I've had the US version for a few days now and figured I would share my experience thus far. This is not a definitive list. I ordered through sonystyle.com and am operating on T-mobile in the US.
The good:
1. Phone build is spectacular.
2. Screen resolution is the best I've ever seen.
3. Wifi picks up and logs on quicker than any phone I've had.
4. Touch-flo cabs can be added very easily. Can mix and match the two GUI's.
The bad:
1. Internet and regular calling access is sporadic. I need to perform a soft reset every few hours or nothing works.
2. A fully charged battery will be used up by evening if push email is auto and have moderate phone use.
3. The phone doesn't seem to be able to switch towers in the middle of a phone call. The calls are dropped and you have to call the person back.
Overall, the phone is really incredible and it's being hampered by OS build or something. If the phone didn't have the potential that it does, I would send it back. I figure I'll be patient and wait for the dev team to patch or cook something. I've used the HTC Touch Pro (Fuze) and the Xperia is definitely more sexy and has a better build and keyboard (personal opinion). It will be interesting to see if any others have the same issues and if it's associated with T-mobile US only.
cooool you have the X1a? Do you mind dumping your ROMs please?

none present on my X1i. For the battery, just wait, is still new... use it for 5/6 cycles and should be better. Also no issue for internet/calling and don't understand what you mean about towers...

1°) The BT and wifi are bugged. The BT disconnects sometimes (already told in other threads) and the wifi passwords are sometimes just lost.
But on 3G/GPRS/UMTS no problem and no need to perform soft reset.
2°) ouah, perhaps you have a problem there... I have (in France) a software that retrieves the mails (every 15 minutes) with a specific data connection.
This with some Wifi on, UMTS on and some calls, my X1i makes a lot more than a single day.
Did you install something that is draining the battery?
3°) weird, I live in a place where 3G signal is low, and I definitly swap from "2G" to "3G" without a hitch, even while a phone call.

I have not had any problem with #1 and #2, and I'm also on pushmail mode. By the evening, I would still have 50-60% depending on the activities I carry out with my Xperia during the day time (obviously lesser if I do alot of video playback, etc)
for #3, I doubt any phone would be able to switch tower w/o dropping the call. It's the case for any GSM phone, and I could prove that since I got a UMTS access point (equivalent of the tower except that this is a "personal" one ) at home, and once I walked out of the coverage zone, the call will drop regardless of which phone I hold.
By towers, I think he means cell towers, i.e when he is in the range of one tower, lets say while driving, then leaves that tower's range and goes oto another tower, it doesnt switch, it just drops the call.

Yep, I know where the points are on my drive when the range of one tower ends and the other begins. My previous phones could all make the transition without issue. My Xperia definitely can not. 25 minute drive = 3 towers and 2 dropped calls.
Had to soft reset twice this morning before I could get a call to go through. The phone says connecting and then connected but nothing comes through. Real pain in the butt.
Perhaps I have a defective model? Anyone else using X1a on T-mobile in US. I would like to know if it's a ROM issue that can be fixed or somehow the phone isn't compatible with T-mo US....

I wonder if the ril file jack posted would help?
What is that file and where can I find it? Thanks for the suggestion, I'll give it a shot.

yes I know he's refering to the cell towers.
I do have a home version of cell tower at home too. It doesn't switch and it happens for all the phones.

Sorry but you are talking crap. The whole point of the GSM standard is to get phones to carry on talking as you move location. I suggest you read about Handover (or Handoff). The Wiki page isn't the best I've seen, but it does try to explain it.

ok I stand corrected. my apologises.
I just noticed that my phone (and my wife's phone) cuts off once I move out of my home umts access point, so I assume its the same for all the cell towers. (on hindset, mine being be a scaled down cell tower so I shouldn't be using that to prove commercial one )
That said, in reading further, do you know if soft or hard handoff is generally implemented in CDMA network? I suspect it's the latter, and that probably explains why you have dropped call due to inability to switch to the new channel fast enough?

I doubt your home-hosted access point would be allowed to perform a handover with public cell tower, that's why it cuts off. It's like trying to move from one WLAN SSID to another. If you read more about handover, you'll notice that it includes a lot of security measure also. If handovering and handovered base stations are under different controller(RNC), all encryption information has to be passed from old controller to the new one, etc...
Yes, The point of GSM is that it 'hands off' the call as you pass by different cells automatically, so no dropped calls.
In fact, this is ONE reason they do not want people to use mobile phones on aeroplanes, is that since you would be on top of many towers/cells at one time, then they would be constantly changing/swapping among cells, and if there were a lot of people doing that, the chatter between the cells would be very great and overload them. Thats why they want to set up a cell on the plane itself, so that all the mobile phones talk to that cell only (as the strongest signal).
It has nothing to do with interference to the plane systems. If that was the case, it would be so easy for a terrorist to crash a plane, just bring on a radio transmitter and everyone dies.
Yes, it's the handoff that can't happen.
Othertimes, when I'm sitting in one place, I'll have 3 bars and the signal will suddenly disappear. The phone will take 15 seconds to reaquire and then it will be fine. Usually seems to happen when someone tries to call me. It's almost like the phone hasn't maintained a connection. Very annoying.
Hi all!
I'm an Android user. I use it heavily for web-based uses - browsing, streaming music and various network-enabled apps. And I'm a little disappointed. The problem appears to be a network issue, but many, if not most, of the time, I can't get a reliable data connection on my phone. GSM is totally fine - never had a dropped call or lack of reception. Just data. Even when I am in a area of strong coverage (full bars; 3G/HSPDA icon showing) I frequently am unable to do simple web access - can't open Google, or an app is unable to do light data connection (e.g. Facebook app grabbing a profile). Sometimes it works fine and when it does, it works bloody fast. But it's that unreliability that is frustrating.
Now, I'd go to my network and ***** about it but they - quite understandably - would be unable to do much about it without a more technical description of the problem. They'd just find some way to blame it on something else, as they do. What I'm looking to do is characterise the problem by gathering some stats on connection reliability. If such data could be collected, I would be able to back up a case that there's something foobarred with the network (or persuade myself that there isn't).
Question is: does such an app exist? I'm not looking for one of the many speedcheck apps; I'm looking for something I can run for a couple of days during which time it tries to make many mobile data connections. It would record success/fail, reported network strength/type, perhaps latency, connection speed and location as well. It would do so once every, say, 5 minutes, to build up a profile of how the reliably I can get my connections.
Anyone know of such an app? If not, I might write one; do you thing such data would be useful?
Sheepish bump...
We have many different devices here... Galaxy S2, Note 8, S3, Note II , S4 etc... Over the past few weeks we have had our Galaxy S4's start to run jittery, frequently begin displaying a message, "Can't play video" when attempting to play video loops in VideoView and random crashes/device reboots throughout the day. The strange thing was that we had many different S4's that mostly appeared to reboot at the exact same time. It also seemed like at about 4pm every day all of the issues would go away and return the next morning. It really had us banging our heads off a wall since this was effecting so many devices, however only S4's.
Eventually we found out what seems to be going on, although we are still unsure of why it is happening or why the other devices aren't seeing the same symptoms. We are convinced that this is two issue acting together... One with our network and the other with the S4 device itself.
We downloaded the app SystemPanelLite which shows us inbound and outbound network traffic as well as cpu usage. We ran numerous tests on many different networks and what we found was when we were our main company network the inbound traffic on EVERY device would constantly spike from 2.2mb/s - 3.2 mb/s which would cause the cpu to jump to high levels. We put a VideoView on a loop on one device, and on another device we would watch the inbound traffic on the network. Whenever the traffic would spike the video would start getting very jittery and even sometimes throw an OnError event with a what parameter of -1(Error unknown). Eventually if the traffic spiked high enough the device would simply crash and reboot. Occasionally we'd see the inbound traffic fall to 12kb/s and all devices would start functioning perfectly. We have a few developer S4's and we even have a few employees with consumer S4's who reported the issue of their devices rebooting when on the company network.
So we were seeing this traffic on ALL of our devices yet it would only cause the S4's to behave this way.
So I have a few questions:
A) What the heck on our network could be broadcasting in such a way that all android devices would be receiving so much data.
B) How could network data literally crash an entire android system? The system should be protected from such things. (this leads me to believe there is currently an undiscovered bug in a recent software update for the S4, since even my S2 seems to gracefully handle these network spiked without a hitch.)
I'd love to try and set up a test bed to duplicate this issue on a network but I literally have no idea what could possibly be broadcasting in such a way that would cause all android devices to accept such a huge amount of inbound traffic. Any insight into what could be going on here would be very much appreciated!
Thanks for your time!

So we've actually found that there is a device on our network that is blasting crazy amounts of "Neighbour Advertisement" packets. We've tracked it to an iOS device but are unsure who's it is. Anyway, network traffic should not be able to completely crash devices into a reboot state, not too mention the amount of battery is being used simply by having the device on the network. This seems like a pretty big security flaw to me.

I would start by changing your WiFi keys, that should prevent the traffic. Then - before granting access to WiFi via the new key - All devices should be checked for Malware and anti Malware installed.
This traffic is a warning - what if it was a virus that the iOS device was transmitting?

We have actually found out that it was instances of Hyper-V reacting badly together and sending out these packets due to the bug here: [grrr... apparently I'm not allowed to post links as a new user]
Regardless network traffic should not be capable of fully bringing down an Android System. All other devices even as old as the S2 did not crash under this load, why does the S4?
Hello. First, great forum- I can feel the love, as well as the collective genius at work here. It's refreshing to find a forum where people actually know their sh*t on a real, technologically advanced level. It's relieving as well, considering the headache that my new G2 is causing... as follows:
This is a Sprint device and I am still within the time frame to return if a resolution is not found.
Issue:
1.) While wi-fi remains connected (doesn't drop), it is terribly slow, averaging .8 - 3 mbps. Whereas, other Samsung android devices are averaging 15-20 mbps. Internet is cable, and I have reset the modem without experiencing any performance increase. (technicolor TC8305C, bgn)
2.) 4g is no better, averaging a mind boggling .5 mbps. (Don't even get me started on 3g- .1-.3 mbps)
3.) If 4g is even able to connect, which is rare... it disappears and and is nowhere to be found, or be (re) enabled.
Attempted (unsuccessful resolutions):
1.) Performed Sprint recommended troubleshooting techniques:
a.) updated profile
b.) soft reset(s)
c.) hard resets- multiple
2.) contacted customer care: received "refreshers," and was walked through numerous settings and performed various resets.
Recommended CC resolution: return device for exchange.
3.) Sprint store attempted to identify problem, and in the process found that their demo, along with employee handsets (G2) as well as new unboxed versions had the same problem. They offered to switch to an S4 or Nexus5 for free, or wait a couple days to see if the LG rep could offer a fix.
(further) Resolution: pending
Here's the deal- I think we can all agree that this phone is kick ass. Therefore, I would rather not switch, as I enjoy the experience it provides, as well as the satisfaction of getting to really bond with a device when troubleshooting them. Though, this phone seems to be pretty 'buggy,' and while I don't mind tinkering with computing devices (been seeing the blue screen since win '95), I'm not sure I want to be dealing with the potential hassle with a device we all rely on day in and day out to be our life blood... plus, just because I don't see/haven't experienced the other issues others have, doesn't mean they won't potentially manifest down the road. :/ Maybe the Nexus 5 is the better choice... but it seems like cost cutting has taken place in a couple areas- battery (2300), and the camera. Almost like the G2 is the flagship and the other is mildly scaled down in certain aspects even though the end result is compelling for both.
Please know that I am scouring middle earth low and wide for resolutions, and have not composed this post without first looking and becoming familiar with other peoples similiar experiences. I will continue to fact find, and I apologize for not reading all related threads before posting, but time is of the nigh, as I am still within a time frame to return in case the problem is inherent to this specific device (a lemon). Plus, I don't quite understand everything you're talking about, as I've never had/chosen to dig that deep into the obscure settings and techniques I've seen listed (and also because I JUST got it) Hence, the user name- g2 n00b.
So thank you in advance for your time in helping with this. It is both greatly appreciated, and not without gratitude on my part. Also, I hope I displayed proper educate by formating this post in a manner which is easy to sort through. K. let the trouble shooting begin.
also, to the mods- sorry if this is thread/issue has already been covered elsewhere. I also posted this issue on another board and nobody had heard of this problem, so I am fairly confident that i may be justified in having poted this. However, feel free to delete/lock/merge/ if I just didn't see it.. but please provide the link so I can further fact find, because I'm stumped. Thanks.
I just did a speedtest on mine (Also on Sprint) using Wifi.
Same speeds I get on my PC.
It's an oddball suggestion but did you disable the Sprint connection optimizer?
Optimizer enabled. Though, I have tried disabling it and running diagnostics to no effect- doesn't matter what I do, it still won't exceed 3mbps, unless I am lucky enough to receive 4g in certain areas.. then it's a 'blazing' 3.5mbps, but usually .8. I have msl code and have adjusted band priorities and still no difference there, including ##72786 to reset default connections to make sure nothing was adversely affected after investigating the issue.
I'm really bummed. I love this phone. I feel like everything I felt I was missing in the S3/S4 are present here. Love the interface, form factor and all of the settings. Maybe I should take Sprint up on there offer to get an S4 a Nexus 5, but I REALLY don't want to go back to caveman battery hog status on the S4 and have to purchase a backup. I imagine the N5 is more efficient in this area, but it still has a 2300 battery vs 3000 in the G2. Needless to say, I'm frustrated and confused.. but often times, such is life.
Any thoughts on the N5, or suggestions to further trouble shoot are greatly appreciated and welcome?
I have disable the connection optimizer and have done this http://forum.xda-developers.com/showpost.php?p=47423537&postcount=1
The only other idea I have is hit up a coffee shop and due a speed test on their wifi.
The sprint stores by me have crappy wifi speed hence the coffee shop.
I seem to have mostly resolved the issue. I switched channels and encryption protocol. Apparently, my g2 didn't appreciate AES very much. Has anyone else seen performance differences with their device when comparing AES to TKIP? If so, are they drastic? I would think AES would be fine with the g2, considering how advanced it is. I consider it to be somewhat unfortunate if I am forced to select TKIP just so I can get a decent connection. That is, unless of course there are settings I can alter in the ##data# screen that can make better use of this encryption. Is there anything I can do now that I have narrowed down the culprit?

What wireless router are you using? I use a D-Link at home and my G2 kept connecting and disconnecting repeatedly. I was able to fix the problem by updating the router's firmware to the latest version. We've never had any problems with other wifi devices on our router, so it seems the G2 has some unique peculiarities WRT wifi.
I'm running AES with no issues, but noticed following.
LG (Sprint) connects first with a slow 72mbps and switches after a while to a faster speed of 433mbps
I have an Asus Router RT-AC66R, if I play around on the router with Frequencies or the wireless mode, LG would go down to a slow speed.
Don't have Optimizer enabled.
I suspect your problem is a router problem and not the phone.
At work I've got a wifi network consisting of 9 Aruba IAP105 access points in virtual controller mode.
Sitting at my desk, with a Verizon Samsung Galaxy S5 on 4.4.2 I've seen it roam between the nearest two access points 5 times in two minutes. This issue isn't affecting a Galaxy S3 on 4.3.
The two closest access points have significantly different signal strength - the phone should connect to the stronger one and hold that connection, but instead it's constantly switching which makes the wifi connection practically unusable.
I've worked with support on the access points and they've basically decided it's a device issue since the logs show the phone removing it's own association from each AP. That combined with the fact that the issue isn't earlier versions of Android, iPhones, or computers leads me to believe they're correct.
There's also a Motorola Droid Maxx that's definitely affected, as well as a handful of other Android devices I can see in the management console for the wifi network but haven't personally inspected.
I've seen lots of threads of similar issues, with the most common fix suggesting to change the channel of the access point which isn't applicable here since these access points automatically select the best channel available and negotiate with each other to avoid overlaps.
Any ideas I could try or suggestions? Thanks!
