Hi all,
I appreciate this may be more of a network than a hardware problem but I thought I'd check anyway. This morning I lost data connectivity on my SGS. Phone shows strong signal but I can't access any web sites or sync with mail etc. Looks like the last sync was about 8am this morning. I contacted T-Mobile who suggested I manually reenter all the internet/MMS settings, which I dutifully did but still nothing. The phone works fine, I'vemade and received calls and sent and received sms. I can't figure out what this may be. It certainly doesn't appear to be a hardware problem but T-Mob couldn't initially see any problems eitehr. Does anyone have any experience of this sort of problem?
Many thanks.
Reboot your device.
I faced the same problem earlier. I deleted GPRS settings and recreated a new one. Then rebooted the phone. Everything worked fine.
Greetings. I am a new user to XDA but a longtime reader and geek who uses and is well familiar with multiple desktop and mobile OS's. I say this because the problem I am writing about is possibly the most confusing I have ever faced. In fact, if it wasn’t happening to me personally I would swear it was impossible, so please read on. I would be grateful for any – any – ideas. I will attempt to describe the problem and my troubleshooting steps as clearly and concisely as possible – but it’s a weird problem so needs some discussion.
PRECIS: Samsung Galaxy S II intermittently loses ability to connect to and sync with IMAP servers, BUT ONLY intermittently and ONLY on one particular mobile network. Much testing has been performed as detailed in this post.
HARDWARE / OS: Galaxy S II originally purchased on contract from Three UK, unlocked, and currently running Android 2.3.4, debranded to XXKG5 firmware and generic CSC XEU.
SIMs USED: Roshan (Afghanistan) pay-as-you-go and AT&T (USA) contract with unlimited international data.
SYNOPSIS: I have good data connectivity (slow EDGE, but generally reliable) from the local Afghan provider Roshan using my PAYG SIM. I am able to set up both of my IMAP accounts, have them log in, sync, send mail, etc, but after an indeterminate amount of time, routinely lose the ability to connect at all. However, all other data services and syncing continue to work fine (web browsing, Gmail, calendar, contacts etc) – only IMAP connectivity is broken. No errors appear, but mail just stops coming. Once this has occurred, the only thing that seems to correct the problem is time – it will eventually start working again, but is by no means reliable. Changing how often the accounts check for new mail has no effect. A change to Wi-Fi restores connectivity to the IMAP servers immediately, but then the problem returns over the Roshan mobile network. Yet, I can swap in my AT&T SIM and all works fine immediately, reliably, and never displays the problem. The IMAP connectivity issue exists only with my Roshan PAYG SIM, and only after some amount of time.
HARDWARE TROUBLESHOOTING: The phone and IMAP have worked fine on multiple networks in multiple countries. In the UK, on 3UK and Orange. In the UAE, on Etisalat and du – all with good HSDPA connections. In Afghanistan, the AT&T SIM connects usually to Etisalat but other networks as well, all with EDGE data where available. (Unfortunately for scientific testing, AT&T does not allow connection to Roshan.) And also in Afghanistan, my PAYG Roshan SIM works fine with everything EXCEPT the IMAP problem. Altogether, it seems the GS2 itself works as advertised.
MOBILE NETWORK (ROSHAN) TROUBLESHOOTING: The exact same PAYG Roshan SIM which causes the problem in the GS2 allows a reliably-syncing connection (and servers automatically detected, BTW) over the same mobile network to the same servers using my old iPhone 3G running iOS 4.2.1. Likewise, my boss has perfect service to these servers using this same network with his Roshan PAYG SIM in my old Nexus One on Android 2.3.4. And, my GS2 does fine on this network for all except IMAP.
ANDROID OS TROUBLESHOOTING: In an effort to troubleshoot a potential glitch in the OS, I have flashed multiple versions. The Roshan/IMAP problem exists on both the 3UK-branded H3GKF4 2.3.3 as well as generic XXKG5 2.3.4. And again, a Nexus One running 2.3.4 on the Roshan network does fine also – incidentally also in my office, so at least theoretically connected to the same cell path.
EMAIL CLIENT TROUBLESHOOTING: In an effort to isolate a fault with the Samsung email client, I purchased and installed Enhanced Email, with both 2.3.3 and 2.3.4 installed. Same results: fine on Wi-Fi, fine with AT&T, unreliable in both clients with Roshan PAYG SIM.
(LACK OF) CONCLUSION: Can it be possible that I have uncovered a ridiculously obscure bug? How can just one data service type (IMAP) be affected on just one network (Roshan) yet all other services are fine, and the IMAP problem does not exist with other SIM’s and/or networks? Is there anything something like a traceroute I could run to see what’s happening to my IMAP requests?
If you’re still reading, thanks for staying with me this far. I’m completely baffled, and frankly, more than a little frustrated that what is meant to be the best smartphone in the world can't reliably get my mail on the network I need it to, while a tired old iPhone and Nexus do so all day long. Any ideas?
Kind regards,
Adam
UPDATE: Did nothing, started working
All --
For the past two workdays, IMAP email has arrived in both the Samsung Email client (set to check every 5 minutes) and Enhanced Email (set to check every 10) on the Roshan mobile network. I have done absolutely nothing to cause this to happen.
Of course I am very pleased all is working as advertised, but the episode has still somewhat tarnished my previously stellar opinion of this phone and diminished my trust in it to a degree. Regardless, I'm glad. If the problem resurfaces, I will repost here.
I suspect the reader will agree that "it just started working" isn't a very satisfying fix, so if someone else experiences a similar issue with IMAP and/or knows more about how it works, I would really like to learn. Feel free to drop me a line on <<[myxdausername] at gmail dot com>>.
Kind regards,
Adam
Hi Guys,
I have searched around for any word on this problem but cannot find anything about it so I'm turning to the experts, LG's so called support certainly don't seem to be able to help me.
I got a new LG G2 on EE in the UK last week and have just arrived in Australia for a week of business, my Exchange account is all set up on the phone and working seamlessly in the UK however now I'm roaming it keeps reseting itself from 'push' to 'manual' and, when it has done so, the relevant box in e-mail settings is then grayed out and I cannot change it back again. I have to reboot the phone at which point it goes back to 'push' again, for a while anyway. My data while roaming, sync and data settings are all on.
Any thoughts?
Hi all
Since i flashed the firmware i9505XXUEMKE (android 4.3) on my S4 (i9505) i have an issue with synchronizing apps like whatsapp and facebook on WIFI. The issue is that it takes up to 30 / 60 minutes before the apps synch before I receive new incoming messages. Everything works fine on Mobile Network (LTE).
Do you guys have an suggestions / solutions to solve this issue?
Kind regards
Hi,
Since the update to Lollipop 5.0.1, my Note 4 cant sync any more with Microsoft exchange over wifi. Over 3g everything works fine. Over wifi the only problem is with exchange since the rest of the services and the Internet works fine. Before the update everything was ok. Already deleted and created the again wifi access points and also deleted and created again the Microsoft exchange account and this bug persists. . I'm also tried full erase of the phone, and still the big BUG in Lollipop continues to happen. Anyone else experience the same problem?

Same problem here, since Lollipop 5.0.1 update can't use my Hotmail / Office 365 work email with Exchange over wifi and works fine over 3G .
I hope the problem will be solved in future updates... :crying:

I had the same problem as well (my boss has a Samsung Note 5 and Lollipop did it to him as well).
The only solution I could find was to purchase 9 Folders as a replacement. It works like a charm and integrates into S-Planner (which means it works with my Gear 2 Watch) so all is well!
Solved!
Hi all,
I contacted Samsung customer service live chat to solve the problem and through the app "Smart Guardian" a technician has been connected to my phone to check the problem.
It was problem of the APN settings of my mobile operator (Movistar Spain). Erasing the "Proxy" field and saving the changes my email accounts works fine through wifi.
I hope it also work for you too!
