[Q] Bought Used & Has Problems - What Should I Do?

Hi everyone. Just to start out, I am completely new to the Android world – I’ve tried to read up on these forums and whatnot but I am definitely a noob. I am coming from Apple, and long story short, I’m tired of iPhones and got myself a Galaxy S3 via Swappa in order to keep my unlimited data plan. It was previously rooted, but I requested that it be restored to stock.
I have been unable to get to a Verizon corporate store to get a sim card and activate the phone, so I’ve been using it on wifi around the house. I am having signal issues with the wif – it works everywhere except in my room. The signal shows as weak and keeps dropping every few minutes. My other devices have a strong signal. I have downloaded various wifi analyzer apps from the Play store, and they all show the wifi signal as really weak.
I searched and found numerous threads that this is an issue with some of the phones. I tried messing with settings (factory reset the phone, the router, did the *#0011# and turned wifi power saving off, changed the "keep wifi on during sleep" from always to never, etc) and nothing fixes it.
I would like to know what you guys recommend. Should I go ahead get a sim, activate the phone, update to Jelly Bean and see if that fixes the issue? I am unable to get the update since I do not have service. I tried to update via Kies, but it says current firmware pda:lg1 phone: lg1 csc: lg1 (vzw) not supported.
Or should I tell Verizon about the problem and see if they will go ahead and replace the phone? I’m not sure how that works since I am not the original owner. I’ve read that they honor the warranty based on the purchase date which is tied to the IMEI number, and not the owner’s name. Not sure how true that is… Also on the box, it says Verizon 4G LTE Certified. Not sure if that means my phone is already a certified replacement or if all the boxes say that. I haven’t been able to find that out.
I’ve read the thread about resetting the phone to return to Verizon. The flash counter screen reads Odin mode, product name: SCH-I535, Custom Binary Download: No, Current Binary: Samsung Official, System Status: Official, Qualcomm Secureboot: Enable. The android version is 4.0.4 and the baseband is I535VRLG1. Does it matter what the kernel, build number and hardware version are? I’m not sure what they should be.
I just want to be prepared when I walk into the Verizon store (which is unfortunately over an hour away), so I’m hoping I can get some opinions and maybe save myself multiple trips. I’m not sure if Verizon will work with me or not, but I figured you guys are the experts and can help me out. Thank you!

It looks like the guy who sold you the phone did in fact fully return you to stock. But it is fully stock based on the oldest stock firmware (I535VRLG1). My advice to you would be to activate the phone, and grab the OTA updates all the way up until the current version (I535VRBLK3).
I used to have all kinds of WiFi connectivity issues with this phone, until I replaced my router. Now it works perfectly. There was no real explanation as to why that was, but this phone does seem to have WiFi connectivity issues, especially with older Routers.
Try updating your software first, and see if the problem resolves with the new firmware. I believe Verizon does base the warranty off of the phone activation date, at least they did years ago in the past, but that may have changed.

Thank you, I appreciate the reply. I read that there was an OTA update issued around October to fix some of the wifi issues, but I wasn't sure if I had it. Once I activate the phone with the sim, do you think there will be any issues receiving the updates? I know nothing about rooting and have been trying to read more about it, but I'm concerned I'll end up causing more problems with the phone before I even get to use it.
The router I have is a free one Verizon gives to use with their dsl service - a Westell Model 327w. It is pretty old, although I think the firmware is up to date. The phone works fine when it is closer to the router and everywhere else in my house, except my room which is upstairs and at the other end of the house. I just figured since my other devices work fine, the S3 should too.
Thanks again.

If you are fully stock, with the stock recovery (which it sounds like you probably are), you should have no problem downloading and installing the OTAs. I believe you will have to take a few them before you get up to the current version.

I can confirm that the stock Verizon GSIII has a few upgrades before you get to 4.1.1 (the latest version)

Thanks guys.
I just remembered that I have a newer router that Verizon sent me, but I never bothered with it because the current one was working. I'll try and set that up and see if the signal improves.
I am hoping to get to the Verizon store soon, but unfortunately things keep happening that prevent me from making the trip. Can't wait to get this phone working though. Just the little bit I've played with it makes it difficult for me to go back to my iPhone.

This is how a noob post should read. Nice job, OP -- very informative and you did some homework.
Other noobs take notice -- this is how you do it. Notice how much help he got?

If its any consolation, I had wi-fi issues even with a newer Verizon router all the way up to the latest version of the the modem and rpm file (vblk3). With the last and latest (vblk3) update, those problems disappeared. So as stated, I would update the software to the latest and hopefully you should be good. Just to add, my wife had the same problems (same phone) as well so this validates for me that it was a software issue.

[Q] Losing data/voice connections....

So, my wife bought this phone a couple of months ago, and for the most part she likes it. However, she does have problems with the phone loosing voice and/or data connections. She uses the Sprint Zone to check, and often times one or the other has failed. After the first time this happened, I spent a lot of time with sprint getting the phone refreshed. Eventually we returned it for another one, but are still having the same intermittent problem.
We have found out that putting the phone into airplane mode will reset the radios and it works again, but eventually we loose one or the other.
So, do others have this issue, and if so, what did you do to fix it? I looked around (albeit not as hard as I could have) but I haven't seen much on this....
thanks!

yep, i have this happen sometimes, but haven't found any solution other than what you said: toggling airplane mode. and the issue seems to have persisted thru software updates.... although the latest official asa14 release seemed to be decent, the main problem i had was when switching from cdma/lte to cdma or vice versa, i would have to toggle airplane mode to get it to reconnect.
on the JB soak update, i've seen data seem to be connected, but no data will load at times.

I believe that its been stated that until official lte launch that the different signals will not handshake properly when switching towers, but that may not be your situation.

ok yeah, i believe the launch became official a week or so ago in my area, and the transition does seem to be seamless now.
another thing i see is the 3G icon and signal bars randomly turning white(instead of blue), and no data loading. but to be fair, that is on the JB beta test build..

Thanks for the input! I'm not sure if it's switching towers or not, I think there was at least one time that it was. Denver doesn't have LTE yet (supposedly, the Sprint Call Center in Centennial does, haven't confirmed or denied yet) so I can't test that. We'll be in KC next month, they do and I'm planning on checking it.
I'll keep an eye on it, and report back. Hopefully she gets JB soon... there's a lot of cool things with it I'm showing her she can't do.

I live in the chicago area and we got LTE a few months ago and I did have this issue for a while but as the rollout of the new equipment went along and more towers were updated i had it less and less. Dont seem to have it at all anymore.

Cool, thanks! No clue when Denver is getting it, if ever. Could be tomorrow, could be two weeks before 5G is rolled out....

I use s4gru.com to keep track of when rollouts are hitting.
Colorado appears to be Q4 2013 - but I don't think that is going to be accurate, that is just the original plan...

Yeah, I've been watching that site. They have a colorado thread there that I have bookmarked....
I'm just a cynic.

Interesting findings on the newest OTA (MD3)

I read about all of the issues people are having with the newest OTA (MD3). I decided to give it a try anyway, because I love writing emails to Verizon pointing out their flaws.
I followed the instructions in this thread: http://forum.xda-developers.com/showthread.php?t=1762709 to go back to stock, using the Official VRALG1 4.0.4 Firmware. I wiped the Data and Cache partitions after installing. After this, I applied each patch in succession BEFORE installing any other software or programs. When I was done, I immediately disabled the Caller Name ID app. I have NONE of the reported bugs:
* Texts send immediately on the first try
* Battery life is no different than it was on the last firmware
* Phone switches easily between Wifi, 3G, and 4G LTE
* 4G LTE speeds are normal
I am no stranger to unlocking, flashing ROMS and Radios, etc, but I am most certainly NOT a dev. I'm posting this information here so that someone with more knowledge than I may be able to glean some information useful to those that ARE having a problem from this post.

I was having issues with the ota and I went back to the oldest update then took the otas.
Then rerooted mb1 and flashed bonestock 2.0 with the mb3 radio/modem....still had signal issues. And that rom has all bloat removed. So I flashed the mb1 radio/modem and now I get better signal.
Ha thats my story.....definitely a mess up from Big Red.
Sent from my SCH-I535 using xda app-developers app

I wiped and then installed the stock deodexed MD3 ROM and firmware and had data issues...low signal, frequent drops to 3g or 1x, etc. Ran it for a few days and it was noticeable wherever I went. Restored my CleanROM nandroid and flashed the MB1 firmware and my signal has been much more consistent again.

I was weary of the rumored issues so I completely wiped my internal storage for a fresh install, and MD3 has been nothing short of amazing for my phone. If anything the only knock on it is that the signal has degraded about a bar in areas where I'd normally have full bars. Data connectivity is fine, data speeds are fine, the kernel with this update deep sleeps better than most that I've flashed in the past month. It's been nothing but good so far

For a device that already had bad radios for low signal areas, the reception issue is bad. It is not like going from great radios to good radios, but going from barely okay radios overall to worse. Everything is relative and the radio changes absolutely suck in that regard.

I"d say this thread is now dead since Samsung / Verizon have now pulled the OTA and will release a fixed version later, That usually means 1 day for Samsung to fix it, and 3 months for Verizon to test and approve the release.
In comparing the S3 to two other Verizon Motorola phones in my family, I find the S3 signal to be as good or better to the Motos when running the current stock software, (not the broken MD3 OTA) . SO I'd say its pretty good as Verizon goes. Interestingly, I find that the Verizon S3 is not nearly as good in signal as my wife's Sprint S3 , Surprising because VErizon and Sprint often share cell towers.

This is exactly the thing. After using MB3 update a whole week, giving it a chance....my phone would still WORK in areas with strong signal, but everywhere else it went from ok to UN-usable!
There is a clear issue here but if you are in areas with only great signal you may not notice as much but it's there.

What they should do is release here first. There are no better beta testers then XDA members and we could probably find every flaw within a day, and heck our devs can probably fix most of them for Samsung anyway.

Samsung usually releases a test release on KIES for their own stuff, but Verizon of course won;t let them do that for Verizon phones because Verizon has their own professional way of doing things....hahahaha

[Q] anybody else having 4g connection issues?

About 3 weeks ago after installing the update of liquidsmooth 4.4.4 i randomly started dropping to 3g service in places that i normally had full 4g available. It has slowly gotten worse to where if im not on wifi, than the phone is pretty much useless. i normally have full coverage everywhere. so i originally thought that maybe something had gotten messed up on the update, so i did a clean install of liquidsmooth 4.4, and blackbird kernal and same thing still occurred. also tried carbon rom and slimrom, and no luck. so for the fun of it, i went ahead and reflashed the phone back to stock from backups and rerooted it, updated the modems and reinstalled liquidsmooth w/ blackbird kernal, and same thing. i have went through all the mobile networks settings and tried everything and nothing seems to help, idk if that update screwed something up or if its an issue that others have been experiencing as well, or if im just screwed and my phone phone is dying.... any help is appreciated thanks

I'm currently running OmniToad, and ran CM 11M8 for a short while. On T-Mobile at least, with the custom ROMs it's normal to see H+ only when data is being transferred; it will drop back to 3G otherwise. When I ran the stock ROM on the Relay, it would always say "4G" regardless of whether it was in UMTS (3G) or HSPA+ mode. Apps like SignalCheck or CellMapper will tell you which mode it is really in.
On the other hand, if data transmission is only going through as 3G, it could be a phone issue or a tower issue. Is LTE available in your area, or are they just getting it set up? I know when T-Mobile was upgrading the Chicago area to provide LTE, there were a few glitches here and there.
It was stupid for T-Mobile to brand HSPA+ as "4G" but that's a different rant.

yea LTE has been in this area for quite a while now, i had it with my S4 and it worked perfectly, i never had a problem with the service on the relay either up untill a few weeks ago the internet speed and and data coverage was great, not quite as fast as the LTE on my S4 but it was still more than adequate, i used to use the hotspot and stream netflix on my laptop. now i can usually get a text to send but calls usually fail and if i try and use the internet its impossible. it almost seems like its doing the exact opposite of what it should be doing, as soon as i try and use anything (not while connected to wifi) than it drops coverage to 3g/edge/ or to nothing at all. Im leaning towards the hardware failing side, but i figured i might as well give it a shot and post it and see if maybe i wasnt alone. thank you for your reply.
small note of background on me: first time posting ever in this forum but have been using the tools and roms from it for a long time, so im not a complete noob, but i definitely still have a lot to learn.

Verizon Signal Issues - Help

I need some help here, weird Verizon signal issue. So I got my U11 on Thursday the 22nd of June. I tested out the stock rom, all working fine, signal working fine too. Then I unlocked the bootloader, put twrp on in system RO mode, put magisk on, then put viperU 1.0.0 on. Viper/magisk and everything was working perfectly, I still had signal, could make and receive calls, send and get texts, wifi was all good, everything was good until Friday afternoon. I think it had to do with me trying to install the ota 1.1.0 viperU, but my signal dropped, still had 4g but that was touch n go. I tried to reinstall the ota because as far as my settings said and knew, I was still on 1.0.0 and when it checked for updates it found 1.1.0 again. After that 4g would work for a moment at boot then die, and there was no signal for calls/texts, that has the signal bars full with a slash through them. I tried fresh installing viperU 1.0.0, no change. I tried every combo in the test/advanced settings, changing the preferred network mode and ims settings, turn the radio off and back on and it would see verizon and try to connect, sometimes seemingly getting signal and changing the signal bars and getting 4g, then losing both. The status msgs on the advanced settings page would go back and forth as far as registered on the network, so I went to verizon and tried to get a new sim, the new sim didn't change anything, BUT a weird thing that happened is when the vzw rep went to the back to get me a new sim and activate it my U11 got signal, both 4g and call/text and I even got a msg, then it died again a moment later. So next I tried completely restoring and relocked my bootloader and installed the 1.11.617.4 RUU for my OCNWHL using htc_fastboot which it did perfectly fine, but still no signal. The bootloader says relocked(L) and software status: modified. Shouldn't it say official again since I flashed the RUU? I have tried reseating the sim and rebooting multiple times too. Oh and one more thing I noticed, my WiFi is touch and go now too, it'll say connected but websites fail to load, apps fail to download, etc until I turn off and back on my phone WiFi. Any ideas guys/gals on how to get my phone connected again? I just want to be able to use my new U11! Thanks in advanced!

All I can say is a lot of people are having problems with Verizon, me being one of them. I've had the phone almost 2 weeks and still can't get it working. I've talked to HTC and Verizon so many times and they say it's being worked on.

same here. Spent a couple days with near constant contact with Verizon trying to figure out out. Got in touch with HTC and it seems it may be a firmware issue. I can verify with no doubt that it's not the sim though. I've put mine back in my old phone, it worked. I put my daughters in my new phone, it failed to work. I even got a new sim for mine, but no luck. Multiple ROMs, multiple RUUs, and multiple factory resets, and wipes. All we can do is waiter, and pester the hell out of HTC to get them to hurry up.

It's so stupid that they don't even do testing before putting it on the market.

If either Verizon or HTC would come up with a simple software update to enable CDMA and all LTE bands, that would solve everything. The problem seems to be that Neither is putting much priority on it.
BTW: Since the U11 works with Sprint, it has the CDMA and LTE bands built in. They're just not set up to fully work with Verizon yet.

Exact same problem.
My unit is going back for refund tomorrow. 4 hours of work trying to get it going and I'm done. HTC blames VZW, VZW says it's hardware. $650.00 paperweight. No thank you.
I'll reorder if this get straightened out. There are hundreds working just fine on VZW.
Seems to be just a few of these that wont stay connected.

I was starting to lean towards firmware today because of the wifi going in and out. Seems like to get an app to download from play I have to search it, start the download, turn off wifi, turn it back on and then it'll download, yet updates download just fine. Fandango app won't load movies or anything. Etc. So I'm wondering if it's the system or radio...

stock U11 no issues on VZW
I took my sim out of my VZW line to test it out on my U11. I did some speed tests before I took it out. I inserted the VZW sim into the U11 and it booted up with no issues. Received LTE and ran speed tests and they were similar to the other device. There was VoLTE available and it was stable but I didn't make any calls with it. So just sharing my experience with my stock, Unlocked U11. I put the Tmo sim back in but it's good to know it'll work. It seems like some are having issues from the get go and some are having issues after modifying?

That's what's so screwy about it. On mine, I get WiFi flawlessly, and I even get mobile data, in 4g even. I just can't talk, or text. Before that, I could text, but no data, and couldn't talk. It's got to do with the way it's using the radios being screwy. The hardware functions, I've had full connection before, it lasted about 2 hours, and sounded amazing even.

Short answer: Yes. I noticed mine stopped after installing a ROM on it, but it was not the first one (test driving to see which I liked on it best). Others have the issue even with it locked still. I think the ROM flashing was more a circumstance than the cause in cases like mine. I even RUU'd back to stock, did factory resets, and tried other SIMs. It also seems to be only Verizon, unless someone on another network wants to set me straight.

I remember an issue on Verizon and the M9 that after flashing a custom rom, you stood the chance of loosing VoLTE. It did not happen to everyone and did not happen all of the time. I flashed custom rom for months and then one day, boom, VoLTE gone. The only way to get it back was to get the phone replaced. RUU did not work to get it back. Sounds similar to what is going on now. So my question is has this problem affected anyone that has not unlocked the bootloader yet?
I just checked the M9 Verizon section and looks like they did find a fix without replacing the phone. But I think you need to be s-off. Interested if this could resolve any of these issues here.

I remember an issue on Verizon and the M9 that after flashing a custom rom, you stood the chance of loosing VoLTE. It did not happen to everyone and did not happen all of the time. I flashed custom rom for months and then one day, boom, VoLTE gone. The only way to get it back was to get the phone replaced. RUU did not work to get it back. Sounds similar to what is going on now. So my question is has this problem affected anyone that has not unlocked the bootloader yet?
I just checked the M9 Verizon section and looks like they did find a fix without replacing the phone. But I think you need to be s-off. Interested if this could resolve any of these issues here.

I will be trying this later today. Good ol' @dottat

If we get s-off we can probably safely flash roms without magisk n still have volte n even a more stable radio/system firmware, if dev's make it happen of course. Or am I wrong, I don't mind having magisk, I just want to be able to root n customize my phone with it still working as a phone n not a fancy calculator or wifi only device haha. I'm debating getting a replacement from HTC until the firmware stabilizes at least, then I'll mod some more. Cause mine was working perfectly fine until I tried to put viperu 1.1.0 Ota on it.

I just noticed that when I drag down and get the quick settings into view there's a note in the top left that says "the sim card is missing or not readable. Insert a sim card" and that doesn't go away even when the occasional notification that says "sim card inserted click here to finish setup" pops up.

Was fine for a couple days - now suddenly today only getting "roaming" service. Manually trying to connect to VZW fails and says my SIM isn't allowed access.

The full story is in the op of this thread, but it started about a day after I got the phone, started with only voice/text going out, then lte dropped too so now my phone is wifi only. R u on stock or have u unlocked ur bootloader?

Ah sorry, didnt notice you were OP. I have unlocked but was running stock OS with Magisk (no other mods, I just wanted root). Noticed that turning of VoLTE in phone settings killed connection, so I was able to toggle that off and on (+airplane mode in between) to usually resurrect connection. Now nothing is working. Going to do a full wipe now to see if it comes back.

No worries haha. My signal today is intermittent, I'll get bars but can't call because when I try 4g turns off. In the HTC test settings, when I have bars it sees Verizon network but not my phone number, where as when I don't have bars (bars with slash through them) it sees my number but not Verizon network. For u to see this menu type *#*#4636#*#* in the dialer. My VoLTE is activated in settings tho.

Factory wipe didn't help either. Doing RUU now. This is so ridiculous. Also I accidentally deleted my backup, oops. Le sigh. This thing will probably be going back. Sad. I was loving the phone.

Bruh - go in menu -> Phone Info -> Turn Off Radio
Select "LTE Only" Select "WCDMA/LTE"
Turn radio back on.
Fixed problem instantly!!! Thank you SO SO MUCH!
edit: MMS doesn't work, but SMS seems possibly ok? not sure.
edit 2: WCDMA/LTE is the magical answer. All seems working now.
