Problem :   So my phone keeps restarting itself and it’s getting pretty annoying I have tried taking out the battery and even changing batteries I have even did a factory reset and the issue has lightened up but it’s still restarting by itself usually when I leave my phone alone I don’t know what to do.   Please help! Troubleshooting : Based on your description, I can extract at least two possibilities: firmware issue and app-related problem. It’s one of those cases wherein we need to rule out the possibility of a firmware issue and that said, I want you to do the reset again and this time do the master reset via recovery mode.

When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key. When the Android System Recovery screen appears, release the Volume Up and Home keys.

Problem :   I have S5 SMG900H, but after I made a software change due it start to show several errors on my phone, but after that phone works fine for 10 minutes and then it was black out, no external key nothing works.   Phone seems like dead, after research I found the jtag, it let me reinstall the software but the screen still black.   Can you help me? Answer : I assume that when you said “software change” you meant manual firmware installation.   Well, if the phone worked perfectly before you did that and started showing those error messages after you finished whatever it is you did, then you must have done it wrong.   And by wrong I mean a lot of things: incorrect firmware, interrupted installation, corrupted firmware, etc. It seems you’ve already done a lot of things to your phone, so it’s time you sent it for repair.   It’s difficult for us to suggest things especially when we don’t know where to start because we might end up suggesting things t...

Frequent and random reboots or restarts can be caused by a lot of factors but the most common of them all is battery issue especially that it’s almost 3 years since Samsung Galaxy S5 (#Samsung #GalaxyS5) was released.   The battery may have already deteriorated to the point that it can no longer hold a charge Problem :   I’ve not entered the Android software because I don’t have enough time to get to settings when my phone turns on.   My phone keeps repeatedly restarting, I’ve read all your issues and this is different.   I turn it on and within 5 seconds it restarts again.   This is continuous, I don’t have enough time to do anything with 5 seconds.   I timed it and the longest it was on for was 7 seconds.   I tried taking my memory card and sim card out, turning it on and its still doing the same so it must be the phone.   I even tried safe mode and still does the same.   I cant try factory reset because I cant get to it to do that in 5 ...
