[Q] Screen freezes

I've had my LG G2 for a couple of months now but a couple of weeks ago my screen started freezing and becoming unresponsive. It doesn't happen every time I use it, just now and again. When it freezes I can turn the screen off and then back on and everything works OK. Has anyone else encountered this problem? I live in Thailand and see where we are supposed to be getting our KitKat update in a couple of weeks and I am waiting to install that and see if it will fix the problem.

Galaxy S4 I9506 Post Repair Wifi Terrible Range Problems

Hi guys,
I haven't found anything like this issue before in a thread, so sorry if I missed it.
My S4 has been going through these weird episodes lately with its wifi. Every couple of days after wifi is working, out of the blue the wifi range just craps itself to the point where I have to be with a meter of the wifi source to get signal and use it normally. The signal only picks up at a max range of 2 meters. A couple of days later it goes away and then wifi works fine for a few days and the cycle repeats itself.
2 months ago the phone went to a repair shop for a new screen because it was dropped and destroyed. The wifi issue started a month after the repair completely randomly. I'm just wondering whether or not this is a coincidence or a loose part because the repair shop believes that I have to get the wifi chip replaced. Could it be something less or are they right? I have ruled out software issues by completely wiping and reinstalling my custom ROM and no one using it has reported similar issues.
Thanks guys, your input is greatly appreciated!

Random reebots during phone calls or incoming calls

Dear friends, I am using the Note 3 (N9005) from more than 3 years and I love it.
My issue is a bit weird and it started long time ago, when I installed my first custom rom (miui). I have changed 3 different roms and recently replaced also the battery with a new one but it did not fix it.
The issue is that the phone sometimes reboots itself during phone calls (or when phone call is coming, before I answer). These reboots are just random and except this issue... everything is just working fine.
My provider is Czech T-Mobile, is this can be related to CSC choice? Any thoughts?
No one can help?
Test sensors .
Flash stock rom via Odin and test .
