J7 Overheating After Getting Wet
Problem: please help me my sumsung j7 prime is overheating because it falls down into water i can only use the contact and all the other apps don’t work and i can’t charge it. Also, the sound doesn’t work I just turned off my phone. please I need your help
Solution: Since your phone got wet then the best thing that you can do right now is to make sure that the phone is dry. If your have the variant with the removable battery then I suggest that you remove the battery of your phone. In case you have the phone with the non-removable battery then leave it as it is. You should also remove the SIM card and microSD card of the phone. Turn off the device then place it in a bag of rice for at least 48 hours. The rice will absorb the moisture inside the phone. Once this is done try checking if the issue still occurs. If it does then the phone might be water damaged already in which case you will need to bring this to a service center and have it checked.
J7 Screen Brightness Is Low Turns Off On Its Own After Rooting
Problem: Hi. I have Samsung Galaxy J7. I wanted to flash a fresh stock ROM in the device because it was lagging so i rooted the device by installing I-Root application Play Store and rooted the device. I successfully rooted the device which i made sure by checking it from a root checker application from Play store. I then installed Quick Reboot (ROOT) application from Play store and granted root access to the application and restarted the device into recovery through this application. Since then the device is non-responsive when i try to power on the device by pressing power key the screen shows very low brightness and then turns off. when i put the device on charging no led notification is showing but the phone is heating up which shows its charging. I have tried to connect the device with computer through data cable but same happens screen shows very low brightness and then turns off, computer shows installing drivers for your device and then says device is disconnected. I have tried all key combinations for entering into recovery, download mode etc but in vain the response is same as above i.e. screen shows very low brightness and then turns off. I am very upset and want to fix it myself please help. Note: Device is not liquid or break damaged it’s just that which i explained above. Please Help!!
Solution: It looks like the rooting process might have corrupted the phone software. The best thing that you can do right now is to flash the phone with its updated firmware file. You can get the firmware file from the Sammobile website. You can also get the instructions on how to flash your phone from this website. Take note though that when you flash your phone your personal phone data will be erased.
J7 Completely Frozen
Problem: My phone is completely frozen, power button not working and screen is stuck cannot do anything to turn off or reset please help
Solution: If you have the model with the removable battery then I suggest that you remove this. You should also remove the microSD card of the phone if you have one installed. Once this is done press and hold the power button for at least a minute. This will discharge the phone circuit and clear out its RAM. Reinsert just the battery then turn on the phone.
In case you own the model with the non-user removable battery then just remove the microSD card of the phone then press and hold both power and volume down buttons for at least 10 seconds.
In case the issue persists then proceed with the steps listed below.
- Start the phone in Safe Mode. When your phone operates in this mode only the pre-installed apps are allowed to run. Check if the issue occurs in this mode. If it doesn’t then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
- Try wiping the cache partition of the phone from the recovery mode.
- Start the phone in recovery mode then do a factory reset. Take note that the reset will erase your phone data.
In case the above steps fails to fix the problem then you will need to bring the phone to a service center and have it checked.

J7 Screen Flickers And Freezes
