Is it okay to disable these apps?

[prodigy]

Hello everybody. I disabled these apps on my Z phone. I want to know if it is okay to disable them or not? And if not . Can anybody tell which apps should I enable? Which programs can I diable safely without affecting my phone's performance?

PS. I sometimes receive a message saying ( unfortunately google play services has stopped). Not only this, I also get this message especially after installing many new apps on the phone and when I enter the SETTINGS- then APPS- a message pops up ( unfortunately settings has stopped) . I press OK then goes back to home screen. Anybody can help? Thanks.

It takes some time for pictures to be approved by forum moderators, can you put those pictures to dropbox or google drive and put the links here?

Hello Quester. I'll upload the pictures again. Sorry for the first pictures, they were useless.

Hello Quester. I've already disabled these apps.And I want if they affect any of my phone's functions or not. Do U have any idea about them and are there any of them which needed to the phone functions? Thank U again.

It will work, but you're losing some of the "smart" functinality of your smart phone. If you still have a problem with errors that appears when you install apps or open settings, I'd suggest that you do a PC Companion phone repair, this will do a clean installation of the latest firmware and will also wipe your internal memory. You're already considering upgrading to Lollipop and I advised you on a different post to do it by PC Companion phone repair.

Open PC companion -> Support zone -> Phone/tablet software update -> Repair my phone/tablet (blue link style). Follow the steps given, do not connect your phone until prompted to press volume down while plugging USB cable.
