Mobile data + GPS issue - solution found. - ZTE Axon 7 Questions & Answers

On different ROMs, my experience has been that after a few weeks, my mobile data becomes unreliable (data connection lost, 'x' on the bar symbol in the status bar). Sometimes, mobile data could be restored by switching between 'Global' and 'CDMWMA/LTE...'. More often a reboot was necessary. Then, gradually, the number of reboots increased until I had to reboot multiple times/day. Concurrent with this, GPS lock time increased dramatically (maybe because of no data, but also when I have mobile data connection).
I have now finally found that creating a new APN solves this problem. I just go to \Settings\SIM Cards\Card 2\APN and basically copy the individual settings of the APN of my provider to a new APN and all the problems disappear.
I have an A2017G with 2 sim cards and an SD card.

I believe the Google Carrier Services app causes issues after an update. Nothing to prove that but it seems I have glitches after an update and go to check my settings then it seems to work better.

Where exactly in Settings do I need to go for this?
Also, update: on my 2nd day with RR (2017-12-18 version), I lost my mobile data connection and only a reboot brought it back. So not sure my APN solution works in this case. The APN solution above worked on AOSPExtended. Looks like I will need to continue to look for the real root cause of this.

Rogue Data Connection while BLANK apn is selected

Hi everyone. I have a problem that makes NO sense at all - but it's still a problem. Here goes:
As per recommendation of a number of people around here, and because I do not have a data plan, I have had two APNs for a while now: one was the real orange UK apn I use (let's call this "real") and the other, named "null" was empty (let's call this "fake"), so that I could switch between them and avoid paying most of the time. This worked perfectly up to...
The day I received an sms (perhaps mms? not sure) from 1550. As far as I know that's the number Orange UK spams its users from. There was the text "RockCorps" and a very small attachment (15kb I think). I accidentally pressed the "download" button but did cancel right after. I'm not sure if anything downloaded at all, but I didn't actually notice anything different, except...
My data connection was suddenly on. I could see the GPRS icon, and NetSentry also reported transmitted data. I checked the apn selection screen, which confirmed that my apn was still set to the fake one. But data was being transmitted!
So while I am using a fake, blank APN, gprs goes on and off as it pleases and transmits data.
I find this very alarming (and costly). I have tried to fix the issue by:
*selecting only 2G networks (to be safe)
*turning off always on mobile data
*turning off pretty much any phone setting that have to do w/ mobile data/GPRS.
*deleting ALL apns and re-creating them
*restoring apn list to blank factory setting and then reentering both apns.
NOTHING has worked. The phone still acts as if I have the real apn selected although the fake one is selected.
The ONLY method I've found so far for the phone to stop rogue GPRSing is to delete the real APN from the list. But whenever I add it again, without selecting it, the phone exhibits the same behaviour I describe above.
I'm clueless and a bit worried here. This is not making any sense, and the exact same settings I'm using now were working perfectly exactly up to the minute I opened the aforementioned message. Can anyone please help?
---further phone info----
HTC Magic, w/ cupcake, bought in Greece fully unlocked, with NO settings/added applications added by the carrier. NOT rooted.
Using it in the UK, on Orange mobile pay-as-you-go.
I had to enter mobile data settings myself: only entered GPRS apn (I'm not sure if that's a choice or up to the provider, but I've never seen any edge/3g icons up there).

MMS&Data Connection Problem..

Apologies if this has been posted before, I have tried to find topics similar, but have found no resolution thus far.
My X10's data was working perfectly, then about 2 weeks ago, market stopped working at "Starting Download" never completed, and I couldn't download Apps! This suddenly fixed itself one night randomly, and all my apps downloaded and installed, but instantly the market problem continued when I tried to use it again!
Now, the 3G/2G connection is totally non existent, there is NO icon at the top.. I have tried restarting the phone, turning it off and on, sim and battery out, even calling O2 to get correct APN settings (Server field is black, is this right?) and I got no "green light" beside "mms" at the APN type field..
The signal was fantastic before, and my family are still getting 3G connection on their phones, so I ahve no idea what the problem is.. I installed a few battery saving things which Iv since uninstalled.. but i have no clue what to do!
Any help would be much appreciated.. Thankyou!
suggest backing up your apps and then doing a factory data reset.. it's a pain in the proverbials but worked for me when this happened a couple of months ago.
How do I go about doing this mate? Any easy way?
Hi - Before you do this.. Can I just check something.. have you check in your network settings that it's not switched off... settings; wireless controls; mobile networks; MMS and data (needs to be on!).. and network mode - best to have it on GSM/ WCDMA Preferred to make sure... otherwise.... to answer your question above..
That will depend on whether you've already downloaded a file/ app manager such as ASTRO which will allow you to back up the apps.... if not you'll just have to make a note of which ones you want to reinstall and re load them after you've reset the phone.. the reset is done in the settings menu - sd card and phone storage - factory data reset... it will reset your phone back to how is was when you first got it though..

[Q] Frequently lose APN / mobile data

Hello,
It seems I frequently lose my APN and Mobile data. Every 30-40 mins if not used, it's gone.
I have to go to Settings>More Settings>Mobile Networks>Access Point Names>APN (not set)>and type in: vzwinternet... a few seconds later it pulls the data and works fine. The next time I need it, gone.
I'm running Hyperdrive ROM at the moment but have tested Jellybean, Baja and a few others with the same issue.
I have reformated, deleted and wiped all rom slots in safestrap.
My search of this forum and of google yields me a previous issue similar to this on an LG from 2011, and google reveals people looking for APN settings but no real solution.
Any suggestions are appreciated.

its not big problem. if you can't access the apn then just use the apn of you prepaid.(your phone must be rooted and restarted). but knew that this phone gets the anp automatically.

It's not prepaid. It's not a big problem, just annoying. After I set the APN to vzwinternet, I save it. It still does not hold the settings. I am rooted, obviously, had have re-booted, and tried with other roms as well and have the same result.

Urgent Help require: Note 3 “Smart Network Switch" not working anymore.

Hi there,
Recently I discovered this issue: the “Smart Network Switch" is not working anymore.
For me this is very important, as here wifi connection is not that great like the Mobile Data network here. Wifi internet sometime downs without any notification but Mobile data network is 100% uptime 24x7. But so far the " Smart Network Switch" helps me great as I’ve to stay online over skype always, if the wifi lost internet then it automatically switch to HSPDA which helps me to stay online always even if I’m unaware the wifi internet is down.
Earlier even if the wifi internet link is ok still sometime it was switching to HSPDA by saying internet is slow, I don’t mind that but recently I was noticing even if the wifi was down for long time it wasn’t switching to HSPDA.
In short the "Smart Network Switch" isn’t working at all at any condition. I doubt it could be due to any recent installed app. But I’m not sure which one could. I checked the all recent installed apps accessibility list and removed Airdriod and CM Security which had full network access. But still that didn’t help.
I’m sure this is due to a software bug not a hardware issue. For more input and clues:
# Since over last six month my phone lost the vibration, the vibration motor is not working, I tested with hardware test. I’m really not happy with this phone. Its not yet completed 1year and couldn’t find any nearest service center. So its still working without the vib feature.
# Recently I’ve upgraded the local WIFI setup with a primary dual band TP-Link router and another wifi router as bridge with same SSID and password, this is to get better wifi coverage. Due to this dual router the wifi coverage is at full bar everywhere and the phone has the same. But I think this is nothing to do with this.
Please advice. Thanks in advance.
Have you tried a factory reset?
Have you removed the certificates from those apps?
Have you removed them as device administrators?

Thanks for your reply. No I don’t want to factory reset for now, this would be my last option as I have to a lots of work to get everything back, apps and data, setup etc.
No I did not removed the certificates from those apps. Never did this before. When I uninstall I always clear all data of those apps and then uninstall. How do I find certificates of those apps? I know the certificate location but don’t know how to find those specifically.
I removed them as device administrators if its require, if a app in dev admin, it cannot be uninstall.
Please advice. Thanks
Sorry, credentials, not certificates. Bloody autocorrect....
Settings > security. Scroll all the way down. You can either clear all user-added credentials all at once by hitting clear credentials, or look it up and deselect it manually under trusted credentials.

Yes here credentials are CA certificates, after reading your 1st post I checked that but there was none user added, all are system and its a huge list. Also the clear option grayed out as nothing there to delete.
I wiped system cache partition from recovery, ran it under safe mode but nothing helps. So I doubt this will fix even after formatting to factory setting. It could be a hardware issue.
The issue has been fixed after formatting and factory resetting the phone.

Yes but this made my work increase a lot to get back all previous apps and their data. Kies app backup didnt backup app data, only the apps itself. I didnt know that. It took me a a day to get every setting back. Their could be another way to clear data somewhere which I couldnt find.

Any way it was very important for me, so that had to go for this. Thanks for the advice BTW.

Google Photos "Waiting for Wi-Fi"

So 100GB free for two years on Google, great, thanks!! They did similar with Dropbox back when I got my Jewel. Ideal purpose here is photos of my kids getting backed up, I don't create nearly that many spreadsheets to warrant that kind of storage.
Photos WILL NOT back up photos via wi-fi, the Assistant in the app just says "Waiting for Wi-Fi", well the wait is over, you've been connected to wi-fi almost constantly for a week now. As soon as you flip the switch to use mobile data, they back up fine, over mobile data. I'm unlimited, so that's not a huge issue, just seems like a power drain to me.
I've done all the toggling on and off, uninstalled app (updates to system app only, not rooted yet so still on stock), cleared data/cache, blah blah blah. Seems like the app isn't allowed to see the Wi-Fi state or something. I've Googled the issue and I don't seem to be the only one facing it. Only thing I haven't tried is removing my Google account and re-adding it, but someone else on another forum states to have tried it to no avail.
Has anyone here on this forum of geniuses seen this and figured it out?????
thanks!!!
I have had the exact same issue. I had to set it to allow it to use wireless network and then turn that back off. It's a crap work around I know, but at least they get backed up.

that's kind of where i'm at. mobile data is the only option. just don't know if it's an app thing or something with sense. haven't tried a factory reset yet, but i give myself probably another three or four days before i finally break down and unlock so i guess i'll find out then if that fixes it.
Mine still went over wifi. I just had to switch it to allow over wireless.

how could you tell?
Could be wrong but think he is saying he set to wireless network then back to Wi-Fi and then sync. I had same problem so just left mine on both Wi-Fi and wireless network. Would rather just Wi-Fi but don't want to lose photos

I thought that might be a possibility, but none of the above have worked for me. Mobile data only
I have the same problem. There were a few times early on that I got it to work on Wi-Fi by toggling and clearing stuff in various combinations, but never consistently, so I just ended up saying screw it and using mobile data.
I remember that I had the same issue on a stock Android ROM on my M8 at one point though, so I don't think it's a sense issue.

Same issue here. I ended up just letting it go over mobile data (especially since I have unlimited data with Sprint)
Was on vacation so I couldn't reply.
I have zero cell coverage at home so data cannot cross the cell network. I had issues with it not uploading over wifi. I set it to use cellular data and photos started backing up. Obviously it's only over WiFi because I don't have cell coverage at home. Turn off the cellular data backup setting and it stops uploading on WiFi again.
same trouble with a HTC 10 Port on my HTC m9
I had the exact same issue, and found the fix on reddit.
"Go to Settings, go to Data Usage, then open the menu and go to Network Restrictions. Tap the WiFi you're connected to so it is a metered network, and turn it back off. Should correct everything."
For whatever reason, toggling that setting makes Photos start backing up over WiFi again.

This issue goes beyond just Google Photos. I have noticed that it is global so anything that is set to download over WiFi only won't ever download. This includes automatic updates in the Play Store and Spotify downloads. There has to be a fix coming for this soon from HTC. I wonder if they are even aware of this bug...
just want to let you know guys this is no HTC related, I have Xiaomi Mi4c with CM13.1 facing exactly same problem in Flickr and Google Photos app, only solution is mentioned in this thread enable and disable your wifi network as metered.
EDIT: I am using AFWall+ and both Flickr and Google Photos had same issue and were restricted by firewall only to access Wifi, I am curious if it's gonna help if I will allow them to use mobile data and restrict only within the app.
I can confirm that here, definitely something up with the app. Did the meter toggle fix, disabled mobile data, snapped a photo, watched it back up over wifi. Then for fun I went into backup settings and turned off backup over cellular data and snapped another photo, waiting for wifi.
Hay guys i was having the same issue of not being able to upload my photos on google photos app, but i don't know when it started up and what caused it to do so, but i have digged up a solution from googlephotos help page, a guy named Gaieus solved this problem and shared his steps there. I have just copy pasted them here ,
I had the same issue. I finally found what to do and it seems to work for me now (hopefully for others, too):
Go to your settings > data usage
Tap on the three dot-menu icon at the top right
Select mobile hotspots
Uncheck your own (or any constant, reliable connection you often use) so that it is not marked with green as a mobile hotspot
It seems that the phone is not using mobile hotspots to do the background uploading (probably because they are often unreliable and you may not stay in the range for long enough - and as has been said, the pho app cannot do resuming of uploads already started when you get to a wifi range again)
So press thanks button if i helped you guys. Thanks for visiting XDA
I had the same issue for the long time and I just now managed to fix it.
Go to the Settings and fully FORGET your WiFi connection. Reconnect by entering again your password.
That did it for me. After half a year of inactivity, Playstore immediately started updating my apps and Photos started backing up over 430 images that were in the que.
Switching to mobile data also fixed "waiting for WiFi" holdup inside Photos app, but since I am on 500MB/month data plan, I never relied on that.
Did you guys have an SD card formatted as internal? I think the issue stems from that. I had the same issue a while back with more than one app like google photos, google play music (for podcast downloads), etc... basically anything that waited for Wifi to do anything.
I backed up and redid everything without formatting the card as internal and haven't had those issues since.
I've heard formatting as internal can cause other odd problems too.

Once I uninstalled all the Google Photo updates, it started working for me. The only Settings option I had available in the latest version was "About". After removing the updates, all the Settings items returned and so did the ability to sync.
