How to troubleshoot your Galaxy A7 that keeps freezing and lagging
Based on my personal experience, these problems can be fixed easily since it’s only a minor issue with the system. However, if they occurred after you dropped your phone on a hard surface or left it submerged in water for a while, then there’s always a chance that they’re a result of either physical or liquid damage. In such case, it’s useless to troubleshoot your device. Your best option is to bring it to the shop or back to the store where you bought it so that a technician can check it for you.
Now, assuming that the freezes and lags started without apparent reason or cause, here’s what you should do about them…
Reboot your phone – I don’t know if you already did restart your device but if still not, please try it. I encountered cases before wherein freezes and lags were caused by some minor glitches in the system and we all know that the best solution to glitches is a reboot. So, take time rebooting your device to know if the problems are fixed with it. If not, try doing the Forced Restart by pressing and hold the volume down and power keys together for 10 seconds or more. Your phone will restart like it usually does but its memory is refreshed as all apps, services and core functions will be reloaded. If the freezes and lags still occur after this, then move on to the next solution.
Find out if these problems are caused by third-party apps – yes, that’s right, third-party apps may also cause your phone to freeze and lag. In fact, more often than not, third-party applications or those that you download from the Play Store cause more performance issues than pre-installed apps. For this, you need to run your Galaxy A7 in safe mode to temporarily disable all third-party apps. If your phone performs well while in this mode, then it means that there’s an app or two that causes all ruckus. Try to find that app and uninstall it. This should be the ultimate solution to a problem that’s caused by third-party apps. However, if the freezes and lags continue even in safe mode, then your phone might be having some issues with its firmware. Move on to the next solution.
Wipe cache partition – another possibility we need to consider is the fact that these issues might have been caused by some corrupt system caches. These files are very small but they work with the firmware to make your phone and its apps run smoothly. If some of them got corrupted or became obsolete and the system continues to use them, issues the ones we’re tackling here may occur. The best solution for this problem is to delete the system caches so that they will be replaced with new files. Don’t worry, all you need to do is wipe the cache partition to delete them and the firmware will take care of the rest. After wiping off the contents of the cache partition and your phone is still freezing and lagging, then you have to do the next solution.
Backup your files and reset your phone – a reset will take care of all apps and firmware issues including freezes, lags and crashes. However, we’re always hesitant to recommend it to our readers if we haven’t exhausted all possibilities because of the hassle it entails. In this case, however, you have no other choice. So, make a backup of your important files and data and then reset your phone to make your phone work perfectly again.
