[q] no coverage - General Questions and Answers

I have a problem with my Samsung Galaxy S4 gt-i9505.
A month ago I broke the outer screen - it didnt affect the touch screen - and I sent it to my phone ensurance (which I think sent it to Samsung then) for them to repair it. It came back looking like it was brand new, but now it gets no coverage.
I have no idea what would make my phone behave this way: now coverage appears just twice a day (if it does), for just a few minutes, and then it vanishes again. Despite that, Wi-Fi works perfectly. I have already checked if it has to do with my sim card, but it works perfectly on any other phone.
I suspect it has to do with the fact that my ensurance changed my mobile's OS (which was the latest CyanogenMod) to the default Samsung Android. IT MUST HAVE BEEN THEM!!! I have already installed CM, but the phone keeps behaving the same way... I have also checked if the phone's EFS data aren't lost and they aren't.
I have no idea what to do now with all this, but I don't trust these ensurance guys any longer and I'd prefer to fix it by myself (if possible) and avoid waiting another month without being able to use my phone. I am too pissed off.
If anyone can suggest any possible solution I'd be REALLY grateful. Thank you anyway to all those who read this.
PS. I live in Spain and my phone company is Yoigo, with whom I have a two-year contract (only one remaining). It was this company who gave me the phone (it wasn't unlocked). Just in case these facts end up being useful. Thanks again.

Hi, I know you don't want to here this but the best thing to do is send your phone to them because if anything goes wrong it's their responsibility. It sounds like they've broke the Cellular chip or the antenna.

Questions

So I got my XT720 a few days ago and am loving it. Two things though:
1) I've had to do a quick reset (take out battery) about 4-5 times in the same amount of days. What happens is sometimes the screen will go blank (or when I press the on button all that will happen is the 4 buttons at bottom of phone will light up). Screen/phone becomes unresponsive and only way to get back to normal is to take out battery. I'm pretty sure that every time this has happened has been right (or shortly) after me downloading something on my phone (i.e. putting on a new wallpaper, or a song). Anyone have this happen to them?
2) I don't want to root or put on Dexter's ROM just yet. The reason for this is because a) I just got my phone and I don't want to void the warranty until I know everything works with no issues b) I'd rather wait for the complete/fully polished version of the ROM - I'm in no hurry right now, this phone is a big big upgrade from my previous phone even without 2.2.
Anyways, the point is, I'm pretty sure my phone isn't running with the 720MHz update right now and is running at 550. I want to put on that update to make my phone faster while I wait to root. However, whenever I go to - about phone - check for system updates - and click on that, it always tells me "Server unavailable. Try again later.". Been trying for the past few days and no luck. How can I get the 720MHz update (without rooting - at this point)?
Thanks
If the screen doesn't come on when you turn on the phone, you may have a defective one. My first XT720 was a dud right out of the box. I had to take it back to the Cincinnati Bell store and get it exchanged. I've heard of other people having similar experiences with the phone not turning on. Take it back. If they give you any crap about it, just tell them that the Motorola tech from their forums told you to take it back. This adds a bit of validity to the problem and may make it an easier transaction.
Nah, it works fine for the most part. Turns on and off and runs just fine normally. But my issue is I've just had it basically freeze up 4-5 times in the past week (noticing a possible connection to me downloading things).
I would think your phone is running at 720mhz. I believe the European / Asian versions were originally 550mhz & had an ota udate to the 720 level. You could download Android System Info or Elixer to check it out though.
I would also agree with reverendkjr, it the phone is acting funky take it back & get a replacement.
The XT720 from Wind is 720mhz with stock firmware, the only 550mhz was Korean version AFAIK, maybe some Euro versions.
As for the screen, you may want to try doing a factory reset on your phone. If it persists after that take it back to Wind for a replacement, had my wife's XT720 replaced due to a microphone problem.

Oh? I figured it might be at 550 since going back to homescreen - it reloads pretty often (thought 720 wouldn't do that), though it does run snappy enough in all other areas.

Be a bit of a pain to factory reset at this point. The problem isn't terribly disruptive at this point. Doesn't happen often enough to really bother me and restarting is quick. If it does continue and become frustrating I may consider factory reset. I just was wondering if anyone else experienced this.
WIND would give me a replacement at any time (within the year) if I told them about this issue? (Kind of hard to prove since it happens at it's own whim. Don't want to seek a replacement just yet anyways - not unless it continues and is an annoyance)
Just put a call into support so they have a record of the problems, explain to them you cant reproduce the problem, but it is a brand new phone and should not be doing this regardless.
They will suggest the reset to see if the issue persists, but you can decline at this time and at least get the issue logged so you have a better chance of replacement in the future.
Keep in mind though, within 14 days they will replace with a new phone, beyond that you may get a used one.
I can't imagine just ignoring a problem with a new phone like that. Especially since you have the ability to have it replaced for free.
Heck, I took a phone back once because it had ONE dead pixel on the screen. When the girl looked at me and said "Really?" I said "Hell yes, I just bought this damn thing and I want it to be PERFECT!"
you need to setup the APN to connect to 3G to get your 720 upgrade from OTA (if purchased unlocked Euro or Asia models)
if it's a Wind XT720 it should already be on 720

Yeah, I suppose that's true. If it happens again I'll look into getting it replaced.
Thanks for the help guys.
my XT711 has done the "blank screen a few times also and I have to remove the battery to reset it. Very strange thing, but I have had the phone for only a few days so im gonna see what its gonna do first cause sending it back to china is a pain in th butt.

[Q] Bad ESN Mesmerize, few questions

So I got one for $34, delivered today. Looks perfect other than a couple scuffs on the bottom corners. The seller said it was working fine (despite listing saying it was for parts/not working). I don't have any usable cell service where I live without getting a booster and antenna of some sort, so I don't care about activating it. I plan on using it basically as an internet tablet to check email, etc.
I do not have an sd card, charger, or data cable yet, they should come tomorrow. Since the battery is close to dead, I can't find out much. It turns on fine, gets to the home screen and has that "too many pattern attempts" screen (screen looks perfect, not a single scratch by the way) with the google login. I know not to try a full hard reset with the battery being about dead, but I have tried to bring up the menu option so I know how to get there when I do get it charged. I have tried every key combination method I can find with no luck, keys ~seem to all be working from what I can tell, read in the comments that a few people had no luck. One time I got that screen with the android and shovel, waiting for download. I was wondering if that is from the factory, or if that means it's been rooted?
Basically, all I really want to do is restore it to stock for right now. Maybe something better down the line, I'd just like to use it for now since I've never even really seen a smartphone before, because nobody has one with the poor cell service here. I have the EE19 build downloaded, and I see the restoring to stock thread. I want to do it the right way. So, if it has lagfix installed, I see I need to disable that. Any other things I should know about? I was just wondering if it sounds rooted, if I need to do something else if it is. I don't have a lot of time on my hands to do research, although I did a little already, and I have a very limited internet connection so I can't download a lot of things, I wasn't expecting to need to do this when I communicated with the seller.
Thanks for any advice or tips.
Edit: I was also wondering the best way to go about checking the ESN, or if I should try. Like I said, I don't care to activate it on US Cellular, but if I'd resell it or something. I know I could use PagePlus, but the Verizon tower is 30 miles away, so not much chance of that working well either. I don't think it should be stolen or anything, but was thinking if the account ever got settled or anything....
Well I got it, posting from it now. Only problem is unsuccessful download errors in app market, after download is almost complete. On wifi. I tried every solution I found for that with no success. Other than that, no problems.
Tried every fix for the market, deleting cache, changing permissions on vendor.apk, etc. Seeing it was a common problem with few solutions that work, I flashed CM7. That worked great, apps installed fine, but of course wireless cut out constantly, not usable for long. Saw that was common, tried everything with no luck. Went back to stock, then airplane mode, now market works fine. It fails whenever not in airplane mode. So I'm sticking with this for now.
Can't activate anyway, but best I saw was -104db, but mostly no service. My LG tracfone does a little better with reception.

[Q] Frustrating One S sensors locked?

Greetings all. I'm not convinced my problem is specifically related to the One S, and I certainly haven't got anywhere near rooting yet, but you Guys are expert at nosing round in the bowels of this phone & the OS, and I'm getting totally flummoxed as to where I've gone wrong.
I've owned this phone since June and it was originally locked to O2, was unlocked and used on Giffgaff, an O2 offshoot - probably irrelevant. One of the apps I particularly wanted to use was Google Sky Map, duly installed and run successfully for a day or so. Other apps installed, as one does, but when I came back to Sky Map, the app was frozen, as were seemingly all compass function apps.
Various uninstalls & reinstalls later, a system reset and a factory reset and this function still was inactive. Returned to HTC for fixing. No better - all worked OK for a short while then stopped. Returned again and this time internals were swapped ,but now the microphone wouldn't work. Third return and an unlocked sim-free handset was returned.
As soon as I loaded my profile from Google, initially it worked, but later most of the sensors again seemed to fail. I've tried the full factory reboot then logged in with a totally new Gmail account, but no change. Phone Tester app shows only readings from proximity and light sensors - no gyroscope,compass, mag. field or accelerometer. Accelerometer did show one set of readings this morning, but nothing since. Lookout AV has always been installed. Incidentally, almost exactly the same profile worked perfectly well on my previous phone, a Wildfire S.
Should I shoot myself or the phone? I admit I'm not any sort of phone expert, but I don't think I'm that dense as to so consistently screw this thing up.
Any ideas people please, in (moderately) simple terminology?
Ok maybe you could shoot google, maybe its a fault by them.
If I helped in anyway please hit thanks
Thank you for the oh-so-helpful response.
Just in case one of the myriad readers of this thread should have just a quiver of interest ................. I believe I've found the answer.
It's always been difficult to pinpoint the problem, and certainly HTC haven't twigged what's happening, as before I sent the phone back to them I TOOK THE FLIP CASE OFF!
That's why it would work for a short while after return, until I replaced the case. I can only guess there's something like Carbon Black in the plastic back shell, and that's what's been interfering with the sensors.
It may also be relevant to the big Home Button problem, with the screen flipping between Home & Helicopter views. Has anyone investigated whether there could be sufficient signal degradation to trigger this problem caused by the use of a case?
Sweetness and light to all.
I spoke to an HTC rep, and he said they would not give an unbranded handset back. If that's the case, I want my phone unbranded. I'll take it to them and hopefully get an unbranded one.
Well good for your HTC rep. They can't go giving out unbranded sets like that. What is the World coming to?
Notwithstanding - the previous clutter of O2 apps was pleasantly noticeable by its absence as was the O2 splash screen.
What a lucky little customer I am and it's only taken 4 months to sort out.

[Q] [HELP-Stock ROM] Google Nexus 5 cell radio off. Cannot Make Calls, SMS, or Data.

Hi guys,
I've been a lurker on XDA for quite some time, and I just want to say, I absolutely love you guys. You're all very helpful and so knowledgeable. I can finally say I have an issue, I'm hoping is a software issue only, that I need help with.
Last week I was running Stock Rom Lollipop 5.0.1 on my Google Nexus 5 and now I cannot get a GSM signal AT ALL. No Calls, No SMS, and No Data. The same SIM card can work just fine on my unlocked Nokia Lumia 635. I am long past my RMA. What can I do to try getting the GSM to work and TURN ON MY GSM RADIO? I'm sure if the radio turns on, everything else should work as well.
Brief History: Phone has been dropped on cement before and got Screen replaced. My internal speaker got loose and I just got it readjusted by a nice technician near where I live. I've survived with this phone from Day 1 until now with some cosmetic wear-and-tear, but it was only from last week before I left work, AFTER I UNPLUGGED MY PHONE FROM THE WALL SOCKET that the GSM signal just dropped.... permanently. And what I mean by this is, the "radio" is off permanently (I cannot turn it on even with the option in *#*#INFO#*#* with SIM card inserted) even after reboot, airplane mode on/off, and APN setup (which can never be saved and hangs when selecting automatically 'detecting'). Note: The Phone can charge just fine and connect to the computer perfectly fine as well (in case you guys think it may be related to the microUSB port assembly). I have been taking out my SIM frequently, so I'm still not 100% sure if it is or is not my SIM Card Reader pins that have an issue.
I have fastbooted several factory images on this device many times from the Google factory images repository, mainly going back and forth between 4.4.4 and 5.0.1 which I believe are the best releases so far IMO. Even after installing the factory roms on this phone, (no root) I still get no signal no matter what I do. When I remove my sim card tray from the phone, I get "No SIM Card". When I put it back in, I get that message going away, which gives me the impression the SIM card reader is fine. My technician took a look at the entire phone hardware and said he didn't find ANYTHING strange. He tried using a known working back-cover with antennas to debug the issue but that didn't help. I don't remember what he said about the sim card reader, but I think that was also fine (will double check next week). When I got the phone back from the tech, he just told me that there are no "hardware" issues he knows of, and so this must be "software".
Any leads you can give me? I'm pretty tech savvy, and do understand things like partitions, fastboot, adb, etc, so any solution, even abstract, I'm willing to try. Google reps were pretty clueless on helping me out here, so I'm looking for some support, please!
I've also heard that this issue is not uncommon on Nexus 5. Is this true? How many users have been having this issue? I thought Nexus 5 should have been built great to last a long time... guess I was wrong.

Same situation on my Nexus 5 that started a few days ago. Thought it had something to do with the 5.1 Lollipop update and saw some users were having similar problems. Tried flashing different radios/basebands/roms/kernels to no avail. Currently running 5.0.1
Hoping it is not a hardware problem, going to take it to a local technician today. Also beyond warranty. Everything else works fine. Has always been in a hard case but dropped a couple of times with no prior issues. Any insight?
5.1 is the best software. If it's not hardware all I can suggest is a full factory reset. My SD card was not acessable and pple said try this and that command. No luck. Did a factory reset and got the SD back Oh and screen shots which had gone as well.

Keyboard issue on brand new and warranty replacement - long time returning user

Hi. I'm not your typical noob person, I simply haven't had an issue I couldn't find a solution for that required me to come to XDA in a very very long time.
Long story short, I got the Galaxy S8+ 5G tablet brand new from T-Mobile in less than a week.. immediately noticed issues with swiping/glide on both Samsung and Gboard keyboards(Gboard is my STRONG preference for a long time now)
This is brand new out of the box, before a screen protector was added or any apps installed. Still did all the standard trouble shooting - installed update, no dice. Force closed each keyboard, wiped cache and data on each keyboard, tried turning sensitivity off and on and.. no dice. Restarted into boot mode and wiped cache.. most of these things not really something that should apply to a brand new out of the box tablet except update and factory reset - both of which I did, neither of which, nor anything else has helped.
I even added a tempered glass screen protector thinking it's TOO sensitive, and even after that, and again trying to toggle sensitivity setting in the settings.. still just will not swipe.
I type this currently on my Samsung Galaxy S20 FE5G absolutely flawlessly. I can type without looking at the phone at all and type near perfect accuracy with just the occasional need to choose a different word in the suggestion bar.. that is using Gboard "glide". The tablet using Gboard bloating mode is almost an identical match to the size of this keyboard and would make it a nearly *perfect* way of typing just as quickly and accurately on the new tablet.. I understand that some of the accuracy comes from use of the keyboard and locally stored into but.. the tablet types gibberish half the time. If I push FAR harder than I should have to while gliding, a few words may work.
Called T-Mobile Saturday, had a warranty replacement sent(God I didn't want a refurbished device) because the only natural conclusion I could come up with is the digitizer has an issue, maybe during shipping.. etc. I don't know..
Got it last night, booted it up, this time I made them include a "invisible shield glass fusion+" screen protector which went on flawlessly and should have no effect on typing at all.. and it's got the same EXACT issue. Maybe a HAIR better, but still completely unusable in my opinion.
I want this for work, the tablet and this phone and a 4k Chromecast, with features like dex, second screen, etc.. there's just about no scenario I can think of where this WON'T be beneficial in any support scenario..
T-Mobile already wants to give me the tablet for free, I've had so many issues with them for so long they switched me to a "business select" package only certain managers can apply, and I get unlimited everything for each device at $25 per device.. forever. No matter how many.
No discounts for auto pay or mass numbers or.. just a flat number that beats the company I was going to switch to when I unlocked my phone 12 days ago.
But I've been a customer customer for 8 years and a T-MOBILE customer since before the first iPhone smartphone was released.. even a few years before that when the best phone you could get had a slide out keyboard and basic touch functions..
So they are supposed to be calling me within the hour, I expected to see numerous threads or posts about this issue, because clearly it isn't ME..
I find some other links I've tried fixes from like:
Strange Gboard bug temporarily breaks glide typing, here's how to fix it [Update]
Over the past 24 hours or so, users have started noting a strange issue with Google’s Gboard keyboard on Android,...
9to5google.com
And see this post of Galaxy phones describing exactly the same issue
https://www.reddit.com/r/GalaxyS22/comments/u8y4cz
and describing it happening with a specific update..
I've got 2 devices, the first is brand new and factory reset as of last night, has a glass screen protector, and the refurbished one in front of me with the same issue.. I've restored data so I can continue using it, but tried all the SAME fixes and nothing.. and T-Mobile is calling in 45 minutes or so.
Obviously I'd like to keep the brand new device rather than the refurbished one- but IS THERE A FIX, or anything I can do with them on the phone.. I got a Bluetooth keyboard and mouse and aftermarket case.. I can type using the keyboard obviously, but I typically can type WAY faster with Gboard the way I am on my phone right now..
I tried doing searches on XDA but it seems like their search functionality has changed for the worse in the years I haven't been here.. that or I can't find the advanced search and forum search I KNOW I used to use daily.. not in the app, the mobile page, or desktop version.
And because it isn't worth it's own post I'll ask one more question -originally I had them send me a Galaxy tab 7 FE 5G becauseb the S20 I'm using still works so well and it was only $100 if I added the line.. and it's just an oversized worse version of my phone.(but don't recall it having this issue now that I think about it) Which is why I'm here now with this tablet..
The problem created by that is I can't tell the pen for that tablet and the new one apart, and here https://m.gsmarena.com/compare.php3?idPhone1=11342&idPhone2=10922# it is showing the new one has less latency, Bluetooth, etc..
Part of the reason they are calling this morning is they were like "oh, just keep the Galaxy tab 7 for free, on us"
Me: "I don't want that oversized garbage, that's why I'm ordering the 8+!"
T-Mobile guy: "Oh, well then return the 7 and you can have the 8+ on us!"
Then I've been trying to get a shipping label for 11 days now, only to find out that he never put in the system that I wanted to return the device and he already voided out the equipment plan for it.. meaning I'm stuck with a tablet I don't even want- and can't tell which s-pen is supposed to be the better pen!
I mean, the chance I'll lose one is so high I won't return the pen and keep it as a backup.. but.. I'd still like to know how to tell the difference, when I attach either one it connects with no issue and I can't find anywhere that shows the pen type connected!
I'm so sorry this is so long, but like I said.. I normally do not need to come here and get my issues resolved myself, it's what I do for work.. and I haven't needed to root/rom a device in so long that I just kinda.. stopped.
(But I'm not going to lie, I got super excited when I came here and there seems to be the option to root/ROM and that it seems like a well supported device in that way! I've kind of dreaded KNOX because previously I never could.. but I'll look into that later once I fix my CURRENT issues..!)
Best I can do as far as pic of S-Pens https://photos.app.goo.gl/pfqKMiiG49L21gx7A
