Only for SHV-E210S (SK telecom) which is a Korean version of Galaxy S3 LTE.
Tested on firmware version LG3 (Android 4.0.4).
"RadioInfo" doesn't work on JB(Android 4.1). It works on ICS(Android 4.0) only.

I am using Samsung Galaxy S3(SHV-210s) phone (which are made for Korea) in Bangladesh. However, I was tired of frequent call drops. But after installing this app and selecting the network as 'GSM all', the call drops have been reduced to zero. Great app !!
Try to update software but my phone keep prompting unable to update software. Use SKT USIM. Please advise me which setting should I adjust to solve this problem. Thanks.
Looks promising for the specific model. Can anyone or the developers please tell me, is this app also available for SHV-E300S ? I understand that if I use settings meant for another version the phone may brick. Thanks in advance.

Really
Changed my network settings to wcdma all since lte is not yet that good here, so far it went good hopefully it stays like that, good work dev
i search to here application. o
I can't use this app-,-
what about on e-120L? will this one work to e-120L?
Can you build for Kitkat version of S3 Korean..?
Use full
Worked well in the beginning but with every new android release features of this app stopped working until only the 1st option would work. This would have been an great app for shv-e210s owners if the developer had of kept the app up to date with android and usable for the life of the phone. Updates please!?!
