[OnePlus 5 Questions & Answers] Blumdum:
I somehow have the feeling that this problem has something to do with the switching of the networks

I noticed that data works if my device is connected to h+

And goes into standby, to h, after some seconds not using it

Then when i need the data again e.g. browsing through the internet my network switches to h+ and everything is fine

Now i made the observation that sometimes the network does not switch back to h+ and thats the point where data stops working

There has to be some way to fix this issue
[OnePlus 5 Questions & Answers] dlads:
As I said before, I don't get 4G+ anywhere near as often as I used to and it appears to be precisely the same issue as the H+ problem. So it actually was related to this topic.

Either way, as I've said before this issue whether 4G+ or H+ is going to continue, unless there is an update pushed to fix it or a base change, Oreo or otherwise or an updated radio the problem is not going to go away, I have been through every configuration, flashed different modems and different operating systems with different bases (you're welcome by the way) and none have helped either issue, so the problem is here to stay I'm afraid.

Ps: for me the problem appears to be the handover between bands, the software on the phone Vs the modem is trying too hard to be efficient and it's inadvertently shooting itself in the foot in the process. At least that's my theory..

Where are you to create a log, man? I think you are the right person for this as it seems you really know what are you doing with logs and things.
[OnePlus 5 Questions & Answers] dlads:
At this moment in time, everything is scaling perfectly.

4G+ all the time and when not available H and H+ are working.. not even sure what I've changed to be honest.

[OnePlus 5 Questions & Answers] dlads:
just changed to WCMDA only and it's locked on H+ no drop outs, constant signal strength.

Make sure to turn off mobile data after you've made a change to see its effects.

For example me changing from WCDMA only to my normal WCDMA / LTE only allowed LTE mode, turning off data and back on and its now locked to 4G+ which is quicker.

Having same issue on Idea (India), i have even raised a complaint with ISP regarding this, but been a month No solution, seems i found the culprit.

PS: on 4G
[OnePlus 5 Questions & Answers] dlads:
you "have" found the culprit or have not?
[OnePlus 5 Questions & Answers] doomwithdon:
Just do the following to solve your issues

1. Dial *#*#4636#*#* from phone app

2. Go to Phone information

3. Select LTE/WCDMA as preferred network type

Have not faced any issues after this.

Note:. This must be done after every reboot.
[OnePlus 5 Questions & Answers] cspaulding:
After some researches I found that this issue is related to not sufficient maximum power of transmitter (UE Tx Power). When this parameter reaches max 21 dBm, data transfer and receiving calls not working. Herewith signal of operator is good.

I used Network Signal Guru app to trace parameters and Ping with sound.

Also i found that sufficient UE Tx Power is different for diffrent operators.

For me only workaround is to move closer to base station or changing the operator. With another operator at the same location I have this issue 2-3 times a day instead of every 5-10 minutes.
[OnePlus 5 Questions & Answers] Pro4TLZZ:
Is it because oneplus used cheap chips?
[OnePlus 5 Questions & Answers] cspaulding:
Hard to say. Maybe a chip, an antenna, a metal case, a firmware, or something else
[OnePlus 5 Questions & Answers] yz999zz:
Oreo official has been released, did anybody try if the issue is still present?
[OnePlus 5 Questions & Answers] dlads:
I'd say as it's widespread and havign happened to a lot of people that it's a distinct possibility.

In fact I've exhausted all options and although it happens a lot less to me it's still present, bare in mind that these guys (oneplus) are very new to this game with a budget unlike Sammy who have been at it for years and have no ceiling on their budget (yet they still get it wrong lol)

I can live with it tbh
[OnePlus 5 Questions & Answers] doomwithdon:
I don't face the issue at all anymore with the settings i shared.. Which means there is no manufacturing defect in the oneplus 5.
[OnePlus 5 Questions & Answers] dlads:
hmmm in not totally convinced in that, similar to the jelly effect, some have it bad, others don't, I personally can barely see it.

I've never had much of an issue with H+ whereas other people obviously have even when changing settings.

For me the settings I posted have worked for me but just one person being able to eradicate it does not eliminate a bug for the masses.

I had a similar issue with Vodafone carrier in Italy on LTE mode, continuous voice and data networks disconnections only when the screen off and/or phone in deep sleep. I couldn't receive both phone calls and data unless I manually changed to WCDMA mode... Then I switched to TIM provider and the problem has been solved: now both LTE and WCDMA work at their best.
[OnePlus 5 Questions & Answers] d1n0x:
Having issues with HSPA network on Three Austria since I bought this phone. Frequent hangs and timeouts, sometimes the arrows show data is being transferred and nothing actually goes through.

It's not a carrier problem, as it worked perfectly fine on my old Nexus 6P and on several friend's phones on the same carrier. Seriously OnePlus, wtf?

Here @ germany: I'm more then 50% on HSDPA or HSDPA+ and the other half on LTE sometimes EDGE. Using permanent 2 t-mobile sim cards(first for data), roam a lot between several cellphone towers and never had a problem with stock oos 4.5.15 or xXx rom since Oreo.

Would be interesting if you are able to duplicate our findings if you only use one sim.

I'm from germany as well but on O2 (with good reception). Never had a problem with my former Xperia z5c so something is definitely fishy on the opo5.

This is really annoying bug and I don't if this is related, but my friend's using same carrier as me with same mobile data connection. On his OP3T band setting is "LTE/UMTS auto (PRL). I tested same setting on my OP5 and I get no reception nor does it connect to any network.

As mentioned several times, 4G works perfectly fine. Only get-around for this seems to be to upgrade my mobile data to 4G, which is 10€ more a month than my current contract :(

EDiT: I sent a ticket to OnePlus
[OnePlus 5 Questions & Answers] yz999zz:
Anyway, the best method to *MINIMIZE* (not solve) the issue is to put the phone in LTE/UMTS (prl) mode via the *#*#4636#*#* code in dialer. The issue will never be solved by Oneplus, I think.

The issue is only for several people with several providers in several countries. That's maybe why it's not easy to fix by oneplus.

Noticed the same thing months ago. But because I'm 99% of the time on 4G I forgot about it. Atm I'm on holiday in Portugal and when roaming on H+ I have the same problem again. Changed the network manually to MEO 4G and the problem is gone. This is clearly a issue that OnePlus needs to resolve fast. On H+ internet is not usable right now.
[OnePlus 5 Questions & Answers] mutleyPT:
Same problem here. The H+ is very unstable.
[OnePlus 5 Questions & Answers] yubdf:
I'm experiencing the same problem as well on the oneplus 5. My carrier network is T-Mobile EE UK. The H+ data connection is very unstable & unusable. It will work for around 10 seconds and then will stop working for 1 minute. This problem occurs cobstanly in a cycle like a loop and makes internet usage on the device impossible.

I've tested my SIM on the galaxy S4, S5, nexus, Xperia and the H+ mobile data works normally without any problems and I receive fast internet.

Thinking that my device was faulty, I had my oneplus 5 replaced from the store I bought the device from because of H+ mobile data issue. I had the exact same H+ data problem with the brand new replacement device!

I believe the h+ internet problem is a hardware/software issue with the oneplus 5.

I've updated to the new 4.5.11 oxygenOS and I'm still having the same H+ network problem as well. It's still not fixed.
[OnePlus 5 Questions & Answers] timothydonohue:
here's the solution, guys, because i was running into the same problem here in the states.

i'll start with the problem : The IMEI that gets shipped with these phones is not recognized by carriers around the world as being 4G capable, for some reason. SO, when you pop in a sim card, and the carrier tries to provision it, the carrier only recognizes that IMEI as being able to do 3G. so, that's what it sends.

The solution can be done a few ways:

1) Call your carrier (or go into the shop) and have them change the registered IMEI for your SIM to be that of a phone that CAN get 4G, or whatever the equivalent in your country is. For example, I was having a mess of a time trying to get mine to work, and had the guy in the shop change the registered IMEI (what they see) to that of a Galaxy S8 (which works here, not sure about where you are). Pop the SIM into the

right

slot, and it finally worked, after we wrestled with the stupid thing for 45 minutes in shop (and I spent another 30m on the phone with another technician, see below). So, the easiest way to check that is to pop the SIM out of a friend or partner's phone that does have 4G and plop it into your phone, boot it up and check. It did matter on my phone that it had to be in slot 2, for some reason. or at least the one labeled slot 2. I hope you get the picture...

2) Cut down the microSIM from your phone you were using before and just use that, unless you've already deactivated the SIM. There are instructions online. It apparently works too. I won't go into it, but I did cut mine down, but couldn't try the method because my SIM had already been deactivated (long story. I had to spend 30m on the phone with another technician after I left the store yesterday, because it still hadn't gotten 4G on my new nanoSIM, despite changing the IMEI, but that's because the idiot put the card into the wrong slot, and I'm an idiot for not noticing it.)

Any way, hope that helps clear things up.
[OnePlus 5 Questions & Answers] okiesuparno:

There has been some changes in the kernel source code for OOS 5.0.4 for OnePlus 5 /5T :

Seen on GitHub :

"

Synchronize codes for Oxygen 5.0.4 OnePlus5 & 5T

kernel device tree source code for OnePlus 5 & 5T O device

List of Changes: 1. Merge Qualcomm patches.

"

https://github.com/OnePlusOSS/andro...mmit/aa184a7d3c9edf2886be52605c80e352fb34a696

I don't understand the code and what the changes implies but It might have something to do with modem firmware (the changelog says " merge Qualcomm patches", and the OnePlus 5 have a Qualcomm modem I think).

I recently updated to OOS 5.0.4 and I spent the whole day on 3g (France SFR). I had no signal instabilities at all : I used a lot of data, YouTube, web, mail etc.

Do you guys see any improvement with 3g? Does someone understand the changes in the kernel source code?
[OnePlus 5 Questions & Answers] Spider-Vice:
Any changes to the modem would not be listed there. Our processor, the Snapdragon 835 is also made by Qualcomm and that's what they mean - they're kernel patches from Qualcomm, who also make the CPU for the phone.

I noticed that with the latest open beta 6 and 7 the situation is a lot better. Not Perfect though. I have also the suspect that is also related to a carrier problem, because my colleague with his Galaxy S7 edge have the same issue while on H+
[OnePlus 5 Questions & Answers] R4dd:
Im still having this issue, phone almost useless. Network carrier Vodafone Germany. Can´t be that it takes sometimes 5 Minutes to get the connection "back" when it changes from 4g to h+. They cant be serious to expect to turn on/off airplane mode.

Meanwhile a lot ppl have this isseu on oneplus forum too, but no reactions from oneplus.

no camera fix, no project treble, and they dont care that the network is not working...sigh...I really wanna like this phone, but this points confirm to me that this would be my last op phone :(

Update

I wrote to OP customer support. Surprisingly I got an contact to a 2nd level support. I linked the thread from here and he read through our posts and said I need to send him a log file. I also mentioned that another employee said it's the 835 issue and we don't believe that the social produce the issue coz other phones don't have this behaviour.

He said also that it could be possible that they have to optimize some configs for modem or antenna.

Fingers crossed. I will record the logfile today. Maybe anyone wanna join or can provide and old one (gdrive link)

This is what he wrote:"Going back yes, you are correct, we will capture logs for the network behaviour. You may have been informed already about the Snapdragon 835 behaviour but we still can't take away the possibility of having a software or antenna issue. That's why we need to inspect the logs to verify exactly what causes the issue. Here's the steps how to capture logs:

Input *#800# from dialing interface, enter ""oneplus logkit"" enable "Move log path to built-in", tap delete history log

Click ""advanced"" > ""save log type"", enable ""Tcpdump"", then click OK

Click ""save log"", when it informs you whether to reboot, click “cancel”

Click ""get QXDM Log"", choose “modem-common”, roll down, click ""open device log""

Reproduce the issue and take a screenshot to record the time (better above 10 minutes)

Click “save log” again to stop it, enter QXDM Log and choose “close device log”

Enter file manager, choose storage, find the oem_log file, zip it and send it to us along with the screenshots

QXDM log is essential, it's named as diag_logs in oem_log file, and the size should be much larger than normal logs. (Usually above 100MB before zipped). Please delete oem log file from file manager after sharing it to us. If the log file is too large to be attached to this support ticket. You may upload it to any cloud storage like Google Drive, DropBox, etc., and send us the public link.

Kind regards
