Lost sound during calls, process isn't responding...

Dear XDA community,

Recently my LG G4 H818 (dual sim) started causing troubles after 8 monthes of use. Everything started a week ago, when during the call I couldn't hear the other person. The other person could hear me well. It didn't matter if I was calling or I was receiving a call. It didn't depend of which sim I was using, call sounds from both sims were silent. After reboot this issue was resolved. Temporarily... After couple days everything started again and again reboot helped.

Yesterday, after regular reboot due to this issue, my phone showed an error - "Process isn't responding. Do you want to close it?". This is where nightmare started. Everything froze or started lagging badly, I couldn't unlock the phone, I couldn't launch any app, even notification drawer was not coming down, the phone was useless. I could receive calls, but I couldn't pickup (phone freezes instantly). When I tried to launch an app, it would say "This app isn't responding. Do you want to close it?" before freezing for couple minutes. It was happening to every single app (Phone, Contacts, Shazam, Whatsapp, etc.). I barely managed to save my data to pc using usb cable and decided to hard reset (erase all, format data, etc.).

After hard reset, during the first launch everything seemed ok, no lags, no errors... BUT this morning I received a call, picked it up and sound was missing again. I did the reboot and now I'm back again to freezing, huge lagging, errors, and phone is useless.

Everything is stock, latest Androd 6.0 is installed. Not rooted, bootloader is locked - I have not done any changes to the firmware at all. I did drop it once on the hard floor (only once) after a month of purchase, but until last week everything was working ok. I must mention that battery wasn't lasting long enough, but it might be due to my heavy use (9GAG, Chrome, Corporate email app, gaming sometimes) - charging 3-4 times in 2 days.

Has anybody faced same issue? Can anybody help me? Couldn't find any results on google and on forum here. Please help.

P.S. rooting and installing a different ROM is not an option, since dual sim LG's have limited available custom ROMs. Also, I use a corporate email app that cannot be installed on rooted phones (it is really annoying).

Thanks in advance!
