Stalker freezing and out of synch

Hello guys, I am having issues with freezing and out of synchronization of some channels, now this is happening with Android 4.4.4 KitKat, when I tried with Android 5.1 same channels with out of synchronization work perfectly no problems at all, I did some searching found about advance settings but no luck, last test was using another add-on and disbaled the Stalker Client, with this test all channels work perfectly but lost the EPG, is there a way to fix this? Both TV Boxes are set with Kodi Jarvis 16.1, the only TV box with the problem is the Android 4.4.4 KitKat. If this problem can’t be fix can I upgrade the TV Box from 4.4.4 to 5.1?
Thanks in advance IPTVKid
My setup is
30 Megas internet speed
Both TV Boxes are connected via Ethernet not WiFi
Both Boxes have Kodi 16.1 Jarvis

P.S.
I also tried the Kodi Media Player SCMP and Stalker Client same problem.
