Default Network Signal Low since 4.3

Hello,

I have a Samsung Galaxy s3 and ever since going to 4.3 my signal strength for mobile is weak, very weak.
I have re booted phone, taken battery out, tried different modems but all with no luck.
Has anyone else had this issue and successfully fixed it?

Cheers

Got the same issue, as I flashed the new Alliance Rom on my S3 LTE. Most time I had just one of five network points.

So I did another Full Wipe, and used the Boeffla Kernel with stock modem.
Got slight better results, but there are always lil interferences while talking. Probably its the bad network by german T-Mobile.

Regards

I have the australian optus version and signal where I live is really crappy on 4.1.1 I upgraded to 4.3 the newest one from hong kong (the one my rom is based off) and now I have found that the modem and ril driver in that version is giving me stronger 3g and 4g signal

DONATE TO ME
Hey everyone I am back developing again haha Noticed this myself with 4.3 so I have looked into it and noticed something very different with 4.3GSM RIL class files. They are are all reverted to the standard GSM ril type files, where as on all previous generations have used QMI based RIL.

I have created a patch that I am about to test and if I have any luck I will upload it here for you guys to try out for your selves. It should work for other countries as well so long as you have noticed a difference in the RIL types between 4.3 and 4.2 or earlier? If not then I would suggest leave things as they are and flash a new modem.

I am on Optus and I am comparing the first 4.3 release to a stock Optus Android XXALI5-OPS, does anyone know what the version number is called from the OTA update for Optus?

help find a cure for Narcolepsy
donations to this cause do not come directly to me, they are
anonymous but please tell me so I can give you thanks
