[OnePlus 5 Questions & Answers] yz999zz:
Thanks for your report.

I don't think they will solve this issue beacause I suspect that it's hardware related.

Did anyone experience this issue also on Oneplus 6?
[OnePlus 5 Questions & Answers] R4dd:
I have send the logfile to op. lets see what they will find out, I could reproduce the issue very accurate, coz it happens for me daily on my way home from work, like 5 minutes no connection, but its showing h+ connection. I really hope that I will get some positive feedback and they are able to find out the root cause.
[OnePlus 5 Questions & Answers] mmxikus:
I have a 5T that works flawlessly with both my Vodafone (Germany) and my Telekom (Germany) SIM Card and a Onplus 6 that doesn't work on H+ on both networks. 4G and 4G+ is good though.
[OnePlus 5 Questions & Answers] mmxikus:
Update: After two days on OOS 5.1.6 the problem seems to be solved for my 1+6.
[OnePlus 5 Questions & Answers] vl111:
Have this problem as well. Ukraine, Kyivstar. H+ or LTE falls to H and hangs all the time.

I tried 3 or 4 latest firmwares - no luck. Including the latest one 5.1.3 firware. The problem persists.
[OnePlus 5 Questions & Answers] freaky2xd:
same here in Austria (T-Mobile, Telekom)

H+ doesn't work most of the time, when it switches to H+ it's worse than with EDGE
[OnePlus 5 Questions & Answers] R4dd:
Hi all,

OP support wrote me that they are working on this case. Perhaps it will help, if some more ppl send the log file to the support.

Hope we will get finally a solution for this, its super annoying :/

[OnePlus 5 Questions & Answers] IlD4nX:
I confirm it work fine for me... Clean flash, with stock kernel, and magisk 16.6.

3. mobile network works finally like it should

sigh I really hope they fix all this stuff finally

[OnePlus 5 Questions & Answers] doomwithdon:
Based on your feedback i updated to ob14 and I can say with high confidence that this issue is still not fixed. At least for me the experience is the same. ?

Did anyone tried to disable fast dormancy on oneplus 5??? So me h+ working fine on bell network which support fast dormancy but its not working on fido network bcuz they dont support this feature. I dont know if any dev willing to try it by editing in build.prop.
[OnePlus 5 Questions & Answers] doomwithdon:
Fast dormancy is disabled by default on the op5
[OnePlus 5 Questions & Answers] eagledipesh:
How to enable it?
[OnePlus 5 Questions & Answers] doomwithdon:
You must esit your build.prop. Google is your friend :)
[OnePlus 5 Questions & Answers] Puddies:
Is this problem not fixed,yet ? I sold my oneplus 5 last year because of this issue and I am considering to buy the oneplus 6t next month.

However, if the problem is still not fixed, I am a bit afraid, that this problem could remain in the 6t.

Does anyone know, if that problem still occurs in the 5t or 6?
[OnePlus 5 Questions & Answers] strongst:
How about to ask this questions(if not asked) in the op5t or op6 thread of where the question could be answered cause the people own this device?
[OnePlus 5 Questions & Answers] Puddies:
I would also like to know, if the issue has been fixed for the OnePlus 5 in the meantime.
[OnePlus 5 Questions & Answers] RogerF81:
Not really, but it seems it depends on your provider, too.
[OnePlus 5 Questions & Answers] strongst:
Yes, that's the main difference: provider and infrastructure. Hence you need to specify in which country and which provider you're using to identify any issues or to compare it at least.
[OnePlus 5 Questions & Answers] .vermilion:
For me the problem isn't fixed. I got disconnections even in custom ROMs so I think it's hardware related.

My boyfriend bought the Oneplus 6 and don't have any network problems!

We are both at T-Mobile Germany.
[OnePlus 5 Questions & Answers] strongst:
Interesting, I don't face any issues on H+ with two t-mobile Germany sim cards :rolleyes:
[OnePlus 5 Questions & Answers] .vermilion:
I'm on congstar and on T-Mobile - on both SIM cards I've got problems with H+ ?
[OnePlus 5 Questions & Answers] strongst:
I have 2 genuine t-mobile sim cards/ business contracts both sim cards are capable of LTE.

Baseband attached.
[OnePlus 5 Questions & Answers] .vermilion:
Too bad I can't see baseband information on my custom Pie ROM...

I have one private contract (congstar) - no LTE functionality. H+ is buggy.

My T-Mobile business SIM is capable of LTE. LTE works perfect, H+ is buggy... ?
[OnePlus 5 Questions & Answers] strongst:
In areas with only H+ both sims are working correctly like on E or LTE
[OnePlus 5 Questions & Answers] .vermilion:
That's pretty awkward. Guess it's some hardware related issue then...?
[OnePlus 5 Questions & Answers] IlD4nX:
I had the issue but to me it's solved since beta 8...both Sim, Tim/Vodafone.
[OnePlus 5 Questions & Answers] Puddies:
Would be interesting, if there is a correlation between the oneplus 5 version (global or international) and having h+ issues.

Do you have the international version (for chinese market, gearbest?) or global version (europe, north america)? And h+ issues or not?
[OnePlus 5 Questions & Answers] strongst:
I have europe version. But would be more interesting to check the baseband versions :D
[OnePlus 5 Questions & Answers] SkUs:
I'm using SK Telecom H+, It disconnects sometimes.

LTE sim was okay.
[OnePlus 5 Questions & Answers] shangxor:
I don't know about 5t and 6, but the issue persists on op5 sadly.

I tried bouygues and orange in France
[OnePlus 5 Questions & Answers] malawichief:
Still persists on the OnePlus 6
[OnePlus 5 Questions & Answers] doomwithdon:
This issue seems to be resolved in the latest h2os beta pie. Have been using for 3 days and face no h+ drops
[OnePlus 5 Questions & Answers] shangxor:
Let's hope it gets ported to stable :)
[OnePlus 5 Questions & Answers] doomwithdon:
Till it does I'll stick to beta :)
[OnePlus 5 Questions & Answers] srikaran:
I am on the H2OS beta as well and the problem does persist. I am based out of India and when I am on 4G, the connection is pretty solid and works very well. In areas where it drops from 4G to H+, it just doesn't work. There is no data transfer happening and pages don't load up and all standard stuff as if there is no connection. The same issues since Day 1 with the OP5 and seem to persist across OSes too. I am going to try changing the network settings to only use 2G/3G in areas where I only get H+ and see if that makes any difference and get back.
[OnePlus 5 Questions & Answers] strongst:
I'm on H2OS beta too and don't face any issues like on all previous OOS roms https://xdaforums.com/oneplus-5/how-to/oneplus-5-issue-h-network-t3658071/post77958517

Baseband version attached
[OnePlus 5 Questions & Answers] shangxor:
I guess this issue is very closely related to the mobile network providers, maybe the different channels being used.

My biggest issue is still the change from 4g to H, each time that network change happens I lose internet connection for way too long. It is so annoying, especially during phone calls...
[OnePlus 5 Questions & Answers] strongst:
That's what I wrote some time ago until it's baseband dependant
[OnePlus 5 Questions & Answers] shangxor:
So the new baseband fixes it ? I mean the h2os beta baseband
[OnePlus 5 Questions & Answers] strongst:
As you can read before I never had any issues with any oos or baseband. Maybe others, that have compared baseband version if they had any issues.
[OnePlus 5 Questions & Answers] doomwithdon:
and the issue persists on O2 OB pie.. Guess im gonna stick to Hydrogen pie till its fixed in o2
[OnePlus 5 Questions & Answers] strongst:
Definitely a provider issue. I have no issues on OB22 like before(T-Mobile).
[OnePlus 5 Questions & Answers] doomwithdon:
Does that mean that the baseband support in the chinese h2os is different from that in o2?
[OnePlus 5 Questions & Answers] strongst:
Attached is my baseband version of OB22, some posts above the baseband from H2OS
[OnePlus 5 Questions & Answers] doomwithdon:
Exactly the same.. Makes no sense..
[OnePlus 5 Questions & Answers] Axelguitt:
edit : tldr : Oneplus 5T has amongst the worst 3G signal on band 900 MHz, study shows

Look at this article : (posted on xda today). It is a study of phone signal in Ireland in 2G and 3G.

https://www.xda-developers.com/report-best-worst-smartphones-call-reception/

[IMG="From the article"]https://www.xda-developers.com/files/2018/12/ComReg-phone-signal-table-4.png[/IMG]

The colums we are interrested in are UMTS 900 and UMTS 2100 :

This study seems to show that the oneplus 6 has from far the worst 3G reception amongst all phones tested on the band 900 MHz, and a below average 3G reception on the 2100 MHz band.

The oneplus 5T (very close to our oneplus 5 in term of hardware) has only been tested in 2G and show below average signal on the GSM 900 band.

My hypothesis is that the oneplus 5 has bad 3G signal, but only on band 900 MHz ( I guess the oneplus 5 and 6 might have similar test results) : it would explain why some of us are reporting issues and some other not.

What do you think about this ?

edit : when you read the whole study, you find that the oneplus 5T only picks up signal in this study when holded on the right hand. And as expected, shows poor reception on 3G 900 MHz
[OnePlus 5 Questions & Answers] Panta1098:
Did this operation and saw I was on TD-SCDMA/WCDMA under the "set preferred network type".

Changed it into LTE/WCDMA and connections seems work well (no hangs). Will try LTE/TD-SCDMA/WCDMA next days.

The setting remains after reboot too.

On google I found that TD-SCDMA it's a chinese network protocol that doesn't work in Europe, I hope that's the problem solution (know that problem starts from a kernel/hw configuration btw).

(sorry for my english if I made mistakes...)
[OnePlus 5 Questions & Answers] tdemileto:
Same problem

I have the exactly same problem that you described, letter by letter. It's so frustating, not everywhere has 4g coverage.:crying:

---------- Post added at 03:47 PM ---------- Previous post was at 03:44 PM ----------

Thi method is still working? No issues after that?
[OnePlus 5 Questions & Answers] gohan040:
Thanx for trying to help but this is not the problem. Like the title says "issue with H+ network" , not 4G. 4G works perfect. In my own country (Netherlands) as other countries I've been the last few months. (Austria,Germany,Belgium,Portugal) But when the phone switches to H+ (in every country) it looks like it gets stuck or throttled somehow. You see a page or video loading the first sec or 2 and then it stops.... Turning on airplane mode for 10sec helps for a short while but the problem comes back. Manually switch to 4ag as the preferred network helps because it don't switch back to H+. But this shouldn't be needed of course.
[OnePlus 5 Questions & Answers] Puddies:

I live in Portugal, and i and my girlfriend have this annoying problem on OP5 Midnight Black and Soft Gold. This is very stupid and make me very very unhappy :crying:

I already change operator and still have same issue. Before, i think that is operator problem, so i change from (NOS) to (MEO) and still the same. Very slow internet on H or H+ and keep freezing with signal max. I will cross fingers and wait for the Oreo Update... If the OnePlus can't fix this problem, i will sell the phone, and will be the last phone i buy to OnePlus. I'm very very mad with this situation!! :mad::mad: :mad: :mad:

Oos 4.5.12 update

Today have a update and say " fixed issue of no 4g+ network in some regions" hope fix h+ too.
[OnePlus 5 Questions & Answers] okiesuparno:
i've update to 4.5.12 the H+ trouble still exist. the only solution I've tried and succeeded is to use 2 sim cards at once.
[OnePlus 5 Questions & Answers] ExterminalPT:
Same operator or different?
[OnePlus 5 Questions & Answers] okiesuparno:
I've tried both (same and different) operators, the result is the same. My h + network connection runs smoothly when both slots are filled with card.sim.
[OnePlus 5 Questions & Answers] yz999zz:
I think it works because when the issue occurs on the first sim it will witch temporarily to the second one.

It's a workaround not acceptable for me beacause I don't want to pay another carrier subscription.

I also tried to insert another sim (an old one not registered anymore) but the issue still occurs.
[OnePlus 5 Questions & Answers] okiesuparno:
it doesn't use mobile data from slot 2 (my primary simcard on slot 2). i'm sure because my prepaid balance doesn't reduce at all, and i set mobile data setting using slot 1 (in my op5) :)
[OnePlus 5 Questions & Answers] Gizmundo:
On call I heard clearly but on the another side it was dead. I had to call again.. is that related what you discuss here? Because I had this more times and it is really annoying me. If I could to have money back for the phone I'll do it.

Of course i have 4G but not all the time.

560€ for this? No thanks, OP never more... Never...
[OnePlus 5 Questions & Answers] Gizmundo:
But at home I have 4g and this happened to me.. or who knows I wasn't checking the network. So if I use 3g only or 2g it should be ok. Have you tried someone? And do you think it is the reason for asking money back?
[OnePlus 5 Questions & Answers] ExterminalPT:
That was normal. For some reason u can have umts for calls and lte for Internet.

Check my print screen. U can have lte and umts at the same time.

If u put only 3G its not a good idea. U will have this problem all the time.

4G is only for data packets, all voice calls will go in 3g. 4G network does not support voice calls (except VoLTE).

I have inserted my wife's sim card as a second sim, but the issue of h+ network unresponsive still happens... Very disappointing situation!

Tomorrow I will install LineageOS and I will report back.
[OnePlus 5 Questions & Answers] mutleyPT:
I've tried lineage and h+ is unstable. Probably is a modem/firmware issue.
[OnePlus 5 Questions & Answers] ExterminalPT:
I've tried 2 sim cards and already have issues. If is problem with modem, it can be fixed with sw?
[OnePlus 5 Questions & Answers] Feedmeeeee:
Yes imo its sw issue cuz there is no problem with 4G
[OnePlus 5 Questions & Answers] ExterminalPT:
I hope that it will be solved in Oreo. But... :confused:

[OnePlus 5 Questions & Answers] yz999zz:
This morning I have this issue also on 4g network! Notice the "!" on the 4G signal. No network at all, I had to switch airplane mode on/off to restore.
[OnePlus 5 Questions & Answers] Feedmeeeee:
İts not related with roms its kernel/modem stuff

No workaround posted works, what can we do? This device is fantastic and I don't want to switch to another brand, but this issue is very very annoying. If it's an hardware bug it's a serious problem, if it's a software one OP must solve it immediately! Is it possible that after 12 releases they aren't aware of this situation?

Hmm. I'm sorry. After this setting i haven't had any kinda issues :rolleyes:

First of all, nothing posting here are solutions. Only OnePlus have the real solution.

But, if u can jump over the problem, its perfect. U can call temporary fix... So, i dont understand ur comment..
