- The first part (RF calibration) means they adjusted the radio to improve reception and transmission(rx/tx), so your call/network/wifi reception will be better; the battery level adjustment implies they altered the voltage to improve battery life. In both cases it's more likely they replaced faulty parts with fully functioning ones. Good to see you finally got your issue solved Mick
- It seems like what they did is install the OS from factory state and give u a new battery and maybe re clocked the CPU. Unfortunately they won't give you the proper information on what they did nor will u able to find it. There are some apps which tell u what system and software it uses but that's about it
- All that I can tell you is RF stands for Radio Frequency. Apparently your cellular radio was tuned a bit off from whatever frequency(ies) your carrier uses. I wonder how they calibrate this.
Their statement "Adjusted battery level to optimize power usage" makes no sense to me. It's almost an oxymoron! But then, when signal level or reception of signal is poor, firmware detects this and gives the hardware an extra kick of battery juice. So maybe that's what they adjusted?
I'm really just guessing about RF calibration and battery adjustment. Hopefully somebody more knowledgeable will shed better light, especially regarding your questions about processor speed
I also would like to know what they did with 'improving radio frequency'. Got the same problem as you, and would like to check if it's possible to manually fix the radio/frequency-problem, cause the guys from the repairshop didn't fix anything for me..
Otherwise: is there an app that notifies me when network connection is lost ?
I found this one : (updated url) https://play.google.com/store/apps/d...networkmonitor
that works well..i now see immediately when my phone loses network connection.
However, now i still have to manually reset it by turning on/off airplane mode. Is there a way / app that does these steps automatically ?
So notifies when network dorps, and then refreshes it..
That would be one way to solve the problem i think..
