Hello
I've just bought a new galaxy ace 2 and I am experiencing some problems.
When I'm using only gsm network type (i think, now I'm testing HDSPA), typically, when I'm logged on icq, mobile sometimes loosses signal and displays there is no service. After few seconds is everything OK and network is back at full singal. This can be seen also in battery usage view, when I'm having always yellow line with thin red places.
I'm now using it with mixed mode on HDSPA and there are no problems with network.
The phone is under warranty, so there is no problem, but I dont have much time and first I would try other solution. I tried to flash it with odin to same fw, but no change. I tried to google it but I didnt find any solution. Could you give me advice?
Thanks for answers

Well the "train" issue is due to the train being like a faraday cage, blocking the various microwave signals, the reason you get a signal on a train is because they have amplifiers to retransmit the signal into the train and vice versa.
...what network?
I have problem with mobile data. Apn: ERONET START (gprs.eronet.ba) i can acess with other phone on my sim card. Problem is in my phone but i dont know how to solve it. I can send messages and call but no any sign of data

Hi, is anyone else having poor wifi connectivity on your M8?
My wifi signal will drop completely after a period of time. Conducted speed test and speed turned out to be much lower as compared to my Nexus 5 on the same wifi network, and somehow websites/apps take ages to load via Wifi.
Am on 1.54.707.7 (International) by the way.
Found a video that perfectly describes my problem. :silly:
Yes I'm having the same issue. tried turning off the power saving mode. what kind of works sometimes is if I turn off my mobile data off. I also heard that you Wi-Fi password needs to be 9 characters or else, seems like too much of a hassle. I haven't tried changing the password.

Finally someone who is in the same plight as I am! Haha yes I've tried that too, apparently the signal that the M8 is capable of receiving is weaker than other phones, have a friend who tried on a G2, an M8 and an Oppo Find 7a. The 7a had full bars for WiFi, 1 bar for G2 and the M8 couldn't even connect. :crying:
And about that 9 characters for password myth, yeah have heard about it too! Just counting that out as I don't see any impact it has on the WiFi connectivity though.
possible fix

Hi guys, go to advanced settings in Wifi and uncheck "wifi optimization" give it a try might help
The latest small update gets the WiFi working perfectly

noticed the same thing but i dont lose connectivity the thing is wireless is really good but the signal bars play alot and jumps but if i go a bit far from the router eg in the kitchen where most my phones couldnt get wireless connection i still get it with the m8
Have flashed back to sense to try something so tested once I saw this thread.
Am on 1.54.401.9 and still get the speeds below in my sig with everything set to default and no 'other' kernels installed etc
Ranges from 70mb to 108. (International / UK )
What seems to be working for me so far is I went into my advance Wi-Fi settings and change the frequency from auto to 2.4GHz only instead of auto. I haven't had any issues so far let me know if that helps

I've left mine on auto but connect to 5ghz. (both 2.4 and 5ghz available from router) and again get top speeds.
I don't have any problem at wifi connectivity.

Hi, that worked perfectly for my M8 and my wife's M7. We had big trouble on 2.4 Ghz Networks. After long and disappointing tests for trouble shooting I found this post. And it works. Thanks alot.
am too facing the same problem, wifi keeps dropping consistently.. this happens on each and every sense rom... even on the stock rom.
did a factory reset, but no luck.. also tried turning off and on the wifi optimization in settings-wifi-advanced & changed the wifi frequency band to auto, 5 ghz & 2.4 ghz, but no luck. like it means dropping 12-15 times in 10 minutes. the power saver is also off. wifi in aosp and gpe roms works fine. any suggestions? (firmware is up to date)
Was it due to full metal body? Wifi is worse than my old Butterfly 1
So, i'm in the UK with my nice shiny OP3 (on Three UK) - I am rooted with twrp, but same applies on stock.
The radio in this phone seems to prefer H+/3G to 4G, even though where i live, i have full bars on both. My nexus 5 always prefered 4G, and the OP3 is set to prefer 4G but 90% of the time drops to 3G/H+
Another interesting thing, if i use the testing menu to force LTE only, even if it's on 4G already, completely stops any signal getting through for a number of minutes until it decides to connect sometime later. I have full LTE signal in my room too.
Is this a radio problem that could be solved in the future with a software update? not seen anyone else with this issue!
FYI, when it is on 4G, it's super fast and stays connected until a reboot, where the whole process starts again

Check your APN.

APN Is exactly the same as my nexus 5, and i even added a new one. Same deal.
I'm an IT Professional, just not a developer. i've done everything i can think of. 4G does work, but only when it wants to. My phone is also registered with my carrier correctly.
Bump on this anyone?
I am having a similar problem I guess. I have the dual sims installed and one sim randomly shows no range. Further, the network preference is not the way it is supposed to be - Chose it as 4G and if 4G is not detected it falls back to 2G.

Same as you. Anyone know how to fix the network priority to lock onto LTE first and then drop to 3G for calls?

I did notice when I do have LTE it's fine but it won't re lock onto LTE after a call on Three where it has to drop to H
I'm having a problem where the phone catches 4G+ "carrier aggregation" and it'll jump from to 4g+ to 4g and back to 4g+ really fast like almost flashing . And speed test are showing low numbers. T-Mobile USA.

Same here. Sometimes it just locked to 3g/h+ in a strong LTE area for no reason. I'm on stock oos with one sim and 1 apn. Sometimes I need to reboot the phone to get LTE back.
Sent from my Pixel C using XDA-Developers mobile app
I first put my sim into slot 1 when I first got the device, I was having the exact same issue. I found that the data priority sim, or if you only have one sim needs to be in sim slot 2.

Yes exactly. And even then it doesn't show up straight away despite 3/4 and usually full signal. Sometimes just putting it into standby mode and leaving it 20mins can sort it... Until I get another call lol. Wondering if it's just a software or firmware issue that could be patched. Lte is fine it's just never preferred despite the options being set

APN is not the universal response. Here he faces a problem of inaccurate network type choice, APN is only to have acces to internet through the provider's proxies. It's a radio problem clearly, the baseband is probably to be corrected by OnePlus.
It's really a strange thing to see those network type issues, MMS issues are still present after all those years.

This is what I thought. It's probably an easy fix for oneplus or rom developers. Custom radios are nothing new. Let's hope so anyway!
This is happening to me as well. I'm on three in a strong 4G area but it always prefers 3G it's so annoying hope it gets fixed soon.

same problem here.
i tested op3 with 3 different carriers
on two of them - lte no problem, instant connect...
on third sim - slow connection, frequent out of range. almost no lte.
tested third sim on iphone - instant lte connect, no problem.
seems like a incompatibility with an selected cellular operators.

Could be but I'm doubting it. OP3 Has full support at least for my carrier on both bands they use (3 & 20).. Never know, the devs here will figure it out if oneplus don't

Same issue here, have never got it to say 'LTE' for me since I got the phone, best it does is 4G whilst my Galaxy S5 would happily pickup LTE. Just wondering what UK users have there preferred network type set to? Mine is on GSM/WCDMA/LTE I assume that is right as that is what it went to itself and have tried LTE or LTE/WCDMA too.

Sorry, i mean my OP3 shows LTE in statusbar but it runs with 2G speed
I have a problem with LG G3 858HK (dual sim).
Sometimes (once/twice a day) phone loses all signal, tries to connect, connects and loses signal again, again connects, loses and so on, and so on. It’s not only data, it loses mobile signal as well. And it happens in all kinds of areas, even where signal is full 4G. Usually nothing helps, except switching the phone off/on again or pulling the battery. Sometimes when switching it off while having this issue, it wouldn’t switch on again pressing power button. Again, opening it up and pulling the battery helps. Sometimes only connecting wifi/ disconnecting wifi helps.
Phone is running rooted android 6.0 (tried few ROMS, rooted/non-rooted - same thing). I tried everything to solve it: factory reset, changing sims, running with one sim, running with 2 sims (its dual sim phone), un-rooting, rooting again, multiple ROM's, tried all kinds of settings - nothing helps. The issue is probably with the phone. Sadly, warranty is expired.
Video of the issue: https://www.youtube.com/watch?v=qq7_jm0-Hp8
The signal in the area where video was captured is really good, full 4G normally.
Anyone got any idea what could be wrong with it?
Any help would be appreciated. Thanks.
Anybody?

Try it only in GSM network thru network settings and see if its resolved or not?

It wouldnt be worth using my smart phone for GSM mode only. Then it would be better just to buy some old Nokia 3310 But I'll try.
Hello everyone,
I bought 2 months ago a Mi Mix2 and I’m very happy with it
but since 2 days ago my 2 sim cards goes loop on 4G/lte option, either switches on and off without any connection (mobile data and WIFI).
Now the phone works good only in 3G data
I’m an expert user and I have tried many possibilities but without solution.
Installing other roms such as Global and China, stable and developer, formatting data several times, change SIM cards but nothing.
I also have read several forums without any good news.
someone has any good idea?
thx!

I've found that VoLTE conflicts (IMS maybe?) between SIM cards can cause this...have you tried ensuring that VoLTE is deactivated both in the settings menu and hidden testing menu?

Thanks, but Volte is disabled. I tried to enabe it but still Sim cards works only in 3G. I'm thinkink that Lte modem is broken...
Hi Stefano, I got the same problem. Did you solve it yes??

I have the same problem with xiaomi 5, but I found that whem my wifi conection is on causes problems with sim cards.
you can try this; switch off wifi. then restart your phone and you now should not have problems with sim cards signal, but when you turn again wifi the problems appear again, conflit with wifi,
I usually disable and enable the SIM Slot that have the looping issue. Not the mobile data, but the SIM SLOT.
Don't bother, it's a Mi Mix2 issue.
Phone has problems to switch between "receiving and making" calls and switching back to 4G/LTE.
And very often i can't make calls, cause the opponent can't hear me.
I do disable mobile data usage and/or enable airplane mode for half a minute.
It really is enerving. Thats a major issue.
Never will buy xiaomi again.?

I can confirm this issue... This is becoming somewhat of a deal breaker to me.
If anyone finds a working fix for it, do tell.

Same issue here.
Data constantly dropping. I'm not in a great signal area, but working fine on my Galaxy S8 for the past year.
To bring data back, I have to refresh it by enabling flight mode on/off. Constantly doing this.
Anyone know of a fix? I see someone above has flashed new roms, but no luck?
Do I just send back?
The issue seems very odd as I haven't encountered it even once today.
I'm getting curious just what might be causing it.
The only fix I found to work was by going to my cell provider. They provisioned my new Mi MIX 2 into their system (3rd phone - same sim card).
