Right after the rollout of Google Nexus 7 Android 4.2 update, many users complained their device’s performance turned sluggish and that they often experience lagging and freezing. There could be some other underlying issues but it’s clear that there are a lot of compatibility issues with the latest Jelly Bean.
In reality, Android apps don’t need to be to become compatible with new Android versions but one of the things that would surely make an impact is when system directories are changed.
Data caches are saved in specific directories where apps can easily access them. When they’re changed, the nightmare begins. Although this problem happens to a few select apps, it would still make an impact on system performance because cross-referenced data could no longer be found. That’s the reason why some apps are reset to their default settings after the update.
Now, to fix app-related lagging and freezing, here’s what you should do:
- Find the app(s) that lags and take note of its name.
- Go to Settings => Device => Apps => find the app and tap on it.
- You must be seeing, at least, four buttons: Clear Data, Force Stop, Clear Cache and Uninstall.
- The first thing you should do is Clear Cache, then Clear Data and Force Stop the app.
- Then go back to the Home screen, launch the app drawer and launch the app you just forced-stop.
- If it was resolved by that simple procedure, that’s good. Otherwise, you’ll have to go back to the app Settings, uninstall it and re-install it back.
Clear Cache – you will be deleting data cached in the device’s memory.
Clear Data – it means you’ll be setting the app back to its original settings.
Force Stop – is to stop the app from running temporarily.
If the performance won’t improve after doing the procedure above, we suggest you do a factory reset. Follow instructions below:
- Go to Settings.
- Choose Backup & Reset.
- Tap Factory data reset.
- Touch Reset tablet.
- Depending on the security measure you used, you will be prompted to enter your password, PIN or pattern.
- Tap Erase everything to confirm your action.
Of course, before you actually reset your device, you need to back up everything in your tablet.
