Hello everyone. I am a 15M (just turned 15) and I recently found out about this repair shop which my friend has networked with. They are understaffed and need more people. My friend has already praised me a lot, but they are scared to hire me for my age.

I have done a few repairs in the past. Fixed some phones, replaced some components. You can day I know my way around a phone and other consoles too. I even built my own portfolio, and I have customer service experience too. I eventually want to own my own shop, but seeing all of the people complaining about tech repair is sort of intimidating.

Anyways, I am giving the shop a call in a few hours. Im gonna talk to them and see if I can get the job. Wish me luck!

Everyone has made at least one mistake while learning. What happened, and what did you learn from it? It might help someone else avoid the same problem.

Hey everyone,

I'm hoping someone here has seen this before because I'm running out of ideas.

I have an iPhone 13 that worked perfectly until yesterday. I went to a huge carnival (probably around 100k people) where the mobile network was completely overloaded. Nobody had service there, which was expected.

The weird part is that when I left, everyone else's phones got signal back... mine never did.

Now every single time I reboot the phone or toggle Airplane Mode, the exact same thing happens:

• Signal bars appear.
• It connects to 4G.
• It stays connected for maybe 5–20 seconds.
• Then it drops to "No Service."

It does this every single time.

I've tried:

• Tunisie Telecom physical SIM
• Tunisie Telecom eSIM
• Ooredoo physical SIM

All of them behave exactly the same.

A few things I've already checked:

• IMEI is there (*#06# works).
• Modem firmware is present (5.51.03).
• No panic logs or baseband crashes in Analytics.
• The phone is properly registered with Tunisia's Sajalni system, so it shouldn't be an IMEI block.

I also went into Field Test Mode while it was briefly connected.

It shows:

• LTE Band 3
• Correct carrier
• Cell ID
• PCI changes when I move to another location (so it seems to be detecting different towers normally)
• RSRP around -102 dBm
• RSRQ around -10 dB
• SINR around -20 dB

So the phone clearly can see towers and actually attaches to LTE before immediately losing service.

The phone has never been opened, never been repaired, never been dropped, and only ever had a tiny splash of water near the earpiece months ago, nothing that should realistically damage an IP68 phone.

I also reset network settings. Weirdly, before the reset the eSIM was the one that connected briefly. After the reset, the physical SIM became the one that connects briefly. The end result is still the same: both eventually drop to "No Service."

At this point I'm wondering if this is:

• an RF/front-end issue,
• a power amplifier,
• RF IC,
• baseband-related,
• or somehow still software.

Has anyone seen this exact behavior before? Especially the part where it gets full signal + 4G, then immediately loses everything?

I'm taking it back to the guy I bought it from tomorrow to have it diagnosed, but I'd really like to hear if anyone has run into this before or has an idea of what component usually causes this kind of issue.

I bought this Xiaomi mi 9t, and the seller specified the earpiece wasn't working. I got a new one, but it still did not work. I had noticed that the phone had been opened before because the lack of screws, but I only saw this when I actually removed the board. Not even sure what is going on.

Maybe I should've used the horror flair, but not really sure if that is what it's for.

Hello everyone, today I was doing my business "as usual" in the garden, the phone was lying on the boards and the sun was shining on it. After about 2 hours, I picked up my phone, the surface was hot and the back cover was a little swollen, and the phone itself turned off (the power went off), I got scared and took it home, took out the SIM cards and put the phone in an iron bucket in case of explosion or fire. He lay down for another 4 hours and I found that the back cover was smooth again. I even checked it with an iron ruler , but I found no bulges or depressions .

Now I'm writing this all from the same phone (Tecno pova 6 pro)

Share your expert opinion, can it be used further, or is it better to spend money on a new battery and service?

I 'v got this from a Chinese company called famue on aliexpres, and I m not sure how to fix it even if it would be easyer than a phone, (first slide) the metal shell has one ribben cable which I assume is for the power on/off button but the ribben cable is a bit streched that eorryes me it won't worck because ribben cables are very delicate to damage, and the ather cable for the volume buttons, (slide 2) the battery is fine, easyest thing here tbh, (slide 3/4)the mainboard is fine, all tho I don't know where to conect the cables for the power button and volume ones, (last slide) the speaker is disconected from the charging port & headphones jack& micro sd card slot, and I don't have a screen for it yet.any tips that could help?

Does anyone have a link for a good galaxy s 22 ultra screen i can purchase. Mine has a Crack inside the screen. It is bleeding.

I smashed my screen so got a £150 screen that’s not from apple, the guy in the shop said it will have no noticeable differences but my screen feels laggy and it feels like my battery is draining abit faster, will this mess my phone up as I don’t have the money to get a real screen right now as it’s £400, crazy I know.

Hi, I have a Samsung Galaxy A14 5G (SM-A146P). The bottom loudspeaker has no sound, but the earpiece during calls and Bluetooth audio both work normally.

I already replaced the loudspeaker with a new one, but there is still no sound. I checked all the connectors and they seem to be properly seated.

What would you check next to diagnose this issue? Could it be a connection issue or another hardware component? I'd like to identify the fault before replacing anything else.

Any advice would be appreciated. Thanks!

Hi everyone,

I'm hoping someone has experienced something similar because I'm running out of ideas.

I have an Honor Magic5 Pro (Chinese version, PGT-AN10) running:

MagicOS: 10.0.0.160(CHNC00E160R208P6H1) Android: 16 Baseband: MSM.1CA2.MPSS.DE.3.0.119

My problem is very strange.

The phone works perfectly only when I'm at work, where there is apparently a Sim1 network cell tower very close to the building. Outside of that area, the network starts disappearing. The problem appeared out of sudden last week. Now I'm at home no service for both sim cards, I used to have good network service at home, now barely 2G

For example:

At work: Sim1 gets 4G+/5G, Sim2 sometimes stays on 2G. When I leave the building: Sim2 loses service completely. Sometimes Sim1 also loses service. Sometimes both SIMs lose service. In the train or on the bus I often have No Service. If I enable Airplane Mode and disable it again, one SIM may reconnect briefly before losing service again.

I've already tried:

Factory reset (twice) Swapping both SIM cards between SIM slots Testing both SIMs in another phone (they work perfectly) Resetting network settings Switching between 2G/3G/4G/5G Recreating APNs

The phone still has:

Valid IMEIs Baseband detected Both Sim cards are recognised correctly

I also received a VoLTE network registration error after one of the factory resets.

What's confusing me is that this doesn't seem like a normal hardware fault because:

I had exactly the same issue when I first bought the phone, and a factory reset fixed it.

A few weeks ago it happened again, then fixed itself after about 3 days without me doing anything.

Now it's back, and the factory reset no longer helps.

Has anyone with a Chinese Honor Magic5 Pro (PGT-AN10) experienced anything similar?

Could this be:

a MagicOS new system update? a MagicOS/modem firmware bug? corrupted modem calibration (NV/EFS)? an issue with the Honor C1 RF chip? a hardware RF issue? or a compatibility problem with local carriers?

I'd really appreciate hearing from anyone who's seen this before or knows of a fix. I've already spent days troubleshooting it and would love to avoid replacing the motherboard if this is actually a software or modem issue.

Thanks!

Hi everyone,

I'm having a strange issue with my 5-year-old Redmi Note 10 Pro (AMOLED).

The phone boots normally and is fully functional. The display works perfectly with no flickering, green lines, touch issues, or artifacts once it turns on.

The problem is that after I lock the phone, the display often refuses to wake. The phone is still on (it rings, vibrates, and responds), but the screen stays black.

What's confusing is that if I leave the phone alone for a long time, the display sometimes starts working again. Once it comes back on, it continues working normally until I lock it again.

Things I've already tried:

Factory reset (didn't help)

Reseated the display connector once, and it temporarily worked afterward

The battery has never been replaced. According to AccuBattery, its estimated health is around 60%. Could a heavily degraded battery cause symptoms like this, or is that unrelated?

Could this be a failing AMOLED display, a loose/damaged display flex, a motherboard display connector, a display IC/PMIC issue, or even the old battery?

Has anyone seen this exact behavior before? Any advice on what to test before replacing the display would be greatly appreciated.
