Issues with zenfone 2 laser ze550kl

Hi Suraj,

1.the phones becomes lagay.. A lot. If a app is updating in background then you are not able to use you phone.. Because it becomes in responsive..
Ans: During application updates kindly check the RAM memory of your device and make sure that most of your apps are already clear from the recent task list. We would even ensure to update those apps regularly for better performance.

2. The heating issue arrised in the phone..
Ans: As mentioned above, you will need to check your background running apps as they should be cleared if not in use after moderate usage of gaming and continuous browsing on 3G/4G may heat up the device. We would suggest to check if battery even heats up. If it does, you will need to check the battery at the authorized service center.

3. The phone freezes during many processes/apps.
Ans: As we mentioned in the above first issue, this confirms that the RAM memory on your device and CPU processes maybe running continuously on background. We would suggest you to use the mobile manager app so that apps which are running under background would stop until and unless the app is selected for usage.

4. And obviously the battery draining issue still presist..
Ans: You can use two apps where you can control your app usage as well as increase battery life. Go to settings> battery> select top right corner> tap on three dots> select power saver and you will have list of options where you can select to optimize battery usage.

If the issue persist we would still suggest you to monitor this issue under safe mode for couple of days.
