I am new to this forum and do not know much of the technical terms. So here is my problem as best as I could say...
I have a unlocked Samsung S4 purchased last Sept (Philippines/SE Asia version, I think). The phone worked fine until the latest upgrade to Kitkat 3 weeks ago.
A week after the upgrade, the phone started rebooting itself. After checking this forum, it looked like a battery problem. On checking, it did have a swollen battery. At the same time, the S4 stopped working as a phone - meaning I could browse, use apps, but could not make calls.
First changed the battery with an original from Samsung, hoping everything would sort out. Unfortunately, it did not. The phone still kept restarting and the network signal showed as not available. So I went to my provider and got a new SIM card and changed it.
Unfortunately, that has also not solved my problem.
Now, my phone keeps rebooting itself. If I connect it to the charger, then the phone starts successfully. At times, it behaves well, but suddenly/randomly, if I touch an app (any app, no pattern) it will reboot again. Once it starts rebooting, it keeps doing that in the screen which has the samsung music comes - it would turn off again and keep restarting until that screen reaches again. Only if I connect to the charger would it start. Again, there is signal at times and there is no signal most of the times. My area has good network signal, so that should not be the problem.
I tried clearing the cache and clear all data/apps, but still no luck. Also, my battery still has / holds charge - so that is not the problem.
Could somebody please help me!!! Please let me know if you need any other details regarding this.
