My phone keeps locking when I'm using it !!!

I don't know why your phone is locking up but you might want to try Screebl in the marketplace. It might help. Good luck!

 

Are you using an app that disables the screenlock?

 

Yea, figured No Lock would be the culprit. I have it on my D2 and the app glitches once in a while. What I have found that does the trick (with No Lock) is I place the No Lock widget on a homescreen and maybe once a day simply enable it, lock my screen, then wake the screen/unlock it, and then finally go back to the widget and disable.

No need to un-install and re-install, its a useful app........and it is free. If you are looking for another app that does the trick and doesn't glitch like that I would recommend Extended Controls.

 

my lenovo keeps locking itself too.. i already downloaded screebl but it useless. how can o overcome it please!!!!!!!!!! help me!!!!

 

Well, like the OP, do you have a lock assist app installed?

 

I've been using my 2015 samsung galaxy j5 for about two years now and very recently I've experienced an issue like this one and my phone goes to the lock screen and says the connected to *my internet* and i haven't downloaded any apps such as 'No Lock' and i would really appreciate some help for this issue. The only thing i think it could be is the app 8-ball Pool. i got the app a week ago and around the same time this issue started occuring. i may need to factory reset my phone but i hope it doesnt resort to that

 

try

1. Turn off the Samsung Galaxy J5;
2. Press and hold simultaneously the Volume Up, the Power, the Home buttons;
3. When the Android logo shows up and the phone vibrates shortly, let go of the Power button and keep holding the two others;
4. When you’ve entered the Recovery Mode you can let go of all the buttons and start scrolling down from the Volume Down button;
5. Select the Wipe Cache Partition;
6. Tap the Power button;
7. Select Yes;
8. Tap the Power button again;
9. Wait for it to wipe the cache and reboot;
10. Since you’ll still be in the Recovery Mode, select the Reboot System Now and this one will bring you to the normal running mode.

I had the same problem with my Samsung s 5 mini and couldn't fix it. It seems I tried all the methods...
