1. The blocked contacts app
This is one of the most common issues with the new update. If the message arrives the contacts no longer work, it is best to eliminate the application cache memory. To do this, just go to Settings > More> Application Manager> All. There you find Contacts and click on it. A window with application information appears, where the option will be Clear Cache. If the problem still persists, try erasing the application data.
Obviously, this solution fits any application lock.
2. The service com.android.phone stop working
If an error message appears stating that the com.android.phone stopped, you can solve the problem by Settings > More> Application Manager. Then just click the menu button (below left) and select Reset app preferences.
It is also advisable to enter Safe Mode to find out if the error also recurs. In it are only applications that arrive in series with the device. That way we can find out if the system problem comes from a third party app. If the error message does not appear in Safe Mode, then we should check the applications we recently installed. It is best to uninstall them one by one to see if the problem persists.
Of course, if the problem hits many users, Samsung will launch a patch to solve it.
3. Loss of battery
Another of the most common issues after performing the upgrade. Usually excessive battery loss usually occurs during the first few days after the update, and then the device returns to normal. If this is not your case, you can try various solutions, such as turning off the Galaxy S4 and turning it back on after 5 minutes.
You can also go to Settings > Application Manager and proving which applications are consuming RAM, and in Settings > Battery, to check which ones are overcharging the battery. This way we will know if the system or application problem.
If this does not help, restart the device in Recovery Mode (with S4 off, click on volume up button + Home + power button) and delete the cache partition via the wipe cache partition option. If the problem persists, you will have to take drastic action. Yes, we are talking about a data restore, but not without backing up your data first!
You can perform a factory restore from Recovery Mode or from the menu. Settings > Accounts> Backup & Restore.
4. Delay and slow app launch
It is also quite common for the device not to function smoothly after an upgrade. We can try to turn it off and remove the battery for 30 seconds. This is sometimes enough for the problem to go away. However, if delays persist, it is best to make a wipe from the cache partition. Once again, let's go to Recovery Mode (we turn off S4 and turn it on by clicking at the same time on volume up button + Home + power button). Once inside the menu, simply select wipe cache partition.
Other tricks to avoid the lags And getting Galaxy S4 to improve its performance is, for example, disabling window animation, transition and animation duration from Developer Options. To enable them, go to Settings > About the device and click the build number several times.
It is also advisable to disable direct access to S Voice from the start button. It often causes a delay because the system always waits a moment to see if we want to open S Voice. To disable this option, open S Voice and click the menu button. You will find the option Open with the start screen.
5. The keyboard disappears
Many users have commented that one of the problems with updating is the disappearance of the keyboard while writing a message. A possible solution can be found at Settings > More> Application Manager> Running. Locate the Samsung keyboard to check for any error messages. If so, you can download an alternate keyboard app. We highly recommend SwiftKey.
6. Problems with Wi-Fi Connection
Another usual problem after an update. To solve this error we have a series of simple processes: disconnect and reconnect the Wi-Fi connection several times, enter Airplane mode for a moment, forget the connections (and add them again), restart the router, disable Smart Network, etc.
7. Problems with Bluetooth
Also quite common and without any precise solution so far. It is best to turn Bluetooth off and on again. Sometimes the solutions are in the simplest action. If this does not work, you will also disable and re-enable pairing with your Bluetooth devices.
8. Overheating Problems
Some Galaxy S4 users say they have overheating problems after the upgrade. The newsroom device running Lollipop did not present this problem. If your S4, just remove the battery and microSD card and insert them again. At the moment, this is the only solution for eventual overheating, and can be a nuisance for those who use external memory a lot.
