Debugging phone connectivity

Hi guys,
I'm still working on figuring out the connectivity issues of my O2X. My problem has been that my data connectivity intermittently drops out, and fails to establish one and move out of WiFi range.
I have completely reset my phone to stock with the latest updates available in Norway. This is baseband 622, and version number 10c. The problem I am consistently having is that whenever I have stayed on one connection type (WiFi or 3G/edge) for any length of time and then switch, the phone fails to establish a connection through the other service. This means that whenever I have been home connected to my WiFi for awhile and move out, mobile data is not established. Similarly, when I get home, it does not automatically connect to my home WiFi network. In both cases the solution is to turn on and off WiFi mobile data (sometimes several times) to re-establish the connection.
If I quickly moved in and out a range of my WiFi, the switches between the two connections without any problems.
This is with everything stock. Is there any point in trying the other basebands? I have tried a few of them already, but without consistently good results.
The alternative solution is to send it in for repair, but they will only tested, figure out that they cannot locate the problem because they do not have the funds stay with the same connection long enough, flash the phone with the latest firmware, and send it back. After repeat this three times, I'm entitled to a refund or a new device, but it means that I will basically be without my phone for around six weeks.
Any and all solutions are greatly appreciated.
Edit: I guess a possible solution is just to use Tasker or something similar to reset mymobile data connection when I leave WiFi, and regularly reset WiFi when on mobile data.

I believe I have the same problem.
The 3G data connection would drop about every 10 minutes.
I got the phone a week ago and it too came with 10c firmware and 0622 baseband.
I believe that this is a hardware problem because I have flashed other firmware + baseband combos and yet this same problem still occurs.
I have sent the phone back for repairs yesterday. I hope that they can fix this problem.

Again, its probably baseband related....
Same for me here

[Q] While in Europe: Moto X won't reconnect to cell data, post-WiFi use

Hey guys/gals -
I got my Moto-X a few weeks ago, and have been using it without issue on AT&T. Unfortunately, I'm just wrapping up my first trip through Europe with this phone (left my iPhone 5 at home), and I've noticed a very odd thing over the last week.
For some reason, my phone will not re-establish a cellular data connection once it has connected to WiFi (and subsequently disconnected from WiFi). I have noticed this - consistently - in both Germany and Italy. In all cases, once WiFi is no longer connected, I can see that the cellular data network is available (the 4G or E logo shows up, grayed out, next to the cell bars) but it will not reestablish. The only way to obtain a cellular data connection is to restart the phone.
I've tried going into airplane mode; I've tried cycling cellular data. Nothing I can think to try causes the cellular network icon ("4G" or "E") to cycle from gray to white...I simply cannot get back online without a full restart. But once I've restarted it works fine - so long as I don't jump on WiFi.
The phone isn't unlocked; it's an AT&T device, with no APN tweaks.
Anyone have any idea what could cause this behavior? Unfortunately, it's going to be another four or five weeks before I'm back here to test any ideas...but I figured I'd reach out while the issue is fresh.
Cheers.

Just to chime in, I've also seen this issue on mine, but it only happens with certain WiFi access points. After using the Cisco ones at work the problem occurs, but my Asus N66U doesn't seem to upset it.

[Q] Razr I - Failing to swap to Mobile Data after Wireless Connection out of Range

Hi.
I've recently started having lots of difficulty when moving out of range of my home's wireless signal in the phone picking up and connecting to the Mobile Data network.
Specifically:
1) Run phone for ages at home using wireless
2) Walk out of house, out of range. Wireless connection goes unconneced
3) Wait for Mobile Network to connect, have at least 3 bars of signal - fails, no E/G/H Sign, Network indicator stays white ( So far waited up to 3 hours)
4) Reboot Phone, instant Mobile Network Connection @ H
Things I have tried:
1) Turning Wireless off before leaving range of wi-fi, sometimes this works ( circa 1 in 20)
2) Turning Phone to Airplane Mode & Back - sometimes this works ( circa 1 in 15 ).
Turning Airplane mode on can take about 4 minutes, as though something is waiting for a closure timeout. Normally, this takes about 5 seconds.
3) Phone calls are intermittant during this time - sometimes I can make them, sometimes i can't.
4) While in range, turn phone off/on again so a "clean" boot, then walk out of range. No affect on ability to reconnect.
Check Phone Status under About Phone, the Mobile Network States reports "Not Connected"
It's really annoying, as I want to use the phone to during breakfast to check the latest traffic information and map updates from Google Maps before I leave home, then get in the car and go, not reboot the phone.
Has anyone else suffered a similar problem?
Phone Specifics:
Motorola Razr I XT890
Android 4.1.2 Stock
T-Mobile
Is there some investigative
Thanks!

I've had exactly the same issue on/off for weeks.
Not found a reason/fix for it yet, although I've been loath to do a full wipe with how busy I am atm.

Hmm.
At least we know we are not in the same boat, and a recent forum query on Engagdet highlighted others.
I've tried to capture a bug report to give me some logs to look at, but that's not working at the moment either !
Thinking it might be an "Always On" app related problem such as sykpe or amazon mp3 :S

Moto G (Dual Sim) Internet Connectivity Issues

Hi, I'm new here so forgive me if I do something wrong^^
First of all, I have a Moto G 2014, Dual Sim which is running on 5.1.1, to be more specific, this ROM. I was using this ROM for about 4 months already so that shouldn't be the issue. My problem is that after my phone connects to the internet, usually using H+. The connection to the internet is working perfectly fine, but after a while of not using the phone it loses the connection. It still tells me that it got a strong H+ connection, but nothing (browser, apps, anything) is able to connect to the internet. Enabling & disabling airplane mode usually fixes the problem. From time to time it also happens, usually when I lost some sort of wifi connection (regardless if I disabled wifi or I got out of range) it happens that it shows full connectivity but with an exclamation mark. This only goes away if I reboot or enable & disable airplane mode again.
Is this issue known/is there any solution to

I have been experiencing the exact same thing as of lately. I thought it was a byproduct of downgrading from (Stock) Marshmallow to (Stock) Lollipop (yes! it's happening even on stock ROM) where at times the WiFi losses connectivity when the phone had been sleeping for awhile...even though I have the "Keep WiFi on during sleep" option on under WiFi's advanced settings. I had no idea that it also happens with data connections ! ...as I don't use it (too expensive for me), now I'm uncertain what could be the cause. I can see how this would be an inconvenience if you use a lot of social media apps as I sometimes do not get my WhatsApp messages when this happens and sometimes I don't even receive my Hangouts messages until I open the app manually.
It's strange, at times when my phone sleeps for awhile and it losses connectivity and I wake it, it will reconnect just fine and other times it just goes into this state where it reconnects with full signal strength but with an exclamation mark next to the WiFi icon in the notification bar. When this happens, no matter what I try it stays in this state, I tried turning off WiFi and turning it back on, also forgetting the network and entering the info and reconnecting to it but none of that works. I didn't know that turning on and off airplane mode can help....I'll have to try that one, rebooting the phone was the only solution I found which is just inconvenient and somewhat annoying.
I too, am interested in a proper solution. I don't know why the phone ignores the "Keep WiFi on during sleep" option or why at times it connects but have not internet access! It should be noted that it's not a problem with the network, It's not due to an incorrect password or anything like that as I am the one that administers those things and when it happens other WiFi devices such as my Tablet PC, Laptop etc can connect and access the internet just fine and it only happens sometimes on the phone (Moto G 2014). This doesn't seem to happen in Marshmallow...but I hate Marshmallow and I can't remember having this issue on Lollipop post Marshmallow update (how I wish I had never tried out Marshmallow!!!), which is why I thought it was related to downgrading, .......did you downgrade ?

Question Wifi <-> Mobile switching?

I have this strange issue that has been with me almost since the beginning. I haven't been able to trace when it happens, but it now seems almost 100% of the time.
I only have WiFi in the house (wifi6, if it matters). If I go out, I only have 4G (I left only 4G and disabled 5G). I have no data until I put the phone into airplane mode and back, or I disable and re-enable mobile data.
Same thing when I go back in the house: no data until I disable and re-enable WiFi.
I've disabled the option for 'always-on mobile data' or similar, it's quite a battery drain if there's no cell signal.
Seems like a very strange bug, I don't have this with any of my other phones.

So you have both WiFi and 4G enabled and they don't switch seamlessly?

Exactly. I always have to restart each one of them, usually by toggling airplane mode. Was wondering if anyone else ran into this issue.

Ok this really is strange. There are 2(!) different toggles to enable data switching between WiFi and 4G, but for me it works flawlessly without them! As soon as I get out of my home WiFi range, 4G kicks in, and when I get in range again, the phone connects to my WiFi...

Hi, i have this problem too but it's not always.
I have a wifi 6 router too.

I also have problems switching from wifi to 4g. Need to toggle airplane mode on/off. 5g deactivated. No wifi 6 here.
I always assumed my vpn is causing problems during the switch to 4g. But hearing others have the same problem i would assume its zenfone problem.

I never had any issues in this area with my ZF8. With the option to have cellular always on I could walk out of my WiFi zone during a video call and no drop or short pause would appear.
With this off the network need a few second to work, and some apps need to be refreshed/restarted to gain connection. Never needed to toggle connection for this to work.
Maybe a reset would be enough or check for updates.

Ah, exactly! It does not necesarily need a network restart, but some apps just lose connection for a while, which can be from a few seconds to >1h. Which is even more weird as the icons are showing full connectivity. I would go out of the house, do stuff, come back later and I would only get the notifications when I'm back inside the house.
Rarely I had the connection drop completely (no signal) when switching, but I haven't noticed this happening since the last update.
