[Q] Mate7 4g data problem

Hi all,
I've had this great phone MT7-L09 (softare version L09V100R001C00B127) since last December. My problem is that every now and then the 4g cuts off for a period of ten seconds.
It does not matter how strong the signal is nor which or whatever app I'm using. It just loses network. First thing I did was to change the old sim card to a new one. Did not help.
I was in contact with the Huawei support and conclusion was to send phone to service. OK. It came back with the same problem altough they changed the circuit board...so obviously they though that this would solve the problem. I did not. After messing around with it, trying to find if someone else was suffering with the same problem, with no luck, I send it back to service. Now they said that there is nothing wrong with it, but the problem is still there.
I havent noticed anything cut offs using 3g. It's not a major thing but it would be nice to know if its a firmware or any other software related problem.
If I use Netflix or similar where the data keeps coming it works just fine or if I use the phone as Wi-Fi hotspot, no problems.
It just loses network connection using apps like play store, facebook, whatsapp, twitter, every browser ie. firefox, build in browser, chrome, to name a few.
Should I just keep using it as it is or keep sending it back to service until they fix this issue???
Thanks

Sorry...one stupid question: have you already tried keeping the phone completely stock (without any application and/or software or any kin dof personalisation) for a couple of week and see if the problem still exists?
It really seems to me a software problem. Very strange.

I had the same problem with my MT7-TL10 golden version. For a week or so, the network used to come and go. Then ultimately the sim was not recognized at all. I sent it to Huawei service center and they told me that the sim slot is broken and I had to pay for replacement of the board which I refused. I was sure that I didn't break it. Now I am using my phone with one sim only.

Thanks for your reply,
I haven't used it only with stock apps for a week maybe a day, but first thing when it came back from service for the first time, I did not install any apps and it still lost the connection anyway...

I'm not sure, but isn't the sim card slot located on the circuit board??? If it is, it cannot be the problem, but I must try the second slot anyhow.

Man why everybody blames PHONE first??? like not trusting !
To fix this problem is to go to networks and u have to restore your apn to default it like refreshes then you can either just turn off data and then on and restart phone

Does not work, same problem after a numerous resettings. If I may add, I've have couple of other phones of which this problem does not occur.
In same place and conditions these phones work just fine not losing the data connection. Sure, if 4g is not available they use 3g, but never ever will the connection break off.

faulty 4G module tuner.. phone ... replacement needed...

change preferred network
Go to settings and -->mobile networks-->>preferred network and select "WCDMA only"..
It will fix your problem..

There is no such option in my phone settings, only the option to choose automatic 4g3g2g or automatic 3g2g or 2g, 3g only and 2g only. As previously stated no data loss nor connectivity issues using 3g. It's bit annoying sometimes when phone loses data connection altogether although signal is very strong. Just waiting lollipop upgrade if it'd solve the problem, I doubt it but...

network operator..
I think it's network problem..please contact your network operator..4g network have connection problem from some local area signal towers..so you just put other network company SIM card in your local area..(use 4g supported SIM only)

Thanks for your advice, but I don't think that it's SIM card problem because there is no problem what so ever using my other phone SGS5.

sorry

Hmmm. Sorry friend..I am helpless.. anyway continue your thread here..in Xda have brilliant members..they can help you..best of luck.

Thanks, I totally missed your comment...this is turning out to be quite a puzzle. I've noticed the less battery (<60%) I've have on the phone there seems to be nothing wrong with the 4g connection. ???

To answer to myself, I was too optimistic...nothing to do with battery. It's just so weird that phone works like a charm most of time and then suddenly not. I'm confused...

Now on the newest firmware lollipop 5.1 it fixed my lte problem

same issue
I bought mate 7 a couple of days ago and I keep losing the data connection. the network gets connected and lost again.
i did everything to fix it but no luck. changed sim, restored device, modified APN and no luck.
it keeps disconnecting seems that it is a problem with the phone itself as i have read the same issue on a couple of forums..
hope it is a software issue and get fixed soon as this is annoying.

In service they replaced my phone to a new one mostly because of this problem and I can say it did not help at all. Only upgrading to lollipop will fix the problem ( tested on beta) I'm on b145 now and it does that all the time. I guess it is carrier based problem not SIM nor hardware.

Yall have these Verizon OnePlus 8 issues?

Is anyone else getting freezing using chrome browser? If so what browser do you recommend? I've tried Firefox to and Opera for some reason this phone hates. I don't get why this phone is so slow. Mine takes a minute to process anything. Really hope they fix these software hickups. I guess FR but that would be a big job. The battery consumption seems to be the only best feature on this phone.

Yes, seems like it's a OnePlus problem. No one has a solution that I've seen yet.
I just minimize Chrome and reopen it and it works again.

It's not just on this phone. I just came from the Essential phone and Chrome's been doing that for months. It's Chrome, not the phone. I don't think the built in webview is playing nice with the os. Maybe try Chrome beta?
Question: are you using a custom DNS or VPN?

It's also happening to me, I don't use any VPNs nor DNS. I think this is a OnePlus Problem, maybe they'll address it in the next update. Let's report this problem guys
Edit : I'm not on a Verizon version, mine is IN2010

Funny thing is whenever chrome freezes, going to the home screen and returning back to the app fixes the issue ??*

It's not OnePlus, it's Chrome. Acts the same way on the Essential PH-1. Try Safari or Microsoft Edge browser, or any one that uses Android web view.

The fix is to install another web browser, then go to apps in the settings and inactivate Chrome. Haven't had single hickup since I did this.

Nice. Glad I came across this noticed it instantly when I first got this phone back in April course I couldn't find anything about it then. And oddly it seems like it is way worse and 90htz. Was about to return too vzw. Honestly was thinking it may be a device issue Till I read posts Any suggestions? Gonna try brave

Not really sure where to ask this question but Verizon OnePlus 8 UW. No root or anything outta the norm. Constantly having intermittent data loss, intermittent hotspot loss, calls and texts as well I'm sure since they pushed an update couple weeks back. Message I get from there network troubleshooter says( Your phone can't auto switch too a faster network if it's available. Your better off too use Cdma/Lte or global mode for better signal strength). Far as I know Cdma had been reserved for EMT/Fire etc. Problem seems too arise only when the silly 5g icon comes up. So thinking when it tries too switch too 5g its having that intermittent loss going back to global mode an getting hung up somehow as a simple restart fixes it temporarily. If I was rooted I believe a prl or apn change would fix it maybe. So tired of dealing with Verizon techs, Any help it fix would be great

Sorry ta hear I've done a lot of searching and can't seem to resolve it. Dealing with Verizon it's just getting so old I believe I'm going to just try an root, flash, etc. That or go T-Mobile. If I may ask are you in the States? I'm in Florida btw. Very populated city Clearwater is a big fact and it's a problem all around

I've had Verizon family plan for 20 years now. So I have to deal with it. I remember buying old Galaxy s3 and moding the hell out of it. But I'm older and don't have time like I did when I was younger so I'm stuck. The problems on my OP8 5G UW just accelerated. I'm pretty sure it's software related. Last system update was a "network improvements" haha- yeah right! Since after I've been in hours and hours in Verizon chats, calls, I've spoke to OnePlus techs, I've done replacements, sim swaps, clean resets. Nothing is working to resolve my 1mbps download speed network is slow as hell, 17 Meg's 20 min. Tomorrow I'm talking Verizon tech to get my 4th replacement turned in and hopefully get a Galaxy S10 FE. I always wanted ONEPLUS but not this way. I'm done

I'm in Frederic Michigan, near Grayling. Rural area, but Verizon is king up here. And, with a low population density, I've had really great service for years. Up until recently. Wife has a Galaxy Note 9 and doesn't have half the issues.

So update. I wasn't allowed to move on to another phone with old big red. I exhausted my replacements with Verizon my only option now is to pay this off and move on. I did get some slight improvements turning the automatic to manual in Network Mode. It seems like I don't have the constant 5g/4g fight. As for original topic, I use the Samsung browser and I don't have any hanging or freezing.

Yea I'm kinda and the same boat got a phone didn't work good paid it off early got the OnePlus and now this I did switch to manual too and it helped a little bit. But not a lot we can do I definitely won't be buying any more Vzw phones. I can't even maintain consistent hotspot for over 30 40 minutes ever since past update. I have the 5G icon now that's not really 5G speed at all. I've gotten true 5G on this phone a couple times and it's amazingly fast. The 5G icon fades an drops too 4g when it does it kicks me off discos hotspot an network sometimes. I just don't have the will to deal with tier 3 tech anymore lol. I had prepaid for seven years with Verizon and it worked flawless many different phones over the years soon as I got postpaid went to hell

I'm in New Orleans and delt with all Network connection problems too. I'm on my 3 rd replacement and spent hours, days, and weeks ping-ponging through Verizon finest bull**** techs, Verizon sent me to OnePlus tech where the tech there referred me CDMA LESS and after a long work about found out that I was already on CDMA LESS. The only thing that helped other than bazilion factory resets and it's not the solution by any means is turn the automatic best Network set it to manual Verizon 4g. You still get the stupid 5g emblem but I've noticed an improvement as in connectivity. Not stable, I get interference and dropped calls all the time. Also i read something on how Verizon used cheaper antennas for their fake 5g push. Also could this be a conflict with Oxygen? I'm reading a lot of similar Network issues after updates.

Right on thanks, Not sure if manual mode actually sticks. Does it just switch back? But yes I too figured it'd help out. When I do let's say Run a diagnostic from Verizon's app one of the first things it says is this phone cannot auto connect to use lte/cdma for better signal. And that's wild it's connected and automatic mode. So it's obvious it's a hardware issue or software issue on their end. If they would allow you to control the phone we could fix it. Just got my first replacement today. Fixing the boot it up soon and see what the deal is software wise etc etc. The connectivity issue were both having is just 1 issue lol. I've got six or eight more easy. Mine seems like it's good data connection wise either with the fake 5g icon or without it. Bars will start fluctuating pretty rapidly (It's searching) I'll lose the 5G icon in turn lose hotspot lose date connection etc. Then it will come back with no 5G icon, connect, Be gr8 for about 10min or I reset prl & net setting. Someone tell me there 5g for most parts like here & there is basically just a glorified 4G LTE. There 5g coverage map clearly says or did there's no 5g here. I believe this to be true as I have connected to real vzw 5g in Tampa an you can tell big time!! This 5g even with there signal booster they sent me is not any if all better than 4g. Could kinda care less about the 5g it's the consistent intermittent network issues. Pls lmk what you find out either by p.m. or what have ya. I'll do the same. I'm gonna try this new vzw root I believe an switch too global or whatever I need too do weather it voids certain things or not lol. Sorry 4 the long read but wanted give ya what I knew. Here's a shot of there diagnostic mess. From vzw. An a shot of real 5g speed test before the updated deal that displays the 5g icon

T-Mobile Anyone Unable To Access Certain Websites

I have noticed this over the past several months and it is constant. Using multiple TMO Sims in multiple unlocked devices. Several websites will not respond when using cellular data. Those sites respond just fine when connected to WIFI on the same devices. Originally seemed to be a DNS issue but using T-Mobile DNS servers the sites seems to resolve correctly. Aside from not responding to web requests they also do not respond to ping either. My guess is that this has something to do with IPV6 but even when changing apn settings to strictly IPV4 the issue remains.
Do any other T-Mobile users have this issue? We have 1100 lines of service on several different unlocked devices all with the same issue. The easiest site to test this with is t-mobile themselves... T-Mobile.com will never respond when trying from cellular data. Also several MS Office online sites fail as well.

@stevecast2024,
Steve, I am on T-Mobile as well. Could you give me some specific sites you are having issues with ?
I would be happy to see if I am having similar issues on these sites.
Thanks my friend.

Sure. Thanks for the reply. Here are a few:
T-Mobile.com
Login.yahoo.com
wunderground.com
Sprint.com
The sites will simply time out. Work fine on wifi.
I also have noticed issues with some apps. For instance Zello, works most of the time but occasionally they shift login servers and we have to disable tls/ssl in the app in order for it to connect. Very odd. Unfortunately, that is a bit more difficult to troubleshoot.
Thanks

If you are on Android 10 and you have bootloader unlocked and rooted, then it might be Android 10 prohibiting you. I can't do anything on Firefox now.

OK @stevecast2024,
I have tried each of these 4 sites on:
1. A Windows 10 desktop using Chrome and connected using GB wired ethernet to a Cox cable modem.
and​2. A T-Mobile branded OnePlus 8T (unrooted, bootloader locked) using Chrome and connected solely thru a T-Mobile 5G connection.
Note: both systems were connected using both ipv4 and ipv6
My results were as follows:
T-Mobile.com: Worked as expected on both systems
Login.yahoo.com: Worked as expected on both systems, however, the phone showed a more simplified interface compared to the desktop
wunderground.com: Worked as expected on both systems
Sprint.com: On both systems, redirected to T-Mobile.com, but then displayed a popup saying:
"Sprint has joined T-Mobile!
We're so glad you're here. If you're a Sprint customer, tap 'Continue' to access your account and more."
In short, I did not see any connectivity issues at all on these sites. I will continue to test these sites from different locations and at different times to see if I can recreate any of the issues you are seeing.
FYI: I am in Las Vegas and I have been VERY pleasantly surprised with the 5G coverage and bandwidth here so far.
May I ask where you are located ?

My phone has Android 11 and does not have issues with any of these sites. I wonder if it might have something to do with the 5G network upgrades in your area. Maybe a glitch was introduced in your area when the network was upgraded

Unfortunately, @stevecast2024 indicates he is seeing this issue on nearly 1000 devices of varying brands and android versions. That certainly doesn't sound like a defective phone

Thanks for testing. I'm on the east coast. Just outside of Philadelphia Pa. None of these devices support 5g but I wouldn't be surprised if the 5g upgrades may have something to do with the issue.
I will say I am beyond happy with the coverage we get from T-Mobile here. We bought the CAT S42 phones due to durability and their support of TMO LTE band 71 600mhz. The 600 mhz coverage is phenomenal.

Yes, before I had a 5G phone, my 4G LTE here was frequently band 71 and was also fast.
I was thinking, you could try connecting one of your phones to a PC and adb shell to the device.
You should then be able to try some command line DNS and/or TCP connections, narrowing down what is happening.

So yesterday our Sonim XP8s received an upgrade to Android 10. Now not only can we not access the specified websites and many others, but we can no longer use the ZelloWork application when on mobile data. As soon as wifi is turned off Zello disconnects and will not reconnect until wifi is turned back on. Errors in the Zello Log show Failed to read public key.

Question GSM issues, sudden disconnection?

Hey guys,
So I've received my P7P a couple days ago. Ordered in Romania from the official Amazon Store. 5G, VoLTE, and VoWiFi don't work, as you all know.
But the biggest problem I have is that the network just completely disconnects if I leave the phone on the desk for a couple minutes. I have people messaging me and asking why they can't call me. When I look at the phone, there's no GSM signal of any kind. This is in a location where I have full 5G coverage otherwise.
I had to go into airplane mode 2 times before I was able to receive a call. The first time it connected to LTE for a couple seconds and then it completely dropped again.
Not to mention it takes forever to connect again after going in an area with weak signal.
I've updated to the Beta and the issue persists.
Great software, great camera, whatever, all useless when you can't fulfill your main purpose of being A PHONE.
Anyone else with issues like this? This is all I've found: https://piunikaweb.com/2022/10/20/pixel-7-7-pro-no-network-or-no-service-connectivity-issue/

Does the phone have the LTE bands it needs to even work where you live? If not, then I doubt there will be anything you can do but return it and look to another OEM.

oh LTE works well. 5G doesn't work.
It just gets disconnected from any kind of cellular network and gets no signal after a while.

Have you taken the day one OTA? That fixed the problem for most of us. I haven't seen any X or ! since the first day. Before that update I was having my connection drop every 10 minutes or so.
If you already have taken this update, you may have a defective model.

Try force stopping Carrier Services and Google Play Services and deleting the storage for both. That help me tremendously with connectivity issues with Pixel 6 Pro.
Might want to try Carrier Services beta as well.
Another thing to check is your APN settings. Make sure they're what your service provider recommends

I immediately updated before unlocking the bootloader and rooting, I don't have network outage or anything. 5G seems to be working as well, at least available in settings, I'm yet to test it in 5G area but where I live, there's no 5G actually so it would not bother me much anyways. I'm so far very happy with it

Question Significantly degraded internet performance (P7P)

I've been using my P7Pro for a while now, and every now and then the phone just seems to drop out of internet connection (non cellular related, was totally good). I get full signal and full speed on wifi and cellular on my other devices while my P7Pro is barely able to send a message.
Rebooting the device *sometimes* solves the issue and it will work fine for a very long while. But then it will do it again.
Had this happened during the cold and indoor so I'm confused af about this
System info & Plugins if anyone's curious
January update
Magisk Delta by (I can't quite remember on the top of my head, it's in this forum) That enabled 32bit support
Lsposed with Telegram module and Twifucker
USF by krad0n, works great
Kris Kernel 1.2.3 with Powerhint module
Everything else works great

Do you by any chance use any adblock DNS filtering? Something like AdGuard for instance?
I had some issues on by P7P and the old OnePlus phone and DNS filtering was the culprit. That's the only thing I could think.

I had AdAway running in the background (in root mode, which is static) and Never thought much about it
Will check to see if it helps.
Thanks for the tip

Any vpns?

DNs changes will definitely affect some websites, I have VPN on all the time and haven't experienced any issues ( i don't use the one offered for Google as it stopped working for some reason and either way it's not the best pot there. Also check adaptive connectivity options as that will make your connection wonky. I don't use root or any mods on my device so it's.fully stock.

All good, I usually have these connection issued with VPNs and DNS blocking. I just configure the system's private DNS for now and have no issues.
Good luck!

No, I mean... I have them (my own servers, ran Through Trojan Protocol) and they works fine. It could be related but tbh I didn't have issues when using them

There was something with adaway a few weeks ago or so where I had to temporarily disable it

I get drop outs from time to time. Figured it was Adguard. I just stick it in airplane mode for a few seconds, and then it comes back. Mostly happens when I go from wifi back to cellular

There is definitely something wrong with the latest January releases. Both the stock version and the beta releases (on my device) drop downloads repeatedly. Also my device keeps losing connection and switching from 5G to 4G to LTE in the same location. Maybe on the Pixel 8 Google will finally go back to Qualcomm antennas.

Not gonna happen.

I haven't had a single issue since switching to LTE only (5g is spotty in my area anyways). I think the radio gets stuck searching and switching between the 2 sometimes. I noticed it most when inside buildings and this has completely solved my issue. Even in rural areas, it has remained consistent. I would recommend just using LTE and see if that has any effect.
Edit-I know you stated it wasn't cellular related and I thought mine wasn't either, but this worked for me for whatever reason.

I happen to live in an area where 5G is good on Mint (T-Mobile). I always get a solid 5G UC.
But I find that 5G is NOT all that different than LTE in real world day-to-day use. In fact I doubt that anyone could see any difference at all unless they were using an app to actually measure any difference. SO if you live in a spotty area for 5G then by all means just turn it off (it's great that we can turn it off) and stick with LTE and be happy!

Agreed, and I also work out in rural areas often, where 5G is spotty, so I just keep mine set to 4g Preferred

I've had similar connection problems but it was location specific. I live in Phoenix, AZ where my signal and connection were great with no issues on TMobile. When I visited family in Austin, TX I would get constant problems. Often I would lose signal and never get it back and would either restart my phone or just in and out of airplane mode and everything temporarily works again.
