Hello,
I am experiencing a strange issue with mobile data, the most similar thread I could find about my issue is here:
http://forum.xda-developers.com/gala...ivity-t1149716
I am using Samsung J1 SM-J100ML, Android 4.4.4, Kernel 3.19.17-366995, Mar 26 2015, bought new as unlocked rooted
The phone was purchased new and everything worked great for a few months. Recently I took a short trip overseas to Australia and bought an Optus SIM card and installed their android app from Google play (this was the only change I can think of that could have caused my issue). Upon returning home and using my normal SIM, I found my phone is now constantly switching between HSPA and HSPA+, sometimes many times per minute. This interferes with web browsing or using chat apps, as the connections seems it must reset, which takes a few seconds each time it switches. This issue is making is incredibly frustrating to use the mobile data now. I ruled out issues with the SIM card, no mobile data issues on my other Samsung devices in the same location.
From my searches on this forum, I want to try to access the setting "CHANGE HSPA REVISION" so I can lock my device to a frequency to prevent switching, or disable Fast Dormancy.
I tried codes such as *#301279# and *#*#9900#*#, but they are not working. Uninstalled Optus app and threw away their SIM card already. I also tried starting the phone in Safe mode, but I still noticed the mobile data issue.
I can access the ServiceMode using *#0011#. I tried many combinations of selecting "Back" and entering "Q" then "0" or "00", or "Q0", "Q00", "Q0000", etc.. but nothing works.
I called Samsung for help, but they never heard of ServiceMode, and recommended a Factory reset.
My options as I see it:
1. Factory reset (long process to backup all data, reset, restore... I want to avoid). I suspect my issue is software related and will fix the issue, but its not guaranteed.
2. Find the correct "Key Input" code so I can use the ServiceMode and change settings that may help.
3. Buy a new phone.
Any ideas? Any one know the correct Key Input code to get farther in ServiceMode for this device? Thanks.
