I'm wondering if it could be something to do with the combination bootloader/firmware/GSM modem/LTE modem versions?
I'm still on the old bootloader, using 4.4.2 (Danvdh's) ROM and on MH1 LTE modem.
No matter what GSM modem I've tried, I can barely have a conversation longer than a minute before the call gets cut off.
After researching, I've seen this is quite a common problem on the EE network, but I'm curious to know if there is any particular bootloader/firmware/gsm/lte combination that works better than others.
My question goes out to those of you in the UK on the EE network, and how your voice calls and data reliability has been.
I would be grateful to know the following:
1. Location in the UK
2. Bootloader version
3. ROM+ROM type
4. Firmware version
5. GSM Modem
6. LTE version
7. Frequency of call drop-outs
8. Reliability of data connectivity
For me, this is as follows:
3. Danvdh, GE ROM
5. NE5 (but I've tried more or less every new modem since MGA)
7. Pretty much very call. Sometimes the call drops after only a few seconds. Occasionally the call may last a minute or two before dropping.
8. Extremely unreliable particularly in borderline LTE areas that need to switch between 3G and 4G modes.
Perhaps point 8. may improve if I upgrade bootloader+LTE modem to a 4.4.2 version? This is one of the main reasons for starting this thread.
More worrying though is the extreme unreliability of voice calls for me.
Any input will be very much appreciated.
