Problem #1: Calls keep on dropping when using Samsung Galaxy S4 of Digicel

Ok. So I’ve had my S4 Active for about 8 months now and all I have are problems. I link them back to when it fell and the screen cracked (which I haven’t fixed so that might really be the issue). So it fell about 2 weeks after I got it. It still worked fine, everything was still great except for the cracks. That is up until recently. I went home for Christmas and I have been having network problems. I thought it was because of my location but anywhere I go it doesn’t change. I can make calls and then couple seconds after it will drop. I can make a call and right after I hang up I see that stop sign where my bars should be. Then I have to wait for it to come up. My phone freezes sometimes when trying to make calls. I see (something like that) has stopped working. One time I removed my battery and put it back only to get a black screen with the android mascot lying down with error on it and then I got options to reboot etc. I just selected reboot because I didn’t know what to do. I also tried to get a software update and I got a little message saying “DM initialization not ready. Check network or SIM card”. My battery  also drains ridiculously fast. It’ll only last if it’s in airplane mode. Also I can’t access my Gallery. If I use Photos to view my pictures I can but not Gallery no idea why. I really hope you can help me figure this out. Thanks for reading and if I missed anything or there’s something you don’t understand please let me know. Thanks in advance.

Below is just extra information:

Solution: Hi Kerry. If all these troubles started happening after you dropped the device and cracked its screen, they may all well be the side effects of that incident. The severity of the damage can only manifest itself in symptoms like the ones you described afterwards.  There’s no telling what might happen after a drop but in your case, we can safely assume that it was bad because it affected multiple functions.

We noticed that the issues you mentioned appears to be not connected to each other, which is a strong indicator that there’s probably a general hardware failure going on. The network issues you have noticed is probably because of a failing antennae while the black screen issue you get after rebooting the phone can be a sign other damaged parts.

The best way to identify whether or not there’s a hardware issue is by performing a factory reset. Also known as a hard reset, doing this procedure ensures that the phone’s firmware is restored to its original state, which is guaranteed to work properly. If problems remain after doing a hard reset, you can safely assume that you have a hardware problem at hand. In this case, it’s best if you can have the phone checked by a professional or have it replaced.
