The Samsung i9100G screen is not working, it is very stuck, but it is fine after plugging in the cha

The voltage is unstable, is there something wrong with the battery?

Hello: According to your description, it is recommended that you try the following steps:

1. Clean the contact points of the battery, mobile phone battery and the charging jack on the mobile phone, and check whether the contact points are broken.

Welcome to Samsung's Digital Services platform.

The mobile phone is disassembled on a motherboard, there is a power control chip on the motherboard, it should be a problem with this chip, go to the after-sales service to check, if there is really a problem here, you can change the phone, a motherboard is very expensive and expensive.

It is not ruled out that there is a problem with the system, so back up the phone and restore it to factory settings to give it a try. Or if you have installed any software recently, uninstall it to see.

Is the charger broken, do you want to try another one?

Hello! The following two scenarios are for reference:

First, the comparative method. 1. Change the battery to be fully charged in the same charging dock to see if the phone shows full charge. If it is full, explain the reason for the original battery.

2. Put the original battery that is full in the charging dock and install it in another i9100 mobile phone, if the display is full, it means that the circuit of the mobile phone display power part is faulty.

2. More professional test methods: 1. Test the battery with a multimeter, if it is between, it means that the battery is indeed full, which also means that the circuit of the mobile phone shows that the power part of the circuit is faulty. 2. Use a multimeter to measure the positive and negative charging contacts in the charging dock, if it is on the left and right, it means that the charging dock is OK.

I hope the above can help you! Good luck!

Touch screen drift, this is a more common problem, you try to flash whether it can be solved, mine is also solved by flashing.

Use someone else's mobile phone of the same model and your own charger to see if this happens, if it is normal, it means that the charger is good, your own mobile phone has a problem, if there is a similar problem, it is a problem with the charger.

No, it's a charger voltage issue or a contact issue. It's better to change the charger.

Hello! i9100 This is the case, you can use the elimination method:

Find a universal charger with good quality, charge the 2 batteries separately, if the phone is fully charged, the mobile phone still shows low power, then it can be basically determined that the mobile phone system recognizes the battery power part of the circuit fault, and the machine can be solved by brushing the machine.

If one is normal and the other is abnormal (the battery is still low) after being fully charged, it means that the abnormal one has aged the battery cell inside and cannot be charged.

In addition, if you want to have a longer standby time than the original battery, you can also find a large-capacity battery, so you don't have to charge it every day.

I hope the above can help you!

It's your battery problem. Every time you want to use the battery to 10%, you can't charge it. If you don't run out of points, you will charge it every time, and you will use electricity very quickly.
