troubleshooting techniques:
a.) updated profile
b.) soft reset(s)
c.) hard resets- multiple
2.) contacted customer care: received "refreshers," and was walked through numerous settings and performed various resets.
Recommended CC resolution: return device for exchange.
3.) Sprint store attempted to identify problem, and in the process found that their demo, along with employee handsets (G2) as well as new unboxed versions had the same problem. They offered to switch to an S4 or Nexus5 for free, or wait a couple days to see if the LG rep could offer a fix.
(further) Resolution: pending
Here's the deal- I think we can all agree that this phone is kick ass. Therefore, I would rather not switch, as I enjoy the experience it provides, as well as the satisfaction of getting to really bond with a device when troubleshooting them. Though, this phone seems to be pretty 'buggy,' and while I don't mind tinkering with computing devices (been seeing the blue screen since win '95), I'm not sure I want to be dealing with the potential hassle with a device we all rely on day in and day out to be our life blood... plus, just because I don't see/haven't experienced the other issues others have, doesn't mean they won't potentially manifest down the road. :/ Maybe the Nexus 5 is the better choice... but it seems like cost cutting has taken place in a couple areas- battery (2300), and the camera. Almost like the G2 is the flagship and the other is mildly scaled down in certain aspects even though the end result is compelling for both.
Please know that I am scouring middle earth low and wide for resolutions, and have not composed this post without first looking and becoming familiar with other peoples similiar experiences. I will continue to fact find, and I apologize for not reading all related threads before posting, but time is of the nigh, as I am still within a time frame to return in case the problem is inherent to this specific device (a lemon). Plus, I don't quite understand everything you're talking about, as I've never had/chosen to dig that deep into the obscure settings and techniques I've seen listed (and also because I JUST got it) Hence, the user name- g2 n00b.
So thank you in advance for your time in helping with this. It is both greatly appreciated, and not without gratitude on my part. Also, I hope I displayed proper educate by formating this post in a manner which is easy to sort through. K. let the trouble shooting begin.
also, to the mods- sorry if this is thread/issue has already been covered elsewhere. I also posted this issue on another board and nobody had heard of this problem, so I am fairly confident that i may be justified in having poted this. However, feel free to delete/lock/merge/ if I just didn't see it.. but please provide the link so I can further fact find, because I'm stumped. Thanks.
I just did a speedtest on mine (Also on Sprint) using Wifi.
Same speeds I get on my PC.
It's an oddball suggestion but did you disable the Sprint connection optimizer?
Optimizer enabled. Though, I have tried disabling it and running diagnostics to no effect- doesn't matter what I do, it still won't exceed 3mbps, unless I am lucky enough to receive 4g in certain areas.. then it's a 'blazing' 3.5mbps, but usually .8. I have msl code and have adjusted band priorities and still no difference there, including ##72786 to reset default connections to make sure nothing was adversely affected after investigating the issue.
I'm really bummed. I love this phone. I feel like everything I felt I was missing in the S3/S4 are present here. Love the interface, form factor and all of the settings. Maybe I should take Sprint up on there offer to get an S4 a Nexus 5, but I REALLY don't want to go back to caveman battery hog status on the S4 and have to purchase a backup. I imagine the N5 is more efficient in this area, but it still has a 2300 battery vs 3000 in the G2. Needless to say, I'm frustrated and confused.. but often times, such is life.
Any thoughts on the N5, or suggestions to further trouble shoot are greatly appreciated and welcome?
I have disable the connection optimizer and have done this http://forum.xda-developers.com/showpost.php?p=47423537&postcount=1
The only other idea I have is hit up a coffee shop and due a speed test on their wifi.
The sprint stores by me have crappy wifi speed hence the coffee shop.
I seem to have mostly resolved the issue. I switched channels and encryption protocol. Apparently, my g2 didn't appreciate AES very much. Has anyone else seen performance differences with their device when comparing AES to TKIP? If so, are they drastic? I would think AES would be fine with the g2, considering how advanced it is. I consider it to be somewhat unfortunate if I am forced to select TKIP just so I can get a decent connection. That is, unless of course there are settings I can alter in the ##data# screen that can make better use of this encryption. Is there anything I can do now that I have narrowed down the culprit?

What wireless router are you using? I use a D-Link at home and my G2 kept connecting and disconnecting repeatedly. I was able to fix the problem by updating the router's firmware to the latest version. We've never had any problems with other wifi devices on our router, so it seems the G2 has some unique peculiarities WRT wifi.
I'm running AES with no issues, but noticed following.
LG (Sprint) connects first with a slow 72mbps and switches after a while to a faster speed of 433mbps
I have an Asus Router RT-AC66R, if I play around on the router with Frequencies or the wireless mode, LG would go down to a slow speed.
Don't have Optimizer enabled.
I suspect your problem is a router problem and not the phone.
Hello,
I have a Moto X pure purchased a little less than a year ago, and I noticed an issue with 5GHz WiFi speed.
In particular whenever connected to any 5GHz AP the connection is established but almost no traffic goes through (speed test shows it crawling, especially in upload, and it is completely unusable)
Connectivity over 2.4GHz WiFi and LTE works perfectly, so it does not appear to be an issue due to radio/modems
The phone was unlocked to gain root access, has been used on Official Motorola ROMs almost all of the times, with one single LineageOS test to confirm if the issue is related to Mororola radio/modem or if it appears to be hardware in nature.
Given the fact that the same exact result is present with LineageOS, I contacted Motorola support, in order to request a repair.
I am aware that by unlocking the phone I voided the warranty (even though I have heard of several users in this forum that were able to have the phone repaired/replaced free of charge after the unlock), but in my specific case the support rep stated explicitlkly that Motorola would not service the phone at all:
"Dyril: Yes. Once you unlock the boot loader of your device, we can no longer process a repair for it. You may refer to this link h t t p s://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a for the disclaimer before unlocking the bootloader. " (URL edited to allow the post.. . but is the default disclaimer before unlock)
The disclaimer in particular mentions the warranty being voided, but that page does not include any statement indicating the fact that Motorola would refuse to service the phone even at a cost (I asked in the chat if there would be a cost for the repair given the voided warranty)
Does anyone have any direct experience or contact that could help me on this matter?
Should I proceed with a repair request directly, ignoring the support chat?
Thanks
Luca Rizzo
I Donno worst case they reject it the unlocked bootloader was supposed to void warranty with the exception of hardware if there is a defect in the hardware.... But I would try loading a full factory OTA image one that would have any modem updates...

the issue was present with every ROM I tried, I tested all official full factory ROMs from Android 5.x to 6.0 and also LineageOS too, but issue was present all of the times, suggesting that it would be an actual HW issue, so hopefully still covered
Unlocked bootloader voids warranty, period, regardless of issue or cause (except EU)... I still have a tough time believing this is a hardware issue though, 5Ghz is finicky, and it uses the same antenna as 2.4Ghz in this device as far as I know.

I understand the warranty is voided, but as mentioned in the initial post I also asked if the phone could be repaired at a cost, and their complete refusal would be the issue and also surprising.
As far as the issue being software caused (drivers/radio, rom) could you suggest any additional kind of test I could perform?
I reflashed the phone multiple times using fastboot/mfastboot using all of the moto x pure roms I could find on xda-dev and dload from motorola support site, and also tried the latest LineageOS nightly (that might possibly be using different drivers/radios)
I agree that the fact that the 2.4 is working properly would suggest that the antenna is functional, but from what I gathered from h t t p s://forum.xda-developers.com/moto-x-style/help/moto-x-xt1575-wheres-antenna-t3338080 there are actually different antennas for the different bands (thing that would make sense due to the physical size requirements to optimize reception on the different frequencies) so that might explain why one band works and the other does not
In my experience, 5GHz is sometimes problematic on all of my devices. Unfortunately this seems to be a very common issue. The 5GHz band is well known to have issues with range when it has to go through walls, even a single wall.
Is your router right next to a television or other electronic device? If they are working on 5GHz (not necessarily connected to your router), then they could be interfering. Not saying this is the issue, but just an idea to look into.
The issue presents itself even close to the router, and testing with a Galaxy S4 or a Nexus 7 2013 from the same exact position allows me to reach speeds of 100+Mbps, while the Moto X Pure crawls, and the same behavior is experienced with different routers/APs even of enterprise level.
Do you have any suggestion on possible tests or ROMs/modem radios to flash to confirm it is not a software issue in any way?
Sounds like a H/W issue to me. I have had zero issues connecting to 5Ghz WiFi at my house.
Hey @kattolo
I have some issues when connecting with my phone to a D-Link DIR-822 on 5Ghz, but no problem at all with my TP-Link Archer C9.
I'm not sure exactly why, but i tested on the same place, just placed the D-Link one, try it, bunch of problems in 5Ghz (none in 2.4Ghz network), took it off, replaced with the C9, it always gave me much better speed, connection reliability and range.
Try with other equipment (routers) that can provide you 5Ghz networks, just to be sure it's your phone and not the emitter.
Obs: sorry for any english mistake, not my main language

Mine is a XT1581, the Chinese versio of Moto X Force. No matter it's stock ROM 5.1 or 6.0.1 EU, the problem only occurs on 5Ghz wifi. I've tested it with my home router, a old Netgear 802.11n device with 5Ghz band maxing 300mbps, and also tested it in my office with multiple AC routers supporting up to 866mbps.
My phone connects smoothly with those 5Ghz wifi, showing the wifi logo on the notification area on top of screen. But once I run speedtest app or browing the web, almost within seconds, the wifi traffic drops to zero, then even the wifi logo is still on, in Setting--WLAN, the phone starts searching for wifi signals but eventually to no avail. So I'll have to manually turn off wifi switch and then on again to connect to the 5Ghz wifi, and the loop goes on.
An interesting point I've found is that, when the 5Ghz link speed between my phone and the router is somewhat lower, it works fine, with almost no wifi disconnecting or drops. For example, my home router supports max speed 300mbps on 5Ghz, and if I manually set the router's link mode to 130mbps, my phone works good. In my office, I occasionally discovered that if the link speed is like 173mpbs when the phone is connecting to a certain AC router, no problem at all with 5Ghz wifi.
I guess I've tried messing with every possible parameters in /system/ect/wifi/WCNSS_Qcom_cfg.ini, but no luck at all.
As I said earlier, no problem for me with the Archer C9 (I'm 8 ~ 10 meters away from the router in straight line, 2 rooms far from where it was placed)
Title pretty much covers it.....I have had it with the WiFi issues on the OP8 Pro and was going to go back to the OP7 Pro.
....but people are saying that they are all fixed in Android 11 beta on the OnePlus forums...is this true? And what about Dual SIM which I also need on occasion?
If I move to A11 OB2, can I root and get GPay working?
Is it stable enough to be a daily driver?
Many thanks in advance...

You can root OB2 device, and the OB2 seems usable and also stable enough for daily usage.
I recently acquired a oneplus 8 pro purchased directly from oneplus.com. I have model IN2025. It is the 12gig ram 256 gig storage version. I also have a samsung active watch 2 which I again have had no problems with my oneplus 7 pro. When I initially acquired it, I tried using it with the android 10 non beta firmware. I had multitude of issues up to and including:
1. high difficulty (to not at all) connecting to either my 2.4ghz wifi network OR my 5ghz network. It would state connecting however stall at obtaining IP address. No other devices have issues connecting to either networks including my older oneplus 7 pro.
2. if it would finally connect, while it may state that the 5ghz is connected at 300mbps or the 2.4ghz connected at 144mbps, with random speed tests I would not experience anywheres near those speeds (my ISP dishes out 200mbps). at most I would get 30mbps on my downstream....again if it even worked.
3. both the 2.4ghz and 5ghz networks would often disconnect and never reconnect if and when they did successfully reconnect
I installed the open beta 1 and then did OTA to open beta 2. This has helped quite a bit HOWEVER I've experienced the following issues:
1. while I have no longer received the locking up on obtaining ip address, even if it states I'm connected to my wifi (either the 2.4 or 5ghz) the network is still extremely slow
2. sometimes the device while connected to either wifi network will appear to not send any information aka stall which potentially makes using google messages over wifi unreliable as well aka text msgs show up late etc
In both pre and after beta installation 5g has been significantly slower than 4g cellular data(though I can't say much to that as more than likely the 4g in my area has towers closer near by). Also while on 4g or 5g cellular connections I have though not as frequently experienced data stalls.
Things that have helped resolve some of my issues:
1. this I believe is the largest potential bandage: make sure use device mac address NOT RANDOM is selected. After having done that my connecting to the internet appears to be better (even if it still stalls out)
2. while I've not tried it alot as I use bluetooth alot (with the watch I have and my car and wireless headsets)I've read that turning off bluetooth can help both wifi and cellular data issues
I am currently in the process with oneplus of returning the 8 pro for a new 8 pro as I have not owned/had the phone for greater than 15 days. If that does not resolve the issue, I too may go back to a oneplus 7 pro...or perhaps the 'dark side' and go the samsung route.

Excessiveidling,
This is exactly the type of info I was looking for. So it sounds like it is better, but still bizzare WiFi issues that no other phone on the market has. My situation is...
I have to leave bluetooth on because of watch and hearing aids
I need to rely on WiFI calling on occasion and need it to be 100% reliable.
I need working WiFi at home because I use my phone for some applications that connect via my home network, so having WiFi work "most but not all" of the time is a deal breaker.
So at this point I think I am going to switch back.
I've been a loyal OP fan for quite a while (4 phones now), this has been really disappointing. I even bought a new router because someone said WPA3 would help...but it didn't.
MW
While I can not say anything to the validity of the following statement...I have heard in other forums that the samsung devices with the same qualcomm chipset had wifi/cellular issues (especially with 5g).....that was only ONE forum post however unlike the multitudes of forum posts I've seen regarding the oneplus.
If I were to guess, only based upon my limited modding experiences with previous android phones, an updated modem/chipset software COULD resolve these issues...further more a different/modified kernel as well. Doing that would probably void any warranty though and for spending 800+ on a phone, you shouldn't have to modify in order for it to work just as well if not better than an older phone.
I'll let ya know how the exchange goes. I'm willing to give them another shot 1. because of my excellent experience with the 7 pro and 2. because I've seen so many posts, reviews, etc stating the oneplus 8 pro is THE PHONE to have overall.
Thanks,

I read the same thing re - chipset, and agree that is a possibility. The other is a horrible RF design for the BT / WiFi antenna because they crammed in the wireless charging.
But I don't see any of this getting fixed anytime soon. I wonder if the OP8 (non pro) has similar issues -- I didn't check.
Let me know how your new phone works out - an RF HW update or a new batch of chips could change things.
