It occurs nearly every 8 minutes when I'm using an android or native app in LTE mode. no problem while in standby and no problem in 2G, 3G or Wifi. I use Jio 4G in sim slot 2. please help me identify what is happening. i don't know the use of the terminal, hence need someone to tell me the exact steps. occurring since 3 days. before that, everything was normal except the alien-dalvik crashes that i've mentioned earlier here - https://together.jolla.com/question/154086/alien-dalvik-restarts-when-mobile-data-connection-crashes-in-lte-mode-no-problem-in-2g-or-3g/

Update 22-07-17 After many testing It is Concluded that Unexpected reboots are Only Experienced when: 1.) Both Sim Slots have SIM cards AND 2.) One of them is 4G lte supported

It seems their is bug in dual Sim handling which crashes os (makes it boot again) when one of the sim is 4G lte supported.

Network mode remains upon prefer 4G as here?link text

i am facing the same issue my friend. use jio internet and phone reboots in a while. i only use native apps and i get a random reboot with no time frame . i guess sailfish isn't 4g friendly after all. i deleted my question which was almost same. thanx rajuaa00.

I have no rational explanation for this but try to change used slot, move SIM card(s) to another slot(s). It will not give you neither VOLTE nor better LTE support but may make reboots less severe, more seldom - if you will have luck, or simply not. My guess is Jolla is waiting for the LTE & VOLTE standard to be more established globally-internationally as now it differs from operator to operator and jio's is one of less friendly for current Sailfish implementation (or vice versa so to say). Jio is cheap, the cheapest, but that makes side effects like not investing in their infrastructure and software unless absolutely needed. It also implies also from fact that e.g. VOLTE requires experimental finding of values of some hundreds (100s) of parameters which are to be set in existing operator's infrastructure. That is process consuming manpower, and also requires to complete individual software for every particular mobile model, what is not easy in Jolla's situation. So we all are waiting for VOLTE and better LTE. However note in some countries LTE works without problems.

i have thoroughly tested this, if u use another jio sim you get the same reboots. no reboots on other sims whatsoever. jio never worked in sim slot 1 before Iijoki but still u cannot use internet on jio in sim slot 1
