[Q] Help!

Multiple of times a day, my wife gets an "x" on the status bar of her mytouch 3g slide where the 3g internet sign and bars should be. After a minute or so, her phone reboots on its own and then establishes a data connection. Does anyone know why? Could someone please help? When the X pops up, she can't access the internet, can't get any calls, etc. It just says no service.

i have the same prob with mine. i found out that my SIM card comes free from sliding the phone open and closed and causes it to reboot. it happens about 1 every 2 weeks for me.

The X ,like you said, means your not in service range or in the coverage area that your network uses. Happens all the time when I'm at school or heading down to the country.
That's what the X usually means, but since you have rebooting issues the issue may be something else entirely. Seeing as I've never encounter this I can't be of help on that issue.

This used to happen to me on my old hd2. After numerous calls to t-mobile we figured out it was caused by an old, incompatible sim card. I have been with t-mobile for the last 6 years and when they started rolling out 3g, the sim cards they started using changed as well. If shes had her sim card for a few years look into getting a new one (they should replace it for free). Hope this helps.

Thanks guys! Much appreciated. She's going to see what the problem is next week. May even get a new phone or sim card.

4g service but no 3g?

This JUST started yesterday...
So, yesterday at work I noticed I had no data...so I did the typical restart...still no data...I shrugged it off and went on my way. As I was driving I had data again. I use wifi at home, so when I got home I didnt notice any issues and honestly kinda forgot about it. Well on my way back to work this morning I looked at my phone...had full 4g service...all seemed well. Then I got to my office...
Now let me explain I DO have 4g in this area but honestly...its only a solid 4g outside. Its not the greatest indoors. Well in my office I only get 4g if I'm standing at the window or one "sweet" spot at my desk. So 99% of the time I'm in 3g. Well to make a long story short my 3g antenna seems to be borked. I can pull 4g fine...on lunch today I was in 4g and it was working great. However, when I'm in 3g I get zero data...my phone doesnt work in 3g only 4g.
I called verizon and they just decided to send me a new phone...
I have rooted my phone and I have put the newest radio on. That was awhile ago though. Tonight I'm going to try flashing a different radio but has anyone else had this problem?
Again I get NO 3g service only 4g. In an area where 4g is spotty thats NOT good.
Thanks!

Yes, I had the same issue. The first Nexus I had gave me spotty 4G service and never went to 3G in the couple of weeks I had it. Amazon sent me a replacement which is rock-solid. I get solid 4G coverage where I should (my wife and several coworkers have LTE phones so I know where I should) and when I don't have that 3G kicks right in.
I think you should definitely expected better results with a replacement. Good luck.

I had chosen to use 3G over 4G to save battery life. After about a week with the phone I began to notice that I can hardly ever get 3G reception any more, even though 4G reception has always been excellent. I don't think it is a problem with the phone, but rather Verizon tinkering with its network.

I was having the same problem all day today.
I switch the phone to CDMA during the day and use the office's WiFi for data. However, I noticed today as I dropped my daughter off at school after lunch that I had voice only and no data. Her school is the first tower north of my office that doesn't have an LTE radio, so I normally just get 3G.
Not today.
I drove back to the office and I was able to get data through the LTE radio, but the data connection would go dead as soon as I switched to CDMA. I thought there might be something wrong with the CDMA tower, but two of my co-workers had Thunderbolts set to CDMA only and they were having no problems getting data connections.
I talked with tech support for a good couple hours this afternoon and they had nothing for me. Eventually I flashed the leaked 4.0.3 radios and CDMA magically started working again.
Did the new radios fixed the problem, or is it just a coincidence?
Hmmm...

I have been having the same issue since yesterday. Verizon said there is no outages in the area. I had no data all the way home from CT to NY and finally when I got home at night 4G worked. 4G was working in and out on my way in so I forced CDMA to see if that worked and I have been unable to get anything since. I have a new SIM coming today, but somehow I do not think that will solve the issue.

I've noticed this too. I was turning my LTE off thinking it would use 3g, but I'm noticing now that many times I either have 4g or no data at all.

I'm having the exact same problems and registered here to see what the resolution is. I'm apprehensive to root as I am still within the 15 day return window and quite frankly for 300$ I think this is total BS. Never had a dropped call, missed or unsent text on the 3g network on my old Dinc and I've lived in the same place for 2 years.
OP- could you keep this updated on how your new device works out?

same exact thing happened to me. I'm already on my second nexus and I didn't want a refurb or to lose root. So I flash android revolution hd , used tb to delete all my apps, and hid all signs of root including deleting su. I took it to Verizon and they gave me a new sim card. It was OK for about a day then started acting up again. So I called them from my wife's phone and they had to reset my number to the network and its been fine since

What do you mean by reset your number to your network? Never heard that term before

I'm not exactly sure, some techs don't know about it. When I had my charge it had no data. So they reset my number and phone to the network and I immediately got data back

(T-Mobile) Randomly Losing Signal

My gsiii for some odd reason loses 4G and sometimes even service. Last night when i was on a call, it dropped and the signal reflected that i was running on edge then it switched to someting that said "G." I looked at my brother's siii and he was also on edge. So i tried putting it on airplane mode however it would not go through. It's as if i never pressed anything. So i had to restart the phone and it was on airplane mode, so i took it off then about a minute and a half later i got 4G back. Today when i was browsing the web, i randomly lost 4G again but this time i continued to have signal just no data. About a minute later I got it back. About a minute later i lost it again and regained it about a minute later. I havent noticed anything else about the phone and ive had it for about a week and last night was the first time that i restarted it. Any ideas? Has anyone else experienced this? Thanks!

I'm also having the same problem it just happened to me today also and happened the other day when I restarted phone it did nothing then I did airplane mode that didn't do anything so I clicked the enable packet data off then on an item came back in hoping it's not going to be a hardware problem cause I've dropped calls for no reason and had no service or bars were showing but had no edge 4G etc

Yeah it's really weird, when I was using mt4g, it would do that randomly as well, I'm not sure if it's a phone or a network issue. Anyone else experiencing this random drop in data?

Same here I think it's a common issue with tmobile devices.

I think is just the network it had happened to me but while driving some place and Idk if is the coverage but other then that I do see going from h+ and 3g, I have a custom theme install

I just moved from Sprint to Tmo and I'm getting the same on my S3. It would look like i have good 4g coverage with 3 bars then all of a sudden it goes to Edge. So I have to wait for it to go back to 4g to start surfing. Edge is like 15kbps for me which is not even modem speed which is 56k. If I accidentally start surfing on Edge it seems to wanna stick to Edge until I close whats using data then it will eventually go to 4g. But when I get 4g its awesome and I get over between 6meg to 12 but only 40% of the time. I called Tmo and they said I have great 4g coverage where I'm at....ya sure.

I've only experienced outright loss of signal once, which was last night. So far nothing else has happened really. It was just odd that my phone won't even go into airplane mode until I rebooted the device.

Same thing happened to me. I was actually quite worried and about to send my phone back. Everything seems to be working okay now. No issues.

this has driven me mad for the past few days. recently I upgraded to a S3 and my dad got a S 4G (which was released 2 years ago). while we were in Costco, my S3 randomly switched to Edge while the S 4G has 4G all the time. ALso we were on vacation to San Francisco so I could experience "Tmo largest 4G network." While we were in a hotel in Fremont, my S3 again switched to Edge and back to 4G randomly while the S 4G had 4G. also the signal is not stable at all. sometimes(1 or 2 times) it even dropped to zero bar. SOMETHING wrong with samsung phones. I read somewhere someone had this issue with the S2 also. I can live with the HSPA+ for 2 years, but hey dont give me random Edge like that
I plan to go exchange for a new phone at Costco... probably a new S3 to see if the issue still exists...

T-Mobile's 4G network works in a interesting way (do all HSPA+ networks work this way?). They idle in UMTS mode (3G) until there is network activity, and then switch to HSPA+ (4G) mode. The network changing is an automatic thing does to save battery life ("Cellular standby" is often the largest battery drains).
Ever use an AOSP-based ROM (i.e. Cyanogenmod)? You'll sometimes see the network indicator in the status bar switch between 3G to H+ to 4G, etc as you use it. Stock T-Mobile ROMs are hard-coded to always say "4G", but if you go to Settings → About phone → Status, you can watch the network type there change as well as the phone does anything over the cellular network.
You should never be dropping to GPRS or EDGE. Perhaps the mechanism described is defective on your phone?

Happened again today. Had signal but no 4G, not even Edge, just bars. i think it happens whenever the signals low. Thoughts?

I'm having the same issue at my work place. I'm getting Edge (50-80%) more often at my desk, when previously with my SGS2 it stayed at 4G all the time. Checking Cellstandby I am getting 31% time without signal.
Is there a setting to force 4g connection?
My office is in Cupertino, CA and reception is not bad in general, but there are a few locations with 4G dead spots.
I'll check my reception again at home (Santa Clara, CA). I can do a side by side comparison with my SGS2 (now belongs to my wife).
On call with TMO right now, they are going to do a reset of the phone in their system, then I will need to do a reboot. Fingers X'd that things will improve.
BTW, what options do I have to get a replacement phone if I bought mine from Walmart? Do I need to send it in or can I do an instore exchange? Just got it on Sunday. Will I incur any fees if I returned the phone?
---
Reset didn't work. Passed on to level 2, there submitting a service request to check reception in the area. Need to follow-up on Friday if the reception is still bad. Since I'm in Cali I do have 30 days to return the phone.

I have similar reception issue but I dont lose signal completely. I will go from 4g(hspa+) to 3g to edge then it will switch back to 4g after 30secs-60secs. Quite annoying since I will be stationary and it will happen and it happens more when Im in a car. Never had this problem when I had the Nexus One.

Question. With your s2 what happens if you're in an area without 4g? Do you get edge?
Sent from my SGH-T999 using Tapatalk 2

I am having the same issue. I had perfect 4g coverage all over my town, (I live in south texas). The problems started 2 days ago, when I lost all 4g coverage. I took out my sim card and placed it back in and the 4g logo came back on. But now I have been noticing that my cell signal will completely drop and then slowly come back up. This has happened several times. I also went to tmobile and changed my micro sim card and the issue remains. AND NOW I AM ON EDGE!!!!!

Has anyone been able to get a replacement and did it fix the problem?

Rooting issue or just coincidence?

Hey guys, I just a sprint gnex phone a few weeks back and ran the GNex toolkit v9.1 to unlock and root it this past saturday so I could use a hotspot app for my tablet.
I don't know if this is just a bad coincidence or if I did something wrong..I'm not new to roms and have modded my previous phone (evo 4g) about 50 times, but here's what's happening.
Prior to this weekend I had full signal/bars..Now I can barely get 2..It's mostly sitting at 1 bar and sometimes drops the connection entirely. At the same time, every txt msg I send comes back with an error stating it did not send, however...It does actually go through, twice even. This happens with every text to every person.
I didn't put a rom on it, and I didn't even install clockwork mod...I simply just unlocked the bootloader and rooted it. I did setup google voice afterwards. I can't see how doing this would cause these kind of issues and I haven't called Sprint yet as I absolutely despise their customer service..I'd rather get feedback here first.
The coincidence that I'm referring to is that I'm in Austin, Tx and they're in the process of spinning up 4g LTE towers right now..If by chance they started upgrading my tower this weekend (yesterday & today) then I could definitely see these issues...I walked down about 2 blocks where I do get a full 4g signal, but my txting still had the same issue.
Any ideas or thoughts about my problems?

On one hand, I would tell you that rooting doesn't cause that.
On the other hand, you used a toolkit, so who knows what you ended up doing.

If you haven't changed anything as far as ROMs or mods, then I would suspect you're right about something with the network. The only other thing I can think of would be hardware problems of some kind. That seems a lot less likely though. Sprint does supposedly keep a list of networks that are being worked on. You could check in with them and see if the one in your area is being upgraded.

I do know they are upgrading the towers in my zip code to LTE 4G..I'll give em' a call tomorrow and see what they say.
This was the toolkit that I used.

happened to me.
Reboot your phone and go to about and sprint system update.
update profile.
Idk why but its sometimes happens for no reason.
Make sure you have good connection first.(go outside)
If that doesnt work update prl to make the network find the closet tower to you.

I was trying that repeatedly hoping it would fix it..but it doesn't.
On another note, today when I woke up and rebooted the phone I had full bars on 4G signal..Thought life was good and then about 5 mins later it was back to 1 bar 3G. That's the first time I've seen a 4G signal here in my apartment so I'm hoping it really is just the towers in my neighborhood being converted to 4G right now.
I've rebooted my phone 3 times now and the same occurrence happens..Full signal with 4G for a few mins, and then it drops to 1 bar 3G..Have updated my profile and PRL and tried airplane mode..Only way to get that 4G signal back is to reboot the phone..Won't stay on 4G though.

Data Issues Maybe?

Not sure what to make of this. I'll be somewhere, usually indoors but not always. I know there are some places indoors that you can barely get a signal (I usually go by how many bars there are in cases like that). But I'll grab my phone, lookup something on the internet, or check flipboard and no data at all.
The status bar will show 4G LTE with the little orange things going back and forth. Sometimes I can reboot the phone and it will work but more often than not it doesn't Just seems weird that if I can't get data, why is the 4G icon acting like there's no problem, and why can't it revert to either plain 4G (HSPDA+) or even 3G? I'm on the stock rom, rooted.
I live in Southwest Houston, TX, and rarely go out of that area so I don't know if it's a local problem or not. On that subject, I was in downtown Houston last week and was told that nobody's data will work there which seems very odd...?
I'm thinking maybe I need another SIM card?

anyone?

I had the same problem on my gs3. I called att they just had me reset the phone and disconnected me from there network then put me back on it.. Still had the problem. att sent me a new gs3 after that.. Same problem. I now got them to upgrade me to the note 2 . Love this phone.. Also has the same problem and i am on a new sim card with this phone. Its not as bad as the gs3 but the problem still happens. I am in Denver , Colorado.

It the network in Houston it has to be. I am from Louisiana and was in Houston all weekend and had problems non stop and battery draining very fast. I have had no problems in New Orleans or outside of Houston. Most of the issues are in downtown.

This happens to me also. Inside my house, I have poor coverage and this will happen to me even sometimes when the phone shows 1-3 bars of signal. Can't sent a txt message or anything. Sometimes it will start working again in a few minutes... sometimes I toggle airplane mode to make it work again. Frustrating!

This happens to me sometimes, but only with sending and receiving mms. I'm in Dallas, but it also happens when on our microcell. We're on our way to Houston right now, so this should be interesting. Partner's mom says gps/google maps is useless down there. Ugh.
