MTP acting strange

Have anybody tried MTP file transfer in Linux? I am having some problem with copying the pictures in Kubuntu. After selecting the files it seems like there is some copying problem.

In Windows 10 it works without problem.

Also, my older phone LG L90 with cyanogenmod 13 worked fine.

WiFi acting up on my ALE-L21

For some reason the wifi on my phone is acting strangely, it just started doing so a few days ago but before that it was all fine. Basically what is happening is that my wifi will be really slow to the point of not connecting to websites (Connection timed out etc.) however the wifi starts to work if I turn it off and then back on, but then stops. I really don't want to be doing that every 5 seconds. It used to be fine and then suddenly it started being weird. So basically my phone is quite useless now since I use my phone for everything (I log into my google account with my phone, I need to use the steam app on my phone and other important stuff). The wifi on all my other devices is fine like usual. Bluetooth also says that the bluetooth address is unavailable but I don't use bluetooth so it doesn't affect me but I think it's also to do with my problem.

Currently using Sokkoban's Deodexed ROM.

What I've tried doing:
Removed PurePerformancesX.
Cleared Cache.
Reflashed the ROM.
Flashed to the Official Lollipop update.
Flashed to the Official Marshmallow update.
Rebooted my router.
Reset my router.

Anything else to do?

Note 4 acting odd

Well first things first, I was running a stock Tom lollipop 5.0.1 have a custom twrp 2.8.2 I believe, still have it been having it for a while tried 3.0.2 no difference so I switched back anyways I tried flashing stock rom all of them from T-Mobile starting with the original KitKat rom, I tried the stock 5.1.1 T-Mobile Canadian rom and it worked but it rebooted about every 3 minutes , so after trying many Roms also deleted everything off the phone first through teamwin recovery, I finally got a semi stable Tom which is resurrection remix I have 5.7.0 but had 5.6.9 anyways now it works almost perfect reboots maybe 3 times a day and thats with heavy use, by the way the annoying thing is when it attempts to reboot it gets stuck in the Samsung logo, I remove the battery and reinsert it and it boots like a champ, also if reboot trough os same thing happens, sometimes it won't turn on or take a charge unless I leaves the battery removed for a few minutes about 5. It's gets very annoying have tried so many things nothing seems to fix it and I have 3 batteries so if can't be that and original charger could it be a bad power supply ? I will upload pics in a sec one battery is worse than the other two holds no charge,. Stock rom would get stuck in the T-Mobile logo.
