Android Mobiles : Tips & Tricks

We have some android mobiles which need some tips & tricks to work smoothly.
I get many questions from fellow members and friends to sort out the problem.

Ask here if you have some problem
Give suggestions / solutions to solve the problems which we face.

I have some mobiles which I face problems with them regularly small or big.
Mostly these are software issues.
Hardware issues are rare.
Me & others can share our experience with you all.
Mobiles in Cold Weather normally tend to fail or shut down immediately.
You stand stunned when you suddenly feel that you opened your mobile to shoot a picture in a beautiful surrounding and mobile shuts down.

This is mostly due to cold weather.
New mobile can also get shut down.
But mostly old mobiles shut down.

Cold weather makes your battery to shut down as sudden temperature change can make battery fail.
This happens with most electronic gadgets like Mobile, Camera, Remote, etc. (Cars can also have thermal shock/)

1. Keep your mobile inside a pocket in shirt so that it gets regular heat from your body without exposing to outside weather.
2. Keep your mobile out for short duration only.
3. Try to use a Flip cover as it covers mobile from both side like a blanket.

If you know more please suggest.
Other than throwing mobile !

Mobile gets jam or hanged.
Mostly this is due to cache memory being filled up to full.
Old mobiles mostly had less memory and are tend to fill shortly.
those who use whatsapp more feel the pich early.

Use cache cleaner to clean the temporary files.
Power Clean is also such cache cleaner with less memory space.

Or if you don't have enough memory then ?
A short cut is here.
Goto Settings>>Storage>> Cache Memory>> Clean

In some mobiles like having Jellybean etc.
Touch cache memory, it will show clean option.

In MIUI cache cleaner is already ther. Use it.

Oplus XonPhone 5 Full In-Depth REVIEW (1.3Ghz Quad-Core | 8MP | 5" Display) - TekhSquare

Oplus XonPhone 5 Unboxing & First Boot - PhoneRadar

Looking for some solutions.
It is dead, not getting up at all.
Battery is fully charged.
Tried many tips & tricks but it is dead.

Some Options / Remedy:
1. This solution worked for one time only after some attempts.
Oplus Xonphone 5 Hard Reset
  • Switch off the phone
  • Connect Charger and Press Volume Up + Power for recovery menu
  • Now press power button to see the recovery option
  • Volume Down and select wipe data/factory reset
  • Press Volume Up to OK

It worked for few times.
Keys are little bit tricky to operate.
Try finger nails to press volume up or down button at its edges, to middle of button.
It works with little hard work.
I am able to do after several attempts.

It seems its software needs to flashed with original ROM.
But friend got it flashed earlier few times.

Now again same thing is happening.
Seems custom ROM like MIUI 8 stable version may work.
If it still not works then it seems to be hardware issue which is making it to go dead after sometime.

Xonfone original battery is not available.
You can try other battery of Spice model.



Option / substitute of battery of Oplus Xonfone 5:
as suggested here:

For Oplus Xonphone 5, I used the Intex BR2075AD for Intex Aqua I7 With 2000mAh. The specifications are the same and fits nearly well. Only, you may have to add support at the bottom of the battery as the height is lower (shop guys fixed this with a plastic wire).
as user^

Available at ebay india:

Spice SCRB-16 is
Spice also has similar battery, but you have to put paper to fill the gap at lower end.
a user^

But I went to karolbagh gaffar market and paid 450 for spice battery which had some gap at end but they put plastic filler.
Battery is of 1500 mAh only.

Try at your own risk as some codes ae meant for Engineers only.

I had to flash Xonfone 5 as it was dead from more than 6 months.
It was not getting on.
Stuck on logo only.
Software upgrade / Flash was needed.

ADB MTK Driver

Original Firmware

Check / download from here :

After downloading above 3 things.
I installed USB Driver for MTK device.
Then installed SP Flash Tool.
When SP Flash Tool got installed, mobile needed to be off.
Then connect Mobile to PC via USB cable.
Now as shown in video
I just find the scatter file in OPUS Original Firmware folder.
Checked for Upgrade only.
Then pressed download.

All was done automatically.

And it was done easily in sometime.

Xonfone 5 is a friend's mobile.
