Parse Package Error on Galaxy S7

You might also be experiencing Parse package error when trying to install apps from unknown source. The best approach for such is to make sure that “Unknown source” is enabled on your device. Also make sure that the app you’re installing is compatible with your device operating system, as known, not all old or outdated app would work on marshmallow operating system which the Galaxy S7 uses.

Unfortunately app has stopped on Galaxy S7

There are various approaches for this type of error. Firstly, make sure that you clear the cache and data of the application. Simply go to Settings >> App >> All >> appname >> clear cache and wipe data, restart your device and it’s solved. Alternatively, you’re to re-install the application on your device. If the same issue also happens to most applications on your Galaxy S7 device, then the best option is to hard reset your device. To hard reset Galaxy S7 smartphone, simply switch off your device and then press & hold the Volume up button, the Home button, and the Power button together until you see the Android on screen, use the volume down button to get to the wipe data/factory reset option and then the power button to select the option. Remember to backup your device data before you hard reset.

Overheating Issues on Galaxy S7

Maybe your Galaxy S7 device might be experiencing overheating problems. Anyway, there are various approaches for this type of problem. Firstly, boot your Galaxy S7 device to safe mode. I already detailed an article on how to boot Galaxy device to safe mode, I advise you go through the guide. This would also solve lag issues and freezes on the device. Alternatively, you wipe the entire cache of the smartphone. To wipe the entire cache of the smartphone, simply boot your device to recovery option, and then you select wipe cache partition and proceed to clearing all cache on the smartphone.

Fix Galaxy S7 Wi-Fi Problems

To fix Wi-Fi problems on Galaxy S7, simply boot your device in safe mode and restart. Alternatively, you can go to an already connected Wi-Fi click forget, input password and re-connect. Also ensure that the “Always allow scanning” is enabled and make sure that the Wi-Fi is kept on during sleep.

How to Fix Galaxy S7 GPS Problems

I know that most of you might be experiencing GPS issues on your Galaxy S7 device. Anyway, the best approach for this is to Settings >> Personal tab and select Privacy and safety >> Location >> Location method then try using Wifi GPS and mobile to track mobile. You can also try WIfI and mobile, if it still doesn’t work, use GPS only. You can also toggle location on, off and then on. Alternatively, you can clear cache at application manager.

There are various methods to deny your device root access. I’ve already published an article on how to unroot android devices, I advise you go through the guide if you wish to unroot your device without losing a single data on your device. Alternatively, installation of stock firmware or rom on your device can solve both hard bricking issues and also unroot the device.

follow the guide here to unroot your device.... once you've installed the twrp recovery then use the dm-verity and force encryption disabler to leave device unrooted..

I got my S7 (930F) today. I went through the 1st time setup and evrythin went smooth until my phone decided to reboot and got stuck in some kind of reboot loop.
As i searched google i read that i was no uncommon problem with samsung devices so i tried some of the things suggested (factory reset/cache whipe) .. nothing worked.

It just tried to boot, loaded my carrier homescreen for a second and went back to the Samsung Galaxy S7 powered by android screen and would do tht over and over.

So i tried to do a firmware update via Kies , looked like it worked but still ... wouldnt boot after.

Maybe the best way would have been to return it to my carrier and get a replace but since i am little bit techy i decided to search some more.

So i ended up flashin

2016-04-18 Austria (3 Hutchison) 6.0.1 G930FXXU1APD1 G930FDRE1APC3

this firmware (found on sammobile) via ODIN 3.10.7 and everything worked but still no boot , still stuck on the Samsung Galaxy S7 screen.

Did i total brick my phone? What else can i do?
Running out of ideas, any help would be great!

Hello, my Samsung Galaxy S7 Edge just got bricked. I tried to un root it with SuperSU but just go to the Samsung Galaxy S7 powered by Sndroid Screen over and over again.

I am planning to install the official firmware but my phone is the international version, so I do not have a special carrier or a ''country'' so my doubt is, what firmware should I download?

I need the G935FXXU1APB6 but when I find them, there are a lot of different countries with that firmware.

Which one should I download?

Thank you very much.
