Upgrade GT I9300 to GT I9305 - Upgrading, Modifying and Unlocking

Hello there, so.. friend brought me a GT I9300 it had broken motherboard. I had one at home but it was LTE version of S3, so i decided that i will move frame and other stuff from.. So problem is with network, every time i i get a call it does ring , but i can't hear anything also they can't hear me... same goes for when i call someone... Signal is weak it changes like every 10sec from full to 0.
Regards Mat.

[Q] Cell phone booster for TELUS Samsung Galaxy S2 X?

I was just out camping where I had very faint cell phone reception (ie: I would get 1 bar and then it would go out). I was looking at getting a cell phone signal booster for my Samsung Galaxy S2 X but I am confused on which one to get. I was looking at the Wilson cell phone booster but most of them say "Except Nextel/iDEN and 4G", so does that mean it won't work with my Samsung Galaxy S2 X? Thanks

No it will work but it only boosts 3g/EDGE and voice connections so you will be able to make a call and send txt messages but not alot of data usage.

Phantom Voicemails? Missed calls due to phone not ringing?

I currently have the SGS2 (epic touch 4g) on sprint and have had the issue tooooooo many times were i get phantom voicemails and some times my phone wont rign at all or it wont start to ring till the 4th ring then by then most people hang up . I use my phone heavily for work and a miss call can be loss of $ revenue.. These issues happen even when i have full bars of reception. A friend of mine has the SGS3 also on sprint and is having the same issue ..
I want to get the note 2 for many reasons but just cannot have this issue . Dont know if this is happening on all samsung phones but it didnt happen on my epic 4g.. or if this is a Carrier issue (sprint).
is anyone having these issue's with the note 2?
I had this happen to me tonight. I had 4 bars of service and my phone said I had a new voice mail. I checked it and it was from 2 seconds ago. No ring no missed call. I think it has something to do with the time in between cell tower pings. I wish I knew how to Be shorten this time. On another phone I had it was set to 7 seconds and some calls would go to voice mail befire thw phone even knew I had a call. I shortened it to like 4 seconds and never had the problem again. I think it was something to do with saving battery life with the slower ping times. I wish I knew the code to change mine on my At&t Note II.

[Q] Best radio for Bell GSM Galaxy Nexus (Montreal,QC)

Hey guys,
I'm curious as to which radio has worked best for you guys with Bell Canada. I'm situated in Montreal, QC. (I don't know if that detail will help at all)
I currently have Baseband version i9250XXLJ1 installed by default. I get fairly decent download speeds (roughly 3mb down), although I get a lot of dropped calls, dead zones and area's with very poor reception compared to my mates.
Thanks in advance for any help.

Same thing

I've been having the same issue as well. I had my original Gnex that I got with bell. it broke recently and I got a new replacement Galaxy nexus....Same dropping call issue.
the problem I have is I'll be on a call for like....5 mins and all of a sudden the person on the other end cuts out, then I try to hang up the call but it's almost like the phone freezes for 15 or 20 seconds and then returns to normal, at which point I call the person back. It's really annoying and since I can't make the phone emulate the problem, Bell won't replace it for that reason. If you've found a fix, please let me know!

[Q] Swapping motherboard on s3

Okay so im gonna be getting a At&t Galaxy s3 and i wanna swap my tmobile motherboard with it because my tmobile s3 has a crack screen and will i be able to swap them with no problems and will i be able to get the same signal and data ? or are the antennas different ?
please reply
Can you please update what happened with your attempt
I somehow don't think you can. The T-Mo Device is missing the LTE Antenna whereas the ATT model does have one.
More importantly, why do you wish to swap ? You didn't mention any issues with the ATT version. Are there any ?

L520 horrible signal

I have 1bar or red xall of the time. I have found that this only occurs when switched to 4g LTE. If I switch to 3g only I have great signal. Im currently in NJ. If I reboot whole in lte I get signal for a bit then back to none. Been working on this issue with sprint. The reps never heardof thisissue and At first the rep insisted I swap my phone out but, I refused because I believe I have pin pointed the issue to LTE and would rather be part of the solution. A ticket had been opened with Samsung. Let me know if you have the same issueand what you have found. For now just rousing strong on 3g. I'll keep everyone posted.

Hi,
I am not sure if your post refers to the Galaxy S4 mini (as I see in the subject you write "L520"): please confirm if we are talking about the same device otherwhise I should create a new tread.
Anyhow, here is my issue:
I live in Italy and have Vodafone as phone carrier. I recently got S4 mini phone. Before I have been using a Nokia XpressMusing 5530 phone.
I have always been having full signal with 5 out of 5 bar. Since I moved my SIM from Nokia into Galaxy S4 mini things got worst. I have most of the time barely 1/2 of the signal I had with Nokia, still in the same place and same carrier. Where I had 5/5 now I have 1 or 2 out of 4.
I reported this issue, which I greatly dislike to Samsung Exclusive support team and was told that I am forbid from comparing brands and even models as each individual smartphone or phone behaves differently. I replied that when a person spends €400 for a phone, it is implied that phone signal must be perfect! Sometimes, when it changes from Data to Wi-Fi the phone signal disappear and it reappears un within 5-7 sec displaying a circle with a bar across (meaning no signal).
Is this phone supposed to behave so bad? What to do?
I am still undecided whether to just sell my phone and get something better, like HTC One.
Thank you,
Spiro
Buon Giorno Spiro. Yes I Am referring to the galaxy s4 mini in the USA. The phone should have great signal. Im not sure how to Fix this either.
