Hello everyone, im new here kept searching everywhere for solution for my problem without any success. In may 10 i bought SM-G955N KT module, it was working great with 2g / 3g / 4g / LTE / LTE+, i went out of usa for almost 3 month and when i came back my phone doesn't work well with tmobile, i can send msgs use lte internet but i cant do calls at some areas, some times i have full lte bar and when i try to make a call it goes to 0 signal bar, i called tmobile many times about the issue but no solution i found out that they did upgrades to their towers in the period i was out of usa from may to august, right now i cant use the phone as any normal person its been a month that i cant use the phone at my house and some areas, i can make calls sometimes if im at different tower locations. Question is, is there any solution for this problem since tmobile did those tower upgrades its screwed up everything..... should move out to att or verizon or what should i do. I really need help with this problem its been a month, any solution would be welcome if it requires root or not i dont care i just want to find a solution for this,
Thank you.
Have you tried resetting your network settings and/or getting a new sim card?
Its not the sim card i already changed it to a new one also i tried it on a iphone 7s plus and it works fine, my phone is bone stock no root no custom software alsi its the korean version when i looked around i found that tmobile did some network upgrades from may to aug and thats when my phone got screwed up, i was albe to play with the ims setting and i got the phone to recive calls but i cant make calls, does my phone screwed up because it has the korean csc and the stock firmware or whats going on here
I'm not quite sure I understand your experience. From what I am reading, you went to Korea, got the G955N (which I bought for both myself and my wife), and then came back to the states and can't get it to work with T-Mobile?
I tried to get mine to work with T-Mobile and have experimented extensively with different CSCs and ROMs.
I eventually went over to AT&T
I've also had a rather extensive experience of how to get 4GLTE working here in the states with AT&T.
Feel free to reply here or DM me if you wish.

Hello thanks for your input, actually i bought the phone in the box brand new from amazon, it came here on may 10 i used it for 7 days 4G LTE 3G works great then i had to go out of country for 3 month i came back at the end of august to find that tmobile did a huge tower upgrades in my area, since i came back i wasnt able to do calls and receive calls, i was only able to text and use LTE internet but not calls, i went to different towers area and i actually was able to make calls but not in every area because some times my signal bar goes down to 0 or even 1 signal and i cant make calls still but my other friends who owns iphones or usa version of android works fine except me. Yesterday i edited the IMS setting im still on stock fw and i enabled every single feature there and i was able to receive calls in my area but still i cant do calls, i wanted to make sure if im gonna follow the steps here in this guide i will be able to use TMOBILE CSC with the korean stock firmware and get the features of tmobile as VOLTE and WIFI CALLING etc with the right CSC for sure and without tripping knox
Thank you
Hi, I did some extensive searching and was not able to find a solution for this.
I've got the SM-G955N, and ran into the same issues as other users in this thread with T-Mobile, has anyone found a workaround to unlock the LTE bands necessary to make the SM-G955N work with T-Mobile?
I didnt find solution yet too, i dont know what to do i gave up i tried everything on the official software no root.

I had a phone with the Korean CSC as well, N phone as well. I left the CSC alone and it worked with T-Mobile and ATT here in the US just fine, last fall.
I later changed the CSC to XXA, and still works well. Just tested it this week with T-Mobile, and it's working. I have to say, that locally, T-Mobile has much poorer spot area service than ATT. Kinda puzzling, but that is the way it is.
My phone is rooted, so it make things a bit more handy to mess about and return to my previous setups.

Recently purchased the Xperia Z5 (E6653) and I am having some serious issues with calls on T-Mobile USA.
Calls don't dial out (or it takes multiple tries) and calls won't come in when the phone is connected to 4g (LTE); they go straight to Voicemail. I missed about 12 phone calls yesterday - just getting voicemail after vaoicemail till I realized something was wrong on my side. If I toggle off the LTE it drops to Edge (no HSPA+) and calls come in fast and outgoing calls are made with no problem.
I tried to reset the phone, then repair the software with the Sony Companion app. Still same issue. Looked online for the APN settings. Tried various ones. Re-downloaded the Internet/MMS via the phone itself. Same issue. Tried my wife's sim and it was still doing the same. I have a spare 5s and it worked fine both incoming and outgoing calls. So, it doesn't seem like its the sim card.
I have Rev 2 of this phone so I am not sure if that is anything to be concerned about. Am I missing something...any help on this would be appreciated.
Thanks.
Maybe flash a T-mobile firmware with flashtool?
Or Flash 209 firmware meant for usa?
Or wait for someone here that use this phone on T-mobile.
Are you on band 12 LTE by chance
No, it said band 2 with LTE Discovery. I am on the verge of sending it back. Swap it for another one. Let's see.
From what I have gathered/read - it should really be straight forward. Pop in sim, load Internet settings, and it should work on T-Mobile. The APN settings are correct.
Doesn't makes sense for it to completely not work on 4g and go to 2G (Edge) while skipping 3g. I'm wondering if the baseband might just be wonky. I just see this as causing more problems down the road which I don't want from a $520 device.
Any advice is welcome because I am ordering the same phone again. Lemons are always possible.
Could it be possible because I live a relatively rural area (East TN) and the phone does not support AWS? Since it doesn't support T-Mobile VoLTE and doesn't have AWS it is defaulting to 2G? Is this an issue in all areas or just rural? Apparently the E6683 variant doesn't have this problem as it supports AWS.
Check this http://www.xperiablog.net/2015/10/07/usa-buyers-guide-sony-xperia-z5/
That means ur phone should work fine with T-mobile,maybe go and get a replacement from where you bought it.
I spent over 2 hours last nite with att reps trying to enable numbersync to work between the s3 and s8 phones.. the s8 phone is an unlocked phone (not bought through att), only to find out today via another rep that the phone must be bought via ATT or truly att branded.. which i find a bit absurd, as i think others have succeeded..
Is this really the case.. anyone know or have this same experience?
Specifically this error would appear after going through the get started via the watch then on the phone (after creating a seperate accessid):
Oh darn! We can't enable device syncing on this phone. Want to find out more? Call us at 800.331.0500 so we can help.
(MSSITWINREL12)
If this turns out to really be an unlocked phone issue (which is a bit ridiculous), i think i read that it might be possible to take my sim card out of that phone and put in another phone that is att branded, enable number sync then put the card back in my s8 and go from there
Thanks
The phone does not have to be AT&T branded, I have a T-Mobile Note 4 and until the last update numbersync worked. Updated my S# over the weekend after avoiding it for as long as possible, and now numbersync is no longer an option on my S3.

Thanks for the reply.. your saying you had an unlocked tmobile phone on att and it was working till a recent tizen update then?
The rep further told me to take the phone to the best buy samsung experience store and have it flashed with the att firmware to get around this issue.. maybe not needed then? (which i assume means a wipe and possibly lose my unlock)
I had the same problem with my Gear S3 and my Axon 7. Worked on for a solid hour with an ATT rep in store and another hour on phone with someone else. Finally it was determined that it wouldn't work on an unlocked phone. Haven't tried the sim swap with an ATT branded device yet, but if I do, I'll let you know if it works.

Spoke to an att rep again today who called me.. basically in my case the 950U1 s8 phone.. because its this model it wont work with numbersync they say.. they also contradicted the previous reps suggestion of taking the phone to the samsung experience place and having the att firmware flashed on it (or doing it at home).. saying it wont help.. that they need HD voice provisioned and it wont let them provision it (the phone wont).. they said swapping the sim card to a real att phone only may help for a short period, till the system does a sweep, sees a non att phone and reverts it (same with just adding the imei to the database).. There is also a good chance the recent update to either the s3 or the samsung s8 caused numbersync to do a detection for unlocked phones and not allow this (they indicated).
They said i could still try doing the firmware flash but it probably wouldnt work (i dug around online trying to find out which flash it would be and i didnt get too far, short of going to the store to do it at best buy samsung experience)
Really sucks, as the alternative, if i were that desperate to enable this feature (i dont think i am willing to go this far) would be to sell the old phones and get new att branded ones.. end up costing me the price of a new watch in the mix just to do that

When I first bought the watch it was for the numbersync feature. My first problem was even though the Samsung rep and the bestbuy rep said that it would work with my Note3, it did not. took several calls and many hours of trying to figure out the HD Voice (VOlte) provisioning. Bought a TMobile Note 4, rooted and rom'ed this worked to setup numbersync. the only problem was it would occasionally turn off numbersync, this occurred about once a month. Then if failed completely said that this line is not accceptabl;e for numbersync. this was after about six months. Discovered that it appeared to be age of firmware related, I was on a TM firmware that was several updates out of date. When I odin flashed the latest firmware numbersync worked again until the recent update to 3.0.0.1 on the gear firmware. Now I have the line not acceptable for numbersync again. I'm going to try to update firmware again to see if that works. If not I will probably look to change carriers to TM. will cost the price of a new watch, but will get me out of AT&Ts locked boot loader.
BTW, setting up numbersync on a different phone and switching back will not work, Tried several times and as soon as you turn on the phone that is not HD Voice capable with your SIM card in it the system sees it and turns off numbersync almost instantly. went throught that trying to get my Note 3 to work.
In all my experience the Samsung and AT&T reps were not a good resource. Numbersync does not appear to be a very popular feature and they do not know much about it.

My main motivation for it has been that.. someone correct me if this isnt accurate.. if your phone dies or is off.. when you dial someone from the watch or text them it will still show the cell phone phone number, not the watch phone number as it does now if bluetooth isnt on.
I'm in the process of gathering the files i need to do the att firmware flash and hopefully hd voice works then (as others say it has).

Yes, that is the whole point of numbersync. The watch uses the phones number not it's own.
Tried updating to the latest firmware and a ROM based on it. No luck still get a rather comical response "Oh darn! We can't enable device syncing on this phone. " worked until the tisen update.
There also seems to be confusion on numbersync with the att reps.. one person told me the watches dont need their own numbers.. that numbersync is all we need (but how would the watch make a call if the phone is off).. another said yes they need external numbers for number sync or solo
edit: i see your last post.. so the latest reps are correct then.... so they assigned us numbers and $10 access fees each with activation fees for no reason basically.. ugh
The watch has to have it's own number, that is it's address on the network. Without it numbersync would have no way to send calls to it. Same as with the LTE enabled iPads they could not make a call, but had to have an address on the cellular network.
Just a quick note...i too spent 3 hours in an AT&T store trying to get numbersync to work..., finally returned the S3 Frontier cancelled the number in it and left frustrated...i now have a GS8 unlocked on AT&T through my work...that is synced to a Verizon Gear S3 Classic lte and i simply use call forwarding with YouMail. If i do not answer my phone after 3 rings it gets sent to my watch and if I still do not answer then Youmail picks it up..If I call out or text with the watch separately then I just let my customers know that I have 2 numbers 1 for my cell and one for their watch. I just don't think AT&T is ready for the Numbnersync technology yet and they just don't care enough to train their own people on it, sad as it is a good promise...

I meant phone number.. are you saying phone number? After the rep said i didnt need a phone number for each watch, she credited me back the cost of the two lines and said just to contact them that they would enable the numbersync once i had the phones ready.. I'm assuming number means imei, which they still have in the system.
Yes each watch has to have it's own phone number. I believe this is another case of AT&T rep not understanding number sync.
I managed to firmware update so that i have the att bloatware (didnt even need reset, all software was kept).. i confirmed HD voice is working but WiFi calling throws an error to contact ATT.. hd voice was the key for numbersync.. however.. despite this.. and 2 hours on the chat line with ATT.. i still get an error when you do the s3's get started numsync and it opens the page on the phone.. the oops, device sync cant work with your phone (which went from a 950U1 to a 950U btw, which is good as well).. They escalated to another backend team, but i highly doubt they will get it working.. most likely they'll still complain that my phone (was) an unlocked phone, despite adding the att firmware to it.

Update here.. i managed to get everything working by going with a new sim card.. wifi calling works now.. and i was able to complete numbersync setup.. the only remaining issue i have is that my callerid seems to be blocked on the receiving end.

With the Firmware did you have to go through the full process where you changed the CSC and flashed the ATT firmware? Currently I am running a Sprint phone that is unlocked an running the US Unlocked firmware. Even running the ATT firmware they still were not able to get HD Voice or WiFi calling working for me.

The full steps, or mostly full.. are here in this thread..
The short of it was that i only ran regular odin at first.. just did HOME_CSC (using the verizon firmware which covers all carriers).. then rebooted the phone and did all the check boxes and the regular CSC.. after rebooting nothing was wiped and att bloatware was there... at this point hd voice was working.. wifi calling wasnt.. so i went to the store, got a new sim card today, then wifi calling was working.. numbersync took the code on the phone without error.. however.. now i'm realizing it isnt really working.. when i turned the phone off, and texted, it showed my s3 phone number.. and my callerid is still botched.. i think att botched something in this whole process.. so yet another call to them needed.

Thanks. It sounds like the latest firmware they did seems to fix some of the issues from bringing a non-ATT phone over but does not resolve everything. It looks like I won't be able to do this though. ATT and the ebay seller are unable to clear the ICCID on my watch, I have to sadly do a return now.
Kinda unrelated, yet ATT was horrible even for normal Sammy phone/watch. After dumping ATT service/hardware for various reasons a few moths back... Sammy watch/phone from Verizon hardware/service works flawlessly. Am carrier neutral, but one works reliably, one didn't.
BTW, Sammy pay via watch hiccuped via ATT at times, yet works flawless via Verizon.

well 5 chat people later they finally fixed the unknown callerid issue.. apparently there is an internal back end feature for numbersync regarding it set to active and on.. both toggles were on.. the rep removed the "on" and now my callerid shows my number when calling from my phone (and from the watch when watch is in solo mode too).. everything works! :laugh:
So having recently upgraded from an unlocked T-Mobile device running on ATT, I was expecting that I would have better connectivity since the T-Mobile device I had didn't have support for a lot of bands. However I haven't had data work at all since setting up this phone.
Full disclosure, I'm on blackwireless. But it's an ATT mvno so I should still get their network.
But I'm getting zilch.
Talk and text are just fine, just no data.
I'm also not fully used to the interface on this phone cause my old one had actual "bars" in the icon and would also say LTE or 4g. Maybe both, is it sad that I've already forgotten just three days into owning a op7?
Firstly, anyone else an blackwireless, or ATT having issues with data?
Haven't yet called blackwireless because their support is 100% outsourced.
Had same with T-Mobile, it wanted me to sign in...and that page said this plan has no internet. So I called support, they ran a diagnosis but before it could finish ! Near the lte disappeared and it worked

Have you looked at your APN settings?
Sometimes it just doesn't select anything or it's empty!
You're right. That was the exact problem. I ended up calling the support line and it was a much better experience than I remember. And there were several apn to choose from. I just had to choose a different one according to their documentation.

I know. What I meant was my old phone was T-Mobile. My op7 I bought direct from OnePlus.com
I'd like to get Wifi calling, Visual Voicemail, and 4g on an unlocked A515F.
As of now the phone reports itself as this:
Baseband A51FXXU3BTH5
Service provider (stuff) TPA TPA TPA TPA
Network AT&T
Moble network state disconnected
Service in service
IMS not registered
Mobile voice LTE
Mobile data LTE
VoLTE seems to be on? I thought this doesn't work on unlocked phones.
Being new to this the providers are all over the map on all kinds of stuff regarding unlocked phones. (AT&T rant I'm sure many of you have been here Grrrr.)
Network mode auto is LTE/3G/2G, there is no 4G option (as I believe in my research is how it is with unlocked phones)
So, I suppose the question is, if I follow the steps outlined in this thread:
https://forum.xda-developers.com/galaxy-a51/how-to/guide-how-to-change-csc-a51-t4129243
and flash the AT&T firmware, will I get 4G, Visual voicemail, and WiFi calling? As well as whatever the heck ATT disables for unlocked devices.
Will this require another trip to the store and a 4G SIM put in there?
New to this, but I have tried to research this as much as I could. Thanks for all the info.
Steve
Forum?
Have I put this in the wrong sub forum? Should it be in the firmware flashing forum?
First don't need to flash anything unless you want to waste your time with bloatware.
What you have to look into for your service desires, is do you have wifi in your service plan? If yes, did you activate it on the A51 you are using? (Also make sure your sim card is sim 1)
Also you don't have to use any provider's visual voicemail to get it for your phone. I've used YouMail for about 2 decades.
As far as lte & 4G. My phone is from same csc TPA TPA/TPA. I've seen both 4G & 4G LTE on my service. So your question about that was a little vague. But U.S. providers (at&t or tmo) won't tell you 90% of the time that you have to get 4G LTE sim card & pay for a 4G LTE service plan on order to get it.
Thanks for the reply.
It's sim 1. IMS not registered my be the issue, ill call ATT tomorrow.
I've been able to get visual voicemail back by installing the APK. The play store says it is not compatible with my device, APK was fine. I will check and try what you suggested.
Yeah, it might get a few chuckles here but i've had a S5 for years, and replaced it 3 times with ebay s5's. Love it. Initally i just popped my old iphone 4 sim in there and used it forever. I never had wifi calling and when i attempted to enable it it said the sim was the problem.
Imagine my surprise after going to the store and getting the proper sim i see the 4g icon appear and wifi calling, etc. All these were ATT firmware phones, on power the logo pops up, bloatware, etc on the S5's. Miss it already. What am i going to do with all these batteries and chargers?
This has been a different thing. Being in the States, not traveling overseas (at this time i believe no one will have us anyway) and this unlocked phone. As far as bloatware goes, its still kinda there in one way or another. Clicking on a link within chrome forces samsung internet every once in a while. Yeah, there is no real extra stuff on the device as it is. Its just weird.
Getting a sim for this at the store took a little more time then I thought it would. The employee was checking out the phone for a little longer then just handing me a sim.
I've changed the APN, possibly to the incorrect settings, to get 4g and wifi calling bacK. But that seemed to knock out any mobile data. Granted I may have entered the wrong settings. I'll look for others.
What's really confusing is the lack of these things. Is this phone cabible of 4g in the hardware? Wifi calling seems to be a forced ATT unlocked thing.
Sorry, long winded. This article states that when I am seeing the 3g lte it is really 4g.
Egads, link without 10 posts wont let happen. It's the B&H photo article regarding unlocked phones.
The wireless calling is not happening. Is this inherent to unlocked phones on ATT? VoLTE is on as far as the settings tell me. I'll poke around some more.
Many thanks
Steve
4g was on the S5 so i would assume it was part of the plan. Switching to the nano sim A51 should not knock that out.
I've read so many posts here, as i know my questions are pretty basic compared to other discussions, so thanks again.
If you'd like to discuss the numerology hidden in octal permissions let me know
If there was a screenshot of the mobile networks
Data roaming off
VoLTE SIM1 On
LTE/3G/2G (auto connect) checked
3G/2G (auto connect)
3G only
2G only
Yeah, I just bricked it ish. Tried the A51U-1 At&T firmware USA. I'm downloading the Italian Samsung firmware to get it back I hope. "Only official binaries are allowed".
The phone was in emergency mode and showing the PIT error with the A51U1 firmware.
The Italian firmware set uploaded fine. Now only it only shows a white circle with the little lightning bolt inside if connected to a usb cable. Computer wont recognize it. Resetting it vol down and power/bixby key turns the display off for a sec but it comes right back to the same thing. This is bricked huh. Any ideas?
Holy cow I held the vol down buxby bixby button down as I removed the usb cable I am getting the factory data reset screen. Maybe there is hope.
Yeah same thing again. If anyone has this issue you can at least get back to factory reset by holding the buttons and quickly yanking the USB cable out when the charging logo disappears.
-edit again
Recovery mode vol down + power. When it blanks keep the power button down and push vol up.
I wonder what to try in the choices.
Wipe cache?
Reboot to bootloader?
Im looking at the last log there is a whole lot going on. At about 80% of it is shows a ******FILE SYSTEM MODIFIED****, then it looks like its setting the octal permissions on a bunch of stuff, then it looks like it cant find /etc/firmware/calliope_sram.bin and from a bunch of other places in the filesystem.
After about 87% it looks like it is basically describing how it is displaying the recovery mode screen.
Displayed is samsung/a51nsxx/a5111/RP1A.200720.012/A51FXXU4EUC8
The phone came as an A51F. Was trying to flash to A51U1(ATT).
-Edit again.
I have hope for this but I am aware I am a flippin second from bricking the device. Any input is highly appreciated.

I will attempt this if I can find the download screen,

looks like is TPA for Panama, Downloading firmware through Samsung firmware downloader. But I would like the USA ATT firmware so I can have 4g and wifi calling. OMG Im gonna brick this thing.
Reboot computer and phone reboots into Cyrillic I find this rather funny at this point. But it is the phone setup screen and routine.
edit-- Hilarious. Didn't even install the Panama TPA firmware unless Samsung Firmware Downloader did it by itself while I was taking a nap. Cyrillic boot? looks like it is on the network at least I think can talk to someone been a lonely couple of days.
edit again== This is a linux computer that can make phone calls. WTF is the deal here. Really? All this stuff? I'm exploring all the custom ROMs and whatnot here in the forums. All I wanted was 4G and wifi calling. That is what my S5 did and I loved it. The S5. Flippin old phone but a fun one. Thousands of dollars to ATT over the years and they wont turn this phone to 4g on for me?
Thanks for everyone that has put effort into this that is amazing I really cant thank you enough.
edit yet again. Maybe flashing the firmware I have to wait for a couple of hours for it to fire up? I am assuming everything I am doing is wrong.
Can do... https://forum.xda-developers.com/t/guide-how-to-change-csc-on-a51.4129243/

Network AT&T
Mobile network state Disconnected

Also android 11 I may have been 10 before?
No bloatware but the Yandex stuff.
No ATT logo on startup.
Again thanks for all your work and knowledge on this stuff, I'll poke around some more and see what firmware is actually on there. It says SM-A515F/DS.
Oh! A515FXXU4EUC8.
SER/SER,SER/TPA
Again thanks - ramblings form a newbie.
SER CSC, well that explains Yandex.

First don't need to flash anything unless you want to waste your time with bloatware.
What you have to look into for your service desires, is do you have wifi in your service plan? If yes, did you activate it on the A51 you are using? (Also make sure your sim card is sim 1)
Also you don't have to use any provider's visual voicemail to get it for your phone. I've used YouMail for about 2 decades.
As far as lte & 4G. My phone is from same csc TPA TPA/TPA. I've seen both 4G & 4G LTE on my service. So your question about that was a little vague. But U.S. providers (at&t or tmo) won't tell you 90% of the time that you have to get 4G LTE sim card & pay for a 4G LTE service plan on order to get it.

Force encrypt,
Magisk,

Extract PIT from the working firmware and pit tab? Agh.
Consider myself lucky running SER TPA firmware?
Am I about to trip Knox?
Welp, getting the 3G going away feb 2022 messages from ATT even though it does display the little 4G icon at times. Called Att they say they can see the imei. They say sending a new phone. Not an a51 who knows. Most likely some thing that up the account to $100 a month.
Be warned the you will loose everything is real on firmware flashing but weird. Thought i copied the entire filesysyem but things dropped out
.
This is an old model phone so i understand and my first shot at flashing it. Probably try again as i think i did not flash the u1 correctly. Still can talk, text, whatever. Frustrating, old phone, who cares.
Ah they sent me a S10e for free no complaints. Ill try the att a51 firmware again nothing to loose at this point see what happens and follow the guides.
Hi all,
I have been stay up two days to looking for my solutions and would you guys at least let me know if this is impossible or possible?
1. Bought Global Unlocked AT&T phone from my friend. When he sold it to me, I made sure it is unlocked and move to any carriers.
2. I check IMEI numbers and everything from Verizon (I called them) they confirmed this phone is compatible in their netowrk and will work.
3. I switch my iphone 11 max pro sim card (verison) and put it to Samsung Z flip 3 5g.
4. Everything works find but, I saw AT&T logo when I start the phone. I also some of AT&T setting's everywhere. I did factory format and showing the same thing.
5. I called verzion and they said, because I use 4g sim to 5g phone and asked me to visit their direct retailer to get free 5g sim card and I did.
6. HOWEVER, after change even sim, it shows still AT&T logo and AT&T related menu in the settings and everywhere. Also, I did not even have wifi calling feaatures.
6. After that I have been search and study two days but, still couldnt' figure out what's going on. What I found is I need ask my current carrier to push OTA. (that's the one of other people suggested and I did chat with verizon and they said, they will get back to me after senior engineer to check if they can do it.
7. They also make sure my phone is registered their networks and works fine.
It is really bothering me to see some of AT&T settings still turn on and also shwoing in this phone.
Probably this phone is global unlocked phones provided from AT&T from the beginning.
While i am searching and reading the articles, lots of people told me to gave up because i am even on Verizon, they said I have to depends on AT&T's OTA updates and etc....
it is my fault to bought it from my friend even tho I belived that because it worked, I thoguht that everyhthing would be fine......
What should I have to do? Just stay with it and sell it when z flip 4 is come out? Do I really didn't have any change to correct this issue?
I was fan of iphone and i swiched to android first in my life and everything went wrong. I want to fix and stay on Samsung. Would you guys can at least let me know there's no way or there's way to correct this so that at least I can ignore everthing and stop trying to find answer all day wrong........
Thank you and sorry for long question... you guys are my last hope.
Thank you in advance.
Respectfully,
