Hello All,
I am hoping that someone can help me out.
I purchased 6 Samsung Galaxy S3 unlocked phones. I put SIM chips in each, all from the same provider and all with the same service plan. 3 of the phones everything is working great including fast Internet. The other 3 phones have extremely slow Internet. I did a bit of research and noticed that the phones that are slow display EDGE in Mobile network type. The phones that are fast display HSDPA:9 . Could this difference be the cause of the data speed problem? Can anything be done to fix it?
My apologizes if this is being posted in the wrong forum.
Thanks

In your way, EDGE means slow, HSDPA fast, HSDPA offers speeds up to 21mbps (if your carrier supports it) and EDGE up to 0.5 mbps or so.
Now, if your 3 other phones don't connect to HSDPA (3G) then it's disabled in settings or signal is low or the chip is messed up.
So by checking if everything is good go to settings, under first tab (connections) go to More networks > Mobile networks and make sure that under network mode WCDMA/GSM is checked, notice that WCDMA is HSDPA.
If still not getting faster speeds try to check if WCDMA only option works, if not, eh, bad chip.

Thanks for the reply.
I activated the WCDMA/GSM. As soon as I did the icon status(?)displayed on the top of the phone turned to a circle with a line through it. About 3 minutes later the status changed to an E with bars next to it. The Status/Mobile network type still says EDGE.
When I try to connect to a site it is slow. Does this mean the device is still getting the 2G signal? Could all 3 phones have a bad chip?
Thanks.
that is true

Do all of the phones have the same baseband? Check in settings, about.
Just to make sure the modem is the same.
I just check 2 of the phones (they are all not with me now)
The baseband of one of the good (fast) ones is: I747UCDMG2
and on one of the slow data phones is: I747MVLUEMK5
What does this mean, that they are not the same?

Both are i747 version which is not international version, maybe Korean or something like that, try using only WCDMA this is constant 3G, and see if it works, if not, flash the latest software from sam mobile via Odin, but watch out you download for i747, not i9300 etc. There are many S3 variants.
I tried using only WCDMA with no success.
Do you have instructions of how to locate and flash the latest software? Also I know the phone is currently unlocked would this change that?
Thanks so much.

If it is unlocked, it shouldn't change that.
And note if changing software doesn't help then the chip might be damaged.
For software, go to www.sammobile.com and register, then go to browse firmware and select android/galaxy s3 bla bla.. until you get to country, there select your country, or go to top and select 'top 10 latest' and choose one that is different from yours.
You can know of it is different by the baseband name letters for etc 'XXUGNG3'.
Then download the software you want (it may take a while) and download Odin v3.09 (just type that in google you'll fond ot) and Samsung USB Drivers (also found on google easily).
Install usb drivers, reboot, open Odin, extract downloaded firmware, go to odin and select AP and then navigate to extracted zip and select you software.
Then put your phone in download mode: hold vol down+power+home and then vol up for continue when you see the picture, connect your phone and flash.
Also, please, about that, read here on xda and see tutorials on youtube, this has been answered multiple time and.i am one of rare users that will thoroughly help in answered questions.
I followed the instructions and flashed the phone. It did not help.
Any other ideas? One of the phones we got was brand new! I can't imagine there is a faulty chip in 3 out of 6 phones?
I am frustrated.

Are they unlocked? Of they are try another carrier, or try somewhere where the signal is at it's best reception.
If these simple methods don't work just get it analyzed in the service center, i doubt it can be software problem because you tried with another rom, also, when you'll try maybe changing carrier or going around town to see if it works, and it doesn't, then it is hardware problem, unfortunately.
Thank for all your help.
Nothing seemed to work.
I did try another carrier and it did not work.
I just can't imagine that 3 out of 6 phones have the same problem and 1 of them is new.
Could it be that the 3/4 G only works in the USA and not in foreign countries?

Hi all,
First time poster, long time follower!!
I'm hoping someone can help me here because i have a real headache with my galaxy s2.
When i got it at Christmas everything was perfect. But two weeks later i suddenly lost my 3g. Phone works fine on 2g (except for the slow speed), but i contacted my carrier 3Ireland and they said everything is fine on their end. My APN is perfect, i've tried toggling airplane mode, entering codes, data package checks. You name it and i've tried it.
When i force my phone to select 3g it looses all signal and i have to restart my phone and quickly go back into settings to choose 2g or i will loose signal again.
This is the following on my phone.
Android version 2.3.5
Baseband version I9100XXKI4
Kernel Version [email protected] #2
Build number GINGERBREAD.XWKI8
I've being reading about modem/radios lately, is that just the baseband? Could that be my problem. I'm a noob at this kinda thing.I just want my 3g to come back.
All help is greatly appreciated. Look forward to hearing from you all.
Thanks.

It would be interesting to know your SGS2 is white version as well as mine.
I have to say that I have another SGS2 but old black version which is perfectly functional on the same 3 network. After playing a very long times with both phones settings, I have a feeling that the core of the problem lies in the "APN type" setting. Changing it's content affects how it connects to network. I have no deep understanding of what is happening behind the scene while changing this option, but there is a possibility that the portion of file system responsible for it somehow been damaged.
It would be great if the developers could tell us if this part of the Android file system is changed while flashing different firmware/radio, or it is persistent?

Dial *#*#4636#*#*, go to phone information and see the settings for the radio. It should be at the bottom. Google the settings for the GSM, WCDMA. Mine is currently 'GSM auto PRL'. 'WCDMA Preferred'is also a better option for 3G network.

Thank you. I fiddled with GSM, WCDMA settings as you said, but no luck.
What is even more interesting is if the network mode is set to "WCDMA only", then I'm not even able to register on 3 network. After an attempt to manually connect to 3 via "Network Operators" menu, it says "Unable to connect. Try later".
Also after connecting via WCDMA, and then reverting back to GSM, the GSM dies as well. The only solution is to restart the phone.
If it is a software bug, then I do not understand why this problem did not go away after flashing different Rom with radio.

Same problem
Same problem for me in Spain...
WTF happens with this Galaxy S2.First USB voltage problem and now no 3G/HSPA connection.
Any solution, plz??
Samsung: never again
guys....carriers can't sell a device that is advertised as a 3g capable phone. Call them and spit "misleading advertising" mixing "give me a phone that I can actually use" words. You could also add "Release me from my contract, I'm moving to other 3g WORKING carrier".
They'll just freak out.

T-Mobile USA?
If yes, you're probably in a market that they have not yet re-farmed the 1900mhz frequency for HSPA+ yet. The i9100 doesn't get 1700mhz, and the majority of T-Mobile USA's network uses the AWS band, which requires both 1700 and 2100mhz to work for 3g/"4g".
Hello Guys,
I am so desperate and frustrated, hope you can help me!
I dropped my phone from 2 stairways height.
It was working so i didnt care, but when I came home I noticed that I had no reception!
So as I have bought the phone from Germany Amazon.com and using it in Turkey, I had no warranty (even if it said I have!!) I decided to open my SGS2 (I9100) and see if anything was loose. I lifted the pins that touched the middle housing and now I have reception for phone calls all the time thanks God!
But I have no 3G at all, what happens is that is some times shows G in the status bar but never with a + sign near it. I saw + sign only once or twice in the last couple of months.
I called my operator which is Turkcell and they said that my contract is on 3G so no chance on that side. The wierd think is that my phone works with no other SIM card than mine which is 5 years old!
Can anybody help in order to solve my problem? Is there a diagnoses tool that will help me test my SGS2 in order to find the errors?
Thanks for reading guys, I'd really appreciate some help.
Hmm I'd check my APN settings first, make sure they didn't randomly change for some reason. If that failed, I'd factory reset. If that failed I'd flash a new firmware+kernel+modem, and check my APN settings again.
If that failed I'd open it up again, disconenct and clean the antenna wire, reattach and hope for the best.
If that failed I'd suss out what is the most appropriate looking part/area of parts to replace, then replace it with either that specific part, or a pre-assembled part with the surrounding parts attached.
If that didn't work I'd list it on ebay as clearly stating the phone is damaged, outlining the problem and sell it "for parts only". Lots of people pay good money for damaged smartphones. Just make sure any sensitive data/pictures etc have been securely removed before selling it.
The problem with reception was fixed with lifting the pins that touched the middle housing but, stand by :
I think I never had 3G since I bought that phone from Germany.
I feel so stupid!
I read through more and more and I found that article:
androidforums.com/samsung-galaxy-s/258859-how-enable-850mhz-3g-network-frequency-your-samsung-i9000-galaxy-s.html
It mentioned about the modem frequencies so gave it a try.
dialed the number * # * # 1 9 7 3 2 8 6 4 0 # * # * as stated and bingo!
My modem doesnt list GSM 2100 which is the deault frequency for 3G in Turkey!
But the article doesnt mention how I can ADD GSM 2100 from the menu that dialing that number took me.
Any help with this is appreciated!
First, that article is for am i9000, which is the S1. But that's largely irrelevant because the service menu code still works.
Second, this phone doesn't get GSM 2100. Never has. It gets WCDMA/UMTS 2100. GSM is for voice and 2g, WCDMA is for 3g/HSPA. Looks like you went to the wrong option. (GSM, instead of WCDMA, like the article said.)
Third, you CAN'T add frequencies, on that menu or otherwise.
Thanks.
So why is that my phone connects with only Edge?
Can this be a hardware problem where everything else works?
Maybe these setting are wrong? Or maybe it has a SIM lock? but it works with Turkcell
Is there any manual so that I can these settings_

You said above you don't think you ever had 3g. Maybe your carrier uses 3g frequencies this phone simply doesn't receive.
For example, this phone well never get a 3g signal on T-mobile USA's network, because the phone doesn't receive 1700 UMTS/WCDMA. This is one of two required bands on AWS... Which is the band T-mobile USA uses for 3g and "4g". If your carrier uses AWS for 3g, it won't work on their network either.

No this is not possible. Turkcell is using 2100 Hz.
I have bought 3 phones from amazon.de site. The other 2 phones are working.
I have to get my settings set properly, to make sure its a faulty product, so that I can return it.
There are menu options like HSPA revision, GCF, bank selection, service domain, acquisiton order etc..
Where can I find what they have to be?

In that case, just go back to that service menu, debug screen - phone control - network control - band selection. Make sure this is selected to automatic. You can make sure all available bands for this phone are selected on in combi bands. If they're all selected on, then it sounds like it could be a hardware issue.
EDIT to add: OR it could be a modem issue. Maybe try flashing different modems?

Ok, just a disclaimer (I am well-aware of my n00b status here)... I spent quite a few hours already on this site and on the Android forums, and on Google searching for answers to this... Not to mention time at the AT&T store and chatting w/some other phone reps (including Samsung tech support and AT&T tech support)... And while I've made some progress, I still can't get any definitive answers here.
So... that being said, first (and big 'sigh' I'm sure to many) is that I'm using a South Korea Note - the SHV-E160S. I know this is the I717 forums, but before I get flamed and booted, let me explain...
Well, I am on AT&T. No problems with calls or texting (minus the annoying 80-character limit, but anyways)... However, I have a BIG problem with the LTE. I'm on the LTE data plan, however, I cannot access any data network other than GPRS. Yes, my pings take about 533ms. My download speeds are about 53kb/s. This sucks, quite a lot. Esp when compared to my fiance's Note, which side-by-side gets about 13mb/s on the LTE network.
So... Did some research, and got the run-around... Less all the crap I heard from AT&T reps... It seems that the antenna for my Note is set to LTE850/LTE1800, and the actual AT&T SGH-I717's antenna is set to LTE700/LTE1700/2100. My sources for this come from PDAdb.net (I'd hyperlink, but my post count is not high enough to do that, yet).
So... Here come the questions. First... Is the antenna frequency tuning something built-into the hardware, or is it something that can be tuned via software?
-If it's in the hardware, would it be possible to buy an AT&T-spec LTE antenna? Which antenna gets replaced (from what I understand, there are two, and I can't find a legit source that tells me which is which), and where could I buy such a thing?
-If it's in the software, what would I have to do to re-tune the antenna? My phone is rooted with the latest Gingerbread Tegrak kernel.
Lastly... Though there is a difference between the LTE antennas... I still cannot access any network other than GPRS. I should at least be able to access EDGE, UMTS, HSDPA, HSUPA and HSPA+ as well, but I can't.
If ALL else fails, I guess I could get a portable tethering device with a contract... But that'd be oh-so-annoying to have to carry around all the time, and I'd like to avoid that option as much as possible. I'm paying $30/mo for LTE service on my phone already!
Anyways... Any thoughts or advice would be very appreciated, and my apologies if anything here is out-of-place. Thanks in advance!
U have the international note. Doesn't have late chip in it. But ur note has better CPU then the att note. The international note CPU is not comparable with att lte chipset that's y Samsung use 2different CPU. Yes u should be able to get 3g. Reset your apn. And search around. To find the code to reset your apn. I forgot. Its something like *2260*
I had an international first, had to rest everything to get data. But after few days. I return it cos I prefer to have lte speed more then CPU speed. And I found out the u can just over clock att note to 1.85 instead of stock 1.5. So now I am very happy with my att note.

Hmm I'm not sure if this method works with the International Note but it's worth a try. You need to get into ServiceMode. On your phone dialer keypad type *#2263# and choose 2 WCDMA Band Preference and select (6) WCDMA all.
Reply with your findings.

Thanks for the tip, but all I get is an error: "Connection problem or invalid MMI code."

Maybe the issue is your kernal and/or radio? Isn't the Tegrak kernal Korean? Most likely your radio is also. That is probably your issue. The way I see it you have 3 choices: Live with it, Sell it and buy an I717 variant, Take the risk and at least flash the ATT Gingerbread radio.

Do all your entries match these? Write down your current ones before changing or take screen shots. You must use the menu key and save changes. Also make sure that is the APN checked after rebooting.

he doesn't have the international note(n7000) he has the South Korea Note - the SHV-E160S (he says it in OP), which it has the same processor as ours but some minor diferences in other things.
To the OP, why do you have a korean Note when from your avatar you're in the US?, I'm sure there's your problem, that note is set to use bands in korea and not in US, so the data is going to be crap, and for you to attempt to swap out the antenna is risking braking the phone because you run a chance after swapping it, not working and not having a working phone anymore.

I matched the APN settings of my fiancee's LTE Note first, and that did not work... It's pretty much exactly what you have posted. However, there are a couple things of note (bad pun, sorry). I do not have a 'APN enable/disable' or 'Bearer' field... However, everything else is set the same.

I have a Korean Note because I was living in Korea for a while, and I just got back to the US last week.
As in my OP, I found that the LTE bands are different; however, I can't even get on any other data networks other than GPRS. I've tried some APNs for HSPA+, and the results are the same.
Swapping the antennas shouldn't be THAT big of a deal if I had to... I'm pretty mechanically inclined. Obviously, I need to know if it would provide the intended results or not first.

Sent from my CM9 Note.
Hi,
I am having a problem with the network. I am currently using Idea mobile network and when I use WCDMA only option, I do not get any signals and also, when I am trying to use an aircel sim, I do not get any signals at all... is there any problem with the device?.. when I search for networks manually, I am able to see only airtel and idea in the list of networks... is amaze not compatible with vodafone or aircel or the various networks available....
When I try to use Data connection also, it is only connecting in 2g mode and not 3g... plz help.

Amaze is compatible with frequencies:
GSM:
850, 900, 1800, 1900 MHz
UMTS:
850, 1700/2100, 1900, 2100 MHz
Data:
HSDPA+ (4G) 42.2 Mbit/s, UMTS, EDGE
Have you had ANY phone work on the idea network properly? Same with the airtel?
For starters, switch from WCDMA only to Auto or GSM/WCDMA.

Yes, my other mobile which is Xperia Pro (MK16i) works fine with all the networks here in India...but i do not understand why Amaze is not working on 3g network while I am able to use 2g service (both data and calls) on the same network...

How about ask your local service person for the correct settings, or hopefully someone on this board who lives in your area can post theirs.
Is there an OTA specific to your phone?
While not the case with you currently, it may be important if you travel--there are some areas where certain carriers don't have that coverage:

some help needed
Plz friends can anyone help me with this... the aircel operating frequencies for 2g and 3g are 1800 and 2100 (my assumption)... the device is not at all working with an aircel connection (not even on 2g)... I am currently using idea network which is working fine with 2g but not 3g... when I try to search for available networks manually also, I am able to see 2G networks for idea, airtel, vodafone, and bsnl (aircel and some others again missing) and no networks at all when in wcdma only mode... when I switch to wcdma only, the idea network also vanishes completely....
I am not able to figure out what to do with this...
There are many Indians in amaze forum and former members, reach out to them and see if any one of them used your carrier, and see if they had the same issues or not

Aircel uses 900 and in some places possibly 1800. Do you have a data plan? Have you spoken with a support person with any one of your carriers--they're used to things like this and getting in the proper settings. I would strongly recommend that.
Check the Settings->About Phone to find out which version of android you have, and if you are running a custom ROM or not.
Do all of that first--make sure you have a data plan, speak with a support person, find out a little about your phone.
If you are stock check with your support person if there is an upgrade for you, also.
If you are NOT stock, you might want to go back to the Stock GB or ICS (remember to update the radio also) so your phone will be basic and stable, to be sure it will work at all with data. Once you've determined if it will work with data, then you can try one of the custom ROMs if you like, but NOT JellyBean or KitKat, as they are all problematic.

And as ravike14 said, "There are many Indians in amaze forum and former members, reach out to them and see if any one of them used your carrier, and see if they had the same issues or not."
I have a data plan activated...I have not done any change in software...the current version is 4.0.3..and aircel network is not at all working on my device..that y using Idea network (that too working only in 2g mode)...I cannot have support on the device as I purchased it online from someone else...and it is not a device which is for India... it is a T-mobile device..Do you this change of ROM will resolve this or will it still remain the same... can there be a problem with the antenna (but 2g network is working fine)....

I think it should still work. The tech should be able to give you settings regardless of the device origin--you're still paying for a plan, and some support should come with that.
Nevertheless, check this to make sure you have the right settings.
You "may" also have to call T-mobile and ask for unlock code for your phone--they will ask you for the IMEI.
I don't know if necessary, but have read something to that effect--that in using the Amaze 4G in another country, you need to have the phone unlocked. I'm sure someone else on the boards here will let us know.
The back cover houses the antenna, and yes, it could be the antenna, but unless you have another back cover to test it with, it will be best for you to check the settings first, and then see if it needs to be unlocked.
Then come back here with what you've learned--it'll help me learn too.
The ad said that the phone is unlocked... I purchased it from Ebay and I have a prepaid connection with the provider.. it is "pay as you go plan" so I guess they wont provide much help as I have seen customer care people putting their hands up many times saying it is a problem with the device and they cannot help...that's y I was trying to get some help here on the forum as someone else could also have faced the same issue and can help me with their experience...

Besides the firmware update, there has been a separate radio update.
I think these are the most recent updates:
Software number is 2.14.531.30 710RD
Baseband version is 1.15.550L.08DC_30.80.550L16D
It's possible that your phone will work with them.
Does anyone else agree?

You may be able to just put the official OTA on your exernal SD card and flash through recovery--not quite sure yet.
I gotta see some of the settings info, so for starters go into your settings->about phone, screenshot the page that appears and also scroll down to any new pages, and post screenshots here.
How to screenshot:
http://forum.xda-developers.com/showthread.php?t=1885386
After that, reboot the phone into recovery following these instructions, and screenshot the recovery screen and post it here also:
Power the phone off and wait about 10 seconds after the screen goes black to be sure it's off->hold Volume Down button, while doing so press the Power button, and release both buttons.
The phone will boot to bootloader, should say hboot up top, and have a little list below it.
If you can't screenshot it via the previous method, note if at the top of the page is says Locked or Unlocked, and if it says "S-Off" or "S-On", and note the version of hboot so you can post the info here.
Use the power down button to highlight the list item "Recovery", and then press and release the Power button to enter the recovery. After recovery loads, note if it returns to a screen just like the hboot screen, or if says in it "TWRP", "CWM", or "4EXT" or any such other thing, and screenshot that or get the info and post that here also.
Now that you've learned what sort of state the phone's in, you can reboot from whichever screen you're on, and have your phone back to normal.
Once you're back with your phone booted, you'll find a screenshots folder in gallery most likely, else you'll have to search the phone with a file manager app or google to find it, but check the gallery first.
After that we'll look for the proper update and update method for you.
Hopefully by then someone else will come along and say something like "All he needs to do is download this "Official OTA" [link included] and put it on the SD card and flash it via hboot"--hopefully, 'cause I may be making this more complicated than it needs to be.
Here, let me repeat that, "Hopefully by then someone else will come along and say something like "All he needs to do is download this "Official OTA" [link included] and put it on the SD card and flash it via hboot"--hopefully, 'cause I may be making this more complicated than it needs to be."
In bootloader, it is showing as:
Unlocked

HBOOT-1.93.0003
OpenADSP-v02.6.0.226.00.0202
IN RECOVERY: Team Win Recovery Project v2.3.3.0
I have also added screenshots as attachments for the about phone setting menus.

You did a good job with that--thanks. Hey, you're in good shape--everything is new enough.
You need to Super CID your phone, and then flash a rom for one of your local (in India) carriers.
Super CID instructions:
http://unlimited.io/juopunutbear.htm
ROM for carriers:
Sorry I can't provide the link--I'm having a helluva tough time searching.
Maybe by the time you've Super Cid'ed your phone, someone else will tell us where to find a proper ICS RUU for India.
Thank you
Thank you for taking out time for helping me...can any other rom (other than the T-mobile) working... and I dont know what is RUU..lol.. I am pretty new to these terms.:laugh:

In order to use the phone in your country you need to have one of your carrier's firmware on the phone so it is compatible.
You can't put their firmware on your phone until after you've performed "Super CID". After performing that, other carrier's firmware can be flashed to the phone.
RUU restores the phone to factory condition. Let's not concern ourselves with that just yet--follow the instructions to Super CID.
Hi, I am new to Sony family and bought used III which mightve been a Mistake.
I never see the signal having all bars full. It also reports values around 100dbm.
I have not been making calls really but I can see the reception is worse than with my old Xiaomi 9, same for 4g. Sometimes it drops and only restart fixes it.
Running dualsim, different carriers. Did network config restarts etc.
Lets assume it is sw problem. Could it be bad non-eu stock rom? How do I check?
I might immediatelly go with custom rom, maybe on android 12 just to see if it works better. Any suggestions? I just dont think factory reset or flashing stock is gonna fix it easily and I am open to experiments as long as the system and mainly signal reception is stable because next stop is trashbin really. The phone is overall great, I just did not expect phones having such problems nowadays.
I've seen the same, especially if I go underground for a few minutes - the phone can't reconnect unless I restart it or switch on and off the airplane mode.
But apart from that I have a pretty stable connection, no matter what the bars show.
My uneducated guess is power savings affect the signal strenght.
Never had problems during calls, no matter if driving or stationary

As A current Metro by T-mobile sales rep, and self proclaimed cell phone guru, some carriers require a phone to be registered on your account for it to fully work, even if the phone on paper has all the supported bands of said carrier. so this could be the problem, and if it's a software problem you can simply reinstall the correct firmware for your region and device and see if that fixes the issue, you could also try a different region but same device model number...

I have not really tested it much in such environment like underground. The signal mostly stays ok, not full at all but the connection works tho. I had only like 2-3 restarts/week due to connection reporting only EDGE available (still I couldnt browse anything) and both sim signals showed a problem (exlamation mark), I think it could have been caused by worse reception conditions and it eventually stopped working at all.

I dont see registration being a requirement here in EU. These are prepaid simcards, no binding to a device, no contract and such.
I dont know if its software problem. After little bit of Googling I came to a conclusion that Sony does indeed have problem with signal reception no matter what is the cause. To me it seems it could be SW related. Question is if flashing stock rom is the way to go or maybe using a custom rom as daily driver?

In the states Metro by T-Mobile is a prepaid company that uses T-Mobile's network, but they specifically require your current device to be on your account to make sure they can give you the correct info on why your phone isn't working correctly. And some times to send the correct configuration file to your device. But in your specific case i would say go the firmware route and see if that fixes it before calling the carrier to see if there's a config file or something similar they need to send.

Thanks for the explanation. I chose the FW route, testing AlphaDroid as of now. So far so good. Reception already looks better so I will stick to this rom for now and see how it performs.

Just a tip, you might wanna force 4G even on custom ROMs, I am running same config as you double sim and diff carriers but i get better result by forcing LTE Only on my main data SIM.

I have a quick update for you regarding my devices connectivity problems
I reflashed the latest global firmware, this overrides the modem 5g configs that you find on all of the 5g enabling guides.
immediately my reception AND my phone switching between 3G, 4g 4g+ etc was better. Im not saying im magically getting full bars, but its improved substantially on top of switching between networks when travelling etc is instantly now. Instead of me having to enable flight mode to reset my network every time.
i will try flash a custom rom and see if the reception stays fine
only had problems after trying to enable 5g and follow the guides.

Cool, thanks for the info. What is the version of that global fw?
I had only one network disconnect on AlphaDroid but it managed to fix itself within minutes. Still the display seems bit irresponsive to touches at times, baterry drain is not the best and also call quality does not seem to be the best. So I am considering switching to global or maybe different custom. Ofc it could be just my device.

You should start using 120Hz if it feels slow (go into QS settings and get the refresh rate toggle from there), also enable High polling rate from Settings > Display for better responsiveness, also if you're rooted/using Shizuku you should try https://github.com/kyujin-cho/pixel-volte-patch/releases it may unlock some SIM options that may improve your call quality.

Honestly, I don’t have a single practical use case for my phone where i need 5g enabled, so it’s really not a deal breaker for me to not have that enabled. 4g+ is still pretty quick especially for my use case. If you want volte & vowifi I recommend magisk + zygisk so you can use banking apps. Works well for me and call quality is fantastic
edit: I think I should note i did a full clean flash, flashing all and wiping all data on the phone. It’s been a few days and signal noticeably better.
edit 2: spelling (damn autocorrect)
